TL;DR
A Structural Integrity Reserve Study (SIRS) is a visual inspection of a Florida condo building's structural components (roof, load-bearing walls, waterproofing, plumbing, electrical, and more) by a licensed engineer or architect, done at least every 10 years, that sets mandatory, non-waivable reserve funding levels under Fla. Stat. 718.112. It's required for condos 3 stories or taller.
What is a structural integrity reserve study (SIRS)?
A structural integrity reserve study, or SIRS, is a formal inspection and funding analysis for a condominium building that's 3 stories or more above ground. A licensed engineer or architect physically examines specific structural components and estimates the remaining useful life and replacement cost of each one. That data then drives how much money your association legally has to keep in reserves. Florida Statute 718.112(2)(g) spells out exactly what has to get studied: roof, load-bearing walls or other primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, windows, 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]. This is not the same thing as your building's milestone inspection, though the two often get lumped together. The milestone inspection (also created after the 2021 Champlain Towers South collapse in Surfside) checks structural safety at 25 or 30 years depending on coastal proximity. The SIRS is about reserve funding. A lot of associations hire the same engineering firm to do both at once, which is smart from a cost standpoint, but they're two distinct statutory requirements with two distinct purposes. See our full breakdown of milestone inspections if your building is approaching that 25 or 30-year window.
What is a reserve study?
A reserve study, in the general sense (outside of Florida's specific SIRS mandate), is a financial planning document. It looks at every major shared component of a building or community, roofs, pools, pavement, elevators, HVAC systems, and estimates when each will need repair or replacement and how much that will cost. The study then recommends how much money the association should be setting aside each year so the cash is there when the bill comes due. Most states don't require reserve studies by law. Florida's SIRS requirement is more prescriptive than most: it names the exact components that must be studied, requires a licensed engineer or architect to do the work, and ties the funding requirement directly to statute rather than leaving it to board discretion [1]. A general reserve study (sometimes just called a "reserve study for an HOA") can also include non-structural stuff, landscaping, painting, fencing, amenities. Florida condos still need to reserve for those items too, they just aren't part of the SIRS itself. Read more in our reserve study overview.
What is a reserve study for an HOA, and does Florida require one?
For homeowners associations (as opposed to condos), the SIRS mandate does not apply. Fla. Stat. 718.112 is specifically a condominium statute, part of Chapter 718. HOAs are governed under Chapter 720, and as of the current statute, Chapter 720 does not impose the same structural inspection or SIRS requirement on single-family or townhome HOAs [2]. That said, plenty of HOAs, especially ones with condo-style buildings, attached townhomes, or shared structural elements, choose to do a reserve study anyway because it's good practice and because lenders and insurers increasingly ask for one. If your HOA has 3-story-plus buildings that are legally condominiums under the declaration (this happens more than people think), you may actually be subject to Chapter 718 requirements regardless of what your community calls itself. Check with your association's counsel to confirm which chapter actually governs your property. See our HOA reserve study guide for more on how this plays out for community associations that aren't traditional condos.
Which buildings actually need a SIRS?
The SIRS requirement applies to condominium associations with buildings 3 stories or more in height, regardless of the building's age, according to Fla. Stat. 718.112(2)(g) [1]. There's no coastal-proximity carve-out for SIRS itself (that distinction matters more for milestone inspection timing, which is 25 years for buildings within 3 miles of the coast and 30 years for everything else, per Fla. Stat. 553.899 [3]). The law requires associations to complete their first SIRS by December 31, 2024, for buildings that existed as of that deadline, and building reserve funding based on that SIRS had to be in place with the 2025 fiscal year budget. After that, a new SIRS is required at least every 10 years [1]. Smaller condo buildings (1 or 2 stories) and detached single-family HOAs are not subject to SIRS. Timeshares are also excluded under the statute [1].
What is an HOA assessment?
An HOA assessment is money the association charges each unit owner or homeowner to cover shared expenses. There are two basic types: regular assessments (the routine monthly or quarterly dues that fund operating costs and reserves) and special assessments (one-time or short-term charges levied to cover an unexpected or large expense that the reserve fund can't absorb). Assessments are usually calculated per the association's declaration, often based on unit square footage or an equal per-unit share, and the board's authority to levy them comes from both the governing documents and Chapter 718 (for condos) or Chapter 720 (for HOAs). When people ask "what are HOA assessments" in the context of a SIRS or milestone inspection, they're usually asking about special assessments specifically, because a failed SIRS finding or an expensive structural repair often means the reserve fund alone can't cover it, and the board has to go back to owners for more cash. See HOA special assessment for how that process works step by step.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure that applies to every building; it depends entirely on the size, age, and condition of the components in your SIRS and reserve study. What the statute does say is that reserve funding for the SIRS-required components can no longer be waived or reduced by member vote, starting with the fiscal year budget adopted after your first SIRS [1]. Before recent amendments, associations could vote to underfund or skip reserves entirely; for structural items covered by SIRS, that option is gone. A reasonable planning approach: your reserve study (whether SIRS-driven or general) will produce a schedule showing the estimated remaining useful life and replacement cost for each component. Full funding means contributing enough each year that the balance tracks the straight-line depreciation of that component. Many associations aim for something close to full funding on structural items now precisely because the law took the underfunding option away. There's no single national standard for what share of a budget should go to reserves. It depends heavily on a building's age, roof and system condition, and how many big-ticket components are approaching end of life at once. That's exactly why the statute requires an actual engineer's inspection rather than a formula: a 15-year-old mid-rise and a 45-year-old oceanfront tower have almost nothing in common on this question. The honest answer for a specific building only comes from an actual reserve study. There's no shortcut number that works for every property.
