What a Structural Engineer Expert Witness Does in Florida, and the Daubert Standard

Mon, 05 Oct 2026 12:00:34 GMT

In Florida, a structural engineer's opinion only reaches the jury if it survives the Daubert standard in Fla. Stat. 90.702. For the attorneys who retain engineering experts, that makes the method behind the opinion as important as the opinion itself. This guide covers what a structural engineer expert witness does in Florida litigation, the standard the testimony has to clear, why that standard applies to engineers and not only to scientists, and what separates an opinion that holds up from one that gets struck.

What a Structural Engineer Expert Witness Does

A structural engineer expert witness investigates a failure or a disputed condition, applies established engineering methods, and forms an opinion a court can rely on. The work usually runs from a site inspection through a written report, a deposition, and trial testimony. Common matters include construction defect and workmanship disputes, structural failures and partial collapses, water intrusion and long-term deterioration, premises liability claims such as slip, trip, and fall, and hurricane or wind damage causation. The same forensic engineering investigation that establishes what happened is what supports the opinion later, which is why the two roles are so often held by the same engineer.

The Daubert Standard in Florida

Florida replaced the older Frye general-acceptance test with the federal Daubert standard. The Legislature amended Section 90.702 in 2013, and after several years of constitutional uncertainty the Florida Supreme Court formally adopted it on May 23, 2019, in In re Amendments to the Florida Evidence Code, 278 So. 3d 551 (Fla. 2019). Under Daubert, the trial judge acts as a gatekeeper, and expert testimony is admissible only if it is based on sufficient facts or data, it is the product of reliable principles and methods, and the expert has applied those principles and methods reliably to the facts of the case. The witness also has to be qualified by knowledge, skill, experience, training, or education.

Why Daubert Applies to Engineers, Not Just Scientists

Attorneys sometimes assume Daubert is a laboratory-science rule. It is not. In Kumho Tire Co. v. Carmichael, 526 U.S. 137 (1999), the U.S. Supreme Court held that the Daubert reliability inquiry extends to technical and specialized testimony, including engineering. That means a structural engineer's methods face the same scrutiny a scientist's would. The gatekeeping question is whether the engineering approach was sound, not whether the field itself is respected.

How the Frye-to-Daubert Shift Changed Florida Cases

The change from Frye to Daubert was not a formality. Under the old Frye test, only novel scientific evidence faced a gatekeeping check, and the question was narrow: had the method gained general acceptance in its field. Established engineering opinion largely passed without a reliability inquiry. Daubert widened the gate. Now every expert opinion, engineering included, can be tested for whether its method is reliable and reliably applied, and trial judges hold admissibility hearings to decide. The practical effect for Florida litigation is that methodology gets litigated earlier and harder than it used to. A motion to exclude an engineering expert is no longer unusual, and an opinion that would have survived under Frye on the strength of the expert's credentials can still be excluded under Daubert if the method behind it does not hold together. For counsel on either side, that shifts the work forward: the reliability of the engineering has to be built into the report, not defended for the first time at the hearing.

What Makes Engineering Testimony Hold Up

Courts weigh reliability using factors drawn from Daubert: whether the method can be and has been tested, whether it has been subjected to peer review and publication, its known or potential error rate, the existence of standards controlling how it is applied, and its general acceptance in the field. In practice, defensible structural testimony ties the opinion to accepted codes and standards such as the Florida Building Code and the relevant ASCE and ACI provisions, documents the data it relied on, and connects each conclusion back to that data. Opinions that rest on the expert's say-so alone, with no method shown, are the ones that draw a challenge and get excluded.

The Report and the Deposition

A defensible report states the facts and data relied on, the methodology, the standards applied, and the reasoning that links each of them to the opinion. When the report shows its work, the deposition becomes a defense of a documented method rather than a debate over an unsupported conclusion. Having the same engineer inspect the structure, prepare the report, and testify keeps the chain from observation to opinion intact, which is far easier to defend than a hand-off between separate people at each stage.

How to Vet a Structural Engineering Expert

Before retaining one, look at four things: Florida licensure and qualifications that fit the specific issue in dispute, a written methodology that can be documented and repeated, opinions that are tied to the facts rather than offered as pure opinion, and a track record of testimony that has survived challenge. An engineer whose reports already read like they were built for a Daubert motion is the one least likely to be surprised by one.

Common Questions About Engineering Expert Witnesses

Yes, and it is often preferable. Having the testifying engineer perform the inspection keeps the methodology and the opinion connected and easier to defend.

Threshold Building Inspections in Florida: The Special Inspector's Role Under Fla. Stat. 553.79

Wed, 30 Sep 2026 12:15:23 GMT

If you are permitting a building in Florida that stands more than three stories or 50 feet tall, the state requires a threshold inspector to oversee the structural work during construction. That role, the special inspector, comes from Fla. Stat. 553.79, and the structural inspection plan behind it has to be approved before your building permit is issued. This guide covers what makes a building a threshold building, what the special inspector actually does, who is allowed to serve, and how the requirement differs from the milestone inspection that applies to existing condominium buildings.

What Makes a Building a Threshold Building

Florida defines a threshold building in Fla. Stat. 553.71. A building qualifies if it is greater than three stories or 50 feet in height, or if it is an assembly occupancy over 5,000 square feet with an occupant load greater than 500 people. An owner can also voluntarily designate a smaller building as a threshold building to get the added inspection rigor. If your project clears either bar, the special inspector requirement attaches to it from the permit stage forward.

What a Special Inspector Does

Under Fla. Stat. 553.79(5), the enforcing agency requires a special inspector to perform structural inspections on every threshold building, following a structural inspection plan prepared by the engineer or architect of record. In practice, the special inspector inspects the structural load-bearing components against the permitted documents, confirms that shoring and reshoring conform to the submitted plans, and follows the inspection schedule the plan sets out. It is an independent verification role. The special inspector cannot act as a surrogate for the building official, the architect, or the engineer of record, and the role does not relieve the contractor of its own obligations.

The Structural Inspection Plan Comes First

The sequencing catches a lot of projects off guard. The structural inspection plan has to be submitted to and approved by the enforcing agency before the building permit is issued, not after construction starts. The plan sets the specific procedures and the schedule so the structure can be inspected for compliance as it goes up. One more detail worth knowing: Florida does not allow virtual inspections for threshold structural inspections, so these are performed on site.

What Gets Inspected, and When

The plan does not treat the building as one inspection at the end. It schedules structural inspections at the points where the work becomes hard to verify later: the foundations and footings, the load-bearing walls and columns, the primary structural frame, and the shoring and reshoring that hold formwork during concrete placement. At each stage the special inspector checks the work against the permitted structural drawings produced during structural design and analysis, and against the approved shop drawings. Catching a deviation at the frame stage is straightforward. Catching it after the next three floors are poured is not, which is the whole reason the inspections are staged rather than saved for the end.

Who Can Serve as a Special Inspector

A special inspector has to be a Florida-licensed professional engineer or a registered architect certified to inspect threshold buildings. The engineer or architect of record may serve as the special inspector as well, provided they are on the licensing board's qualified list. That overlap can simplify a project: our founder holds the special inspector certification, so M&P Consulting Engineers can both prepare the structural inspection plan and serve as the special inspector on the same building, keeping the plan and the field verification under one roof.

The Signed and Sealed Statement Before Occupancy

Before the certificate of occupancy is issued, the special inspector files a signed and sealed statement with the enforcement agency. It certifies that, to the best of the inspector's knowledge, the structural load-bearing components were built in compliance with the permitted documents. That statement is frequently the last structural item a building has to clear before it can be occupied, which is another reason the inspection schedule is worth planning early rather than compressing at the end.

Threshold Inspection vs. Milestone Inspection

These two get confused constantly, and they are not the same program. A threshold inspection applies to new construction of threshold buildings, runs under Fla. Stat. 553.79, happens during construction, and answers one question: was the building built to the approved plans. A milestone inspection applies to existing condominium and cooperative buildings three or more stories tall, runs under Fla. Stat. 553.899, happens at 25 or 30 years and then every 10 years, and asks whether the aging structure is still sound. If you own or manage an existing building, you are almost certainly looking for the milestone inspection, and our Florida Milestone Inspections Explained article covers that side in full.

Why the Timing Matters for Your Project

The practical takeaway is that the structural inspection plan and the special inspector both need to be lined up before the permit is filed, not sorted out later. The owner selects and pays the special inspector, but the inspector answers to the enforcement agency, which keeps the verification independent. Getting the plan approved on time is what keeps a threshold project from stalling at the permit counter or, worse, at the certificate of occupancy. M&P Consulting Engineers handles structural plans review and special inspections for threshold projects, so the plan is ready when the enforcing agency asks for it.

Common Questions About Threshold Inspections

It has to be submitted to and approved by the enforcing agency before the building permit is issued.

Is a threshold inspection the same as a 40-year or milestone inspection?

SB 4-D, SB 154 and HB 913: A Timeline of Florida's Condo Safety Laws and What Changed Each Time

Fri, 25 Sep 2026 15:27:59 GMT

Three laws have reshaped how Florida oversees aging condominium buildings since the Surfside collapse: SB 4-D in 2022, SB 154 in 2023, and HB 913 in 2025. Each one changed the milestone inspection and structural integrity reserve study requirements that condo and cooperative boards have to meet. If your building has a deadline coming, this timeline explains what each law did and, more to the point, which rules apply to you today.

The Catalyst: The Surfside Collapse

On June 24, 2021, Champlain Towers South in Surfside partially collapsed, killing 98 people. The failure of a 40-year-old beachfront condominium exposed how little standing oversight Florida had for aging residential buildings, and it drove the legislative response that followed. Every requirement below traces back to that morning.

SB 4-D (2022): The Original Framework

Passed in a special session and signed in May 2022, SB 4-D took effect immediately and built the framework from scratch. It created the milestone inspection under Fla. Stat. 553.899 and the structural integrity reserve study under Fla. Stat. 718.112(2)(g). The milestone inspection was required at 30 years, or 25 years for buildings within three miles of the coast, and every 10 years after that, with a Phase 1 visual inspection followed by a Phase 2 investigation if substantial structural deterioration turned up. The SIRS applied to condo and cooperative buildings three or more stories tall, carried an initial deadline of December 31, 2024, and, for the first time, made reserves for structural components something an association could no longer simply vote to waive.

SB 154 (2023): The Glitch Bill

Signed on June 9, 2023 and effective the same day, SB 154 fixed the parts of SB 4-D that proved unworkable in practice. It removed the automatic 25-year trigger for coastal buildings and set 30 years as the statewide default, while leaving local enforcement agencies the option to require a 25-year inspection where saltwater proximity or other environmental conditions justify it. It limited the requirements to buildings that include a residential condominium or cooperative, and set cost-sharing rules for mixed-ownership buildings. Recognizing the shortage of licensed inspectors, it allowed a team working under a licensed engineer or architect to perform the inspection. It also extended the initial milestone deadline to December 31, 2025 for buildings reaching 30 years on or after July 1, 2023, adjusted the SIRS component scope, and let a milestone inspection performed within the past five years stand in for the SIRS visual inspection. The official SB 154 bill summary lays out the full list.

HB 913 (2025): The Current Rules

Signed in June 2025 and effective July 1, 2025, HB 913 is the most consequential update since SB 4-D. It extended the initial SIRS deadline to December 31, 2025, clarified the "habitable stories" language that had confused which buildings were covered, and required the study to include a baseline funding plan that keeps the reserve balance above zero. It let an association that has completed its milestone inspection delay the SIRS for up to two budget years to prioritize the repairs the milestone identified, exempted four-family dwellings of three or fewer stories, and added an officer and director affidavit plus a 15-year record-retention rule. It also barred Citizens Property Insurance from covering associations that have not met their obligations. The HB 913 bill summary has the details.

What Applies to Your Building Now

Stripped of the history, here is the net. A condominium or cooperative building three or more habitable stories tall owes a milestone inspection at 30 years, or at 25 years if your local enforcement agency requires it, and then every 10 years. Miami-Dade, for one, has kept a 25-year clock for many of its buildings through its 40-year recertification program. The same buildings owe a SIRS, with the first one due by December 31, 2025 for most existing associations, or coordinated with a milestone due on or before December 31, 2026. Reserves for the structural components a SIRS covers can no longer be waived. Our Florida Milestone Inspections Explained article covers the inspection itself in full.

How the County Programs Fit In

The state law is not the only clock. Two county programs predate it and still run alongside it. Miami-Dade County's 40-year recertification, one of the oldest building-safety programs in the state, requires recertification at 40 years and every 10 years after, and it has kept an earlier cycle for many buildings. Broward County runs its own Building Safety Inspection Program, which starts at 25 years and covers nearly every building type, not only condominiums. A Miami-Dade or Broward condominium can therefore owe both a county recertification and the state milestone inspection, on separate notices and at separate filing offices, even when one engineering site visit can inform both. Sorting out which programs apply to your building is the first step, because the county and state deadlines do not line up on their own.

Common Questions About Florida's Condo Safety Laws

The 2025 law extended the SIRS deadline to December 31, 2025, clarified which buildings are covered, added a baseline funding plan requirement, and tied insurance and record-keeping consequences to compliance.

If your building is a condominium or cooperative three or more habitable stories tall, yes. County programs such as Miami-Dade recertification and Broward's BSIP may apply on top of the state requirements, depending on where the building sits.

Post-Surfside: What Changed in Florida Building Inspection and What Boards Still Get Wrong

Fri, 25 Sep 2026 15:27:46 GMT

What NIST Found

On June 22, 2026, NIST's National Construction Safety Team released its technical findings . The team concluded that the collapse began in early June 2021, when two connections between garage columns and the pool deck slab failed. Over the next three weeks, cracks grew and loads shifted in the pool deck to neighboring slab-column connections that were not strong enough to carry them, which led to the collapse on June 24.

NIST describes the failure at those connections as punching shear, in which the slab bends and cracks around a supporting column until the connection fails. On the day of the collapse, in the scenario the team considers most likely, the failure spread through the pool deck and the street-level parking structure, the pool deck slab broke away from the face of the tower, and the damage that caused to two connections supporting the tower allowed the failure to progress through its middle and east sections.

The team attributed the building's vulnerability to margins against failure that, in the words of co-lead Judith Mitrani-Reiser, were too narrow from the start. NIST identified these contributors.

What NIST Has Not Yet Said

The June 2026 release is the technical conclusion of the investigation, not its end. NIST says the team is now writing its final report, which will include the full evidence analysis, test results and computer modeling behind the findings, along with recommendations for changes to standards, codes and practices and any further research needed. Until that report is published, the recommendations are not known, and no one should present a guess about them as fact. Owners, boards and engineers should expect the final report to inform the next round of code and practice changes.

Jonnatan R. Mendez, PE, SI , has more than 20 years of structural engineering, condition assessment and repair experience in South Florida, and he is a Florida Threshold Building Special Inspector. Every milestone inspection we perform is led by a licensed engineer who examines the whole structure the statute covers, including garages, decks and other nonhabitable areas.

