TL;DR
A Florida structural integrity reserve study (SIRS) is an engineer's inspection of a condo or co-op building's structural components (roof, load-bearing walls, waterproofing, plumbing, electrical, and more) used to set full, non-waivable reserves under Florida Statutes 718.112. Buildings 3+ stories must complete one; costs typically run $75 to several thousand dollars per unit depending on size and complexity.
What is a structural integrity reserve study (SIRS) in Florida?
A structural integrity reserve study is a specific type of reserve study required for most Florida condominiums and cooperatives in buildings three stories or taller. It is not the same as a general reserve study you might see in other states. Florida law spells out exactly which building components a SIRS must cover. Since the 2022 and 2023 legislative fixes, reserves for those components must be fully funded, with no board vote to waive or reduce them [1]. Under Florida Statutes section 718.112(2)(g), a SIRS must be performed "at least every 10 years" by a licensed engineer or architect, and it has to visually inspect and estimate remaining useful life and replacement costs for at least these components: roof, load-bearing walls and other primary structural members and systems, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, windows and exterior doors, and "any additional 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]. The statute's own language matters here because boards sometimes assume a milestone inspection and a SIRS are interchangeable. They are not. A milestone inspection (required under FS 553.899) checks for substantial structural deterioration at year 30 (or 25 near the coast) and every 10 years after. A SIRS is a reserve-funding document, done on its own 10-year clock, focused on what the building needs to save money for. Some engineers combine site visits for both, which can save money, but they answer different legal questions. For the inspection side of this, see our milestone inspection guide.
What is a reserve study?
A reserve study, in the general sense used across the US, is a physical and financial assessment of a property's major shared components (roofs, pavement, pools, elevators, structural elements) that estimates when each one will need replacement and how much it will cost, then compares that against how much money the association has saved. The output is a funding plan: contribute X dollars per year now, or face a special assessment later. Most reserve studies outside Florida are advisory. Boards can generally choose full funding, partial funding, or bare minimum. Florida flipped that for condos and co-ops in buildings 3+ stories. Once the SIRS is done, the reserve line items it identifies must be funded at 100%, and owners can no longer vote to waive or reduce them, per FS 718.112(2)(f) [1]. That is the single biggest thing that separates Florida's SIRS from a generic reserve study. For a broader look at how reserve studies work outside the SIRS-specific rules, see our reserve study overview.
What is a reserve study for an HOA?
Here things split by property type, and this trips up a lot of board members. The SIRS mandate in FS 718.112 applies to condominiums and cooperatives, not to homeowners' associations (single-family and townhome HOAs) in the way most people think. Florida's HOA reserve statute, FS 720.30185 (added in 2023), instead requires HOAs with buildings that would otherwise need a milestone inspection to get a structural inspection and reserve study covering similar structural components, phased in with reporting deadlines through the DBPR [2]. So a "reserve study for an HOA" in Florida increasingly means the same structural-component analysis as a condo SIRS, just under a parallel statute for HOA-owned buildings. If your HOA has a condo-like building (a clubhouse, a parking structure, a multi-story building it insures and maintains), check FS 720.30185 with your association's counsel, because the phase-in dates and thresholds differ from the condo statute. For general HOA reserve mechanics that predate the 2023 changes, our HOA reserve study page walks through the basics. Don't assume your HOA is exempt just because it's not a high-rise condo. The trigger is building height and age, not ownership structure.
Which buildings actually need a SIRS, and when is it due?
Any condominium or cooperative building in Florida that is three stories or higher, regardless of height above that, must have a SIRS completed. There is no coastal-proximity exemption for the SIRS itself (that distinction matters more for milestone inspection timing, where buildings within three miles of the coast start at 25 years instead of 30 under FS 553.899) [3]. The original deadline set by the 2022 special session was December 31, 2024, for existing buildings. The legislature revisited timing more than once after that, and some associations qualified for transitional relief tied to a study already in progress or a signed contract [1][4]. Deadlines and relief provisions have moved more than once since 2022, so confirm the current date with your association's counsel and your county before you plan around any specific deadline. Our page on Florida condo reserve fund relief tracks the legislative changes as they happen. After the first SIRS, the statute requires a new one "at least every 10 years" [1]. Buildings under three stories, and single-family detached HOA homes, are not swept into this specific requirement, though the 2023 HOA statute (FS 720.30185) creates its own separate structural inspection and reserve obligations for qualifying HOA buildings [2].
