TL;DR
Very common, and getting more common in Florida. State surveys and industry reports since the 2022 reserve-funding law (SB 4-D) show a large share of associations facing special assessments tied to milestone inspections, SIRS-driven reserve fully-funding, and insurance cost spikes. There's no single national registry, but the trend line is unmistakable: underfunded reserves plus mandatory structural requirements equal more assessments, not fewer.
How common are special assessments in condos right now?
In Florida, special assessments have gone from an occasional headache to something close to a routine event for older buildings. There's no single federal database that tracks every special assessment nationwide, so anyone who tells you an exact percentage for "all US condos" is guessing. But Florida gives us better visibility than most states because of what happened after the Champlain Towers South collapse in June 2021. That collapse killed 98 people and triggered the Florida Legislature to pass SB 4-D in 2022, which created mandatory Milestone Structural Inspections and Structural Integrity Reserve Studies (SIRS) for condo and cooperative buildings three stories or more [1]. The law phased out an old loophole that let owners vote to waive or reduce reserve funding for certain structural components. Once that waiver option disappeared for SIRS-designated items, thousands of associations discovered their reserves were nowhere close to what full funding actually requires. Community association management companies and law firms that track this statewide have reported that a majority of older, coastal, and previously underfunded associations are now facing either special assessments, loan financing, or steep regular assessment increases, sometimes all three. The Community Associations Institute (CAI), the largest trade and advocacy group for the industry, has published member surveys showing rising percentages of Florida associations reporting a special assessment in the past two to three years, driven overwhelmingly by SIRS compliance and insurance premium increases [2]. If your building is 25 or 30 years old, coastal, or has deferred major repairs, the honest answer is: assume you're more likely than not to face one in the next few years, not less likely.
What is a reserve study, and why does it matter for assessments?
A reserve study is a professional evaluation of a building's major common-element components (roof, structure, elevators, plumbing, paving, pool, etc.) that estimates their remaining useful life and the cost to repair or replace them, then produces a funding plan for how much the association should be setting aside each year. Florida's version for condos three stories and up is called the Structural Integrity Reserve Study, or SIRS, and it specifically covers structural and life-safety components: roof, load-bearing walls, primary structural members, waterproofing, electrical, plumbing, and fireproofing/fire protection systems, among others listed in the statute [1]. The point of a reserve study isn't paperwork for its own sake. It's the tool that tells a board, in dollars, whether the association is collecting enough money now to avoid a five- or six-figure surprise bill later. Without one, boards have historically guessed, low-balled reserve contributions to keep monthly fees politically comfortable, and then gotten hit with a special assessment when the roof or the parking structure actually failed. Florida law now requires SIRS to be based on a visual inspection performed by a licensed engineer or architect [1], and requires associations to have the study completed by December 31, 2024 for buildings that reached their milestone inspection threshold, per Fla. Stat. § 718.112(2)(g) [1]. For a deeper walkthrough of what the study actually covers line by line, see our reserve study guide.
What is a reserve study for an HOA, and how is it different from a condo SIRS?
A reserve study for an HOA covers the same basic idea, funding a plan to replace shared components before they fail, but the legal requirements are different from condos. Florida's SIRS mandate under Fla. Stat. § 718.112 applies specifically to condominium associations in buildings three stories or higher [1]. Homeowners' associations governing single-family homes or townhomes are generally covered under a separate statute, Fla. Stat. ch. 720, which has its own (generally less strict) reserve disclosure rules and doesn't currently carry a SIRS-style structural mandate [3]. That doesn't mean HOA boards can skip the exercise. Plenty of HOAs run pools, clubhouses, private roads, gates, and drainage systems that cost real money to replace, and a voluntary reserve study is still the only reliable way to know if the HOA's reserve fund is anywhere close to adequate. Many HOA governing documents actually require an annual reserve study or reserve schedule review, independent of state law, so check your declaration and bylaws (with counsel, not guesswork) before assuming nothing applies to you. For HOA-specific detail, see hoa reserve study.
What is an HOA assessment (and how is it different from a special assessment)?
