TL;DR
A reserve study is a professional estimate of how much money a condo or HOA needs to save for future repairs and replacements of shared property, like roofs, paving, and elevators. Florida requires a structural integrity reserve study (SIRS) for condos 3+ stories, done by a licensed engineer or architect, with the first one due by December 31, 2024 for most buildings under Fla. Stat. § 718.112(2)(g).
What is a reserve study?
A reserve study is a written report, usually done by a specialized firm or a licensed engineer/architect, that looks at the major shared components of a property (roof, paving, painting, plumbing, elevators, structural elements) and estimates two things: how much life each component has left, and how much it will cost to repair or replace it when that time comes. The report then tells the board how much money it should be setting aside each year so the association isn't caught flat-footed when the roof finally gives out. Think of it as a financial forecast paired with a physical inventory. A good study walks the property, photographs and measures the components, pulls local contractor pricing, and builds a 20 to 30 year funding schedule. It is not an inspection for safety defects, although in Florida's condo law the two have become linked. The structural integrity reserve study required under Chapter 718 is a specific, narrower version of a traditional reserve study, focused only on load-bearing and life-safety components, not aesthetic ones like paint or carpet. Most reserve studies fall into two categories: a full study (site visit, physical measurements, component-by-component detail) and an update study (a cheaper refresh of an existing study, usually done every 3 to 5 years without a full site visit). Florida's SIRS statute requires the site-visit version, done by a Florida-licensed engineer or architect, at least every 10 years [1].
What is a reserve study for an HOA?
For a homeowners association, a reserve study works the same way conceptually, but the assets are usually different: roads, retention ponds, clubhouse, pool, gates, irrigation, common landscaping, rather than a shared building structure. The study still estimates remaining useful life and replacement cost for each shared asset and produces a funding plan. HOAs in Florida are governed by Chapter 720, not Chapter 718, and the SIRS mandate that applies to condos does not apply to HOAs. That said, Chapter 720 does require HOAs with reserve accounts to fund them based on a reserve study or a formula unless members vote to waive or reduce funding, and many lenders (Fannie Mae, Freddie Mac) now ask HOA-managed communities for reserve study documentation as part of project approval for mortgages. A reserve study for an HOA is good practice even where it isn't legally mandated, because it's the only real defense against getting hit with a surprise assessment when the road needs repaving. The practical difference: a condo board facing the SIRS deadline has a hard statutory clock and licensing requirement. An HOA board doing a reserve study is mostly protecting itself financially and making special assessments less likely, not checking a box for the state.
What is an HOA assessment (and what is a special assessment)?
An assessment is simply the fee owners pay to fund the association's budget, shared expenses like insurance, landscaping, management, utilities, and reserves. Regular (or 'general') assessments are the recurring monthly or quarterly dues every owner already knows. A special assessment is a one-time, extra charge levied outside the normal budget, usually because there's a gap between what reserves have saved and what a repair actually costs. Special assessments happen for predictable reasons: underfunded reserves, storm damage not fully covered by insurance, a structural repair identified by a milestone inspection or SIRS, or a legal settlement. In post-Surfside Florida, special assessments tied to structural findings have become common and often large, sometimes tens of thousands of dollars per unit in older coastal buildings. A special assessment is legal and enforceable once properly noticed and approved under the association's governing documents and Chapter 718 or 720, and unpaid assessments can result in a lien on the unit. The honest framing for board members: a reserve study exists specifically to make special assessments smaller and less frequent. Every dollar not saved in reserves ahead of time is a dollar that eventually has to come from an emergency special assessment, usually at a worse moment, often after damage has already occurred and repair costs have spiked.
How much should a condo or HOA have in reserves?
There's no single dollar figure that fits every building, because reserve need depends on the age, size, height, and coastal exposure of the property. The honest answer is: enough to fully fund the schedule your reserve study produces, which for most Florida condos built before 2010 means catching up on years of underfunding. Florida law used to let condo associations vote to waive or reduce reserve funding for non-SIRS items. Since the SIRS reforms passed after the Champlain Towers South collapse, associations can no longer waive or use reserve funds for SIRS-related structural components (roof, load-bearing walls, floor, foundation, fireproofing, electrical, plumbing, waterproofing, and structural elements identified in the milestone inspection) once the SIRS is completed [1]. Boards must adopt a budget that includes full funding for those items based on the SIRS, starting with the fiscal year following the study's completion. A rough industry benchmark from reserve study professionals is that a healthy reserve fund is typically 70% funded or better relative to its full theoretical obligation, though many older Florida buildings sit well under 30% funded. There is no statutory percentage target in Chapter 718; the requirement is to fund based on the actual SIRS numbers, not a formula. Boards that want a number to aim for should ask their reserve study preparer for the 'percent funded' figure and treat anything under 50% as a red flag worth discussing with counsel and a structural engineer.
