Florida's milestone inspection law requires every condominium and cooperative building three habitable stories or taller to pass a structural inspection by December 31 of the year it turns 30, then every 10 years after that. A companion law makes windows and exterior doors a mandatory line item in each association's structural integrity reserve study (SIRS), and for budgets adopted since the end of 2024, associations can no longer vote to waive reserves for them. Between the two, Florida condo windows now sit on a legal clock.

The age math shows how many buildings that clock touches. Across the Florida Department of Revenue parcel rolls we keep in-house, Broward and Palm Beach counties carry 438,327 condominium parcels (DOR use code 04) with a recorded year built, and 379,064 of them, about 86 percent, were built in 1996 or earlier. Each of those units sits in a building that has either passed the 30-year mark already or reaches it in 2026. Parcel rolls count units rather than buildings, and the inspection mandate only reaches buildings of three habitable stories or more, so the figure describes the age of the condo stock, not a tally of inspections due. It still explains why so many South Florida boards are talking about windows this year.

We install impact windows and doors in these buildings, and we sit in on the board meetings where inspection reports get read aloud. This guide covers what the current law actually says, where openings show up in phase one and phase two findings, how the SIRS handles window reserves, and the decision path associations and unit owners walk after the report lands. It is an installer's field guide, not legal advice; your association's engineer and attorney are the ones to apply the statutes to your building.

Florida Milestone Inspection Rules in 2026

The milestone inspection requirement lives in Section 553.899, Florida Statutes. The legislature created it in 2022 with SB 4-D, eleven months after the Champlain Towers South collapse in Surfside killed 98 people, then reworked it in 2023 with SB 154 and amended it again in 2024 and 2025. Enough has changed that 2022-era summaries get the details wrong, including the widely repeated 25-year deadline for buildings within three miles of the coast. Here is the current law:

Question Current rule (FS 553.899, as amended through 2025)
Which buildings Condominium and cooperative buildings three habitable stories or more; one- to four-family dwellings are exempt
First inspection due By December 31 of the year the building reaches 30 years of age, measured from the certificate of occupancy
Coastal buildings No automatic 25-year trigger anymore; the local building department may require inspection at 25 years where local conditions justify it, such as proximity to salt water
Repeat cycle Every 10 years after the first inspection
Who performs it A Florida-licensed engineer or architect
Catch-up deadlines Buildings that turned 30 before July 1, 2022 owed inspection by December 31, 2024; buildings turning 30 between July 1, 2022 and December 31, 2024 owed it by December 31, 2025

The inspection itself runs in two phases. Phase one is a visual walk-through of habitable and nonhabitable areas with a qualitative read on structural condition, and it must be completed within 180 days after the building owner receives written notice from the local building department. The association has to tell unit owners about that notice within 14 days of receiving it.

If the phase one inspector finds no signs of "substantial structural deterioration," the process stops there until the next 10-year cycle. If the inspector does find them, phase two follows: a deeper assessment of the distressed areas that can include destructive or nondestructive testing. Once repairs for substantial structural deterioration are prescribed, they must be commenced within 365 days after the association receives the phase two report. Miss that window and the local building department must review whether the building is unsafe for human occupancy.

The paperwork duties matter to owners too. Within 45 days of receiving an inspection report, the association must send every unit owner the inspector-prepared summary, post it in a conspicuous place on the property, and publish the full report on the association's website if it is required to have one. The Division of Florida Condominiums at DBPR keeps a plain-language rundown of these inspection and reporting duties.

Where Windows and Openings Show Up in the Findings

A milestone inspection is not a window inspection. The statute defines substantial structural deterioration as structural distress or weakness that negatively affects the building's general structural condition and integrity, and it says surface imperfections, listing cracks, distortion, sagging, deflections, misalignment, "signs of leakage," and peeling finishes, do not qualify on their own unless the licensed inspector connects them to structural distress.

Openings still end up all over these reports, for two reasons.

First, the inspector's report must also recommend remedial or preventive repair for anything damaged below the structural threshold. Corroded window frame anchors, failed perimeter sealant, stained window heads, and spalled stucco at sills are exactly the findings that land in that remedial column. They are not emergencies, but once they are in a report that every owner receives by law, the board owns the follow-up.

Second, water that enters at an opening does not stay at the opening. In a coastal building, a failed sill pan or perimeter seal feeds moisture into the wall cavity and down to the slab edge, where chlorides reach the reinforcing steel. Corroding rebar expands and spalls the concrete around it. That is how a window problem crosses into a structural finding, most often at balcony slab edges beside sliding glass doors, where the concrete is thin, exposed, and holding a heavy door frame. When we pull 40-year-old frames out of oceanfront buildings, the anchors sometimes come out as rust flakes rather than screws.

The Surfside investigation is the reference point for why inspectors take deterioration seriously. NIST's technical findings on the Champlain Towers South collapse, released in June 2026, concluded the failure began at connections between garage columns and the pool deck, with thin safety margins traced to design and construction deviations compounded by decades of deterioration. Among the signs of distress NIST cataloged in the building's final weeks: a sliding glass door that came off its frame. Openings often telegraph structural movement before anything else does.

One caution the other direction: water at a window during a sideways-rain event is not proof the window failed. Florida test standards allow limited, controlled water entry under extreme wind pressure, which is why we wrote a separate explainer on wind-driven rain and what impact windows are actually rated to stop. An engineer reading a milestone report knows the difference between a design-level rain event and a chronic leak; owners reading the same report often do not.

