What is a reserve study for condominiums, and why it matters

Last updated 2026-07-24

What is a reserve study?

A reserve study is a written report that inventories the big-ticket physical components of a condo or HOA property (roofs, elevators, pools, pavement, painting, structural elements) and estimates two things: how many years each one has left, and what it will cost to repair or replace when that time comes. The study then recommends a funding plan, usually a schedule of annual contributions, so the money is sitting in the reserve account when the bill actually arrives. Most studies have two parts. The physical analysis walks the property, documents component condition, and estimates useful life and remaining useful life. The financial analysis takes that data and current reserve balances and models a funding plan, either "full funding" (aiming to keep reserves at or near 100% of the ideal balance) or "threshold funding" (keeping the account above a minimum floor, often zero, without ever fully funding). In Florida, this isn't just best practice anymore. Florida Statutes section 718.112 requires condo associations to maintain reserves based on a reserve study for certain components, and separately requires a Structural Integrity Reserve Study (SIRS) for buildings three stories or higher, covering specific structural items ^[1]. The SIRS is narrower than a traditional full reserve study (it focuses on load-bearing and life-safety components) but it carries legal weight that a voluntary study doesn't: waiving or reducing SIRS-based reserves is no longer allowed for the components it covers ^[1]. For a plain walkthrough of how the report gets built and who can prepare it, see reserve study.

What is a reserve study for an HOA (as opposed to a condo)?

A reserve study for an HOA covers the same basic idea, an inventory of shared components and a savings plan, but the legal requirements are different from condos. Florida's mandatory Structural Integrity Reserve Study under Chapter 718 applies to condominiums, not single-family HOAs. HOAs (homeowners associations governing detached houses or townhomes) are covered under Chapter 720, which has its own, generally lighter, reserve disclosure rules ^[2]. That doesn't mean HOA reserve studies are optional in practice. If an HOA maintains a clubhouse, pool, private roads, retaining walls, or a gate system, a reserve study is still the only real way to know if dues are set correctly. Underfunded HOA reserves show up later as special assessments, the same way they do in condos, just without the statutory SIRS trigger forcing the issue. Boards sometimes ask whether a cookie-cutter HOA reserve template is good enough. It usually isn't. A generic study built for a 40-unit townhome community with asphalt roads and vinyl siding will miss the specific components (a private lift station, a marina, a shared seawall) that actually drive an individual community's costs. For a Florida-specific breakdown of what belongs in an HOA study, see hoa reserve study.

How much does a reserve study cost?

Full reserve study (all components)	$3,000-$15,000+	Every major shared component, funding plan
SIRS (structural components only)	Often bundled into engineering fees, varies widely	Roof, load-bearing walls, floor, foundation, and other structural items listed in statute
Update/desktop study	$1,000-$5,000	Refreshes cost and life estimates without a full new inspection	For the deadline pressure that's driving a lot of these studies right now, see reserve study for condo association.

Reserve study costs in Florida generally run from about $3,000 to $15,000 or more, depending on the number of components, the size and age of the property, and whether it includes a full physical inspection or a desktop update. A small mid-rise condo with a straightforward component list might land near the low end. A large coastal high-rise with elevators, a seawall, multiple pools, and structural elements typically costs more, sometimes well into five figures once engineering fees for the SIRS structural portion are added. There's no statewide fee schedule and no single "official" number, so treat any quote as building-specific. Get at least two or three proposals and ask exactly what's included: is this a full study with a site visit and component-by-component inspection, or an update study that reuses prior data? Update studies (typically done every few years between full studies) cost less but are only as good as the baseline data behind them. One cost-saving note worth understanding: a SIRS inspection and a milestone inspection cover some overlapping ground (structural condition of the building), but they are legally distinct reports required under different statutory sections, and in most cases you'll need both. Some engineering firms will bundle site visits to reduce travel and inspection duplication, which can meaningfully lower the combined bill. Ask your inspector directly whether bundling is possible for your property. | Study type | Typical cost range | What it covers |

How much should an HOA (or condo) have in reserves?