An HOA assessment, in plain terms, is any fee the association charges owners to fund its operations and obligations. There are two basic kinds. A regular assessment (sometimes called dues) is the recurring monthly or quarterly charge that funds day-to-day operating expenses and reserve contributions. A special assessment is a one-time (or occasionally installment-based) charge levied outside the regular budget, usually to cover an unexpected repair, a reserve shortfall, a legal judgment, or a mandated project like a SIRS-driven structural repair. Both types of assessments are typically enforceable the same way: unpaid assessments can accrue interest, late fees, and eventually a lien against the unit, and in serious cases the association can foreclose, under Fla. Stat. § 718.116 for condos [4]. That's why boards can't just "decide not to collect" a special assessment once it's properly levied; state law gives associations real collection teeth, and owners who ignore a special assessment notice are taking a real legal risk. Our hoa special assessment article breaks down notice requirements, payment plan options, and what happens if an owner simply can't pay.
How much should an HOA (or condo) have in reserves?
| 70% or higher | Generally healthy; low special assessment risk from routine wear | |
|---|---|---|
| 30% to 70% | Moderate risk; some components likely underfunded | |
| Under 30% | High risk; special assessment or loan often becomes necessary | |
| 0% to negative | Association has likely deferred major repairs; assessment near-certain | For buildings that were previously granted waivers or partial waivers, our florida condo reserve fund relief page covers the current legislative status and what relief (if any) is still on the table. |
The honest answer is: enough to reach 100% funding of the reserve study's projected schedule, but almost nobody actually starts there. Reserve funding is usually expressed as a percentage, comparing what's actually in the reserve account to what the study says should be there given each component's age and remaining life. Associations at 70% funded or higher are generally considered in reasonably good shape; anything under 30% is considered a serious warning sign by most reserve specialists and by CAI's own educational materials [2]. For Florida condominiums subject to SIRS, the law is now more specific than "aim for a good percentage." Fla. Stat. § 718.112(2)(f) requires associations to fund reserves for SIRS-covered components at the full amount the study recommends, with the old owner-vote waiver no longer available for those specific structural items starting with the 2025 budget year [1]. Non-SIRS components (things like landscaping or a clubhouse) can still potentially be underfunded or waived in some cases, again depending on your specific declaration and the vote requirements involved. Confirm the mechanics with your association's counsel, because the rules on waivers, catch-up funding, and phase-in have shifted more than once since 2022. Here's a rough framing many reserve professionals use, though it's a guideline, not a legal standard. | Reserve funding level | General interpretation |
What triggers a special assessment most often in Florida condos?
Four things show up over and over in reported cases: milestone inspection repair findings, SIRS-driven reserve catch-up, insurance premium and deductible increases, and deferred maintenance finally catching up with the building. Milestone inspections, required under Fla. Stat. § 553.899 for condo and co-op buildings three stories or more once they hit 30 years old (or 25 years old if within three miles of the coast), and every 10 years after, are performed by a licensed engineer or architect [5]. When that inspection turns up "substantial structural deterioration," the association is required to complete Phase 2 inspection and repairs on a timeline set by the local building official, and those repairs are frequently the single biggest line item that forces a special assessment. Insurance is the other major driver that doesn't get enough attention. Florida property insurance premiums for condo associations have risen sharply since 2021, and in some cases associations have seen renewal premiums double or carriers decline to renew at all, forcing associations into surplus-lines coverage at a much higher cost. When the insurance line in the operating budget balloons, boards often have no choice but to special-assess just to keep coverage in place, separate from any physical repair need. If your board is weighing whether property coverage itself needs restructuring, see condo special assessment insurance.
How much does a reserve study cost?
Reserve study costs vary a lot by building size, number of components, and whether it's a full study (with on-site component inspection) or an update. For Florida SIRS specifically, because the law requires a licensed engineer or architect and a visual inspection of structural components under Fla. Stat. § 718.112(2)(g) [1], costs tend to run higher than a generic reserve study that a non-licensed reserve specialist might have historically prepared. Industry pricing reported by Florida engineering firms and community association attorneys generally falls in a range of roughly $3,000 to $20,000+ depending on building size and complexity, with larger high-rises or buildings with unusual structural conditions running higher. There's no statewide fee schedule and DBPR doesn't publish a price cap, so get at least two or three quotes from licensed engineers or architects before committing, and confirm the firm is actually licensed in Florida through the DBPR license search [6]. A cheap study that misses components or lowballs replacement costs is worse than no study at all, because it gives the board false confidence right up until the real bill shows up. This is one area where paying for quality work up front is genuinely cheaper than the alternative.
