Florida statute 553.899 milestone inspection explained

Last updated 2026-08-14

What does Florida Statute 553.899 actually require?

Florida Statute 553.899 is the state law that created the milestone structural inspection program after the Champlain Towers South collapse in Surfside in June 2021. It applies to buildings that are three stories or more in height and requires a licensed architect or engineer to physically inspect the structure and certify its condition at set age intervals ^[1]. The statute's own language is specific about who has to do the work: the inspection must be performed by "a licensed engineer or architect authorized to practice in this state" ^[1]. The board can't assign this to a property manager or a general contractor, and it can't be waived by a vote of the membership. It's a state safety law, not a governing-document decision. The inspection happens in two phases. Phase 1 is a visual examination of the load-bearing structural components, no destructive testing. If the inspector finds "substantial structural deterioration," the law requires a Phase 2 inspection, which can include more invasive testing like core sampling, moisture probes, or removing finishes to look at rebar and concrete directly ^[1]. This statute doesn't stand alone. It works alongside Florida Statute 718.301 and 718.112, which set the reserve funding and disclosure rules tied to the same building age triggers. If your board is only tracking one of these, you're missing half the compliance picture. For the reserve-funding side of this, see our reserve study for condo association guide.

Which buildings need a milestone inspection in Florida?

The law covers buildings that are three stories or more, according to the height calculation methods local governments use for building code purposes ^[1]. Single-family homes, duplexes, and most townhomes under three stories are out. Condo, co-op, and mixed-use buildings that hit three stories are in, regardless of whether they're residential or commercial. The statute directs local enforcement agencies to identify buildings that fall under it and to notify owners by certified mail when their inspection is due ^[1]. In practice, many counties and cities publish their own tracking lists and portals, since 553.899 puts the notification and record-keeping duty on the "local enforcement agency," meaning your county or municipal building department, not the state. Here's the part boards get wrong most often: the height threshold is about the building's structural height classification, not the number of units or how the HOA markets the property. A three-story wood-frame condo over a parking podium can trigger the same requirement as a mid-rise concrete tower. If your association isn't sure whether a specific building qualifies, that's a question for your county building official or your association's engineer, not a guess based on the sales brochure.

When is the 30-year milestone inspection deadline in Florida?

30 years (non-coastal)	Dec. 31 of the year building turns 30	Fla. Stat. 553.899 [1]
25 years (within 3 miles of coast)	Dec. 31 of the year building turns 25	Fla. Stat. 553.899 [1]
Repeat inspection	Every 10 years after the first	Fla. Stat. 553.899 [1]
Buildings that hit the age threshold before July 1, 2022	Staggered deadlines through Dec. 31, 2024/2025 per local enforcement	Fla. Stat. 553.899, as amended by SB 154 (2023) [2]

The baseline rule is that a covered building must complete its first milestone inspection by December 31 of the year in which it turns 30 years old, measured from the date the certificate of occupancy was issued ^[1]. After that first inspection, the building needs a follow-up inspection every 10 years. There's a coastal exception that catches a lot of buildings by surprise. If the building is located within three miles of the coastline, the first inspection is due at 25 years of age instead of 30 ^[1]. "Coastline" here is a defined term tied to the tidal waters of the Atlantic Ocean or Gulf of Mexico, so barrier island towers, beachfront condos, and many Intracoastal-adjacent buildings fall into the 25-year track. For buildings that reached their 30th (or 25th, if coastal) anniversary before July 1, 2022, the statute set a grandfather clock: they had to complete the initial milestone inspection by December 31, 2024 ^[1]. Florida's legislature actually revised this timeline in 2023 (SB 154) to stagger the deadlines for older buildings across different windows through 2025, so if your building predates 2022 in this category, don't assume the 2024 date is still your firm deadline. Confirm with your association's counsel and your local building department, since some counties adjusted enforcement timing after the 2023 amendments. | Building age trigger | Inspection due by | Source |

What is a Phase 1 vs. Phase 2 milestone inspection?

