TL;DR
Florida's milestone inspection is a state-mandated structural review of buildings 3 stories or taller. Phase 1 is due when a building turns 30 (25 if within 3 miles of the coast), then every 10 years after. A licensed architect or engineer does the inspection under Fla. Stat. § 553.899. If Phase 1 finds substantial structural deterioration, a more invasive Phase 2 inspection follows.
What is the milestone inspection in Florida?
The milestone inspection is a structural safety inspection Florida law requires for condominium and cooperative buildings, and now most other buildings, that are 3 stories or more in height. A licensed architect or engineer has to perform it, and it's built around a two-phase process meant to catch structural problems before they become the kind of catastrophic failure that led to this law in the first place. The statute is Fla. Stat. § 553.899, part of the Florida Building Code framework administered with DBPR's involvement on the licensing side. It defines "milestone inspection" as "a structural inspection of a building, including an inspection of load-bearing walls and the primary structural members and primary structural systems as those terms are defined in s. 627.706, by a licensed architect or engineer authorized to practice in this state, for the purposes of attesting to the life safety and adequacy of the structural components of the building" [1]. This isn't a paperwork exercise. Phase 1 is a visual, non-invasive walk of the building's structure, foundation, roof, and common areas. If the inspector sees signs of "substantial structural deterioration" (the statute's actual phrase), Phase 2 kicks in, which can mean opening up walls, testing concrete, or other invasive methods to figure out how serious the problem is [1].
Which buildings need a milestone inspection in Florida?
Any building in Florida that is 3 stories or more above ground and is not a single-family, two-family, or three-family dwelling falls under the milestone inspection law. That covers condos, cooperatives, and most commercial and mixed-use buildings of that height, statewide, more than condos on the coast. The law was passed after the Champlain Towers South collapse in Surfside in June 2021, an event the National Institute of Standards and Technology is investigating as a full building failure under its National Construction Safety Team Act authority, with a final report expected to identify probable causes [2]. The Legislature responded in 2022 with SB 4-D, later folded into and amended within Fla. Stat. § 553.899 and the related condo statutes in Chapter 718 [1] [3]. Height is measured from the lowest point of pedestrian entry to the roofline, not counting basements or parking structures below grade in every case. Boards should confirm exact story count and measurement with a licensed engineer or their local building official, because edge cases (mixed-height buildings, additions, parking podiums) get argued over.
When is the milestone inspection due? 25-year vs 30-year rule
| Within 3 miles of coastline | Age 25 | Every 10 years | |
|---|---|---|---|
| More than 3 miles from coastline | Age 30 | Every 10 years | Boards in older buildings that missed a deadline because local officials hadn't yet issued notice should not assume they're in the clear. Confirm your building's exact age, coastal distance, and county-assigned deadline with your association's counsel and your local building department, since counties can set their own notification timelines within the statute's framework [1]. |
Timing depends on distance from the coastline. Buildings within 3 miles of the coast must complete Phase 1 by the time the building reaches 25 years of age, and every 10 years after that. Buildings more than 3 miles inland get 30 years for the first inspection, then also every 10 years [1]. Age is counted from the date of the certificate of occupancy. If a building already passed 30 years (or 25 near the coast) before the law's phase-in schedule caught up to it, local building officials set a compliance deadline, generally based on when the certificate of occupancy was issued relative to 2022 [1]. Here's the practical breakdown boards actually need: | Building location | First milestone inspection due | Repeat interval |
What happens during a Phase 1 milestone inspection?
Phase 1 is a visual inspection of the building's structure, done by a licensed architect or engineer, without any destructive testing. The inspector looks at load-bearing walls, the foundation, structural framing, and other primary structural components for visible signs of distress: cracking, spalling concrete, corrosion staining, deflection, water intrusion damage, that kind of thing. The inspector prepares a sealed report. If they find no signs of substantial structural deterioration, the report says so and the building is done until the next 10-year cycle. If they do find distress, the statute requires them to recommend a Phase 2 inspection and specify which portions of the structure need it [1]. This phase usually costs less and takes less time than people expect, but pricing varies a lot by building size and complexity (more on cost below). It is not the same thing as a reserve study, and it doesn't replace one. A milestone inspection is about structural safety right now. A reserve study is about funding future repairs and replacements over decades.
