TL;DR
A Structural Integrity Reserve Study (SIRS) is a Florida-required inspection of 25 specific building components that sets mandatory, non-waivable reserve funding for condo associations in buildings 3 stories or taller. Most associations needed one completed by December 31, 2024, per Florida Statutes section 718.112. It costs roughly $2,000 to $10,000+ depending on building size, and must be redone every 10 years.
What is a SIRS in Florida?
A Structural Integrity Reserve Study, or SIRS, is a study of a condominium building's major structural and safety components, done to figure out how much money the association needs to be setting aside in reserves for future repair and replacement. Florida created this requirement after the Champlain Towers South collapse in Surfside in June 2021, which killed 98 people. It is not the same thing as a milestone inspection, though the two often get confused because they came out of the same legislation. Under Florida Statutes section 718.112(2)(g), a SIRS must be performed for buildings that are three stories or more in height and must cover 25 specific items: roof, load-bearing walls, primary structural members, primary structural systems, fireproofing and fire protection systems, plumbing, electrical systems, 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]. The study has to be prepared by a licensed engineer or architect. The SIRS produces two things a board actually uses: a physical condition assessment of those 25 components, and a funding schedule showing what reserve contribution level is needed for each one so the association isn't caught flat-footed when a roof or a structural repair comes due. That funding number is the part that changed condo life in Florida. It's not a suggestion anymore.
What is a reserve study?
A reserve study, in general, is a financial and physical assessment that estimates the remaining useful life of an association's major shared components (roofs, paving, pools, elevators, painting, structural elements) and calculates how much money should be saved each year to pay for replacing them without a surprise special assessment. Every community association, whether it's a condo, an HOA, or a co-op, benefits from one, but Florida law treats them very differently depending on the type of property. For a regular HOA reserve study (not tied to SIRS), there's no statewide legal requirement in Florida that HOAs fund reserves at all unless the declaration says so or the members vote to fund them. Chapter 720 of the Florida Statutes governs homeowners' associations and gives boards more flexibility, and often less accountability, on this point [2]. For condos governed by Chapter 718, reserve studies are far more regulated, and the SIRS requirement layered a mandatory, non-waivable version on top of the older, more general reserve rules for buildings that hit the height and age thresholds. If you want the mechanics of a standard reserve study process, 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 looks at the same basic idea (inventory the components, estimate remaining life, estimate replacement cost, recommend a funding plan) but it applies to single-family and townhome communities governed by Chapter 720, not condo buildings governed by Chapter 718. HOAs are not subject to the SIRS law at all. SIRS only applies to condominium associations with buildings three stories or higher. That said, plenty of HOAs with shared structures, like clubhouses, gated entries, or attached townhome buildings, choose to commission a reserve study voluntarily, because underfunded reserves are one of the top reasons special assessments blindside homeowners. Florida's Division of Florida Condominiums, Timeshares, and Mobile Homes, part of the Department of Business and Professional Regulation, oversees condo compliance under Chapter 718, including SIRS-related recordkeeping and financial reporting requirements, but has a much lighter regulatory footprint over HOAs [3]. See hoa reserve study for how that process typically works when a homeowners association decides to commission one on its own.
How much does a reserve study or SIRS cost in Florida?
Costs vary a lot by building size, age, and how many components need engineering analysis. For a full SIRS on a mid-size condo (say, 50 to 150 units, 3 to 10 stories), reasonable market ranges reported by engineering firms and condo attorneys run roughly $2,000 to $10,000 for smaller buildings, and up into the $15,000 to $30,000+ range for larger, older, or more architecturally complex high-rises. Waterfront and coastal buildings often land at the higher end because of added corrosion, waterproofing, and structural review. There's no statewide fee schedule; the law doesn't set a price, and no state agency publishes official cost benchmarks, so treat any number you see (including this one) as a market range, not a mandated figure. Get at least two or three quotes from licensed engineers or architects who do this work regularly in your county, since coastal exposure, elevator count, and parking structure complexity all move the price. A standard (non-SIRS) reserve study for an HOA tends to be cheaper, often $1,000 to $4,000, because it doesn't require the same level of engineering-grade structural evaluation as SIRS does. Either way, this is a one-time hiring decision your board makes carefully. A reserve study for condo association breaks down what a good scope of work should include so you don't get a bare-bones report that leaves your board guessing.