How much does a reserve study cost?
| Full reserve study (small condo, under 50 units) | $2,500 to $6,000 | Site visit, physical inspection, full component list | |
|---|---|---|---|
| Full reserve study (large condo, 100+ units, high-rise) | $8,000 to $20,000+ | More components, more engineering detail | |
| SIRS (structural integrity reserve study, 3+ stories) | $10,000 to $30,000+ | Must be done by licensed FL engineer or architect; scope set by statute | |
| Update study (no site visit) | $500 to $2,000 | Refresh of financial projections only | |
| Update study (with limited site visit) | $1,500 to $4,000 | Partial re-inspection | These ranges are drawn from industry pricing patterns reported by reserve study firms and state guidance; actual quotes depend heavily on unit count, building height, and how many structural systems are being inspected. DBPR does not set or publish a fee schedule for reserve studies or SIRS reports; pricing is set by the market and by the engineering firm's own scope [2]. Boards should get at least two or three quotes and confirm the preparer is properly licensed (a Florida-licensed engineer or architect for SIRS work specifically) before signing a contract [1]. |
Reserve study costs vary by property size, number of components, and whether it's a full study or update. For a typical Florida condo, expect a range roughly like this: | Study type | Typical cost range | Notes |
What does Florida law actually require for reserve studies and SIRS?
Florida Statute § 718.112(2)(g) requires condo associations with buildings three stories or more in height to have a structural integrity reserve study completed at least once every 10 years, performed by a licensed engineer or architect, covering specific structural components: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing and fire protection systems, electrical systems, plumbing, waterproofing and exterior painting, and windows [1]. The statute states the SIRS 'must include' a study of the useful life and replacement cost or deferred maintenance expense of each required component, based on either a visual inspection or, if the inspector requires more, further inspection [1]. Associations that already completed a milestone inspection can often use that engineer's findings to inform the SIRS, but they are two separate deliverables under two different statutory provisions (§ 553.899 for milestone inspections, § 718.112 for SIRS). Once a SIRS is completed, the association's board must incorporate its findings into the reserve budget starting the next fiscal year, and members can no longer vote to waive, reduce, or use reserves earmarked for SIRS components for anything other than their designated purpose, per § 718.112(2)(f) [1]. This is a real change from pre-2022 law, when boards routinely voted to keep reserves low. Confirm current deadlines and any legislative amendments with your association's counsel, since the legislature has revisited these dates and thresholds more than once since 2022 [3].
Are HOA or condo special assessments tax deductible?
Generally, no. Special assessments paid to a condo or HOA for capital improvements or major repairs are not deductible on your personal federal income tax return if the unit is your primary residence, in the same way regular HOA dues aren't deductible for a personal residence. The IRS treats these payments as personal living expenses, not as deductible taxes or casualty losses [4]. There are narrow exceptions. If you own the unit as a rental property, special assessments for repairs may be deductible as a business expense, and assessments for capital improvements may need to be added to your cost basis and depreciated rather than deducted immediately, per IRS Publication 527 guidance on rental property expenses [5]. If part of your home is a qualified home office, a portion of the assessment might be deductible on that basis. In all cases, this is a question for a CPA or tax attorney familiar with your specific ownership situation, not something a board or property manager can advise on.
How does a reserve study actually get done, step by step?
A licensed provider (engineer, architect, or reserve specialist firm, depending on whether it's a SIRS or a traditional study) visits the property and physically inspects the components in scope. For SIRS work, Florida law requires this be a licensed engineer or architect [1]. They inventory each component, note its age, condition, and estimated remaining useful life. They then research current replacement or repair costs, often using regional contractor pricing and cost-estimating databases. The final report gives the board, for each component: current age, useful life, remaining useful life, and estimated replacement cost, plus a recommended funding schedule (how much to contribute per year, per component, and in total) so the association isn't relying on any single large withdrawal or emergency assessment. The board should review the draft with the preparer before it's finalized, ask clarifying questions about assumptions (inflation rate used, interest rate on reserve accounts, cost estimates), and then present the completed SIRS to owners as required. Boards juggling this alongside a milestone inspection and annual budget meetings often find the scheduling and owner communication harder than the engineering itself; that's the gap a tool like the $199 Board Compliance Kit is built to close, since it organizes deadlines, document requests, and owner notices around your building's actual SIRS and milestone dates. It does not replace the licensed engineer or architect who must perform the study itself.
What happens if a board skips or delays the reserve study?
Skipping a required SIRS past its deadline exposes the association to real risk: potential DBPR enforcement action, an inability to legally waive reserve funding for structural items, and, more practically, a much higher chance of a large emergency special assessment when a structural problem is finally discovered without warning. Florida's Condominium Act gives DBPR's Division of Florida Condominiums, Timeshares, and Mobile Homes authority to investigate complaints and take enforcement action against associations that violate Chapter 718 requirements [2]. Beyond legal exposure, there's a market cost. Lenders and title companies increasingly ask for SIRS and milestone inspection status before approving mortgages in condo buildings, following Fannie Mae and Freddie Mac's tightened condo project review standards after Surfside. A building with no SIRS on file, or a lapsed one, can become harder for owners to sell or refinance in, which hits resale values association-wide, more than for the board. Boards that are behind should not panic-buy the cheapest available study. Get a licensed engineer or architect, confirm their Florida license status through the Department of Business and Professional Regulation's license search, and build in enough lead time (often 60 to 120 days depending on building size and inspector availability) since demand for SIRS providers has been high statewide since the 2024 deadline wave [2].
