TL;DR
Florida law (Section 718.112, F.S.) requires condo associations 3+ stories to get a Structural Integrity Reserve Study (SIRS) at least every 10 years and fund reserves for the components it covers, no more voting to waive or reduce them. A SIRS typically costs $3,500 to $12,000+ depending on building size, per Florida licensing board guidance and industry surveys.
What is a reserve study?
A reserve study is a professional inspection and financial forecast that tells a condo or HOA board what its shared building components will cost to repair or replace, and when. It combines a physical look at things like the roof, structure, plumbing, and paving with a funding plan showing how much money the association needs to set aside each year so it isn't caught flat-footed when the roof fails in year 18 instead of year 25. In Florida, there are now two overlapping but distinct animals wearing the same rough name. There's the general "reserve study" that any association, condo or HOA, can commission voluntarily to plan reserves for roofs, paint, pavement, and pools. And there's the Structural Integrity Reserve Study (SIRS), a specific, statutorily defined study required for condo buildings three stories or more under Section 718.112, Florida Statutes [1]. A SIRS only covers structural and life-safety components. It does not replace a full reserve study for cosmetic items like landscaping or clubhouse furniture, though many associations bundle both into one engagement to save on inspection fees. If you're a board member trying to figure out which one your building needs, the short answer is: if you're a condo in a building 3 stories or higher, you need a SIRS by law. Everyone else (HOAs, single-family communities, 1-2 story condos) should still want a reserve study as sound financial planning, but it isn't mandated by 718.112. For a broader walkthrough of how reserve studies work outside the SIRS context, see our reserve study guide.
What is a reserve study for an HOA?
For a homeowners association, a reserve study serves the same core purpose as it does for a condo: it identifies the shared components the HOA owns and maintains (roads, clubhouse, pool, gates, retention ponds, sometimes roofs on attached units) and projects when each will need major repair or replacement, then converts that into an annual funding target. HOAs in Florida are not currently subject to the SIRS requirement in Section 718.112, because that statute applies to condominium associations specifically [1]. Chapter 720, Florida Statutes, which governs homeowners associations, has its own (lighter) reserve rules under Section 720.303, and Florida did not extend the post-Surfside structural inspection mandate to HOAs the way it did to condos [2]. That said, an HOA reserve study is still one of the most useful documents a board can commission, because it protects against the special assessment shock that blindsides so many communities when a $400,000 road resurfacing bill lands with no savings to cover it. Our HOA reserve study page goes deeper on how HOA studies differ from condo SIRS studies, what a typical HOA study covers, and how often to refresh one.
What does Florida's structural reserve study statute actually require?
Section 718.112(2)(g), Florida Statutes, requires condominium associations with buildings three stories or higher to obtain a Structural Integrity Reserve Study at least once every 10 years for each building on the condominium property, and to base reserve funding on the results [1]. The statute lists specific components that must be studied, including but not limited to: roof, load-bearing walls or other primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, and windows [1]. The study has to be performed or supervised by a licensed engineer or architect, per the statute's language requiring a "visual inspection" performed by someone qualified under Florida law [1]. This mirrors the licensing structure the Florida Board of Professional Engineers maintains for engineers who legally can sign off on these reports [3]. Here's the part that changed the financial math for a lot of associations: as of the reserve funding cycle beginning with the December 31, 2024 budget, associations can no longer vote to waive, reduce, or use reserve funds for the SIRS-covered components for anything other than their intended purpose [1]. Before the 2022 and 2023 legislative fixes (SB 4-D and SB 154), boards could get a member vote to underfund or skip reserves entirely. That option is gone for SIRS components. Reserves for non-SIRS items (like landscaping or a clubhouse) can still potentially be waived or reduced by a proper vote, depending on the association's documents, so this is a real distinction to run past counsel. For the milestone inspection side of the post-Surfside reforms, which is a separate structural safety inspection tied to building age rather than reserve funding, see our milestone inspections hub.
What is an HOA assessment?
