TL;DR
Florida law requires condo associations with buildings 3 stories or higher to get a Structural Integrity Reserve Study (SIRS) covering specific components, then fund full reserves for those items with no waiver allowed. Most buildings needed their first SIRS by December 31, 2024, tied to milestone inspection timing. Confirm your exact deadline and scope with your association's counsel and county building department.
What is a SIRS under Florida law?
A Structural Integrity Reserve Study (SIRS) is a study, done by a licensed engineer or architect (or in limited cases someone qualified under DBPR rules), that inspects specific structural and life-safety components of a condo building and estimates the remaining useful life and replacement cost of each one. It's not the same thing as a general reserve study, though people mix up the terms constantly. Florida Statutes section 718.112(2)(g) spells out what has to be in it. The study must include, at minimum: roof, load-bearing walls or other primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, windows, and "any other item that has a deferred maintenance expense or replacement cost that exceeds $10,000 and the failure to replace or maintain such item negatively affects the items listed... as determined by the visual inspection portion of the structural integrity reserve study" [1]. The study has to estimate the remaining useful life of each component and the estimated replacement cost, or the estimated cost of the deferred maintenance. That's the number the board then has to fund in reserves, dollar for dollar, no more waiving or underfunding these line items the way boards used to be able to vote to do. For background on how a SIRS differs from a standard reserve study, see our reserve study explainer.
Which buildings actually have to do a SIRS?
The SIRS requirement applies to condominium associations with a building that is 3 stories or more in height, regardless of when the building was built [1]. Height is measured under DBPR's guidance, and single-family homes, duplexes, and buildings under three habitable stories are exempt from SIRS (though they may still owe a milestone inspection depending on local rules and building type). This is a condo-specific statute. Cooperative associations got the same SIRS requirement added by later legislation, but standard HOAs governing detached single-family homes are not covered by section 718.112. If your association is a homeowners' association with townhomes or attached units, check whether your community is legally a condominium (many attached-home communities in Florida actually are) because that changes everything about which statute applies. There's no exemption anymore for small associations or for buildings that "look fine." The 2022 and 2023 legislative changes (SB 4-D and SB 154) closed the loophole that let boards vote to waive or reduce reserves for these specific components [2]. You can still underfund reserves for a repaved parking lot or a new pool heater. You cannot underfund the roof, structure, or plumbing lines identified in the SIRS.
What is a reserve study (and how is it different from a SIRS)?
A reserve study is a broader financial planning document that looks at all of an association's major common-area components (roofs, paving, painting, pools, elevators, and more), estimates their remaining life and replacement cost, and calculates how much the association should be saving each year to pay for those replacements without a special assessment. Reserve studies have existed in Florida condo law for decades, long before SIRS became mandatory. A SIRS is narrower and stricter. It only covers the structural and life-safety items listed in section 718.112(2)(g), it must be updated at least every 10 years, and the board loses the ability to waive funding on those specific items [1]. Think of SIRS as a mandatory subset carved out of the old voluntary reserve study system. In practice, many associations get both done at once, often by the same reserve study firm, because it's more efficient to inspect the building once and produce two coordinated reports. If you want the fuller picture on how reserve studies work for Florida condos generally, see our guide on reserve study for condo association.
What is a reserve study for an HOA, and does SIRS apply to HOAs?
For a homeowners' association (governing detached single-family homes, not a condominium form of ownership), a reserve study is a voluntary or governing-document-driven financial study, not a state-mandated SIRS. Florida's SIRS statute (718.112) applies to condominiums and, per later amendments, cooperatives. Traditional HOAs are governed by chapter 720, which does not currently impose a SIRS requirement. That said, plenty of HOA-governed communities have condo-style buildings, townhome buildings over 3 stories held in condo form, or mixed structures, so the label "HOA" on your community's marketing materials doesn't settle the legal question. Check your declaration and ask your association's attorney whether your community is legally organized as a condominium under chapter 718 or as a homeowners' association under chapter 720. That answer determines whether SIRS applies at all. For HOAs that aren't legally condos, a reserve study is still smart practice and some lenders (particularly for FHA and Fannie Mae condo project approvals) require one. See hoa reserve study for how that process works outside the SIRS framework.
