Condominium reserve study: what florida boards must know

Last updated 2026-07-24

what is a reserve study?

A reserve study is a professional inspection and financial forecast of a building's major shared components, the roof, elevators, structure, pool, paving, plumbing risers, and so on. The person doing the study looks at what condition each component is in, estimates how many years it has left, figures out what it will cost to repair or replace, and then builds a funding schedule so the association isn't caught flat-footed when the bill comes due. Think of it as the building's own retirement plan. You wouldn't want to discover the day your roof fails that nobody set aside money for a new one. A good reserve study tells the board: here's what's coming, here's roughly when, and here's what it costs in current dollars and inflated dollars. Most reserve studies have two parts. The physical analysis (site visits, component inventory, remaining useful life estimates) and the financial analysis (current reserve fund balance, contribution levels, and a multi-year funding plan, usually 20 or 30 years out). Some studies are full studies with an on-site inspection; others are updates that lean on the prior study plus a phone call or a walk-through. Florida's Structural Integrity Reserve Study (SIRS), created after the 2021 Surfside collapse, is a specific, statutorily-defined version of this for condo and cooperative buildings three stories and taller ^[1].

what is a reserve study for an hoa?

For a homeowners association, a reserve study works the same way conceptually, it inventories the common elements the HOA is responsible for (roads, clubhouse, pool, gates, retention ponds, signage) and projects when each will need major repair or replacement. The difference is legal, not mechanical: most single-family HOAs in Florida are not currently subject to the mandatory SIRS and 100% funding rules that apply to condominiums under Chapter 718. Those rules target condo and cooperative buildings, not HOAs governed by Chapter 720 ^[2]. That doesn't mean HOA boards should skip it. A voluntary reserve study is still the best tool an HOA has for avoiding a surprise special assessment. If your HOA has a shared roof structure (townhomes, for instance), an elevator, or a parking garage, the risk profile starts looking a lot like a condo's, even if the statute doesn't require the same paperwork. For more on how the state-mandated version differs from a voluntary study, see our guide on hoa reserve study requirements and how boards can run one even when it isn't legally required.

what is an hoa assessment (and what is a special assessment)?

An HOA assessment is the regular fee owners pay for the association's operating budget and reserve contributions, usually monthly or quarterly. It covers landscaping, insurance, management, utilities for common areas, and (ideally) reserve funding for future big-ticket repairs. A special assessment is different. It's a one-time (or short-term) extra charge the board levies when there isn't enough in reserves, or in the operating budget, to cover an unexpected or underfunded cost, storm damage, a failed lift station, a milestone inspection repair bill. Special assessments are legal under both Chapter 718 (condos) and Chapter 720 (HOAs) in Florida, but boards generally need to follow notice and voting procedures spelled out in the statute and the association's own governing documents ^[3]. The connection to reserve studies is direct: the better funded your reserves are, the less likely you'll need a special assessment when something breaks. Underfunded reserves are, by a wide margin, the number one reason Florida condo boards end up hitting owners with five-figure special assessments after a milestone inspection or SIRS reveals deferred structural work. If your board is staring down one now, our piece on the hoa special assessment process walks through notice requirements and payment plan options.

how much should an hoa (or condo) have in reserves?

There's no single dollar figure that's right for every building, it depends on square footage, age, number of components, and local repair costs. But there are two accepted benchmarks reserve professionals use to judge whether a fund is healthy. The first is percent funded: your current reserve balance divided by what the fund should ideally hold given the remaining life and cost of every component. Reserve specialists generally consider 70% funded or higher to be strong, 30% to 70% is fair, and below 30% is considered weak or 'at risk' territory where special assessments become likely ^[4]. Many associations nationally sit in the 30% to 40% range, according to reserve study industry surveys, which is part of why special assessments are so common. The second is the full-funding standard now required by Florida law for SIRS components. Fla. Stat. § 718.112(2)(f) requires condo associations to fund reserves for SIRS-covered items (structural components, not cosmetic ones) based on 100% of the study's findings, with no ability to waive or reduce that funding by member vote once the SIRS is complete ^[1]. That's a meaningful change from the old rule, which let owners vote every year to waive or underfund reserves entirely. As a rule of thumb for budgeting conversations: if your reserve study shows you're under 50% funded and your building has an aging roof or facade past 25 years old, expect that gap to show up as either a large multi-year contribution increase or a special assessment. There isn't a way around the math; the money has to come from somewhere.

how much does a reserve study cost?