An HOA assessment is a fee the association charges owners to cover its costs, whether operating expenses or capital repairs. There are two basic types. Regular assessments are the recurring dues, monthly or quarterly, that fund day-to-day operations, insurance, and reserve contributions. Special assessments are one-time (or occasionally installment) charges levied when the association needs money it doesn't have on hand, usually because reserves were underfunded or an unexpected repair popped up. A reserve study is really the tool that determines whether an association needs a special assessment at all. Underfund reserves for a decade and the roof, the pool deck, or the structural repair that a SIRS flags becomes a five- or six-figure special assessment landing on every unit owner at once. Fund reserves properly from a solid study, and that same expense gets spread across 10 or 20 years of manageable dues increases instead. For the mechanics of special assessments in Florida condos specifically, including notice requirements and payment plan rules, see hoa special assessment.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure or percentage that Florida law mandates for "how much" an association should have in reserves overall. What the law requires, at least for condos with SIRS-covered buildings, is that reserves be funded based on the actual study results, meaning the association contributes enough each year to reach full (or at least statutorily adequate) funding for each SIRS component by the time it's projected to need replacement [1]. Industry practitioners often talk in terms of a "percent funded" ratio: the association's current reserve balance divided by the ideal balance if every component were funded exactly on schedule. Reserve specialists commonly cite 70% funded or higher as a reasonably healthy target, though this isn't a Florida statutory threshold, it's an industry rule of thumb used across the reserve-study profession [4]. Florida's statute doesn't set a numeric percent-funded target; it requires funding to track the study's calculated need for SIRS components, full stop. In practice, what actually matters for a board is this: get the SIRS or reserve study done by a licensed professional, then fund at or above what the study recommends for structural items, because the statute now takes away your ability to vote that down. For non-SIRS reserve items, boards still have more flexibility, but underfunding those just moves the pain to a future special assessment.
What are HOA assessments used for, and how does a reserve study change that?
Assessments fund everything from landscaping contracts and management fees to insurance premiums and, critically, the reserve accounts that pay for big-ticket replacements down the road. A reserve study reshapes how assessments get built because it turns a guess ("reserves are probably fine") into a schedule ("the roof needs $180,000 in year 12, so we need to be setting aside roughly $15,000 a year starting now"). Without a study, boards tend to do one of two things: underfund reserves to keep monthly dues low and popular, or overfund defensively because nobody actually knows the real numbers. Both are expensive mistakes in different directions. A completed SIRS or reserve study gives the board (and, honestly, gives owners shopping to buy a unit) a real number to argue about instead of a vibe. For condos, the statute now requires that the SIRS-informed budget be presented to unit owners, and associations have to distribute a summary of the SIRS to owners within 45 days of receiving it and again as part of the annual budget meeting notice [1]. That's a meaningful transparency requirement that didn't exist before the 2022 reforms.
How much does a reserve study cost in Florida?
| Small condo (1 building, under 25 units) | $3,500 to $6,000 | |
|---|---|---|
| Mid-size condo (25 to 100 units) | $6,000 to $12,000 | |
| Large or multi-building condo/HOA (100+ units) | $12,000 to $20,000+ | |
| High-rise coastal condo (3+ stories, ocean exposure) | Often at the higher end, sometimes exceeding $20,000 | These ranges reflect market reporting from Florida engineering and reserve-study firms and vary by region, building complexity, and how many buildings the association has to cover; get your own written quotes rather than budgeting off a guide. |
Costs vary a lot based on building size, number of buildings, and whether you're getting a full reserve study or a SIRS specifically. Rough ranges reported across the Florida engineering and reserve-specialist market run from about $3,500 for a smaller single-building condo up to $12,000-$20,000+ for larger or multi-building associations, with high-rise coastal buildings sometimes running higher due to structural complexity and the number of units requiring interior access for plumbing and electrical inspection. Florida's Board of Professional Engineers licenses the engineers who can legally perform SIRS inspections, and boards should confirm any provider's license status directly through the state's license verification tool before signing a contract [3]. Get at least two or three quotes; pricing in this space isn't standardized and a shockingly high or shockingly low bid both deserve questions. | Building size / type | Typical SIRS or reserve study cost range |
Are HOA special assessments tax deductible?