Are HOA special assessments tax deductible?
Generally, no, not for a typical owner-occupied residence. The IRS treats HOA assessments, regular or special, as a personal, nondeductible living expense in the same category as your regular HOA dues, similar to how home maintenance and repair costs on a personal residence aren't deductible [7]. There's no special IRS carve-out for "special" versus "regular" assessments; the character of the expense (was it for your personal residence, or an investment/rental property) is what matters. If the unit is a rental or investment property, the analysis changes. Special assessments that fund a capital improvement (like a new roof or structural repair) generally get added to your cost basis in the property rather than deducted immediately, while assessments that fund ordinary repairs and maintenance on a rental property may be deductible as a business expense in the year paid, subject to the usual rental property rules under IRS guidance on rental income and expenses . This is genuinely fact-specific and easy to get wrong, so talk to a CPA who handles rental real estate before you assume either way.
How do special assessments compare to loans, for the same repair project?
Boards facing a big SIRS-driven repair bill generally have three paths: a lump-sum special assessment, an installment special assessment, or a bank loan to the association repaid through slightly higher regular assessments over time. None of them are free money; they're just different ways of allocating who pays what, when. A lump-sum special assessment gets the project funded fastest and avoids interest costs, but it hits owners hardest all at once, and some owners (especially those on fixed incomes) genuinely can't pay $15,000 or $30,000 in 30 to 60 days. An association loan spreads the cost over 5, 10, or sometimes 15 years, which is easier on cash flow for owners, but the association pays real interest on top of the principal, and lenders will scrutinize the association's financials and reserve funding status before approving anything meaningful. Some boards blend the two: a moderate special assessment to cover the down payment or immediate costs, plus a loan for the balance. There's no universally "right" answer here; it depends on the building's total repair cost, the age and income profile of the ownership, and how urgently the repair is needed under the milestone inspection timeline. This is exactly the kind of decision where getting ahead of the deadline (rather than reacting to it in the final months) gives the board far more options and far better loan terms.
What should a board actually do to reduce special assessment risk?
Start the SIRS and milestone inspection process early, not at the statutory deadline. Buildings that wait until the last permitted month to schedule their licensed engineer often find every qualified firm in the region booked out for months, which compresses the timeline for addressing findings and increases the odds of a rushed, larger assessment later. Get a real reserve study, not a rough guess from the property manager, and fund it honestly even if it means raising regular assessments now. Owners generally accept a $50 or $100 monthly increase far better than a surprise $20,000 bill three years later, and board members who kept dues artificially low have increasingly faced pointed questions (and in some cases legal exposure) once SIRS shortfalls became public. Document everything: inspection reports, SIRS findings, board votes on funding levels, and owner notices. Florida's notice and recordkeeping requirements around milestone inspections and reserve studies are specific, and a board that can show it followed the statutory process is in a much stronger position if an owner challenges an assessment later. This is genuinely where organized recordkeeping earns its cost. Our own $199 Board Compliance Kit is built around this exact problem for Florida buildings facing a milestone or SIRS deadline: it organizes the inspection and reserve deadlines specific to your building's age, height, and coastal zone, and helps the board keep the notices and records straight. It doesn't replace your engineer, your reserve specialist, or your attorney; it organizes what they produce so the board isn't scrambling to reconstruct a timeline under pressure.
Where can a board get the most reliable, current numbers?
Start with the statute text itself rather than secondhand summaries, because Florida's condo law has changed multiple times since 2022 and informal explainers go stale fast. Fla. Stat. ch. 718 on flsenate.gov is the authoritative source for SIRS, milestone inspection cross-references, and reserve funding rules [1] [1]. DBPR's Division of Florida Condominiums, Timeshares, and Mobile Homes at myfloridalicense.com publishes licensing lookups and consumer guidance relevant to community association managers and the professionals boards hire [6]. For cost and prevalence data beyond the statute itself, CAI's research and advocacy publications are the most citable industry-level source, though their member survey figures are self-reported and should be read as directional trends rather than a precise national census [2]. Local county building departments are the authority on milestone inspection scheduling and the 25-mile coastal threshold determination for your specific building, so when in doubt about your building's exact deadline, call the county, not a blog. And always confirm any specific number or requirement with your association's counsel before basing a board decision on it; statutes change, and this article reflects the law as of the date below, not necessarily the law on the date you're reading it.
