TL;DR
Florida condo associations 3+ stories must fund reserves at 100% of a structural reserve study (SIRS) starting with the 2025 fiscal year, per Fla. Stat. 718.112(2)(f). HOAs (non-condo) aren't bound by that statute, but a reserve study, typically $3,000 to $20,000+ depending on building size, still tells you the real number. Waiving or underfunding reserves usually just delays the bill into a special assessment later.
What is a reserve study?
A reserve study is a professional assessment of your building's major components (roof, paving, elevators, plumbing, structural elements) that estimates their remaining useful life and the cost to repair or replace each one. The output is a funding schedule: how much money the association needs to have set aside each year to cover those future costs without a surprise bill. A full reserve study has two parts. The physical analysis is a site inspection that inventories components, estimates remaining life, and prices replacement. The financial analysis compares that schedule against your current reserve balance and contribution rate, then models funding plans (full funding, threshold funding, or baseline funding) to show the board what happens under each one. For Florida condominiums, the study covers a specific, narrower list of items required by statute: roof, load-bearing walls or other primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, elevators, waterproofing and exterior painting, and windows, for buildings three stories or more [1]. That narrower list is what's called a Structural Integrity Reserve Study, or SIRS, and it's distinct from the broader 'everything the association owns' reserve study some HOAs do voluntarily. A reserve study is not the same document as a milestone inspection. The milestone inspection is a structural safety check, done by a licensed architect or engineer, required at 25 or 30 years depending on coastal location under Fla. Stat. 553.899 [2]. SIRS is a funding document. Many boards commission both around the same time because the same engineer visit can inform both, but they answer different questions: is the building safe, versus how much money do we need.
What is a reserve study for an HOA?
For a non-condo HOA (single-family homes, townhomes with individually owned lots), a reserve study covers the common elements the association actually owns and maintains, things like the clubhouse roof, pool, private roads, retaining walls, or a community dock. There's no Florida statute forcing HOAs to commission one or fund it at any specific level, unlike condos. That said, most HOA governing documents and many state guidance sources still recommend one. The logic is identical to a condo's: if you don't know when the pool deck needs resurfacing or the private road needs repaving, you can't budget for it, and the eventual bill lands on owners as a special assessment instead of a planned line item. Florida's HOA statute, chapter 720, requires HOAs with 100+ voting rights or ones falling into certain fiscal thresholds to adopt reserve schedules if the community votes to fund reserves, but it does not mandate the SIRS-style structural study or state-mandated funding levels that apply to condos under 718.112 [3]. In practice this means HOA boards have more discretion, and more room to underfund, than condo boards do post-2022 reform. A reserve study for an HOA typically runs shorter and cheaper than a condo SIRS because it's not chasing structural load calculations, it's inventorying amenities and infrastructure. See our reserve study and hoa reserve study guides for what a typical scope of work covers.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure; it depends entirely on the age, size, and condition of your components. A 10-unit HOA with a small clubhouse might need $50,000 in reserves. A 200-unit coastal condo tower with elevators, a seawall, and a 40-year-old roof might need $3 million or more. The number only means something in the context of a specific component inventory and cost schedule, which is exactly what a reserve study produces. What regulators do give you is a funding standard, not a dollar target. Since the SB 4-D and SB 154 reforms, Florida condo associations 3 stories or higher must fund reserves for the SIRS-covered items at 100% of the amount the study recommends, starting with the fiscal year beginning January 1, 2025 [1]. Boards can no longer vote to waive or reduce that funding for structural components, full stop, even if owners approve it. That's a real change from pre-2022 law, when a majority vote could waive reserves entirely. A commonly cited industry rule of thumb (not a legal standard) is that reserves should sit around 70% funded relative to the ideal schedule to be considered healthy; anything below 30% funded is often flagged by lenders and insurers as a risk signal. Community Associations Institute has published guidance along these lines for years, though there's no single peer-reviewed source pinning that exact percentage, so treat it as an industry convention rather than a hard number [4]. The honest answer for your board: run or update the reserve study, then fund to what it says. Guessing a round number ('let's just keep $100k in reserves') without an actual component study is how boards end up blindsided.