Generally, no, for individual owners. Special assessments paid to a condo or HOA for capital improvements, structural repairs, or reserve shortfalls are typically treated like capital expenditures on the owner's property, not deductible expenses, under IRS guidance in Publication 530 on tax information for homeowners. The IRS's general position is that HOA assessments, whether regular or special, are considered personal, nondeductible expenses when the property is your primary residence, similar to how the IRS treats HOA dues [5]. There are exceptions worth knowing about. If the unit is a rental property, special assessments for repairs may be deductible as a business expense on Schedule E, and assessments for capital improvements may be added to the property's basis (reducing capital gains tax when you eventually sell) rather than deducted immediately, per IRS Publication 527 on rental property [6]. If part of your home is used for a home office, a portion of assessments may be deductible under home office rules. This isn't tax advice, and the details depend heavily on whether the property is a primary residence, rental, or partial business-use property. Talk to a CPA who handles real estate before assuming either way. IRS Publication 530 and Publication 527 are the right starting points for the actual rules [5][6].
Which buildings actually have to get a SIRS?
The SIRS requirement in Section 718.112, Florida Statutes applies to condominium associations for any building on the condominium property that is three stories or more in height, regardless of the building's age [1]. Height, not age, is the trigger. A brand-new 3-story condo building still needs a SIRS on the same 10-year cycle as a 40-year-old one. This is separate from the milestone inspection requirement in Section 553.899, Florida Statutes, which is triggered by building age (typically 25 or 30 years depending on coastal proximity) rather than by height alone, though the two programs often overlap in the same building and use similar engineering inspections [7]. Boards sometimes confuse the two because both came out of the same 2022 legislative response to the Surfside collapse, and a single engineering firm visit can sometimes gather data for both reports. They are legally distinct requirements with separate statutory triggers, separate deadlines, and separate reporting obligations, so don't assume completing one satisfies the other. Cooperatives (co-ops) three stories or higher are also subject to a parallel SIRS-style structural reserve requirement under Section 719.106, Florida Statutes, which mirrors the condo SIRS rules for cooperative associations . HOAs, timeshares, and non-condo residential communities are not currently covered by the SIRS mandate.
What happens if a board skips or delays the reserve study?
Failure to obtain a required SIRS, or failure to fund reserves in line with it, exposes board members and the association to real risk: potential breach of fiduciary duty claims from owners, difficulty selling units (many lenders and title companies now ask for SIRS status before closing), and in some cases state enforcement action tied to the association's licensing and reporting compliance [3]. Beyond the legal exposure, the practical risk is straightforward. If the study isn't done and the building actually has a structural problem developing, nobody catches it until it's a crisis, which is exactly the failure mode the 2022 legislative reforms were written to close after Surfside. Insurers and mortgage lenders are increasingly asking for SIRS documentation as part of underwriting, so a missing or overdue study can also mean higher premiums or trouble refinancing for owners. Our florida condo reserve fund relief piece covers what limited flexibility, if any, currently exists for associations struggling to meet funding deadlines, and what documentation boards should keep if they're negotiating a phased catch-up plan with owners.
How does a SIRS interact with a milestone inspection?
A milestone inspection is a structural safety inspection required under Section 553.899, Florida Statutes for condo and co-op buildings three stories or higher, generally due at 25 years of age (30 years for buildings not within three miles of the coast, though local building officials can adjust this), with a Phase 1 visual inspection and a more invasive Phase 2 if the engineer finds signs of substantial structural deterioration [7]. A SIRS is a financial planning document tied to reserve funding, required every 10 years regardless of building age. They're triggered by different things (age vs. height) and produce different deliverables (a structural safety report vs. a component-by-component funding schedule). Many associations hire the same engineering firm to conduct both inspections close together to save on site visit costs, and it's a genuinely reasonable way to reduce inspection fatigue and duplicate site access requests to unit owners. But the reports are not interchangeable, and one doesn't satisfy the legal requirement for the other. Boards managing both deadlines at once often lose track of who needs what document and when. That's the exact organizational problem a $199 one-time Board Compliance Kit is built to solve: it doesn't replace the licensed engineer who does the actual inspection or study, but it organizes your building's specific deadlines, tracks which report covers which requirement, and keeps the owner communication and documentation your board needs to show it's acting in good faith.
Who is qualified to perform a Florida structural reserve study?
