TL;DR
A reserve study is an engineer's or specialist's report estimating what your association's roof, pavement, plumbing, and other big-ticket items cost to replace, and when. Florida condos 3+ stories must fund reserves at 100% of that study starting with 2025 budgets under SB 4-D. Studies run $3,000 to $20,000+ depending on building size and structural complexity.
What is a reserve study?
A reserve study is a written report that inventories every major shared component in your building (roof, elevators, pool deck, structural elements, plumbing risers, exterior paint) and estimates two things for each: remaining useful life and replacement cost. A qualified reserve specialist or licensed engineer walks the property, reviews maintenance records, and builds a funding schedule showing how much the association needs to save each year to pay for these items without a surprise special assessment. Think of it as a long-range capital budget, not a maintenance checklist. It doesn't tell you when to fix a leaky faucet. It tells you that the roof has 8 years of life left, will cost $340,000 to replace, and that your reserve account needs roughly $42,500 a year set aside to be ready. In Florida, reserve studies for condos come in two flavors that matter a lot right now. A full or "Level II" study includes a site visit and detailed component analysis. Some associations historically relied on a much cheaper "pooled" estimate or a board member's guess, which is exactly what SB 4-D and the SIRS requirements were written to stop. For the structural components covered by the Structural Integrity Reserve Study (SIRS), Florida law under §718.112 now requires that the study be performed by a licensed engineer or architect, more than a reserve specialist. For a full walkthrough of what a SIRS covers versus a standard reserve study, see our reserve study for condo association guide.
What is a reserve study for an HOA?
For a single-family home HOA (no shared building structure), a reserve study covers common elements like the clubhouse roof, pool, sidewalks, retention ponds, entry gates, and playground equipment. It follows the same format as a condo study: inventory, remaining life, replacement cost, funding plan. The key difference is legal weight. Florida's SIRS and 100% funding mandate in Chapter 718 applies specifically to condominiums with buildings three stories or higher, not to homeowners' associations governed by Chapter 720. HOAs are not required by state statute to get a reserve study or to fully fund reserves, unless the association's own declaration or bylaws say otherwise [1]. That gap is a real problem: an HOA board can legally underfund reserves for decades and then hit residents with a massive special assessment when the roof finally fails. Many HOA boards get a reserve study anyway because lenders, especially those following Fannie Mae condo/HOA project review guidelines, and title companies increasingly want to see one before approving mortgages in the community. If your HOA doesn't have one, get one voluntarily. It's the cheapest insurance against a five-figure special assessment nobody saw coming. Our hoa reserve study page breaks down how HOA studies differ from condo SIRS requirements.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure, because it depends entirely on your building's age, size, and component list. The honest answer is: enough to match 100% of what your reserve study says you need, funded on the schedule the study recommends. For Florida condominiums 3 stories and up, this is no longer optional guidance, it's law. Under the changes made by SB 4-D (2022) and refined by SB 154 (2023), condo associations must fund reserves for the SIRS-covered items (roof, load-bearing walls, primary structural systems, fireproofing, plumbing, electrical, waterproofing, and windows/exterior doors, among others) at 100% starting with the fiscal year beginning January 1, 2025 or later [2]. Waiving or reducing these specific structural reserves by member vote is no longer allowed once a SIRS has been completed, per §718.112(2)(f) [2]. A common industry rule of thumb, cited by reserve specialists and CAI (Community Associations Institute), suggests reserves should be funded to at least 70% of the "fully funded" ideal to avoid the highest risk of special assessments, though 100% is the target most engineers now recommend for Florida coastal buildings given hurricane and structural risk [3]. Given the statutory mandate, Florida condo boards should treat 100% funding of SIRS components as the floor, not an aspiration. For components outside the SIRS list (pools, landscaping, painting, parking lots), Florida law is less prescriptive but still requires reserve accounts to be maintained per the study unless waived by a vote of the membership, per §718.112(2)(f).
What is an HOA assessment (and how is it different from a reserve)?
An HOA or condo assessment is simply the amount owners are billed to fund the association's budget. There are two kinds, and confusing them is where a lot of board conflict starts. A regular assessment is the recurring monthly or quarterly fee every owner pays. Part of that fee typically funds operating expenses (landscaping, insurance, management fees) and part funds reserves (the long-term savings account for big future repairs). A special assessment is a one-time, extra charge levied when the association doesn't have enough saved (through reserves or otherwise) to cover an unexpected or underfunded expense, like a $2 million roof replacement or a milestone inspection repair bill. Special assessments are legal in Florida under both Chapter 718 (condos) and Chapter 720 (HOAs), but the board must generally follow notice requirements in the statute and the association's own declaration [4]. See our full breakdown at hoa special assessment. The entire point of a properly funded reserve is to make special assessments rare. Boards that skip or underfund reserves for years are the ones that end up needing $15,000 to $50,000 per-unit special assessments after a milestone inspection or SIRS turns up major structural work.
