What is a structural integrity reserve study (SIRS)?

A structural integrity reserve study, almost everyone just says SIRS, is a specific type of reserve study Florida law now requires for condominium buildings three stories or higher. A licensed engineer or architect physically inspects a defined list of structural components (roof, load-bearing walls, floor, foundation, fireproofing, plumbing, electrical, waterproofing, and windows/exterior doors, among others) and estimates the remaining useful life and replacement cost of each. That data feeds a required funding schedule so the association isn't caught flat-footed when the roof needs replacing in year 18. The law lives in Florida Statutes section 718.112(2)(g). It came out of the 2022 and 2023 legislative sessions, the direct legislative response to the Champlain Towers South collapse in Surfside in June 2021, which killed 98 people ^[1]. Before that collapse, Florida condo associations could vote to waive or reduce reserve funding almost every year. SIRS closes that loophole for the structural items on the list, though it does not apply to every reserve line item in the budget. The statute is explicit about what counts: “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 exterior doors, and any additional item that has a deferred maintenance expense or replacement cost that exceeds $10,000 and impacts the structural integrity of the building” ^[1]. That last clause is a catch-all, and it's one of the more argued-over parts of the statute.

What is a reserve study?

A reserve study, in the general sense, is an inspection and financial analysis that tells a condo or HOA board what its major shared components are worth, how much life they have left, and how much money the association needs to be saving each year to replace them without a surprise special assessment. Think of it as a maintenance and savings plan rolled into one document. A typical reserve study has two halves. The physical analysis inventories the common elements (roofs, pavement, pools, elevators, painting, and so on), estimates useful life and remaining useful life for each, and prices out replacement in current dollars. The financial analysis then models a funding plan, either "full funding" (aiming to have 100% of the calculated obligation on hand at any point) or a "threshold funding" model that just avoids the fund hitting zero. Outside Florida, reserve studies are often optional or only loosely required, and many HOAs go years without one. Florida changed that calculus for condos specifically with SIRS, though HOAs (single-family and townhome associations governed by chapter 720, not 718) are not currently subject to the SIRS mandate. If your association is a straight HOA, our page on HOA reserve study requirements walks through what does and doesn't apply to you.

What is a reserve study for an HOA, and does SIRS apply to HOAs?

For an HOA, a reserve study serves the same basic purpose, it flags upcoming big-ticket replacements, roads, clubhouse roofs, retention ponds, and builds a savings schedule, but the legal requirement is different from condos. Florida's SIRS mandate under 718.112 applies to condominium associations, which are governed by chapter 718. Homeowners' associations governed by chapter 720 (typically single-family and townhome communities with individually owned land) are not subject to the SIRS requirement. That said, HOAs still need a reserve study for practical reasons even without a legal mandate. Boards that skip one tend to either underfund routine repairs or hit residents with an out-of-nowhere special assessment when the private road needs repaving. Many HOA governing documents already require periodic reserve studies or reserve funding at the board's discretion, so check your declaration and bylaws, and confirm the current legal landscape with your association's counsel, since Florida's legislature has amended chapter 718 reserve rules multiple times since 2022 and could touch chapter 720 again. Cooperatives (chapter 719) with buildings three stories or higher are also covered by the SIRS requirement, similarly to condos.

How much does a reserve study cost?

Costs vary a lot depending on building size, number of components inspected, and whether it's a basic reserve study or a full SIRS requiring a licensed engineer's structural inspection. There's no statewide fee schedule, so treat these as ranges from industry practice rather than fixed prices. A general (non-SIRS) reserve study for a small to mid-size community commonly runs somewhere in the $2,000 to $6,000+ range, depending on the number of components and whether it includes an on-site visual inspection or is a "desktop" update. A full SIRS, because it legally requires a licensed engineer or architect and covers specific structural systems in detail, tends to run higher, often quoted in the range of a few thousand dollars for a small building up into five figures for larger, more complex high-rises. DBPR does not publish a fee schedule for SIRS providers, so get at least two or three quotes from licensed firms and compare scope, more than price. The honest caveat: pricing data in this space is thin and mostly comes from association management companies and engineering firms quoting boards directly, not from any government survey. If a vendor gives you a number well outside these ranges, ask exactly what components they're inspecting and whether the report will satisfy the statutory SIRS requirements under 718.112(2)(g), more than a generic reserve template. Our reserve study and reserve study for condo association pages go deeper into what a compliant scope of work should include so you can compare quotes apples to apples.

