TL;DR
Florida condo associations (3+ stories) must fund reserves for roof, structure, plumbing, electrical, waterproofing, and other items identified in a structural integrity reserve study (SIRS), with no more waiving or underfunding those specific line items starting with fiscal year 2025 budgets. Most boards need a reserve study costing $2,000 to $20,000+ and should start planning at least a year before the deadline hits.
What is a reserve study?
A reserve study is a professional assessment of a building's major shared components (roof, elevators, pool, structure, plumbing, paving, and similar big-ticket items) that estimates how much life each component has left and how much it will cost to repair or replace. Think of it as a long-range capital plan for the building, done by someone who actually inspects the property rather than guessing. A standard reserve study has two parts: the physical analysis (what's out there, what condition it's in, how many years until it needs work) and the financial analysis (how much money the association should be setting aside each year to pay for that work without a surprise bill). Good studies get updated every few years because materials age, costs shift, and a hurricane or a leak can change the timeline overnight. In Florida, for buildings three stories and higher, the law now requires a specific flavor of this called a structural integrity reserve study, or SIRS, and it has to be performed by a licensed engineer or architect [1]. That's different from a generic financial reserve study a management company might run internally. The statute spells out which components a SIRS has to cover: roof, structure (load-bearing walls and other primary structural members), fireproofing and fire protection systems, plumbing, electrical, waterproofing and exterior painting, windows and exterior doors, and "any other item that has a deferred maintenance expense or replacement cost that exceeds $10,000 and the failure to replace or maintain such item negatively affects the items listed" [1]. If you want the mechanics of ordering one, timing it around your milestone inspection, and picking an engineer, the reserve study guide walks through that step by step.
What is a reserve study for an HOA?
For a homeowners association (single-family homes, townhomes, or low-rise communities governed by Chapter 720 rather than Chapter 718), a reserve study serves the same basic purpose but the legal requirement is lighter. HOAs generally are not required to complete a SIRS the way condos are; that mandate is specific to condominium associations under Florida Statutes Chapter 718 [2]. That doesn't mean an HOA reserve study is optional in every sense. Many HOA governing documents (the declaration or bylaws) require the board to maintain reserves and to base contributions on some kind of study or estimate. And plenty of well-run HOAs commission a study voluntarily because underfunded reserves are the single most common reason for a large, unpopular special assessment later. If your community has shared amenities like a clubhouse roof, a private road, gates, or a pool, a study is cheap insurance against getting blindsided. The hoa reserve study page covers the differences in more detail, including which HOAs get pulled into stricter rules because they include a building three stories or taller.
What is an HOA assessment (and what is a condo assessment)?
An assessment is simply the money a board charges owners to pay for the association's expenses. There are two basic kinds. Regular (or annual) assessments are the recurring dues that cover operating costs and reserve contributions, usually billed monthly or quarterly. Special assessments are one-time charges for something the regular budget didn't cover, often a big repair, a legal settlement, or a reserve shortfall that just got discovered. Florida law gives associations fairly broad authority to levy both types, but the process matters. Chapter 718 requires condo boards to adopt an annual budget that includes reserve line items unless the members voted to waive or reduce them (and remember, for the SIRS-covered components, that waiver option is now gone for many buildings) [1]. Special assessments typically require a board vote at a properly noticed meeting, and depending on your bylaws, sometimes a membership vote too. Owners often ask what is a reserve study for hoa versus what is hoa assessment because the two get confused. The study is the planning document. The assessment is the bill. A good reserve study is what should be driving the size of your regular assessment increases, so you're not stuck explaining a five-figure special assessment out of nowhere. For a plain breakdown of how special assessments get approved and billed, see hoa special assessment.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure that applies to every building, and anyone who gives you one number without knowing your building's age, roof type, and component list is guessing. The honest answer is: enough to cover the fully funded reserve amount calculated in your study for each required component, spread across the years remaining on that component's useful life. For Florida condos three stories and up, the target isn't optional anymore for SIRS components. Starting with the budget adopted for the 2025 fiscal year, boards must fund reserves for roof, load-bearing structural elements, fireproofing, plumbing, electrical, waterproofing, and windows/doors at the level the SIRS calculates, without the ability to vote to waive or underfund those specific items [1] [1]. Non-SIRS reserve items (things like painting the clubhouse or resurfacing a tennis court) can still be waived or reduced by a member vote in many associations, subject to your documents. A common industry rule of thumb, used by reserve specialists outside Florida too, is that a well-funded association should be somewhere around 70% funded relative to its fully funded balance, with anything under 30% considered a red flag for looming special assessments. That threshold comes from reserve-planning practice rather than Florida statute, so treat it as a sanity check, not a legal requirement. What the statute actually requires is that the board's contribution matches the SIRS schedule for covered items, full stop. If you're trying to reverse-engineer a rough number before your SIRS comes back, a common back-of-envelope estimate used by reserve professionals is that annual reserve contributions for aging coastal buildings often land somewhere between 10% and 40% of the total operating and reserve budget, depending heavily on roof age and how much deferred maintenance already exists. That range is wide on purpose. Buildings with a 40-year-old roof and corroded rebar need vastly more than a 10-year-old building with a fresh roof.
