TL;DR
A professional reserve study is a physical inspection and funding analysis of a building's major components (roof, structure, plumbing, paint, pavement, etc.) that estimates remaining life and replacement cost. Florida condos with 3+ habitable stories must get one to satisfy Structural Integrity Reserve Study (SIRS) requirements under F.S. 718.112. Costs typically run $3,000 to $20,000+ depending on building size and complexity.
What is a reserve study?
A reserve study is a two-part analysis: a physical inspection of a building's major shared components, and a financial plan that says how much money the association needs to save each year to pay for replacing those components when they wear out. Think of it as a maintenance forecast married to a savings plan. The physical part usually covers roofs, load-bearing walls, floors, foundations, fireproofing, plumbing, electrical systems, waterproofing, exterior paint, windows, and pavement. A qualified preparer, often an engineer, reserve specialist, or in some cases a licensed contractor, walks the property, reviews maintenance records, and estimates the remaining useful life of each item along with its current replacement cost. The financial part turns those numbers into a funding schedule. It tells the board what the reserve balance should be this year, next year, and ten years from now, so the association isn't blindsided by a $2 million roof replacement with $40,000 in the bank. In Florida, this isn't just good practice anymore for many buildings. Condominiums with three or more habitable stories now face a specific, statutory version of this called a Structural Integrity Reserve Study, or SIRS, under F.S. 718.112 [1]. That's a narrower, structural-focused study than a traditional full reserve study, and the two terms get mixed up constantly. More on that distinction below.
What is a reserve study for an HOA?
For a homeowners association (single-family home HOAs, not condos), a reserve study works the same way conceptually: an inspection of shared components like roads, clubhouses, pools, gates, and irrigation systems, paired with a funding plan. The difference is legal, not mechanical. Florida's SIRS mandate under Chapter 718 applies to condominiums, not standalone HOAs governed by Chapter 720. HOAs are not currently required by state statute to complete a SIRS or even a traditional reserve study, though many governing documents (declarations, bylaws) require reserve funding decisions to be based on one, and lenders sometimes ask for one during refinancing or resale disclosures. That said, plenty of HOA boards commission a reserve study voluntarily because it's the only defensible way to set assessments. Without one, boards are often guessing, and guessing tends to end in either underfunded reserves or a special assessment nobody saw coming. If your community has a clubhouse roof, a private road, or a seawall, you're carrying real replacement risk whether or not a statute forces you to study it. See our related guide on hoa reserve study for a deeper look at HOA-specific funding mechanics and how they differ from condo requirements.
What is a SIRS and how is it different from a regular reserve study?
A Structural Integrity Reserve Study (SIRS) is Florida's narrower, statutorily defined version of a reserve study, created after the 2021 Champlain Towers South collapse in Surfside. It focuses specifically on structural and life-safety components, not the full menu of items a traditional reserve study might cover, like landscaping equipment or a lobby renovation fund. Under F.S. 718.112(2)(g), a SIRS must be based on a visual inspection performed by a licensed engineer or architect and must include, at minimum: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, and windows and exterior doors [1]. The statute states that associations must have a SIRS completed "at least every 10 years after the condominium's creation for each building on the condominium property that is three stories or more in height" [1]. This applies to condo buildings statewide, more than coastal ones, though coastal humidity and salt exposure tend to accelerate wear on exactly the components SIRS targets. Critically, once a SIRS is complete, the board loses the ability to waive or reduce reserve funding for the components it covers. Full funding based on the study becomes mandatory starting with the fiscal year following the study's completion, per the same statute [1]. That's the part that catches boards off guard: the SIRS isn't just a report, it's a funding trigger. For the milestone inspection side of this (the separate structural safety inspection tied to building age), see our milestone inspection coverage.
Who can legally perform a reserve study or SIRS in Florida?
For a SIRS specifically, F.S. 718.112(2)(g) requires the visual inspection portion to be performed by a person qualified to perform such inspections, which the statute points to as a licensed engineer or architect [1]. For a traditional (non-SIRS) reserve study, Florida doesn't mandate a specific license, though the Community Associations Institute (CAI) recommends using a credentialed reserve specialist, and many boards hire firms staffed by engineers anyway since the structural components overlap so heavily with SIRS scope. The Department of Business and Professional Regulation (DBPR) oversees licensing for community association managers and enforces condominium recordkeeping and financial disclosure requirements under Chapter 718, though DBPR itself doesn't license "reserve study providers" as a distinct category [2]. Boards should confirm any firm's engineer or architect license is active through the Florida Board of Professional Engineers or Board of Architecture before signing a contract. Don't let a board member's cousin who does home inspections write your SIRS. It has to be a licensed engineer or architect for the structural components, full stop, and cutting corners here just means redoing it later at your own expense.
