TL;DR
A reserve study is a report that lists every major common-element component (roof, paint, pavement, elevators, structure), its remaining life, and the replacement cost, then calculates what the association should save each year. Florida condos over three stories must also get a Structural Integrity Reserve Study (SIRS) under Fla. Stat. 718.112(2)(g), and boards fund those line items at 100%, no more waivers or pooling for that subset [1].
what is a reserve study for a condo association
A reserve study is a financial and physical inspection report. It lists every major component the association owns (roof, painting, paving, pool resurfacing, elevators, structure, plumbing risers, whatever your building has), estimates how many years each one has left, prices out replacement or major repair, and then builds a savings schedule so the money is there when the bill comes due. Think of it as two documents stapled together. Part one is a component inventory: what you own, its age, its condition, and its useful life. Part two is a funding plan: how much cash you need in the bank this year, next year, and every year after that, so a $900,000 roof replacement in year 14 doesn't turn into a surprise $6,000-per-unit special assessment in year 13. Most studies run 20 to 30 years out. A licensed reserve specialist, engineer, or in some cases a qualified inspector does the physical inspection and cost estimating. Florida law doesn't require a specific license for a standard association reserve study, but for the Structural Integrity Reserve Study required on buildings over three stories, the inspection portion has to be done by a licensed engineer or architect [1]. For a walkthrough of the statute's actual mechanics, see our reserve study explainer and the companion reserve study for condo association page.
what does a sample reserve study actually contain
| Roof (flat, built-up) | 6 | $780,000 | $130,000 | |
|---|---|---|---|---|
| Exterior painting | 4 | $145,000 | $36,250 | |
| Parking lot resurfacing | 9 | $210,000 | $23,333 | |
| Pool resurfacing/equipment | 5 | $65,000 | $13,000 | |
| Elevator modernization | 12 | $340,000 | $28,333 | |
| Structural (SIRS items, combined) | 22 | $1,150,000 | $52,272 | Those numbers are illustrative, not a template to copy. Your building's actual costs depend on square footage, region, contractor bids, and current material pricing. Never use a sample table as a substitute for your own study. |
If you pull up a real reserve study, structured properly, it has five parts, in this order. 1. Executive summary. One or two pages. Current reserve balance, percent funded, recommended annual contribution, and a plain-English flag for anything urgent (like a roof at 90% of its useful life). 2. Component inventory table. Every major common element, individually. A typical mid-rise might list 25 to 40 line items: roof (by section if the building has more than one roof type), exterior paint, sealants, pavement/parking, pool and equipment, elevators (cab interior vs. mechanical separately), fire pump, generator, seawall or dock if waterfront, and, since 2022, the SIRS-mandated categories: roof, load-bearing walls, floor, foundation, fireproofing/fire protection systems, plumbing, electrical, waterproofing, and exterior painting/sealants [1]. 3. Condition assessment and remaining useful life (RUL) for each item, in years, based on the inspector's visual review and sometimes destructive or non-destructive testing for structural items. 4. Cost estimate for replacement or major repair, in current dollars, usually with an inflation assumption noted (many Florida studies use 3% to 4% annual construction cost inflation, though the study should state its own assumption rather than you guessing). 5. Funding plan, either straight-line (equal annual deposits) or component method (cash-flow, funds each item separately), showing the projected reserve balance every year for 20 to 30 years against the projected expenditures. Here's a simplified sample table format, the kind you'd see in an actual study: | Component | Est. remaining life (yrs) | Current replacement cost | Annual reserve contribution |
what is a reserve study for an hoa
For a homeowners association (as opposed to a condominium), a reserve study covers the common elements the HOA itself owns and maintains, typically things like the clubhouse roof, pool, gated entry, private roads, retention ponds, and shared recreational amenities. Single-family HOAs generally don't own the individual homes' roofs or structures, so the component list is shorter than a condo's. Florida's mandatory SIRS requirement under Fla. Stat. 718.112 applies specifically to condominiums (and cooperatives under a parallel provision), not to HOAs, so a homeowners association reserve study is usually voluntary unless the HOA's own declaration requires one [1]. That said, plenty of HOA boards commission one anyway, because underfunded reserves are the single most common reason for surprise special assessments in any community association, HOA or condo. If your community is an HOA weighing whether to do a formal study or just estimate reserves internally, the math still works the same way: inventory the shared assets, estimate remaining life, price replacement, and build an annual savings number. See our hoa reserve study page for the HOA-specific version of this process.
