Reserve fund best practices every Florida condo board needs

Last updated 2026-07-24

What is a reserve fund and why does Florida require one now?

A reserve fund is a separate pot of association money set aside specifically for big-ticket repairs and replacements, roof, painting, paving, structural components, elevators, plumbing, and the like. It's different from your operating budget, which pays the electric bill and the landscaper. Reserves pay for the stuff that breaks every 15, 20, or 40 years, the stuff that bankrupts an association if nobody planned for it. Florida changed the rules dramatically after the Champlain Towers South collapse in Surfside in June 2021, which killed 98 people. The legislature passed SB 4-D in 2022 and later refined it with SB 154 in 2023. Together these created two mandates that now define reserve planning for condos three stories or taller: milestone inspections and Structural Integrity Reserve Studies (SIRS). Under Fla. Stat. § 718.112(2)(f), condo associations must now fund reserves for certain "structural" components (roof, load-bearing walls, floor, foundation, fireproofing, plumbing, electrical, waterproofing, exterior painting, windows, and doors, among others) at the full amount identified in the SIRS, with no more voting to waive or reduce that funding. That waiver option, which many boards used for decades to keep dues artificially low, is gone for these specific components starting with the fiscal year that begins January 1, 2025 ^[1]. This isn't optional guidance. It's statute. If your building is three stories or more and not a single-family, two-family, or three-family dwelling, you're in scope ^[2].

What is a reserve study?

A reserve study is a professional assessment of an association's major shared components: what they are, what condition they're in, how long they'll last, and what it will cost to repair or replace them. Good reserve studies produce a schedule (a funding plan spread over years) so the board isn't guessing at how much to collect each month. A basic reserve study has two parts. The physical analysis inventories the components (roof, pavement, pool, elevators, structural systems) and estimates useful life and remaining life for each. The financial analysis then models different funding strategies (usually "full funding" versus "threshold funding" versus "baseline funding") and shows how each affects the fund balance over a 20- or 30-year projection. For Florida condos subject to the SIRS requirement, the study has to go further. It must be performed by a licensed engineer or architect, and it must specifically assess the structural integrity of load-bearing components under Fla. Stat. § 718.112(2)(g) ^[1]. That's a narrower, more technical document than the general reserve studies HOAs have used for years, and it can only be done by someone licensed to do it, not the board treasurer with a spreadsheet. For a broader walkthrough of what goes into one and how boards should read the results, see reserve study.

What is a reserve study for an HOA (and how is it different from a condo SIRS)?

For homeowners' associations (not condos), Florida's SIRS mandate under § 718.112 doesn't apply, because that statute lives in the condominium chapter. HOAs are governed separately under Fla. Stat. ch. 720, which does not currently impose a parallel structural reserve study requirement the way ch. 718 does for condos. That said, plenty of Florida HOAs, especially those with buildings, clubhouses, gated infrastructure, or shared roofs, choose to commission reserve studies voluntarily, because the math doesn't change just because the law doesn't require it. A roof still needs replacing whether a statute mandates a study or not. An HOA reserve study typically follows the same physical-plus-financial-analysis format described above, just without the licensed-engineer mandate SIRS carries. Many HOA boards use a Reserve Study Specialist certified through the Community Associations Institute (CAI), though state law doesn't require any particular credential for a standard (non-SIRS) HOA reserve study. If your HOA governs any structure three stories or more that happens to be organized as a condominium (mixed developments exist), check with your association's counsel about which statute actually governs your entity. Don't assume ch. 720 automatically applies just because you call it an "HOA." See hoa reserve study for the specifics.

How much should an HOA (or condo) have in reserves?

There's no single dollar figure that works for every building, and anyone who gives you a flat number without knowing your components, climate, and age is guessing. The honest answer is: enough to reach 100% of the reserve study's funding recommendation for each component, spread over that component's remaining useful life. A common industry benchmark, used by CAI and reserve specialists nationally, is the "percent funded" ratio: your current reserve balance divided by the fully funded balance the study calculates. Associations under 30% funded are considered "weak" and at elevated risk of special assessments; those in the 70%+ range are considered "strong". Nobody tracks a single authoritative national average consistently, but industry surveys and reserve specialists commonly cite that a large share of associations nationally fall under 70% funded, which is one reason special assessments are so common after a big storm or a structural surprise. For Florida condos under the new SIRS mandate, the question is answered by statute for structural components specifically: you need 100% of what the SIRS says, full stop, no board vote to waive it, starting with fiscal years beginning on or after January 1, 2025 ^[1]. For everything else (paint, landscaping, pool equipment) boards still retain more discretion, though DBPR guidance and prudent practice point the same direction: fund to the study, not to whatever keeps dues flat this year. If your board is worried about the payment shock this creates, look into what temporary relief options exist. See florida condo reserve fund relief for what's changed and what hasn't.