When Phase 2 is needed, we measure rather than estimate: sounding, cover and section-loss measurements, and correlation with the original drawings where they exist, so the association can separate cosmetic distress from conditions that affect the structure and plan its repairs and reserves from real quantities. We work with boards and managers across South Florida, including Miami-Dade and Broward buildings subject to both the state milestone law and county recertification. For boards new to these requirements, our plain-English guide to Florida condo inspection law is a good place to start, and when a building element has already failed, our forensic engineering practice investigates the cause.

Common Questions About Florida Building Inspection After Surfside

The Short Version

What Changed in Florida Law

Florida did not wait for the federal findings. Three laws built the current system, and our timeline of Florida's condo safety laws walks through each one in detail. In summary:

What Changed in Inspection Practice

Phase 1 is a visual examination by a licensed engineer or architect of habitable and nonhabitable areas, including the major structural components, with a qualitative assessment of their condition. If it finds substantial structural deterioration, Phase 2 must follow, and it may involve destructive or nondestructive testing. The engineer submits a sealed report with a summary of the material findings, and if proof that repairs have been scheduled or started is not provided in time, the local building official must decide whether the building is unsafe for occupancy. Our guide to Phase 1 and Phase 2 explains each step.

What Boards Still Get Wrong

Most associations now comply with the deadlines. The problems we see are in how the inspection and the repairs are handled, and they repeat from building to building.

Why Garages and Plaza Decks Deserve Attention

NIST located the start of the collapse at slab-column connections in the garage beneath the pool deck, not in the residential tower. That is a finding about one building, and it should not be stretched into claims about others. It does underline, in engineering terms, why the elements under and around a building deserve the same attention as the tower itself.

Garage slabs and plaza or pool decks are often exposed to water from above, depend on waterproofing and drainage that wear out, and are where owners are most likely to add weight over time. Flat slab construction carries load through the connection between slab and column, so cracking, corrosion or leaking around those connections is something an inspector should record and, where it is significant, investigate further. On coastal buildings the corrosion side of that picture is the same one we describe in our guide to concrete spalling and rebar corrosion .

SB 4-D, passed in a May 2022 special session, created the statewide milestone inspection program in Fla. Stat. 553.899 and the structural integrity reserve study requirement for condominium associations.
SB 154 , in 2023, revised the program: it let local enforcement agencies accept earlier inspections that substantially comply, allowed inspections by a team of design professionals with an engineer or architect in responsible charge, required notice to unit owners, and directed the Florida Building Commission to set up a building safety program in the Florida Building Code.
HB 913 , in 2025, applied the milestone and SIRS requirements to buildings three habitable stories or more in height, and required engineers, architects and contractors bidding on milestone inspections or SIRS to disclose in writing any intent to bid on the resulting repair work, with undisclosed conflicts making the contract voidable.

The structural integrity reserve study is the funding side of the same system. It requires associations to plan, and fund, the repair and replacement of the building's structural and life-safety components rather than deferring them indefinitely.

Treating Phase 1 as a formality to be completed as cheaply as possible, rather than as the one time a licensed professional looks at the whole structure.
Limiting access, so garages, plaza and pool decks, mechanical rooms and other nonhabitable areas get less attention than lobbies and hallways, even though the statute covers them.
Adding weight without engineering review: planters, pavers, new pool finishes, rooftop equipment or deck changes that increase load on slabs never designed for it.
Patching and painting over cracks, spalls and rust stains between inspections, which hides the evidence the next inspector needs.
Waiting after a Phase 2 report, when the repair clock and the building official's review have already started.
Losing the building's records. Original drawings, earlier inspection reports and repair documents make every future inspection more accurate.
Hiring on price without asking about conflicts, when HB 913 now requires written disclosure of any intent to bid on the repairs.

The milestone law turned what had been a patchwork of local recertification programs into a statewide requirement. Under Fla. Stat. 553.899 , a covered condominium or cooperative building must have a milestone inspection by December 31 of the year it reaches 30 years from its certificate of occupancy, and every 10 years after, and local agencies may set an earlier first inspection where local conditions warrant it. Miami-Dade and Broward already had their own recertification programs, which continue alongside the state law.

On June 24, 2021, part of Champlain Towers South, a 12-story condominium in Surfside, collapsed, and 98 people lost their lives. In the five years since, the National Institute of Standards and Technology has investigated why, and Florida has rewritten how condominium and cooperative buildings are inspected and funded. The Surfside condo collapse law changes began with SB 4-D in 2022, were revised by SB 154 in 2023, and were revised again by HB 913 in 2025.

This guide sets out what NIST has found so far, what the law now requires, and where boards still run into trouble. It keeps to what NIST and the statutes actually say. The investigation's final report and formal recommendations are still being written, so anything beyond the released findings would be speculation, and this is not a subject for that. For the inspections themselves, see our milestone inspections page.

Severe and widespread deviations in the original structural design from the codes and standards of the time, along with some limitations in those codes and standards.
Deviations in the building's construction from its design drawings.
Loads added to the structure over its lifetime, including pool deck modifications.
Long-term degradation from corrosion.

NIST also listed factors the investigation ruled out as contributors: vibrations from nearby construction; foundation failure, sinkholes or settling; hurricane and storm surge effects; impulsive loads such as a dropped weight or an explosion; and accidental overloads from the roof project underway at the time.

Florida Mold Assessor Licensing: Why It Matters Who Inspects Your Building

Fri, 25 Sep 2026 14:41:55 GMT

What Part XVI Licenses

The definitions in Fla. Stat. 468.8411 set the scope. A mold assessment is a process performed by a mold assessor that includes physical sampling and detailed evaluation of data from a building history and inspection to form an initial hypothesis about the origin, identity, location and extent of mold growth greater than 10 square feet. A mold assessor is anyone who performs or directly supervises that work. Mold remediation is the removal, cleaning, sanitizing, demolition or other treatment of mold or mold-contaminated material over the same 10 square foot threshold.

The Department of Business and Professional Regulation administers the program under Part XVI and Rule 61-31 of the Florida Administrative Code, and its published guidance fills in the practical requirements.

The Assessor Versus Remediator Rule

Section 468.8419 is where the conflict of interest rule sits. A mold assessor may not perform or offer to perform mold remediation on a structure on which the assessor or the assessor's company provided a mold assessment within the last 12 months. The mirror rule bars a remediator from assessing a structure the remediator or the remediator's company remediated within the last 12 months. The department's own guidance quotes both provisions when it explains that a company doing both kinds of work needs both licenses.

The reason is simple. A company that will be paid to remove mold has an incentive to find more of it, and a company that has just removed it has an incentive to find that the work succeeded. Separating the two keeps the scope honest at the start and the clearance honest at the end. The statute has one narrow exception: a certified Division I contractor may assess and offer to remediate, subject to any department rule requiring the contract to tell the homeowner of the right to request competitive bids.

Section 468.8419 goes further than the 12 month rule. It bars an assessor from inspecting for a fee any property in which the assessor or the assessor's company has a financial or transfer interest, and it bars remediators from paying or accepting referral fees from assessors. Violations are crimes, starting as a second degree misdemeanor and rising to a third degree felony for repeat violations.

Mistakes That Make Mold Come Back

How M&P Consulting Engineers Approaches Mold Assessment

Jonnatan R. Mendez, PE, SI , is a licensed Professional Engineer and a licensed mold assessor, so our mold work is led by someone who can evaluate both the growth and the building behind it. We provide mold assessment and related investigative services only and do not perform mold remediation or removal work, which keeps every assessment independent of the remediation that follows.

Our assessments combine mold assessment practice with moisture mapping, thermal imaging where appropriate, and building science, and our reports document conditions, sampling results where taken, the likely moisture source, and a remediation protocol when one is required. When a claim or dispute follows, the same engineer can provide causation opinions and expert testimony . Active leaks and occupied-unit complaints are usually scheduled within a few business days in Miami-Dade, Broward and Palm Beach, including Coral Gables , Doral , Hialeah and Hollywood .

No. Slip resistance is one input. A sound opinion reads it alongside the surface condition, any contaminant, footwear, lighting, and maintenance history.

Common Questions About Florida Mold Assessor Licensing

The Short Version

Titles, Exemptions and What They Mean for You

The statute also protects the title. A person may not call himself or herself a licensed, certified, registered or professional mold assessor, or simply a mold assessor, without complying with Part XVI. That makes the title on a proposal or report a meaningful claim that can be checked.

Some licensed professionals are exempt when they work within the scope of their own licenses. The department explains that Section 468.841 exempts people acting within the authorized scope of practice of another license, but that anyone relying on the exemption may not hold themselves out for hire as a licensed mold assessor or remediator. In practice, a report that calls itself a mold assessment should come from someone whose mold assessor license you can look up.

What a Mold Assessment Should Include

A review of the leak and moisture history, earlier repairs, reported events, photographs and any construction documents.
A field assessment with visual observation, moisture measurements, relative humidity readings, thermal imaging where appropriate, and sampling when the conditions warrant it.
An evaluation of the likely moisture source and migration path, and the apparent extent of affected materials, including concealed conditions that need selective investigation.
A written remediation protocol that defines the affected areas, containment, removal and cleaning procedures, and the criteria for clearing the work.
Post-remediation verification after the work is done and before walls, ceilings or floors are closed up again.

What a Professional Engineer Adds

Mold is almost always a symptom. It grows where water has been, and in South Florida buildings that water usually comes through a roof, a window, a stucco wall, a slab, a plumbing line or an air conditioning system. If the remediation removes the mold but nobody finds and fixes the source, the growth comes back. That is where engineering matters. A professional engineer who is also a licensed mold assessor can trace the moisture through the building envelope, identify the construction or maintenance condition behind it, and specify the repair.

The engineering also matters when someone has to pay. Insurance claims and disputes turn on causation: whether water damage came from a storm, a construction defect, a plumbing failure or long-term deterioration. That is the same kind of analysis our forensic engineering practice performs on hurricane damage , and it is what an adjuster, a condominium board or opposing counsel needs to see in the report. Long-term water intrusion can also affect the structure itself, from rotted framing to corroding reinforcement, which is why moisture damage is often first found during milestone inspections .

Hiring for a Mold Assessment in Miami

Before you hire anyone, a few questions will tell you whether you are getting an independent assessment. The answers should be easy to give.

Sampling the air without looking for the water, which confirms mold is present but not why.
Starting remediation with no written protocol, so there is no agreed scope and no clear standard for clearance.
Skipping post-remediation verification and closing walls over materials that are still wet or contaminated.
Repairing the drywall but not the roof, window, stucco or plumbing condition that caused it.

The fee owner, or the contractor with the owner's written authorization, signs a written contract with the private provider or the provider's firm.
The building official is notified in writing, at the time of permit application, of the services the private provider will perform, with each provider's license number and qualifications and, if the official requires it, a certificate of insurance.
The private provider reviews the plans for compliance with the applicable codes and signs an affidavit, under oath, that the provider reviewed them, holds the appropriate license, and found that they comply.
The building official has 20 business days after receiving the application and affidavit, or 5 business days for a single-trade review on a one or two family dwelling, to issue the permit or give written notice of the specific plan features that do not comply, citing code chapters and sections.
If the private provider is a licensed engineer or architect who seals the affidavit, that period is 10 business days, and a notice must state with specificity the deficiencies, the reasons the application failed, and the codes violated.
If no deficiency notice arrives in time, the application is deemed approved as a matter of law and the permit must be issued the next business day. After revisions, the official has the remaining time plus 5 business days, and later reviews are limited to the deficiencies already cited.

The license sets a minimum. A useful assessment goes beyond counting spores and tells you what to do next. A complete one usually covers these steps.

Florida licenses the people who assess and remediate mold. Under Part XVI of Chapter 468 of the Florida Statutes, anyone who performs a mold assessment or mold remediation involving more than 10 square feet of growth must hold an individual license from the Department of Business and Professional Regulation. The same law keeps the two jobs apart: a licensed assessor may not remediate a structure the assessor or the assessor's company assessed within the last 12 months, and a remediator may not assess a structure it remediated in that time.

That separation is the most important thing to understand before you hire anyone for a mold assessment in Miami . The person who tells you how much mold there is, where it is, and what has to be removed should not be the person who gets paid to remove it. The rest of this guide explains what the license covers, how the conflict of interest rule works, and what a professional engineer adds when the real question is where the water came from.

Only individuals are licensed. The department does not license mold assessment or remediation businesses, so the license belongs to the person who does the work.
Applicants need either a two-year degree in a related field such as microbiology, engineering, architecture or industrial hygiene with a year of field experience, or a high school diploma with four years of documented experience, plus documented training in water, mold and respiratory protection.
Applicants must pass a state-approved examination and a criminal background check.
A mold assessor must carry general liability and errors and omissions coverage of at least $1,000,000, either personally or as a named individual on the company's policy.
Licensees renew every two years and complete 14 hours of continuing education in mold-related subjects for each renewal.

What is your Florida mold assessor license number? Check it on the state's public licensee search before the visit.
Does your company, or a company you are connected with, perform mold remediation, and would it bid on this job?
Will the report identify the moisture source, or only the mold?
Will you write the remediation protocol, and will you perform the post-remediation verification?
What insurance do you carry, and are you named on the policy?

Chapter 471 and the PE Seal: What 'Signed and Sealed' Means and Why Florida Requires It

Fri, 25 Sep 2026 14:10:46 GMT

What Chapter 471 Requires

Fla. Stat. 471.025 is the seal statute. It requires each licensed engineer to have a seal and to sign, date and seal all final drawings, specifications, plans, reports and documents the engineer prepares or issues that are filed for public record, and all final documents provided to the owner or the owner's representative. Documents may be transmitted, signed, dated and sealed electronically under Florida's electronic signature law.

The same section sets three limits that matter to anyone relying on a sealed document.

What the Seal Means

The Florida Board of Professional Engineers explains the purpose plainly . By signing, dating and sealing a document, an engineer verifies its authenticity and accepts responsibility for its accuracy and legitimacy. The seal lets the agency reviewing it know who prepared it and whom to contact with comments or questions, and it indicates that the document is final.

The board's rules add two important conditions. Under Rule 61G15-23.001, an engineer may only sign, date and seal a document if the engineer was in responsible charge of its preparation and has expertise in the engineering discipline used to produce it. The same rule presumes that sealed documents comply with the codes and standards in effect at the time of sealing, unless the engineer indicates on the documents that another edition was intended. The seal is tied to a specific person, a specific discipline and a specific point in time.

Why It Matters on Real Projects

Mistakes That Undermine a Seal

Most seal problems are avoidable, and several of them are violations rather than mere errors. These are the ones owners and contractors should watch for.

No. Slip resistance is one input. A sound opinion reads it alongside the surface condition, any contaminant, footwear, lighting, and maintenance history.

