TL;DR
There's no flat dollar figure or percentage that fits every HOA. The right amount is whatever a professional reserve study says you need to fully fund replacement of each major component (roof, paving, painting, and for condos under Florida's SIRS law, structural items) without a special assessment. Most well-run associations target 70%+ funded status, not 100%, but Florida condos now have specific funding mandates under Fla. Stat. § 718.112.
How much should an HOA have in reserves?
The honest answer is: it depends on your buildings, not on a rule of thumb. There's no statute, in Florida or anywhere else, that says an HOA (as opposed to a condo) must keep reserves equal to 10% of its budget or any other fixed ratio. That 10% figure floats around online and it's not grounded in law for homeowner associations. What actually determines the right reserve amount is a reserve study: a component-by-component inventory of everything the association is responsible for (roof, pavement, pool equipment, painting, fencing, and for condos, structural elements), each item's remaining useful life, and its current replacement cost. Add those future costs up, spread them over the years remaining before each item needs replacing, and you get an annual funding target. For Florida condominiums, this is no longer just best practice. Fla. Stat. § 718.112(2)(f) requires condo associations to fund reserves for items identified in a Structural Integrity Reserve Study (SIRS) with no ability to waive or reduce that funding for buildings covered by the law [1]. HOAs (single-family and townhome communities governed by Fla. Stat. ch. 720) don't have this SIRS mandate, but many boards use the same reserve study discipline anyway because the underlying math (things wear out, replacement costs money) doesn't care what kind of association you run. A rough industry benchmark from reserve study professionals: aim for a "percent funded" figure of 70% or higher relative to the fully-funded baseline. Below 30% funded is generally considered a red flag for special assessment risk. These are professional guidelines, not statutory thresholds, so treat them as a planning target, not a compliance line.
What is a reserve study?
A reserve study is a physical and financial analysis of an association's common-area components, done by a qualified professional, that projects when each major item will need repair or replacement and how much that will cost. It results in a funding schedule showing what the association should be contributing to reserves each year. A typical reserve study has two halves. The physical analysis inventories every reserve component (roofs, exterior paint, pavement, pool decks, elevators, structural elements for condos) and estimates useful life and remaining useful life for each. The financial analysis takes that data, layers in current reserve balances and interest assumptions, and produces a multi-year funding plan, usually 20 to 30 years out. Florida law distinguishes a general reserve study from the SIRS required for condominiums three stories and higher. A SIRS specifically must be performed by a licensed engineer or architect and must address a defined list of structural components: roof, load-bearing walls, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, and windows and doors, among others, per Fla. Stat. § 718.112(2)(g) [1]. A general (non-SIRS) reserve study can be done by a reserve specialist without an engineering license, and it typically covers a broader list of cosmetic and mechanical items beyond just structural components. For a fuller walkthrough of what the study document actually contains and how boards use it, see our guide to the reserve study.
What is a reserve study for an HOA?
A reserve study for an HOA works the same way as one for a condo, minus the SIRS structural mandate. HOAs typically own and maintain things like private roads, retention ponds, clubhouses, pools, fencing, gates, and sometimes roofs on attached townhome buildings. A reserve study for an HOA inventories those components and builds a funding plan around them. Florida's ch. 720 (homeowners' association law) doesn't require a reserve study the way ch. 718 now requires SIRS for condos. Under Fla. Stat. § 720.303(6), HOA reserves are only mandatory if the members voted to fund reserves, or if the declaration or bylaws already require it; otherwise the board can choose to waive or underfund reserves each year with member approval [2]. That's a meaningfully different legal posture than condos, where SIRS reserve funding for covered components can't be waived at all. That said, plenty of HOA boards get a study done anyway because it's the only reliable way to know if a $40,000 special assessment is coming in year six or year sixteen. If you're deciding whether your community actually needs one, our HOA reserve study guide walks through when it's worth paying for.
How much does a reserve study cost?