How much does a reserve study cost?

Costs vary widely by building size, complexity, and whether it's a basic HOA-style study or a full SIRS requiring a licensed engineer's structural assessment. Industry pricing for standard reserve studies (the visual, non-structural kind) generally runs from roughly $1,000 to $3,000+ for smaller associations, and can run several thousand dollars more for larger or more complex properties, per pricing ranges commonly cited by reserve study firms and CAI-affiliated specialists. A SIRS, because it requires a licensed engineer or architect to physically inspect structural components, tends to cost more than a basic reserve study, though Florida doesn't publish a statewide fee schedule and prices vary by region, building size, and engineering firm. Boards report costs anywhere from a few thousand dollars for a small building to tens of thousands for a large, complex high-rise. Get at least two or three quotes from licensed firms before signing, and confirm the firm is actually licensed to perform the structural components DBPR requires under § 718.112(2)(g). Think of the study cost as insurance against a much bigger number later. A poorly maintained roof or a deferred structural repair doesn't get cheaper by waiting. It gets more expensive, and it often becomes the special assessment nobody budgeted for.

What are HOA assessments (and what is a special assessment)?

An assessment is simply the fee an association charges its owners to fund shared expenses. Regular assessments (sometimes called dues or maintenance fees) cover the recurring operating budget and reserve contributions. A special assessment is a one-time (or limited-duration) extra charge the board levies when the regular budget and reserves can't cover a specific need, an emergency roof replacement, storm damage not covered by insurance, or a structural repair flagged in a milestone inspection or SIRS. Florida condo boards get their authority to levy special assessments from the association's declaration and bylaws, combined with ch. 718's general framework for budgets and reserves. There's no statutory cap on the size of a special assessment in Florida the way some states impose (check your own declaration, some do set limits), but boards do have to follow notice and meeting procedures, and owners are entitled to see the reasoning behind the charge. Special assessments are exactly what strong reserve funding is meant to prevent, or at least shrink. An association sitting at 100% funded rarely needs a large special assessment for a routine, predictable replacement. One sitting at 20% funded, or one that's been waiving reserves for a decade, often has no other choice when the roof finally fails. For a full breakdown of how these are calculated and challenged, see hoa special assessment.

Are HOA special assessments tax deductible?

Generally, no, not for an owner's personal residence. The IRS treats special assessments the way it treats regular HOA dues: as a personal, nondeductible living expense, similar to paying for home maintenance out of pocket. The IRS's general position on home expenses is outlined in IRS Publication 530, which covers deductible and nondeductible items for homeowners, and HOA fees/assessments for a personal residence are not on the deductible list ^[3]. There are narrow exceptions. If the property is a rental or used for business, a special assessment may be deductible as a business expense or added to the property's cost basis (capital improvement) depending on what the assessment funded, per general IRS rules on rental property expenses ^[4]. If the assessment pays for something that increases the property's value or extends its life (like a new roof), it may need to be capitalized and depreciated rather than deducted immediately, particularly for rental units. This is genuinely a tax question, not a condo-law question, and the answer depends on your filing situation. Confirm with a CPA before assuming either way. Don't take board meeting minutes or a Facebook group's word for what the IRS allows.

How does the SIRS deadline interact with reserve funding decisions?

The Structural Integrity Reserve Study and the reserve funding mandate are two connected but distinct requirements, and boards sometimes conflate them. The SIRS is the study; the funding mandate is what the study forces you to do afterward. Under current Florida law, condo associations three stories or higher had to complete their initial SIRS by December 31, 2024, unless a milestone inspection was already scheduled that would push the timeline, in which case coordination with local building officials matters ^[1]. Once the study is done, the fully-funded reserve requirement for the structural components it covers kicks in with the fiscal year starting January 1, 2025, and there is no more board or membership vote to waive or underfund those specific line items ^[1]. The two obligations feed each other. A milestone inspection (required at 25 years for buildings within 3 miles of the coast, 30 years otherwise, and every 10 years after) often surfaces the exact structural concerns the SIRS then has to price out and schedule funding for. Boards that treat these as separate, disconnected paperwork exercises tend to miss the sequencing, and miss deadlines as a result. For the inspection side of this timeline, see the milestone-inspections hub.