The statute requires the SIRS visual inspection portion to be performed by a licensed engineer or licensed architect, consistent with the licensing categories Florida maintains for these professions under Chapter 471 (engineers) and Chapter 481 (architects), Florida Statutes [1]. The financial/reserve-funding calculation portion is sometimes completed by a reserve specialist working alongside the engineer or architect, though the structural inspection itself must be signed off by the licensed professional. Before hiring anyone, verify their license status directly through Florida's online license search, which covers both engineers and architects registered to practice in the state [3]. Ask for their license number up front and check it yourself; don't take a contractor's word for it. This is a five-minute step that protects the board from a much bigger headache if a study later gets challenged as invalid because the signer wasn't actually licensed. For associations weighing bids, ask each candidate directly whether they've completed SIRS reports under the current statutory language (the requirements were updated by SB 154 in 2023), since some older reserve-study templates don't map cleanly onto the newer statutory component list.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment of an association's shared physical components (roof, structure, plumbing, pavement, etc.) that projects remaining useful life and replacement cost, then builds a funding schedule so the association saves enough over time. In Florida, condos 3+ stories need a specific version called a SIRS under Section 718.112, Florida Statutes.
What is a reserve study for an HOA?
For an HOA, a reserve study identifies shared community assets like roads, clubhouses, pools, and retention ponds, then forecasts when each needs major work and how much the HOA should save annually. Florida's SIRS mandate under Chapter 718 applies to condos, not HOAs, but HOA reserve studies remain a strong (if voluntary) financial planning tool.
What is an HOA assessment?
An HOA assessment is a fee charged to owners to fund the association's expenses. Regular assessments cover ongoing operations and reserve contributions; special assessments are one-time or installment charges for unplanned or underfunded major repairs. A solid reserve study reduces reliance on surprise special assessments by planning for costs in advance.
How much should an HOA have in reserves?
Florida law doesn't set one universal dollar or percentage figure for HOAs. For condos with SIRS-covered buildings, reserves must track the study's calculated funding schedule for structural components. Many reserve specialists use 70% funded or higher as a general health benchmark, though that's an industry guideline, not a Florida statutory requirement.
How much does a reserve study cost in Florida?
Costs typically run from about $3,500 for a small single-building condo to $12,000-$20,000+ for larger or multi-building associations and high-rise coastal buildings, based on market reporting from Florida engineering and reserve-study firms. Get multiple written quotes since pricing varies by region and building complexity.
Are HOA special assessments tax deductible?
Generally no for a primary residence; the IRS typically treats HOA assessments as personal, nondeductible expenses, similar to regular HOA dues. Exceptions may apply for rental properties (potential business expense deduction) or capital improvements (added to cost basis). Confirm your specific situation with a CPA.
What is the Florida statute that requires a structural reserve study?
Section 718.112(2)(g), Florida Statutes requires condominium associations with buildings three stories or higher to obtain a Structural Integrity Reserve Study (SIRS) at least every 10 years and to fund reserves for SIRS-covered components based on the study's results, without the option to waive or reduce that funding.
Does the SIRS requirement apply to HOAs?
No. Section 718.112's SIRS mandate applies specifically to condominium associations, not homeowners associations governed by Chapter 720. HOAs are not currently required by Florida law to complete a Structural Integrity Reserve Study, though nothing prevents a board from commissioning a voluntary reserve study for planning purposes.
Can a condo association still vote to waive reserve funding?
Not for SIRS-covered structural components as of the funding cycle starting with the December 31, 2024 budget; Section 718.112 removed that option. Associations may still have some flexibility to waive or reduce reserves for non-SIRS items, depending on their governing documents, but this should be confirmed with the association's counsel.
How is a SIRS different from a milestone inspection?
A milestone inspection (Section 553.899, F.S.) is a structural safety inspection triggered by building age, usually 25 or 30 years. A SIRS (Section 718.112, F.S.) is a reserve-funding study triggered by building height (3+ stories) on a 10-year cycle. They're separate legal requirements even though the same engineer often handles both.
Who can legally perform a Florida SIRS?
The visual inspection portion of a SIRS must be performed by a licensed engineer or licensed architect. Boards should verify any provider's license status through Florida's online license search before signing a contract, since a study signed by an unlicensed individual could later be challenged as invalid.
What happens if my association skips the required reserve study?
Skipping a required SIRS exposes the association and board to fiduciary duty risk, potential state enforcement issues, and practical problems like unit sales stalling because lenders or title companies want SIRS documentation. It also means structural problems could go undetected until they become expensive emergencies.