When was the SIRS deadline, and did it change?
The original deadline for most condo associations to complete their first SIRS was December 31, 2024, tied to milestone inspection timelines under section 718.112 [1]. Buildings were required to complete a SIRS before turning over reserve funding decisions to a waived or reduced-funding vote, and the underlying reserve funding for the 25 SIRS components became fully mandatory starting with the fiscal year following the study. Florida lawmakers have adjusted deadlines and funding phase-ins more than once since the law passed in 2022 as SB 4-D, later amended by HB 1021 in 2023 and further legislation in 2024 and 2025 [4]. These sessions have adjusted timelines and allowed some flexibility for associations that couldn't complete inspections in time. Because these dates keep shifting through legislative sessions, don't rely on a blog post (including this one) for your building's exact current deadline. Confirm the current deadline with your association's counsel, your community association manager, and your county building department, since some counties also layered on their own inspection timing requirements. Our florida condo reserve fund relief article tracks the legislative changes to funding phase-in rules in more detail.
How much should an HOA or condo have in reserves?
There's no single dollar figure or percentage that's "right" for every association, because it depends entirely on the age, size, and condition of the components you're responsible for maintaining. What matters is whether your reserve funding matches what a professional study says you'll actually need. For condos under SIRS, the law requires funding based on the study's findings for each of the 25 components, calculated using either the straight-line method or another actuarial method that doesn't defer the true cost. Florida Statutes section 718.112(2)(f) prohibits condo boards from voting to waive or reduce reserves for the SIRS-required components once the study is done; that override, which used to be common at annual meetings, is gone for these specific line items [1]. For HOAs and for condo components outside the SIRS list, funding levels are still mostly a board and membership decision, guided by whatever reserve study (if any) you've commissioned. A rough industry rule of thumb some reserve specialists use is that reserves should be funded to somewhere around 70% or more of the "fully funded" level calculated in the study, though this isn't a legal standard in Florida, just a common benchmark used in the reserve study industry nationally [5]. Underfunded reserves are the single biggest driver of large special assessments, so if your last study is more than a few years old, or you've never had one, that's worth fixing before a crisis forces the issue.
What is an HOA assessment, and what's the difference between regular and special assessments?
An HOA assessment (or condo assessment) is a fee the association charges owners to cover operating costs and reserve contributions. There are two basic kinds. A regular assessment is the recurring monthly or quarterly fee every owner pays as part of normal membership, covering things like landscaping, insurance, management, utilities, and reserve funding. A special assessment is a one-time (or limited-duration) extra charge levied when the regular budget and reserves aren't enough to cover an unexpected or large expense, like a roof replacement, storm damage, or a SIRS-driven repair that reserves hadn't caught up to yet. Boards typically levy special assessments under authority granted by the declaration and by Chapter 718 (for condos) or Chapter 720 (for HOAs), and the amount owed is usually allocated by the same percentage formula used for regular assessments unless the documents say otherwise. Confirm the exact assessment authority and notice requirements in your own declaration and bylaws with your association's counsel, since procedural rules (how much notice, whether a vote is required, payment plan options) vary by community and by document language, more than by statute. For a full walkthrough of how special assessments actually get triggered, communicated, and collected, see hoa special assessment.
Are HOA and condo special assessments tax deductible?
Generally, no, not for a personal residence. Special assessments for repairs, reserves, or capital improvements on a home you live in are typically treated like other non-deductible homeownership costs (similar to regular HOA dues), consistent with IRS guidance in Publication 530 on deductible and non-deductible home expenses for owners [6]. The IRS doesn't have a Florida-specific rule here; this is federal tax law that applies nationwide. There are exceptions. If the unit is a rental property, special assessments may be deductible as a business expense, or depreciated as a capital improvement, depending on what the assessment paid for, per IRS Publication 527 on rental property [6]. If part of your home is used for a qualifying home office, a portion may be deductible under home office rules. And if a special assessment pays for a casualty-loss-related repair (say, storm damage) there can be narrow deduction paths tied to federally declared disaster areas, but these are specific and limited, not a general rule. This isn't tax advice, and the line between "repair" and "capital improvement" affects the answer. Talk to a CPA who handles real estate before assuming either way, especially if the assessment is large enough to matter on your return.
