TL;DR
A Florida reserve study is an engineer or reserve-specialist analysis of what your building's roof, structure, and systems will cost to repair or replace, and when. Florida law (Fla. Stat. 718.112) requires condo boards to fund reserves for certain items based on either a study or a statutory formula, and buildings 3+ stories now need a separate SIRS report under 553.899.
What is a reserve study?
A reserve study is a written report, usually done by an engineer, reserve specialist, or reserve study firm, that looks at every major shared component in your building (roof, paint, pavement, elevators, plumbing risers, structural elements) and answers three questions: what does it cost to replace, how many years of useful life does it have left, and how much money should the association be setting aside each year so the cash is there when the bill comes due. Think of it as a long-range capital budget, not an inspection report. A milestone inspection or SIRS report tells you whether the building is structurally sound today. A reserve study tells you how to pay for tomorrow's repairs without a surprise special assessment. The two documents work together but they're not the same thing and Florida law treats them separately. Most reserve studies run 20 to 30 years out and get updated every 3 to 5 years, or sooner if something changes (a new roof goes on, a special assessment gets levied, insurance costs spike). Some firms do a full study with a physical site visit and remaining-useful-life estimates for every component; others do a lighter "update" study that adjusts numbers based on inflation and any completed projects. Florida statute doesn't dictate the format, so quality varies a lot by firm.
What is a reserve study for an HOA?
For homeowners' associations (single-family and townhome HOAs governed by Fla. Stat. Chapter 720, not condos under Chapter 718), a reserve study works the same way conceptually: an analysis of shared components like the clubhouse roof, pool equipment, gates, retention ponds, and paved roads, with cost estimates and funding schedules attached. The big difference is the legal requirement. Chapter 720 does not require most HOAs to fund reserves at all unless the declaration or bylaws say so, or unless the developer originally funded them and the membership hasn't voted to waive or reduce them. See Fla. Stat. 720.303(6) for the waiver and funding mechanics. That means a lot of Florida HOAs have zero reserves, by design, because the board (or the developer years ago) never adopted them. That's a real gap for buyers. An HOA with a beautiful clubhouse and no reserve study can hit residents with a $5,000 to $15,000 special assessment the year the roof needs replacing, with no warning. If you're on an HOA board, a voluntary reserve study is one of the cheapest risk-management tools available, even though nobody is forcing you to get one. See hoa-reserve-study for how HOA rules differ from condo rules, and hoa-special-assessment for what happens when reserves run short.
What does Florida law actually require for condo reserves?
For condominiums, Fla. Stat. 718.112(2)(f) is the controlling section. It requires the association's annual budget to include reserve accounts for roof replacement, building painting, pavement resurfacing, and "any other item that has a deferred maintenance expense or replacement cost exceeding $10,000" [1]. The amount funded into each account is based on either a reserve study or a statutory straight-line formula using estimated remaining useful life and estimated replacement cost. Here's the part that changed the landscape after the Surfside collapse: for condominiums that are three stories or more and subject to the Structural Integrity Reserve Study (SIRS) requirement, the law now says reserves for the SIRS-covered components (load-bearing walls, roof, structure, fireproofing, electrical, plumbing, foundation, waterproofing, exterior painting, windows, and any other item over $10,000 identified in the SIRS) can no longer be waived or reduced by a membership vote, starting with the association's first fiscal year that begins after December 31, 2024. The statutory text puts it directly: reserve funding for items "included in a structural integrity reserve study" must be part of the budget "without a vote of the unit owners" [1][1]. That's the single biggest thing many boards misunderstand right now. Before 2022's legislative fixes, associations could vote every year to waive or underfund reserves. For SIRS components, that option is gone. For non-SIRS items (things like a clubhouse HVAC unit or a low-rise building's parking lot resurfacing that don't fall under SIRS), waiver rules still apply depending on building type and age, so this is genuinely a "confirm with your association's counsel" situation because the phase-in details differ by when the SIRS was completed and the association's fiscal year.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure or percentage that Florida law requires condos or HOAs to hold, and anyone who gives you a flat number like "reserves should equal 10% of your budget" is oversimplifying. The right amount depends entirely on what's in the building, how old it is, and how soon big-ticket items come due. The reserve study industry commonly talks about a "percent funded" metric: your current reserve balance divided by the theoretical fully-funded balance for where all your components are in their life cycle. National reserve specialists (Community Associations Institute and various state reserve study firms) generally consider 70% funded or higher "healthy," 30-70% "fair," and under 30% "weak" or at risk of special assessments, though these bands come from industry practice, not Florida statute, and there's no single peer-reviewed study nailing down the "right" threshold. A more useful exercise for a Florida board: take your reserve study's 20-year schedule, find the single largest expense in the next 5 years (usually roof or concrete restoration), and ask whether your current reserve balance plus 5 years of scheduled contributions covers it without borrowing or assessing. If the answer is no, that's your real number, not a percentage benchmark. For SIRS-covered components specifically, the statute doesn't set a target dollar reserve. It requires funding at the level the study or formula calculates, full stop, with no underfunding vote allowed for those line items starting with fiscal years after December 31, 2024 [1].
