TL;DR
Florida law (Ch. 718) now requires condo associations 3+ stories to get a Structural Integrity Reserve Study and fund reserves for the items it covers at full strength, no more waiving or underfunding those specific components. HOAs face lighter reserve rules under Ch. 720. A reserve study typically costs $3,000 to $20,000+ depending on building size and complexity.
What is a reserve study?
A reserve study is a physical inspection and financial analysis that tells an association what its major shared components are, how much life is left in each one, and how much money needs to be set aside now so the association isn't blindsided by a $2 million roof replacement in year 22. A proper reserve study has two parts. The physical analysis catalogs the components (roof, paving, painting, elevators, structural elements, plumbing risers, and for condos now specifically load-bearing walls, primary structural members, waterproofing, and similar building safety items) and estimates remaining useful life for each. The financial analysis then models a funding plan, usually a 20 to 30 year projection, that shows what the reserve balance should look like year over year and what contribution the association needs to collect to get there. For Florida condos in buildings three stories or higher, the physical component piece now has a specific legal name and a specific required author: the Structural Integrity Reserve Study, or SIRS, defined and required under Florida Statutes section 718.112(2)(g) [1]. That study has to be performed by a licensed engineer or architect, more than any reserve study firm. For everything outside the SIRS-covered items, and for most HOAs, a broader reserve study can be done by a reserve specialist, engineer, or qualified reserve analyst, though Florida law doesn't mandate a specific credential outside the condo SIRS requirement. If you want the mechanics of how a study gets built line by line, see our reserve study guide.
What is a reserve study for an HOA?
For a homeowners association (governed by Chapter 720, not Chapter 718), a reserve study works the same way conceptually but the legal requirements are lighter. HOAs are not subject to the SIRS mandate; that's a condominium-specific law. Under section 720.303(6), Florida Statutes, an HOA's reserves (if the association has any funded reserve line items) are member-controlled unless the governing documents say otherwise: owners can vote to waive or reduce reserve funding annually, and many HOA boards do exactly that when a big-ticket capital item isn't imminent [1]. That's legal, but it's also how associations end up doing a $40,000 special assessment on a $12,000 problem, because nobody set aside money for a decade. A reserve study for an HOA usually covers roads, drainage, clubhouse and pool structures, roofing on common buildings, fencing, and irrigation or lighting systems, whatever the association owns and maintains in common. If your HOA has a gate, a private road, or a pool house, get a study. It costs far less than a surprise assessment. See our dedicated hoa reserve study breakdown for what a typical HOA-scale study includes and runs.
How much should an HOA have in reserves?
There's no statutory percentage or dollar floor for Florida HOAs the way there now is for condo SIRS items. The honest answer is: enough to cover the full replacement cost of every major common component by the time it wears out, spread evenly across its remaining life, so no single year requires a special assessment. Most reserve specialists use one of two funding models. The "full funding" model targets 100% of the calculated reserve requirement at all times. The "baseline" or "threshold" model keeps a lower cushion, say enough to handle the next major expense plus a buffer, and accepts more special-assessment risk in exchange for lower monthly dues. Neither is mandated for HOAs by state law; it's a board and membership decision. A rough industry rule of thumb some reserve professionals cite is that reserves funded below roughly 70% of the full-funding target start showing a meaningfully higher chance of a special assessment within five years, though this is professional practice guidance, not a codified Florida standard, and funding adequacy really depends on component age and how soon big items come due. If your HOA hasn't had a study in the last 3 to 5 years, or has never had one, that's the first gap to close before arguing about a target percentage.
How much should a condo have in reserves under Florida's SIRS law?
This is where Florida law got specific in the wake of Surfside. For condo buildings three stories or taller, effective for reserve funding starting with the fiscal year beginning January 1, 2025 (after transitional provisions tied to the December 31, 2024 SIRS completion deadline), associations must fund reserves for SIRS-covered components at 100% of the amount the study calculates, and the membership can no longer vote to waive or reduce that funding for those specific items [1]. That's a real change. Before this law, unit owners at an annual meeting could vote to waive reserves entirely or fund them at whatever level they wanted. Under the current version of section 718.112(2)(f), that waiver option is gone specifically for the structural and building-safety components identified in the SIRS: roof, load-bearing walls and other primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, windows and doors, and any other item with a deferred maintenance expense or replacement cost exceeding $10,000 that would affect habitability [1]. Reserves for non-SIRS items (landscaping, pools, amenity centers not tied to structural safety) can still be adjusted by board or member vote depending on your governing documents, but confirm that distinction with your association's counsel, because how a given item gets classified is a legal reading of the study and the statute, not something a board should guess at. The practical number varies enormously by building. A 3-story, 40-unit building with a newer roof might need modest annual contributions. A 15-story oceanfront tower with aging concrete and a 40-year-old parking structure could be looking at reserve contributions in the hundreds of thousands to millions of dollars a year. There is no single statewide dollar target; it's whatever your engineer's SIRS calculates as the straight-line or component-based funding need.