There's no single magic number, and anyone who tells you a flat percentage of the annual budget is oversimplifying. The honest answer: an association should have enough in reserves to match what its own reserve study says it needs, based on the actual age and remaining life of its actual components. A 5-year-old building and a 35-year-old building with identical unit counts can have wildly different reserve needs. That said, industry practitioners and reserve specialists commonly use "percent funded" as a benchmark: reserves divided by the fully-funded ideal balance for where components currently stand in their life cycle. Associations below roughly 30% funded are generally considered at higher risk of a special assessment or a jump in dues, while those above 70% are usually in reasonably good shape. These are professional rules of thumb from the reserve-study industry, not statutory thresholds, so don't treat them as legal minimums. What Florida law does now require for condos: for the SIRS components (roof, structure, waterproofing, electrical, plumbing, load-bearing walls, and others listed in section 718.112), associations generally cannot vote to waive or underfund reserves once a SIRS has been completed ^[1][3]. As the statute puts it, reserve funds for items covered by a milestone-triggered SIRS "may not be waived or reduced" by member vote for those components ^[1]. For everything outside the SIRS list, boards and members still retain more flexibility, though that flexibility is narrower than it was before 2022. If your building has never had a reserve study, don't guess at a savings number and hope it's close. Get the study done first; the funding target follows from that data, not the other way around.

What is an HOA assessment, and what is an HOA special assessment?

An HOA assessment (sometimes just called "association assessments" or "dues") is the regular fee owners pay, usually monthly or quarterly, to fund operating expenses and reserve contributions. It's set by the board (often within limits set by the governing documents) based on the annual budget. A special assessment is different: it's a one-time (or occasionally installment) charge levied outside the regular budget cycle, usually because reserves are insufficient to cover an unexpected or underfunded expense, like a roof replacement that came due faster than planned, storm damage not fully covered by insurance, or a large capital project identified by a milestone inspection or SIRS. Special assessments are legal in Florida condo and HOA associations when authorized under the governing documents and Chapter 718 or 720, but they are also the single biggest source of owner anger and litigation risk boards deal with. The practical link between reserve studies and special assessments is direct and worth saying plainly: a well-funded reserve account, built off a realistic reserve study, is what prevents special assessments in the first place. Boards that skip or underfund the study almost always end up facing a special assessment eventually, usually at the worst possible time (right after a big repair becomes urgent, not before). For a deeper look at how these get structured and communicated to owners, see hoa special assessment.

Are HOA special assessments tax deductible?

Generally, no, not for the individual owner's personal tax return, at least not as a straightforward deduction the way property taxes are. The IRS treats most HOA and condo assessments, including special assessments, as personal living expenses when the property is your primary residence, and personal living expenses aren't deductible ^[4]. There are narrow exceptions. If the unit is a rental property, special assessments may be deductible as a business expense or, if they're for a capital improvement (rather than a repair), added to the property's cost basis and depreciated over time. If part of a special assessment is specifically for casualty-loss repair after a federally declared disaster, there can be limited casualty-loss treatment, but the rules are technical and have shifted since the Tax Cuts and Jobs Act changed personal casualty-loss deductions ^[4][5]. This isn't tax advice, and boards shouldn't try to answer this question for owners. The honest, useful thing a board can do is tell owners clearly what the assessment is for (repair vs. capital improvement, and whether it relates to a declared disaster) and point them to a CPA. IRS Publication 530 is a reasonable starting reference for owners asking ^[5].

How is a reserve study different from a milestone inspection or SIRS?