What happens if a board doesn't fund reserves properly?

The immediate risk is a special assessment, often a large one, delivered with little warning when a roof, elevator, or structural component fails ahead of schedule. That's the scenario Florida's post-Surfside reforms were specifically designed to prevent. There's also a legal exposure angle. Board members owe a fiduciary duty to the association, and knowingly underfunding statutorily required reserves, or ignoring a SIRS recommendation without documented rationale, can expose individual board members to liability claims from owners down the line. Florida courts and DBPR have both signaled increased scrutiny of board reserve decisions post-Surfside, though the exact legal contours are still developing case by case. There's a financial exposure angle too, separate from legal risk. Buildings that can't demonstrate adequate reserves or a completed SIRS increasingly struggle to get affordable insurance, and lenders (including Fannie Mae and Freddie Mac, which maintain condo project eligibility reviews) have tightened requirements around reserve adequacy and structural inspection status for condo buildings seeking financing approval. A poorly reserved building can become harder for buyers to finance, which depresses resale values association-wide, more than for the seller trying to close that month. None of this requires panic. It requires a documented process: get the required studies from licensed professionals, put the funding numbers in the budget, and keep records showing the board acted on the professional's recommendation rather than ignoring it.

What should a board actually do with this information?

Start with what the statute requires and work backward. If your condo is three stories or taller, confirm your SIRS is done, confirm it was performed by a properly licensed engineer or architect, and confirm the board has adopted a budget that funds the structural components identified at the 100% level required for fiscal years starting on or after January 1, 2025 ^[1]. Next, separate the mandatory items from the discretionary ones. Structural components under § 718.112(2)(g) have no more waiver option. Non-structural reserve items (landscaping, pool furniture, clubhouse interiors) still allow more board and membership discretion, but "discretionary" doesn't mean "ignore it," it means the board still needs a documented, defensible rationale for whatever funding level it picks. Third, build a communication record. Owners get upset by surprise assessments partly because of the money and partly because they feel blindsided. A board that circulates the reserve study, explains the funding schedule, and documents each budget decision against the study's recommendations gives owners far less to be angry about, even when the number is large. This is the kind of organizational work a $199 one-time Building-Specific Board Compliance Kit is built for: it doesn't replace your engineer or your reserve specialist, but it organizes the deadlines, tracks which studies are done, and keeps the paper trail a board needs if an owner or a DBPR inquiry ever asks "what did you know, and when did you act on it."

How do reserve studies get updated over time?

A reserve study isn't a one-time document. Industry practice, echoed by CAI and most state reserve statutes that address the issue, calls for a full reserve study update (with a site visit) every 3 to 5 years, with a desktop or "no-site-visit" update in the interim years to adjust for inflation, completed projects, and changed conditions. Florida's SIRS requirement builds a version of this into law: associations must have a SIRS performed at least every 10 years under § 718.112(2)(g), following the initial study ^[1]. Many engineers recommend more frequent structural check-ins for older or coastal buildings, since salt air, storm exposure, and age accelerate deterioration in ways a 10-year gap can miss. Between formal updates, a good board tracks completed projects against the study's schedule (did the roof actually get replaced on the year the study assumed?) and adjusts contributions accordingly. A study that was accurate in 2022 can be badly out of date by 2027 if construction costs spiked, a storm caused unplanned damage, or the board deferred a project the study assumed was already funded and scheduled.

How do reserve funding methods actually work (baseline vs. full funding)?

Baseline	Near $0	Lowest	Highest
Threshold	Fixed minimum (e.g., 25%)	Moderate	Moderate
Full funding	100% of fully funded balance	Highest	Lowest

Reserve specialists generally model three funding approaches, and the choice matters a lot for what your monthly assessment looks like. Baseline funding keeps the reserve balance just above zero at its lowest point across the projection period. It's the cheapest month-to-month option and the riskiest, because it leaves no cushion if a cost estimate is wrong or a component fails early. Threshold funding targets a specific minimum balance (say, always staying above $50,000 or above 25% funded) rather than zero. It's a middle-ground approach many HOAs use. Full funding targets 100% of the fully funded balance at all times, meaning the association is essentially keeping pace, dollar for dollar, with the actual depreciation of its components. This is the approach Florida law now mandates for SIRS structural components in condos three stories and up, with no waiver ^[1]. It costs more per month than baseline funding, sometimes substantially more for older buildings catching up from years of underfunding, but it's the version least likely to produce a surprise assessment. | Funding method | Target reserve floor | Monthly cost | Special assessment risk |

Frequently asked questions

What is a reserve study?

