Reserve study: what florida hoas and condos must fund

Last updated 2026-07-24

what is a reserve study

A reserve study is a written report, usually done by a reserve specialist or engineer, that looks at every major shared component in a condo or HOA (roof, paving, painting, elevators, pool, structural elements) and answers two questions: when will this need to be replaced or majorly repaired, and how much will that cost in future dollars. The output is a funding schedule that tells the board how much to put into reserves each year so the money is there when the bill comes due. Most reserve studies have two halves. The physical analysis inventories the components, estimates remaining useful life, and prices out replacement. The financial analysis takes that data and models a funding plan, either "full funding" (target 100% of the theoretical reserve balance) or a lesser "threshold funding" approach that just avoids a zero balance. Florida law increasingly forces the first option for specific structural items. A reserve study is not the same thing as a milestone inspection or a Structural Integrity Reserve Study (SIRS), though people mix these up constantly. A milestone inspection is a one-time structural check tied to a building's age (25 or 30 years depending on coastal location) under Fla. Stat. § 553.899 ^[1]. A SIRS is a recurring reserve study specifically for structural components, required for condos 3 stories and up under Fla. Stat. § 718.112 ^[1]. A general reserve study can cover everything else (roofs, paving, painting) and isn't itself mandated by statute for every association, though most lenders and prudent boards get one anyway.

what is a reserve study for an hoa

For a homeowners association, a reserve study works the same way as for a condo: an inventory of shared components the HOA is responsible for (common-area roofs, clubhouse, pool, gates, roads if privately owned) with a funding plan attached. The difference is legal, not technical. Florida HOAs (governed by Chapter 720 ^[1]) are not required by state law to get a formal, professionally prepared reserve study or to fund reserves at all, unless the HOA's own declaration or bylaws say otherwise. That's a real gap. An HOA board can vote every year to waive or reduce reserve funding, and many do, because underfunding reserves keeps the regular assessment lower and nobody wants to be the board that raised dues. The tradeoff shows up later as a special assessment when the roof fails or the private road needs repaving. See our hoa reserve study guide for the mechanics of getting one done even without a legal mandate. Condos have a much harder rule now. Since the 2022 and 2023 reforms following the Surfside collapse, condo associations 3 stories or taller must complete a SIRS and cannot vote to waive or reduce funding for the structural reserve items it identifies, starting with fiscal year 2025 ^[1]. HOAs still have that waiver option; condos largely don't anymore for structural components.

what is an hoa assessment (and how is it different from a reserve study)

An HOA assessment is the recurring fee owners pay to the association, and a reserve study is the analysis that tells the board how much of that fee (or a separate special assessment) should be going into savings. Regular assessments fund day-to-day operations: landscaping, management fees, insurance, utilities for common areas. Reserve contributions, ideally built into that same regular assessment, fund future big-ticket replacements. A special assessment is a separate, often one-time charge levied when reserves fall short of an actual bill, whether that's a roof replacement, a mandated structural repair, or a fully unplanned failure. Boards that skip or shortchange the reserve study step tend to be the ones hit hardest by special assessments, because nobody saw the number coming. See hoa assessment for a full breakdown of assessment types, and hoa special assessment for how those get triggered and disclosed.

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

There's no single dollar figure that applies to every association; it depends on the number and age of components, size of the property, and construction type. What matters is the percent-funded metric: your actual reserve balance divided by the "fully funded" theoretical balance the reserve study calculates for that point in time. Industry guidance from the Community Associations Institute (CAI) generally treats 70% funded or higher as healthy, 30-70% as adequate but watch closely, and under 30% as "weak" or at high risk of special assessments. There's no Florida statute that sets a universal percent-funded target for all reserve items; the law instead requires that specific SIRS-identified structural components be funded at 100% of the reserve study's recommended level starting with the association's 2025 fiscal year budget, with no board vote allowed to waive or reduce that funding ^[1]. A rough way to sanity-check your own numbers: take the replacement cost of every major component, divide by its remaining useful life in years, and add those figures up. That's your rough annual reserve contribution need, before compounding for inflation in materials and labor (which has run well above general CPI for roofing and concrete work in recent years). If your current reserve line item is a fraction of that number, you're underfunded and a special assessment is a matter of when, not if.