What triggers a Phase 2 inspection, and what does it involve?
Phase 2 is triggered when the Phase 1 inspector finds "substantial structural deterioration" and can't rule out a safety concern through visual review alone. Phase 2 allows destructive or semi-destructive testing: core samples of concrete, opening up finishes to see rebar corrosion, load testing, whatever the engineer needs to assess the actual condition of the structural system [1]. Phase 2 costs more and takes longer, because it involves lab testing and often follow-up structural analysis. There's no fixed statutory price, and costs depend heavily on building size, how many areas need testing, and how invasive the work has to be. If Phase 2 finds real structural problems, the board is now in a different world: repair scoping, contractor bids, possibly a hoa special assessment or condo special assessment insurance claim, and a compressed timeline set by the local building official. This is where reserve funding (or the lack of it) becomes a board's biggest problem, fast.
How much does a milestone inspection cost?
There's no statewide fee schedule for milestone inspections, and costs vary by building size, height, age, coastal exposure, and how much of the structure is accessible for review. Boards commonly report Phase 1 inspections running from a few thousand dollars for a small building to tens of thousands for a large, complex high-rise, but there's no authoritative statewide dataset that pins down an average, so treat any single number you hear as anecdotal. Phase 2, if triggered, adds meaningfully more: destructive testing, lab analysis of concrete cores, and engineering report time all add cost on top of Phase 1. Get multiple quotes from licensed architects or engineers, and ask specifically what's included (report format, number of site visits, whether Phase 2 scoping is bundled in if findings warrant it). Budget-wise, boards should treat the milestone inspection as a near-certain line item, not a maybe. If your building is approaching 25 or 30 years, get quotes now, not the year the deadline hits, because engineer scheduling backlogs are real in Florida right now given how many buildings are due at once.
What is a reserve study, and how is it different from a milestone inspection?
A reserve study is a financial and physical assessment of a building's common elements (roof, plumbing, paving, structure, and more) that projects when each component will need repair or replacement and how much it will cost. It's the basis for setting reserve contributions so the association isn't blindsided by a five- or six-figure repair with no money to pay for it. A milestone inspection asks: is this building structurally safe right now? A reserve study asks: what will everything cost to fix or replace over the next 25-30 years, and are we saving enough? They're related (a milestone inspection can surface findings that feed into reserve planning) but they are legally distinct requirements with different licensed professionals doing the work. Florida's Structural Integrity Reserve Study (SIRS) requirement, under Fla. Stat. § 718.112, is now mandatory for most condo associations with buildings 3 stories or higher, and it specifically requires funding reserves (no more waiving structural reserve items) for items like roof, load-bearing walls, floor, foundation, fireproofing, plumbing, electrical, waterproofing, and exterior painting [4]. For a full breakdown, see our reserve study guide and the hoa reserve study explainer.
What is a reserve study for an HOA?