How much does a reserve study cost?
| Small HOA (under 50 units, no structural elements) | $1,500 to $4,000 | |
|---|---|---|
| Mid-size condo (50-150 units, 3+ stories) | $5,000 to $15,000 | |
| Large or high-rise condo (150+ units, complex structural systems) | $10,000 to $30,000+ | |
| SIRS update/refresh (every 10 years per statute) | Often 30-50% of the original study cost | These are industry-reported ranges, not a statutory fee schedule; no state agency sets or caps reserve study pricing. Florida law requires the SIRS to be performed by a licensed engineer or architect, and requires it at least every 10 years after the initial study [1]. DBPR's Division of Florida Condominiums, Timeshares, and Mobile Homes is the state agency that oversees condo association compliance and publishes guidance on these requirements [5]. Compare that $5,000 to $30,000 one-time cost against the alternative: a special assessment to replace a roof or repair structural damage discovered too late can run into the hundreds of thousands or millions for a single building. The study is cheap insurance against a much bigger bill, and against being blindsided at a unit-owner meeting. |

What is an HOA assessment (and what is a special assessment)?
An HOA assessment is simply the recurring fee owners pay to fund the association's budget, covering operating costs (landscaping, insurance, management fees) and reserve contributions. It's usually billed monthly, quarterly, or annually and is set by the board based on the approved budget. A special assessment is a separate, often one-time charge levied on top of regular assessments, usually to cover an unbudgeted or underfunded expense: a roof replacement the reserves didn't cover, storm damage, a lawsuit settlement, or (increasingly, post-Surfside) SIRS and milestone inspection compliance costs. Florida condo law requires that the board provide notice of a meeting where a special assessment will be considered, and the notice must state the purpose and estimated amount [1]. Special assessments are legal and common in Florida, but they're also the symptom of exactly the problem reserve funding is supposed to prevent. A board that fully funds reserves based on a real study rarely needs an emergency special assessment for routine component replacement; special assessments become necessary when reserves were waived, underfunded, or the study wasn't updated as costs (materials, labor, insurance) rose faster than the old estimate. For a deeper walkthrough of how these charges get approved and billed, see our guide on hoa special assessment rules.
Are HOA special assessments tax deductible?
Generally, no, not for a homeowner's personal residence. Special assessments for capital improvements (a new roof, elevator replacement, structural repairs) are treated by the IRS like a capital expenditure. You typically can't deduct them as a current expense; instead, they get added to your cost basis in the property, which can reduce capital gains tax when you eventually sell [6]. There are narrower exceptions. If you rent out the unit as a business or investment property, a portion of the assessment tied to repairs (versus improvements) may be deductible as a business expense in the year paid, and improvement-related assessments get depreciated over time. If the assessment is for a casualty loss related to a federally declared disaster, different casualty-loss rules may apply. This is genuinely a case-by-case tax question that depends on how the assessment is characterized (repair vs. improvement), your ownership type (primary residence vs. rental vs. investment), and current IRS guidance, which changes. IRS Publication 523 covers basis adjustments for home improvements including special assessments for local improvements [6]. Talk to a CPA before assuming either way; this is not tax advice, and the board can't tell you how to treat it on your return.
What's the difference between a reserve study and a SIRS?
A reserve study is the broader, generic financial planning document; a SIRS (Structural Integrity Reserve Study) is Florida's specific, statutorily-defined version required for condo buildings 3 stories or taller. Every SIRS is a type of reserve study, but not every reserve study meets the SIRS requirements. The practical differences matter for compliance. A SIRS must be performed by a licensed engineer or architect and must specifically cover the statutory component list (structure, roof, waterproofing, electrical, plumbing, fireproofing, elevators) [1]. A general reserve study, by contrast, might be done by a reserve study specialist (not necessarily a licensed engineer) and can include non-structural amenities like pools, fitness equipment, or landscaping, which SIRS doesn't cover. Boards sometimes commission both in one engagement: the licensed engineer does the SIRS-required structural inspection, and the same visit (or a separate reserve specialist) rolls in a broader study covering everything else the association owns. That's efficient, but check that the deliverable clearly separates the SIRS components (which have the strict funding mandate) from the rest (which doesn't, under condo law). For more on how the SIRS-specific requirements work, see reserve study for condo association.