How much does a reserve study cost?
Reserve study pricing depends on building size, number of components, and whether you're paying for a basic financial-only study or a full SIRS with physical inspection by a licensed engineer or architect. As a general range seen across Florida associations, expect roughly $2,000 to $6,000 for a smaller condo (say, under 50 units) doing a basic reserve study, and anywhere from $8,000 to $20,000 or more for a larger or older building needing a full SIRS with structural inspection, especially if it's also coordinated with a milestone inspection. Those figures aren't set by statute; they come from what engineering and reserve-study firms typically quote, and they vary by region, building complexity, and how much documentation (permits, prior inspection reports, as-built drawings) already exists. A building with clean records and recent inspections usually pays less than one where the engineer has to reconstruct history from scratch. DBPR, Florida's Department of Business and Professional Regulation, oversees condominium and cooperative associations and publishes guidance and forms related to these requirements, though it does not set or cap reserve study fees. Get at least two quotes, ask specifically whether the quote includes a full physical inspection of every required SIRS component or just a desk review, and confirm the firm's engineer or architect is properly licensed in Florida. For a side-by-side on what a full study typically includes line by line, the reserve study for condo association page has a breakdown.
What deadlines actually apply, and to which buildings?
| Milestone structural inspection | Condos/co-ops 3+ stories | 30 years from certificate of occupancy (25 years if within 3 miles of a coastline), then every 10 years [3] | |
|---|---|---|---|
| Structural Integrity Reserve Study (SIRS) | Condos/co-ops 3+ stories | Completed by Dec 31, 2024; updated at least every 10 years [1] | |
| Fully funded reserves for SIRS components | Same buildings, based on SIRS results | Budgets adopted for fiscal year 2025 and beyond [1] [1] | Boards sometimes discover in year one of ownership on a board that they're already behind on more than one of these at once. If your building sits near the coast, confirm the exact mileage measurement with your local building official, because the 25-year trigger versus the 30-year trigger changes your entire timeline. The florida condo reserve fund relief page covers the narrow relief options the legislature has floated for associations that can show hardship, though those options have been limited and shouldn't be counted on as a substitute for planning. |

Are HOA and condo special assessments tax deductible?
For most individual condo or HOA owners using the property as a primary residence or personal second home, special assessments are generally not tax deductible. The IRS treats them like a capital improvement to your property (similar to putting a new roof on a single-family house you own outright): it may add to your cost basis, which can reduce capital gains tax when you sell, but it isn't an itemized deduction in the year you pay it [4]. There are exceptions. If you rent the unit out, a portion of a special assessment tied to repairs (versus improvements) may be deductible as a rental expense in the year it's paid, or depreciated over time if it's a capital improvement. The line between a deductible repair and a capitalized improvement is genuinely fuzzy in tax law, and it depends on facts the IRS looks at case by case. This is a tax question, not a Florida condo law question, and the honest answer is: don't guess, and don't take a board member's word for it. Ask a CPA who handles rental or real estate clients. The Florida statutes we're citing here have nothing to say about IRS treatment, and no one on your board is qualified to give you a tax opinion, however confident they sound at the annual meeting.
How do reserve requirements differ for older versus newer buildings?