what is an hoa assessment (and what is a special assessment)
An HOA assessment is simply the money owners are required to pay their association, most commonly a regular monthly or quarterly fee that covers operating costs and reserve contributions. A special assessment is a separate, one-time charge levied when the regular budget can't cover an unexpected or underfunded cost, like an emergency roof replacement or a post-Surfside structural repair mandated by an engineer's report. Regular assessments are budgeted, predictable, and (in most declarations) capped by percentage increases the board can approve without a full membership vote. Special assessments are the opposite: unbudgeted, often large, and sometimes require a supermajority owner vote depending on the declaration and Chapter 718's provisions on material alterations versus maintenance. The direct link between reserve studies and special assessments is this: a well-funded reserve, built from a good study, is what keeps a board from ever having to levy a large special assessment in the first place. Boards that skip or underfund reserves are the ones calling emergency meetings to explain a five-figure bill per unit. For the mechanics of how a special assessment gets approved, noticed, and collected in Florida, see hoa special assessment.
how much should an hoa (or condo) have in reserves
There's no single dollar figure. The honest answer is: enough to be at or near 100% funded against your own component inventory, which is a percentage, not a flat number. "Percent funded" means your current reserve balance divided by the theoretical full amount you'd have if you'd been saving perfectly all along for every component at its current age. A study that comes back at 100% funded means the association's reserves match the ideal savings curve for its specific buildings and equipment. Most real-world associations run lower than that, and the community-association industry treats anything above roughly 70% funded as reasonably healthy, with under 30% considered a serious warning sign (these are common industry benchmarks used by reserve specialists, not a statutory threshold). Florida changed the rules dramatically after the Surfside collapse. As of the 2022 and 2023 amendments to Fla. Stat. 718.112, condo associations with buildings three stories or more must, starting with the fiscal year beginning January 1, 2025 (after a legislative delay in 2024), fund reserves for the SIRS-designated components at 100%, full funding, with no more pooling those items with other reserve categories and no more annual member votes to waive or reduce funding for them [1][2]. "Reserve funds and any interest accruing thereon... may not be used for any purpose other than their intended purpose" is the general statutory rule for how reserve money must be spent once collected [1]. That restriction applies whether or not the association is subject to SIRS. For the general operating reserve items outside the SIRS list (things like pool furniture, landscaping equipment, non-structural items), the board still has more flexibility on funding levels and can, in many cases, use the pooled or cash-flow method and even a member vote to waive or reduce funding, subject to the declaration and current statute. Confirm the current waiver rules with your association's counsel, because this is one of the areas the legislature keeps revisiting.
how much does a reserve study cost
For a Florida condo, a standalone reserve study (not the SIRS engineering inspection) typically runs somewhere in the range of $1,500 to $6,000+ depending on the number of units, number of components, and whether it's a "level 1" full study with on-site inspection versus an update of an existing study. Larger high-rises with more components and structural complexity can run higher. A SIRS specifically, because it requires a licensed engineer or architect and destructive or non-destructive testing on structural elements, typically costs more than a standard reserve study alone, often in the range of a few thousand dollars for a small building up into the tens of thousands for a large, older high-rise, though DBPR and the statute do not publish a fixed price schedule; costs vary by firm, building size, and scope [1]. Get multiple quotes from Florida-licensed engineers or architects, and ask whether the quote bundles the SIRS with the milestone structural inspection, since some firms offer a discount for doing both at once given the overlapping site visit and documentation. Boards should budget the reserve study or SIRS cost itself as an operating line item, not a reserve expense, since it's a professional service fee, not a capital replacement.
how often does a Florida condo need to update its reserve study or SIRS
Florida statute requires the SIRS to be performed at least every 10 years for buildings subject to the requirement, with the first one tied to the building's milestone inspection timeline [1]. A standard (non-SIRS) reserve study doesn't have a fixed statutory update interval the same way, but best practice in the reserve-study industry is to do a full study with a new site visit every 3 to 5 years, and an update (adjusting numbers without a full re-inspection) in the years between. The milestone inspection itself, required under Fla. Stat. 553.899, has to happen by the time a building reaches 30 years of age (or 25 years if it's within three miles of the coast), and then every 10 years after that [3]. That milestone report and the SIRS are related but separate documents: the milestone inspection is a structural safety report from a licensed engineer or architect, while the SIRS is the reserve funding study for structural components, though many firms conduct both inspections in the same site visit to save cost. Boards juggling both deadlines on the same calendar often find that organizing them together, rather than as two separate scrambles, is the difference between a calm transition and a last-minute special assessment fight at the annual meeting.
who has to comply: which buildings need a SIRS
Florida's SIRS requirement applies to condominium associations with at least one building on the condominium property that is three stories or more in height, as determined using the same measurement standard as the milestone inspection statute [1]. Buildings under three stories are exempt from SIRS. Timeshares are excluded by the same statutory provision. DBPR (the Florida Department of Business and Professional Regulation, Division of Condominiums, Timeshares, and Mobile Homes) is the state agency that oversees condo association compliance and publishes guidance and forms related to these requirements [4]. If you're unsure whether your specific building's height, story count, or distance from the coast triggers the requirement, that's a determination for your association's engineer and legal counsel, not something to guess at from a blog post.