how much does a reserve study cost

A basic reserve study for a small association typically runs somewhere between $1,500 and $5,000, depending on the number of components and whether it includes a site visit versus a desktop update. A full SIRS for a mid-size or larger condo, done by a licensed engineer, tends to run several thousand dollars higher, often $5,000 to $20,000+ for larger buildings with more structural elements to inspect, though pricing varies a lot by region and building complexity and there's no statewide fee schedule published by DBPR. Costs scale with unit count, building height, and how much physical inspection (versus paperwork review) is required. A 3-story, 20-unit building with a straightforward roof and no elevators costs far less to study than a 15-story tower with a parking garage, pool deck, and seawall. Compare that cost to what a deferred repair or emergency special assessment costs owners: post-Surfside special assessments at some Florida condos have run into the tens of thousands of dollars per unit. A few thousand dollars for a reserve study, spread across dozens or hundreds of units, is cheap insurance against getting blindsided. See reserve study for condo association for how to scope and bid the work, and condo special assessment insurance if your board is weighing insurance products meant to soften that blow.

who is legally required to get a reserve study or SIRS in florida

Condo associations with buildings that are 3 stories or higher must have a SIRS completed for each building, per Fla. Stat. § 718.112(2)(g) ^[1]. The statute lists the specific structural components that must be studied: roof, load-bearing walls, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, and windows and exterior doors, among others. The statute is explicit about the funding consequence. It states that reserves for items included in the SIRS "may not be waived or reduced" by the association ^[1]. That's a hard change from the old rule, where a majority of unit owners could vote every year to waive reserve funding entirely. HOAs under Chapter 720 have no equivalent statewide SIRS mandate. Some counties and cities have layered on their own local building recertification rules, most notably Miami-Dade and Broward, which have run 40-year (then 10-year) recertification programs since the 1970s under Miami-Dade County's building recertification ordinance ^[2]. Confirm with your association's counsel and county what applies to your specific building and jurisdiction, because local ordinances can require inspections state law doesn't mention by name.

what happens if a reserve study finds you're underfunded

The reserve study itself doesn't force a fix; it just produces the number. What the board does next is where the legal exposure lives. For condos, once the SIRS identifies structural reserve items, the board has to fund them (no waiver option), which usually means raising regular assessments, levying a special assessment, or in some cases pursuing a loan or line of credit against future assessments. Boards sometimes try to soften the blow by phasing in a large special assessment over several years or pairing it with financing. That's a governance and disclosure decision, not a statutory formula, so any specific structuring should go through the association's counsel and a CPA who understands community association accounting. Owners often ask if a special assessment is deductible on their personal taxes. Generally, no: special assessments for capital improvements or reserve deficits at a residential condo are not deductible as a personal expense under IRS rules, because they're treated as an improvement to your capital asset (the unit), not a deductible cost, unless the unit is a rental property, in which case a portion may be depreciable or deductible as a business expense. This isn't case-by-case tax advice; check with a CPA or see IRS Publication 530, Tax Information for Homeowners ^[3] for how it applies to your situation.

are hoa special assessments tax deductible

Usually not, for a personal residence. The IRS generally treats special assessments the same way it treats the cost basis of home improvements: they add to your basis in the property (which can reduce capital gains tax when you sell) rather than being deductible in the year you pay them ^[3]. That's different from routine HOA dues, which also aren't deductible for a personal residence. The exception is rental or investment property. If you own the condo or home as a rental, a special assessment for a repair may be deductible as a business expense in the year paid, while an assessment for a capital improvement typically has to be depreciated over time rather than deducted all at once, per the depreciation rules in IRS Publication 946, How to Depreciate Property ^[4]. The line between "repair" and "improvement" is a real tax question with real money on both sides of it, so this is a case where a CPA earns their fee. A small carve-out worth checking: if a special assessment was levied specifically for a casualty loss (storm damage, for instance) some owners in federally declared disaster areas may have separate casualty-loss deduction options. That's fact-specific and outside general guidance here; talk to a tax professional.