How much does a reserve study cost?
Costs vary widely by building size, number of components studied, and whether you're combining the SIRS with your milestone inspection. Community association managers and engineering firms commonly describe a broad range from roughly $2,000 for a small, straightforward property up into the tens of thousands for a large or architecturally complex high-rise, but there's no single authoritative national price survey to cite, and boards should treat any number here as a rough planning range rather than a quote. For SIRS specifically, because it requires a licensed engineer or architect to do a hands-on visual inspection of every listed structural component, costs tend to run toward the higher end of whatever range a firm quotes, and combining it with a milestone inspection (many firms do both simultaneously) can save on mobilization and site-visit costs since the engineer is already on site. DBPR (Florida's Department of Business and Professional Regulation) licenses community association managers under Fla. Stat. 468.431 and maintains a license verification system boards can use to confirm a firm's credentials before signing a contract [4]. Get at least two or three quotes from licensed firms before committing. Prices vary more than you'd expect for what sounds like a standardized service, largely because building size, number of distinct structural systems, and travel/mobilization costs differ so much property to property.
Are HOA special assessments tax deductible?
For most owners, no. Special assessments paid to a homeowners or condo association are generally treated as a capital improvement to your property rather than a deductible expense, similar to how you'd treat money spent improving your own home. The IRS does not allow a deduction for regular HOA dues or special assessments on a personal residence [5]. There are narrow exceptions. If you rent out the unit, a portion of assessments tied to necessary repairs and maintenance on the rental property may be deductible as a rental expense, and assessments that fund a genuine capital improvement can sometimes be added to your cost basis, which reduces capital gains tax when you eventually sell. The IRS's Publication 527 covers rental property expense rules in more detail [5]. This is genuinely a case where you should talk to a CPA rather than guess. The deductibility question turns on how the assessment is characterized (repair vs. capital improvement), whether the unit is a personal residence or a rental, and your individual tax situation. Don't rely on a board member's informal answer here, and don't rely on this article as tax advice either.
What happens if the SIRS finds a problem?
If the inspecting engineer or architect identifies a deficiency, deteriorated component, or safety concern, that finding becomes part of the SIRS report and typically drives an updated reserve funding schedule. Depending on severity, it can also trigger a required repair timeline separate from the reserve fund conversation, particularly if the finding overlaps with milestone inspection structural concerns. The board's job at that point is straightforward on paper and hard in practice: get the engineer's full written scope of repair, get contractor bids, figure out what reserves can cover versus what needs a special assessment or loan, and communicate a timeline to owners. Boards that try to handle this informally (a hallway conversation, a vague email) tend to get sued or recalled. Owners are legally entitled to see the SIRS report and the resulting funding plan. This is exactly the kind of moment where having your inspection dates, funding deadlines, and required owner disclosures organized in one place matters. A $199 one-time Building-Specific Board Compliance Kit at /board-kit-builder won't do the engineering (that has to be a licensed professional, always), but it organizes the SIRS findings, milestone deadlines, and owner communication requirements into one schedule so the board isn't reconstructing the timeline from memory during a stressful special assessment vote.
Can a board waive or reduce SIRS reserve funding?
No, not anymore, at least not for the structural components covered by SIRS. Prior to the 2022 and 2023 legislative changes, Florida condo associations could vote to waive or reduce reserve funding almost entirely. After Surfside, the legislature closed that door specifically for SIRS components. Fla. Stat. 718.112(2)(f)4 states that reserve funds for items included in the SIRS "may not be waived or reduced" after the association's first structural integrity reserve study is completed [1]. This is arguably the single biggest practical change in Florida condo law post-Surfside: reserve underfunding, which was legal and common for decades, is no longer an option for structural components. Boards can still vote to waive or reduce reserves for non-SIRS items (things like painting, landscaping, or amenities not tied to structural safety), but that carve-out doesn't extend to roofs, load-bearing walls, waterproofing, or the other statutorily listed structural components. See our guide on Florida condo reserve fund relief for how some associations are handling the resulting cash-flow squeeze, including financing options some legislators have floated.