Costs vary a lot based on building size, number of components, and whether it's a full study or an update. As a general range, expect roughly $3,000 to $8,000 for a smaller condo (under 50 units) doing a full study, and $8,000 to $20,000+ for larger or more complex buildings with elevators, parking structures, or multiple pools ^[5]. Florida's SIRS specifically, because it requires inspection by a licensed engineer or architect and covers a defined list of structural components (roof, load-bearing walls, floor, foundation, fireproofing, electrical, plumbing, waterproofing, exterior painting, windows, and more per § 718.112), tends to run toward the higher end of that range for buildings over 100,000 square feet or with structural complexity ^[1]. Update studies (no full on-site inspection, just revised numbers) usually cost a fraction of a full study, sometimes under $1,000 to $2,000, but Florida's SIRS statute has specific requirements about who can perform the study (a licensed engineer or architect, per § 718.112(2)(g)) and how often it must be redone, so check with your engineer and association counsel before assuming an update will satisfy the statute ^[1]. Boards sometimes balk at the sticker price and try to skip the study or use an unlicensed contractor's estimate instead. That's a mistake for condo buildings covered by the SIRS mandate, the statute is specific about who is qualified to perform it, and an unqualified study likely won't satisfy the requirement, leaving the board exposed if regulators or owners later challenge it. For a fuller cost breakdown by building size and age, see our guide on reserve study for condo association budgeting.

what is the difference between a milestone inspection and a SIRS?

These get confused constantly, so it's worth being direct: a milestone inspection is a structural safety inspection; a SIRS is a financial and component-condition study tied to reserve funding. They're related but they're not the same document, and Florida law requires both, on different timelines, for qualifying condo buildings. The milestone inspection, required under Fla. Stat. § 553.899, is a structural integrity check by a licensed engineer or architect, generally due at 30 years after the certificate of occupancy (25 years if within three miles of the coast), and every 10 years after that ^[6]. It answers the question: is this building structurally sound right now? The SIRS, required under § 718.112, is the reserve funding study covering the components listed above. Associations with buildings three stories or higher must complete their first SIRS and turn results over to unit owners; the milestone inspection findings often feed directly into the SIRS because a structural problem found in the milestone inspection changes the remaining useful life estimate for that component in the reserve study ^[1][6]. See our full breakdown in the milestone-inspections hub if your building is approaching its 25 or 30 year mark and you're not sure which document comes first.

are hoa special assessments tax deductible?

Generally, no. For a personal residence, special assessments (and regular HOA dues) are considered a personal living expense by the IRS, not a deductible one, similar to how you can't deduct your homeowner's insurance premium or routine home maintenance ^[7]. That's true whether the special assessment is for a new roof, storm damage repair, or a SIRS-related structural fix. There are narrow exceptions. If the unit is a rental property, special assessments for repairs may be deductible as a rental expense, and assessments for capital improvements may be added to your cost basis in the property (which reduces capital gains tax when you sell) rather than deducted immediately . If the assessment relates to a federally declared disaster and specific casualty loss rules apply, there may be a separate path, but that's a narrow, fact-specific area. This isn't tax advice, and every owner's situation differs based on filing status, whether the unit is a primary residence, rental, or second home, and how the assessment is characterized by the association. Talk to a CPA before assuming either way. The IRS's own guidance on rental property expenses versus capital improvements is a good starting point for owners trying to sort this out .

what triggers a mandatory reserve study in florida?