are hoa special assessments tax deductible
Generally, no, not for the individual homeowner claiming a personal income tax deduction, and this is one of the most common misconceptions boards run into when explaining a special assessment to owners. The IRS treats regular HOA assessments and most special assessments as a personal, nondeductible expense, the same way your own homeowner's insurance or routine home maintenance isn't deductible, because it's a cost of maintaining your personal residence, not a business or investment expense [5]. There are narrow exceptions. If part of the home is used for a qualifying home office or rental purposes, a portion of the assessment tied to that business-use percentage may be deductible as a business expense, subject to normal home-office or rental-property rules under IRS Publication 587 [6]. And if a special assessment is specifically for a casualty-loss repair in a federally declared disaster area, there can be casualty-loss deduction implications, though the rules are narrow, since the Tax Cuts and Jobs Act limited personal casualty-loss deductions to federally declared disasters starting with the 2018 tax year [7]. This is genuinely a question for a CPA, not a board member or a property manager, and definitely not this article. If you're an owner facing a large special assessment and wondering about the tax angle, get an actual tax professional's read on your specific situation before you file.
reserve study vs. SIRS vs. milestone inspection: what's the difference
| Reserve study (standard) | Funding plan for all major components, condo or HOA | Reserve specialist, sometimes an engineer | Not separately mandated by statute for standard items; SIRS items are | |
|---|---|---|---|---|
| SIRS (Structural Integrity Reserve Study) | Funding plan for specific structural components only (roof, load-bearing walls, floor, foundation, fireproofing, plumbing, electrical, waterproofing) | Licensed engineer or architect | Fla. Stat. 718.112(2)(g) [1] | |
| Milestone inspection | Structural safety and integrity report, pass/fail on visible signs of distress | Licensed engineer or architect | Fla. Stat. 553.899 [3] | A board can, and often should, schedule the SIRS site inspection alongside the milestone inspection, since both need an engineer or architect walking the same building looking at similar structural elements. But they answer different questions: the milestone inspection asks "is this building structurally safe right now," and the SIRS asks "how much money do we need saved for the structural components over the next 20 to 30 years." For a full breakdown of the milestone deadline calendar by building age and coastal distance, boards should check our sister content on milestone timelines, and for the reserve fund relief provisions the legislature passed after initial 2022 sticker shock, see florida condo reserve fund relief. |
These three terms get used interchangeably by frustrated board members, and they shouldn't be, because they're different documents with different purposes, different professionals, and sometimes different deadlines. | Document | What it covers | Who performs it | Statutory basis |
what happens if a board skips or underfunds the required reserve study
Failing to complete a required SIRS or failing to fund the mandated structural reserve line items at 100% starting with the 2025 fiscal year isn't just a bad practice, it exposes the board and the association to real legal and financial risk. Owners can sue, DBPR can investigate complaints against the association, and lenders (including Fannie Mae and Freddie Mac, which both maintain condo project eligibility rules tied to reserve adequacy and milestone/SIRS compliance) can decline to approve mortgages in the building, which tanks resale values association-wide [1][4]. Beyond the legal exposure, the practical result of skipping a reserve study is almost always a special assessment down the road, usually bigger and more painful than if the board had saved gradually. A board that ignores a $900,000 roof replacement for five years doesn't make the roof cheaper; it makes the eventual bill land all at once, right when interest rates or material costs might be at their worst. Boards juggling the SIRS, the milestone inspection, insurance renewal timing, and annual meeting disclosures often lose track of which deadline is next. That's the specific gap a Building-Specific Board Compliance Kit is built to close: a one-time, $199 tool that organizes your building's specific deadlines, generates the owner notices Chapter 718 requires, and keeps the paperwork trail a board needs if an owner or DBPR ever asks for proof of compliance. It doesn't replace the engineer, the reserve specialist, or your attorney; it keeps their work organized and on schedule.
how do you read your own reserve study once you get it back
Start with the percent-funded number on page one, then go straight to the component table and check the remaining useful life column against your own memory of the building. If the study says your roof has 12 years left and you know it was replaced 9 years ago on 20-year materials, something's off, either the inspector missed the install date or the materials aren't performing as expected, and it's worth a follow-up call. Next, check the funding method. Straight-line and component/cash-flow methods produce different annual contribution numbers for the same building, and boards sometimes get quoted a lowball annual figure because the preparer used straight-line averaging across everything rather than funding the near-term items faster. Ask which method was used and why. Finally, look at the inflation assumption baked into future costs. A study that assumes 3% annual construction inflation and one that assumes 5% can produce meaningfully different 20-year funding targets for the same building, and after the material cost spikes of 2021 to 2023, some reserve specialists have pushed their assumptions higher. Ask your preparer to walk you through that number specifically before you present the study to the ownership at the annual meeting. For the raw statutory text every board should keep bookmarked, the current version of the reserve statute is at Fla. Stat. 718.112 on the Florida Senate's official statutes site [1], and DBPR's condominium division page has current forms and guidance [4].
