What SIRS and Milestone Inspections Require in South Florida
In South Florida, condominium and cooperative buildings of three or more habitable stories must now meet two distinct requirements under state law: a milestone structural inspection and a Structural Integrity Reserve Study (SIRS). These mandates apply across Miami-Dade, Broward, Palm Beach, and Monroe counties, and they directly shape how building owners and boards plan for major mechanical systems like central chiller plants and cooling towers.
The framework began with Florida Senate Bill 4-D in 2022 and was amended by Senate Bill 154 in 2023 and House Bill 913, which took effect July 1, 2025. The milestone inspection is the structural assessment, while the SIRS is the financial study that establishes reserves for covered building components. Together they are designed to ensure buildings are both structurally sound and financially prepared for major repairs and replacements.
A 'habitable story' is defined by reference to the Florida Building Code as space used for living, sleeping, eating, or cooking. Spaces such as garages, storage areas, and hallways generally do not count. Because this definition determines whether your building is in scope, confirm your building's classification with your engineer or association attorney.
Key Deadlines: When the First SIRS and Milestone Inspection Are Due
For unit-owner-controlled associations that existed on or before July 1, 2022, the initial SIRS deadline is December 31, 2025. If your association is also required to complete a milestone inspection on or before December 31, 2026, the SIRS may be coordinated with that inspection and completed by December 31, 2026. This coordination can reduce duplicated engineering work, but the eligibility window is specific, so verify your dates with your professional team.
Milestone inspections are tied to building age. The initial inspection is generally due by December 31 of the year a building reaches 30 years old, or 25 years old for buildings within three miles of a coastline, which captures much of South Florida's coastal building stock. Subsequent SIRS updates are required at least every ten years.
These statewide rules sit alongside long-standing local programs. Miami-Dade and Broward counties have historically run 40-year building recertification programs, which have been folded into the milestone inspection framework. Because timing and triggers can differ by jurisdiction, confirm your specific schedule with the appropriate local building department.
Which Components SIRS Must Fund, and Where HVAC Fits
A SIRS must establish reserves for a defined set of structural and building-protection components: roof, load-bearing structure, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, and windows and exterior doors. A SIRS must also address any other item with a deferred-maintenance or replacement cost above the statutory threshold, which HB 913 raised to $25,000 (indexed to inflation).
A central chiller plant, cooling towers, and large building HVAC systems are major capital items that interact with this study. They are typically among the largest line items in a condominium or commercial building's reserve and capital plan, and their condition affects both budgeting and the building's overall mechanical reliability. Confirm with your reserve study professional how your specific HVAC assets are classified within your study.
Importantly, the statute provides that a component with a remaining useful life of more than 25 years need not be reserve-funded for full replacement; in that case, reserves cover only the recommended deferred-maintenance amounts. Because remaining useful life is an engineering judgment specific to each system, an accurate assessment of your HVAC equipment directly affects how much you are required to reserve.
Board Fiduciary Duty and Competitive Bidding
Officers and directors who willfully and knowingly fail to complete a required milestone inspection or SIRS breach their fiduciary duty under Florida Statutes section 718.111(1) and can face personal liability. Under HB 913, board members are also required to sign an affidavit acknowledging receipt of the completed SIRS report. Non-compliance fines are set by local ordinance and vary by jurisdiction, so confirm the penalties that apply in your county or municipality with your association attorney.
Procurement rules also matter when you move from study to action. Florida Statutes section 718.3026 generally requires associations to obtain competitive (multiple) bids when a contract exceeds 5 percent of the association's total annual budget, including reserves. There are exceptions, including emergencies, sole-source providers, certain professional services, and a two-thirds opt-out available to associations of 10 or fewer units.
For a chiller or cooling-tower replacement, which can easily exceed that 5 percent threshold, this means boards typically need multiple, comparable, bid-ready proposals. HB 913 also requires design professionals and contractors who bid on inspections or the SIRS to disclose in writing if they intend to bid on the resulting repair or replacement work, which is a conflict-of-interest safeguard boards should be aware of.
Turning Compliance Into a Defensible HVAC Capital Plan
A SIRS is only as good as the engineering inputs behind its mechanical components. For large HVAC assets, that means a credible remaining-useful-life assessment and a realistic replacement-cost estimate that reflects current South Florida equipment, labor, and code conditions. These figures feed directly into the reserve schedule and influence the size of contributions or special assessments owners ultimately face.
Maza HVAC supports building owners and boards with remaining-useful-life assessments and replacement-cost estimates for chiller plants, cooling towers, and large air-handling systems, and we prepare bid-ready proposals that boards can present alongside competitive bids. Proactive maintenance agreements can also extend equipment life, which may affect how components are treated in your reserve study.