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 your buildings and infrastructure. The honest answer is: enough to match what your reserve study (or SIRS) calculates as the funding requirement for each component, given its remaining useful life and replacement cost. For Florida condos subject to SIRS, the law is now specific on one point: associations may no longer vote to waive or reduce reserve funding for the structural components covered by the SIRS list. Fla. Stat. 718.112(2)(f)4 states that reserve funds for items included in a SIRS "may not be waived or reduced" (with narrow exceptions tied to the SIRS report itself and its funding schedule) ^[1]. That's a real shift from pre-2022 law, when owners could vote every year to underfund or skip reserves entirely. For everything outside the SIRS list, and for HOAs generally, associations still have more flexibility, and many under-reserve because it keeps dues artificially low in the short term. A rough industry rule of thumb some reserve professionals use is that a healthy reserve fund should be funded at 70% or more of its "fully funded" target, but that's a professional guideline, not a statutory number, and your reserve study is the only document that tells you your association's actual target.

What is an HOA assessment (regular vs. special)?

An HOA assessment is money the association charges owners, beyond or as part of regular dues, to cover association expenses. There are two basic types board members need to keep straight: regular (or "annual") assessments and special assessments. Regular assessments are the routine, budgeted charges, usually monthly or quarterly, that fund day-to-day operations and reserve contributions. They're set through the annual budget process laid out in the association's governing documents and, for condos, in chapter 718. Special assessments are one-time (or occasionally installment) charges levied outside the regular budget, typically to cover a shortfall, an emergency repair, or a large capital project the reserve fund can't fully cover. These are the assessments that make headlines, because they can run into the tens of thousands of dollars per unit when a building has deferred maintenance or failed to fund reserves adequately for years. Florida law requires notice of a board meeting where a special assessment will be considered to include a statement of the nature, estimated cost, and purpose of the assessment ^[2]. For a deeper breakdown of how these get levied and what owner rights look like, see our page on HOA special assessment.

What are HOA assessments used for, and how are they calculated?

Assessments fund everything from landscaping and insurance to reserve contributions and emergency repairs. For condos, chapter 718 requires the association's operating budget to include reserve accounts for capital expenditures and deferred maintenance, itemized by component, and requires those reserve line items to be funded per the SIRS schedule for structural components covered by the law ^{[1] [1]}. How much any individual owner pays is set by the association's declaration, typically apportioned by unit percentage of common expenses (often tied to square footage or the percentage interest listed in the declaration). Boards don't have unlimited discretion here; increases to regular assessments and the process for levying special assessments are both constrained by statute and by the association's own governing documents, so any dispute about calculation method is really a governing-document interpretation question best answered by association counsel, not a generic article.

Are HOA special assessments tax deductible?

Generally, no, not for the individual owner claiming a personal itemized deduction, and this is one of the most common misconceptions boards field from owners after a big special assessment hits. The IRS treats special assessments the way it treats most capital improvements to your property: they're generally not currently deductible as a personal expense, but they may add to your cost basis in the property, which can reduce capital gains tax when you eventually sell ^[3]. There are narrow exceptions. If a unit is a rental property, a portion of a special assessment tied to repairs (as opposed to capital improvements) may be deductible as a rental expense in the year paid, and capital-improvement-type assessments on a rental get depreciated over time rather than deducted immediately. IRS Publication 527 covers rental property expense and depreciation rules in more detail ^[3]. This is genuinely a tax question, not a condo-law question, so any owner with a real dollar amount at stake should talk to a CPA who can look at their specific situation, not rely on a board member's informal answer or, frankly, this article.

How does a SIRS differ from a milestone inspection?

They're related but not the same document, and boards mix them up constantly. A milestone inspection is a structural safety inspection required under Fla. Stat. 553.899 for condo and cooperative buildings three stories or more, due by the building's 30th year (or 25th year if within three miles of the coast), and every 10 years after. It's primarily a safety check: is the building structurally sound right now. A SIRS, by contrast, is a financial planning document built on a structural inspection, required under 718.112(2)(g), that determines how much money the association needs to reserve for the structural components over time. The two often get scheduled around the same timeframe and sometimes use overlapping inspection data, but they serve different statutory purposes: one is a pass/fail safety inspection, the other is a funding calculation. Boards juggling both deadlines at once should look at our milestone inspections hub for the full timeline by building age and coastal distance.

Who has to do the SIRS inspection, and how often?

The statute requires the SIRS to be performed by a licensed engineer or licensed architect, not by a board member, property manager, or generic reserve consultant without those credentials ^[1]. DBPR, Florida's Department of Business and Professional Regulation, licenses and regulates community association managers and oversees condo association compliance generally, though the licensing of engineers and architects themselves falls under separate state boards. The SIRS has to be completed and turned over to the board, then must be updated at least every 10 years, according to the statute's language ^[1]. Associations that fail to complete a SIRS on time can face real consequences, including the loss of the ability to waive reserves and potential liability exposure for the board, so tracking that 10-year clock matters as much as tracking the milestone inspection clock. This is exactly the kind of deadline tracking that gets lost in a board's shared drive between annual meetings. A Building-Specific Board Compliance Kit, a $199 one-time tool, organizes your building's specific SIRS and milestone deadlines, reserve line items, and required notices in one place so nothing slips through a board transition. It doesn't replace your licensed engineer or your association's attorney, it just keeps the paperwork and dates straight.