Building height and age are the two triggers that matter most. Under Fla. Stat. § 718.112, condominium associations with buildings three stories or higher must complete a SIRS, and the reserve funding rules tied to that study (no waiving, 100% funding of SIRS components) apply once the study is complete ^[1]. The statute's SIRS deadline, after legislative extensions in 2023 and 2024, is December 31, 2024 for associations to complete their initial study, with the funding requirements kicking in for the fiscal year budget adopted after the study is turned over to the association ^[1][5]. Boards should confirm the current deadline with counsel, because the legislature has amended this timeline more than once since Surfside and may do so again. Age matters for the separate milestone inspection trigger: 30 years from the certificate of occupancy for most buildings, 25 years if the building sits within three miles of a coastline, as determined by the local authority having jurisdiction ^[6]. Local governments can also set earlier trigger points; check with your county building department because some counties (Miami-Dade and Broward, notably) had older local milestone inspection ordinances before the statewide law existed ^[6]. Cooperatives with residential buildings of similar height and age face parallel requirements, and DBPR's Division of Florida Condominiums, Timeshares, and Mobile Homes is the state agency that regulates and provides guidance for community associations working through these rules .

who can perform a reserve study or SIRS in florida?

Florida law is specific here, and boards get this wrong more often than you'd think. For the statutory SIRS, § 718.112(2)(g) requires the study be performed by a person qualified to conduct such a study, which the statute and DBPR guidance interpret as a licensed engineer or architect ^[1]. A community association manager, a general contractor, or a reserve-planning consultant without the right license can help organize and administer the process, but can't sign off on the SIRS itself. For non-SIRS reserve studies (voluntary studies, HOA studies, or studies for buildings under three stories not covered by the mandate), there's more flexibility. Many boards hire members of the Community Associations Institute's Reserve Specialist (RS) credential program or firms that specialize in reserve studies without an engineering license attached, since the study doesn't require structural certification the way a SIRS does. One thing a board should never do: let an unlicensed vendor's cost estimate substitute for the actual required study. If your building needs a SIRS, get a licensed engineer or architect on it, full stop. Getting this wrong doesn't just waste money, it can leave the association's funding decisions exposed to challenge later.

what happens if a board doesn't complete its reserve study or SIRS on time?

The consequences run in two directions: legal exposure and financial exposure, and the second one usually hurts more. Legally, associations that miss the SIRS deadline are out of compliance with Fla. Stat. § 718.112, which can expose the board to legal claims and complicate the association's ability to enforce reserve waivers or funding decisions made in the interim ^[1]. Practically, DBPR has enforcement authority over condo associations and can investigate complaints related to statutory non-compliance . Financially, the bigger risk is what happens when a component fails before the board has a funding plan for it. Delaying the study doesn't delay the roof leak or the concrete spalling, it just delays the board's awareness of it, which usually means the repair becomes an emergency special assessment instead of a planned, budgeted expense spread over several years. That's the exact pattern that led to the legislative response after Surfside; deferred maintenance combined with underfunded reserves is what turns a fixable problem into a catastrophic one. Boards that are behind should get moving now rather than waiting for a perfect quarter. A late SIRS is better than no SIRS, and starting the financial planning conversation with owners early, even with incomplete numbers, beats springing a six-figure assessment on them with no warning.

how do florida condo reserve rules compare to other states?

Florida's post-Surfside reserve and inspection framework is more prescriptive than most states'. California, for comparison, requires HOAs to conduct a reserve study every three years and disclose funding percentages to owners annually, but doesn't mandate 100% funding the way Florida now does for SIRS components . Many states have no statutory reserve study requirement at all, leaving it entirely to the association's governing documents and board discretion. What makes Florida distinct is the combination: a mandatory structural inspection (milestone) tied to a specific age and coastal-proximity trigger, paired with a mandatory, licensed-professional reserve study (SIRS) that removes the board's ability to waive funding for structural components. That one-two combination doesn't exist in most other states yet, though several (including some legislative proposals in states like Illinois and Virginia after Surfside) have looked at similar frameworks. If you're comparing notes with a board in another state, or you manage properties in more than one, our other-states hub tracks how these requirements differ so you're not assuming Florida's rules apply somewhere they don't. For Florida boards specifically working through the SIRS process and worried about the funding cliff, our explainer on florida condo reserve fund relief covers what legislative relief options (like phased funding or lender programs) have actually passed versus what's still a proposal.

how do boards actually organize and act on a reserve study once it's done?