Can a board waive or reduce reserve funding?
For the SIRS-covered structural components in a condo 3 stories or taller, no. Since the 2025 fiscal year, Florida law prohibits waiving or reducing reserve funding for those items, even with a unit-owner vote [1]. That's the single biggest change from pre-Surfside law, when owners could vote annually to waive reserves entirely or fund below the recommended level. For everything outside the SIRS list (pools, landscaping, non-structural amenities), and for HOAs governed by chapter 720 rather than 718, the old rules generally still apply: owners can often vote to waive or reduce reserve funding for those items, subject to whatever the governing documents and chapter 720 allow [3]. There's also been legislative back-and-forth since the original SB 4-D deadline. SB 154, passed in 2023, adjusted some deadlines and added limited relief mechanisms, and further tweaks have come through subsequent sessions. Our florida condo reserve fund relief page tracks what relief options, if any, are currently available. Because this area keeps moving, confirm current deadlines and any relief provisions with your association's counsel before assuming last year's rule still applies.
What happens if an association doesn't fund reserves adequately?
Short term, nothing dramatic happens automatically, there's no state inspector showing up to fine an underfunded association on day one. The consequences show up later, and they're usually worse than steady funding would have been. The most common outcome is a special assessment, often large and poorly timed, when a major component (roof, elevator, structural repair) fails or is flagged by a milestone inspection engineer as needing immediate attention. Owners who bought expecting low monthly fees suddenly face a five- or six-figure bill with little notice. Underfunded reserves also affect resale and financing. Fannie Mae and Freddie Mac both tightened condo lending guidelines after the 2021 Surfside collapse, and lenders now scrutinize reserve funding levels, milestone inspection status, and SIRS compliance as part of project eligibility reviews. A building flagged as underreserved or noncompliant can end up on a lender's ineligible list, which makes units harder to sell or refinance, which then depresses unit values, which then makes the eventual special assessment even harder for owners to absorb. For a condo board specifically, failing to have the SIRS completed and reserves funded per the statutory deadline also exposes the board to potential breach-of-fiduciary-duty claims from owners, separate from any DBPR enforcement action. This is where organizing the paperwork trail actually matters: boards that can show they scheduled the SIRS, tracked the deadline, and documented funding decisions have a much stronger position than ones that can't produce a record. A $199 one-time Building-Specific Board Compliance Kit exists for exactly this: it doesn't replace the licensed engineer who performs the SIRS or milestone inspection, but it organizes deadlines, document requests, and owner communications so the board has that record.
How do reserve requirements differ for condos vs. HOAs vs. co-ops?
| Condo, 3+ stories | Fla. Stat. ch. 718 | Yes, every 10 years [1] | No, for SIRS components, as of 2025 fiscal year [1] | |
|---|---|---|---|---|
| Cooperative, 3+ stories | Fla. Stat. ch. 719 | Yes, similar requirement extended | No, for SIRS components | |
| HOA | Fla. Stat. ch. 720 | No state mandate | Generally yes, subject to governing docs [3] | If your community is a mixed-use or unusual structure (say, an HOA that technically owns a 3-story clubhouse building), don't assume which statute applies just from the name on your documents. Confirm with your association's counsel which chapter actually governs your reserve obligations, since the difference changes both your legal exposure and your funding math substantially. |
Florida condominiums (chapter 718) have the strictest requirements: mandatory SIRS every 10 years for buildings 3+ stories, no waiver of structural reserve funding, and DBPR oversight [1] [5]. HOAs (chapter 720) have much lighter statutory requirements: reserve studies aren't mandated by state law, and funding can generally still be waived by owner vote unless the governing documents say otherwise [3]. Cooperatives (chapter 719) largely mirror the condo reserve and inspection requirements, since the 2022-2023 reforms extended similar SIRS and structural obligations to co-op buildings meeting the height and age thresholds. | Association type | Governing statute | SIRS required? | Reserve waiver allowed? |
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment that inventories a building's major components (roof, elevators, plumbing, structure), estimates each one's remaining life and replacement cost, and produces a funding schedule showing how much the association should save each year. Florida's condo-specific version, the SIRS, covers a defined list of structural items under Fla. Stat. 718.112 [1].