How much does a reserve study cost?
| Basic reserve study (no SIRS) | Small HOA, under 20 units, no structural components | $1,500 to $4,000 | |
|---|---|---|---|
| Full reserve study | Mid-size condo, 50-150 units | $4,000 to $10,000 | |
| SIRS (structural, engineer-required) | 3+ story condo, 50-150 units | $8,000 to $20,000+ | |
| SIRS, large or complex building | High-rise, 200+ units, coastal | $15,000 to $40,000+ | These are market estimates gathered from published pricing by Florida-licensed engineering and reserve study firms; no single state agency sets or publishes a fixed fee schedule for reserve studies, so get at least two or three quotes. Cost drivers include the number of structural components inspected, whether destructive testing is needed, building square footage, and how many separate buildings the association owns. DBPR, Florida's Department of Business and Professional Regulation, oversees licensing for community association managers and maintains condominium association records, but it does not set reserve study pricing; it's a private market service performed by licensed engineers, architects, or reserve specialists [5]. Budget for this as a recurring cost too. SIRS reports are good for a limited window before they need updating, and most associations should plan to refresh reserve studies every 3 to 5 years to keep numbers current with real construction costs, which have risen sharply since 2020. |

What are HOA assessments used for, and can the board raise them without a vote?
Regular assessments fund whatever line items are in the annual budget: insurance, utilities, landscaping, management fees, and reserve contributions. The board typically sets the annual budget and the assessment rate, within limits set by the declaration and Chapter 718 or Chapter 720. For condos, §718.112(2)(e) allows the board to adopt the annual budget, but if proposed assessments for a given year exceed 115% of the prior year's assessments (excluding certain reserve and emergency items), owners can petition for a special membership meeting to consider rolling it back [2]. That threshold trips up a lot of boards facing steep reserve catch-up increases after SIRS results come in. Special assessments generally require board approval and proper notice to owners, typically 14 days for condo board meetings addressing budget items under §718.112(2)(c) [2], though the exact vote threshold and notice period depend on your declaration and bylaws. Confirm your specific notice and approval requirements with your association's counsel, since these details vary by governing document and have been amended repeatedly in recent legislative sessions.
Are HOA special assessments tax deductible?
For most owners in a personal residence, no. The IRS treats HOA regular assessments and special assessments as a personal living expense, similar to paying your own home's maintenance, and personal home maintenance and repair costs are not deductible on federal income tax returns [6]. There are two narrow exceptions worth knowing. If you rent out the unit as a rental property, HOA fees and special assessments tied to that rental are generally deductible as a rental expense on Schedule E, prorated for the time it was rented, per IRS Publication 527 . If the special assessment is for a capital improvement (not routine repair) on a home you use for business, a portion may be depreciable rather than immediately deductible, again per IRS guidance on capital improvements versus repairs. Special assessments used to increase your home's cost basis (for example, funding a major structural upgrade) can reduce capital gains tax when you eventually sell, since they add to what the IRS treats as your adjusted basis. That's not a deduction now, but it matters later. Talk to a CPA about your specific situation; this isn't tax advice.
What happens if a Florida condo's reserves aren't fully funded by the deadline?
Boards that don't get reserves to 100% of the SIRS-required funding level by the 2025 fiscal year deadline face a hard choice: raise regular assessments sharply, levy a special assessment, take out a loan, or some combination. There's no statutory grace period built into §718.112 for associations that simply didn't budget for it [2]. Some financial relief has emerged. In 2023 and 2024, Florida lawmakers and some lenders introduced limited flexibility, including the ability for certain associations to obtain loans specifically to fund SIRS-mandated reserves, and legislative discussion continues around further delays or phase-in options for financially stressed associations. Rules here have changed multiple times since 2022 and may change again; check current status with your association's counsel and see our tracking page on florida condo reserve fund relief for the latest. What doesn't change: owners in underfunded buildings should expect either a special assessment, a loan-funded assessment (which still costs owners money, just spread over time with interest), or a sharp jump in monthly dues. Waiting doesn't make the structural repair bill smaller. It usually makes it bigger, since construction costs have outpaced general inflation in most of Florida's coastal metros since 2021.
How does a reserve study connect to milestone inspections and SIRS?
These are three separate but linked requirements, and boards often conflate them. The milestone inspection (§553.899) is a structural safety inspection required for condo and cooperative buildings 3 stories or higher, due at 30 years from certificate of occupancy (25 years if within 3 miles of the coast), then every 10 years after . It answers: is the building structurally sound right now? The SIRS (§718.112) is the reserve funding study specific to condos, covering the structural components list, and determines how much money needs to be saved and when. It answers: what will it cost to keep the building sound over the next 25-30 years, and are we saving enough? A general reserve study covers everything else (pools, paving, painting, amenities) and is the broader financial planning document. Milestone inspection findings often feed directly into the SIRS, since a failed or flagged structural item from the milestone report becomes a funding priority in the reserve schedule. Boards juggling all three timelines, plus annual budget deadlines and owner notice requirements, often lose track of which report feeds which deadline. That's the exact gap a Building-Specific Board Compliance Kit is built to close: it organizes your building's milestone, SIRS, and reserve deadlines by age, height, and coastal zone so nothing slips, for a one-time $199. It doesn't replace your engineer or reserve specialist. It keeps their reports, deadlines, and owner notices in one place.
