Milestone Inspection Requirements: Deadlines, Phases, and Costs

A Florida milestone inspection is a mandatory structural safety evaluation that condominium and cooperative buildings three or more habitable stories tall must complete once the building turns 30 years old, or 25 in certain coastal areas, and every 10 years after that.¹ It begins as a visual walkthrough by a licensed architect or engineer and only escalates to invasive testing if the inspector finds signs of substantial structural deterioration. The results carry weight well beyond the building itself: they drive repair deadlines, trigger disclosures to buyers, affect mortgage eligibility, and expose board members to personal liability if ignored.

Which Buildings Are Covered

The rule reaches any building that is three habitable stories or taller, as measured under the Florida Building Code, and that is subject in whole or in part to condominium or cooperative ownership.¹ Mixed-use buildings qualify so long as some portion contains residential dwelling units under a condo or co-op structure. A tower with retail at street level and condos above still needs the inspection.

Buildings that are entirely commercial, single-family homes, and residential buildings shorter than three stories are not covered. Townhome-style condominiums that share a declaration but sit under three stories also fall outside the requirement.

When the Inspection Is Due

The clock starts at the date on the building’s certificate of occupancy. The default rule is that the initial milestone inspection must be completed by December 31 of the year the building turns 30.¹ Follow-up inspections are required every 10 years after the first.

Local enforcement agencies can move that first deadline up. Where local conditions such as proximity to salt water warrant earlier scrutiny, the agency can require the initial inspection by December 31 of the year the building turns 25. Several South Florida jurisdictions have adopted this earlier threshold for coastal buildings. The same 10-year recurring cycle applies.

Transitional deadlines caught older buildings when the law took effect:

Buildings that reached 30 (or 25) years before July 1, 2022: initial inspection was due by December 31, 2024.
Buildings that reached 30 years between July 1, 2022, and December 31, 2024: initial inspection was due by December 31, 2025.

An association that has signed a contract with an inspector but cannot reasonably finish in time may request a good-cause extension from the local enforcement agency. The association must show it has a signed contract and that the delay is beyond its control.¹ Extensions are not automatic.

The 180-Day Notice Window

Local building officials are responsible for notifying associations that an inspection is due. Once the association receives that written notice, Phase 1 must be completed within 180 days.¹ Qualified inspectors in high-demand areas are often booked months out, so associations that wait for the notice before shopping for an engineer frequently struggle to make the window. Starting the search early is the practical move.

What Phase 1 Involves

Phase 1 is a qualitative assessment. The licensed professional walks through habitable and nonhabitable areas and visually examines the building’s primary structural components: load-bearing walls, columns, beams, floor slabs, and the connections between them.² The inspector is looking for substantial structural deterioration, which the statute defines as structural distress or weakness that negatively affects the building’s overall condition and integrity.

Surface-level imperfections like minor cracks, peeling finishes, or cosmetic sagging do not automatically count. Those conditions only matter if the inspector concludes they signal deeper problems. A hairline crack in a hallway wall is not the same thing as spalling concrete exposing corroded steel in a parking-garage column.

If the inspector finds no signs of substantial deterioration, Phase 2 is not required and the process ends with a written report.² For well-maintained buildings, that is a common outcome. The inspection is not a general building-code compliance check; its scope is limited to structural safety and maintenance needs.

What Phase 2 Involves

Phase 2 is triggered when the Phase 1 walkthrough identifies substantial deterioration. The statute lets the inspector use destructive or nondestructive testing methods and conduct a scope of work as extensive or as limited as needed to evaluate the areas of concern.¹ Engineers commonly use techniques such as ground-penetrating radar and concrete core sampling, though no particular method is required.

Testing locations must be chosen to minimize disruption to residents and keep repairs manageable, while still being representative of overall conditions. An engineer will not tear open a recently renovated unit if an equivalent test can be done in a utility area or parking structure.

Within 180 days of submitting the Phase 1 report, the inspector must submit a progress report to the local enforcement agency that includes a timeline for completing Phase 2.¹ The final Phase 2 report must recommend a program for assessing and repairing the damaged portions of the building.

What Happens After the Report

The association has 45 days from receiving the final report to distribute an inspector-prepared summary to every unit owner, whether the findings are favorable or alarming.¹ The summary goes out by U.S. mail or personal delivery to each owner’s address on file. The association must also post the summary in a conspicuous place on the property and publish both the full report and the summary on its website if it maintains one. The Department of Business and Professional Regulation requires the report to go to the local building enforcement agency as well.³ The 45-day clock runs from receipt of the report, not from when the board decides it is ready to share the news.

When a Phase 2 report identifies substantial deterioration, the repair clock starts. Local governments must adopt ordinances setting timeframes for scheduling or starting repairs. Regardless of the local ordinance, repairs must begin within 365 days at the outside.¹ If the association cannot show that repairs have been scheduled or started on time, the local enforcement agency must review the building and determine whether it is unsafe for human occupancy. That determination can lead to an evacuation order, and the enforcement mechanism does not pause for an association’s financial difficulty.

Funding often triggers special assessments. Associations may levy them under their governing documents, and in emergency situations the board can impose them without a unit-owner vote. Some associations secure a loan or line of credit to spread the burden.