How much does a reserve study cost in Florida?
| Reserve study (full) | $2,500 to $20,000+ | Reserve specialist / RS firm | |
|---|---|---|---|
| Reserve study (update) | $1,000 to $10,000 | Reserve specialist / RS firm | |
| SIRS (structural) | $10,000 to $30,000+ | Licensed engineer or architect | |
| Milestone inspection | Often $15,000 to $75,000+ (varies widely by size/height) | Licensed engineer or architect | Get quotes from at least three firms and ask each one what "level" of study they're proposing (Level I full study with inspection, Level II update with site visit, Level III update with no site visit are common industry tiers). A cheap quote that skips the site visit on a building that's never had one is a false economy. |
Pricing depends heavily on building size, number of components studied, and whether it's a full study (with site visit and physical inspection) or an update. Based on typical Florida reserve-study-firm and CAI-published pricing ranges, a full reserve study for a mid-size condo (50 to 150 units) commonly runs $2,500 to $8,000. Larger high-rises or buildings with complex mechanical/structural systems can run $10,000 to $20,000 or more. Small HOAs with limited common elements (a gate, a pool, some roads) often pay $1,500 to $4,000. Update studies, done between full studies every 3 to 5 years, typically cost less, often 30% to 60% of a full study's price, since the firm is adjusting existing data rather than re-inspecting every component from scratch. A separate cost that boards frequently confuse with the reserve study is the SIRS itself. The Structural Integrity Reserve Study required under Fla. Stat. 553.899 must be performed by a licensed engineer or architect and focuses narrowly on structural and life-safety components. SIRS pricing tends to track closer to milestone inspection pricing (often $10,000 to $30,000+ depending on building size and complexity) because it requires an engineer's physical assessment, more than a financial projection. Some firms bundle SIRS and reserve study work together since the SIRS findings feed directly into the reserve funding requirement. | Study type | Typical Florida cost range | Who performs it |
What is an HOA/condo assessment, and how is it different from a reserve contribution?
An assessment is any charge the association levies against unit or lot owners to cover association expenses. Regular assessments (sometimes called dues) are the recurring monthly or quarterly charges that fund the operating budget and reserve contributions. A special assessment is a one-time, additional charge levied when the regular budget and reserves can't cover a specific need, usually an unexpected repair, a legal settlement, or a shortfall the reserve study should have prevented. Reserve contributions are just one line item inside your regular assessment. If your reserve study says the roof fund needs $40,000 a year and your building has 100 units, that's roughly $400 per unit per year folded into everyone's regular dues. When a board skips or underfunds that line item for years and then the roof fails, the special assessment that follows is often 10 to 50 times larger than what steady reserve funding would have cost, because now the whole bill lands at once instead of being spread over the useful life of the component. Florida's post-Surfside reforms exist specifically to stop that pattern. If you want more detail on how special assessments get calculated and noticed to owners, see hoa-special-assessment.
Are HOA or condo special assessments tax deductible?
Generally, no, not for the individual owner, and this trips up a lot of people every spring. The IRS treats special assessments for capital improvements (a new roof, structural repairs, elevator replacement) as an addition to your cost basis in the property, not a deductible expense. That means you don't write it off the year you pay it; instead it reduces your taxable gain when you eventually sell, similar to how a home renovation adds to basis. IRS Publication 530, "Tax Information for Homeowners," covers how homeowner association assessments and capital improvements are treated for federal tax purposes [2]. There are narrow exceptions. If part of a special assessment is specifically for operating/maintenance costs rather than capital improvement, or if you rent out the unit and can treat it as a business expense or depreciate it, the tax treatment can differ. If you own a rental unit or the assessment mixes repair and capital-improvement costs, talk to a CPA before assuming either way; this is genuinely one of those areas where a blanket internet answer will be wrong for somebody's specific situation.