Phase 1 is the entry point every covered building goes through. The licensed architect or engineer does a visual examination of habitable and non-habitable structural components, looking for signs of "substantial structural deterioration" like cracking, spalling, corrosion staining, or deflection in load-bearing members ^[1]. No destructive testing is required at this stage. If the Phase 1 report finds evidence of substantial structural deterioration, the law requires the inspector to recommend a Phase 2 inspection, and the building must proceed to it ^[1]. Phase 2 is more invasive: it can include core sampling of concrete, opening up walls or ceilings to inspect rebar, load testing, or other destructive or semi-destructive methods the engineer determines are necessary to fully evaluate the finding. Most buildings that make it through Phase 1 without red flags don't move to Phase 2. But when a Phase 2 is triggered, boards should expect it to add real time and real cost, easily tens of thousands of dollars depending on building size and what's found, plus the schedule risk of waiting on lab results and follow-up engineering reports. This is exactly the kind of expense that should already be lined up against reserve funding rather than sprung as a surprise special assessment. See our guide on hoa special assessment planning.

Who has to pay for the milestone inspection, and what does it cost?

The condo association or HOA covering the building pays for the milestone inspection. There's no state subsidy program for it. Costs vary widely by building size, height, and structural complexity, and Florida doesn't publish a statewide fee schedule, so any number you see quoted online is a market estimate, not a legal figure. Industry reporting and association attorneys have generally cited Phase 1 inspection costs somewhere in the low thousands to tens of thousands of dollars for a typical mid-rise condo, with larger or more complex buildings running higher, and Phase 2 work (if triggered) adding significantly more because of the destructive testing and lab analysis involved. Get quotes from more than one licensed engineer or architect; costs and scope of work can vary a lot between firms for the same building. This is a mandatory building expense, not a discretionary board decision, so it needs its own reserve line, similar to how a building funds roof or elevator reserves. If your board hasn't built the milestone inspection cost into next year's budget, that conversation needs to happen now, not after the county sends the notice.

What happens after the milestone inspection report is done?

The engineer or architect delivers a signed and sealed inspection report to the association and files it with the local building official ^[1]. From there, the statute puts a clock on the board: it "shall distribute a copy of the inspector-prepared summary" of the report to each unit owner, regardless of the results, and must post it in a conspicuous place, generally within 45 days of receiving it ^[1]. If the report finds substantial structural deterioration, the timeline compresses further. The local building official can require repairs to start on a specific schedule, and the board has to act, since deferring necessary structural repairs isn't a legal option once a licensed engineer has documented the problem in an official report. Boards sometimes treat the disclosure step as an afterthought, but it isn't optional and it isn't something a manager can quietly handle without board sign-off on timing and method. Owners have a statutory right to see this information, and getting the notice and posting requirements wrong creates its own liability separate from the structural issue itself.

How does the milestone inspection connect to Florida's reserve study requirements?

This is where a lot of confusion lives, so it's worth being precise. Florida Statute 553.899 is the structural inspection law. Florida Statute 718.112 is the condo reserve funding and disclosure law. They're triggered by similar building-age and height facts, but they're different statutes with different professionals doing the work. Under 718.112, condo associations for buildings three stories or higher have to get a "structural integrity reserve study" (SIRS) that's separate from a general reserve study, and it must be performed at least every 10 years by a person qualified to perform such a study, which the statute defines as an engineer or architect licensed in Florida, or a reserve specialist as otherwise defined by rule ^[3]. The SIRS looks at specific components: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing, electrical wiring, plumbing, and waterproofing, among others. A lot of the same structural information that comes out of a 553.899 milestone inspection feeds directly into the SIRS analysis. Smart boards schedule these together, or at least sequence them so the milestone inspection findings inform the reserve study numbers instead of running two disconnected studies that contradict each other. For the full breakdown on what a SIRS covers, read our reserve study explainer and our hoa reserve study guide.

What is a reserve study, and what is it for?

A reserve study is a professional assessment of a building's major components (roof, plumbing, structure, paving, and similar big-ticket items) that estimates their remaining useful life and projects how much money the association needs to save each year to replace or repair them without a surprise assessment. It's a financial planning tool built on physical inspection, usually done by a reserve specialist, engineer, or a firm that combines both disciplines. For Florida condos in buildings three stories and up, the SIRS version required under 718.112 is narrower and more structural than a traditional "full" reserve study. It focuses on the components listed in the statute, an inspector has to visually examine them, and the resulting report has to state, for each component, the deferred maintenance expense, and the estimated remaining useful life, and estimated replacement cost or deferred maintenance expense ^[3]. Associations still may want a broader reserve study covering non-structural items like paint, landscaping, or amenities, since SIRS doesn't replace that planning need for everything. The purpose is straightforward: without a study, boards guess at reserve contributions, and guessing is how associations end up with a $30,000 special assessment because nobody planned for a $400,000 roof replacement ten years out.