What is an HOA assessment (and what is a special assessment)?
An HOA assessment, in the plain sense, is just the regular fee owners pay, monthly or quarterly, that funds operating expenses and reserves. It's set in the budget and authorized by the governing documents, typically without a membership vote required for normal increases within stated limits. A special assessment is different: it's an extra, usually one-time charge levied outside the regular budget to cover something the reserves didn't cover, an emergency repair, a insurance shortfall, or a large capital project that came due faster than expected. For condos, the board's authority to levy special assessments and the required notice procedures are set out in section 718.112, and for HOAs in section 720.303 [1] [1]. Special assessments are exactly what a fully funded reserve is supposed to prevent, or at least shrink. A board that funds reserves properly for 15 years might still need a modest special assessment for an unexpected event (hurricane damage beyond insurance, a burst main). A board that's been waiving reserves for 15 years and then faces a mandatory SIRS-funded roof replacement is going to hit owners with a number that changes people's retirement plans. For a full walkthrough of notice requirements, payment plan options, and what boards can and can't do when levying one, see hoa special assessment.
How much does a reserve study cost?
| Basic reserve study (financial-only, no site engineer visit) | Small HOA, under 50 units | $1,500 to $4,000 | |
|---|---|---|---|
| Full reserve study with site visit | Mid-size condo, 50 to 150 units | $3,000 to $8,000 | |
| Structural Integrity Reserve Study (SIRS) by licensed engineer/architect | 3-10 story condo | $8,000 to $20,000 | |
| SIRS, large or high-rise building | 10+ stories, complex structure | $20,000 to $50,000+ | These are market-observed ranges, not statutory figures. The statute itself doesn't set a price; it sets who can perform the study (a licensed engineer or architect for the SIRS) and what it has to cover [1]. Florida's Division of Florida Condominiums, Timeshares, and Mobile Homes publishes SIRS and milestone inspection guidance for associations trying to confirm scope before signing a contract with a firm [2]. Worth noting: a milestone inspection and a SIRS are two different, separately billed things, even though both often get scoped by the same engineering firm at the same time to save on mobilization costs. Don't assume one report satisfies both requirements; check the scope letter. |
Cost depends heavily on building size, number of components, and whether it's a full SIRS-level structural study by an engineer or a broader financial-only reserve study. General market ranges reported by reserve study firms and condo associations across Florida run roughly as follows, though exact pricing varies by market, firm, and building complexity, and boards should get at least two or three quotes: | Study type | Typical building size | Rough cost range |
Are HOA and condo special assessments tax deductible?
For most owners, no. Special assessments paid to a homeowners association or condo association are generally treated as a nondeductible personal expense, similar to regular HOA dues, because the IRS treats them as payments for maintaining your property rather than as taxes or casualty losses [3]. There are narrow exceptions. If the assessment is specifically for a capital improvement to your unit or to common elements that increases the property's basis (rather than routine repair or maintenance), it may be added to your cost basis and reduce capital gains when you sell, rather than being deducted currently. If you rent the unit out, the portion of assessments related to the rental activity may be deductible as a rental expense on Schedule E. And after certain federally declared disasters, casualty-related special assessments tied to storm damage may have different treatment under casualty loss rules. None of this is tax advice specific to your situation. IRS Publication 527 on residential rental property is the right starting reference for the rental-use exception, but any owner facing a large special assessment after a hurricane or a SIRS-driven capital project should talk to a CPA before assuming either way [3].
What are HOA assessments used for, and what's the difference between operating and reserve funds?