How does a reserve study connect to SIRS and milestone inspections?
These are three separate but linked requirements, and Florida boards frequently mix them up because they all got tightened after the Champlain Towers South collapse in Surfside in June 2021. The milestone inspection (Fla. Stat. 553.899) is a one-time structural inspection required for condo and cooperative buildings three stories or more, generally due by the 30th anniversary of the certificate of occupancy (or 25th anniversary for buildings within 3 miles of the coast), and every 10 years after that. It answers: is this building structurally safe right now. See florida-condo-reserve-fund-relief and our milestone inspection guides for the full deadline rules by county. The SIRS (also under 553.899, tied to the same statute as milestone inspections) is a study of the remaining useful life and replacement cost of specific structural and life-safety components: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing, electrical systems, plumbing, waterproofing, exterior painting, and windows/exterior doors. Every condo association with a building 3 stories or higher must have a SIRS completed, with recurring updates every 10 years [3]. The reserve study (funded under 718.112) is the broader financial document covering all reserve components, including but not limited to the SIRS items, plus painting, pavement, and anything else over $10,000. As of fiscal years beginning after December 31, 2024, the reserve amounts tied to SIRS components must be fully funded in the budget with no membership waiver available for those specific line items [1]. In practice: get the milestone inspection and SIRS done by licensed engineers first, since their findings (what's failing, what needs replacing, what it'll cost) become the raw data your reserve study or your board plugs into the funding formula. Skipping straight to a reserve study without a completed SIRS on a building that needs one just means you're guessing at numbers an engineer should be verifying.
Who actually performs a Florida reserve study, and does it need to be licensed?
Unlike the SIRS and milestone inspection, which must be performed by a licensed engineer or architect under 553.899, Florida statute does not require a reserve study to be prepared by any specific licensed professional. Many are prepared by Reserve Specialists (the RS credential from the Community Associations Institute) or by CPAs and management companies with reserve-planning experience. That said, Florida does license and regulate community association managers (CAMs) under Fla. Stat. 468.4334, and the license search tool run by the state's professional licensing system lets you verify whether a CAM's license is active and check for discipline history [4]. If your reserve study firm is also acting as your community association manager, confirm their CAM license is active before you sign a contract. Because there's no state licensing requirement specific to "reserve study preparer," quality control falls on the board. Ask for the firm's methodology (physical inspection vs. desktop review), sample reports from other Florida buildings, and whether they carry errors-and-omissions insurance. A $2,000 report from a firm that never sent anyone to walk the roof isn't worth much.
What happens if a board ignores its reserve study or underfunds reserves?
Short term, nothing visible happens. That's exactly the trap. Reserves are invisible until the year the roof leaks, the elevator fails inspection, or the milestone/SIRS engineer flags something that needs immediate structural work. Longer term, underfunded reserves show up in a few predictable ways: special assessments that catch owners off guard, difficulty selling units because buyers' lenders and Fannie Mae/Freddie Mac condo review guidelines now scrutinize reserve funding levels and SIRS compliance status, rising insurance premiums or reduced coverage options for buildings that can't show adequate reserve funding, and in extreme cases, the kind of deferred-maintenance spiral that contributed to the Surfside disaster. None of that is a legal conclusion about any specific building; it's just the pattern Florida has seen since 2021 and the reason lawmakers removed the reserve waiver option for SIRS components. Boards that get ahead of this generally do three things: get the SIRS and milestone inspection done by a licensed engineer on schedule, get an independent reserve study (or update) every few years rather than relying on old numbers, and actually fund the line items the study recommends instead of voting to waive them where waiver is still legally allowed. If your board is juggling a first SIRS, a milestone inspection deadline, and a reserve study all in the same year (common for buildings hitting the 25 or 30-year mark now), organizing the paperwork, deadlines, and owner communication is its own project. That's the specific gap the $199 Board Compliance Kit is built for: it doesn't replace the engineer or the reserve specialist, but it keeps the deadlines, vendor documents, and owner notices from falling through the cracks while your board manages three overlapping requirements at once.
How do owners find out what their reserve study says?
