TL;DR
A capital reserve study is a professional assessment of a building's common elements, their remaining useful life, and the cost to repair or replace them. Florida condo associations 3+ stories must fund reserves for items covered by a structural integrity reserve study (SIRS), a specific type of reserve study now required under Fla. Stat. § 718.112. Full studies typically cost $3,000 to $20,000+ depending on building size.
What is a reserve study?
A reserve study is a physical inspection and financial analysis of a building's major common-element components, things like roofs, elevators, plumbing, paving, and building envelope, done to figure out how much money an association needs to set aside now to pay for repairs and replacements later. A good study does two jobs at once: it catalogs what you own and its condition, and it projects a funding plan so the association isn't blindsided by a $2 million roof replacement with $40,000 in the bank. Most studies run 20 to 30 years out. The consultant (often an engineer, reserve specialist, or a firm with both on staff) walks the property, estimates remaining useful life for each component, gets replacement cost estimates, and builds a year-by-year funding schedule. Some studies are "full" studies with on-site visual inspection of every component; others are "update" studies that revise an earlier full study using desktop research and a lighter site visit. In Florida, this general concept got a legal teeth upgrade after the Champlain Towers South collapse in Surfside in 2021. The legislature created a narrower, mandatory version called a structural integrity reserve study (SIRS), which is now required for most condo and cooperative buildings three stories and higher. A SIRS is a reserve study, but not every reserve study is a SIRS. For the full rundown on that distinction, see our reserve study explainer.
What is a SIRS and how is it different from a general reserve study?
A SIRS is the Florida-specific, statutorily defined structural integrity reserve study. It looks only at a fixed list of structural and life-safety components, not the whole property. Fla. Stat. § 718.103(29) defines it as "a study of the reserve funds required for future major repairs and replacement of the common areas based on a visual inspection of the reserve components." [1] Under § 718.112(2)(g), the SIRS must cover 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 exterior doors, 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 licensed engineer or architect performing the visual inspection." [1] A general reserve study, by contrast, can (and usually does) include things like paint, pools, landscaping, and parking lot resurfacing, non-structural items that matter for budgeting but aren't safety-critical. Boards often need both: a SIRS to satisfy the statute and avoid the reserve waiver ban, and a fuller reserve study to plan for everything else the association owns. Our hoa reserve study page walks through how associations blend the two.
Which buildings must get a SIRS, and by when?
The SIRS requirement applies to condominium and cooperative associations with buildings that are three stories or more in height, per § 718.103(29) and § 718.112. The Milestone Inspection deadline and the SIRS deadline run on related but separate clocks, so don't assume finishing one satisfies the other. The statutory deadline for the first SIRS was December 31, 2024, for most existing buildings [1]. Some associations got informal extensions or grace periods through DBPR guidance and later legislative tweaks (including HB 1021 in 2024), so if your association missed the original date, don't guess: confirm your specific deadline and any extension eligibility with your association's counsel and your county building department. The Florida Division of Condominiums, Timeshares, and Mobile Homes at DBPR publishes updated guidance and FAQs on SIRS and milestone requirements. After the first SIRS, the statute requires a new one every 10 years [1]. Boards that treat this as a one-time checkbox instead of a recurring obligation tend to get caught flat when the second cycle comes due.
What does a reserve study cost?