For a homeowners association, a reserve study works the same way conceptually: an inspector or reserve specialist walks the common property (roads, clubhouse, pool, roofs on any shared structures, drainage), estimates the remaining useful life of each major component, and calculates what the HOA should be setting aside annually to cover replacement costs without a surprise special assessment. Most single-family HOAs don't own 3-story buildings, so they generally aren't subject to Florida's milestone inspection or SIRS statutes, which are keyed to condominium and cooperative buildings of that height. But HOAs with shared structures like clubhouses, gated entries, or parking garages that meet the height threshold should check whether those specific structures trigger milestone inspection requirements, because the statute is about the building, not the type of association. Even where it's not legally required, a reserve study is one of the cheapest forms of insurance a board can buy. It turns "we'll figure it out when the roof fails" into an actual funding plan members can see coming.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure that's right for every association, because it depends entirely on the age, size, and components of your specific property. The honest answer is: enough to fully fund the replacement cost of every major component by the time it reaches the end of its useful life, on a schedule a licensed reserve professional lays out for you. For Florida condos subject to the SIRS requirement, the law is specific about the mechanism, even if it doesn't hand you a magic number: associations must fund reserves for the components listed in the SIRS study, and boards generally can no longer vote to waive or reduce structural reserve funding for those specific items the way they once could for general reserves [4]. Some associations qualify for phased funding relief; check current status and any legislative updates with counsel, since this area has been amended multiple times since 2022. Our florida condo reserve fund relief page tracks changes here. As a rule of thumb boards can use for conversation (not compliance): if your reserve study shows you're funded below 30% of what full funding would require, you're in a range where deferred maintenance risk and future special assessment risk both climb sharply. That's a reserve-industry rule of thumb, not a statutory figure, so don't treat it as a legal threshold.
What is an HOA assessment, and what are HOA assessments used for?
An HOA assessment is a fee the association charges owners, authorized by the governing documents (declaration, bylaws) and, in many cases, state statute, to fund operating expenses and reserves. Regular assessments are the recurring dues everyone pays, monthly or quarterly, covering insurance, landscaping, management, utilities for common areas, and reserve contributions. A special assessment is a one-time (or limited-run) additional charge, levied when regular assessments and reserves don't cover a specific need: an unexpected repair, a milestone inspection Phase 2 finding, storm damage not fully covered by insurance, or a shortfall the reserve study exposes. Special assessments are legal in Florida under both Chapter 718 (condos) and Chapter 720 (HOAs), but boards generally have to follow notice and voting procedures set out in the statute and the association's own documents. For more detail on how special assessments get triggered and levied, see hoa special assessment.
Are HOA special assessments tax deductible?
For most owners, no. Special assessments for capital improvements or major repairs to common elements are generally not deductible on your personal federal income tax return, because the IRS treats them similarly to home improvement costs rather than a deductible expense. The IRS explains in Publication 523 that costs which add to a home's value, including a share of a co-op or condo association's capital assessments, are treated as basis adjustments, not deductions [5]. That said, they can increase your cost basis in the property, which can reduce capital gains tax when you sell. There are exceptions and nuances: if you rent out the unit, a portion of assessments tied to repairs (not improvements) on a rental property may be deductible as a business expense, and the line between "repair" and "capital improvement" gets technical fast. This is genuinely IRS territory, not condo-law territory, so this article isn't giving you tax advice. Talk to a CPA or tax attorney who can look at your specific assessment and how it was characterized (repair versus capital improvement) before you claim anything.
How does a board actually prepare for a milestone inspection deadline?
Start with the calendar math: get your certificate of occupancy date, measure distance to the coast (3-mile line, not "feels coastal"), and calculate your actual due year. Don't estimate. A wrong assumption here means missing a legal deadline, and local building officials do issue notices and can escalate to fines or unsafe structure proceedings if a board ignores it. Next, get quotes from licensed architects or engineers early, ideally 12 to 18 months before your deadline, because scheduling backlogs are real given how many Florida buildings are hitting 25- and 30-year marks in the same rough window post-Surfside. Ask what's included, what a Phase 2 trigger would cost on top, and get it in writing. Finally, coordinate the inspection timeline with your reserve study cycle and your ownership communication plan. Owners hate surprises more than they hate bad news, so a board that says "here's our milestone inspection date, here's our reserve funding status, here's what a Phase 2 finding would mean for assessments" six months ahead looks a lot better than one scrambling after a violation notice. This is the exact kind of scheduling and document tracking a board compliance kit is built to organize: it doesn't replace your licensed inspector or engineer, but it keeps deadlines, vendor quotes, and owner notices in one place instead of scattered across email threads.
What should boards do with Phase 1 or Phase 2 findings once they arrive?