how do i read a reserve study report

Component inventory	Remaining life & replacement cost per item	Verify against contractor estimates
Percent funded	Current reserves ÷ full funding target	Under 30% signals high special-assessment risk
Recommended annual contribution	$ needed per year to stay funded	Build into next budget cycle
Funding method (full vs. threshold)	How aggressively the plan saves	Full funding required for SIRS items [1]

A typical reserve study report has three parts a board member should actually read closely: the component inventory, the percent-funded figure, and the recommended annual contribution. Skip past the boilerplate methodology section on a first read and go straight to those three numbers. The component inventory lists every reserve item with its estimated remaining useful life and current replacement cost. Check this against reality; if the report says your 2003 roof has 15 years left and your roofer told you last year it needs replacing in 3, get that reconciled before you rely on the funding numbers built on top of it. The percent-funded figure tells you where you stand today relative to the theoretical full-funding target. The recommended annual contribution is the number your budget committee needs to plug into next year's assessment calculation. If the board approves a budget that funds reserves below what the study recommends for SIRS structural items, that's now a statutory problem for condos, more than a prudent-governance one ^[1]. | Report Section | What It Tells You | Board Action |

who can legally perform a reserve study or SIRS in florida

A SIRS for a Florida condo must be performed by a licensed engineer or architect, consistent with the professional licensing structure DBPR oversees for these fields. Boards can't have a property manager or a board member fill this role, and a reserve study company that isn't staffed with the required licensed professional isn't a valid substitute for the structural components covered by SIRS. For the non-structural, general reserve study components (paint, paving, pool furniture, and similar), many associations use a reserve specialist, sometimes credentialed through a program like CAI's Reserve Specialist (RS) designation, though state law doesn't mandate a specific credential for that portion the way it does for the SIRS engineering work. Boards should confirm any firm's licensing status directly through DBPR's license search before signing a contract, and should never let anyone but the licensed professional sign off on the structural findings, no matter how convenient a bundled quote looks.

reserve study vs. milestone inspection vs. SIRS: what's the difference

These three terms get used interchangeably by owners and even some board members, but they're legally distinct and answer different questions. A milestone inspection is a one-time structural safety check required once a condo or co-op building reaches 30 years old (or 25 years if within 3 miles of the coast), then again every 10 years after, under Fla. Stat. § 553.899 ^[1]. It answers: is this building structurally sound right now. A SIRS is a recurring reserve study focused specifically on structural components (roof, load-bearing walls, foundation, and similar) for condos 3 stories and up, required under Fla. Stat. § 718.112 ^[1]. It answers: how much money do we need to save, and by when, to maintain those structural components. A general reserve study covers everything else, roofs aside from structural load-bearing concerns, paving, painting, amenities, and isn't itself a state mandate for every association type, though it's standard practice and often required by an association's own documents or by lenders. It answers: how much should we be saving for the full range of shared property, more than structural risk. Our florida condo reserve fund relief piece covers legislative attempts to soften the post-2024 funding deadlines, which matters if your board is trying to plan a multi-year ramp-up rather than a single shock assessment.

how a board actually uses a reserve study day to day

The reserve study isn't a document you file away after the annual meeting. It's a planning tool that should shape the budget, the capital improvement calendar, and owner communication every year until the next update (most reserve studies get refreshed every 3 to 5 years, or annually for the financial projection piece). A board that's serious about this pulls the recommended annual contribution into the draft budget before members vote, discloses the percent-funded figure in the annual meeting notice, and tracks actual reserve balances against the study's projection at least once a year. That paper trail matters if an owner ever challenges a special assessment or a board's funding decisions later. This is the kind of recurring, unglamorous administrative work that boards let slip, not because anyone's negligent, but because volunteer board members are juggling this alongside jobs and families and the reserve study review always seems to lose out to whatever fire is burning that week. That's the specific gap a fixed-cost tool like our $199 Board Compliance Kit is built for: it organizes the reserve study findings, the SIRS and milestone inspection deadlines, and the required owner notices into one schedule so nothing falls through a busy board's cracks. It doesn't replace the licensed engineer who has to do the actual inspection, and it doesn't tell you whether your reserve funding meets the statute; only your engineer, reserve specialist, and counsel can say that.

