TL;DR
A reserve study is an engineer or reserve specialist's assessment of a building's common elements, their remaining life, and the money needed to replace them. Florida condos with buildings 3+ stories must have one done under Fla. Stat. 718.112 as part of SIRS. Costs typically run $3,000 to $15,000+ depending on building size and complexity.
What is a reserve study?
A reserve study is a physical inspection and financial analysis of an association's common elements, done to figure out how much money the association needs to save now so it can pay for roof replacements, repaving, elevator overhauls, and similar big-ticket items later without a surprise bill to owners. A typical reserve study has two parts. The physical analysis inventories the major common elements (roof, paint, pavement, pool, elevators, structural components) and estimates each one's remaining useful life. The financial analysis takes that inventory and calculates how much the association should be putting into reserves each year, comparing a straight-line "component" method against a simpler "pooled" method that blends multiple components into one fund. In Florida, the analysis has gotten more specific since 2022. For condo buildings 3 stories or higher, the milestone inspection and Structural Integrity Reserve Study (SIRS) process folded a defined set of structural items into the reserve requirement: roof, load-bearing walls, floor, foundation, fireproofing, fire protection systems, plumbing, electrical, waterproofing, and windows/exterior doors, among others listed under Fla. Stat. 718.112(2)(g) [1]. Those items can no longer be waived or reduced by a vote of the membership, which was possible for ordinary reserve line items before the law changed. A reserve study is not an inspection report and it is not a legal opinion on your governing documents. It is a numbers-and-engineering document that tells the board what to save and when to expect to spend it. Boards still need their own attorney to interpret how the results interact with the association's declaration and bylaws; confirm any document-specific questions with counsel.
What is a reserve study for an HOA?
For a homeowners association (as opposed to a condominium), a reserve study works the same way conceptually: an inventory of common-area assets (roads, clubhouse, pool, gates, drainage) with a funding plan attached. The mechanics differ because most of Florida's SIRS and milestone inspection statutes apply specifically to condominiums and cooperatives, not single-family HOAs [1]. Florida Statute chapter 720 governs homeowners associations, and its reserve provisions are looser than the condo statute. Under Fla. Stat. 720.303(6), HOAs are generally required to fund reserves for items the association is obligated to maintain only if reserves were established as part of the initial budget or later approved by a vote of the membership; there isn't a parallel SIRS structural mandate for HOAs the way there is for 3+ story condo buildings [2]. That gap matters for board members moving between property types. If you sit on an HOA board with condo-style buildings (say, a townhome community with 3-story structures), don't assume the milestone/SIRS rules apply automatically. Check with your association's counsel about which chapter, 718 or 720, actually governs your community and what that means for reserve obligations. See our related breakdown on reserve study for condo association requirements and how they compare to the more flexible HOA framework covered in our HOA reserve study guide.
What is an HOA assessment (and what is an HOA special assessment)?
An HOA assessment is a fee the association charges owners to fund operations and reserves, usually billed monthly or quarterly as part of regular dues. A special assessment is a separate, one-time charge levied when the regular budget and reserves don't cover an unexpected cost, a shortfall, or a major project like a roof replacement or storm repair. Condo associations in Florida can levy special assessments under authority in their declaration and Fla. Stat. 718.116, which addresses assessments generally, including the association's lien rights when an owner doesn't pay [3]. The board typically needs to follow notice requirements in the bylaws (a meeting notice describing the purpose and estimated amount) before voting to approve one. Special assessments have become far more common since the 2021 Champlain Towers South collapse in Surfside, which prompted the legislature to eliminate the option to waive structural reserves. Buildings that had been underfunding reserves for years suddenly needed to catch up, and many boards had no choice but to assess owners directly rather than phase the cost in gradually. For a deeper look at how these assessments get structured, what triggers them, and how owners can push back procedurally (not on the substance of a properly noticed vote), see our guide on HOA special assessment rules.
How much should an HOA have in reserves?