SIRS vs. milestone inspection vs. general reserve study: how they differ
| Requirement | What it checks | Who performs it | Trigger / timing | Governing statute | |
|---|---|---|---|---|---|
| Milestone inspection | Overall structural safety and integrity of the building | Licensed engineer or architect | 25 years (within 3 miles of coast) or 30 years, then every 10 years | Fla. Stat. 553.899 [3] | |
| SIRS | Specific listed structural/mechanical components and their reserve funding needs | Licensed engineer or architect | First SIRS due Dec. 31, 2024; every 10 years after | Fla. Stat. 718.112(2)(g) [1] | |
| General reserve study | All shared components, structural and non-structural (pools, paving, amenities) | Reserve specialist, engineer, or CAM depending on scope | Best practice, often annual update | Not separately mandated in Chapter 718 beyond SIRS items | The practical takeaway: your milestone inspection and SIRS often get bundled into one engineering engagement because the same professional is climbing the same building looking at similar structural systems. But they produce two different documents that answer two different legal questions, one about immediate safety, one about long-term funding. Your general reserve study is broader still and covers items the statute doesn't require funding rules for, but that your budget still needs to plan around. |
Who can perform a SIRS in Florida?
The statute requires the study be performed by a licensed engineer or architect. Florida licenses engineers under Fla. Stat. Chapter 471 through the Florida Board of Professional Engineers, and boards can verify an individual license status through the Board's online lookup before signing a contract . Don't hire based on a sales pitch alone. Ask for the license number, verify it through the state's lookup tool, and ask for references from other associations of similar size and age. Given that the SIRS now legally locks in your reserve funding for a decade, getting a rushed or low-quality study is expensive to live with.
Frequently asked questions
What is a structural integrity reserve study in Florida?
It's a mandatory inspection of a Florida condo building's structural components (roof, load-bearing walls, waterproofing, plumbing, electrical, and similar systems) done by a licensed engineer or architect, required for buildings 3 stories or taller under Fla. Stat. 718.112(2)(g). The findings set legally binding reserve funding levels that boards can no longer waive or reduce.
What is a reserve study?
A reserve study is a report that inventories a building's major shared components, estimates each one's remaining life and replacement cost, and recommends annual funding levels so money is available when repairs come due. Florida's SIRS is a specific, statute-driven version of this for condo structural components.
What is a reserve study for an HOA?
For a traditional HOA (governed under Chapter 720), a reserve study is a voluntary financial planning tool, not a legal mandate, since Florida's SIRS requirement applies to condominiums under Chapter 718. Many HOAs do one anyway for budgeting accuracy and because lenders sometimes ask for it.
What is an HOA assessment?
An HOA assessment is a fee charged to owners to fund association expenses. Regular assessments cover routine operating costs and reserves; special assessments are one-time charges levied when a large expense (like a SIRS-driven structural repair) exceeds what reserves can cover.
How much should an HOA have in reserves?
There's no universal dollar figure; it depends on your building's actual components, age, and reserve study findings. For Florida condo structural items covered by SIRS, full, non-waivable funding is now required by statute rather than left to board discretion.
How much does a reserve study cost?
Costs vary widely by building size and complexity, commonly cited in a broad range from roughly $2,000 for smaller properties up into the tens of thousands for large or complex high-rises. SIRS-specific studies, which require a licensed engineer's hands-on inspection, tend toward the higher end. Get multiple quotes since pricing varies significantly by property.
Are HOA special assessments tax deductible?
Generally no, for a personal residence. The IRS treats most special assessments as capital improvements, not deductible expenses. Rental property owners may deduct a portion tied to repairs, and capital-improvement assessments can sometimes be added to cost basis. Confirm with a CPA.
Does every Florida condo need a SIRS?
Only condominium buildings 3 stories or more in height need a SIRS under Fla. Stat. 718.112(2)(g). Buildings under 3 stories, single-family HOAs, and timeshares are excluded from this specific requirement.
What's the difference between a SIRS and a milestone inspection?
A milestone inspection (Fla. Stat. 553.899) checks overall structural safety at 25 or 30 years depending on coastal distance. A SIRS (Fla. Stat. 718.112) checks specific listed structural components and sets mandatory reserve funding. They're often done together but are legally separate requirements.
Can a Florida condo board still waive reserve funding?
Not for components covered by the SIRS. Fla. Stat. 718.112(2)(f)4 prohibits waiving or reducing reserves for SIRS items once the first study is completed. Boards can still vote to waive reserves for non-structural items outside the SIRS list.
When was the first Florida SIRS deadline?
Associations subject to the requirement had to complete their first SIRS by December 31, 2024, with the resulting non-waivable reserve funding reflected starting in the fiscal year 2025 budget. A new SIRS is required at least every 10 years after that.
Who is qualified to perform a SIRS?
Only a licensed engineer or architect can perform a Florida SIRS. Boards should verify credentials through the Florida Board of Professional Engineers or DBPR before signing a contract, since a flawed or rushed study can lock in incorrect reserve funding for up to a decade.