How much does a reserve study cost?
| Small condo, single building, under 50 units | $3,000 to $8,000 | |
|---|---|---|
| Mid-size condo, 50-150 units | $6,000 to $15,000 | |
| High-rise or multi-building complex | $10,000 to $25,000+ | |
| Includes destructive concrete testing | Add $5,000 to $20,000+ | These ranges reflect general market reporting from association management and engineering firms; costs are not set by statute and boards should get at least three competitive quotes rather than assuming a number. Ask specifically whether the quote includes both the visual inspection and the funding analysis, since some firms price those separately. Compare this against the cost of skipping it: a special assessment for an unfunded roof or structural repair routinely runs into six or seven figures for a mid-size building. The study is cheap insurance against a much bigger bill later. For more on assessment mechanics, see hoa special assessment. |
Reserve study and SIRS costs vary a lot based on building size, number of buildings, age, and how much existing documentation (permits, prior inspections, maintenance logs) the engineer has to work with. There's no single statutory fee schedule, so pricing is market-driven. Based on typical industry ranges reported by reserve study and engineering firms operating in Florida, a small single-building condo (under 50 units) can expect a SIRS or combined reserve study in the $3,000 to $8,000 range. Larger or multi-building associations, especially high-rises with more complex structural systems, commonly see quotes from $10,000 to $25,000 or more. Coastal high-rises needing destructive testing (core samples, rebar exposure) to assess concrete spalling often land at the higher end or above it. | Building type | Typical study cost range |
How much should an HOA (or condo) have in reserves?
There's no flat dollar figure that fits every building, because reserve needs depend entirely on what components you own, their age, and their replacement cost. That's the whole point of getting a study done instead of picking a round number. That said, the industry benchmark most reserve specialists cite is a "percent funded" ratio: the association's actual reserve balance divided by the fully funded balance the study calculates. CAI and most reserve professionals consider 70% funded or higher to be strong, 30% to 70% is a caution zone, and under 30% is considered weak or at-risk, though these aren't Florida statutory thresholds, they're industry norms. For Florida condos, the more important number now isn't a target percentage, it's a legal floor. Once a SIRS is complete, F.S. 718.112 requires the association to fund reserves for SIRS-covered components at 100% of the amount the study calculates as necessary, with no ability for the membership to vote to waive or underfund those specific line items [1]. Non-SIRS reserve items (things like clubhouse furniture or a pool resurfacing fund) can still be waived or reduced by membership vote in many cases, subject to the details in your governing documents and any recent statutory amendments, so confirm the current rule with your association's counsel. For HOAs under Chapter 720, there's no statewide statutory floor forcing full funding, so the number should come straight from your study's recommended contribution schedule. See reserve study for the general Florida legal framework, or reserve study for condo association for condo-specific detail.
What is an HOA assessment (and how does it relate to reserves)?
An HOA assessment is the regular fee members pay to fund the association's operating budget and reserve accounts. Most associations bill this monthly, quarterly, or annually, and the amount is set by the board (sometimes with membership approval required for large increases, depending on the governing documents). Regular assessments typically fund two buckets: the operating budget (day-to-day expenses like landscaping, insurance, management fees) and the reserve fund (long-term savings for big-ticket replacements identified in the reserve study). A well-run association sets assessments so the reserve contribution matches, or gets close to, what the study recommends each year. When regular assessments aren't enough, usually because reserves were underfunded for years or an unexpected repair pops up, boards turn to a special assessment: a one-time (or sometimes installment) charge on top of the regular assessment to cover a specific cost. Special assessments are legal in Florida but must generally follow notice and voting procedures spelled out in the governing documents and, for condos, in Chapter 718. See hoa special assessment for the notice and approval rules in more detail.
Are HOA special assessments tax deductible?