Frequently asked questions
How common are special assessments in condos nationally?
There's no single national database tracking special assessment frequency across all US condos. Florida offers the clearest picture because of post-2022 SIRS and milestone inspection laws, and industry surveys (CAI) show a rising share of Florida associations reporting a special assessment in the past two to three years, driven mainly by structural compliance and insurance cost increases.
What is a reserve study?
A reserve study is a professional assessment of an association's major shared components (roof, structure, plumbing, elevators, paving) that estimates remaining useful life, replacement cost, and a funding plan. Florida condos three stories or taller must complete a Structural Integrity Reserve Study (SIRS) covering specific structural items under Fla. Stat. § 718.112.
What is a reserve study for an HOA?
For an HOA, a reserve study serves the same purpose as a condo reserve study, projecting replacement costs and useful life for shared assets like pools, roads, and clubhouses, but it isn't mandated by the same SIRS statute that applies to condos under Fla. Stat. § 718.112. Many HOA governing documents require one independently.
What is an HOA assessment?
An HOA assessment is any charge the association levies on owners to fund operations, reserves, or repairs. Regular assessments are recurring dues; special assessments are one-time or installment charges levied outside the regular budget, usually for unexpected repairs, reserve shortfalls, or mandated projects like structural repairs.
How much should an HOA have in reserves?
Reserve health is usually measured as a percentage of the reserve study's recommended funding level. Generally, 70% funded or higher is considered healthy, 30-70% is moderate risk, and under 30% is high risk for a near-term special assessment. Florida condos face stricter statutory funding rules for SIRS components under Fla. Stat. § 718.112.
How much does a reserve study cost?
Costs vary widely by building size and scope, but Florida SIRS studies (which require a licensed engineer or architect) commonly range from roughly $3,000 to $20,000 or more for larger or more complex buildings. Get multiple quotes and confirm licensure through DBPR before hiring.
Are HOA special assessments tax deductible?
For a personal residence, no. The IRS treats HOA assessments, regular or special, as a nondeductible personal living expense. For rental or investment properties, the rules differ: assessments for capital improvements typically add to cost basis, while assessments for ordinary repairs may be deductible as a rental expense. Confirm specifics with a CPA.
What triggers a condo special assessment most often in Florida?
The most common triggers are milestone inspection findings that require structural repair, catch-up funding once SIRS reserve waivers end, and rising property insurance premiums or deductibles. Deferred maintenance that finally reaches failure is the underlying cause behind most of these triggers.
Can a Florida condo board waive SIRS reserve funding?
No, not anymore for SIRS-covered structural components. The waiver option that previously let owners vote to reduce or skip reserve funding for these items was phased out; SIRS-designated components must be funded at the level the study recommends starting with the 2025 budget cycle, per Fla. Stat. § 718.112. Confirm current status with counsel, as this has changed more than once.
How is a special assessment different from a regular HOA assessment?
A regular assessment is the recurring monthly or quarterly charge funding normal operations and reserves. A special assessment is a separate, usually one-time charge levied outside the regular budget for an unexpected or large expense, like a mandated structural repair or a reserve shortfall.
What happens if an owner doesn't pay a special assessment?
Unpaid special assessments generally accrue interest and late fees and can result in a lien against the unit under Fla. Stat. § 718.116. In serious, prolonged nonpayment cases, the association can pursue foreclosure. Owners struggling to pay should contact the board about payment plans immediately rather than ignoring notices.
Is a loan better than a special assessment for funding repairs?
It depends on the building and ownership profile. A lump-sum special assessment avoids interest but burdens owners all at once; a loan spreads cost over years but adds interest expense and requires lender approval based on the association's finances. Many boards use a mix of both for large SIRS-driven repairs.