How much does a reserve study cost in Florida?
| Under 50 units | $3,000-$10,000 total | |
|---|---|---|
| 50-150 units | $8,000-$20,000 total | |
| 150+ units, high-rise/complex | $20,000-$50,000+ total | These ranges reflect market reporting, not a published state fee schedule. Ask your engineer for a written scope tied to the statutory component list before signing. |
Costs vary enormously by building size, number of components, and whether the engineer is doing a fresh SIRS or updating one alongside a milestone inspection. There's no single verified statewide average from a government source, so treat any number you see, including the ones below, as a market range gathered from industry reporting rather than statute. Small associations (under 50 units) commonly report SIRS costs in the $75 to $150 per unit range for the study itself, sometimes with a flat minimum fee of a few thousand dollars regardless of size, since the engineer still has to visit the site, inspect every required component, and write the report. Larger or more complex buildings (high-rises, buildings with parking garages, extensive waterproofing systems, or multiple structures on one parcel) can run into the tens of thousands of dollars total. Some large coastal towers have reported bills well over $25,000 to $50,000 once every component and every building on the property is covered. The honest range to give a board budgeting for this: expect somewhere between $3,000 and $30,000+ for a single mid-size building, with per-unit cost dropping as unit count rises. Get at least two or three quotes from Florida-licensed engineers or architects, because the fee spread between firms for the same building can be wide, and ask exactly which components each quote includes. A quote that looks cheap because it skips the required $10,000-threshold catch-all component review [1] isn't actually cheaper. | Building size | Typical SIRS cost range (industry estimates) |
Who can perform a Florida SIRS, and what does it have to include?
The statute requires the study be performed by a licensed engineer or architect [1]. Florida's Department of Business and Professional Regulation licenses and disciplines engineers and architects and keeps a searchable license lookup that boards can use before signing a contract [5]. At minimum, the SIRS report has to visually inspect the components listed in FS 718.112(2)(g) and, for each one, estimate the remaining useful life and the estimated replacement cost or deferred maintenance cost [1]. The board then has to use those numbers to set reserve line items in the annual budget. This isn't a document you file and forget. It directly drives what owners pay every year. One practical note board members often miss: the study doesn't have to recommend replacing anything immediately. Its job is to estimate when each component will need work and how much money should already be sitting in reserves for that day. A roof with 12 years of remaining life still needs a reserve line funding its eventual replacement, starting now.
What is an HOA assessment (and how is it different from a special assessment)?
An HOA assessment, in plain terms, is the regular fee owners pay to the association to cover budgeted operating costs and reserve contributions. It's the recurring bill, usually monthly or quarterly, that funds landscaping, insurance, management, utilities for common areas, and reserves. A special assessment is different. It's a one-time (or limited-duration) extra charge the board levies when the regular assessment and existing reserves aren't enough to cover a specific cost, like an emergency roof replacement, a big insurance premium jump, or a structural repair flagged by a SIRS or milestone inspection. Florida condo boards get authority to levy special assessments under FS 718.116 and related budget provisions in FS 718.112, generally without needing a membership vote unless the governing documents say otherwise; confirm the specific vote threshold with your association's counsel, since bylaws vary. See our HOA special assessment explainer for the mechanics, and condo special assessment insurance if you're weighing whether insurance can offset part of the bill. SIRS and milestone inspection findings are two of the most common triggers for special assessments in Florida right now, because the new full-funding reserve rule means boards can no longer quietly underfund a roof or plumbing line item for years and then get surprised.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure or percentage that's "correct" for every association, because it depends entirely on the age, size, and component list of your specific buildings. What Florida law now requires, for condos and co-ops covered by the SIRS mandate, is full funding: the amount that a straight-line or component-based calculation says you need, based on each item's remaining useful life and replacement cost, per FS 718.112(2)(f)-(g) [1]. A rough industry rule of thumb some reserve professionals use outside the statutory minimum is that a healthy reserve fund sits somewhere around 70% or more funded relative to the ideal (component-based) funding level, though this comes from national reserve-study industry practice, not a Florida statute, and Florida's law for SIRS-covered buildings effectively pushes toward 100% funding for the listed structural components specifically. Non-structural reserve items (paint, pool furniture, landscaping equipment) aren't swept into the mandatory full-funding rule the same way, so boards still have some discretion there. The practical answer for a board asking "how much should we have saved": get the SIRS done, get the component-by-component numbers, and fund every structural line item at 100% of what the study calculates. Guessing at a round number like "three months of operating budget" doesn't meet the legal standard anymore for the components the statute covers.
