Florida Condo Milestone Inspection Law: What SB-4D Means for Every Buyer

On June 24, 2021, Champlain Towers South in Surfside, Florida collapsed. Ninety-eight people died. The investigation that followed exposed a pattern that engineers and building officials had long known was common across Florida's coastal condo stock: deferred maintenance, underfunded reserves, and structural deterioration that associations had voted to ignore rather than pay for.

Florida's Legislature responded with Senate Bill 4-D (SB-4D), signed into law in May 2022. The core provision — now codified at Florida Statute 553.899 — established a mandatory statewide structural milestone inspection program for condominiums and cooperatives. It was the most significant change to Florida condo law in decades.

If you are buying a condo in Florida — anywhere in the state, not just Miami-Dade or Broward — this law affects the building you are considering and, directly, the financial exposure you are taking on. Here is what it actually requires.

Which Buildings Are Covered

Florida Statute 553.899 applies to condominium associations and cooperative associations with buildings that are three stories or more in height. Single-family homes, duplexes, and low-rise buildings under three stories are outside the scope of this law.

The three-story threshold is measured from the bottom of the lowest habitable floor to the top of the highest habitable floor — not including parking structures, mechanical rooms, or roof systems. A two-story building with a parking garage underneath it typically does not qualify. A three-story building with parking at grade level typically does.

The law applies across all of Florida's 67 counties. If the building has a certificate of occupancy and is three stories or taller, it is subject to the milestone inspection requirements regardless of whether it sits in a coastal county, a Central Florida suburb, or a rural area.

When the First Inspection Is Required

The milestone inspection clock starts with the original certificate of occupancy. Under the base rule in Florida Statute 553.899, a building must complete its first milestone inspection by December 31 of the year it reaches 30 years of age, and every 10 years after that.

For buildings that already existed when SB-4D was enacted in 2022, the initial deadline depended on age. Buildings with certificates of occupancy issued on or before July 1, 1992 — meaning they were already 30 years old or older — were required to complete their first milestone inspection by December 31, 2024. That deadline has already passed. If you are buying a condo built before 1993, the association should already have completed its first inspection or be in the process of addressing findings from it.

One complication: the original SB-4D text included a 25-year trigger for buildings within three miles of the coastline. Florida's HB 1021, passed in 2023, modified that provision. Under the current law, local governments in coastal jurisdictions have the authority to impose a 25-year trigger, but the statewide default is 30 years. Some municipalities and counties have adopted earlier triggers; others have not. If you are buying in a coastal market — Pinellas, Hillsborough, Sarasota, Charlotte, Lee, Collier, Miami-Dade, Broward, Palm Beach — verify whether the local government has adopted a 25-year requirement.

Phase One: The Visual Inspection

The milestone inspection is a two-phase process. Phase one is a visual examination conducted by a Florida-licensed architect or engineer. The inspector walks the building — including habitable and nonhabitable areas — and assesses the condition of major structural components: load-bearing walls, foundations, floor and ceiling systems, columns and beams, and the building envelope.

The inspector is looking for signs of significant structural deterioration: concrete spalling (the flaking or crumbling that results from embedded rebar corroding and expanding), post-tension cable issues, excessive cracking, moisture intrusion evidence, and any condition that suggests the structural system is compromised or degraded.

After phase one, the architect or engineer submits a sealed inspection report to the association and to the building official of the local government with jurisdiction. The report must include a separate summary of material findings and recommendations. Associations are required to distribute the summary to all unit owners within 45 days of receiving it.

If phase one finds no substantial structural deterioration, the inspection is complete. The building receives a clean milestone inspection record and the next inspection is due in 10 years.

Phase Two: Destructive and Non-Destructive Testing

If phase one finds substantial structural deterioration, phase two is required. Phase two goes beyond the visual: it may include materials testing, core sampling (removing small plugs of concrete for laboratory analysis), non-destructive testing methods like ground-penetrating radar or impact echo, or direct probing and removal of finishes to expose structural elements underneath.

The inspector determines the scope based on what phase one revealed. The law specifies that testing locations should be chosen to be as non-disruptive as possible while still being representative of the structure's condition. In practice, phase two often means portions of ceilings, walls, or balcony soffits are opened up, tested, and patched.

Phase two produces a detailed assessment of the extent of deterioration, a structural determination of whether the building is safe for continued occupancy, and a specific program for repairing distressed areas. The association must complete repairs within the timeframes the inspector specifies.

Phase two is where the financial exposure becomes real. Concrete restoration work — rebar corrosion, post-tension remediation, balcony structural repair — is expensive. The cost depends on the severity of deterioration, the building's construction type, how long the problems have been developing, and how accessible the damaged areas are.

The Structural Integrity Reserve Study (SIRS)

SB-4D also introduced the Structural Integrity Reserve Study, or SIRS, as a companion requirement to the milestone inspection. The SIRS is governed by Florida Statute 718.112(2)(g) for condominiums and parallel provisions for cooperatives.

Every condominium or cooperative with a building three stories or taller must have a SIRS completed by December 31, 2024, and every 10 years after that. The SIRS must be performed by a licensed engineer or architect and must assess the following nine structural components: roof, load-bearing walls or primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, and windows and exterior doors.

For each component, the SIRS identifies the estimated remaining useful life, the estimated replacement cost, and the recommended funding level for the reserve account covering that component. The study then calculates the reserve contribution needed each year to maintain full funding.

No More Reserve Waivers: The 2024 Funding Mandate

This is the most consequential financial change in SB-4D for existing condo owners and buyers: as of January 1, 2025, Florida condominium associations subject to the SIRS requirement can no longer allow unit owners to vote to waive or reduce reserve contributions for the nine SIRS structural components.