Generally, no. For an owner who uses the property as a personal residence, special assessments and regular HOA dues are considered a personal, nondeductible living expense by the IRS, similar to how you can't deduct your own home repair costs [3]. There are narrow exceptions. If the unit is a rental property, special assessments and dues may be deductible as an ordinary and necessary rental expense, subject to normal rules about capital improvements versus repairs (a special assessment for a new roof, for example, may need to be capitalized and depreciated rather than deducted all at once) [3] [4]. If part of the assessment funds a casualty-loss repair tied to a federally declared disaster, there may be additional considerations, but this gets complicated fast. This isn't tax advice, and the line between a deductible repair and a capital improvement that must be depreciated is genuinely fact-specific. Owners should talk to a CPA who handles rental or investment property before assuming any assessment is deductible. The IRS's own guidance on rental property expenses is the right starting reference point [4].
What happens if a Florida condo skips or delays its SIRS?
Skipping a required SIRS puts the association out of compliance with F.S. 718.112, which can expose the board to member complaints, potential legal liability, and difficulty with insurance renewal or mortgage underwriting, since more lenders and insurers now ask for SIRS status before writing new policies or loans on a building. The statute ties SIRS timing to milestone inspection deadlines and building age. Buildings need their first milestone inspection, and associations governed by SIRS requirements need to have completed studies, on a schedule keyed to when certificates of occupancy were issued, generally at 25 years for buildings within three miles of the coast and 30 years for others, with SIRS updates required at least every 10 years thereafter [1]. Some counties have adopted earlier or additional local deadlines, so always check with your county building department, more than the state statute. Because statutory deadlines and even the underlying requirements have shifted since the original 2022 post-Surfside reforms (with legislative adjustments in 2023 and 2024), boards should confirm current SIRS timing directly with association counsel rather than relying on any single source, including this one, for a specific compliance date. See our florida condo reserve fund relief coverage for how recent legislative changes have adjusted some of these deadlines and funding rules.
How does a reserve study connect to the milestone inspection?
The milestone inspection and the SIRS are two separate but related requirements, and boards often confuse them because they get triggered around the same building age. The milestone inspection, under F.S. 553.899, is a structural safety inspection performed by a licensed engineer or architect that produces a pass/fail-style report on the building's structural integrity, due at 25 or 30 years depending on coastal proximity, then every 10 years after [5]. Its job is to catch structural problems before they become a Surfside-style failure. The SIRS, by contrast, is a funding document. It uses similar inspection data (and often the same engineer, in the same site visit, to save cost) but its output is a reserve funding schedule, not a pass/fail structural verdict. Many firms bundle both inspections into a single site visit since the engineer is already up on the roof and in the mechanical rooms anyway, which can meaningfully cut the total cost compared to hiring two separate firms. If your building already needs a milestone inspection this cycle, ask your engineering firm for a combined milestone-plus-SIRS quote before assuming you need two separate contracts.
How should a board actually use a reserve study once it's done?
A reserve study sitting in a filing cabinet does nothing. The value comes from turning its recommendations into the annual budget, the reserve line-item schedule, and the board's communication with owners. A few concrete steps that separate boards who use their study well from boards who just check the box: First, adopt the study's recommended funding schedule as the reserve contribution line in next year's budget, not a rounded-down version of it. Second, schedule the follow-up study (SIRS updates are due at least every 10 years, but a lot can change in five, especially after a major storm) rather than waiting for a compliance deadline to force your hand. Third, keep the study, the milestone inspection report, permits, and maintenance records organized in one place so the next board, the next management company, and any buyer's lender can find them fast. That last point sounds obvious but it's where most associations actually fail. Records get scattered across three past management companies, a departed board president's email, and a filing cabinet nobody has the key to. This is the specific gap our $199 Board Compliance Kit is built to close: it doesn't perform the inspection or the study (only a licensed engineer, architect, or reserve professional can do that), but it organizes your building's specific deadlines, schedules the next required study or inspection, and keeps the paper trail in order so your board isn't scrambling six months before a deadline.
What should a board look for when hiring a reserve study firm?