Are HOA and condo special assessments tax deductible?
Generally, no, not for a typical owner-occupied unit. Special assessments for capital improvements or major repairs (a new roof, structural repairs, SIRS-driven work) are usually treated like a capital expenditure. Under IRS Publication 523, amounts you pay for improvements that add to the value of your home, prolong its useful life, or adapt it to new uses generally get added to your cost basis rather than deducted in the year paid [6]. There are narrower exceptions. If you rent out the unit as a rental property, a portion of the special assessment tied to repairs (as opposed to capital improvement) may be deductible as a business expense in the year paid, and depreciation rules can apply to capital items. If part of the assessment covers something like a casualty-loss repair after a federally declared disaster, different rules may apply. None of this is a substitute for actual tax advice. Every owner's situation (primary residence, rental, mixed use) changes the answer, so a CPA familiar with real estate and the current IRS rules should confirm before anyone files a return assuming a deduction [6].
How does a SIRS connect to a milestone inspection, and does a board need both?
Yes, in most cases a condo board covered by the milestone inspection law also needs a SIRS, because the two statutes cover overlapping but legally distinct requirements. Milestone inspections (FS 553.899) exist to catch substantial structural deterioration before it becomes dangerous; SIRS (FS 718.112) exists to make sure money is set aside to actually fix things over time [3][1]. A board can sometimes hire the same engineering firm to handle both, and some firms structure their proposals that way to reduce duplicate site visits and inspection costs. But the reports serve different purposes and go through different filing and disclosure requirements, so don't assume one satisfies the other. Read the actual engineer's engagement letter to confirm scope before assuming coverage. Boards juggling both deadlines at once (a milestone report due at year 25 or 30, and a SIRS due on its own 10-year clock) often find the scheduling and document tracking is the hardest part, not the engineering itself. Staying on top of two separate statutory clocks, two sets of vendor contracts, and two sets of owner notifications is a real administrative burden for an all-volunteer board. This is the kind of scheduling and recordkeeping problem the $199 Board Compliance Kit is built to organize, tailored to your building's age, height, and coastal location, though the licensed engineer or architect still has to perform the actual inspection and study; the kit just keeps the deadlines, vendor documents, and owner notices straight.
What happens if a board skips or delays the SIRS?
Skipping the SIRS doesn't make the underlying structural funding problem go away. It just means the board is guessing at reserve amounts instead of using an engineer's numbers, and it likely puts the association out of compliance with FS 718.112's mandatory disclosure and funding requirements [1]. Associations that fail to complete a required SIRS on schedule can face difficulty later refinancing, selling units (some lenders and title companies now ask directly about SIRS and milestone status before closing), and insurance renewal, on top of any statutory penalties or enforcement action the state may pursue [1]. There's also a practical trap: boards that delay the SIRS often delay the special assessment conversation along with it, which means owners get less warning and less time to plan financially when the bill eventually comes. An engineer's report done two years early gives a board time to phase a reserve increase gradually instead of dropping a lump-sum assessment on owners with 60 days' notice. If your association missed a deadline or isn't sure where it stands, the right first call is your association's counsel, not a guess based on what a neighboring building did. Deadlines, phase-in relief, and penalty provisions have changed more than once since 2022, and county-level enforcement practices vary.
How do boards budget and communicate a SIRS-driven reserve increase to owners?