There's no single dollar figure that applies to every association, because the right reserve balance depends entirely on the age, size, and condition of the specific building's components. The honest answer is: enough to cover the fully funded reserve number your reserve study calculates, not an arbitrary percentage or round number. A reserve study typically expresses funding adequacy as a percentage of "fully funded" status, meaning the reserve balance relative to the ideal balance given each component's age and remaining life. Associations under 30% funded are generally considered at meaningful risk of needing a special assessment; those over 70% are usually considered well-positioned, though there's no statutory bright line in Florida for this percentage. National reserve study associations, like Community Associations Institute-affiliated reserve specialists, commonly use 70% as a rule-of-thumb health threshold, but that's an industry convention, not a legal requirement. What Florida law does require, for condos 3+ stories, is that structural reserve line items identified in the SIRS can't be underfunded by board or membership vote starting with reserve budgets adopted on or after December 31, 2024, per the amendments to Fla. Stat. 718.112(2)(f)-(g) [1]. That's a floor, not a target: it means the structural components must be funded at the level the reserve study calculates, full stop, regardless of what owners vote for. Boards sometimes ask for a flat number like "three months of operating expenses" as a reserve target, borrowed from municipal or nonprofit finance. That standard doesn't map well onto condo reserves, where the liability is a 30-year roof replacement schedule, not monthly cash flow. Ignore that shortcut and use the study's actual component-by-component numbers instead.
How much does a reserve study cost?
| Full/initial reserve study | $3,000-$15,000+ | Once, then updated | |
|---|---|---|---|
| Update with site visit | $1,500-$5,000 | Every 3-5 years | |
| Desktop update (no site visit) | $500-$2,000 | Annually between full studies | |
| Milestone inspection (structural, separate requirement) | Varies by building size and engineer, often $5,000-$25,000+ | Every 10 years after initial (at 25 or 30 years) | Costs above are general industry ranges, not fixed statutory fees; get multiple quotes and confirm current pricing with providers in your county. |
Reserve study costs in Florida generally range from about $3,000 for a small condo association to $15,000 or more for a large, complex high-rise, according to cost ranges reported by state-licensed reserve specialists and engineering firms that perform this work. The main cost drivers are building size, number of common-element components, and whether the study requires a full site visit with a licensed engineer versus a desktop update. A first-time, full reserve study (sometimes called a Level 1 or full study) costs more than an update study (Level 2 or 3), because the initial study requires a complete physical inventory and condition assessment of every component. Update studies, done every few years, generally cost less because they're adjusting numbers rather than starting from scratch. For the SIRS specifically, Florida requires the structural inspection portion to be performed by a licensed engineer or architect, per Fla. Stat. 718.112(2)(g), and DBPR maintains a license search tool covering engineers and architects through its Division of Professions [1]. That licensing requirement is separate from, and in addition to, whatever firm your association hires for the financial/reserve-funding calculation, though many firms offer both services together. Budget-wise, boards should plan for the reserve study cost itself to be a small operating-budget line item, not something funded out of reserves. Treat it as a recurring cost of doing business, the same way you'd budget for the annual audit or management company fee. | Study type | Typical cost range | Frequency |
Who is qualified to perform a reserve study in Florida?
For the financial/component side of a reserve study, Florida doesn't require a specific state license the way it does for engineers. Many firms doing this work employ Reserve Specialists (RS) or Professional Reserve Analysts (PRA), credentials issued by national industry organizations rather than the state of Florida. For the structural inspection portion required under SIRS, the statute is explicit: the inspection must be performed by a licensed engineer or architect. Fla. Stat. 718.112(2)(g) requires that the study include a visual inspection and be performed by "a licensed engineer or architect" for the structural components listed in the statute [1]. DBPR's license search tool lets boards verify an individual engineer's or architect's active license status directly. Boards should ask any prospective provider for their license number (if it's the structural portion), references from other Florida condo associations, and a sample report so the board can see the format and level of detail before signing a contract. A vague, boilerplate report that doesn't break out each of the statutorily required structural components isn't going to satisfy the SIRS requirement, and the board will end up paying twice. Don't confuse a reserve study provider with a milestone inspection provider automatically, though some firms do both. The milestone inspection (the structural safety inspection at 25 or 30 years, addressed separately under Fla. Stat. 553.899) and the SIRS reserve study are related but distinct deliverables, often produced by the same engineering firm but sometimes not [4].
How do reserve studies interact with milestone inspections and SIRS?
The milestone inspection and the SIRS are two different reports triggered by two different statutes, but they usually get commissioned together because they cover overlapping structural components. The milestone inspection under Fla. Stat. 553.899 is a one-time structural safety check required at 30 years for most buildings (25 years if within 3 miles of the coast), then every 10 years after [4]. The SIRS, under Fla. Stat. 718.112(2)(g), is the ongoing reserve funding study that must be updated at least every 10 years and must specifically address the structural components identified in the statute [1]. Practically, if your milestone inspection engineer flags a deficiency, that finding usually feeds directly into the reserve study's estimate of remaining useful life and replacement cost for that component. Boards juggling both deadlines at once, especially older buildings near the coast facing the 25-year trigger, often find it easier to hire one firm for both reports so the underlying condition assessment doesn't have to be duplicated. That can also reduce the total cost, since the engineer isn't making two separate site visits. For the full milestone inspection timeline and how the 25 vs. 30-year thresholds get calculated by coastal distance, see our dedicated milestone inspection coverage on this site. And for the reserve-specific mechanics of what the statute requires component by component, our reserve study explainer walks through the statute in more detail.