| Reserve study update (desktop) | $1,500 - $4,000 | Reserve specialist | |
|---|---|---|---|
| Full reserve study (non-SIRS) | $3,000 - $10,000 | Reserve specialist / engineer | |
| SIRS (structural components only) | $5,000 - $20,000+ | Licensed engineer or architect | |
| Milestone inspection (Phase 1) | $3,000 - $15,000+ | Licensed engineer or architect | These are planning ranges, not quotes. Get at least two or three proposals; pricing varies a lot by region and by firm backlog, especially post-Surfside when demand for licensed engineers spiked statewide. |
Cost depends heavily on building size, number of components, and whether you're doing a full study or an update. For a typical mid-size Florida condo (50 to 150 units, one or two buildings), expect a range of roughly $3,000 to $10,000 for a standard reserve study, and $8,000 to $20,000 or more for a full SIRS that requires a licensed engineer's visual inspection of structural components, per DBPR guidance and industry pricing patterns reported by reserve study firms and community association trade groups. Larger high-rises, buildings with complex structural systems (post-tensioned concrete, for example), or properties needing destructive testing to assess concrete condition can run well past $20,000. Some engineering firms bundle the milestone inspection and SIRS into one engagement since they overlap in scope (structural components, visual assessment) and that can save money versus hiring two separate firms. Here's a rough cost comparison boards use to budget: | Study type | Typical cost range | Who performs it |
How much should an HOA or condo have in reserves?
There's no single dollar figure that's right for every association; it depends on your components, their age, and their replacement costs. The honest answer is: enough to fully fund your reserve schedule, which the SIRS or reserve study calculates for you, component by component. What we can say concretely: as of the reserve funding rules tied to SIRS, condo associations subject to § 718.112(2)(f) can no longer vote to waive or reduce reserve funding for the components covered by a SIRS, once that SIRS has been completed [1]. That's a major shift from pre-Surfside practice, when many associations voted year after year to underfund or skip reserves entirely to keep monthly assessments low. A common industry benchmark, though not a Florida legal standard, is the "percent funded" metric used by reserve professionals: the ratio of actual reserve cash on hand to the ideal accumulated reserve at that point in the component's life. Reserve professionals commonly describe associations under roughly 70% funded as being in a caution zone, a benchmark drawn from national reserve-study industry practice rather than a single published dataset [2]. There's no perfect national dataset on this; funding levels vary widely by state, age of housing stock, and whether reserve contributions are mandatory. In Florida post-SIRS, mandatory funding for structural items should push percent-funded numbers up over time, but that only works if boards actually collect and hold the money instead of raiding it for operating shortfalls.
What is an HOA assessment, and how does it differ from a reserve contribution?
An HOA assessment is a mandatory fee the association charges owners to fund its budget, both operating expenses (landscaping, insurance, management fees) and reserve contributions (savings for future big-ticket repairs). Florida law authorizes associations to levy both regular assessments and special assessments; the association's declaration and Fla. Stat. ch. 718 (for condos) or ch. 720 (for HOAs) govern how these get calculated and billed. A regular assessment is the predictable monthly or quarterly bill every owner already expects. A special assessment is a one-time or short-term extra charge, levied when the regular budget and reserves can't cover a specific need, like an unplanned roof failure or a SIRS-driven repair that reserves haven't caught up to yet. If your board is facing one of these, our hoa special assessment guide covers notice requirements and payment plan options in more detail. Reserve contributions are technically part of the regular assessment; they're the slice of your dues that goes into a separate reserve account rather than the operating account. Under § 718.112(2)(f), reserve funds "shall be used only for authorized reserve expenditures unless their use for other purposes is approved in advance by a majority vote" of the association, with new restrictions post-SIRS on which items can even be voted down [1].
What are HOA special assessments used for?
Special assessments cover costs that regular assessments and reserves weren't sized to handle: emergency repairs, insurance deductible gaps after a storm, litigation costs, or a capital project that the reserve study flagged but the association underfunded for years. In condo buildings dealing with SIRS-driven repairs, special assessments have become common because many associations spent decades waiving reserves and now face large one-time bills to catch up. Florida condo associations must follow notice and procedural rules before levying a special assessment; the board typically needs to approve it at a properly noticed board meeting, and owners are entitled to advance written notice of the amount and purpose under § 718.112 and the association's bylaws. Some declarations require a membership vote for larger assessments; check yours, and don't rely on a summary article (including this one) to tell you what your specific documents require. Confirm with your association's counsel. Special assessments tied to storm damage sometimes overlap with insurance claims. If your building carries a master policy, coordinate the assessment timeline with the claims process; our condo special assessment insurance piece covers how those two processes typically interact and where gaps in coverage tend to show up.