Assessments fund two separate buckets that boards are legally required to keep segregated: the operating fund and the reserve fund. The operating fund pays for the stuff that happens every year: landscaping, insurance premiums, management fees, utilities, pool maintenance, routine repairs. The reserve fund is money set aside for big, infrequent, expensive replacements: roofs, paving, painting cycles, elevators, and for condos now, the specific SIRS structural components. Florida law requires condo associations to keep reserve funds separate from operating funds and prohibits commingling except for short-term investment purposes under specific conditions [1]. A board that pulls from reserves to cover an operating shortfall (a common temptation when insurance premiums spike) is creating a problem that compounds. It's more than borrowing from Peter to pay Paul; it's borrowing from a fund that has a legally mandated replenishment schedule for SIRS items and reporting requirements to the state and to owners.
What happens if an association doesn't fund reserves properly?
Two things happen, usually at the same time, and neither is good. First, the deferred maintenance doesn't go away; concrete spalling, roof leaks, and failing waterproofing get worse and more expensive to fix the longer they're ignored. Second, when the money finally has to be raised, it comes as a special assessment, all at once, instead of smoothed across years of manageable dues increases. For condos, there's now a compliance layer too. Failing to complete a required SIRS by the December 31, 2024 deadline, or failing to fund SIRS-identified reserves at the mandated level once the study is done, creates exposure under Chapter 718 that can affect the association's ability to certify compliance, and can expose board members to claims that they breached their fiduciary duty if losses result [1] [1]. Boards juggling a SIRS report, a milestone inspection report, updated bylaws language, and a reserve funding schedule all at once often lose track of deadlines simply from volume, not neglect. That's the specific gap our $199 Board Compliance Kit is built to close: it organizes your building's SIRS and milestone deadlines, reserve line items, and required owner notices into one tracked calendar so nothing slips through a board transition or a management company change. It doesn't replace your engineer, your CPA, or your attorney; it keeps their work organized and on schedule.
How do reserve requirements differ for condos versus HOAs in Florida?
| SIRS required | Yes, buildings 3+ stories, completed by Dec 31, 2024 [1] | No | |
|---|---|---|---|
| Who performs the structural study | Licensed engineer or architect | Not mandated | |
| Can owners waive reserve funding | No, for SIRS-covered components, as of current law [1] | Yes, by annual member vote unless docs say otherwise [1] | |
| Reserve fund must stay separate from operating | Yes | Generally yes under governing documents/law, confirm specifics with counsel | |
| Milestone inspection required | Yes, 3+ stories, per s. 553.899, tied to age and coastal proximity | No statewide equivalent | For a condo board, the practical order of operations is: get the milestone inspection done on schedule, get the SIRS done (often by the same engineering firm), then fund reserves at the level the SIRS calculates for those specific components, with no more waiver vote available for that portion. For an HOA board, reserves are more of a governance choice: the law allows flexibility, but flexibility isn't the same as safety. For the milestone side of this timeline specifically, see our milestone inspection guides. For a side-by-side on structural study requirements, see reserve study for condo association. |
This is the single most confused point among board members, because "reserves" gets used loosely to describe two legally distinct regimes. | Requirement | Condo associations (Ch. 718) | HOAs (Ch. 720) |
Does insurance change how much an association needs in reserves?
Yes, indirectly, and a lot of boards miss this connection. If your master policy has a high wind or named-storm deductible (often 2% to 5% of the building's insured value for coastal condos), or if certain structural repairs simply aren't covered, that gap has to come from somewhere: either reserves or a special assessment. Some associations are now carrying supplemental policies specifically to cover special-assessment risk for unit owners, essentially insurance against the association levying a large one-time charge. That's a newer product in the Florida market and coverage terms vary a lot by carrier, so read the policy language carefully before assuming it covers a SIRS-driven assessment. See condo special assessment insurance for how that coverage works and what it typically excludes.
Where the deadlines and rules can still change
Florida's condo safety statutes have been amended multiple times since the 2021 Surfside collapse, including adjustments to the SIRS deadline, funding rules, and milestone inspection timing, most recently through Senate Bill 1742 (2024), which created limited financing and phased-funding relief options for associations facing steep near-term assessment burdens [4]. Some of that relief involves lines of credit or phased catch-up schedules rather than outright waivers. Because the legislature has revisited this area almost every session since 2022, any specific dollar threshold, deadline, or waiver rule in this article should be confirmed against the current version of Chapter 718 on the official Florida Senate statutes site, and against your association's own counsel, before your board makes a funding decision [1]. See florida condo reserve fund relief for the latest on that specific provision, and check it again close to your fiscal year budgeting cycle, because this is not a settled area of law.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment of an association's major shared components (roof, structure, paving, plumbing, and similar systems) that estimates remaining useful life and calculates how much money needs to be saved annually to replace each item without a surprise special assessment. For Florida condos 3+ stories, the structural portion is a legally defined Structural Integrity Reserve Study, or SIRS, under s. 718.112.