Florida condo associations must make reserve studies and related financial reports available to unit owners on request, and associations with 25 or more units are subject to additional website posting requirements under Fla. Stat. 718.111(12) and 718.112, including posting certain financial and reserve-related documents where owners can access them [5]. The exact list of what must be posted online (budgets, financial reports, SIRS results in some cases) has been updated multiple times in recent legislative sessions, so check the current text of 718.111 and 718.112 or ask association counsel for the up-to-date posting checklist rather than relying on an older summary. Practically, if you're a unit owner and want to see your building's reserve study, start with the property manager or board secretary and request it in writing citing your right to inspect official records under Chapter 718's records-access provisions. If you're a board member trying to keep owners informed without fielding the same records request forty times, posting the study (or a plain-language summary of it) on your association's website or resident portal heads off a lot of annual-meeting friction.
Frequently asked questions
What is a reserve study?
A reserve study is a report, usually from an engineer or reserve specialist, that lists every major shared building component (roof, paint, pavement, elevators, structure), estimates its remaining useful life and replacement cost, and recommends how much the association should save each year. Florida condo law (Fla. Stat. 718.112) ties reserve funding requirements to either a study or a statutory formula.
What is a reserve study for an HOA?
For HOAs under Chapter 720, a reserve study analyzes shared assets like clubhouses, pools, gates, and roads and projects future repair costs. Unlike condos, most Florida HOAs aren't legally required to fund reserves at all unless their governing documents or a membership vote require it, so a reserve study is often voluntary but still financially smart.
What is an HOA assessment?
An HOA (or condo) assessment is any charge the association levies on owners to pay for shared expenses. Regular assessments fund the operating budget and reserves; special assessments are one-time additional charges for costs the regular budget and reserves can't cover, often a major repair or an underfunded reserve account.
How much should an HOA have in reserves?
There's no fixed statutory dollar amount. Industry benchmarks often cite 70% or higher "percent funded" (current reserves versus the theoretical fully-funded level) as healthy and under 30% as risky, but these are industry norms from groups like CAI, not Florida law. The better question is whether reserves plus 5 years of contributions cover the next major expense in your study.
How much does a Florida reserve study cost?
A full reserve study for a mid-size Florida condo (50-150 units) typically costs $2,500 to $8,000; larger or more complex buildings can run $10,000-$20,000+. Update studies done every 3-5 years usually cost 30-60% of a full study. Small HOAs with limited common elements often pay $1,500 to $4,000.
Are HOA or condo special assessments tax deductible?
Generally no. The IRS treats special assessments for capital improvements as adding to your property's cost basis rather than a deductible expense (see IRS Publication 530). They reduce taxable gain when you sell rather than lowering your taxes the year you pay. Rental property owners should check with a CPA since business-use rules can differ.
Is a reserve study the same as a SIRS?
No. A SIRS (Structural Integrity Reserve Study, Fla. Stat. 553.899) is a narrower, engineer-performed study of specific structural and life-safety components required for condo buildings 3+ stories. A reserve study is the broader financial document covering all reserve items, including SIRS components plus things like painting and pavement.
Does Florida law require condos to get a reserve study?
Florida law requires condo associations to fund certain reserve accounts (Fla. Stat. 718.112(2)(f)), and that funding is based on either a reserve study or a statutory formula. The law doesn't force every association to hire an outside firm for a study, but doing so is generally the more accurate and defensible way to set reserve levels.
Can a condo association waive reserve funding in Florida?
For SIRS-covered structural components, no, not for fiscal years beginning after December 31, 2024; that funding is now mandatory without an owner vote. For non-SIRS reserve items, waiver rules still apply in some cases depending on building type, so confirm current rules with association counsel since this area has changed multiple times since 2022.
How often should a reserve study be updated?
Most Florida reserve specialists recommend a full study every 5 years with a lighter update study every 2-3 years in between, or sooner after a major event like a new roof installation, a special assessment, or a SIRS/milestone inspection that changes cost estimates for structural components.
Who pays for a Florida reserve study?
The association pays, typically out of the operating budget, since the study benefits the whole membership. Costs get spread across all unit or lot owners through regular assessments, the same way most professional service fees (management, legal, accounting) are funded.
What's the difference between a reserve study and a milestone inspection?
A milestone inspection (Fla. Stat. 553.899) is a structural safety check by a licensed engineer, due at 25 or 30 years depending on coastal proximity, then every 10 years. A reserve study is a financial planning document projecting repair costs and funding needs. Milestone/SIRS findings typically feed the numbers used in the reserve study.