Sealed documents run through almost every stage of a Florida building project. Permit portals in South Florida require plans to be digitally signed and sealed, which is why a structural change as ordinary as removing a load-bearing wall needs sealed drawings. The High-Velocity Hurricane Zone relies on sealed drawings to carry the design pressures that product approvals are checked against, and flood zone renovations need sealed foundation plans when they cross the substantial improvement threshold.

The seal carries weight in review and inspection too. When a private provider who is a licensed engineer seals the plan review affidavit under Fla. Stat. 553.791, the building official has 10 business days, rather than 20, to act. Milestone inspection reports are submitted as sealed copies, and threshold inspection reports are signed and sealed throughout a repair. In a dispute, the seal identifies the engineer whose work will be examined against the standard of care .

Common Questions About the Florida PE Seal

The Short Version

Three Ways to Sign and Seal

Florida recognizes physical, digital and electronic signing and sealing, each with its own procedure under Chapter 61G15-23 of the Florida Administrative Code. Which one an engineer uses usually depends on how the receiving agency wants the documents filed.

Digital Signing and Sealing

Electronic Signing and Sealing

What Must Be Sealed and What Should Not Be

The requirement covers final documents. Final plans and prints, specifications, calculations and engineering reports that are filed for public record or provided to the owner must be sealed. The rules also set out what those documents must show, and the most common requirements are these.

How to Check a Seal

Anyone can check a Florida engineer's license, and anyone relying on sealed documents should. The state's Department of Business and Professional Regulation runs the public licensee search that FBPE links to, and it shows whether a license is current. A basic check takes a few minutes.

Physical Signing and Sealing

The engineer signs each sheet by hand and applies a wet, embossed or digitally created seal that partially overlaps the signature without making it illegible. The seal must be at least 1 7/8 inches in diameter. A scanned, facsimile, digitally created or copied image of the signature may not be used, and FBPE is explicit that scanned or electronic copies of physically sealed documents are not considered signed and sealed.

On physically sealed plans, every sheet is signed, dated and sealed by the engineer in responsible charge.
Each sheet carries a title block with the engineer's printed name, address and license number, and the name and address of the engineering business where applicable.
Specifications and calculations can use a sealed index sheet showing which sections each engineer was in responsible charge of.
The date of sealing appears next to the seal.

A digital signature must be unique to the engineer, issued by a third-party certification authority, capable of verification, under the engineer's sole control, and linked to the document so that any change invalidates it. FBPE notes that the self-authenticated signature option built into common PDF software does not qualify on its own. The signed file carries required text stating that it has been digitally signed and sealed and that the signature must be verified on any electronic copies.

The electronic method runs the document files through a secure hash standard generator, which produces an authentication code for each file. The engineer lists those codes on a signature report, then prints, hand signs, dates and seals the report and sends it with the files. Printed copies of electronically sealed documents are not considered signed and sealed, and simply locking or encrypting a file is not a signature.

A Florida professional engineer seal on a drawing, report or set of calculations is a legal statement, not a decoration. Under Chapter 471 of the Florida Statutes, every final engineering document filed for public record or delivered to an owner must be signed, dated and sealed by the licensed engineer who prepared it, and that signature, date and seal are the evidence that the document is authentic. By sealing it, the engineer takes personal professional responsibility for its content.

For owners, contractors, lenders and building departments, the seal answers three questions at once: who prepared the document, whether that person is licensed to do so, and whether the document is final. Knowing how the seal works, and how to check one, protects everyone who relies on the engineering, which is why every structural design and analysis package we issue is sealed by the engineer in responsible charge.

It is unlawful to seal or digitally sign any document after the engineer's license has expired or been revoked or suspended, unless the license has been reinstated.
An engineer may not seal any document depicting work the engineer is not licensed to perform or that is beyond the engineer's profession or specialty.
A successor engineer who reuses documents previously sealed by another engineer must be able to independently re-create the original work, and by sealing them assumes full professional and legal responsibility for them.

Chapter 471 also lists grounds for discipline, including affixing or permitting to be affixed a seal, name or digital signature to documents that were not prepared by the engineer or under the engineer's responsible supervision, direction or control.

Documents that are not final should not be sealed unless their limits are marked on them, with words such as "preliminary," "for review only" or "not for construction." A sealed drawing with no such note tells the reader it is final.

Look up the engineer by name or license number and confirm the license is active and was active on the date of sealing.
Confirm the name and license number in the title block match the seal and the license record.
For a digitally sealed PDF, open the signature panel and confirm the signature is valid and the document has not changed since it was signed.
For electronically sealed files, confirm there is a signed and sealed signature report whose authentication codes match the files.
Treat a scanned copy of a hand-sealed set, or a printout of an electronically sealed file, as a copy, not as sealed documents.

Accepting a scanned image of a seal and signature as if it were a sealed document.
Reusing drawings sealed by another engineer for a new permit or revision without a successor engineer taking responsibility for them.
Sealing work prepared by someone outside the engineer's responsible supervision, sometimes called plan stamping.
Relying on a document sealed while the engineer's license was lapsed or suspended.
Relying on a seal outside the engineer's discipline, such as structural drawings sealed by an engineer with no structural expertise.
Editing a digitally sealed PDF after the fact, which invalidates the signature.

How M&P Consulting Engineers Seals Its Work

Every final deliverable we issue, whether structural drawings, calculations, inspection reports or forensic reports , is signed, dated and sealed by the Professional Engineer who was in responsible charge of it. Each engagement has direct involvement from the principal, from the first evaluation through the sealed document, so the name on the seal is the person who did the engineering.

Structural Plans Review for Municipalities: How Independent Peer Review Works Under the Florida Building Code

Fri, 25 Sep 2026 13:17:13 GMT

Structural plans review in Florida happens along three different routes, and the rules depend on which one is in use. A building department reviews plans itself, with its own staff or with outside reviewers it contracts. An owner or contractor can hire a private provider under Fla. Stat. 553.791 to review the plans instead, with the building department keeping authority to issue the permit. And an owner, developer or lender can commission an independent peer review before the plans are ever submitted.

The first two are code compliance reviews on behalf of the permitting process, and Florida law controls who may perform them, how fast the building official must respond, and what the reviewer certifies. The third is a check on the engineering itself. For municipalities managing permit backlogs and developers managing schedules, knowing the difference decides how a review is contracted, documented and relied on. Independent structural plans review of that kind is what this guide explains.

Three Kinds of Structural Review

The three routes answer different questions for different clients. Each has its own paperwork, its own liability, and its own limits on who can do the work.

Who Can Review Plans in Florida

Part XII of Chapter 468 of the Florida Statutes licenses building code administrators, plans examiners and inspectors. It defines a plans examiner as a person qualified to determine that plans submitted for permits comply with the applicable building codes, and it is the licensing framework for the people who review plans on a building department's behalf.

Two provisions matter most for outside reviewers. Fla. Stat. 468.617 allows local governments, school boards, state universities and state agencies to contract with persons certified under Part XII to perform plan reviews and inspections, and separately lets counties and municipalities contract with any person or entity for building code services regulated under that part. The same section says an individual or entity may not examine plans on projects it designed or permitted.

Private provider review follows its own definition. Under Fla. Stat. 553.791 , a private provider is a person licensed as a building code administrator under Part XII, as an engineer under Chapter 471, or as an architect under Chapter 481. A private provider may only perform services within the disciplines covered by that person's license, and may not provide them on any building the provider or the provider's firm designed or constructed. A structural engineer acting as a private provider therefore reviews the structural discipline, not the whole permit set.

Mistakes That Slow Permits Down

How M&P Consulting Engineers Approaches Plans Review

Every review we perform is done by a licensed Professional Engineer and returned as an organized comment letter that cites the specific Florida Building Code, ASCE 7, ACI 318, AISC or TMS provision behind every item. We confirm the governing code edition and jurisdiction-specific amendments first, review drawings, details and calculations together, separate true code deficiencies from clarifications, and close each review in writing for the permit file. Most single-building first-pass reviews are returned in 48 to 72 hours.

Jonnatan R. Mendez, PE, SI , brings more than 20 years of structural design and qualified plans examiner experience under the Florida Building Code, and he is a Florida Threshold Building Special Inspector. That combination means we have sat on both sides of the comment letter. Our structural design and analysis work keeps the review grounded in what is practical to build, and our expert witness practice gives us a clear view of how design documents are judged when something goes wrong.

We provide plans review and peer review for building departments, developers and design teams across South Florida, including Doral , Hialeah and Pompano Beach , and we never perform both on the same project for opposing parties.

Common Questions About Structural Plans Review in Florida

The Short Version

How Private Provider Plan Review Works

Section 553.791 sets out the private provider process in detail, including deadlines that bind the building official. The steps below follow the statute.

What Municipalities Should Know

Private provider review works differently, because the department does not choose the reviewer. The building official may not replicate the private provider's plan review except as the statute allows, may not adopt rules or qualifications more stringent than the statute, and must post its audit procedures publicly before auditing. The official keeps the authority to deny a permit that does not comply and to issue a stop-work order for a condition that is an immediate threat to public safety. Section 553.791 also lets counties, municipalities, school districts and special districts use private providers on their own public buildings and works.

What a Structural Review Checks

Whichever route is in use, a structural review covers the same technical ground. In South Florida it usually includes these items.

How Peer Review Differs

A peer review is commissioned by the owner, developer, lender or design team, not by the authority having jurisdiction, and it happens before submittal. Its purpose is to find load path gaps, missing details and calculation errors while they are still inexpensive to fix, and to reduce the number of review cycles at the building department. It is common on large or complex projects, on projects where a lender wants independent assurance, and on existing buildings where a repair or alteration depends on assumptions about the original structure, such as a load-bearing wall removal .

Peer review does not carry the legal effect of a plan review. It produces a comment letter for the design engineer, who remains responsible for the design and seals the drawings. The reviewer must be independent of the design, and a firm that performs both plan review and peer review should never do so on the same project for opposing parties.

Using a reviewer connected to the design, which both statutes prohibit for their respective routes.
Comment letters without code citations, which lead to arguments instead of corrections.
No written back-check, so it is unclear which comments were closed and which remain.
Deferred submittals left to the end, when truss or railing designs turn out not to match the permit drawings.
Reviewing to the wrong code edition around a code change, such as the 9th Edition of the Florida Building Code taking effect on December 31, 2026.
For private provider review, an incomplete notice to the building official, missing license numbers or insurance, which can stop the clock before it starts.

The fee owner, or the contractor with the owner's written authorization, signs a written contract with the private provider or the provider's firm.
The building official is notified in writing, at the time of permit application, of the services the private provider will perform, with each provider's license number and qualifications and, if the official requires it, a certificate of insurance.
The private provider reviews the plans for compliance with the applicable codes and signs an affidavit, under oath, that the provider reviewed them, holds the appropriate license, and found that they comply.
The building official has 20 business days after receiving the application and affidavit, or 5 business days for a single-trade review on a one or two family dwelling, to issue the permit or give written notice of the specific plan features that do not comply, citing code chapters and sections.
If the private provider is a licensed engineer or architect who seals the affidavit, that period is 10 business days, and a notice must state with specificity the deficiencies, the reasons the application failed, and the codes violated.
If no deficiency notice arrives in time, the application is deemed approved as a matter of law and the permit must be issued the next business day. After revisions, the official has the remaining time plus 5 business days, and later reviews are limited to the deficiencies already cited.

The statute also requires the local jurisdiction to reduce the permit fee by the cost it saves, sets minimum professional liability insurance for private providers of $1 million per occurrence and $2 million aggregate on projects of $5 million or less, and $2 million and $4 million above that, and limits building department audits of the same provider to four a year unless there is an immediate threat to public safety.

The governing code edition, occupancy, risk category and any local technical amendments.
Gravity and lateral load paths, including diaphragms, shear walls, frames and continuity to the foundation.
Wind design: design wind speed, exposure, enclosure classification, uplift, and in Miami-Dade and Broward the High-Velocity Hurricane Zone provisions and product approval coverage.
Foundations, including soil bearing assumptions and, in flood hazard areas, flood loads.
Details and connections, checked against the calculations rather than on their own.
Deferred submittals such as trusses, cold-formed framing, railings and canopies, checked against the permit documents.
For threshold buildings , the structural inspection plan and the special inspection requirements.

Building department plan review. The authority having jurisdiction checks the permit documents for compliance with the Florida Building Code, using its own plans examiners or reviewers it contracts to supplement them.
Private provider plan review. Under Fla. Stat. 553.791, the fee owner, or the contractor with the owner's written authorization, hires a licensed private provider to review the plans and certify compliance by affidavit, and the building official then issues the permit or cites specific deficiencies.
Peer review. An owner, developer, lender or design team commissions an independent engineer to test the design for completeness, constructibility and code compliance before submittal. It does not replace either of the other reviews.

For a building department, outside structural review is a way to handle peak volume and specialty projects without adding permanent staff. The contract route under Section 468.617 lets the department keep review in its own process, with outside reviewers issuing comments on its behalf, while the conflict rule keeps them off any project they designed or permitted.

In both routes, the value of the review depends on how specific it is. A comment that cites the exact provision of the Florida Building Code, ASCE 7 or ACI 318 behind each deficiency gives the design engineer something to correct and gives the building official a record that holds up on appeal.

Concrete Spalling, Rebar Corrosion and Balcony Failures in Coastal Florida Buildings: What Inspectors Look For

Fri, 25 Sep 2026 12:41:10 GMT

Concrete spalling on a coastal Florida building is usually the visible end of a longer process. Salt carried in sea air and wind-driven rain works its way through the concrete to the reinforcing steel, the steel corrodes, and the rust takes up more room than the steel it replaced. That expansion cracks the concrete from the inside, and eventually pieces break away. Balconies show it first, because they are thin, exposed on several sides, and carry railings anchored into their edges.

A concrete spalling balcony inspection is about telling surface blemishes apart from deterioration that affects how the structure carries load. Florida's milestone inspection law draws that same line, and it decides whether a building needs a Phase 2 inspection. This guide walks through what inspectors look for, what they test, and how repairs are designed, using photographs from our own coastal projects in Palm Beach Shores and Pompano Beach. It is the practical side of the milestone inspections we perform on condominium and cooperative buildings.

How Rebar Corrosion Turns Into Spalling

New concrete is highly alkaline, and that alkalinity forms a protective film on the surface of the reinforcing steel. Two things break it down over time. Chlorides from salt spray and wind-driven rain migrate inward through the concrete cover, and carbon dioxide from the air slowly lowers the alkalinity from the surface in, a process called carbonation. Once either reaches the steel in enough concentration, and there is moisture and oxygen present, the bar starts to corrode.

Corrosion products occupy several times the volume of the original steel. As they build up, they push outward against the concrete, first causing cracks that run along the line of the bar, then a delamination, a hidden plane of separation just above the steel, and finally a spall where the concrete breaks free. By the time a spall appears, the bar behind it has usually been corroding for years, and it may have lost part of its cross-section, which reduces its capacity.