These three things get confused constantly, and the confusion causes real scheduling and budget mistakes, so it's worth being precise. A milestone inspection is a structural safety inspection required for condo and cooperative buildings three stories or more in height, under Florida Statutes section 553.899, generally due by the building's 30th year (or 25th year if within three miles of the coast), and every 10 years after ^[6]. It's performed by a licensed architect or engineer and produces a report on structural safety, not a funding plan. A Structural Integrity Reserve Study (SIRS) is a reserve-specific study required under section 718.112, generally triggered once a building reaches the milestone inspection threshold, that looks at the same categories of structural components but produces a cost and funding schedule, not a pass/fail safety verdict ^[1]. A reserve study (full/traditional) is the broader, non-statutory-mandatory category that covers all major shared components, structural and non-structural alike (paint, pavement, pool equipment, elevators), and produces a full funding plan for the whole property, more than the SIRS list. In practice, most buildings 3+ stories now need all three at different points: the milestone inspection for life-safety compliance, the SIRS for structural reserve funding, and (often voluntarily, though smart boards do it anyway) a full reserve study to cover everything the SIRS doesn't touch. For how these deadlines actually stack up by building age, see reserve study and the milestone inspection guides on this site.

Who performs a reserve study, and who is qualified to do a SIRS?

A traditional reserve study is typically prepared by a reserve study specialist, sometimes credentialed through professional bodies like the Community Associations Institute, though Florida doesn't license "reserve study" as a standalone profession the way it licenses engineers ^[7]. A SIRS, because it involves structural components tied to building safety, must be performed or supervised by a licensed engineer or architect under Florida law, per section 718.112 ^[1]. Boards should verify credentials directly through Florida's Department of Business and Professional Regulation license search before signing a contract . This matters because a cut-rate "reserve study" from an unlicensed provider that skips proper structural evaluation won't satisfy the SIRS requirement, and the board could end up paying twice: once for the inadequate report, and again for the real one. Confirm scope and licensing in writing before the site visit, not after.

How often does a reserve study need to be updated?

There's no single statewide statutory update interval for a traditional reserve study the way there is for milestone inspections (every 10 years) or SIRS (tied to the milestone cycle). Industry practice generally recommends a full reserve study every 3 to 5 years, with lighter update studies in the years between, since component costs, inflation, and remaining useful life estimates all drift over time. For SIRS specifically, because it's now tied to the milestone inspection schedule under section 718.112, associations should expect to refresh the structural reserve numbers roughly on the same 10-year cycle as the milestone inspection, though a material change (major storm damage, a large unexpected repair, a big jump in construction costs) is a good reason to update sooner regardless of the calendar. Boards that let a reserve study go stale for eight or ten years without any update are usually the ones blindsided by a special assessment. Costs move; a study built on five-year-old material and labor pricing understates what the actual project will cost today.

How do boards actually use a reserve study day to day?

The report itself is only useful if the board actually works from it. In practice that means three things: setting the annual budget's reserve line item to match (or explain a documented deviation from) the study's funding schedule, tracking which components are approaching end-of-life so bids can go out before there's an emergency, and communicating the numbers to owners before assessment season, not during it. A lot of board turnover and owner frustration in Florida right now traces back to boards that had the reserve study sitting in a file but never translated it into a real budget line or a homeowner-facing timeline. That's less a legal problem than an organizational one, and it's exactly the gap a $199 one-time Building-Specific Board Compliance Kit is built to close: it takes the reserve study and milestone/SIRS deadlines a licensed professional already produced and turns them into a scheduled, board-ready compliance calendar and owner communication packet. It doesn't replace the engineer or the reserve specialist, and it doesn't render any verdict on whether a specific building complies with anything; it organizes what the professionals already delivered so the board doesn't lose the thread between reports. You can build one at /board-kit-builder. Whatever tool a board uses, the core discipline is the same: read the study, put its numbers into the budget, and revisit both every year, more than when a deadline forces the issue.

What happens if an association skips or ignores its reserve study?