How the SIRS Treats Windows and Exterior Doors

The structural integrity reserve study lives in Section 718.112(2)(g), Florida Statutes. Every residential condominium association with a building of three habitable stories or more must have one completed at least every 10 years, prepared by an engineer, architect, or a certified reserve specialist. Associations that existed on July 1, 2022 owed their first SIRS by December 31, 2025, or December 31, 2026 for those pairing it with a milestone inspection.

The statute names the items the study must cover at a minimum:

SIRS mandatory item Where openings fit
Roof
Structure, including load-bearing walls and other primary structural members and systems Slab edges and lintels around openings
Fireproofing and fire protection systems
Plumbing
Electrical systems
Waterproofing and exterior painting Perimeter sealant joints, sill pans, stucco at openings
Windows and exterior doors The frames, glazing, and hardware themselves
Any other item over $25,000 whose deferred maintenance would affect the items above Sliding glass door replacement programs often land here

Windows are not an afterthought in that list; they are a named category with their own remaining-useful-life estimate and a funding schedule attached. A reserve professional walks the building, estimates how many years the existing windows and doors have left, prices their replacement, and the association must budget reserves against that schedule.

Two funding rules give the schedule teeth. For budgets adopted on or after December 31, 2024, members of a unit-owner-controlled association that must obtain a SIRS may not vote to waive or underfund reserves for the listed items. The decades-old habit of zeroing out reserves to keep monthly dues low is gone for windows, roofs, and waterproofing. The 2025 amendments added flexibility rather than escape hatches: an association may pause reserve contributions for up to two consecutive budget years after completing a milestone inspection to put money into the repairs it surfaced, and it may fund reserve obligations through a loan or line of credit with member approval.

One nuance decides everything about who pays: the SIRS covers what the association maintains. Portions of the property that the declaration of condominium assigns to someone other than the association fall outside the study. In buildings where the declaration makes each owner responsible for the windows and doors serving their unit, there may be no association reserve line for them at all, and replacement lands on owners individually. Our guide to impact windows in Florida condos walks through how declarations split that responsibility and how to find yours.

Repair, Replace, or Assess: The Association's Decision Path

When a milestone report and a SIRS arrive in the same two-year window, boards face a fork we now watch play out across South Florida: keep patching openings one unit at a time, or run a building-wide replacement program on the association's schedule.

The milestone timeline shapes that choice. Structural repairs must start within 365 days of a phase two report, and structural work on a mid-rise or high-rise means swing stages, scaffolding, engineering, and permits either way. Mobilizing that access twice, once for concrete restoration and again for windows a few years later, means paying for it twice. That is why openings replacement so often rides along with restoration work: the deterioration around the frames is part of the repair scope, and the access cost is already sunk. On towers, staging and logistics dominate the project; our piece on impact window projects in Aventura high-rises covers how that work actually gets sequenced.

Paying for it comes down to four tools, and boards usually combine them:

  1. Funded reserves. The SIRS schedule is the plan; a building that has been funding its windows line simply executes it.
  2. A special assessment. A one-time levy on owners, sized to the project and divided per the declaration. Buildings that waived reserves for decades and now face a window replacement special assessment are paying the deferred bill all at once, which is exactly the pattern the post-Surfside laws were written to end.
  3. A loan or line of credit. Now expressly permitted for reserve funding, this spreads the cost across years of dues instead of one assessment.
  4. The reserve pause. After a milestone inspection, up to two budget years of reserve contributions can be redirected into the repairs the inspection surfaced, by majority vote.

Whether to repair or replace the openings themselves is an engineering and arithmetic question, and the SIRS frames it: if the study gives the existing windows a short remaining useful life, money spent rebuilding corroded frames buys very few years. Replacement resets the reserve schedule, and in the wind-borne debris region it also moves the whole envelope to current impact-rated windows and doors, with the insurance and code position that comes with that. None of this overrides an individual owner's separate statutory right to install code-compliant hurricane protection at their own unit, a process with its own rules that we cover in our guide to association approval for impact windows.

What Unit Owners and Buyers Should Know

If you own a unit, the documents to read come in a fixed order. The declaration of condominium tells you whether the windows serving your unit are common elements the association maintains, limited common elements, or your personal responsibility. The milestone summary, which the association must send you within 45 days of receiving the report, tells you what the engineer saw. The SIRS tells you whether money exists for what comes next.

Three questions for your board cover most of it. Has the building completed its milestone inspection and its SIRS, and where are the reports? How does the declaration classify windows and exterior doors? And does the current budget fund the reserve schedule, or is a special assessment or loan under discussion? Answers to all three exist in writing; a board that cannot produce them is behind the statute.

If you are buying into a Florida condo building of three stories or more, the same documents belong in your due diligence beside the inspection of the unit itself. A building that turned 30 with no milestone report on file, or a SIRS with a large unfunded windows line, is a known future cost you can price before you sign. The age figure from our parcel data cuts both ways here: with roughly 86 percent of Broward and Palm Beach condo stock built before 1997, buildings that have already done this work stand out, and they say so in their listings.

Owners on the hook individually should not wait for the building's timeline. Where the declaration puts windows on the unit owner, a milestone or SIRS finding about deteriorated openings can turn into a compliance letter with your name on it, and replacing on your own schedule beats replacing on a deadline. The approval mechanics, product matching, and paperwork for that path are covered in the two condo guides linked above.

Next Steps