What are HOA and condo assessments, and how much should be in reserves?

An HOA or condo assessment is a fee the association charges owners to fund its budget, either the regular recurring assessment that covers day-to-day operating costs and planned reserve contributions, or a special assessment, a one-time or short-term charge levied when there isn't enough in reserves to cover an unplanned or under-funded expense. There's no single dollar figure or percentage that Florida law sets as "how much an HOA should have in reserves," because reserve needs depend entirely on the building's age, components, and the findings of its reserve study. What Florida law does require, for condos covered by the SIRS mandate, is that reserve funding be based on the study, not on an arbitrary board estimate, and it eliminated the ability for unit owners to vote to waive or reduce reserve funding for the SIRS-required components starting with the 2025 budget year, per the phase-in schedule in 718.112 ^[3]. A reasonable rule of thumb some reserve professionals use is funding reserves so the account holds at least 70% of the fully funded reserve balance recommended by the study, though this is an industry benchmark, not a Florida statutory requirement, and boards should treat it as a target range to discuss with their reserve specialist rather than a legal floor. If your board is trying to figure out how a special assessment gets triggered when reserves fall short, our hoa special assessment guide walks through the mechanics, and condo special assessment insurance covers what coverage options exist for owners facing a large one-time bill.

How much does a reserve study cost, and are special assessments tax deductible?

Reserve study costs vary by building size and scope. Full-service reserve studies for condo associations commonly range from around $3,000 to $15,000 or more depending on the number of components, building size, and whether a site visit and physical inspection are included versus a desktop update. A SIRS specifically, since it requires a licensed engineer or architect and physical inspection of structural components under 718.112, tends to run on the higher end of that range or above it for larger buildings, though Florida doesn't publish a fee schedule and DBPR doesn't set study pricing. On the tax question: special assessments paid by individual condo or HOA owners are generally not deductible on federal income taxes if they're for improvements or capital items, because the IRS treats them like a capital expenditure that adds to your cost basis rather than a deductible expense, similar to how home improvement costs work. IRS Publication 523 explains this directly for a homeowner's own residence: "Add otherwise deductible taxes and interest expenses (including special assessments) that you paid for someone else" is treated as an adjustment to basis rather than a current deduction in most non-rental scenarios, and the same publication instructs that assessments for capital improvements increase your basis rather than being deducted ^[4]. There are narrow exceptions, for example, if a portion of the assessment is specifically for deductible items like mortgage interest passed through, or if the unit is rental property where different capital expense and depreciation rules apply under IRS guidance. This isn't legal or tax advice, and owners should check with a CPA or IRS Publication 523 on capital improvements versus repairs, since individual situations differ and Florida statute doesn't govern federal tax treatment at all. For boards trying to get ahead of the paperwork side of all this, whether it's tracking the milestone inspection deadline, organizing the SIRS report, or building a communication timeline to owners, our $199 one-time Board Compliance Kit is built around the actual statutory deadlines for your building's age and coastal location. It doesn't replace your engineer or reserve specialist; it organizes what they produce and keeps the board on schedule for disclosure and reserve deadlines.

What should a board do right now to prepare for a milestone inspection?

Start by confirming your building's actual age and coastal distance with your county building department, since the 25-year versus 30-year trigger depends on facts your local enforcement agency tracks, not your best guess. Miami-Dade County, for instance, has run its own local 40-year (then 10-year recurring) building recertification program since the 1970s under county ordinance, separate from and older than the statewide 553.899 baseline; the county's recertification requirements are set out in Miami-Dade County Code Section 8-11 ^[5]. Next, get quotes from at least two or three licensed engineers or architects early. Firms doing this work statewide have been busy since 2022, and waiting until your deadline year to start the procurement process is how boards end up scrambling or missing the December 31 date. Cross-check your milestone inspection timeline against your SIRS deadline and your existing reserve study cycle. If they're not aligned, ask your reserve specialist and engineer whether combining site visits or sharing structural data makes sense, since redundant inspections cost the association money twice for information that overlaps. Finally, put the 45-day disclosure requirement on the calendar the moment you sign the engineering contract, not after the report lands. Boards that build the notice-to-owners step into the project timeline up front avoid the compliance failure that happens when a report sits on someone's desk for two months before residents ever see it. For the reserve-relief side of recent legislative changes, our florida condo reserve fund relief piece breaks down what flexibility, if any, currently exists and where the legislature has tightened rather than loosened requirements.