Why Balconies Fail First

Balcony slabs are thin, so there is less concrete cover between the weather and the steel than in most other parts of the building.
They are exposed on the top, the soffit and the edge, so salt and water reach the steel from more than one side.
Railing posts are often set into pockets at the slab edge, and water that gets into those pockets sits directly against the steel.
Failed waterproofing, tile laid without slope, and blocked drains leave water standing on the deck.
Cantilevered balconies depend entirely on the top reinforcement near the building face, the steel that is hardest to see and most exposed to water entering from above.

What Boards and Owners Should Do

For a condominium or cooperative board, the steps are largely set by the milestone program, and the order matters. This is how it usually runs when a coastal building shows spalling.

Mistakes That Let Deterioration Continue

No. Slip resistance is one input. A sound opinion reads it alongside the surface condition, any contaminant, footwear, lighting, and maintenance history.

The photographs in this guide from Pompano Beach show that project before and during repair.

Common Questions About Concrete Spalling and Balcony Inspections

The Short Version

What Inspectors Look For

A visual inspection is the first step, and on a coastal building it covers every balcony, slab edge, walkway, column and railing that can be reached. On the beachfront building we evaluated in Palm Beach Shores , decades of salt-laden air and wind-driven rain had produced deterioration at slab edges, railing embedments, columns and other reinforced concrete components. These are the signs an inspector records.

Surface Distress vs. Substantial Structural Deterioration

Have the Phase 1 inspection cover every balcony and slab edge that can be reached, and ask the engineer to note where access was limited.
If Phase 2 is required, approve the testing promptly, because the report and the repair scope depend on it.
Close balconies with loose concrete, rocking railings or visible sagging until the engineer has looked at them.
Use the Phase 2 findings to set the repair scope, obtain engineered repair drawings, and permit the work.
Schedule or start repairs within the timeframe the statute sets , since the local building official must review whether the building is unsafe for occupancy if proof of repairs is not submitted.
Keep the reports, the repair documents and the inspection records together; they are the building's record for the next milestone cycle.

Not every crack or stain is a structural problem, and Florida law says so. Under Fla. Stat. 553.899 , substantial structural deterioration means substantial structural distress or weakness that negatively affects a building's general structural condition and integrity. The statute excludes surface imperfections such as cracks, distortion, sagging, deflections, misalignment, signs of leakage or peeling finishes, unless the engineer or architect performing the inspection determines they are a sign of substantial structural deterioration.

That judgment is the inspector's, and it has consequences. Phase 1 of a milestone inspection is a visual examination with a qualitative assessment. If it finds no signs of substantial structural deterioration, Phase 2 is not required. If it does, Phase 2 must be performed, and it may involve destructive or nondestructive testing at the inspector's direction. A corrosion stain at one balcony may be a maintenance item; the same stain at a line of slab edges with delaminated concrete behind it points to a condition that affects the structure.

Testing and Measuring

Phase 2 replaces visual judgment with measurement. On the Palm Beach Shores building, we evaluated the structure floor by floor, performing concrete sounding, documenting areas of distress, and measuring concrete cover and reinforcement section loss at representative locations. The findings were then compared with the original structural drawings, so each condition could be placed within the structural system and its significance judged. The methods commonly used include these.

How Repairs Are Designed Under ACI 562

Repairs to existing concrete are governed by engineering standards written for that purpose. ACI 562 , the American Concrete Institute's code for the assessment, repair and rehabilitation of existing concrete structures, sets minimum requirements for assessing damage and deterioration and designing the repair. It can supplement an existing building code or stand alone, and it is written for use by a licensed design professional. Where a repair adds new structural concrete or changes how a member carries load, the design also draws on ACI 318, the building code requirements for structural concrete.

A typical balcony or slab edge repair follows a well-established sequence. The area is shored if the repair will reduce its capacity, the deteriorated concrete is removed to sound material and far enough behind the bars to expose their full circumference, the steel is cleaned, and bars with too much section loss are supplemented or replaced as the engineer specifies. The steel is coated, the repair is formed and filled with a compatible repair material, and the surface is waterproofed so the cycle does not start again.

Rust staining bleeding from cracks, joints or the surface of the concrete.
Cracks that run straight and parallel to where reinforcing bars would be, often along slab edges and the corners of columns.
A hollow sound when the concrete is tapped with a hammer or dragged with a chain, which indicates a delamination below the surface.
Bulging stucco or coatings, and earlier patches that have cracked around their edges or popped loose.
Exposed reinforcing steel, and steel with visible loss of section.
Loose or rocking railing posts, and cracked concrete around the post pockets.
Sagging at the outer edge of a cantilevered balcony, standing water, and stains on the soffit below.

Sounding and delamination mapping, marking every hollow area on slabs, edges, columns and soffits so the repair quantities are measured rather than guessed.
Cover surveys with a covermeter or ground-penetrating radar, which show how deep the steel sits and where cover is thin.
Exploratory openings at representative locations to expose the bars and measure the remaining section with calipers.
Chloride testing of concrete samples taken at different depths, and carbonation testing, which show how far the corrosion front has advanced.
Cores for compressive strength where the capacity of the existing concrete matters to the repair design.
Review of the original drawings to confirm bar sizes, spacing and the structural role of each element that is deteriorating.

The result separates localized surface deterioration from conditions that affect the reinforcement and the load-carrying performance of the building, which is exactly the question the Phase 2 report has to answer. It also produces the repair scope and quantities the association will budget from, and that feeds into its structural integrity reserve study .

The Palm Beach Shores association had completed localized surface and finish repairs over the years, but no one had evaluated the structure beneath them. That pattern is common, and it is behind most of these mistakes.

atching over corroded steel without removing concrete behind the bars, which traps the corrosion and often creates new spalls around the edge of the patch.
Painting or coating over rust stains and cracks, which hides the evidence the next inspector needs.
Reinstalling railings into deteriorated slab edges instead of repairing the embedment first.
Repairing concrete without fixing the waterproofing, slope or drainage that let the water in.
Removing concrete from a balcony or edge without shoring it first.
Leaving no record of what was repaired, where, and with what, so the next inspection starts from nothing.

How M&P Consulting Engineers Approaches Coastal Concrete

Jonnatan R. Mendez, PE, SI , has more than 20 years of structural engineering, condition assessment and repair work in South Florida, including concrete, masonry and post-tensioned systems. He is a Florida Threshold Building Special Inspector, which means we can take a building from the first inspection through the repair design to inspection of the work in place.

Our approach is the one described above: measure what is there, correlate it with how the building was designed, and separate what is cosmetic from what affects the structure before anyone prices a repair. We do that for milestone and recertification inspections , for boards planning restoration, and in Broward coastal cities such as Pompano Beach , where chloride-driven corrosion and balcony repairs make up much of the work.

Thu, 24 Sep 2026 19:03:31 GMT

The FEMA 50 percent rule decides when an older building in a flood zone has to be brought up to current flood standards. If the cost of a renovation, addition or repair equals or exceeds 50 percent of the market value of the structure, the project is a substantial improvement, and the whole building then has to meet the rules for new construction, which in an AE zone means a lowest floor at or above the base flood elevation plus freeboard. The same threshold applies after a storm or fire, when the cost to restore a damaged building reaches half its value, which is called substantial damage.

In Miami-Dade the rule is stricter than the federal minimum. The county adds up improvements over time rather than one permit at a time, and it requires at least one foot of freeboard above the base flood elevation. For an owner of an older home built at grade in an AE zone, crossing the line can turn a planned renovation into a rebuild, so the time to understand it is before the scope is fixed. The structural design and analysis questions it raises, from foundations to elevation, are where an engineer comes in.

What the 50 Percent Rule Says

The rule comes from the National Flood Insurance Program regulations. Under 44 CFR 59.1 , a substantial improvement is any reconstruction, rehabilitation, addition or other improvement of a structure whose cost equals or exceeds 50 percent of the structure's market value before construction starts. Substantial damage is damage of any origin where the cost of restoring the building to its condition before the damage would equal or exceed 50 percent of its market value before the damage. A substantially damaged building counts as substantially improved regardless of the repair work actually done.

Two kinds of work are excluded. Improvements required to correct existing health, sanitary or safety code violations that are solely necessary to assure safe living conditions do not count, and neither does an alteration to a historic structure that will not stop it from keeping its historic designation. Everything else in the project is on the table, including work that has nothing to do with flooding.

Communities enforce the rule because it is a condition of their participation in the flood insurance program. Under 44 CFR 60.3 , communities must require new construction and substantial improvements of residential buildings in Zones A1 to 30, AE and AH to have the lowest floor, including any basement, elevated to or above the base flood level. That federal baseline is what Miami-Dade builds on.

How the 50 Percent Is Calculated

Market Value of the Structure

The denominator is the market value of the building alone, not the land it sits on. In South Florida that distinction matters, because land often makes up most of a property's value, and using the total sale price or total assessed value overstates what the building is worth. Miami-Dade's ordinance uses the appraised value of the structure before the start of the initial repair or improvement, or, for damage, its value just before the damage occurred. An owner who thinks the default figure is too low can usually submit an independent appraisal of the structure for the building department to consider.

How the Determination Works

Mistakes That Trigger the Rule by Surprise

Most substantial improvement problems come from how the project is scoped and documented rather than from the rule itself. These are the ones that catch owners most often.

The building department makes the substantial improvement determination as part of the permit review, but the owner and design team supply most of what it relies on. On a well-run project the sequence looks like this.

Common Questions About the FEMA 50 Percent Rule

The Short Version

Cost of the Improvement

The numerator is the full cost of the work, priced at market rates, whether the owner hires a contractor or does part of it themselves. FEMA's guidance for floodplain managers stresses that after damage, the cost to repair must be calculated for full repair to the building's condition before the damage, even if the owner chooses to do less, and must include any improvements the owner adds at the same time. In general, the costs that count and the costs that do not look like this.

Miami-Dade's Stricter Version

Chapter 11C of the Code of Miami-Dade County , the county's floodplain regulations, was comprehensively revised in 2022, through Ordinance Nos. 22-141 and 22-142, partly to earn a better Community Rating System class and lower flood insurance premiums. It applies in unincorporated Miami-Dade and in the parts of incorporated areas where the county has jurisdiction over building permits. Three of its provisions go further than the federal minimum.

Splitting one renovation into several small permits, which the county adds back together within the accumulation period.
Leaving items out of the estimate, only for the building department or a later inspection to add them back.
Using the total property value, land included, as the market value of the structure.
Adding scope during construction without reporting it, which can push an approved project over the line after the fact.
Assuming storm repairs are exempt, when a hurricane or fire that causes substantial damage triggers the same requirements.
Designing to a preliminary flood map, which Miami-Dade's ordinance says may not be relied on in place of the effective map.

Cumulative counting. Any combination of repairs, reconstruction, alterations or improvements taking place within six months counts together, and within the coastal building zone defined in Fla. Stat. 161.54, a band along the coast that takes in much of the barrier islands, the period is five years.
Freeboard. The lowest floor of a residential building in a special flood hazard area, including attached garages and enclosures, must be elevated to the base flood elevation plus freeboard, defined as the stricter of one foot or the freeboard the Florida Building Code requires. Machinery and equipment must be elevated to the same level.
No floodproofing for homes. Residential buildings cannot meet the requirement with dry or wet floodproofing, although attached garages and storage enclosures may be wet floodproofed. Nonresidential buildings may be dry floodproofed to the same level instead.

Cities that run their own building departments are separate participants in the flood insurance program and adopt their own floodplain ordinances. A renovation in Homestead , Coral Gables or another municipality follows that city's version, which may set a different accumulation period. The first question for any project is which ordinance applies to the address.

What a Substantial Improvement Requires

Once a project is a substantial improvement, the building as a whole has to comply, not only the new work. Section 1612 of the Florida Building Code, Building governs flood loads and flood-resistant construction in flood hazard areas, and it works together with the county's floodplain rules. In an AE zone, compliance usually comes down to the following.

Why It Matters for AE Zone Renovations

Many older homes in Miami-Dade's AE zones were built with a slab on grade before flood maps existed, and their lowest floors sit below today's base flood elevation. For those homes the 50 percent line is easier to cross than owners expect. A new roof, impact windows, a kitchen and two bathrooms can add up to half the value of a modest older house, especially once the land is excluded from the value.

f the project crosses the line, raising a concrete block house on a slab is technically possible but rarely practical, and the realistic options become reducing or phasing the scope, elevating the building, or demolishing and rebuilding to current standards. Phasing only works within the county's rules, because improvements inside the six month or five year window are added together. That is why the scope, the estimate and the market value should be settled before design goes too far. It applies to the smaller jobs that often start a renovation, too; even removing a wall is part of the total cost.

Coastal condominiums face a version of the same question. Large concrete restoration projects that follow a milestone inspection in buildings in Miami Beach or Key Biscayne are repairs, and repair costs count toward the threshold under the county's definition. Associations planning major work should confirm early how their city counts it.

Confirm the flood zone and base flood elevation for the address from the effective flood map, not a preliminary one, and find or order an elevation certificate showing the current lowest floor.
Establish the market value of the structure, using the building department's default method or an independent appraisal of the building alone.
Prepare a complete cost estimate for the whole scope, including work planned in later phases inside the accumulation period.
Submit the estimate and value for the building department's review, and adjust the scope if the result is close to the line.
If the project is a substantial improvement, design the building to comply, including the foundation, elevation and flood openings, and have the foundation plans sealed.
Submit the certified lowest floor elevation at the required inspection stage and keep the scope matched to what was approved.

Counted: structural work, roofing, windows and doors, interior finishes, cabinets and built-in fixtures, plumbing, electrical and mechanical systems, and the contractor's labor, overhead and profit.
Usually not counted: plans and specifications, surveys, permit fees, debris removal and cleanup, and items that are not permanently attached to the building, such as furniture and freestanding appliances.

The building department applies its own worksheet, so the list above is a guide to what to expect rather than a substitute for asking. The safe assumption is that anything built into the house will be counted.

The lowest floor elevated to the base flood elevation plus freeboard, with mechanical, electrical and plumbing equipment at or above the same level.
Flood-resistant materials below that elevation, and a building anchored against flotation, collapse and lateral movement.
Any enclosed area below an elevated floor limited to parking, building access or storage, with at least two flood openings totalling one square inch of net area for each square foot of enclosed area, the bottom of each no more than one foot above grade.
Foundation plans signed and sealed by a Florida licensed engineer or architect, and a certified lowest floor elevation from a surveyor or engineer submitted before the tie-beam inspection.

In coastal high hazard areas, the VE zones along the open coast, the requirements are stricter again. Buildings are elevated on piles or columns, and the space below can only be enclosed with breakaway walls, lattice or screening designed to fail under wave action without damaging the structure. Under Miami-Dade's rules, an area enclosed by unreinforced block larger than 299 square feet is treated as the lowest floor for flood insurance purposes.