Are HOA special assessments tax deductible?
Generally, no, not for the owner's personal federal income tax return, if the assessment funds capital improvements, repairs to common elements, or reserve contributions on a primary residence. The IRS treats these as personal living expenses or capital improvements to your property, similar to how home repairs aren't deductible. There are exceptions worth checking with a tax professional. If the unit is a rental property, special assessments for repairs may be currently deductible as a rental expense, while assessments for capital improvements typically need to be capitalized and depreciated over time, per IRS Publication 527 guidance on rental property expenses and improvements [3]. If a special assessment is tied to a federally declared disaster and you have an uncompensated casualty loss, there may be a narrow casualty-loss deduction path, but the Tax Cuts and Jobs Act significantly limited personal casualty loss deductions from 2018 through 2025 to federally declared disasters only [4]. This is genuinely a "talk to your CPA" situation. The rules differ for primary residence, rental, and mixed-use owners, and get more complicated when an assessment is partly for a deductible casualty loss and partly for a routine capital improvement.
Who is qualified to perform a reserve study or SIRS in Florida?
For a general reserve study, Florida law doesn't require a specific license; many associations hire a reserve study specialist, sometimes credentialed through organizations like the Community Associations Institute, or a CPA/engineering firm that offers reserve analysis services. For a SIRS, the bar is higher and set by statute. Section 718.112(2)(g) requires the visual inspection portion to be performed by a licensed engineer or licensed architect [1]. This is the same category of professional required for milestone inspections under § 553.899, which is why many firms now offer both services together. DBPR maintains licensing lookup tools so boards can verify a professional's license status before signing a contract. Don't let a management company or board member self-certify a SIRS to save money; it has to be the licensed professional, full stop. What a board (or a tool like a compliance kit) can legitimately do is organize the RFP process, track deadlines, keep the resulting report accessible to owners, and translate the findings into a board meeting agenda and a funding plan. That's the administrative half of the job, and it matters, but it's separate from the licensed inspection itself.
How do boards turn a reserve study into an actual funding plan?
The study gives you the numbers; the board still has to build the assessment structure around them. Most boards work through a few concrete steps after the report lands. First, get the report to the whole board and, per Florida's transparency requirements, make sure owners can access it too; SIRS results and related records generally fall under the official records access provisions of § 718.111(12). Second, compare the study's recommended annual reserve contribution against your current budget; the gap between what you're collecting and what the study says you need is the number that drives your next assessment conversation. Third, decide funding method: straight-line (equal contributions over time) versus component/cash-flow funding (contributions vary each year based on which items are coming due). Cash-flow funding tends to be more accurate and is what most professional reserve studies actually produce. Finally, put dates on a calendar: the year for your next SIRS update (10 years out per § 718.112 [1]), the year for your next milestone inspection cycle, and interim check-ins if a hurricane or major event might have changed component condition. A single missed renewal date is how associations end up scrambling for an engineer six months before a legal deadline, paying rush pricing because everyone else waited too. This is the exact gap a board compliance kit is built to close: it doesn't replace the licensed engineer's inspection, but it keeps the deadlines, contractor communications, and owner notices organized so the board isn't reconstructing the timeline from old emails a year later.
What happens if an association skips or delays its reserve study?