Frequently asked questions

What is a reserve study?

A reserve study is a professional assessment of a building's major components, like the roof, structure, and plumbing, that estimates remaining useful life and replacement cost, then recommends annual reserve contributions so the association can pay for future repairs without a surprise special assessment. Florida condos in buildings three stories or higher need a specific structural version called a SIRS under Fla. Stat. 718.112 ^[3].

What is a reserve study for an HOA?

For an HOA, a reserve study serves the same purpose as it does for a condo: it inventories shared components like roads, pools, and clubhouses, estimates when they'll need replacement, and calculates how much the HOA should save annually. Florida's SIRS mandate under 718.112 technically applies to condominium associations, not standalone HOAs, though many HOA boards use similar studies voluntarily for good financial planning.

What is an HOA assessment?

An HOA assessment is money the association charges owners, either the regular recurring assessment covering operating costs and reserve contributions, or a special assessment, a one-time or short-term charge when reserves don't cover an unexpected or underfunded expense like a roof failure or a milestone inspection Phase 2 finding.

How much should an HOA have in reserves?

Florida law doesn't set a universal dollar figure. For SIRS-covered condo components, funding must follow the reserve study's findings rather than an arbitrary board number, per 718.112 ^[3]. Some reserve professionals suggest targeting at least 70% of the fully funded balance the study recommends, but that's an industry guideline, not a statutory floor.

How much does a reserve study cost in Florida?

Costs commonly range from roughly $3,000 to $15,000 or more depending on building size, component count, and whether it includes a full site inspection. A SIRS, which requires a licensed engineer or architect under 718.112, tends to cost more for larger or taller buildings. Florida doesn't publish a fee schedule, so get multiple quotes.

Are HOA special assessments tax deductible?

Generally no. IRS Publication 523 treats special assessments for capital improvements as additions to your cost basis rather than a deductible expense, similar to home improvement costs ^[5]. Exceptions can apply for rental properties under different depreciation rules. Confirm treatment with a CPA, since Florida statute doesn't control federal tax rules.

When is the Florida milestone inspection deadline for a 30-year-old building?

The first milestone inspection is due by December 31 of the year the building turns 30 years old, based on its certificate of occupancy date, under Fla. Stat. 553.899 ^[1]. If the building is within three miles of the coastline, the deadline moves up to age 25 instead of 30.

Does Florida Statute 553.899 apply to HOAs or only condos?

It applies based on building height and structure, not association type. Any building three stories or more, condo, co-op, or otherwise covered under the statute's scope, needs a milestone inspection regardless of whether it's governed by a condo association or a homeowners association ^[1].

What happens if a milestone inspection finds substantial structural deterioration?

The engineer or architect must recommend a Phase 2 inspection, which can include destructive testing like core sampling or opening walls to examine structural members. The local building official can also require a specific repair schedule, and the board must act on it; deferring documented structural repairs isn't a legal option under 553.899 ^[1].

Who pays for the milestone inspection?

The condo association or HOA pays, typically through the operating budget or reserves. There's no state subsidy. Because it's a mandatory expense tied to a fixed statutory deadline, boards should budget for it years ahead rather than treating it as a surprise cost.

How is the 45-day disclosure requirement enforced after a milestone inspection?

Fla. Stat. 553.899 requires the association to distribute the inspector-prepared summary to unit owners and post it conspicuously, generally within 45 days of receiving the report ^[1]. Boards should confirm exact enforcement mechanics and timing with association counsel, since local building officials also receive the filed report directly.

Can a milestone inspection be waived by a board or owner vote?

No. It's a state safety statute, not a governing-document requirement, so neither the board nor the membership can vote to waive or delay it. The only flexibility built into the law is the staggered deadline schedule for buildings that already passed their age trigger before July 1, 2022 ^[1][2].