His background covers concrete, masonry, steel, aluminum and wood construction, and repair, retrofit and rehabilitation design, which is the work a flood zone renovation usually involves.

For owners in flood zones, we evaluate the existing structure and foundation, help define a repair or renovation scope the owner can defend, and when a project is a substantial improvement, design the structural work compliance requires and seal the foundation plans the county asks for.

Do I Need a Structural Engineer to Remove a Wall in Miami-Dade? Permits, Load-Bearing Walls and Sealed Drawings

Thu, 24 Sep 2026 18:23:12 GMT

If the wall carries weight from the roof or a floor above, or helps the house resist hurricane wind, then yes: in Miami-Dade you need a structural engineer to remove it. The building department will expect a permit, and for a structural change it will expect signed and sealed drawings showing what replaces the wall, usually a beam, the posts or columns that hold the beam up, and the footings and connections under and around them. If the wall carries nothing, it may be a simple interior alteration, but it still usually needs a permit, and the only reliable way to know which kind of wall you have is to have someone qualified look at the structure.

The engineer's job is to trace where the load goes today, design a new path for it once the wall is gone, and put that design on paper the building department can approve and the inspector can check. Done early, it is one of the smaller costs of an open-plan remodel. Done late, after a wall is already down, it becomes an emergency. The structural design and analysis behind a wall removal is ordinary work for a structural engineer, and the steps below explain what it involves.

Load-Bearing, Non-Load-Bearing and Shear Walls

Walls in a house do one of three jobs. A non-load-bearing wall, often called a partition, only divides space and carries its own weight. A load-bearing wall supports the roof framing, a ceiling, or a floor above, and passes that weight down to the foundation. A shear wall resists sideways force, mainly wind, and keeps the house from racking. Some walls do more than one of these jobs, and a wall that looks like a partition from the room side can still be part of the structure.

There are clues that point one way or the other, and they are worth knowing before you call anyone. None of them is proof on its own, and each has exceptions.

Why South Florida Homes Are Different

Block Walls, Tie Beams and Hurricane Straps

Most houses in Miami-Dade are built with concrete block walls topped by a reinforced concrete tie beam, with roof trusses or rafters strapped to that beam. Interior walls may be wood framed or block, and in some homes interior block walls were built to support the roof or to brace the structure against wind. Removing one of those is not like removing a stud partition in a wood-framed house elsewhere. The wall may carry the roof, anchor straps that resist uplift, or tie the exterior walls together.

All of Miami-Dade is also inside the high velocity hurricane zone , where the Florida Building Code applies its strictest wind rules. Any new beam, post or connection has to be designed for gravity loads and for the uplift and lateral forces that hurricane winds put on the roof and walls, and the hardware used has to carry the right product approvals. A beam sized only for the weight above it can be too weakly connected to hold the roof down in a storm.

What the Engineer Does

Mistakes That Turn a Wall Removal Into a Problem

Most wall removal problems come from assumptions made before anyone looked at the structure. These are the ones we see most often.

How M&P Consulting Engineers Handles Wall Removals

Jonnatan R. Mendez, PE, SI , has more than 20 years of structural engineering in South Florida, beginning with residential and commercial structural design in Miami. He is a Florida Threshold Building Special Inspector with qualified plans examiner experience under the Florida Building Code, so he sees wall removal drawings from the reviewer's side as well as the designer's. His work covers concrete, masonry, steel, aluminum and wood, which matters in Miami-Dade homes where one wall can involve all of them.

We start by evaluating the existing structure and the load path, then design the beam, headers, columns, connections and supporting elements the change requires, and issue sealed drawings for the permit. We work with owners directly and with their contractors and designers, and our structural design projects range from new single family homes to repairs of fire-damaged high-rise condominiums. For residential alterations, we set the design schedule once we have reviewed the scope and the available information about the house.

A wall removal design follows a predictable sequence. Knowing it helps you plan the remodel around it rather than waiting on it.

Common Questions About Removing a Wall in Miami-Dade

The Short Version

The wall runs roughly through the middle of the house, parallel to the ridge, with ceiling joists or rafters landing on top of it.
There is a wall, beam or column directly above it on a second floor, or directly below it in a lower level.
The wall is thicker than the others, or is concrete block rather than wood studs and drywall.
The ceiling framing changes direction, or the trusses stop, at the line of the wall.
It is an exterior wall, or it was one before an earlier addition enclosed it, which is common in older Miami-Dade homes.

Condos and Townhomes

In a condominium, walls inside your unit can be structural concrete that belongs to the building, not to you. The association's declaration and rules usually require written approval before any wall is altered, and the association may require its own engineer's review. Townhomes often share walls that are rated fire separations as well as structure. In both cases the engineering question and the permission question have to be answered before the work starts.

What the Florida Building Code Requires

Work on an existing house is governed by the Florida Building Code, Existing Building . Removing or relocating a wall to reconfigure space is treated as a Level 2 alteration under that code, which brings in the structural requirements of its Chapter 8. Three of those requirements decide most wall removals.

Assuming a wall is not load-bearing because there is no second floor. In a single story home the roof itself is often carried by an interior wall.
Removing the wall before the permit is issued. Unpermitted structural work can stop a sale or a refinance, and the building department can require it to be opened up for inspection.
Setting new posts on an ordinary slab with no footing under them, where the concentrated load can crack the slab or settle over time.
Sizing the beam for weight but not connecting it for hurricane uplift.
Starting work in a condominium unit without the association's written approval.
Deciding between a dropped and a flush beam after the drawings are done, which sends the design back to the start.

The last clue catches many owners. A wall that used to be the back of the house often still carries the original roof, even after an addition was built beyond it, and it can look like any other interior wall once it has been painted and finished.

Alterations must not reduce the capacity of existing gravity load-carrying elements unless it is shown that those elements can still carry the design gravity loads the code requires.
Existing structural elements that pick up additional gravity load because of the alteration must comply with the Florida Building Code, Building, the code for new construction.
New structural elements, including their connections and anchorage, must comply with the Florida Building Code, Building.

Put plainly, when a bearing wall comes out, the weight it carried has to go somewhere, and every piece that now carries it, from the new beam down to the soil, has to be shown to work under current code. That includes the existing footing or slab under each new post, which was often never designed to take a concentrated load. Showing that on paper is engineering, and it is the reason the building department asks for it.

Permits in Miami-Dade

Miami-Dade County's rule is broad. Anyone who wants to construct, enlarge, alter, repair or demolish a building must first apply for and obtain a permit , and removing a wall is an alteration. Whether you apply to the county or to a city depends on where the house is. Unincorporated areas are permitted by the county, while many of the county's municipalities run their own building departments, so a house in Coral Gables , Doral , Hialeah or Homestead goes through that city.

The county now takes permit plans electronically, and plans submitted through its portal must be digitally signed and sealed by the design professional. For a structural alteration, that means drawings and usually calculations from a Florida licensed engineer, showing the existing condition, the wall to be removed, the new beam and supports, the connections, and any temporary shoring the contractor must install while the wall comes out. Plan reviewers check those drawings, and inspectors check the work against them before it is covered up.

Sealed Drawings and Florida Statute 471

Chapter 471 of the Florida Statutes governs the practice of engineering. It makes engineering the work of a licensed professional engineer, and it requires a licensee to sign and seal the documents they prepare, which is what makes the engineer personally responsible for the design. The seal tells the building department that a licensed person checked the loads and stands behind the result.

Owners sometimes read about an exemption in section 471.003 that lets a person practice engineering on property they own. The same sentence limits it to work that does not involve the public health, safety or welfare, and a change to the structure holding up a house that people live in is hard to separate from safety. In practice, the building department decides what it will accept for your permit, and for a bearing wall it will almost always want an engineer's seal. Florida's architecture statute, section 481.229, separately allows one and two family homes to be designed without an architect, so on most houses the engineer is the only design professional a wall removal needs.

Site visit to confirm what the wall is doing, including a look in the attic or above the ceiling at the roof framing, and at any floor or wall above.
Tracing the load path from the roof or floor, through the wall, down to the foundation, and identifying every load that has to be redirected.
Designing the replacement: the beam, whether wood, engineered lumber, steel or concrete, the posts or columns at each end, and the footings under them.
Designing the connections that resist uplift and lateral wind force, so the new framing holds the roof down as well as up.
Specifying temporary shoring so the structure is supported while the wall is removed and the beam is installed.
Issuing signed and sealed drawings and calculations for the permit, answering plan review comments, and being available when questions come up during construction.

Two design choices are worth settling early because they change cost and appearance. A dropped beam hangs below the ceiling and is simpler to install. A flush beam sits within the ceiling depth for a clean look, but often needs more work on the framing around it. Independent structural plan review can also be useful when a contractor or designer has already produced drawings and the owner wants them checked before submitting.

The High-Velocity Hurricane Zone: What FBC Chapter 16 and Miami-Dade Product Approval Mean for Your Project

Thu, 24 Sep 2026 16:51:19 GMT

The high velocity hurricane zone, or HVHZ, is the part of the Florida Building Code that applies only in Miami-Dade and Broward counties. It is the strictest wind standard in the state. Inside it, buildings are designed to wind loads under Section 1620 of Chapter 16, the building envelope has to resist windborne debris under Section 1626, and the windows, doors, shutters, roofing and other envelope products must carry a product approval that is valid for HVHZ use, most often a Miami-Dade Notice of Acceptance, or NOA.

For architects and contractors, the practical effect is that the structural design and the product approvals have to match each other. The engineer establishes the design pressures for every part of the building, the drawings show them, and each product specified or submitted has to be approved for at least those pressures, in that size, installed the way its approval describes. When those three things line up, permits and inspections move. When they do not, the job stops at plan review or at the final inspection, and the fix is usually expensive. The structural design and analysis work behind that match is where most HVHZ problems are prevented.

What the High Velocity Hurricane Zone Is

The HVHZ is a defined area, not a wind speed contour. The Florida Building Code applies its HVHZ provisions to Miami-Dade and Broward counties, and to every address within them, from the coast to the edge of the Everglades. Palm Beach County and the rest of the state are outside it, even where their design wind speeds are high. The provisions grew out of the South Florida Building Code, which the two counties strengthened after Hurricane Andrew in 1992, and they were carried into the statewide Florida Building Code when it took effect in 2002.

The HVHZ rules are not a single chapter. They are sections placed throughout the code, and a project in Miami-Dade or Broward has to meet the ones that apply to its structure and envelope. The main places they appear are these.

FBC Chapter 16 in the HVHZ

Section 1620: Wind Loads

Section 1620 requires buildings and structures in the HVHZ, and every portion of them, to be designed and constructed to Chapters 26 through 31 of ASCE 7, the wind load chapters of the standard. The 8th Edition of the Florida Building Code, in effect since December 31, 2023, correlates its wind criteria with ASCE 7-22 . One HVHZ rule has a large effect on the numbers: every building is treated as Exposure Category C unless Exposure D applies, so a site in a dense neighborhood does not get the lower pressures a suburban Exposure B site would get elsewhere.

Design wind speeds in the HVHZ are among the highest in the country. Miami-Dade County describes its product approvals as meeting HVHZ codes designed for winds up to 175 miles per hour, measured as a three-second gust, for typical buildings, and higher risk categories use higher values again. The speed for a specific project comes from the adopted map for its location and its risk category, and it drives both the main wind force resisting system and the components and cladding pressures that products are later matched against.

What It Means for Architects and Contractors

How the Design and the Approvals Fit Together

On a well-run HVHZ project the structural engineering and the product approvals are coordinated in a fixed order, so each step has what it needs from the one before. The sequence below is how that usually works.

Mistakes That Stall HVHZ Permits and Inspections

Most HVHZ problems are not about whether a building can be designed for the loads. They come from gaps between the design, the approvals and the installation. These are the ones that come up most often.

No. Slip resistance is one input. A sound opinion reads it alongside the surface condition, any contaminant, footwear, lighting, and maintenance history.

For the architect, the HVHZ changes what the drawings need to show. Building departments in Miami-Dade and Broward review product approvals against the design pressures on the permit set, so those pressures have to be there, zone by zone and opening by opening, not left for the window supplier to work out. Corner and edge zones of walls and roofs carry higher pressures than field zones, and a tall building has higher pressures at its upper floors, so one pressure value for the whole elevation is rarely right.

For the contractor, the product approval becomes a set of instructions. The unit that arrives on site has to be the tested unit, in a size the approval covers, fixed into the substrate the approval lists with the anchors and spacing it shows. Inspectors compare the installation with the approval, and a mismatch found at the final inspection is fixed by removing and reinstalling work that is already finished. That is the reason to resolve product selection during design, not during procurement. It matters just as much on existing buildings, where repair and replacement work after a milestone inspection or a recertification has to meet the same HVHZ approvals as new work.

The 9th Edition Change on December 31, 2026

The Florida Building Code updates every three years, and the next change is close. Miami-Dade's Product Control Section has announced that the 9th Edition of the code becomes effective on December 31, 2026, and that changes to the HVHZ sections of Chapter 15 and to the HVHZ test protocols will affect some current NOAs for roofing underlayments. Other product categories may see revisions as manufacturers update their approvals to the new edition.

For projects in design now, the practical step is to confirm with the building department which edition will govern the permit, based on when the application will be submitted, and to check the status of each specified approval shortly before submission rather than relying on the one in the specification. A roofing underlayment approval that was valid during design may need replacing if the permit falls under the 9th Edition.

How M&P Consulting Engineers Approaches HVHZ Design

Jonnatan R. Mendez, PE, SI , has more than 20 years of structural engineering in South Florida, beginning with structural design at Brindley Pieters & Associates in Miami and later as chief structural engineer at DLG Engineering. He is a Florida Threshold Building Special Inspector with qualified plans examiner experience under the Florida Building Code, and his work covers concrete, masonry, steel, aluminum, wood and post-tensioned systems, with wind and hurricane load analysis under ASCE 7.

Our HVHZ designs carry the design pressures on the drawings and are coordinated with the product approvals the architect and contractor intend to use, so the permit set, the submittals and the installation all point at the same numbers. We work from new construction and additions through repairs and retrofits of existing buildings in Miami-Dade and Broward, and our structural design projects range from new single family homes to repairs of fire-damaged high-rise condominiums.

Our forensic work informs the design side as well. Investigating how buildings perform in real storms, including the wind damage patterns described in our guide to hurricane damage claims , shows which connections and envelope details fail first, and those are the details we pay most attention to when the building is still on paper.

Common Questions About the High Velocity Hurricane Zone

ASCE/SEI 7-22, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, Chapters 26 to 31.

The Short Version

Chapter 15, where the HVHZ roofing sections govern roof systems, underlayments, attachment and roofing application standards.
Chapter 16, where Section 1620 sets HVHZ wind loads and Section 1626 sets the impact tests for windborne debris.
Chapters 19, 21, 22 and 23, which carry HVHZ sections for concrete, masonry, steel and wood construction.
The Test Protocols for HVHZ, a separate volume of the code containing the Testing Application Standards, such as TAS 201, TAS 202 and TAS 203, that products are tested against.