When is the SIRS deadline, and how does it connect to milestone inspections?
Most existing condominiums needed to complete their first SIRS by December 31, 2024 [1]. That deadline was tied to the original SB 4-D timeline passed after the Surfside collapse in 2021, though the legislature adjusted some details in 2023 and 2024 sessions, so exact phase-in language has shifted. After the first SIRS, the statute requires an update at least once every 10 years [1]. Many associations choose to time their SIRS update to coincide with their milestone inspection, which is required at 30 years after the certificate of occupancy (25 years if within 3 miles of the coast), and every 10 years after that under section 553.899 [3]. Doing both studies around the same site visit saves engineering fees and gives the board one coherent compliance calendar instead of two separate ones. Don't assume your building's deadline matches a neighbor's. Milestone inspection timing depends on your certificate of occupancy date and your distance from the coast, and DBPR and your local building official are the authorities on your specific trigger date. Confirm your building's exact milestone and SIRS deadlines with your association's counsel and your county building department; don't rely on a generic date you saw online.
How much does a SIRS cost?
There's no single official fee schedule for SIRS. Costs vary by building size, number of components inspected, accessibility (a 40-unit low-rise costs a lot less to study than a 300-unit high-rise), and which firm you hire. Trade groups and reserve study firms have published rough ranges suggesting a few thousand dollars for a small building up to tens of thousands for a large, complex high-rise, but nobody maintains authoritative statewide pricing data, and boards should get at least two or three quotes from licensed firms rather than trusting a single number found online. The engineer or architect doing the visual inspection has to be licensed in Florida, and DBPR maintains license verification for architects and engineers. Some reserve study companies pair a licensed engineer with a reserve specialist to produce the combined SIRS-plus-reserve-study package boards actually need for budgeting. A cheaper quote isn't automatically a bad idea, and an expensive one isn't automatically thorough. Ask what components they're physically inspecting versus estimating from building plans, and ask for a sample report before you sign.
What is a reserve study for HOA (again) and how much should reserves actually be?
How much should an HOA (or condo association) have in reserves? There's no flat statewide dollar figure or percentage the law requires for reserves in general, and that surprises a lot of new board members. What the SIRS statute requires is fully funding the specific structural components it lists, based on their calculated remaining useful life and replacement cost [1]. For everything else (landscaping, pools, clubhouse furniture) associations set their own reserve policy, subject to their bylaws and to the general reserve disclosure and funding rules in section 718.112(2)(f). A reserve study is the tool that answers the "how much" question for your specific building. It's a formula, not a guess: (replacement cost minus current reserve balance) divided by remaining useful life, summed across every component, gives you the annual contribution needed to avoid a special assessment. Buildings that skip this exercise, or that rely on outdated studies, are the ones that get hit with $20,000 to $50,000+ per-unit special assessments when a roof or plumbing system fails years earlier than expected. As a rough industry rule of thumb, some reserve professionals suggest funding reserves at 70% or higher of the "fully funded" level to avoid special assessments, but that's a general reserve-planning heuristic from the industry, not a Florida statutory threshold, and boards should treat it as a planning target rather than a legal minimum.
What is an HOA assessment (and what are HOA special assessments)?
An HOA assessment is the regular fee, monthly, quarterly, or annual, that a community association charges every owner to cover operating costs and reserve contributions. A special assessment is a separate, one-time (or occasionally installment) charge levied when the regular assessment and existing reserves aren't enough to cover an unexpected or large expense, like a mandatory milestone-inspection repair or a SIRS-driven roof replacement. Boards typically need a vote (board-only in many cases, though some declarations require membership approval above a certain dollar threshold) to levy a special assessment, and the specific approval process comes from your declaration, not from chapter 718 directly. Section 718.112(2)(g) does clarify that once SIRS-required reserves are established, the board generally cannot waive or reduce funding for those line items by membership vote, unlike older discretionary reserve items. If your board is staring down a SIRS-driven funding gap, our guide on hoa special assessment walks through the approval process and notice requirements, and condo special assessment insurance covers whether insurance products can help spread the cost.