Reserve studies for a typical HOA or small condo run roughly $1,200 to $6,000 depending on the number of components, property size, and whether it's a first-time (Level I, full site visit) study or an update. Larger or high-rise condominiums doing a full Structural Integrity Reserve Study with an engineer can run considerably higher, often into the $10,000 to $30,000+ range depending on building size and complexity, because SIRS requires a licensed engineer or architect to physically inspect the structural components listed in Fla. Stat. § 718.112(2)(g) [1]. Cost variables include: - Number of reserve components (a 40-unit condo with elevators and a garage costs more to study than a 20-home HOA with a single retention pond)
- Whether it's a full study with a site visit versus a desktop update of an existing study
- Whether an engineer's stamp is required (SIRS mandates this; general reserve studies usually don't)
- Geographic location and local professional rates DBPR, Florida's regulator for community associations, doesn't set or publish standardized reserve study pricing, so get at least two or three quotes from licensed reserve specialists or engineers before committing. Ask specifically whether the quote covers a full site inspection or a paper update, because that's the single biggest cost driver.
What is an HOA assessment (and what is a special assessment)?
An HOA assessment is simply a fee the association charges owners to cover its operating and reserve costs. Regular assessments (sometimes called dues) are the recurring monthly, quarterly, or annual charges set out in the budget. A special assessment is a one-time, additional charge levied outside the normal budget cycle, usually because reserves fell short of an unexpected or under-funded cost, like a roof replacement, storm damage, or a SIRS-driven structural repair. Both condo and HOA governing statutes give boards authority to levy assessments, but the process and notice requirements differ by association type and by what the declaration says. For condos, Fla. Stat. ch. 718 governs assessment authority and lien rights; for HOAs, it's ch. 720. Special assessments generally require board approval (and sometimes membership approval, depending on the governing documents) and proper written notice to owners before they take effect. The deeper you underfund reserves, the more likely a special assessment becomes when something breaks or a structural deadline hits. That's really the whole logic loop: reserve study tells you what you'll need, insufficient reserves means the gap gets billed as a special assessment instead. For a full breakdown of how these assessments get calculated and challenged, see hoa special assessment.
How does Florida's SIRS law change reserve funding for condos?
Following the 2021 Surfside condo collapse, Florida passed SB 4-D (2022) and later refinements, creating the Structural Integrity Reserve Study requirement now codified at Fla. Stat. § 718.112(2)(g) and the related funding mandate at § 718.112(2)(f) [1][1]. Condominium buildings three stories or more in height must complete a SIRS, and associations can no longer vote to waive, reduce, or use SIRS reserves for anything other than their designated structural purpose. The practical effect on reserve amounts: condo boards can't stretch out structural funding, defer it year to year, or divert it to cover an operating shortfall the way some historically did with general reserves. The SIRS-designated components (roof, load-bearing walls, floor, foundation, waterproofing, electrical, plumbing, fireproofing, and windows/doors, per statute) must be funded based on the study's findings, full stop. Milestone inspections are a related but separate requirement under Fla. Stat. § 553.899, triggered generally at 30 years of building age (25 years for buildings within three miles of the coast), and often the findings from a milestone inspection feed directly into what a SIRS says needs reserve funding [3]. If your building is approaching either deadline, our reserve study and reserve study for condo association guides go through how the two requirements connect in detail. DBPR has published guidance and FAQs on SIRS and milestone compliance for licensed community association managers and boards, which is worth reading directly if your building falls near either threshold [4].
What percentage funded should an HOA or condo reserve target?
| 70% or higher | Strong; special assessment risk low | |
|---|---|---|
| 30% to 70% | Moderate; monitor closely, plan increases | |
| Below 30% | Weak; special assessment risk elevated | |
| 0% (no reserves) | Highest risk; any major repair becomes a special assessment | These bands are professional guidance, not law. Florida's condo SIRS mandate sidesteps the percent-funded debate entirely for structural components: it just requires funding at whatever level the study says is needed, with no minimum percentage carve-out available. For non-SIRS components and for HOAs generally, boards still have discretion, subject to their declaration, on how aggressively to fund toward 100%. |
Reserve study professionals commonly describe funding health as "percent funded," meaning current reserve balance divided by the fully-funded balance (what you'd have if you'd contributed the ideal amount every year since day one). This isn't a statutory metric in Florida; it's an industry convention used by reserve specialists. Rough bands practitioners use: | Percent funded | General risk level |
Are HOA special assessments tax deductible?