Frequently asked questions
what is a reserve study for a condo association
A reserve study is a report that inventories every major common-element component (roof, paving, elevators, structure), estimates remaining useful life, prices replacement, and sets an annual savings schedule. For Florida condos over three stories, the structural portion is a mandatory SIRS under Fla. Stat. 718.112(2)(g), done by a licensed engineer or architect.
what is a reserve study for an hoa
For an HOA, a reserve study covers shared amenities the association owns, like a clubhouse, pool, private roads, or entry gates, and builds a savings plan for their eventual replacement. Florida's SIRS mandate applies to condominiums under Fla. Stat. 718.112, not HOAs, so an HOA reserve study is generally voluntary unless the declaration requires one.
what is an hoa assessment
An HOA assessment is the recurring fee owners pay to fund the association's operating budget and reserves, usually billed monthly or quarterly. A special assessment is a separate one-time charge levied when an unbudgeted or underfunded cost, like an emergency repair, exceeds what regular assessments and reserves can cover.
how much should an hoa have in reserves
There's no universal dollar figure; the benchmark is percent funded, meaning the current balance divided by the ideal savings-to-date for the building's actual components. Industry practice generally treats above 70% funded as healthy and under 30% as a warning sign. Florida law requires 100% funding of SIRS structural components for qualifying condos starting the 2025 fiscal year.
how much does a reserve study cost
A standard Florida condo reserve study typically runs $1,500 to $6,000 or more depending on unit count and component complexity. A SIRS, which requires a licensed engineer or architect and structural testing, usually costs more, sometimes into the tens of thousands for large or older high-rises. Get multiple licensed-firm quotes; the state doesn't set a fixed price.
are hoa special assessments tax deductible
Generally no. The IRS treats HOA assessments, including special assessments, as a nondeductible personal expense of maintaining your home, similar to routine maintenance. Narrow exceptions exist for a qualifying home office, rental-use portion of the property, or a federally declared disaster casualty loss. Confirm your specific situation with a CPA.
how often does Florida require a SIRS update
Fla. Stat. 718.112(2)(g) requires the Structural Integrity Reserve Study to be performed at least every 10 years for qualifying condo buildings, tied to the same cycle as the milestone structural inspection. Standard (non-SIRS) reserve studies don't have a fixed statutory interval, but industry practice recommends a full update every 3 to 5 years.
what buildings need a SIRS in Florida
Condominium associations with at least one building three stories or more in height must complete a SIRS under Fla. Stat. 718.112. Buildings under three stories and timeshares are excluded. If you're unsure how your building's height or story count is measured, confirm with your engineer and association counsel.
what's the difference between a reserve study and a milestone inspection
A milestone inspection, required by Fla. Stat. 553.899, is a structural safety report answering whether the building shows signs of distress; it's due at 30 years (25 if within three miles of the coast) and every 10 years after. A SIRS is a funding study answering how much money should be saved for structural components. They're often scheduled together but serve different purposes.
can a Florida condo association still waive reserve funding
For the SIRS-designated structural components, no. As of the fiscal year beginning January 1, 2025, associations subject to SIRS must fund those items at 100% with no member vote to waive or reduce them. For non-SIRS reserve items, boards may still have more flexibility to pool funds or hold a waiver vote, subject to the declaration; confirm current rules with counsel since this area has changed multiple times.
who performs a reserve study or SIRS in Florida
A standard reserve study is typically done by a qualified reserve specialist, sometimes an engineer. A SIRS specifically requires the inspection portion to be performed by a Florida-licensed engineer or architect under Fla. Stat. 718.112(2)(g). DBPR oversees condo association compliance and complaint investigation statewide.
what happens if a board doesn't get a required reserve study or SIRS done
The association risks legal exposure, owner lawsuits, and DBPR complaint investigations. Lenders including Fannie Mae and Freddie Mac tie mortgage approvals in a building to milestone and reserve compliance, so noncompliance can freeze buyers out of financing and depress resale values association-wide. It also almost always leads to a larger, more sudden special assessment later.
does a reserve study include a cost estimate for every repair
Yes, that's the core of it: every major component listed gets a current-dollar replacement or major-repair cost estimate, usually with a stated inflation assumption for future years. The study then compares those projected costs against your projected reserve balance year by year for 20 to 30 years to show whether you're on track.