Are HOA special assessments tax deductible?
Generally, no, not for the individual owner's personal residence. Special assessments for capital improvements (a new roof, new plumbing, structural repairs) are typically treated as an addition to the owner's cost basis in the property, not a deductible expense, under general IRS guidance on capital improvements [4]. That can reduce capital gains tax when you eventually sell, but it isn't a current-year deduction. If the unit is a rental or investment property, some portion of a special assessment tied to repairs (as opposed to capital improvement) may be deductible as a business expense in the year paid, but the repair-versus-improvement distinction is exactly the kind of nuance the IRS scrutinizes, and it depends on facts specific to the work done. This isn't tax advice, and every owner's situation differs by income type, holding period, and property use. Owners should talk to a CPA or tax attorney before assuming any assessment is deductible, and boards should never represent to owners that a special assessment carries a particular tax treatment. That's outside what a board can legally advise on, and getting it wrong creates liability.
What happens if a board ignores the SIRS deadline?
Boards that miss the SIRS deadline expose the association to DBPR complaints, potential fines, and real liability if a structural problem later surfaces that the study would have caught. Section 718.501 gives the Division of Florida Condominiums, Timeshares, and Mobile Homes authority to investigate complaints and take enforcement action against associations that violate chapter 718 requirements [5]. Beyond regulatory risk, there's a practical financial risk that matters more to most boards: without a current SIRS, the association can't legally waive reserve funding for the covered components, meaning the board may already be technically out of compliance with its own budget if it hasn't been collecting the required reserve amounts. That mismatch tends to surface exactly when it's most painful, during a lender's condo questionnaire or a buyer's mortgage underwriting, both of which now often ask directly whether the association has a current SIRS on file. Missing the deadline doesn't mean the building is unsafe. It means the paperwork trail proving the board is managing risk properly has a gap in it, and that gap gets more expensive to explain the longer it sits open.
How do SIRS, milestone inspections, and reserve funding fit together?
| Milestone inspection | s. 553.899 | 30 years after C.O. (25 if within 3 miles of coast) | Every 10 years after | |
|---|---|---|---|---|
| SIRS | s. 718.112(2)(g) | Buildings 3+ stories, most needed one by 12/31/2024 | Every 10 years | |
| General reserve study | s. 718.112(2)(f) | Association discretion / lender requirements | No fixed statutory frequency | The milestone inspection is a structural safety check done by a licensed engineer, focused on visible signs of substantial structural distress. The SIRS is a financial planning document that happens to also require a visual structural inspection, and it feeds directly into the reserve budget. A general reserve study covers everything else that isn't structural. If your engineer is already on-site doing the milestone inspection, it often makes sense to coordinate the SIRS visit at the same time, since florida condo reserve fund relief discusses how legislative adjustments have occasionally shifted deadlines and funding options for associations under financial strain. Managing three separate deadlines, three separate vendor contracts, and three sets of owner disclosures is where boards lose track of things, usually not because they don't care, but because nobody on a volunteer board has bandwidth to track statutory cross-references while also running a monthly meeting. A $199 Building-Specific Board Compliance Kit (see board kit builder) exists specifically to put these deadlines, required disclosures, and vendor scopes on one calendar for your building's age, height, and location, so the board isn't reconstructing the rules from scratch every year. It doesn't replace your engineer or your reserve study firm; it organizes what they produce. |
These are three separate but connected obligations, and boards that treat them as one combined compliance calendar do better than boards that handle each in isolation. | Requirement | Governing statute | Trigger | Frequency |
What should a board do right now to get ahead of SIRS?