Does SIRS apply to my building, and who is exempt?
SIRS applies to condominium associations with at least one building that is three stories or more in height, regardless of the building's total unit count. Single-family homes, duplexes, triplexes, and townhomes that aren't part of a condo form of ownership are not covered by SIRS, because the law specifically targets condominium buildings under Chapter 718. There is a narrow exemption for buildings that don't have units above the ground floor, and some very small condo associations (fewer than a certain number of units, check current statutory language) have had different phase-in treatment during the legislature's several rounds of amendments. Because the exemption language has been revised more than once since 2022, don't assume your building qualifies for an exemption based on an old article or a neighbor's building. Pull the current text of section 718.112 from the Florida Senate's official statutes site and confirm applicability with your association's counsel [1]. Cooperatives (co-ops) have a parallel but separate set of structural inspection requirements under Chapter 719, and the details differ slightly, so don't assume co-op rules mirror condo rules exactly.
How does SIRS relate to the milestone inspection?
They're related but distinct, and mixing them up is one of the most common mistakes boards make. The milestone inspection, required under Florida Statutes section 553.899, is a structural safety inspection performed at 30 years after the building's certificate of occupancy (or 25 years if the building is within three miles of the coast), and then every 10 years after that [7]. It focuses on structural integrity and safety, done in two phases, with Phase 2 (more invasive testing) triggered if Phase 1 finds substantial structural deterioration. SIRS, by contrast, is triggered by building height (three stories or more) rather than age, and it feeds directly into reserve funding requirements rather than being purely a safety check. A building can need a milestone inspection without needing SIRS (though in practice most condo buildings 3+ stories need both), and the two reports are often prepared around the same time by the same engineering firm to save on inspection costs. Boards sometimes get one report and think they've covered both requirements. They haven't, necessarily. Confirm with your engineer and your association's counsel that both the milestone inspection scope and the SIRS component list are fully addressed, since a milestone report alone doesn't satisfy the SIRS reserve funding calculation requirement.
What happens if a board doesn't complete the SIRS on time?
Consequences vary depending on how far behind an association is and how the local building department handles enforcement, but the general pattern under Florida law is that non-compliance opens the board up to potential liability, complicates unit sales and mortgage approvals (many lenders and title companies now ask for SIRS and milestone status before closing), and removes the association's ability to waive reserve funding for the required components. Florida's Division of Florida Condominiums, Timeshares, and Mobile Homes, which regulates condo associations under Chapter 718, can pursue enforcement action against associations and, in some circumstances, board members for statutory violations, including recordkeeping and reserve disclosure failures tied to SIRS [3]. Local building officials also have authority over milestone inspection compliance and can require corrective action if a building isn't inspected on schedule. The practical risk is usually less about a specific fine and more about exposure: an association that skips SIRS and then has a structural failure, or gets caught mid-sale without documentation, is in a much worse legal and financial position than one that's current. If your board is behind, the fix isn't complicated, it's just work: hire the licensed engineer, get the study scheduled, and start documenting the process now rather than waiting for a resale to force the issue.
How do boards actually organize and track SIRS and reserve deadlines?
Most boards run into trouble not because the law is unclear, but because tracking deadlines, contractor bids, owner notices, and reserve schedule updates across a volunteer board with turnover every year or two is genuinely hard. Nobody signed up to be a compliance officer when they ran for the board. The basics that matter regardless of what tools you use: keep a written record of when your milestone inspection and SIRS are due (based on your building's certificate of occupancy date and coastal proximity), keep copies of every engineer's report, keep minutes showing the board reviewed the SIRS funding requirements before setting the budget, and give owners the required advance notice before any board meeting where a special assessment is discussed. BoardDeadline built a $199 one-time Building-Specific Board Compliance Kit for exactly this gap. It doesn't replace your engineer, your CPA, or your attorney, and it doesn't render any compliance verdict about your building or interpret your governing documents. What it does is organize your building's specific milestone and SIRS deadlines, keep a schedule your board can actually follow, and help you communicate clearly with owners about what's due and when. If your board is trying to get ahead of a deadline instead of scrambling before one, the board-kit-builder is worth a look.
What should a board do first if it hasn't started SIRS or a reserve study yet?