Are HOA special assessments tax deductible?
Generally, no. Special assessments paid to a homeowners association or condo association are not tax deductible for individual owners, because the IRS treats them as capital improvements to your property rather than as deductible expenses, similar to how regular HOA dues aren't deductible for a primary residence. There are narrow exceptions. If the assessment funds a capital improvement (a new roof, structural repair) and you later sell the unit, you may be able to add the assessment amount to your cost basis, which reduces your taxable gain at sale. IRS Publication 523 explains that "settlement fees and closing costs" along with amounts spent on capital improvements can adjust your home's basis, which is the relevant framework for a basis adjustment tied to a special assessment [5]. That's a basis adjustment, not a current-year deduction, and the rules depend on your specific facts. If the unit is a rental property rather than your primary residence, some portion of the assessment might be deductible as a business expense or depreciated over time, but that's a real estate and tax question specific to your situation, not a blanket rule. Owners should talk to a CPA or tax preparer about their specific facts; this isn't tax advice and the answer changes based on how the assessment is used and whether the property is a rental. The IRS doesn't publish a condo-specific special assessment deduction rule; guidance on capital improvements versus repairs generally comes from IRS Publication 523 (Selling Your Home) and related basis rules, which owners' tax preparers should reference directly for current-year details [5].
What should a board look for when hiring a reserve study provider?
Ask for three things before signing any contract: a sample report from a similar-sized Florida condo, proof of the engineer's or architect's active license (if the SIRS structural portion is included), and a clear breakdown of what's covered in the fee versus billed as an extra. A good sample report shows every common-element component itemized separately, not lumped into vague categories like "building envelope." It should show remaining useful life estimates, replacement cost estimates in current dollars, and a funding plan comparing at least two methods (straight-line component vs. pooled). Ask how the firm handles updates. Since the SIRS must be updated at least every 10 years under Fla. Stat. 718.112(2)(g), and many boards prefer more frequent check-ins (every 3-5 years) to stay ahead of cost inflation on materials like roofing and concrete, find out upfront whether update pricing is locked in or negotiated fresh each time [1]. Finally, ask about timeline. A rushed reserve study, especially one done under deadline pressure right before a milestone inspection due date, tends to produce weaker analysis. Building in 60-90 days of lead time before your statutory deadline gives the engineer room to do a proper site visit and gives the board room to review the draft before it becomes official. Organizing the paperwork side, tracking which deadline applies to your building, and keeping owners informed along the way is a separate job from the engineering work itself. That's the gap a $199 Building-Specific Board Compliance Kit is built to fill: it doesn't replace your engineer or reserve specialist, but it helps the board schedule the right inspections in the right order, organize the resulting reports, and communicate deadlines to owners without missing a statutory date.
What happens if an association skips or delays a reserve study?
Skipping a required SIRS puts the association out of compliance with Fla. Stat. 718.112(2)(g), which can expose board members to liability questions and complicate the association's ability to sell units or secure financing, since lenders and title companies increasingly ask for SIRS and milestone documentation before closing. Florida's Division of Florida Condominiums, Timeshares, and Mobile Homes, part of DBPR, has enforcement authority over condo associations under Fla. Stat. 718.501, which grants the division the power to investigate complaints and enforce chapter 718 [6]. Owners or other board members can file complaints with DBPR if they believe the association isn't meeting its statutory obligations. Beyond the regulatory risk, delay has a straightforward financial cost: the longer a building waits to fund its structural reserves properly, the bigger the eventual special assessment tends to be, because deferred maintenance compounds and materials costs generally rise faster than a delayed reserve contribution schedule can catch up to. Boards that inherited years of underfunded reserves from a prior board aren't personally liable for that history, but they are responsible for fixing it going forward. That usually means a combination of a reserve study to establish the real number, a phased funding plan, and, in many buildings, an unavoidable special assessment to close the gap in a reasonable timeframe.
How does Florida's condo reserve law affect what a study must include?
