What is a reserve study for an HOA? Florida guide

Last updated 2026-07-24

what is a reserve study?

A reserve study is a two-part report. First, an inspector or engineer looks at the building's major shared components, roof, paving, painting, elevators, pool decking, structural elements, and estimates how many years each one has left before it needs replacement or major repair. Second, a financial analyst uses those useful-life estimates to calculate how much money the association should be setting aside each year so the cash is there when the bill comes due. Think of it as a long-range maintenance budget with an engineering backbone. Instead of guessing that "the roof will probably need doing sometime in the next decade," a reserve study says the roof has an estimated remaining useful life of 7 years, will cost roughly $180,000 to replace, and the association needs to be contributing a specific dollar amount per year to hit that number without a special assessment. Most reserve studies get updated every 3 to 5 years, with a lighter "update" review in between full studies, because material costs, interest rates, and actual component wear don't stay static. A study done in 2019 using pre-pandemic concrete and labor pricing is not a document you want to rely on in 2026. For Florida condos, this isn't just good practice anymore. Milestone inspection findings and Structural Integrity Reserve Study (SIRS) requirements under Fla. Stat. § 718.112 now tie reserve funding directly to actual inspection results for buildings three stories and taller.

what is a reserve study for an HOA?

For a homeowners association (as opposed to a condo), a reserve study covers the shared amenities the HOA is legally responsible to maintain: private roads, clubhouse, pool, gates, retention ponds, community signage, and shared irrigation systems. It does not typically cover anything inside individual homes, since those are usually owned and maintained by the homeowner, not the association. Florida law treats HOAs differently from condos on this point. Fla. Stat. § 720.303(6) allows HOA reserves, but membership can vote to waive or reduce reserve funding annually unless the governing documents say otherwise. Condos lost most of that flexibility for structural reserve items after the 2022 legislative changes following the Surfside collapse. That distinction matters a lot when boards ask "do we have to do this" versus "should we do this." Even where it isn't strictly mandatory, an HOA reserve study is one of the cheapest ways to avoid a five-figure special assessment landing on owners with no warning. A reserve study for condo association and a straight HOA reserve study follow similar methodology, but the legal funding obligations differ, and your board attorney should confirm which rules apply to your specific documents and county.

what is an HOA assessment?

An HOA assessment is money owners are required to pay the association, on top of or instead of a purchase price, to cover shared costs. There are two basic kinds. Regular (or "annual") assessments are the recurring dues every owner pays, usually monthly or quarterly, covering routine operating costs like landscaping, insurance, management fees, and reserve contributions. Special assessments are one-time, extra charges levied when the regular budget can't cover a cost, usually a big unplanned repair, an insurance premium spike, or a reserve shortfall the association didn't save enough for. If the roof reserve fund only has $40,000 saved but the new roof costs $220,000, the board typically levies a special assessment to cover the gap. See our detailed breakdown on HOA special assessment rules, notice requirements, and how boards are supposed to calculate the amount owed per unit.

how much should an HOA have in reserves?

There's no single dollar figure or percentage that applies everywhere, and anyone who gives you a flat answer like "you need 3 months of budget" is oversimplifying. The right amount depends entirely on your reserve study: the age of your components, their replacement cost, and how many years of useful life remain. A rough industry benchmark used by some reserve specialists is the "percent funded" ratio, comparing what's actually in reserves to what should be there based on component depreciation. Community Associations Institute (CAI) materials generally describe funding below 30% as "weak" and above 70% as "strong," though CAI does not publish a single universal target percentage that fits every association. For Florida condominiums 3+ stories, the math is no longer optional guesswork. Under current law, associations must fund reserves for items covered by the SIRS at 100% of the fully funded amount, without the option to waive or underfund those specific line items, starting with budgets adopted on or after December 31, 2024 ^[1]. Non-structural reserve items (painting, landscaping, etc.) can still be voted to waive or reduce in many cases, depending on your documents; confirm with counsel.

how much does a reserve study cost?

For a typical HOA or small condo association, a full reserve study from a qualified provider generally runs $3,000 to $8,000, depending on the number of components, property size, and whether it's a first-time study or an update. Larger or more complex properties, especially high-rise condos with elevators, structural systems, and extensive amenities, can run $10,000 to $20,000 or more. Update studies (no new site visit, just recalculated numbers) cost less, often $1,000 to $3,000, and are typically done in the years between full studies. Compare that to the cost of getting it wrong. A special assessment to cover an unfunded roof or structural repair on a mid-size condo building can easily run $10,000 to $50,000 per unit. A few thousand dollars spent on an accurate reserve study is cheap insurance against that outcome, and it gives the board a defensible paper trail if an owner challenges the assessment later. SIRS-specific inspections in Florida (the structural component study required by § 718.112) must be performed by a licensed engineer or architect ^[1], and costs for that portion vary by building size and complexity; DBPR does not publish a fixed fee schedule, so get quotes from at least two licensed providers.

what are HOA assessments used for?