Start with the building's certificate of occupancy date and its distance from the coast; those two facts determine your milestone inspection timeline under section 553.899, and they usually determine your SIRS urgency too, since most associations that need a milestone inspection also need SIRS [7]. Pull that paperwork before you do anything else. Next, get quotes from at least two licensed engineers or architects who do SIRS work in your county; ask specifically about their experience with buildings similar in age, height, and construction type to yours, since a firm that mostly does single-family inspections may not have the right structural engineering background for a 12-story tower. Then loop in your association's counsel early, not after the report comes back. Counsel can tell you what your specific declaration requires for notice, voting, and assessment authority, none of which a statute or a blog article can answer for your specific building. Once the SIRS is done, your board's real job starts: building the funding into the budget, communicating clearly with owners about what it means for their assessments, and not letting the report sit in a drawer.
Frequently asked questions
What is a reserve study?
A reserve study is a physical and financial assessment of a community association's major shared components (roofs, paving, structural elements, amenities) that estimates remaining useful life and recommends a funding schedule so the association can pay for future repairs without a surprise special assessment.
What is a reserve study for an HOA?
For an HOA under Florida's Chapter 720, a reserve study is a voluntary financial planning tool (unless governing documents require it) that inventories shared components and recommends annual reserve contributions. Unlike condo SIRS, Florida doesn't legally mandate HOA reserve studies or reserve funding statewide.
What is an HOA assessment?
An HOA assessment is a fee charged to owners to fund association operations and reserves. Regular assessments are recurring dues; special assessments are one-time or limited charges levied for unexpected or large expenses that regular budgets and reserves don't cover.
What is a SIRS in Florida condo law?
SIRS stands for Structural Integrity Reserve Study. It's a mandatory Florida study, required under Florida Statutes section 718.112, of 25 specific building components for condos three stories or taller, used to set non-waivable minimum reserve funding levels.
How much should an HOA have in reserves?
There's no fixed statewide dollar figure. The right amount depends on your reserve study's findings for your specific components. A commonly cited industry benchmark is funding to roughly 70% or more of the fully-funded level, though this is an industry guideline, not Florida law, for HOAs.
How much does a reserve study cost in Florida?
A full condo SIRS typically runs $2,000 to $10,000 for smaller buildings and $15,000 to $30,000+ for larger, complex, or coastal high-rises. Standard HOA reserve studies (non-SIRS) tend to run $1,000 to $4,000. Always get multiple licensed-professional quotes.
Are HOA special assessments tax deductible?
Generally no, for a personal residence. Special assessments are typically treated like non-deductible homeownership costs under IRS rules. Exceptions can apply for rental properties, qualifying home offices, or certain casualty-loss situations. Consult a CPA before assuming deductibility.
What's the difference between a milestone inspection and SIRS?
The milestone inspection (Florida Statutes 553.899) is a structural safety inspection triggered by building age (30 years, or 25 years if within 3 miles of the coast). SIRS is triggered by building height (3+ stories) and drives mandatory reserve funding for 25 specific components, more than a safety check.
What was the deadline for Florida condos to complete SIRS?
The original statutory deadline for most associations was December 31, 2024, but Florida's legislature has amended reserve and inspection deadlines multiple times since the law passed in 2022. Confirm your building's current deadline with your association's counsel and local building department.
Which condo buildings are exempt from Florida's SIRS requirement?
SIRS applies to condo buildings three stories or more in height. Buildings without units above the ground floor and some very small associations have had different phase-in or exemption treatment across several legislative amendments. Confirm current exemption language in Florida Statutes section 718.112 with your association's counsel.
Can a condo board vote to waive SIRS reserve funding?
No. Once a SIRS is completed, Florida Statutes section 718.112(2)(f) prohibits the board or membership from voting to waive or reduce reserve funding for the 25 SIRS-required components. This override, once common at annual meetings, no longer applies to those specific components.
Who can perform a SIRS in Florida?
A Structural Integrity Reserve Study must be prepared by a licensed engineer or architect, per Florida Statutes section 718.112(2)(g). Boards should get multiple quotes and confirm the professional has experience with buildings of similar age, height, and construction type.
Does SIRS apply to HOAs or just condos?
SIRS applies only to condominium associations under Florida Statutes Chapter 718, not to homeowners associations under Chapter 720. HOAs are not subject to the SIRS requirement regardless of building height, though some HOAs with attached structures voluntarily commission similar studies.