Since the 2022 and 2023 amendments to Fla. Stat. 718.112, reserve studies for condos 3+ stories must specifically address the structural components enumerated in the statute, and boards and owners can no longer vote to waive or reduce reserve funding for those specific items [1]. This changed the reserve study from a purely financial planning tool into a document with direct legal consequences for what the association must fund. The statute lists roof, load-bearing walls or other primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, and windows and exterior doors as required components, among others specified in the text [1]. If your reserve study provider's report doesn't clearly separate these out with individual funding lines, it likely doesn't meet the statutory bar, and the association should push back before accepting the final report. The practical effect for boards: reserve contributions for these specific line items are now effectively mandatory once the SIRS is complete, starting with reserve budgets adopted on or after December 31, 2024. There's ongoing legislative activity around reserve relief and timeline adjustments, so confirm the current version of the statute and any transition provisions with your association's counsel before finalizing next year's budget. For a plain-language walkthrough of what changed and when, our Florida condo reserve fund relief coverage tracks the legislative timeline and any relief provisions passed since the original 2022 reforms.
Frequently asked questions
What is a reserve study?
A reserve study is a physical inspection and financial analysis of an association's common elements (roofs, elevators, pavement, and for Florida condos 3+ stories, specific structural components) that calculates how much money the association needs to save each year to pay for future repairs and replacements without a surprise special assessment.
What is a reserve study for an HOA?
For a homeowners association, a reserve study inventories common-area assets like roads, clubhouses, and pools, and builds a funding plan for their eventual repair or replacement. Unlike Florida condos 3+ stories, most HOAs aren't subject to the SIRS structural mandate under Fla. Stat. 718.112, so requirements vary by governing documents.
What is an HOA assessment?
An HOA assessment is the regular fee (dues) an association charges owners to fund operating costs and reserves, typically billed monthly or quarterly. It's distinct from a special assessment, which is a one-time charge for an unexpected cost or major project not covered by the regular budget.
How much should an HOA have in reserves?
There's no single dollar figure; the right amount is whatever the association's reserve study calculates as the fully funded level for each component given its age and remaining life. Industry convention often uses 70% funded as a health benchmark, but Florida law only sets a hard floor for specific structural items in condos 3+ stories under Fla. Stat. 718.112.
How much does a reserve study cost?
Reserve studies in Florida typically cost $3,000 to $15,000 or more for an initial full study, depending on building size and complexity. Update studies every 3-5 years generally cost less, from around $500 for a desktop update to $5,000 for one with a full site visit.
Are HOA special assessments tax deductible?
Generally no. Special assessments are usually treated as capital improvements, not deductible expenses, similar to regular HOA dues on a primary residence. In some cases the assessment amount can be added to your cost basis to reduce taxable gain when you sell, or partially deducted if the unit is a rental. Talk to a CPA about your specific situation.
What is a SIRS and how is it different from a reserve study?
A Structural Integrity Reserve Study (SIRS) is a specific type of reserve study required under Fla. Stat. 718.112 for condo buildings 3+ stories. It covers the same funding-plan concept as a general reserve study but must address a defined list of structural components and can't have those items waived by owner vote.
Who can legally perform a reserve study in Florida?
The financial/component analysis is often done by firms employing nationally credentialed Reserve Specialists, though Florida doesn't license this specific role. The structural inspection portion required for SIRS must be performed by a licensed engineer or architect under Fla. Stat. 718.112(2)(g); verify licenses through DBPR's license search tool.
How often does a reserve study need to be updated?
Under Florida's SIRS requirement, the structural reserve study must be updated at least every 10 years, per Fla. Stat. 718.112(2)(g). Many reserve specialists recommend a lighter update every 3-5 years between full studies to keep pace with construction cost inflation.
Does every Florida condo need a SIRS?
Condo buildings 3 stories or higher generally need a SIRS under Fla. Stat. 718.112, with the requirement applying to buildings that reached their milestone inspection threshold. Smaller buildings and certain exemptions may apply; confirm your building's specific obligation with your association's counsel and local building department.
What happens if a Florida condo association doesn't do a required reserve study?
The association is out of compliance with Fla. Stat. 718.112, which can trigger DBPR complaints under the division's enforcement authority in Fla. Stat. 718.501, complicate unit sales and mortgage approvals, and leave the board exposed on funding decisions. Delaying also tends to increase the eventual cost, since deferred maintenance and rising material costs compound over time.
Can an HOA or condo waive reserve funding requirements?
For the structural components listed in Florida's SIRS statute (roof, load-bearing walls, foundation, and others under Fla. Stat. 718.112(2)(g)), owners and boards can no longer vote to waive or reduce funding as of the amendments effective for reserve budgets adopted on or after December 31, 2024. Non-structural reserve items may still have different rules; confirm with counsel.