Generally, no, not for the individual owner's personal residence. Special assessments for capital improvements or major repairs to common property are typically treated as a capital expense that adds to your basis in the property, not a deductible expense in the year paid, according to IRS guidance on rental and personal-use property [5]. If the unit is a rental property, some portion of the assessment may be depreciable or deductible as a business expense depending on what it funds; consult a CPA, because the line between a capital improvement and a deductible repair is fact-specific and the IRS treats them very differently. Regular monthly HOA dues also aren't deductible for a personal residence. IRS Publication 530 addresses homeowner association fees directly, noting they generally aren't deductible for a primary or second home used personally [5]. Investment or rental property tax treatment is different and again warrants a tax professional's review, not general guidance from an article like this one.
What happens if an HOA or condo doesn't have enough in reserves?
The short version: the gap doesn't disappear, it gets billed later, usually as a special assessment, often at a worse time than if it had been funded gradually. Roofs don't wait for a board to catch up on savings; they fail on their own schedule. For Florida condos, underfunding SIRS-designated structural components isn't just a financial risk anymore, it can also become a compliance issue given the statutory mandate in Fla. Stat. § 718.112(2)(f) that removes the board's or membership's ability to waive that funding [1]. Boards that ignore or delay commissioning a required SIRS, or that don't budget to the study's findings once completed, are exposing the association (and by extension, every owner) to both special assessment risk and potential statutory noncompliance. For HOAs, the exposure is more purely financial since ch. 720 doesn't mandate a study, but the math is identical: the roof still needs replacing whether or not you saved for it. Lenders and buyers have also gotten more attentive post-Surfside, with mortgage underwriters (including Fannie Mae guidelines for condo project reviews) scrutinizing reserve adequacy and deferred maintenance more closely than they did a decade ago, which can affect resale financing for units in underfunded buildings [6].
How do boards actually set the reserve contribution amount?
The reserve study gives you the number; the board (and often the membership) has to vote it into the budget. The process generally looks like: 1. Commission a reserve study (or SIRS, if the building meets the height and story threshold) from a qualified, licensed professional. 2. Review the funding plan options the study presents, often a "full funding" plan and one or more "threshold" or "baseline" alternatives. 3. Incorporate the chosen annual reserve contribution into the proposed budget. 4. Follow the notice and voting procedures in the declaration and Fla. Stat. ch. 718 or ch. 720, since some reserve waivers or reductions require a membership vote, more than board approval, and SIRS-designated components in condos can't be waived at all. 5. Adjust year to year as the study gets updated (most professionals recommend updating a full study every 5 years, with a desktop update in between). This is where a lot of boards get tripped up, not on the math but on the paperwork trail: documenting the vote, the notice given to owners, and the deadline calendar for SIRS and milestone inspections. A structured system for tracking those dates and generating the required owner notices is exactly what a compliance kit like the $199 Building-Specific Board Compliance Kit is built for; it doesn't replace your engineer or your reserve specialist, but it keeps the deadlines, votes, and notices organized so nothing slips. You can start one at /board-kit-builder.
Where can boards go for help getting reserves right?
Start with a licensed reserve study professional or, for SIRS, a licensed engineer or architect as Fla. Stat. § 718.112(2)(g) requires. DBPR's Division of Florida Condominiums, Timeshares, and Mobile Homes regulates community associations and publishes compliance guidance and licensing lookups for community association managers [4]. Beyond the professionals, boards should also talk to the association's own legal counsel about how the declaration handles reserve waivers, special assessment votes, and notice requirements, since those procedural rules vary building to building and statutes change over time. Confirm the current version of Fla. Stat. § 718.112 and § 720.303 with your association's counsel and county before finalizing a budget or reserve schedule, since the legislature has amended SIRS and reserve rules multiple times since the original 2022 law and further changes are plausible in future sessions. For related deadline tracking, our guides on florida condo reserve fund relief and condo special assessment insurance cover two of the most common follow-up questions boards ask once they've seen their reserve study numbers for the first time.