Regular assessments fund the everyday running of the community: landscaping contracts, common-area utilities, property insurance, management company fees, pool maintenance, and the reserve contribution line item itself. Special assessments fund the gap between what's needed and what's saved, most often for big-ticket items: roof replacement, repaving, structural repairs identified in a milestone inspection, elevator overhauls, or storm damage not fully covered by insurance. Boards are generally required to give written notice of a proposed special assessment before the vote, and many governing documents (plus statute, depending on structure) require the notice to include the purpose and estimated amount. If you're facing one, read the notice carefully; it should tie back to a specific reserve shortfall or repair need, ideally one your reserve study already flagged.

are HOA special assessments tax deductible?

Generally, no, not for the individual homeowner claiming it as a personal itemized deduction. The IRS treats HOA assessments, regular or special, as a personal living expense similar to homeowners insurance or utility bills, which are not deductible on a primary residence ^[2]. There are two narrow exceptions worth knowing. If the property is a rental or investment property, special assessments may be deductible as a business expense or added to the property's cost basis, depending on whether the assessment is for repairs (deductible) or a capital improvement (depreciated over time). And if a special assessment is specifically for a federally declared disaster-related casualty loss, there may be limited casualty-loss deduction treatment under IRS rules, though the Tax Cuts and Jobs Act narrowed casualty loss deductions significantly for 2018 through 2025 ^[3]. This is genuinely a case-by-case tax question. Talk to a CPA who knows real estate before assuming either way, especially if you own a rental unit or the assessment followed hurricane damage.

what triggers a required reserve study or SIRS in Florida?

Florida condominium buildings that are three stories or more in height must have a Structural Integrity Reserve Study completed, and the statute sets recurring deadlines tied to the building's age and milestone inspection cycle ^[1]. This requirement grew directly out of the 2021 Champlain Towers South collapse in Surfside and the legislative response that followed (SB 4-D, later codified into Chapter 718). The SIRS must be performed or overseen by a licensed engineer or architect and must, at minimum, address the load-bearing structural components identified in the statute: roof, structure, load-bearing walls, floor, foundation, fireproofing/fire protection systems, plumbing, electrical, and waterproofing, among others listed in § 718.112(2)(g) ^[1]. HOAs (non-condo, single-family or townhome communities under Chapter 720) are not currently subject to the SIRS mandate. That requirement is specific to condominiums and cooperatives under Chapter 718 and 719. If your community isn't a condo, don't assume SIRS applies; check your entity type and confirm with your association's counsel.

who actually performs a reserve study, and who checks the math?

For the physical/engineering component (the SIRS specifically), Florida law requires a licensed engineer or architect to do the visual inspection and structural assessment ^[1]. You can verify a professional's license status through the Florida Department of Business and Professional Regulation's licensee search tool ^[4] before signing a contract. For the broader financial reserve study (useful life estimates, funding plan, percent-funded calculations), many associations hire a reserve study specialist, sometimes credentialed through organizations like CAI's Reserve Specialist (RS) designation, though Florida doesn't currently license "reserve study" as its own separate profession the way it licenses engineers. The board's job isn't to do the inspection. It's to hire qualified people, get competing quotes, review the resulting report critically, and then actually act on the funding numbers instead of shelving the report in a drawer. Boards that skip that last step are the ones facing six-figure special assessments a few years later.

how does a reserve study connect to the milestone inspection?

The milestone inspection and the SIRS are related but separate requirements, and boards sometimes conflate them. The milestone inspection is a structural safety check, required at 25 or 30 years depending on coastal proximity, then every 10 years after, focused on whether the building is structurally sound right now ^[5]. The SIRS is the forward-looking financial planning document: given what the milestone inspection (and other inspections) found, how much should the association be saving, starting now, to pay for the repairs those structural systems will eventually need? A milestone inspection can flag a structural problem; the SIRS is what tells the board how to fund fixing it before it becomes an emergency. Boards juggling both processes at once often lose track of which report is due when, and to which county office. A board compliance kit built for your building's specific age and height can help keep milestone deadlines, SIRS renewal dates, and reserve budget votes on one calendar instead of scattered across emails and old board meeting minutes. It's a $199 one-time organizing tool, not a substitute for the licensed engineer or reserve specialist doing the actual inspection work.

what happens if an association skips or underfunds its reserve study?