Price matters, but it shouldn't be the only filter. A cheap study that misses a failing waterproofing membrane costs the association far more later than the few thousand dollars saved on the contract. Ask for the engineer's or architect's active license number and verify it directly with the Florida Board of Professional Engineers or Board of Architecture and Interior Design rather than taking the firm's word for it. Ask whether the quote covers both the visual inspection and the financial funding analysis, since some firms split those into two line items or two contracts. Ask for sample reports from similar buildings (same height, similar age, similar coastal exposure) so the board can see the level of detail before committing. And ask directly whether destructive testing (core sampling of concrete, for example) is included or likely to be recommended as an add-on once the visual inspection is underway, since that can shift the final invoice significantly. Get at least three quotes. Reserve study and SIRS pricing varies enough between firms, and the report quality varies enough too, that a single quote tells a board almost nothing about whether it's getting a fair deal.
Frequently asked questions
What is a reserve study?
A reserve study is a physical inspection of a building's major shared components (roof, plumbing, structure, paint, pavement, etc.) combined with a financial plan estimating how much an association needs to save each year to replace those components. In Florida, condo buildings with 3+ habitable stories need a specific version called a SIRS under F.S. 718.112.
What is a reserve study for an HOA?
For a single-family home HOA, a reserve study inspects shared amenities like roads, clubhouses, and pools, then produces a funding schedule for replacing them. Unlike condos, standalone HOAs under Chapter 720 aren't currently required by Florida statute to complete one, though governing documents or lenders often require it anyway.
What is an HOA assessment?
An HOA assessment is the regular fee (monthly, quarterly, or annual) members pay to fund the association's operating budget and reserve savings. When regular assessments can't cover a large or unexpected cost, boards can levy a special assessment, a one-time or installment charge on top of normal dues.
How much should an HOA have in reserves?
There's no single dollar figure; it depends on the components the association owns and their replacement cost, per the reserve study. Industry professionals generally consider a reserve fund 70% or more "funded" (actual balance versus fully funded target) to be strong, and under 30% funded to be a risk zone, though these are industry norms, not Florida statutory thresholds.
How much does a reserve study cost in Florida?
Costs typically range from $3,000 to $8,000 for a small single-building condo under 50 units, up to $10,000 to $25,000 or more for larger high-rises or multi-building complexes. Destructive concrete testing, when needed, can add $5,000 to $20,000 or more. Get at least three quotes since pricing isn't standardized by statute.
Are HOA special assessments tax deductible?
Generally no, for an owner's personal residence, special assessments are a nondeductible personal expense, similar to home repairs. If the unit is a rental property, the assessment may be deductible as a rental expense or may need to be capitalized and depreciated, depending on whether it's a repair or capital improvement. Consult a CPA.
What is a SIRS and how is it different from a regular reserve study?
A Structural Integrity Reserve Study (SIRS) is Florida's statutory version of a reserve study, required for condo buildings 3+ stories under F.S. 718.112. It covers specific structural and life-safety components (roof, load-bearing walls, plumbing, waterproofing, etc.) and, once completed, makes full reserve funding for those items mandatory with no waiver option.
Who is legally allowed to perform a Florida SIRS?
The visual inspection portion of a SIRS must be performed by a licensed engineer or architect, per F.S. 718.112(2)(g). Boards should verify the individual's license directly with the Florida Board of Professional Engineers or Board of Architecture before signing a contract, since licensing status can lapse or change.
How often does a Florida condo need a SIRS?
Condo buildings with 3 or more habitable stories need a SIRS at least every 10 years after the condominium's creation, per F.S. 718.112. This ties into the broader milestone inspection schedule, which starts at 25 years (coastal, within 3 miles) or 30 years (inland) after the certificate of occupancy.
What happens if my association doesn't complete a required SIRS?
The association falls out of compliance with F.S. 718.112, which can create legal exposure for the board, complicate insurance renewals, and make mortgage underwriting harder for unit buyers and sellers. Some counties have added their own enforcement timelines on top of the state statute, so check with your county building department.
Can members vote to waive reserve funding after a SIRS is done?
For components covered by a completed SIRS, no. F.S. 718.112 removes the ability to waive or reduce reserve funding for those specific structural items once the study is finished. Non-SIRS reserve items may still be subject to waiver votes depending on your documents and current statutory language, so confirm with association counsel.
Does a reserve study replace the milestone inspection?
No. The milestone inspection (F.S. 553.899) is a separate structural safety pass/fail-style report, while the SIRS is a funding document. They're often done together by the same engineer in one site visit to save cost, but they serve different legal purposes and both may be required.