Start by confirming your building's exact status: how many stories, when the certificate of occupancy was issued, and whether you're within 3 miles of the coast (all three determine your milestone and SIRS timing). Your county building department and your association's counsel are the right sources for the actual trigger dates, since generic online calculators can be wrong for edge cases like phased construction or annexed buildings. Next, get quotes from at least two or three licensed engineering or reserve study firms, and ask specifically whether their SIRS quote includes the components listed in section 718.112(2)(g) or whether it's a bundled general reserve study that needs to be split out. Ask for their license number and verify it through DBPR's license search. Finally, budget for the reserve funding gap before the study forces your hand. If your last reserve study is more than a few years old, run a rough back-of-envelope estimate now (replacement cost divided by remaining years) so the board isn't blindsided when the official SIRS number comes back. Boards that start this conversation with owners early, well before a special assessment vote, get far less pushback than boards that spring a six-figure number on the community with no warning.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment of an association's major shared components (roofs, paving, plumbing, elevators, and similar systems) that estimates each item's remaining useful life and replacement cost, then calculates the annual savings needed to fund those future replacements without a surprise special assessment.
What is a reserve study for an HOA?
For a homeowners' association, a reserve study serves the same financial planning purpose as it does for a condo: identifying shared assets, estimating their remaining life, and setting a savings target. Unlike SIRS for condos, it's typically not state-mandated for chapter 720 HOAs, though many declarations or lenders require one anyway.
What is a reserve study for HOA and is it required in Florida?
Florida's mandatory SIRS requirement under section 718.112 applies to condominiums, not to homeowners' associations governing detached single-family homes. A traditional HOA reserve study remains largely discretionary under chapter 720 unless the governing documents or a lender requires one.
How much should an HOA have in reserves?
There's no single statewide dollar figure. The right amount depends on a reserve study's component-by-component calculation for your property. Industry professionals sometimes suggest funding to at least 70% of the fully-funded level as a planning target, but that's a heuristic, not a Florida legal requirement, except for SIRS-covered components in condos, which must be fully funded.
What is an HOA assessment?
An HOA assessment is the recurring fee owners pay (monthly, quarterly, or annually) to fund the association's operating budget and reserves. It's distinct from a special assessment, which is a one-time or installment charge levied to cover a specific, often unexpected, expense beyond what regular assessments and reserves can absorb.
How much does a SIRS cost in Florida?
Costs vary widely by building size and complexity, from a few thousand dollars for a small low-rise to tens of thousands for a large high-rise. There's no official statewide fee schedule, so boards should get multiple quotes from licensed engineers or reserve firms and verify licenses through DBPR before hiring.
Are HOA special assessments tax deductible?
Generally not for an owner's personal residence. Special assessments for capital improvements typically add to the owner's cost basis rather than being deductible in the year paid, under general IRS capital improvement guidance. Rental property owners may have different treatment. Owners should consult a CPA for their specific situation.
Which Florida condo buildings must complete a SIRS?
Condominium buildings 3 stories or higher must complete a Structural Integrity Reserve Study under section 718.112(2)(g), regardless of the building's age. Most existing associations needed their first SIRS completed by December 31, 2024, with updates required at least every 10 years after.
Does SIRS apply to HOAs or just condos?
SIRS, as written in section 718.112, applies to condominium associations (and, per later amendments, cooperatives). Standard chapter 720 homeowners' associations for detached single-family homes are not covered, though attached-home communities are sometimes legally condominiums even if marketed as HOAs, so check your declaration.
What components must a SIRS cover?
At minimum: roof, load-bearing walls or primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, windows, and any other component with a deferred maintenance or replacement cost exceeding $10,000 that affects those listed items, per section 718.112(2)(g).
Can a board waive SIRS reserve funding?
No. Once a SIRS identifies required reserve amounts for its covered structural components, the board and membership generally cannot vote to waive or reduce funding for those specific line items, a change from the old rules that allowed broader reserve waivers. Confirm current requirements with your association's attorney, since amendments have adjusted details.
How does SIRS relate to the milestone inspection deadline?
They're separate requirements that often get scheduled together. Milestone inspections (section 553.899) are triggered at 30 years after the certificate of occupancy, or 25 years within 3 miles of the coast, and repeat every 10 years. SIRS is a separate 10-year cycle tied to building height rather than age alone.