A reserve study is a professional evaluation of an association's major shared components (roofs, elevators, structural systems, pavement) that estimates remaining useful life and replacement cost, then models a funding schedule so the association isn't caught short. For Florida condos three stories or higher, the structural version, called a SIRS, must be done by a licensed engineer or architect under Fla. Stat. § 718.112(2)(g).

What is a reserve study for an HOA?

For homeowners' associations under ch. 720, a reserve study works the same way as a condo study functionally (inventory components, estimate life and cost, build a funding plan) but Florida doesn't currently mandate it by statute for HOAs the way it does for condo SIRS under ch. 718. Many HOAs still commission one voluntarily to avoid special assessments.

What is an HOA assessment?

An HOA assessment is the fee charged to owners to fund the association's operating budget and reserves, paid regularly (monthly, quarterly, or annually) per the governing documents. It's distinct from a special assessment, which is an additional, often one-time charge levied when regular funds and reserves can't cover a specific unbudgeted expense.

What is an HOA special assessment?

A special assessment is an extra, non-routine charge an association levies on owners to cover costs the regular budget and reserves don't fully fund, commonly for emergency repairs, storm damage, or structural work flagged by a milestone inspection or SIRS. There's generally no statewide cap in Florida; check your declaration for any specific limits.

How much should an HOA have in reserves?

There's no universal dollar figure; the right amount is whatever the association's reserve study says is needed to reach full funding for each component over its remaining useful life. Industry benchmarks generally consider associations below roughly 30% funded to be at meaningfully higher risk of special assessments, while those above 70% funded are considered financially strong.

How much should a condo have in reserves under Florida law?

For structural components covered by a SIRS, Florida condos three stories or taller must fund reserves at 100% of the study's recommended level starting with fiscal years beginning on or after January 1, 2025, per Fla. Stat. § 718.112(2)(f)-(g). No board or membership vote can waive that requirement for those specific components.

How much does a reserve study cost?

Standard, non-structural reserve studies for smaller associations commonly run roughly $1,000 to $3,000 or more depending on size and complexity. A Structural Integrity Reserve Study (SIRS), which requires a licensed engineer or architect, typically costs more and varies widely by building size and region; get multiple quotes from licensed firms.

Are HOA special assessments tax deductible?

Generally no, for a personal residence, similar to regular HOA dues, per IRS guidance on nondeductible homeowner expenses (IRS Publication 530). Exceptions may apply for rental or business-use property, where an assessment might be deductible as an expense or added to cost basis and depreciated. Confirm with a CPA.

What's the difference between a milestone inspection and a SIRS?

A milestone inspection is a structural safety inspection required at 25 years (within 3 miles of the coast) or 30 years (inland), and every 10 years after, under Fla. Stat. § 553.899. A SIRS is a reserve funding study that prices out structural components and sets mandatory reserve levels under § 718.112(2)(g); the two are related but separate requirements.

Can a condo board still vote to waive reserve funding in Florida?

Not for structural components identified in a required SIRS. Fla. Stat. § 718.112 eliminated the waiver and underfunding option for those specific items starting with fiscal years beginning January 1, 2025. Boards may still retain more discretion over non-structural reserve items, subject to their declaration and prudent fiduciary judgment.

How often does a reserve study need to be updated?

Common industry practice calls for a full update with a site visit every 3 to 5 years, with lighter interim updates in between. Florida's SIRS requirement mandates a new structural study at least every 10 years under § 718.112(2)(g), though older or storm-exposed buildings often benefit from checking sooner.

Who can legally perform a Florida SIRS?

A Structural Integrity Reserve Study must be performed by a licensed engineer or architect, per Fla. Stat. § 718.112(2)(g). A standard, non-structural reserve study doesn't carry the same licensing mandate, though many boards still use CAI-certified Reserve Study Specialists for consistency and credibility.

What happens if a board doesn't fund reserves adequately?

The most common consequence is a large, unplanned special assessment when a component fails ahead of schedule. Beyond that, underfunded reserves can expose board members to fiduciary liability claims, complicate insurance renewal, and make units harder for buyers to finance, since lenders increasingly review reserve adequacy and inspection status before approving condo loans.