The consequences run from financial to legal. Financially, deferring the study just defers information; the roof still needs replacing whether or not you've studied it, and delaying the analysis usually means less time to raise the money gradually instead of through a special assessment. Legally, for condo associations subject to the SIRS mandate, failing to complete the study on schedule can put the board out of compliance with § 718.112 and § 718.103(29), which may expose it to owner complaints, DBPR inquiries, or difficulty at resale (buyers' lenders and title companies increasingly ask for SIRS and milestone status documents before closing). Fannie Mae has added condo project review questions specifically about reserve funding and significant deferred maintenance in the wake of Surfside, which can affect whether units in a building qualify for conventional financing at all. If your association is behind, the fix isn't panic, it's sequencing: get an engineer under contract now, even if the report will land later than the original deadline, and document the board's good-faith effort. Boards that show they're actively working the problem tend to fare much better with owners, lenders, and, if it comes to it, regulators than boards that just went quiet.
Frequently asked questions
What is a reserve study?
A reserve study is a professional inspection and financial analysis of an association's major common-element components (roofs, plumbing, paving, structural systems) that estimates each item's remaining useful life and replacement cost, then builds a funding schedule so the association can save gradually instead of hitting owners with surprise special assessments.
What is a reserve study for an HOA?
For an HOA, a reserve study covers common-area components the association owns and maintains, like roads, pools, clubhouses, and roofing on attached structures. It's the same core methodology as a condo reserve study but scoped to whatever the HOA's governing documents assign as common property, per the association's declaration.
What is an HOA assessment?
An HOA assessment is a mandatory fee the association charges owners under its governing documents and state law (Fla. Stat. ch. 720 for HOAs, ch. 718 for condos) to fund operating costs and reserves. It can be a regular recurring assessment or a one-time special assessment for unbudgeted expenses.
How much should an HOA have in reserves?
There's no single universal dollar figure; the right amount is whatever your reserve study calculates based on your specific components, their age, and replacement costs. Industry professionals often flag associations under roughly 70% funded (actual reserves versus ideal accumulated reserves) as a caution zone, though funding norms vary by state and building age.
How much does a reserve study cost?
A standard reserve study for a mid-size Florida association typically runs $3,000 to $10,000. A full structural integrity reserve study (SIRS), which requires a licensed engineer or architect, often costs $5,000 to $20,000 or more depending on building size and structural complexity.
Are HOA special assessments tax deductible?
Generally no, for a primary residence, since the IRS treats them as personal living or capital expenses. Rental property owners may deduct assessments for repairs and depreciate assessments for capital improvements. Talk to a CPA about your specific situation, especially if the assessment relates to a federally declared disaster.
What's the difference between a reserve study and a SIRS?
A reserve study can cover any common-element component an association owns, including non-structural items like paint and landscaping. A SIRS, defined in Fla. Stat. § 718.103(29), only covers a fixed list of structural and life-safety items and must include a licensed engineer or architect's visual inspection.
Which Florida buildings must complete a SIRS?
Condominium and cooperative buildings three stories or higher must complete a SIRS under Fla. Stat. § 718.112. The original statutory deadline for most existing buildings was December 31, 2024, though some received extensions; confirm your building's specific deadline with your association's counsel.
Can a condo association still waive reserve funding in Florida?
Not for components covered by a completed SIRS. Under § 718.112(2)(f), once a SIRS is done, the association can no longer vote to waive or reduce reserve funding for those structural items. Reserves for non-SIRS items may still be subject to waiver votes, depending on the association's documents.
Who can legally perform a SIRS in Florida?
The visual inspection portion of a SIRS must be performed by a licensed engineer or licensed architect, per Fla. Stat. § 718.112(2)(g). Boards can verify license status through DBPR's licensing lookup tools before signing a contract.
How often does a reserve study or SIRS need to be updated?
Under Florida's SIRS requirement, associations must complete a new SIRS every 10 years after the initial one. General (non-SIRS) reserve studies don't have a statutory renewal schedule, but most reserve professionals recommend a full update every 3 to 5 years, with a desktop update in between.
Does a milestone inspection replace the need for a reserve study?
No. A milestone inspection assesses structural safety at specific age thresholds and is required under Fla. Stat. § 553.899. A reserve study or SIRS is a separate financial and component-condition analysis. Buildings often need both, sometimes bundled with the same engineering firm to save cost.