Impact Tests for Windborne Debris

Section 1626 is why HVHZ envelope products are different. Assemblies used up to and including 30 feet above grade must pass the large missile impact test, run on three specimens under TAS 201 and TAS 203. The large missile is a 9 pound piece of nominal 2 by 4 lumber, fired at the specimen at 50 feet per second, and specimens that survive the impacts are then put through cyclic pressure loading. Above 30 feet, the small missile test applies, using small steel balls under TAS 201, except that Risk Category IV essential facilities follow the large missile test at every height.

Two details in Section 1626 matter on site. The test specimen is the entire assembled unit, including its frame and anchorage, with fasteners identical in size and spacing to those used in the field, so the installation is part of what was approved. And where shutters or other external devices protect glazing, they must resist the large missile without deforming far enough to touch the glass they protect. The code also lists assemblies deemed to comply without testing, such as 8 inch concrete masonry walls built to the HVHZ masonry provisions.

Miami-Dade Product Control and the NOA

A Notice of Acceptance is issued by Miami-Dade County's Product Control Section, part of the Board and Code Administration Division. The county states that all products making up a building envelope , such as doors, shutters, windows, prefabricated buildings and truss plates, require an approval before they can be used in construction in Miami-Dade. NOAs also cover items such as railings, screen enclosures, awnings and precast elements, and manufacturers holding one must maintain a quality assurance program.

An NOA is specific, and that is its value. It lists the tested configurations, the maximum sizes, the approved positive and negative design pressures, the substrates the product may be anchored into, the anchor type and spacing, and an expiration date. The statewide alternative is a Florida Product Approval issued through the Florida Building Commission. It can be used in Miami-Dade and Broward only where it lists the product as approved for use in the HVHZ, and a statewide approval that does not say so is not enough.

Set the design criteria: risk category, design wind speed for the location, Exposure C or D, and the enclosure classification of the building.
Calculate the main wind force resisting system loads and the components and cladding pressures for each zone of the walls and roof, and show those pressures on the drawings.
Specify envelope products whose HVHZ approvals meet or exceed those pressures at the sizes shown, and confirm each approval is current.
Detail the openings and substrates to match the approvals, including bucks, sills, mullions and embedment, and design any structure the approval relies on, such as the wall or beam receiving the anchors.
Review the shop drawings and product submittals against the approvals and the design pressures before anything is ordered.
Verify the installation in the field against the approved anchorage and configuration before the work is closed up.

The same order applies to roofs. A roof system approval is tied to the deck it was tested on and to its attachment pattern, so the deck and the uplift pressures in each roof zone have to be settled before the roofing approval can be confirmed. Independent structural plan review before permit submission can catch gaps in that sequence while they are still inexpensive to fix.

Drawings with no components and cladding pressures, which leaves the reviewer nothing to check the product approvals against.
An expired approval, or one that has been superseded or revised, submitted from an old project file.
A product used larger than its approval allows, or at a location whose design pressure is higher than its approved rating.
Anchorage into a substrate the approval does not list, such as wood bucks where the approval covers only concrete or masonry.
Mulled window assemblies installed without an approval covering the mullion itself.
Roofing installed over a deck, or with a fastening pattern, different from the one the roof system approval was tested on.

Hurricane Damage Claims in Florida: Wind vs. Water, Pre-Existing Conditions, and the Engineer's Report

Thu, 24 Sep 2026 15:03:44 GMT

After a Florida hurricane, most disputed property claims come down to three questions: what force caused the damage, whether that damage was there before the storm, and whether the claim was reported in time. The first two are engineering questions. Wind and water are usually insured differently, because most homeowners and commercial property policies exclude flood and storm surge, which is covered by a separate flood policy. A single building can show both kinds of damage side by side, and the adjustment depends on which mechanism caused which part.

Answering those questions is forensic engineering , and a hurricane damage inspection engineer answers them from physical evidence rather than from the timing of the storm. That means documenting damage patterns, reading them against wind and flood signatures, dating distress that looks old, and comparing what failed with what the building was designed to resist under the Florida Building Code and ASCE 7. The result is a signed and sealed report stating what caused each element of damage, what did not, and why. For carriers, adjusters, owners and counsel, that report is only as good as the inspection behind it.

Wind vs. Water: Why the Line Matters

Most property policies treat wind and water as separate perils. FEMA states that most homeowners insurance does not cover flood damage , which is why flood coverage is sold as a separate policy through the National Flood Insurance Program or private flood carriers. Storm surge, the ocean pushed ashore by a hurricane, is flood under those policies. Rain that enters through an opening the wind has just torn in a roof or wall is often treated differently from rain that seeps through a roof that was already leaking, and the policy language decides which is which.

That split is why the engineering matters. On a coastal building, one storm can strip tiles off the roof, drive rain through a failed window, and push surge water three feet up the ground floor walls. Each of those can fall under a different coverage, a different deductible, and sometimes a different carrier. The engineer does not interpret the policy; the adjuster and counsel do that. The engineer tells them, element by element, which mechanism caused the damage, so the policy is applied to facts instead of assumptions.

Separating Wind Damage From Water Damage

Wind and water leave different evidence, and reading that evidence is the core of the inspection. Wind loads act on the whole building envelope, with the highest pressures at roof corners, edges and ridges, which is why ASCE 7 assigns those zones larger design pressures than the middle of the roof. Water acts from the ground up and leaves its marks at a consistent elevation. The engineer maps the damage against both patterns before drawing any conclusion.

Indicators of Wind Damage

Damage that follows the wind direction, with missing or lifted roof coverings concentrated at corners, eaves, rakes and ridges rather than spread evenly across the roof.
Creased or torn shingles, broken or displaced tiles, and peeled metal panels whose fracture and tear surfaces are fresh, with no weathering or staining at the break.
Failed connections along the load path, such as roof sheathing pulled off its fasteners, trusses lifted at their straps, or gable end walls pushed in or pulled out.
Impact marks and punctures from windborne debris, and broken windows or doors that let internal pressure build and push the roof up from the inside.
Interior water staining directly below a new opening in the roof or wall, where the opening came first and the rain followed it in.

Indicators of Flood and Storm Surge Damage

A horizontal water line at a consistent elevation across interior and exterior walls, often with a band of debris or sediment at the same height.
Silt, sand and marine debris deposited inside the building, with drywall, insulation and flooring saturated from the floor upward.
Scour and undermining at foundations, slab edges and pile caps, and structures shifted or floated off their foundations.
Breakaway walls, ground level enclosures and ground mounted equipment destroyed while the roof and upper floors remain largely intact.

Pre-Existing Conditions and Long-Term Deterioration

The second question in almost every hurricane claim is whether the storm caused the damage at all. Florida buildings age quickly. Salt air corrodes reinforcing steel, sun and heat break down roofing, and years of small leaks rot decking and stain ceilings. After a named storm, all of that distress is suddenly noticed and suddenly reported, and some of it has nothing to do with the event.

Engineers date damage from the physical evidence. A fresh fracture in a tile, a truss or a concrete edge is clean and bright; an old one is weathered, stained, or packed with dirt and organic growth. Corrosion stains running down a wall, spalled concrete over rusted rebar, and shingles that lost most of their granules years ago all point to a long process rather than a single day. Earlier repair patches, mismatched materials, and old ceiling stains with layered tide marks tell the same story.

Records of the building before the storm are more common than many parties realize. Condominium and cooperative buildings in Florida now carry milestone inspection reports , and older buildings in Miami-Dade and Broward carry recertification reports , both of which record structural condition at a known date. A roof permit, a recent survey, or an earlier claim file can do the same. An engineer who gathers those documents early can often show which cracks, spalls or roof deficiencies were already recorded before landfall and which appeared afterward.

The Codes Behind the Opinion

A causation opinion rests on how the building was supposed to perform. Chapter 16 of the Florida Building Code sets the structural design loads for buildings, including wind, using ASCE 7 as its reference standard. The 8th Edition of the code, in effect since December 31, 2023, correlates its wind criteria with ASCE 7-22 , which updated the wind speed maps and added provisions including tornado loads. In Miami-Dade and Broward, the High-Velocity Hurricane Zone provisions add stricter requirements on top of that.

That matters in a claim because design wind speeds describe what a building should resist, and the storm's actual winds can be compared with them. ASCE 7 wind speeds are 3-second gusts measured 33 feet above open terrain, set for the risk category of the building. If gusts at the site were well below the design speed and the roof still failed, the engineer looks harder at installation, attachment and deterioration. If gusts approached or exceeded design levels, wind becomes the more likely driver. The building's age matters too, since a house permitted under an older code was designed to a different standard than one built today.

The codes also shape the repair scope. Under Fla. Stat. 553.844(5) , when a roof system was built, repaired or replaced to the 2007 Florida Building Code or later, repairing 25 percent or more of it requires only the repaired portion to meet the current code, rather than forcing a full replacement. The 2007 code took effect on March 1, 2009, so the roof's permit date matters. Separately, Fla. Stat. 627.7011 requires homeowners insurers to offer law and ordinance coverage, which pays the added cost of meeting current code during repairs at limits of 25 or 50 percent of the dwelling limit. The engineer's report identifies which components need code upgrades, so those provisions can be applied to the actual building.

Common Questions About Hurricane Damage Inspections

No. Slip resistance is one input. A sound opinion reads it alongside the surface condition, any contaminant, footwear, lighting, and maintenance history.

Real buildings rarely show one pattern cleanly. A ground floor unit can have surge damage to its walls and wind driven rain damage to its ceiling at the same time. A sound report separates those areas, assigns each to its mechanism, and states the evidence behind each call. That is what lets the adjuster build an estimate that holds up when the claim is reviewed, appraised or litigated.

Claim Deadlines Under Fla. Stat. 627.70132

Florida's notice deadlines are short, and they set the pace for the engineering. Under Fla. Stat. 627.70132 , a new or reopened property insurance claim is barred unless notice is given to the insurer within one year after the date of loss, and a supplemental claim is barred unless notice is given within 18 months. For a hurricane, the statute fixes the date of loss as the date the hurricane made landfall. For tornadoes, windstorms and severe rain, it is the date NOAA verifies the event.

The statute does not change the separate time limit for filing a lawsuit under Fla. Stat. 95.11, but in practice the notice deadline drives the schedule. A supplemental claim for damage found later, such as water intrusion that appears months after the storm, has to be tied to the same peril, and that is a causation question. The later an engineer is brought in, the more the building has been repaired, dried out, or exposed to further weather, and the harder that link is to prove or to rule out.

What the Engineer's Report Should Contain

For a carrier or adjuster, the engineer's report is the document the coverage decision rests on. For counsel, it is the foundation of expert testimony that will be tested under Florida's Daubert standard in Fla. Stat. 90.702. A report that holds up in both settings usually contains the following.

The scope of the assignment and the questions the engineer was asked to answer, stated plainly at the start.
A site inspection record with the date, weather, areas accessed and not accessed, and a photograph log keyed to a plan of the building.
A document review covering permits, construction drawings, prior inspection and recertification reports, maintenance and repair records, and earlier claims where they exist.
Weather data for the event at or near the site, such as National Hurricane Center storm reports and nearby station records, compared with the building's design wind speed.
An element-by-element damage analysis stating the mechanism for each item, the evidence behind it, and any alternative cause the engineer considered and ruled out.
Conclusions and repair recommendations, including required code upgrades, signed and sealed by the responsible Florida Professional Engineer.

The same structure serves every party. An owner can see why part of a claim was supported and part was not, a carrier can see that the decision had a technical basis, and an attorney can see exactly which facts each opinion depends on.

Mistakes That Undermine a Hurricane Claim

Most disputes over hurricane claims are not about engineering principles. They come from evidence that was lost, never collected, or never written down. These are the problems we see most often.

Repairs or demolition before documentation. Tarps and emergency repairs are necessary, but removing damaged roofing, drywall or framing before it is photographed and measured erases the evidence of what caused it.
Relying on the storm date alone. Damage reported after a hurricane is not proof that the hurricane caused it, and a report that assumes causation from timing will not survive review.
Ignoring the building's history. Skipping permits, prior reports and earlier claims leaves pre-existing conditions unaddressed, and the other side will raise them.
Treating a mixed loss as a single peril. Calling everything wind, or everything flood, on a building that plainly shows both invites a challenge to the entire opinion.
Waiting too long to inspect. Every week after the storm brings more rain, more mold growth and more repairs, and the evidence moves further from its condition on the date of loss.

How M&P Consulting Engineers Approaches Hurricane Claims

Jonnatan R. Mendez, PE, SI , has spent more than 20 years on structural engineering, forensic investigations and property losses. Before founding M&P Consulting Engineers in Miami in 2019, he held senior roles with Rimkus Consulting Group, J.S. Held, where he was South Florida area lead, Halliwell Engineering Associates, and ProNet Group, where he directed complex loss work. That experience covers hurricane wind and water damage, roofing and building envelope failures, concrete deterioration and catastrophic losses.

Every assignment is handled directly by the principal, from the site inspection through the signed and sealed report. We work for insurance carriers, adjusters, property owners, condominium associations and attorneys, and our opinions rest on the physical evidence, the documents and the analysis, whoever retains us. The same method applies to any windstorm, as in our assessment of tornado damage at a Jupiter commercial property . For South Florida assignments, we schedule inspections within days, and sooner where there are safety concerns.

When a claim moves into litigation, Jonnatan has given testimony in Miami-Dade, Broward, Collier, Lee and Monroe County courts and in the U.S. District Court for the Southern District of Florida. Because the engineer who inspects the building also writes the report and gives the testimony, the method and the opinion stay connected from the first site visit to the courtroom.

The Short Version

Florida Condo Inspection Law in Plain English: A Guide for Boards and Property Managers

Wed, 23 Sep 2026 12:15:04 GMT

If you sit on a condo board or manage a building in Florida, two requirements now drive most of your structural compliance: the milestone inspection and the structural integrity reserve study , or SIRS. Between them they answer whether your building is structurally safe and whether you are setting aside enough money to keep it that way. This is the plain-English version, without the statute-by-statute detail, so you can tell what applies to your building and what you owe by when.

The Two Requirements, in One Paragraph

The milestone inspection is a physical inspection of the structure by a licensed engineer or architect. The SIRS is a funding study that projects the cost of maintaining and replacing your major structural components and sets a reserve schedule to pay for it. One asks whether the building is safe. The other asks whether the association can afford to keep it safe. Our Florida Milestone Inspections Explained article covers the inspection in depth, and the two requirements are meant to work together.

Which Buildings Are Covered

Both requirements apply to residential condominium and cooperative buildings that are three or more habitable stories tall. Four-family dwellings of three or fewer habitable stories are exempt. Mixed-ownership buildings, where only part of the building is condo or cooperative, are still covered, and all owners share responsibility for compliance. If you are not sure whether your building crosses the three-story line as the law counts it, that is worth confirming with an engineer before a deadline forces the question.