What is a reserve study for an HOA?
For a non-condo HOA, a reserve study covers the common elements the association owns, like a clubhouse, pool, or private roads, and estimates the future replacement cost of each. Unlike condos, Florida HOAs (chapter 720) aren't statutorily required to commission one, though many governing documents recommend it as basic financial planning.
How much should an HOA have in reserves?
There's no fixed dollar figure; it depends on your components' age, condition, and replacement cost, which only a reserve study can tell you accurately. Industry convention treats reserves funded around 70% of the ideal schedule as healthy, with under 30% often flagged as risky by lenders, though these are conventions, not legal standards.
How much does a reserve study cost?
Small HOAs without structural components often pay $1,500 to $4,000. Mid-size Florida condos (50-150 units, 3+ stories) typically pay $5,000 to $15,000 for a full SIRS. Large or complex high-rises can run $10,000 to $30,000 or more. These are market-reported ranges; no state fee schedule sets the price.
What is an HOA assessment?
An HOA assessment is the regular fee (monthly, quarterly, or annual) owners pay to fund the association's operating budget and reserve contributions. It's set by the board based on the approved annual budget and is separate from a special assessment, which is a one-time or extraordinary charge for unbudgeted costs.
Are HOA special assessments tax deductible?
Generally no for a personal residence; special assessments for capital improvements typically get added to your cost basis instead of being deducted, per IRS guidance on home improvements [7]. Rental or investment property owners may have different, narrower deduction options. Confirm treatment with a CPA since it depends on how the assessment is characterized.
What is the difference between a reserve study and a SIRS?
A reserve study is the general financial planning document covering whatever components an association owns. A SIRS (Structural Integrity Reserve Study) is Florida's specific, statutorily required version for condos 3+ stories, covering a defined structural component list and performed by a licensed engineer or architect [1]. Every SIRS is a reserve study; not every reserve study is a SIRS.
Can a Florida condo board still waive reserve funding?
Not for SIRS-covered structural components in buildings 3+ stories, starting with the fiscal year beginning January 1, 2025 [1]. Owners can no longer vote to waive or reduce that funding. Non-structural reserve items and HOA reserves under chapter 720 may still be waivable depending on governing documents; confirm with counsel.
How often does a SIRS need to be updated?
Florida law requires the SIRS to be performed at least every 10 years after the association's initial study for the building [1]. Some boards commission interim updates sooner if costs, conditions, or a milestone inspection reveal significant changes to a component's condition.
Who is required to perform a reserve study or SIRS in Florida?
A SIRS must be performed by a licensed engineer or architect under Fla. Stat. 718.112(2)(g) [1]. General voluntary reserve studies (for HOAs or non-SIRS components) are often done by reserve study specialists, who aren't necessarily licensed engineers, though some firms employ both.
Does a reserve study replace a milestone inspection?
No. A milestone inspection, required under Fla. Stat. 553.899 at 25 or 30 years depending on coastal proximity, is a structural safety assessment [2]. A reserve study or SIRS is a funding document. Buildings typically need both, and the same engineer visit can sometimes inform both reports.
What happens if an association doesn't fund its reserves?
The most common result is a large, poorly-timed special assessment when a major component fails or an inspection flags urgent repairs. Underfunded reserves also affect resale value and mortgage financing, since Fannie Mae and Freddie Mac now review reserve funding and SIRS/milestone compliance as part of condo project eligibility.