What is a reserve study for an HOA?
It's the same concept applied to homeowners association property: roads, drainage, clubhouse structures, pools, fencing, and similar common elements. Florida law doesn't mandate HOA reserve studies or a specific credential the way it does for condo SIRS, but skipping one leaves the board guessing at funding levels, which is how special assessments happen.
What is an HOA assessment?
It's the regular fee (usually monthly or quarterly) owners pay under the governing documents to fund operating costs and reserves. A related but different term, 'special assessment,' refers to a one-time extra charge levied outside the normal budget, usually for an emergency repair or a capital project reserves didn't fully cover.
How much should an HOA have in reserves?
There's no fixed statewide dollar or percentage requirement for Florida HOAs. The safest approach is full funding, meaning reserves track 100% of the calculated replacement cost schedule from a current reserve study. Funding below roughly 70% of that target is generally considered by reserve professionals to carry meaningfully higher special-assessment risk within a few years.
How much should a condo have in reserves in Florida?
For SIRS-covered structural components in buildings 3+ stories, current law requires funding at 100% of the amount the SIRS calculates, with no member waiver allowed for those items. The exact dollar figure is building-specific and comes from the engineer's study, not a statewide table.
How much does a reserve study cost in Florida?
Basic financial-only studies for small HOAs often run $1,500 to $4,000. Full reserve studies with a site visit for mid-size condos run roughly $3,000 to $8,000. A full engineer-performed SIRS for a mid-rise condo commonly runs $8,000 to $20,000, and can exceed $20,000 to $50,000 for large or complex high-rises.
Are HOA or condo special assessments tax deductible?
Generally no, for personal residences. The IRS treats them like regular dues, a nondeductible personal expense, unless the assessment funds a capital improvement (which may adjust your cost basis) or relates to a rental property (which may be deductible as a rental expense). Talk to a CPA for your specific situation.
What is the difference between a milestone inspection and a SIRS?
A milestone inspection is a structural safety inspection of the building required at certain age and height thresholds under s. 553.899, performed by a licensed engineer or architect. A SIRS is a separate reserve-funding study under s. 718.112 that determines how much money must be saved for specific structural and safety components. They're often scoped together but are legally distinct requirements.
Can a Florida condo association still waive reserve funding?
For components identified in a required SIRS (roof, structure, waterproofing, plumbing, electrical, and similar building-safety items), current law removes the member waiver option, requiring full funding instead. Non-SIRS items may still be subject to waiver depending on governing documents; confirm the classification with association counsel.
What happens if a condo association misses the SIRS deadline?
The statewide SIRS completion deadline was December 31, 2024, for applicable condo buildings 3+ stories. Missing it creates compliance exposure under Chapter 718 and can complicate the association's ability to certify compliance to owners and lenders. There's no universal grace period built into the statute; confirm current status with counsel and your local building official.
Do reserve funds have to be kept separate from operating funds?
Yes, for Florida condos under Chapter 718, reserve accounts must be maintained separately from operating accounts, with limited exceptions for short-term investment. Using reserve money to cover operating shortfalls is a common and serious compliance problem that can trigger both statutory issues and fiduciary duty claims against the board.
Who can perform a Structural Integrity Reserve Study in Florida?
A SIRS must be performed by a licensed engineer or architect, per s. 718.112(2)(g). A general reserve study firm without that licensure can prepare the financial funding schedule, but the structural component inspection portion legally requires that professional credential. Verify licensing through Florida's Division of Florida Condominiums, Timeshares, and Mobile Homes before hiring.
Does insurance affect how much an association needs in reserves?
Yes. High named-storm deductibles (often 2% to 5% of insured value) and coverage exclusions on aging structural components mean gaps that reserves or a special assessment must cover. Some associations now buy supplemental coverage aimed at special-assessment risk, though terms vary significantly by carrier.