The Milestone Inspection, Plainly

Your building owes its first milestone inspection when it reaches 30 years of age, or 25 years if your local building department requires the earlier clock because of proximity to saltwater. After the first one, inspections repeat every 10 years. The inspection runs in two phases. Phase 1 is a visual assessment. If the inspector finds signs of substantial structural deterioration, Phase 2 goes deeper with the testing needed to evaluate it. Once the report is done, the association distributes a summary to owners. A building that has received a notice is already on the clock, so the practical move is to schedule the inspection early rather than near the deadline.

The SIRS, Plainly

The SIRS looks at your building's major structural components, the roof, structure and load-bearing walls, foundation, plumbing, waterproofing, and the rest, and estimates their remaining life and replacement cost. Those numbers become a reserve funding schedule. The key change for boards is that you can no longer vote to waive or underfund the reserves tied to these structural components. If a milestone inspection was done recently, it can feed the SIRS, which is why boards so often coordinate the two.

The Deadlines That Actually Matter

For most existing associations, the first SIRS was due by December 31, 2025. A building with a milestone inspection due on or before December 31, 2026 can coordinate the two, but the SIRS can be no later than that date. Milestone deadlines are keyed to your building's age and your local enforcement agency's rules. Miss either and you expose the association to code enforcement and to insurance problems, since Citizens will not cover an association that is out of compliance. The 40-year recertification comparison is worth a read if your building also falls under a county program.

How Boards Usually Handle Both

The efficient path is to run the milestone inspection and the SIRS structural assessment off a single engineering visit, so the condition findings and the reserve numbers come from the same read of the building. Hire a licensed engineer for the structural side, let a reserve professional build the funding schedule if you use one, and put the reserves in the budget. Associations in Broward and across the region handle it this way every year.

Where Boards Get Tripped Up

A few mistakes come up again and again. The first is treating the milestone inspection and the SIRS as one thing. They overlap, but they are separate filings with separate purposes, and doing one does not satisfy the other. The second is assuming a building is too small to be covered, when the three-habitable-stories line is measured in a way that can surprise you. The third is waiting for the county or state notice before scheduling anything. The notice starts a clock, and inspectors and engineers book up as deadlines cluster, so the associations that wait are the ones that scramble. The fourth is still budgeting as if the reserves can be waived. For the structural components a SIRS covers, they cannot. The last is hiring an inspector who is not a Florida-licensed engineer or architect, whose report the enforcement agency will not accept. None of these are hard to avoid, but each one costs time an association on a deadline does not have.

Common Questions About Florida's Condo Inspection Law

When is our building's inspection due?

Not for the structural components a SIRS covers. Those reserves can no longer be waived or reduced by owner vote.

Premises Liability and Fla. Stat. 768.0755: How Engineers Evaluate Slip, Trip and Fall Claims

Tue, 22 Sep 2026 12:00:08 GMT

In a Florida slip-and-fall case, two questions run in parallel: did the business have the knowledge the law requires under Fla. Stat. 768.0755, and was the walking surface actually unsafe by engineering standards. A premises liability expert witness works the second question in a way that speaks to the first. This is how an engineer evaluates slip, trip, and fall claims, and where the legal standard and the engineering method meet.

The Legal Standard: Fla. Stat. 768.0755

For a slip and fall caused by a transitory foreign substance in a business establishment, the statute puts the burden on the injured person to prove the business had actual or constructive knowledge of the dangerous condition and should have taken action. Constructive knowledge is the piece most cases turn on, and it can be shown by circumstantial evidence in one of two ways: that the condition existed for a length of time such that, in the exercise of ordinary care, the business should have known of it, or that the condition occurred with regularity and was therefore foreseeable. That word, foreseeable, is where engineering evidence earns its place.

Where the Engineering Comes In

The statute sets what has to be proven. The engineering shows whether a dangerous condition existed and whether it was the kind that recurs. A forensic engineering evaluation of the walking surface, the geometry, and the maintenance history gives the trier of fact something more concrete than testimony about a single moment. Done well, it connects the physical condition to the knowledge and foreseeability the statute asks about.

Measuring Slip Resistance

Slip resistance is measurable, not a matter of impression. Engineers test the walking surface using ANSI A326.3, which measures the dynamic coefficient of friction, or DCOF, with a calibrated tribometer. A wet DCOF of 0.42 is the widely used threshold for level interior floors that are expected to be walked on when wet, with higher thresholds for wet-plus conditions and exterior surfaces. Some engineers also use pendulum testing under ASTM E303 to produce a slip-resistance value. An important caveat, and one a careful expert will volunteer, is that a DCOF number is a comparison tool, not a guarantee that a floor is safe or unsafe. The measurement is one input, read alongside the surface condition, any contaminant, footwear, and the maintenance record, rather than a single number that decides the case.

Trip Hazards and Walkway Safety

Trip and fall claims turn on geometry more than friction. ASTM F1637, the standard practice for safe walking surfaces, addresses changes in level, ramps, slopes, drainage, gratings, and the transitions between surfaces. As a rule of thumb drawn from that standard, an abrupt vertical change in level of as little as a quarter inch can constitute a trip hazard, and changes beyond that generally require a bevel or a ramp. An engineer measures the actual geometry, compares it to the standard, and documents where the walkway departs from what a reasonably safe surface should provide.

Building the Opinion

A defensible premises liability opinion documents the surface conditions, the measurements, the lighting, and the maintenance practices, then maps each of them to recognized standards. That is what lets the opinion speak to foreseeability rather than to a single slip, and it is what keeps the testimony admissible when the methodology is challenged. Because these opinions are litigated under Florida's Daubert standard, the method behind the numbers matters as much as the numbers, which is why the same structural design and analysis discipline that supports a defect case supports a premises case.

Why Timing Matters: Preserving the Scene

Walking surfaces do not hold still. A spill gets cleaned, a worn tile gets replaced, a mat appears where there was none, and the hazard that caused the fall is gone within days. Slip-resistance and geometry measurements taken close in time to the incident are far more defensible than ones taken after the surface has been altered, because they describe the floor as it actually was. For the same reason, the maintenance and cleaning logs, incident reports, and photographs should be preserved early, before they are overwritten or discarded in the ordinary course of business. A repair the business makes after the fall can itself become evidence of the condition that existed before it. The practical takeaway for counsel is to get an engineer to the scene while the conditions can still be documented firsthand, rather than reconstructing them from memory months later once the case is well underway.

Common Questions About Slip and Fall Engineering

No. Slip resistance is one input. A sound opinion reads it alongside the surface condition, any contaminant, footwear, lighting, and maintenance history.

Structural Integrity Reserve Study (SIRS) in Florida: What the Law Requires and How It Gets Done

Thu, 17 Sep 2026 19:08:30 GMT

A SIRS is a financial planning document. It projects the remaining useful life and replacement cost of a building's major structural components, then sets a reserve funding schedule so the money is there when the work comes due.

It is not a safety inspection. A SIRS does not certify that the building is sound today. That is the job of the milestone inspection. The SIRS answers a money question: is the association setting aside enough, on the right timeline, for the structural work ahead.

A structural integrity reserve study, or SIRS, sets how much your condominium or cooperative association must reserve for specific structural components. Florida requires one for buildings three or more habitable stories tall under Fla. Stat. 718.112(2)(g) .

Boards routinely confuse a SIRS with a milestone inspection . They are two different requirements, they run on different statutes, and mixing them up leads to missed deadlines and underfunded reserves. This guide covers what a structural integrity reserve study is, which Florida buildings need one, what it has to cover, how the engineering portion is done, and the deadlines and funding rules that come with it.

What a SIRS Is

SIRS vs. Milestone Inspection

A milestone inspection or similar local inspection performed within the past five years, if it meets the SIRS requirements, can substitute for the visual inspection portion of the SIRS. That is why associations across Miami-Dade and Broward often schedule both off a single structural evaluation.

The two are complementary, and Florida law lets you time them together, but they answer different questions.

Which Florida Buildings Need a SIRS

The requirement applies to residential condominium and cooperative buildings that are three or more habitable stories in height. Four-family dwellings with three or fewer habitable stories above ground are exempt.

How a Florida SIRS Gets Done

Two wrinkles matter:

Habitable stories. A building with two residential floors over a parking level is treated differently than one with three residential floors. This resolves an ambiguity in the original 2022 language.
Mixed-ownership buildings. Under SB 154 (2023), the requirement reaches buildings that are, in whole or in part, subject to the condominium or cooperative form of ownership. Strictly commercial condo and co-op buildings are not subject to it.

What a Florida SIRS Must Cover

The study must address the building's major structural components. Under the current statute, that includes:

Roof
Load-bearing walls and other primary structural members
Floor
Foundation
Fireproofing and fire protection systems
Plumbing
Waterproofing and exterior painting
Windows and exterior doors

It also captures any other item with a deferred maintenance or replacement cost above the statutory threshold, where letting it fail would affect one of the components above. That threshold is inflation-adjusted each year and sits at $25,675 for 2026.

Most of a SIRS is a reserve-funding exercise, but it rests on a visual structural inspection. The work runs in a clear order:

A structural engineer or architect performs the visual inspection of each component.
Each component is assessed for condition and remaining useful life.
Replacement cost and timing are estimated for each.
A reserve funding schedule and baseline plan are built from that assessment.

Where a qualifying milestone inspection was performed within the past five years, step one can lean on it instead of repeating the visual work. The structural design and analysis behind the assessment is the part that has to hold up if the reserve numbers are ever questioned.

What Drives the Scope of a SIRS

No two assessments are identical. What drives the depth of the engineering portion:

Building size and number of stories
Age and construction type
Coastal exposure and its effect on framing, structure, and waterproofing
The condition found during the visual inspection
Whether a recent milestone inspection can carry the visual portion

Front-loading the assessment with an engineer who knows South Florida building stock keeps the funding plan defensible and avoids a repeat inspection later.

Deadlines and the No-Waiver Rule

Two points every board should have straight:

Existing owner-controlled associations that existed on or before July 1, 2022 had to complete their first SIRS by December 31, 2025. Buildings with a milestone inspection due on or before December 31, 2026 may coordinate the SIRS with it, but never later than December 31, 2026.
Reserves for SIRS-covered structural components can no longer be waived or reduced by owner vote, for budgets adopted on or after January 1, 2025.

There is also an insurance consequence. Citizens Property Insurance is barred from covering associations that have not met their milestone and SIRS obligations, and a willful failure to complete a SIRS is a breach of the board's fiduciary duty.

What HB 913 Changed in 2025

House Bill 913 , effective July 1, 2025, refined the framework:

The study must include a baseline funding plan that keeps the reserve balance above zero.
It must distinguish mandatory reserve items from other reserve items.
An association that has completed its milestone inspection may delay the SIRS for up to two budget years to prioritize the repairs the milestone identified.
Officers and directors must sign an affidavit acknowledging receipt of a completed SIRS.
Structural reports, including the SIRS and milestone reports, must be retained for 15 years.

For the official board-facing summary, the Florida DBPR maintains a condominium FAQ on how the milestone and SIRS timelines interact.

Coordinating a SIRS With a Milestone Inspection

If your building's milestone inspection is due in 2025 or 2026, coordinating the two off one structural evaluation saves money and keeps the findings consistent. The milestone inspection answers whether the structure is sound. The SIRS turns that condition assessment into a funding plan. Running them together means one engineer, one site visit, and one consistent read of the building.

MPC Engineering performs milestone and SIRS structural assessments for associations in Miami Beach , Sunny Isles Beach , Fort Lauderdale , Boca Raton , and West Palm Beach .

Getting the SIRS Structural Portion Right

The reserve numbers are only as good as the structural assessment underneath them. If your association is timing a SIRS with a milestone inspection, doing both off one evaluation is the efficient path, and it keeps the engineering read consistent from inspection to funding plan.

MPC Engineering provides SIRS structural assessments for condo and cooperative associations across South Florida. Contact us to schedule your assessment before the deadline pressure hits.

Broward County's Building Safety Inspection Program: Deadlines, Forms and What the Engineer Checks

Wed, 09 Sep 2026 18:49:51 GMT

What the Building Safety Inspection Program Covers

The program exempts U.S. and State government buildings, school buildings under Broward County jurisdiction, single-family, two-family, three-family, and four-family dwellings with three or fewer habitable stories above ground, fee-simple townhouses, minor structures under 3,500 square feet, and railroads. One detail worth knowing: an elevated deck, balcony, or parking garage attached to an otherwise exempt building doesn't automatically inherit that exemption. Those structures can still require inspection on their own.

If your Broward County building or association just received a Notice of Required Building Safety Inspection, the clock is already running. The county's Building Safety Inspection Program, known as BSIP, is administered by the Broward County Board of Rules and Appeals under BORA Policy 05-05, and it applies to almost every building in the county once it reaches 25 years old. This guide covers who it applies to, the deadlines, what the report has to contain, and how BSIP is different from Florida's separate, statewide milestone inspection law.

BSIP requires a Structural and Electrical Safety Inspection Report for buildings and structures 25 years of age or older, certifying that the building is structurally and electrically safe for continued occupancy. Unlike the state's milestone inspection, which is written specifically for condominium and cooperative ownership, BSIP applies broadly across building types: commercial, industrial, institutional, and residential alike. If your Broward building is a quarter-century old or older and doesn't fall into one of the exemptions below, this almost certainly applies to it.

Who Is Exempt

The 25-Year Trigger and the 10-Year Cycle

The initial inspection is due when a covered building or structure reaches 25 years of age. After that first inspection, subsequent inspections are required at 10-year intervals, counted from the original required inspection date, not from whenever the report actually gets filed. That last part matters: falling behind on one cycle doesn't reset or delay the next one.

The Notice, and the Two 180-Day Clocks

Broward's Building Official sends notice by certified mail each year, between June 1 and August 31, to owners of buildings due for inspection that cycle. From the date of that notice, the owner has 180 days to submit the completed, signed and sealed report. If the report identifies necessary repairs, the owner then has a second 180-day window, this one counted from the date of the report, to complete the work. Practically, that means a building with repair needs can be looking at close to a full year from notice to compliance, which is the argument for scheduling the inspection the moment the notice arrives rather than waiting.

What Goes Into the Structural and Electrical Safety Inspection Report

The report has to be prepared by a qualified Florida-licensed Professional Engineer or Florida Registered Architect and must certify the building's structural and electrical condition on Broward's designated Safety Inspection Report Form. In practice, the structural portion covers foundations, load-bearing elements, the building envelope and facade, balconies, railings, and roof structure, while the electrical portion, prepared separately by an electrical-discipline engineer, covers the building's electrical systems and safety. Both halves are required before the county considers the filing complete.

The $350 Filing Fee and Who Can Prepare the Report

Broward charges a $350 fee per building or structure, due at the time the report is submitted. That's separate from whatever your engineer charges for the inspection itself. Only a Florida-licensed Professional Engineer or Registered Architect can sign and seal the report; a home inspector, general contractor, or out-of-state engineer without Florida licensure cannot.