For SIRS specifically, skipping it isn't really an option anymore for condo buildings 3+ stories once they hit the milestone threshold; section 718.112 makes the SIRS and its reserve-funding consequences mandatory, and associations that don't comply risk both legal exposure and, more practically, a much bigger financial hole when deferred repairs finally come due ^[1][3]. For a traditional (non-SIRS) reserve study, there's less direct statutory enforcement, but the real-world consequence is the same either way: components fail on their own schedule regardless of whether the association planned for it. Boards that skip the study tend to find out what a roof or elevator replacement really costs at the worst possible moment, usually via a large special assessment vote that owners didn't see coming and often can't easily afford. County-level building departments and lenders are also increasingly asking for reserve study and SIRS documentation before approving permits or financing, particularly after the 2021 Champlain Towers South collapse in Surfside prompted the current wave of Florida legislation ^[3]. A building without current reserve documentation can find itself stuck when an owner tries to sell or refinance, since Fannie Mae's condo project review guidelines now ask lenders to confirm whether an association has completed a required structural inspection and reserve study .

Frequently asked questions

What is a reserve study in simple terms?

It's a report, usually from an engineer or reserve specialist, listing a property's major shared components, how many years each has left, and what it will cost to fix or replace them. It ends with a savings schedule so the association isn't caught short when something big needs replacing.

What is a reserve study for an HOA specifically?

For an HOA (as opposed to a condo), it's the same basic report applied to shared amenities like roads, pools, clubhouses, and gates. HOAs fall under Florida Chapter 720 rather than the condo-specific Chapter 718 SIRS requirement, so the legal obligation to have one is generally lighter, but the financial logic is identical.

How much does a reserve study cost in Florida?

Typically $3,000 to $15,000 or more, depending on property size, component count, and whether it's a full study or an update. Large coastal high-rises with structural (SIRS) components usually land at the higher end once engineering fees are included.

How much should a condo or HOA have in reserves?

Enough to match its own reserve study's funding schedule, not a generic percentage. Industry practitioners often use "percent funded" as a rough benchmark, with under 30% considered high risk and over 70% considered healthy, but these are professional guidelines, not Florida statutory minimums.

What is an HOA assessment versus a special assessment?

A regular assessment is the ongoing dues owners pay to fund the operating budget and reserves. A special assessment is a one-time (or installment) charge outside the normal budget, usually to cover a shortfall or unexpected repair the reserve fund didn't cover.

Are HOA or condo special assessments tax deductible?

Generally no for a primary residence; the IRS treats them as personal living expenses. Exceptions can apply for rental property (as a business expense or added to cost basis) or in limited casualty-loss situations tied to a federally declared disaster. Owners should confirm specifics with a CPA.

Is a reserve study the same as a SIRS?

No. A SIRS (Structural Integrity Reserve Study) is a specific, statutorily required subset focused only on structural and life-safety components under Florida Statutes 718.112. A full reserve study covers everything, structural and non-structural, and isn't itself mandated by that statute.

Is a reserve study the same as a milestone inspection?

No. A milestone inspection (Florida Statutes 553.899) is a structural safety inspection performed by a licensed engineer or architect, generally due by year 30 (or year 25 near the coast). A reserve study or SIRS produces a funding plan, not a safety pass/fail determination.

Who is legally required to perform a SIRS in Florida?

A SIRS must be performed or supervised by a licensed engineer or architect under Florida Statutes 718.112. Boards should verify licensing through Florida's Department of Business and Professional Regulation before hiring anyone for this work.

How often should a reserve study be updated?

Industry practice generally recommends a full study every 3 to 5 years with lighter updates in between. SIRS updates typically follow the same roughly 10-year cycle as the milestone inspection, though major storm damage or big cost changes are good reasons to update sooner.

Can a Florida condo association waive its reserve requirements?

For SIRS-covered structural components, generally no; the law now prohibits waiving or reducing those reserves by member vote once a SIRS applies. For non-SIRS components, associations may still have more flexibility, but boards should confirm current rules with association counsel since this area has changed multiple times since 2022.

What components does a Florida SIRS have to cover?

Florida Statutes 718.112 lists categories including roof, load-bearing walls and other primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, and waterproofing and exterior painting, among others specified in the statute. Confirm the current list with your association's engineer, since amendments have adjusted details over time.