For Florida condos subject to the SIRS mandate, failing to complete the study or underfunding the required structural reserve line items isn't just a bad idea, it's a statutory compliance failure that can expose board members to liability claims and expose the association to enforcement action or difficulty securing insurance and financing. Lenders have started paying close attention. Fannie Mae maintains condo project eligibility requirements that factor in reserve adequacy, deferred maintenance, and unresolved structural or safety inspection findings; a building flagged with significant deferred maintenance or unfunded repairs can end up ineligible for standard financing, which makes units in that building harder to sell or refinance ^[6]. Practically speaking, the immediate risk to owners is the special assessment itself. An association that never did a reserve study, then gets hit with a $2 million roof and structural repair bill, has to spread that cost across all owners at once, often with 30 to 60 day payment windows written into the governing documents. Compare that to spreading the same $2 million over 10 years of planned reserve contributions. The difference is the entire point of doing the study in the first place.

Frequently asked questions

What is a reserve study in simple terms?

It's a report that looks at everything a community owns in common, roofs, pools, roads, elevators, and estimates when each item will wear out and how much it will cost to fix or replace. Then it calculates how much money the association should save each year so that cost doesn't show up as a surprise bill to owners.

Is a reserve study the same as a milestone inspection?

No. The milestone inspection checks whether a building's structure is currently sound, required at 25 or 30 years and every 10 years after under Fla. Stat. § 553.899. The reserve study (or SIRS) is the financial planning piece: how much to save based on what condition those components are in and how long they'll last.

How much should an HOA keep in reserves?

There's no universal dollar figure; it depends on your specific components' age, condition, and replacement cost per your reserve study. As a rough industry gauge, some reserve specialists consider funding below 30% of the fully-funded target 'weak' and above 70% 'strong,' though this varies by association and property type.

Do all Florida HOAs need a reserve study?

No. The Structural Integrity Reserve Study mandate under Fla. Stat. § 718.112 applies to condominiums and cooperatives 3+ stories, not standard homeowners associations under Chapter 720. HOAs can still choose to do reserve studies voluntarily, and many should, but it isn't currently a statutory requirement the way it is for condos.

How much does an HOA reserve study cost?

Typically $3,000 to $8,000 for a standard HOA or small condo, and $10,000 to $20,000-plus for larger high-rise properties with complex systems. Update studies (no new inspection, recalculated figures only) usually cost $1,000 to $3,000. Get at least two quotes; pricing varies a lot by region and provider.

Are HOA special assessments tax deductible?

Generally no, for a primary residence the IRS treats them as a nondeductible personal expense. Exceptions may apply for rental/investment properties (as a business expense or basis addition) or in limited federally-declared disaster casualty loss situations. Talk to a CPA about your specific situation before assuming either way.

What's the difference between a regular assessment and a special assessment?

A regular assessment is the recurring dues (monthly or quarterly) covering routine operating costs and reserve contributions. A special assessment is a one-time extra charge levied when the regular budget or reserves can't cover a cost, usually a major unplanned repair or a reserve shortfall.

Who has to perform a SIRS in Florida?

The structural portion must be performed by a licensed engineer or architect, per Fla. Stat. § 718.112(2)(g). You can verify a professional's active license through the Florida DBPR licensee search tool before hiring anyone for this work.

How often does a reserve study need updating?

Most reserve specialists recommend a full study every 3 to 5 years, with lighter update reviews in between. Costs, interest rates, and actual wear on components change enough over that window that an older study's numbers become unreliable for setting current-year reserve contributions.

Can a Florida condo association waive its SIRS reserve funding?

No, not for the structural components covered by the SIRS. Since budgets adopted on or after December 31, 2024, those specific reserve line items must be funded at 100% of the calculated amount; owners can no longer vote to waive or reduce them. Confirm current requirements with your association's counsel, since this area has seen legislative amendments.

What components does a SIRS have to cover?

At minimum: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, and waterproofing, per Fla. Stat. § 718.112(2)(g). The statute lists these as the required structural items; associations can include additional components beyond the statutory minimum.

What happens if my association never did a reserve study?

You're more likely to face a large, sudden special assessment when a major component fails or is flagged in a milestone inspection, since there's no savings cushion built up gradually. For SIRS-required Florida condos, skipping it is also a statutory compliance gap that can affect insurability and mortgage eligibility for units in the building.