How BSIP Relates to Florida's Milestone Inspection Law

BSIP is a Broward County program. It is not the same thing as the milestone inspection required statewide under Fla. Stat. 553.899, which applies specifically to condominium and cooperative buildings three habitable stories or taller, on a 30-year clock statewide, or 25 years where the local enforcement agency requires it because of proximity to salt water. A Broward condominium that's 25 years old or older, three stories or taller, very often owes both requirements at once: BSIP to the county, and the milestone inspection under state law. The two have separate notices, separate reports, and separate filing offices, even when one engineering site visit can inform both. Our Florida Milestone Inspections Explained article covers the state law in full, and our Broward County BSIP page covers how M&P handles the structural side of this filing.

What Happens If You Don't Comply

Broward's Building Official enforces BSIP compliance, and a building that misses its deadlines is exposed to code enforcement action through the municipality with jurisdiction. Unlike Miami-Dade, which publishes a fixed citation amount for recertification cases, Broward's penalties are set and pursued at the municipal level, so what a building faces depends on which city it sits in. If your deadline has already passed, ask your city's building department where the file stands before code enforcement opens a case.

Florida Milestone Inspections Explained: Who Needs One, When, and What Phase 1 and Phase 2 Actually Involve

Wed, 02 Sep 2026 14:24:56 GMT

What a Milestone Inspection Is, and What It Is Not

The statute applies to any building that is three habitable stories or more in height and that is subject, in whole or in part, to condominium or cooperative ownership as a residential condominium or residential cooperative. Both conditions have to be true. A two-story condominium does not need one. A ten-story office building that has no condominium or cooperative units does not need one under this statute, although it may be covered by a county recertification program.

The statute specifically excludes single-family, two-family, three-family, and four-family dwellings with three or fewer habitable stories above ground.

If you sit on a condominium or cooperative board in Florida, you have probably heard the words milestone inspection more than once since 2022. The law behind it, Florida Statute 553.899 , was passed after the Champlain Towers South collapse in Surfside and has been amended three times since. This guide explains, in plain language, which buildings need a milestone inspection, when it is due, what happens in Phase 1 and Phase 2, and what your association has to do with the report. Our firm performs these inspections in Miami-Dade and across South Florida, and every fact below comes from the statute as it reads in 2026.

A milestone inspection is a structural inspection of a building, including its load-bearing elements and primary structural members and systems, performed by a Florida-licensed engineer or architect. Its purpose, in the words of the statute, is to attest to the life safety and adequacy of the structural components of the building and to determine any necessary maintenance, repair, or replacement of any structural component. It is not a code compliance inspection. The statute says directly that the purpose is not to determine whether the building complies with the Florida Building Code or the fire safety code.

It is also not a structural integrity reserve study, or SIRS. A SIRS is a financial study of the reserves an association must hold for structural items and comes from a different section of Florida law. And it is not the same as a county building recertification. Miami-Dade and Broward have run their own recertification programs for decades, and those come from county code, not from the state statute. A Miami-Dade condominium can owe both a county recertification and a state milestone inspection. Our guide to 40-year recertification versus milestone inspection covers that overlap.

Which Buildings Need a Milestone Inspection

When Your Milestone Inspection Is Due

The default rule is 30 years. A building must have its milestone inspection performed by December 31 of the year in which it reaches 30 years of age, counted from the date the certificate of occupancy was issued, and then every 10 years after that.

Local governments can shorten that to 25 years. The statute lets the local enforcement agency require the inspection at 25 years where local circumstances, such as proximity to salt water, justify it. Miami-Dade County uses this option for condominium and cooperative buildings within three miles of the coastline.

For older buildings, the statute set catch-up deadlines. A building that reached 30 years of age before July 1, 2022 had to complete its initial milestone inspection before December 31, 2024. A building that reached 30 years between July 1, 2022 and December 31, 2024 had to complete it before December 31, 2025. If your building falls in either group and has not had an inspection, it is already past due.

If the certificate of occupancy date is not available, the local building official's record of when the building was first occupied is used instead. The local enforcement agency can also extend the deadline for good cause if the association has already signed a contract with an engineer or architect and the inspection cannot reasonably be finished in time.

How the Notice Works

The local enforcement agency, usually your city or county building department, sends the association written notice by certified mail that the milestone inspection is required. The association then has 14 days to notify all unit owners of the required inspection and the date by which it must be completed. That notice can go out electronically to owners who have agreed to electronic notice, or by posting on the association's website.

Once the association receives the written notice, the clock starts. Phase 1 must be completed within 180 days. The statute defines completed as the engineer or architect having submitted the Phase 1 report to the local enforcement agency, so the deadline is about the report being filed, not just the site visit being done.

Phase 1: The Visual Inspection

In Phase 1, a licensed architect or engineer performs a visual examination of the habitable and non-habitable areas of the building, including the major structural components, and provides a qualitative assessment of the building's structural condition. The key question the engineer is answering is whether there are signs of substantial structural deterioration.

The statute defines substantial structural deterioration as substantial structural distress or substantial structural weakness that negatively affects the building's general structural condition and integrity. It specifically says that surface imperfections such as cracks, distortion, sagging, deflections, misalignment, signs of leakage, or peeling finishes are not substantial structural deterioration by themselves, unless the engineer or architect decides those surface signs point to something more serious underneath.

If the engineer finds no signs of substantial structural deterioration, Phase 2 is not required. The engineer files the Phase 1 report and the building's next milestone inspection is due in 10 years.

Phase 2: When It Is Required and What It Involves

Phase 2 is required whenever substantial structural deterioration is identified in Phase 1. Phase 2 can involve destructive or non-destructive testing at the inspector's direction. The statute gives the engineer wide latitude here. The inspection may be as extensive or as limited as necessary to fully assess the areas of distress, confirm whether the building is structurally sound and safe for its intended use, and recommend a program for fully assessing and repairing the damaged portions of the building.

When choosing where to test, the engineer must prefer locations that are the least disruptive and the easiest to repair while still being representative of the structure. If a Phase 2 inspection is required, the engineer performing it must submit a progress report with a timeline to the local enforcement agency within 180 days after the Phase 1 report was filed.

Who Can Perform a Milestone Inspection

Only an architect licensed under Chapter 481 or an engineer licensed under Chapter 471 of the Florida Statutes and authorized to practice in Florida can perform a milestone inspection. A home inspector, a general contractor, or an out-of-state engineer without a Florida license cannot. The statute does allow the inspection to be performed by a team, as long as a licensed architect or engineer acts as the registered design professional in responsible charge and every report is signed and sealed by the appropriate qualified team member.

There is also a conflict of interest rule worth knowing. An engineer or architect who bids on a milestone inspection must disclose in writing whether they intend to bid on any repair work the inspection recommends. Any contractor or design professional who bids on the recommended repairs cannot have an interest in the firm that did the inspection, or be a relative of someone who does, unless that relationship is disclosed to the association in writing. A contract that violates this rule is voidable by the association.

What the Report Must Contain and Who Receives It

After Phase 1 or Phase 2, the engineer or architect must submit a sealed copy of the inspection report, along with a separate summary of the material findings and recommendations, to the association, to any other owner of a portion of the building, and to the building official of the local government with jurisdiction. The report must, at a minimum:

Bear the seal and signature of the licensed engineer or architect who performed the inspection
State the manner and type of inspection that forms the basis of the report
Identify any substantial structural deterioration, describe its extent, and identify recommended repairs
State whether any unsafe or dangerous conditions, as defined in the Florida Building Code, were observed
Recommend remedial or preventive repairs for items that are damaged but do not rise to substantial structural deterioration
Identify and describe any items that require further inspection

Within 45 days of receiving the report, the association must distribute the inspector-prepared summary to every unit owner, regardless of what the report found, by mail or personal delivery and by email to owners who have consented to electronic notice. The association must also post the summary in a conspicuous place on the property and publish the full report and summary on its website if it is required to have one.

After the Inspection: Repairs and Timelines

If a Phase 2 report identifies substantial structural deterioration, the statute requires every county and municipality to adopt an ordinance setting a timeframe within which the association must schedule or begin repairs. Whatever the local timeframe is, repairs must begin within 365 days after the local enforcement agency receives the Phase 2 report. If the association does not submit proof that repairs have been scheduled or started within the required time, the local enforcement agency must review the building and decide whether it is unsafe for human occupancy.

That is the part of the law with real teeth, and it is the reason associations should engage an engineer for repair design as soon as a Phase 2 report is issued rather than waiting for the deadline. Our structural design and analysis team prepares sealed repair drawings and permit documents for exactly this situation.

How the Law Has Changed: SB 4-D, SB 154, and HB 913

Senate Bill 4-D, passed in a 2022 special session, created the milestone inspection requirement. Senate Bill 154 in 2023 revised it, including the shift to a 30-year statewide trigger with a local 25-year option. Further amendments followed in 2024 and in 2025 through House Bill 913. The statute's own history line lists each of these as chapters 2022-269, 2023-203, 2024-244, and 2025-175 of the Laws of Florida. Because the details have moved several times, always read the current version of Section 553.899 rather than a summary written in a previous year, including this one if you are reading it years from now.

40-Year Recertification in Miami-Dade vs. the State Milestone Inspection: Do You Need Both?

Wed, 02 Sep 2026 14:21:02 GMT

Two Requirements, Two Governments

The statute specifically excludes single-family, two-family, three-family, and four-family dwellings with three or fewer habitable stories above ground.

Every week we hear some version of the same question from a board member or property manager in Miami-Dade: we just did our 40-year recertification, so we are done with the milestone inspection, right? Or the reverse. The honest answer is that these are two different requirements from two different governments, and a lot of buildings in Miami-Dade County owe both. This article explains exactly how they differ and how to handle them without paying for two separate engineering projects.

The 40-year recertification is a Miami-Dade County program. It comes from Section 8-11(f) of the Code of Miami-Dade County, has existed since 1975, and is enforced by the Building Official of the county or of the municipality where your building sits. There are 35 municipalities in the county, and each one's building department handles recertifications inside its own limits. The notice you receive comes from whichever one has jurisdiction.

The milestone inspection is a State of Florida requirement. It comes from Florida Statute 553.899 , was created in 2022 after the Surfside collapse, and applies everywhere in Florida. It is enforced by what the statute calls the local enforcement agency, which in practice is the same city or county building department, but the rules it enforces are the state's rules, not the county's.

Side by Side: Recertification vs. Milestone Inspection

When Your Milestone Inspection Is Due

Who requires it: Recertification: Miami-Dade County Code. Milestone inspection: Florida Statute 553.899.

Which buildings: Recertification: most buildings in the county, residential and commercial, except single-family homes, duplexes, and small buildings with an occupant load of 10 or fewer and 2,000 square feet or less. Milestone inspection: only condominium and cooperative buildings that are three habitable stories or taller.

When it is first due: Recertification: 30 years for most buildings built in 1993 or later, 25 years for condominium and cooperative buildings three stories or taller within three miles of the coastline built in 1998 or later, with catch-up deadlines of December 31, 2024 for older buildings, and buildings built in 1982 or earlier that already recertified staying on their existing schedule.

Milestone inspection: 30 years from the certificate of occupancy statewide, or 25 years where the local enforcement agency requires it, which Miami-Dade does for coastal buildings.

How often after that: Both: every 10 years.

What is inspected: Recertification: structural and electrical, on the county's required report templates, including foundations, facade, parapets, seawalls, parking lot lighting and guardrail certificates, and infrared thermography on large electrical systems. Milestone inspection: structural only, in two phases, focused on substantial structural deterioration.

Who can perform it: Recertification: a Florida-registered engineer or architect with proven experience in that building type; the county asks for proof of structural specialization for the structural report and an electrical-discipline engineer for the electrical report. Milestone inspection: an architect licensed under Chapter 481 or an engineer licensed under Chapter 471.

Who gets the report: Recertification: the Building Official, through the county portal or the municipal building department. Milestone inspection: the association, any other building owner, and the building official, plus a summary to every unit owner within 45 days, posted on the property and on the association website.

If you miss the deadline: Recertification: late fee after 90 days, then a citation with an initial penalty of $510 and further penalties up to $10,000 per violation, and possible lien. Milestone inspection: the local agency may set timelines and penalties, and if Phase 2 repairs are not started within 365 days the agency must decide whether the building is unsafe to occupy.

Can One Inspection Satisfy Both?

Partly, and this is where a good engineer saves an association real money. In 2022, Miami-Dade County rewrote its recertification schedule specifically to integrate the new state law. That is why coastal condominiums in the county are now recertified at 25 years instead of 40. The county's own recertification page describes the current schedule as the integration of the state milestone requirement with the county program.

What that means on the ground is that a coastal condominium in Miami-Dade will get its recertification notice and its milestone requirement on the same cycle. One site visit by a qualified structural engineer can gather everything needed for both. But the outputs are different documents. The county wants its structural report on its own template, with the electrical report and the parking lot certificates alongside it. The state wants a milestone inspection report that meets the requirements of Section 553.899, with a separate summary for unit owners and the 45-day distribution that follows. Both have to be produced and both have to be filed with the right office. An engineer who only prepares the county packet leaves the association out of compliance with the state, and vice versa.

Our approach is to plan the site visit for both from the start. Learn more on our Miami-Dade 40-year recertification page and our milestone inspection services page .

Which One Comes First for a Miami-Dade Building

Take a 12-story condominium on Collins Avenue in Miami Beach with a certificate of occupancy from 1999. It is within three miles of the coastline, it is condominium ownership, and it is well over three stories. Under the county schedule it is due for recertification at 25 years, which was 2024. Under the state statute, Miami-Dade's 25-year local option means the milestone inspection was due by December 31, 2024 as well. Both landed at once. If that building has not been inspected, it is past due on both.

Now take a six-story rental apartment building in Doral, built in 1996, with no condominium units. It is inland and it is not condominium or cooperative ownership. The state milestone statute does not apply to it at all. The county recertification does, at 30 years, which is 2026. That building owes one inspection, not two, and the report goes on the county template only.

The difference between those two buildings is not the age or the size. It is the ownership type and the distance from the coast. Those two facts decide which rules apply.

What Boards Get Wrong

Assuming one inspection covers the other. It can cover the site work, but not the paperwork. Ask your engineer which reports they are producing and where each one is being filed.
Waiting for the final notice. Miami-Dade sends courtesy notices two years and one year ahead of the cycle. The final Notice of Required Recertification gives you 90 days. Boards that wait for the final notice end up hiring in a hurry.
Hiring someone who is not qualified. The county asks for proof of structural specialization. The state requires a licensed engineer or architect. A general contractor or home inspector cannot do either.
Forgetting the electrical report. The county recertification is not complete without an electrical report from an electrical-discipline engineer, plus the parking lot illumination and guardrail certificates where they apply.