Hiring the Inspector

The inspection must be performed by an architect licensed under Chapter 481 or an engineer licensed under Chapter 471 who is authorized to practice in Florida.¹ A team can handle the work, but a licensed architect or engineer must serve as the responsible design professional in charge, and every report must carry the appropriate seal.

Boards should pay close attention to the conflict-of-interest rules. An architect or engineer bidding on the inspection must disclose in writing whether they intend to also bid on any repair work the inspection might recommend. Any contractor or design professional who later bids on recommended repairs cannot have a direct or indirect financial interest in the firm that performed the inspection unless that relationship is disclosed in writing to the association. “Relative” for these purposes means anyone within three degrees of blood or marriage. If the required disclosure is never made, the repair contract is voidable and the professional faces discipline from their licensing board.

Disclosure in Sales and Mortgage Eligibility

Inspection results follow the property into every sale. For contracts entered into after December 31, 2024, both developer sales and resales of residential units must address the milestone inspection in the contract.

If the inspection has been completed, the seller must give the buyer a copy of the inspector-prepared summary, and the contract must contain an acknowledgment that the buyer received it.⁴ If the association is required to have one but has not completed it, the contract must contain a conspicuous statement saying so. If the association is not required to have one, the contract must say that. Omitting the topic is not an option.

Buyers have cancellation rights tied to these disclosures. In a developer sale, the buyer can cancel within 15 days (excluding weekends and legal holidays) after signing and receiving the required documents, and can extend the closing by up to 15 days to review the inspection summary. For resales between individual owners, the cancellation window is 7 days, with a matching 7-day extension right. A seller who leaves the disclosures out hands the buyer a contractual exit.

Financing is the other pressure point. Fannie Mae treats any project that failed a mandatory inspection related to structural safety, soundness, and habitability as a project in need of critical repairs, which makes the entire project ineligible for conventional mortgage purchase until the repairs are completed and documented.⁵ If a structural inspection completed within three years indicates unaddressed critical repairs, the project stays ineligible until an engineer confirms the safety concerns are resolved. A building with an overdue or failed inspection becomes much harder to sell. Cash buyers may still close, but the pool shrinks sharply when conventional financing is off the table.

Penalties and Board Liability

The statute lets local enforcement agencies set their own timelines and penalties for noncompliance.¹ Amounts and mechanisms vary. Some municipalities impose daily fines; others pursue injunctive relief. Local authorities, unit owners, and the state Division of Condominiums, Timeshares, and Mobile Homes all have standing to seek injunctions in court.

Board members have personal exposure. Florida law treats the failure to complete a milestone inspection or a structural integrity reserve study as a breach of fiduciary duty by the officers and directors of the association. The Division has authority to remove individuals from board or officer positions and can impose civil penalties of up to $5,000 per violation. Unit owners can bring their own lawsuits for breach of fiduciary duty, though they must show the board member’s conduct involved fraud, self-dealing, unjust enrichment, or similar misconduct to recover damages.

The worst-case outcome is not a fine. If the local enforcement agency determines the building is unsafe because repairs have not begun, residents may be ordered to vacate. That scenario is what the entire framework exists to prevent.

Estimated Costs

Phase 1 pricing tracks building size. Smaller buildings in the three-to-five-story range typically run between $10,000 and $15,000. Mid-rise buildings of 10 to 20 stories generally fall in the $20,000 to $40,000 range. High-rises above 20 stories can exceed $60,000. These figures cover engineering fees for the visual examination, reporting, and submission to the local enforcement agency.

Phase 2 roughly doubles the cost. Concrete coring, laboratory analysis, and access equipment like scaffolding or lifts all add up, and the final number depends on how many areas need invasive testing and how severe the deterioration proves to be.

Inspection fees are separate from the repairs the report may recommend. In buildings with significant deterioration, repair costs dwarf inspection fees by orders of magnitude. Treat the inspection as a known budgeted expense and plan for potential repair costs through the association’s reserve planning.

How This Differs From a Structural Integrity Reserve Study

A milestone inspection and a structural integrity reserve study are separate requirements. The milestone inspection evaluates whether the building is structurally safe right now. A SIRS estimates the remaining useful life of major building components and projects the cost to maintain or replace them over time. One is a safety assessment; the other is a financial plan. Neither replaces the other.

Florida law requires condominium associations to complete a SIRS at least every 10 years for each building on the property that is three habitable stories or higher. The study must cover at minimum eight categories: roofing, structural systems, fireproofing and fire protection, plumbing, electrical systems, waterproofing and exterior painting, windows and exterior doors, and any other item exceeding $25,000 in replacement cost whose failure would affect those structural components.⁶ The $25,000 threshold adjusts annually for inflation. Reserve funding based on the SIRS is mandatory and cannot be waived by a unit-owner vote.

The two overlap in practice. If the milestone inspection flags deterioration in the building’s structural systems, that finding feeds directly into SIRS reserve calculations. A clean inspection report keeps the SIRS straightforward. A Phase 2 report recommending significant repairs can blow a hole in the association’s reserve plan and trigger special assessments on top of regular dues.