Age changes almost everything about a Florida condo's reserve math, starting with when the milestone inspection clock even starts. A building that got its certificate of occupancy in 1985 and sits half a mile from the beach hit its 25-year milestone deadline back in 2010 and should now be on something like its third 10-year inspection cycle. A brand-new tower that got its CO in 2023 doesn't face a milestone inspection until roughly 2048 (30 years out, assuming it's not within 3 miles of the coast) [3]. But newer buildings still need a SIRS and still need to be funding reserves for those same categories from day one, just with longer runway on component life. Older buildings, especially those built before more modern building codes and corrosion-resistant materials became standard, tend to get much rougher numbers back from their SIRS engineer on structural and waterproofing components. That's exactly the population the legislature was targeting after the 2021 Surfside collapse prompted the current wave of statutory changes [1] [3]. If your building predates 1990 and sits near saltwater, budget more time and more contingency in your reserve estimates, because rebar corrosion and concrete spalling findings are common and expensive once an engineer gets up close.
What happens if a board doesn't fund reserves properly?
Short term, nothing dramatic happens automatically; there's no reserve police showing up the day after a missed contribution. Longer term, underfunded reserves show up as one of two bad outcomes: a large special assessment that hits owners all at once, or deferred maintenance that turns a $50,000 repair into a $500,000 one because you waited. Under current law, for the SIRS-covered components in qualifying buildings, boards no longer have the legal option to vote to waive or reduce those specific reserve contributions the way they could for other line items [1] [1]. That's a meaningful change from the old rules, where members could vote every year to underfund reserves and kick the can down the road. Boards that try to skip this now are exposing themselves to real liability, on top of the practical problem that the money still has to come from somewhere eventually. Boards should also know that lenders are watching this closely. Fannie Mae and Freddie Mac have both tightened condo project review standards, asking for documentation on reserve funding, SIRS status, and deferred maintenance before they'll back mortgages in a building. An underfunded association can end up with units that are hard to sell or refinance, which is its own kind of financial damage separate from the special assessment itself.
How should a board actually budget for a SIRS deadline or special assessment?
Start by getting the SIRS done, or updated, well before you need the numbers for budgeting. Waiting until the deadline month to hire an engineer means you're competing with every other board in the state doing the same thing, and pricing goes up when demand spikes. Once you have real numbers, build a multi-year funding plan rather than trying to absorb everything in one year's budget. If the SIRS shows the roof needs full replacement in year 4 and the plumbing needs major work in year 7, spread contributions so both are funded on time rather than treating this as one giant number due immediately. Many boards find that a mix of increased reserve contributions plus a modest, planned special assessment (announced well ahead of time, not sprung on owners) is more palatable than either extreme alone. Document everything. Minutes showing the board reviewed the SIRS, discussed funding options, and voted on a specific plan protect the board if an owner later challenges the assessment. This is also where a lot of boards find themselves buried in paperwork: tracking which components are covered, when the last engineer visit happened, what the milestone inspection deadline is, and what's actually been sent to owners. That kind of organizing and scheduling work is exactly what our $199 Building-Specific Board Compliance Kit is built for at /board-kit-builder; it doesn't replace your engineer or your attorney, it keeps the deadlines, documents, and communications in one place so nothing slips. Before any assessment goes out, check your master insurance policy and any dedicated coverage. If a special assessment is triggered by storm damage rather than routine deferred maintenance, insurance may cover part of the gap, and it's worth reading condo special assessment insurance before assuming owners have to cover 100% out of pocket.
Where should a board start if it's behind on all of this?
If you're a new board member reading this because your building is already past a deadline, don't panic and don't try to fix everything in one meeting. Get the milestone inspection status and SIRS status confirmed first, in writing, from whoever your management company or prior board dealt with. You need to know exactly where you stand before you can plan a budget. Then get quotes for whatever's missing. If you don't have a current SIRS, get quotes from at least two licensed engineering firms. If your milestone inspection is overdue, contact your local building official directly, because the process and any penalties for missed deadlines are administered at the county or municipal level, not by the state [3]. Finally, talk to your association's counsel before you announce anything to owners. Every building's declaration and bylaws have their own quirks about notice requirements, voting thresholds for special assessments, and reserve waiver mechanics that predate the 2024 changes. Confirm with your association's counsel and county building department how the current statute interacts with your specific documents; this article explains the general statewide framework, not your building's legal posture.