Frequently asked questions
What is a reserve study?
A reserve study is a professional analysis of an association's major common-area components (roofs, paving, painting, and for condos, structural elements) that estimates each item's remaining useful life and replacement cost, then produces a multi-year funding schedule so the association can save enough to avoid special assessments.
What is a reserve study for an HOA specifically?
It's the same process applied to homeowner-association-owned assets like private roads, ponds, clubhouses, and pools. Unlike condos under Fla. Stat. § 718.112, HOAs aren't required by ch. 720 to get one, but many boards commission a study anyway to avoid getting surprised by a large special assessment.
What is an HOA assessment?
An HOA assessment is a fee charged to owners to fund the association's operating budget and reserves. Regular assessments are recurring dues set in the annual budget; special assessments are one-time charges levied when reserves or the budget can't cover an unexpected or underfunded cost.
How much should an HOA have in reserves?
There's no fixed dollar amount or percentage required by Florida law for HOAs. The correct figure comes from a reserve study that inventories every major component and its replacement cost. Industry professionals often target 70% or more of the fully-funded balance as a healthy benchmark, though this is a guideline, not a statute.
How much does a reserve study cost in Florida?
Typical HOA or small condo reserve studies run roughly $1,200 to $6,000. Full Structural Integrity Reserve Studies (SIRS) for condos, which require a licensed engineer or architect under Fla. Stat. § 718.112(2)(g), often cost more, sometimes $10,000 to $30,000+ for larger buildings, depending on size and component complexity.
Are HOA special assessments tax deductible?
Generally no, for a personal residence. The IRS treats special assessments for capital improvements as additions to your property's basis rather than a deductible expense, per IRS Publication 530 guidance. Rental property treatment can differ; consult a CPA for how a specific assessment applies to your tax situation.
Is a reserve study required by Florida law?
For condominiums covered by SIRS (generally three stories or higher), yes, a Structural Integrity Reserve Study is mandatory under Fla. Stat. § 718.112(2)(g). For HOAs under ch. 720, a reserve study isn't statutorily required, though reserves themselves may become mandatory if members vote to fund them or the declaration requires it.
What's the difference between a reserve study and a milestone inspection?
A milestone inspection under Fla. Stat. § 553.899 is a structural safety inspection triggered by building age (30 years generally, 25 years if within three miles of the coast). A reserve study or SIRS is a financial planning document estimating replacement costs and timelines; milestone inspection findings often feed directly into the SIRS.
Can an HOA or condo waive its reserve requirement?
HOAs under ch. 720 can waive or reduce reserves with a membership vote unless the declaration says otherwise. Condos cannot waive SIRS-designated reserve items at all under Fla. Stat. § 718.112(2)(f); that funding mandate applies regardless of board or membership vote.
What happens if my condo skips its SIRS or underfunds reserves?
The association risks both a compliance problem, since SIRS funding for covered components can't legally be waived under Fla. Stat. § 718.112(2)(f), and a financial one, since deferred structural repairs tend to get more expensive and more urgent over time, often forcing a large special assessment.
Who can perform a reserve study or SIRS in Florida?
A general reserve study can be done by a qualified reserve specialist, sometimes without an engineering license. A Structural Integrity Reserve Study must be performed by a licensed engineer or architect, as required by Fla. Stat. § 718.112(2)(g), because it evaluates load-bearing and structural safety components.
How often should a reserve study be updated?
Most reserve professionals recommend a full study every five years with desktop updates in the interim years to reflect inflation, completed projects, and updated cost estimates. Florida statute doesn't set a universal update interval for general reserve studies, though SIRS timing is tied to milestone inspection cycles.