Once the SIRS numbers are in, the board has to build them into the annual budget as separate reserve line items for each covered component, per FS 718.112(2)(f) [1]. That budget then goes to owners, usually with meeting notice requirements under the condo statute's board meeting and notice provisions. The communication side matters as much as the math. Owners who get hit with a sudden assessment notice with no context tend to push back hard, sometimes with lawsuits or recall attempts. Boards that walk owners through the SIRS findings early get far less friction. A summary handout, a Q&A session, a clear comparison of "pay gradually through reserves" versus "pay a lump sum special assessment later" goes a long way. Our guide on reserve study for condo associations goes deeper into structuring a multi-year funding plan so a SIRS-driven increase doesn't have to land as a single painful special assessment.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment of a property's major shared components (roofs, structural elements, plumbing, elevators, pavement) that estimates each item's remaining life and replacement cost, then compares that against savings on hand. In Florida, the SIRS version under FS 718.112 makes the resulting reserve funding mandatory for condos and co-ops in buildings 3+ stories.
What is a reserve study for an HOA?
For Florida HOAs, a reserve study historically covered general common-area components at the board's discretion. Since 2023, FS 720.30185 requires HOAs with qualifying buildings to complete a structural inspection and reserve study similar to the condo SIRS, phased in over several years. Confirm your HOA's specific trigger date and thresholds with counsel.
What is an HOA assessment?
An HOA assessment is the regular fee (usually monthly or quarterly) owners pay to cover the association's operating budget and reserve contributions. It's distinct from a special assessment, which is a one-time extra charge levied to cover an unbudgeted or emergency cost, such as a SIRS-driven structural repair.
How much should an HOA have in reserves?
There's no universal percentage that fits every property. For Florida condos and co-ops covered by the SIRS mandate, structural components identified in the study must be funded at 100% of the calculated need under FS 718.112(2)(f)-(g). Outside that mandate, a common industry benchmark is roughly 70%+ funded relative to a full component-based plan, though that figure comes from general reserve-study practice, not statute.
How much does a reserve study cost?
Florida SIRS costs vary widely by building size and complexity. Industry-reported ranges run roughly $3,000 to $10,000 total for smaller associations (under 50 units), $8,000 to $20,000 for mid-size buildings, and $20,000 to $50,000+ for large or complex high-rises. Get multiple quotes from licensed engineers or architects before assuming a number.
Are HOA and condo special assessments tax deductible?
Generally no for a primary residence; special assessments for capital repairs typically add to your cost basis rather than becoming a current deduction, per IRS Publication 523 guidance on home basis. Rental property owners may deduct a repair-related portion in some cases. Talk to a CPA about your specific situation before assuming any deduction applies.
What buildings need a Florida SIRS?
Condominium and cooperative buildings three stories or taller need a structural integrity reserve study under FS 718.112(2)(g), regardless of distance from the coast. Buildings under three stories aren't covered by this specific mandate, though HOA buildings may face a separate requirement under FS 720.30185.
Is a SIRS the same as a milestone inspection?
No. A milestone inspection under FS 553.899 checks for substantial structural deterioration at year 25 (coastal) or 30, then every 10 years after. A SIRS under FS 718.112 is a reserve-funding study on its own 10-year clock. Many buildings need both, sometimes from the same engineering firm, but they're legally separate requirements.
Who is legally allowed to perform a SIRS in Florida?
Florida Statute 718.112(2)(g) requires the study be performed by a Florida-licensed engineer or architect. Boards should verify the individual's license status through the state's licensing lookup before signing a contract, and get a written scope confirming every statutory component is covered.
Can a board still waive or reduce reserves after a SIRS?
No, not for the structural components identified in the SIRS. Since the 2022 reforms, FS 718.112(2)(f) removed the ability of owners to vote to waive or reduce reserve funding for those specific line items once a SIRS has identified them, unlike the broader discretion that used to exist under prior law.
What happens if an association misses the SIRS deadline?
Missing the deadline can put the association out of compliance with FS 718.112's disclosure and funding rules, complicate unit sales and refinancing, and affect insurance renewal. Legislative relief provisions have shifted deadlines more than once since 2022, so confirm current status and any available extension with your association's counsel.
Does a SIRS cover HOA clubhouses or parking garages?
Not under the condo-specific FS 718.112 statute, since that applies to condominiums and cooperatives. But FS 720.30185, added in 2023, extends similar structural inspection and reserve study requirements to qualifying HOA buildings, including some multi-story structures HOAs own and insure. Check the phase-in dates with counsel.