How do boards actually fund reserves without a huge special assessment?
The math is simpler than it feels. Take the reserve study's recommended annual contribution, divide it into monthly assessments, and start now rather than waiting for the SIRS deadline to force the issue. Boards that phase in increases over 2-3 years, rather than jumping straight to full funding in one budget cycle, tend to get less owner pushback and avoid the 115% rollback petition threshold under §718.112(2)(e) [2]. Some associations use a hybrid approach: modest regular assessment increases plus a bank line of credit specifically for SIRS-mandated capital work, spreading the cost over 5-10 years instead of a single lump-sum special assessment. What doesn't work: waiting until the milestone inspection or SIRS report comes back with bad news and then trying to raise the full amount in one vote. That's when boards get sued by angry owners, when units become unsellable because buyers' lenders won't finance in an underfunded association, and when some owners simply can't pay and go into collections. Front-loading the conversation with owners, even before the numbers are final, tends to produce a better outcome than delivering a surprise bill.
Frequently asked questions
What is a reserve study?
A reserve study is a professional report that inventories a building's major shared components (roof, plumbing, structural systems, elevators), estimates each one's remaining life and replacement cost, and produces a funding schedule showing how much the association should save each year to pay for future repairs without a surprise special assessment.
What is a reserve study for an HOA?
For a homeowners' association, a reserve study covers shared amenities like the clubhouse, pool, roads, and common landscaping rather than a building structure. Florida law doesn't require HOAs (Chapter 720) to get one the way condos must, but many boards get one anyway to avoid underfunded surprises and to satisfy mortgage lenders.
What is an HOA assessment?
An HOA assessment is a fee charged to owners to fund the association's budget. Regular assessments are recurring (monthly or quarterly) and cover operating costs plus reserves. Special assessments are one-time extra charges levied when reserves or the regular budget can't cover an unexpected or underfunded expense.
How much should an HOA have in reserves?
Enough to match 100% of what a current reserve study recommends, funded on that study's schedule. Florida condos 3+ stories must fund SIRS-covered structural items at 100% starting with 2025 budgets under §718.112. HOAs have no statutory minimum, but under-70%-funded reserves carry high special assessment risk per industry guidance.
How much does a reserve study cost?
Basic HOA reserve studies without structural components run roughly $1,500 to $4,000. Full condo reserve studies run $4,000 to $10,000. A structural SIRS, which requires a licensed engineer, typically costs $8,000 to $20,000 or more, rising to $40,000+ for large, complex, or coastal high-rises.
Are HOA special assessments tax deductible?
Generally no, for a personal residence. The IRS treats HOA fees and special assessments as nondeductible personal expenses, similar to home maintenance costs. Exceptions exist for rental properties (deductible as a rental expense on Schedule E) or when the assessment funds a capital improvement that increases your home's cost basis for future capital gains purposes.
What is the difference between a reserve study and a SIRS?
A reserve study covers all major shared components (pools, paving, painting, roofs). A SIRS (Structural Integrity Reserve Study) is a Florida-specific requirement under §718.112 covering only structural components (roof, load-bearing walls, plumbing, electrical, waterproofing), must be done by a licensed engineer or architect, and carries a 100% funding mandate with no waiver option once completed.
Do Florida HOAs have to get a reserve study by law?
No. The SIRS and 100% reserve funding mandate under §718.112 applies to condominiums, not homeowners' associations under Chapter 720. HOAs can choose to get a voluntary reserve study, and many do to satisfy mortgage lenders or avoid underfunded surprises, but state law doesn't require it.
When do Florida condo reserves need to be fully funded?
Condominiums 3 stories or higher must fund SIRS-covered structural reserves at 100% starting with the fiscal year beginning on or after January 1, 2025, under changes made by SB 4-D and SB 154. Waiving these specific reserves by member vote is no longer allowed once a SIRS has been completed.
Can an HOA or condo board raise assessments without a vote?
Boards can generally adopt the annual budget and set assessment rates within the declaration's limits. For condos, if proposed assessments exceed 115% of the prior year's (excluding certain reserve and emergency items), owners can petition for a special meeting to seek a rollback under §718.112(2)(e). Confirm specifics with your association's counsel.
What happens if a condo doesn't fund reserves at 100%?
There's no statutory grace period in §718.112 for associations that miss the funding deadline. Boards typically respond with a special assessment, a reserve-funding loan, or a sharp dues increase. Some limited legislative relief options have appeared since 2022 and may change again, so check current status with counsel.
How is a milestone inspection different from a reserve study?
A milestone inspection under §553.899 checks whether a building 3+ stories is structurally sound right now, due at 30 years (25 near the coast) and every 10 years after. A reserve study or SIRS is a financial planning document estimating future repair costs and required savings, often informed by milestone inspection findings.