Frequently asked questions

What is a reserve study?

A reserve study is a professional analysis of a condo or HOA's shared components (roof, paving, elevators, structural elements) that estimates when each will need replacement and how much money the association should save annually to pay for it. It has a physical inventory and a financial funding plan. Florida condos 3+ stories must get the structural version, called a SIRS, under Fla. Stat. § 718.112.

What is a reserve study for an HOA?

For an HOA, a reserve study inventories common-area components the association owns (clubhouse, pool, private roads, gates) and sets a savings schedule for their eventual replacement. Unlike condos, Florida HOAs under Chapter 720 aren't statutorily required to get one or fully fund it, unless their own governing documents say so.

What is an HOA assessment?

An HOA assessment is the fee owners pay the association, either as a recurring regular assessment covering operations and reserves, or as a special assessment levied to cover a specific, often unbudgeted, cost. A reserve study is what tells the board how much of the regular assessment should go toward reserves.

How much should an HOA have in reserves?

There's no single required dollar figure; it depends on your reserve study's component list and replacement costs. Industry guidance from CAI treats 70%+ funded as healthy and under 30% as high-risk for special assessments. Florida condos must fund SIRS structural items at 100% of the study's recommendation starting fiscal year 2025, with no waiver option.

How much does a reserve study cost?

A basic reserve study for a small association often runs $1,500 to $5,000. A full engineering-based SIRS for a larger condo can run $5,000 to $20,000 or more, depending on unit count, building height, and structural complexity. Costs vary regionally; there's no statewide DBPR fee schedule.

Are HOA special assessments tax deductible?

Generally no, for a personal residence. The IRS typically treats special assessments as adding to your property's cost basis rather than as a deductible expense. If the unit is a rental property, a portion may be deductible as a repair expense or depreciated as a capital improvement; check with a CPA.

What's the difference between a reserve study and a SIRS?

A reserve study can cover any shared component (roofs, paint, pools, paving). A SIRS (Structural Integrity Reserve Study) is a specific, statutorily required subset focused only on structural components, mandatory for Florida condos 3 stories and up under Fla. Stat. § 718.112, with no funding waivers allowed.

Is a reserve study the same as a milestone inspection?

No. A milestone inspection is a one-time structural safety check required at 25 or 30 years of building age (depending on coastal distance) under Fla. Stat. § 553.899. A reserve study or SIRS is about funding future repairs, not certifying current structural safety, though both often use similar engineering findings.

Who has to get a SIRS in Florida?

Condo associations with buildings 3 stories or taller must complete a Structural Integrity Reserve Study for each qualifying building, per Fla. Stat. § 718.112(2)(g). Florida HOAs have no equivalent statewide requirement, though local county or city ordinances may impose separate structural inspection or recertification rules.

Can a board vote to skip or reduce reserve funding?

For SIRS structural components in condos, no; the statute says that funding 'may not be waived or reduced' starting with the 2025 fiscal year budget. For general (non-SIRS) reserve items and for most HOAs under Chapter 720, boards or members can often still vote to waive or reduce funding, depending on governing documents.

What happens if my association doesn't have enough in reserves?

The association typically has to make up the shortfall through a special assessment, a loan, or a phased multi-year assessment increase. For condos, SIRS-identified structural shortfalls can't legally be ignored or waived going forward, which is pushing many buildings toward larger, faster assessments than owners expected.

Who is qualified to perform a reserve study or SIRS?

A SIRS must be performed by a licensed engineer or architect. General reserve study work for non-structural components is often done by a credentialed reserve specialist, though state law doesn't mandate a specific credential for that portion. Verify any provider's license through DBPR before hiring.