How do reserve studies, milestone inspections, and SIRS deadlines fit together?
These are three separate but related requirements, and boards often conflate them. The milestone inspection (Fla. Stat. § 553.899) is a structural safety inspection of the building itself, first due when a building turns 30 years old (25 years if within three miles of the coast), then every 10 years after. It's performed by a licensed engineer or architect and produces a phase one, and if needed phase two, report on structural safety. The SIRS is a financial planning document that estimates remaining life and replacement cost for structural components, informed by (but distinct from) the milestone inspection findings. It's required for condos 3+ stories and must be done at least every 10 years. A traditional (non-SIRS) reserve study is broader still, covering non-structural components like paint, carpet, and amenities, and isn't mandated by Chapter 718 the way SIRS is, though many associations do them anyway for full financial planning. If your building is approaching any of these thresholds, cross-check the milestone inspection rules against your building's certificate of occupancy date and distance from the coastline.

Frequently asked questions
What is a reserve study?
A reserve study is a professional report that inventories a property's shared components (roof, paving, elevators, structural elements), estimates each one's remaining useful life, and projects the cost to repair or replace it. The report produces a funding schedule so the board knows how much to save each year instead of relying on emergency special assessments.
What is a reserve study for an HOA?
For an HOA, a reserve study covers shared community assets like roads, ponds, clubhouses, and pools rather than a building structure. Chapter 720 doesn't mandate a SIRS the way Chapter 718 does for condos, but HOAs with reserve accounts must fund them based on a study or formula unless members vote to waive or reduce that funding.
What is an HOA assessment?
An HOA assessment is the fee owners pay to fund the association's operating budget and reserves. Regular assessments are the recurring dues every owner pays; a special assessment is an extra, one-time charge levied outside the normal budget, usually to cover a funding gap for a major repair or unexpected damage.
How much should a condo or HOA have in reserves?
There's no single statutory percentage in Florida law; the requirement is to fund reserves based on the actual figures in your reserve study or SIRS, not a formula. Industry benchmarks often cite 70% funded as healthy, while many older Florida buildings sit well under 30% funded relative to their full theoretical obligation.
How much does a reserve study cost?
A full reserve study typically runs $2,500 to $6,000 for a small condo and $8,000 to $20,000 or more for a large high-rise. A SIRS, which must be done by a licensed Florida engineer or architect, often costs $10,000 to $30,000 or more depending on building size and complexity. Update studies without a site visit cost far less, often $500 to $2,000.
Are HOA or condo special assessments tax deductible?
Generally no, for a primary residence. The IRS treats special assessments as personal living expenses, similar to regular HOA dues. Exceptions exist for rental property owners, where repair-related assessments may be deductible as business expenses and capital improvement assessments may be added to cost basis and depreciated. Consult a CPA for your specific situation.
Who is required to perform a Florida SIRS?
Florida law requires the structural integrity reserve study to be performed by a Florida-licensed engineer or architect. Boards should verify the preparer's license through the Department of Business and Professional Regulation before signing a contract, since an unlicensed or improperly licensed report will not satisfy the statutory requirement.
What components must a SIRS cover under Florida law?
Fla. Stat. § 718.112(2)(g) lists roof, load-bearing walls, primary structural members and systems, floor, foundation, fireproofing and fire protection systems, electrical systems, plumbing, waterproofing and exterior painting, and windows. Each must be evaluated for remaining useful life and estimated replacement or deferred maintenance cost.
Can an association waive SIRS reserve funding by member vote?
No, not once the SIRS is completed. Under the post-2022 reforms to § 718.112(2)(f), associations can no longer vote to waive, reduce, or divert reserve funding for the structural components identified in a completed SIRS. This is a major change from prior law, which allowed broader reserve waivers.
How is a SIRS different from a milestone inspection?
A milestone inspection under § 553.899 is a structural safety check of the building, first due at 30 years (25 years near the coast) and every 10 years after. A SIRS is a financial planning document estimating replacement costs and useful life for structural components, informed by but separate from the milestone inspection's safety findings.
What happens if a board doesn't complete its required SIRS?
The association risks DBPR enforcement action, loses the ability to legally waive reserve funding for structural items, and faces higher odds of a large surprise special assessment if a structural problem surfaces later. Lenders following Fannie Mae and Freddie Mac condo review standards may also flag the building, making units harder to finance or sell.
Does a reserve study replace the milestone inspection or vice versa?
No. They're separate statutory requirements with separate purposes: milestone inspections assess structural safety, and a SIRS or reserve study assesses funding needs for future repairs. Many boards schedule them close together since the same engineer or architect can often use overlapping site data, but each produces its own required report.