Getting the study done is only step one. The harder part, and the part most boards struggle with, is turning a 40-page engineering and financial report into an actual budget line, a member communication plan, and a documented compliance record the board can point to if it's ever questioned. That's the gap a $199 one-time Board Compliance Kit is built to close: it doesn't replace the licensed engineer or architect who has to perform the SIRS or milestone inspection (that's non-negotiable under state law), but it organizes the deadlines, schedules the follow-up tasks, and gives the board a communication template for explaining funding decisions to owners in plain language. For a board juggling a SIRS deadline, a milestone inspection window, and an annual budget meeting all in the same fiscal year, having one place that tracks what's due and what's already been sent to owners saves a lot of scrambling in March. Whatever tool or process your board uses, the core discipline doesn't change: get the study from a licensed professional, put its numbers into next year's budget, communicate the funding plan to owners well before the vote, and keep a paper trail. Boards that skip the paper trail are the ones who get sued when a special assessment surprises someone.

Frequently asked questions

What is a reserve study?

A reserve study is a professional inspection and financial analysis of a building's major shared components (roof, structure, plumbing, elevators, paving) that estimates remaining useful life and replacement cost, then sets a multi-year funding schedule so the association can pay for repairs without a surprise special assessment.

What is a reserve study for an HOA?

For an HOA, a reserve study inventories common elements like roads, clubhouses, pools, and gates, and projects when each will need major repair. Most Florida HOAs aren't legally required to do one (unlike condos under Chapter 718), but reserve professionals consider it the single best tool for avoiding underfunded special assessments.

What is an HOA assessment?

An HOA assessment is the regular fee owners pay, usually monthly, that funds the association's operating budget and reserve contributions. It's different from a special assessment, which is a one-time extra charge levied when reserves or the operating budget can't cover an unexpected or underfunded cost.

How much should an HOA have in reserves?

There's no universal dollar figure, but reserve professionals use 'percent funded' as the benchmark: 70% or higher is considered strong, 30% to 70% is fair, and below 30% is weak and puts the association at high risk of a special assessment. Florida condo SIRS components now require 100% funding by statute.

How much does a reserve study cost?

Full reserve studies typically run $3,000 to $8,000 for smaller condos and $8,000 to $20,000+ for larger or more complex buildings with elevators or parking structures. Florida's SIRS, which requires a licensed engineer or architect, tends toward the higher end for buildings over 100,000 square feet.

Are HOA special assessments tax deductible?

Generally no, if it's your personal residence. The IRS treats HOA dues and special assessments as nondeductible personal living expenses. Exceptions exist for rental properties (repairs may be deductible; capital improvements add to cost basis). Talk to a CPA about your specific situation.

What is the difference between a milestone inspection and a SIRS?

A milestone inspection (Fla. Stat. § 553.899) is a structural safety check by a licensed engineer or architect, due at 30 years (25 if coastal) and every 10 years after. A SIRS (§ 718.112) is a reserve funding study covering component condition and cost. They're related but separate documents.

Who has to complete a SIRS in Florida?

Condominium and cooperative associations with buildings three stories or higher must complete a Structural Integrity Reserve Study under Fla. Stat. § 718.112. Buildings under three stories and most single-family HOAs are not currently subject to the mandate, though rules can change, so confirm current status with counsel.

Can a board waive reserve funding after a SIRS is completed?

No. Once a condo association completes its SIRS, Fla. Stat. § 718.112(2)(f) prohibits waiving or reducing reserve funding for the structural components the study covers. Owners could previously vote each year to underfund or waive reserves, but that option is now closed for SIRS-covered items.

Who is qualified to perform a Florida SIRS?

Fla. Stat. § 718.112(2)(g) requires the SIRS be performed by someone qualified to conduct it, which DBPR guidance and industry practice interpret as a licensed engineer or architect. Community managers or general contractors can help organize the process but cannot legally certify the study itself.

What happens if a condo board misses its SIRS or milestone inspection deadline?

The association falls out of compliance with state law, which can expose the board to legal claims and complicate reserve funding decisions. The bigger practical risk is financial: deferred maintenance combined with no funding plan is what turns a fixable repair into an emergency, uncapped special assessment.

Does Florida's reserve law apply to HOAs the same way it applies to condos?

No. The SIRS and 100% funding mandate in Fla. Stat. § 718.112 applies to condominiums and cooperatives, not to HOAs governed by Chapter 720. HOAs can and often should run voluntary reserve studies, especially if they maintain shared structures like townhome roofs or parking garages, but it isn't currently a statutory requirement.