Get the sealed report from the architect or engineer, distribute it to the board, and if your documents or counsel advise it, to owners, promptly. Some associations are required to record milestone inspection reports or make them available to owners; requirements can vary by local ordinance on top of the state statute, so check with your association's attorney on notice obligations specific to your county. If Phase 2 is triggered, get a repair cost estimate as early as possible, even a rough one, so the board can start the conversation with owners about funding options: reserves, a special assessment, a loan, or some combination. Waiting until the final engineering report is done before saying anything to owners tends to make the eventual assessment vote much harder, because people feel ambushed. Document everything. Inspection reports, board votes, engineer correspondence, and owner notices should all be dated, filed, and easy to produce if a state investigation, an insurer, or a future buyer's attorney asks for them years down the line.
Frequently asked questions
What is a reserve study?
A reserve study is a physical and financial assessment of a building's common elements (roof, plumbing, structure, paving) that estimates each component's remaining life and replacement cost, then sets a funding schedule so the association isn't hit with a surprise special assessment when something fails.
What is a reserve study for HOA use specifically?
For an HOA, a reserve study covers shared property like roads, clubhouses, pools, and any common structures, projecting replacement timelines and costs so annual dues can be set to fund those future repairs. Most single-family HOAs aren't subject to Florida's milestone inspection law unless they own a qualifying 3-story-plus structure.
What is an HOA assessment?
An HOA assessment is a fee charged to owners under the association's governing documents to fund operations and reserves. Regular assessments are recurring dues; special assessments are one-time charges levied to cover unexpected costs like repairs, insurance shortfalls, or reserve funding gaps.
How much should an HOA have in reserves?
There's no universal dollar figure; it depends on your property's age, size, and components as identified in a professional reserve study. For Florida condos under the SIRS law, structural reserve items generally can't be waived or underfunded the way general reserves once could be, per Fla. Stat. § 718.112.
How much does a reserve study cost?
Costs vary by building size and scope, typically ranging from roughly $1,000 to $2,000 for smaller associations up to several thousand dollars or more for large, complex properties with many components. Get quotes from licensed reserve specialists or engineers, since Florida's SIRS study has specific component requirements under Chapter 718.
What is the milestone inspection in Florida required for?
It's required for buildings 3 stories or taller (excluding single, two, and three-family homes) to verify structural safety at 25 years old (coastal, within 3 miles) or 30 years old (inland), then every 10 years, under Fla. Stat. § 553.899.
Who can perform a Florida milestone inspection?
Only a licensed architect or engineer authorized to practice in Florida can perform a milestone inspection and seal the report, per Fla. Stat. § 553.899. Boards should verify license status through DBPR before hiring.
What happens if a building fails Phase 1 of a milestone inspection?
Phase 1 doesn't produce a pass/fail grade exactly; if the inspector finds substantial structural deterioration, the report must recommend a Phase 2 inspection specifying which structural areas need invasive testing. The building isn't automatically condemned, but the timeline for fixing problems gets set by the local building official.
Are HOA special assessments tax deductible?
Generally no for personal residences; special assessments for capital repairs typically aren't deductible but can be added to your cost basis, reducing capital gains tax on a future sale, per IRS Publication 523. Rental property owners may have different treatment for repair-related portions. Confirm with a CPA.
How is a milestone inspection different from a SIRS study?
A milestone inspection checks current structural safety and is required under Fla. Stat. § 553.899. A Structural Integrity Reserve Study (SIRS) is a financial planning document required under Fla. Stat. § 718.112 that sets reserve funding for structural components. Both can be required for the same building, done by different scopes of work.
Does every Florida condo need a milestone inspection?
Only condo buildings that are 3 stories or taller need one under Fla. Stat. § 553.899. Smaller buildings (1-2 stories) aren't subject to this specific requirement, though they may still have SIRS or other reserve obligations depending on building type and local rules.
What is the 3-mile rule for Florida milestone inspections?
Buildings located within 3 miles of the coastline must complete their first milestone inspection at 25 years of age instead of 30, reflecting the added structural stress of salt air and coastal exposure. Distance is measured from the coastline as defined in the statute, not a general sense of proximity.