Frequently asked questions
What is a reserve study?
A reserve study is a professional evaluation of a building's major shared components (roof, structure, plumbing, elevators, and similar items) that estimates remaining useful life and future repair costs, then calculates how much an association should be saving each year. In Florida, condos 3+ stories need a specific version called a structural integrity reserve study (SIRS), done by a licensed engineer or architect.
What is a reserve study for an HOA?
For a homeowners association, a reserve study serves the same planning function as a condo's, but Florida's SIRS mandate under Chapter 718 generally applies to condominiums, not standard HOAs. Many HOA declarations still require reserve planning, and boards commonly commission a study voluntarily to avoid unexpected special assessments for shared roads, pools, or clubhouses.
What is an HOA assessment?
An HOA assessment is a charge the association levies on owners to cover expenses. Regular assessments fund ongoing operating costs and reserves; special assessments are one-time charges for unbudgeted repairs, legal costs, or reserve shortfalls. Florida law requires proper board notice and, depending on your bylaws, sometimes a membership vote before a special assessment takes effect.
How much should an HOA or condo have in reserves?
Enough to match the fully funded target in your reserve study for each component. For Florida condos 3+ stories, SIRS-covered items (roof, structure, plumbing, electrical, waterproofing, windows/doors) must be funded at the study's calculated level starting with the 2025 fiscal year budget, with no waiver option for those specific items.
How much does a reserve study cost?
Basic reserve studies for smaller Florida condos typically run $2,000 to $6,000. A full structural integrity reserve study (SIRS) with a licensed engineer's physical inspection often costs $8,000 to $20,000 or more for larger or older buildings, especially when combined with milestone inspection work.
Are HOA and condo special assessments tax deductible?
Generally no, for a personal residence. The IRS typically treats a special assessment as a capital improvement that adds to your cost basis rather than an immediate deduction. Rental property owners may deduct or depreciate a portion depending on whether the work is a repair or an improvement. Ask a CPA for your specific situation.
What buildings need a SIRS in Florida?
Condominium and cooperative associations with buildings three stories or higher generally need a structural integrity reserve study under Florida Statutes Chapter 718, covering components like roof, load-bearing structure, plumbing, electrical, waterproofing, and windows/doors, with reports due by December 31, 2024 and updates at least every 10 years.
Can a condo board still waive reserve funding in Florida?
For components covered by the SIRS (roof, structure, fireproofing, plumbing, electrical, waterproofing, windows/doors), no, boards generally can no longer waive or reduce those specific reserve contributions starting with the fiscal year 2025 budget. Non-SIRS reserve items may still be waivable by member vote depending on the association's documents; confirm with counsel.
What's the difference between a milestone inspection and a SIRS?
A milestone inspection is a structural safety check by a licensed engineer or architect, required at 25 or 30 years depending on coastal proximity, then every 10 years. A SIRS is a financial and physical study that sets reserve funding levels for major components. They're related but separate requirements, sometimes done by the same firm around the same time.
Who pays for a reserve study or SIRS, the board or the owners?
The association pays, and that money ultimately comes from owner assessments (regular dues or, if reserves are insufficient, a special assessment). There's no separate government or third-party funding source; the study is treated as an operating or capital expense of the association, budgeted like any other line item.
Does DBPR regulate reserve study companies in Florida?
DBPR (Florida's Department of Business and Professional Regulation) oversees condominium associations broadly and publishes related guidance and forms, but the engineers and architects who perform SIRS work are licensed separately through Florida's Department of Business and Professional Regulation professional licensing boards and Florida Board of Professional Engineers, not as 'reserve study companies' specifically.
What happens if my condo association misses the SIRS or reserve funding deadline?
There's no single automatic statewide penalty triggered the day after a missed deadline, but the board loses the option to waive reserve funding for SIRS components, exposes itself to potential liability, and risks lender and title issues since Fannie Mae and Freddie Mac now scrutinize SIRS and reserve status before backing mortgages in a building.
How often does a reserve study need to be updated?
Florida's SIRS requirement calls for updates at least every 10 years, though many reserve professionals recommend a fresh visual update every 3 to 5 years since material costs, storm damage, and component conditions change faster than a decade in coastal Florida environments.