For decades before Surfside, Florida condo associations regularly held votes in which unit owners — often motivated by keeping monthly HOA fees low — voted to waive or reduce the reserves set aside for structural components. This is exactly how buildings accumulate deferred maintenance: the money to fix problems is never set aside because a majority voted not to fund it.

That is no longer legal for SIRS components. Associations must fund reserves at the level the SIRS recommends. The only flexibility remaining is whether to use the component (straight-line, per-item) method or the pooling method for calculating reserve contributions — both methods must result in the same required funding level, just allocated differently across the component pool.

For buyers, this matters immediately. If you are buying a unit in a building that has been underfunding structural reserves for years, the association is now legally required to catch up. That may mean significant increases in monthly assessments or a special assessment to bring the reserve fund to the required level. Ask for the SIRS report. Look at the current reserve funding percentage. A building at 20% funded is carrying very different risk than one at 80% funded.

Insurance Consequences for Non-Compliant Buildings

The milestone inspection law and the SIRS requirement have had a direct impact on Florida's already stressed condo insurance market. Carriers writing commercial property policies for condo associations — and individual unit owners' HO-6 policies — are asking about inspection status and reserve funding levels before issuing or renewing coverage.

Some insurers have declined to write or renew coverage for buildings that have not completed a required milestone inspection or that cannot demonstrate adequate reserve funding. Others have written policies at significantly higher premiums or with exclusions for structural deterioration. The practical effect: a building that is out of compliance with the milestone inspection law may face coverage gaps, non-renewal, or forced migration to Citizens Property Insurance, Florida's state-run insurer of last resort.

Fannie Mae and Freddie Mac have also updated their condo project eligibility guidelines post-Surfside. Buildings with significant deferred maintenance, inadequate reserves, or unresolved structural concerns face financing restrictions that limit buyers to cash-only purchases. If you are financing a condo, your lender will require a condo project questionnaire from the association that asks directly about inspection status, reserve funding, and pending special assessments.

“A low monthly HOA fee on a Florida condo built before 2000 is worth investigating closely. Either the building has a well-funded reserve account that carries no deferred maintenance, or the reserves have been repeatedly waived and the fee is low precisely because the association has not been setting money aside for the structural work that is now mandatory.”

What Buyers Should Ask Before Making an Offer

When I work with buyers on any Florida condo that is 25 years old or older, here is the documentation I request before we write an offer. The association is required by Florida law to provide most of this within the statutory disclosure window after contract execution.

1. Milestone inspection status and report: Is the building current? If the inspection has been completed, request the full report — not just the cover summary. Phase one findings that did not trigger phase two can still reveal conditions worth knowing about. If the inspection is overdue, ask the association for a written explanation and timeline.
2. Structural Integrity Reserve Study: Request the most recent SIRS. Note the date it was completed, the current reserve funding percentage for each SIRS component, and whether the association has adopted a plan to reach full funding. Any component under 50% funded on an older building warrants follow-up.
3. Special assessment history: Every dollar of structural repair work that was not covered by reserves was either assessed, financed, or deferred further. Ask for all special assessments in the last 10 years. Ask whether any are currently pending or have been discussed at board meetings.
4. The current reserve funding level and monthly HOA fee breakdown: Florida Statute 718.111 requires associations to provide a copy of the financial statements to prospective buyers upon request. The reserves line on the balance sheet and the reserve funding percentage are the two numbers that matter most.
5. Insurance policy status: Request the association's current master insurance policy declarations page. Has the insurer changed in the last two to three years? Has the premium increased more than 50%? Has any prior carrier declined to renew? All three are flags.
6. Any pending litigation: Associations involved in construction defect litigation, insurance disputes, or unit owner lawsuits are required to disclose this. Ongoing litigation can freeze financing and complicate sale.

Florida law gives buyers a statutory right to review condo documents — including the inspection reports and financial statements — and to cancel the purchase contract within three business days of receiving the complete package, with deposit returned. That window is not a formality. Use it.

County Recertification Programs: A Separate Layer

The statewide milestone inspection law under Florida Statute 553.899 is the baseline that applies everywhere in Florida. But Miami-Dade and Broward counties have their own local recertification ordinances that predate SB-4D by decades — Miami-Dade's 40-year building recertification program has been on the books since 1975.

If you are buying in South Florida, you are working with two overlapping frameworks: the statewide milestone inspection law and the county-level recertification ordinance. They are not identical and do not have the same triggers, deadlines, or report requirements — though a properly scoped report can satisfy both simultaneously.

I covered the county-level programs in detail in the companion post on Miami-Dade and Broward condo recertification — read that one if you are looking at buildings in those two counties specifically. This post covers the statewide framework that applies everywhere else in Florida, including Tampa Bay, the Gulf Coast, Orlando, and the Space Coast.

A Note on This Being Informational, Not Legal or Engineering Advice

Florida's condo laws have changed significantly since 2022 and continue to evolve. SB-4D was modified by HB 913 in 2023 and HB 1021 in 2023. Local governments have adopted varying interpretations of the 25-year coastal trigger. The DBPR and local building departments are still working through implementation details.

What I have written here is an agent-level overview for buyers doing preliminary due diligence. This is not a substitute for reviewing the actual inspection reports, working with a Florida real estate attorney on condo document review, or hiring an engineer who specializes in Florida structural assessments to give you an independent read on a specific building's condition.

Florida Statute 553.899 and Florida Statute 718.112(2)(g) are the governing texts. If you want to read them directly, the Florida Legislature's online Statutes database has the current versions.

If you are evaluating a specific condo in Tampa Bay, St. Petersburg, or Central Florida and want help thinking through the due-diligence questions — what documents to request, what numbers to focus on, what findings would give me pause before writing an offer — reach out. This is exactly the kind of Florida-specific nuance that matters.