What happens if an association skips or delays its SIRS?

Skipping the SIRS doesn't make the underlying structural problem go away, it just means the board finds out about a failing roof or a corroding balcony support later, usually more expensively, and often at the same moment reserves are needed most. Beyond the practical risk, Florida law has been amended more than once since 2022 to tighten the reserve waiver rules specifically because associations were treating reserve funding as optional for years or decades. Associations that are behind should talk to their attorney about their specific exposure rather than guess, because the statute has seen multiple legislative tweaks (including relief measures debated in 2023 and 2024 sessions around phasing in funding for financially strained associations). Our page on Florida condo reserve fund relief covers what limited relief options have existed and what boards should confirm currently applies, since this is an area where "confirm with your association's counsel and county" isn't boilerplate, it's genuinely necessary given how often this law has moved.

How do I know if my building needs a SIRS this year?

Check three things: building height, structure type, and when your last SIRS or milestone inspection was completed. The SIRS mandate applies to condominium (and cooperative) buildings three stories or higher under chapter 718 (and the parallel cooperative statute), regardless of coastal proximity, unlike milestone inspections, which have a coastal-distance trigger for the 25-year versus 30-year deadline. If your association has never had a SIRS done, or isn't sure whether the last one meets the current statutory component list, that's a conversation for your board to have with a licensed engineer and your association's attorney soon, not next fiscal year. The statute's deadlines and waiver rules have shifted since 2022, so don't assume last year's advice still reflects current law without confirming it.

Frequently asked questions

What is a reserve study for HOA associations specifically?

For an HOA, a reserve study inspects shared assets like roads, clubhouses, and pools, estimates remaining life and replacement cost, and builds a savings schedule. Unlike condo SIRS under Fla. Stat. 718.112, HOAs (chapter 720) generally aren't under a statewide mandate to complete one, though governing documents may require it and skipping one still risks surprise special assessments.

What is a reserve study, in plain terms?

A reserve study is a report that inventories an association's major shared components, estimates how many years of life each has left and what replacement will cost, then calculates how much money needs to be saved annually. It's the financial planning backbone for avoiding emergency special assessments.

What is an HOA assessment versus a condo assessment?

Both terms describe money owners pay beyond base dues. Regular assessments are budgeted, recurring charges. Special assessments are one-time charges for shortfalls or emergencies not covered by the budget or reserves. The mechanics for condos are governed by Fla. Stat. chapter 718; HOAs fall under chapter 720.

How much should an HOA have in reserves?

There's no universal dollar figure; it depends on your specific components' age and replacement cost, per your reserve study. Some reserve professionals use 70% of "fully funded" as a rough health benchmark, but that's an industry guideline, not a Florida statutory requirement, and only applies loosely outside the SIRS-covered condo components.

How much does a reserve study cost in Florida?

General reserve studies commonly run about $2,000 to $6,000+ depending on scope. A full SIRS, requiring a licensed engineer or architect, often costs more due to the required structural inspection, ranging from a few thousand dollars for small buildings to five figures for large high-rises. Get multiple quotes and compare scope of work, more than price.

Are HOA or condo special assessments tax deductible?

Usually not as a direct personal deduction. The IRS generally treats special assessments as adding to your property's cost basis rather than a current deduction, per IRS Publication 527 guidance on rental property; exceptions can apply for rental units where a portion may be deductible or depreciated. Talk to a CPA about your specific situation.

Is a SIRS the same as a milestone inspection?

No. A milestone inspection (Fla. Stat. 553.899) is a structural safety check due at year 30 (or 25 near the coast) and every 10 years after. A SIRS (Fla. Stat. 718.112(2)(g)) is a reserve funding study based on a structural inspection of specific components, also updated at least every 10 years. They often get scheduled together but serve different legal purposes.

Does SIRS apply to my HOA if it has townhomes over three stories?

It depends on how the community is legally structured. SIRS under 718.112 applies to condominium associations governed by chapter 718. If your townhome community is legally a condominium (owners hold units, not fee-simple land), SIRS likely applies at 3+ stories; if it's a true HOA under chapter 720, it currently doesn't. Confirm your association's legal structure with counsel.

Can my association still waive reserve funding under Florida law?

For structural components covered by a completed SIRS, no. Fla. Stat. 718.112(2)(f)4 states those reserves "may not be waived or reduced" except in narrow circumstances tied to the SIRS report itself. For non-SIRS reserve items, some waiver flexibility may still exist depending on current law, so confirm specifics with counsel.

Who is qualified to perform a SIRS in Florida?

The statute requires a licensed engineer or licensed architect to perform the structural inspection underlying the SIRS. A property manager, board member, or general reserve consultant without that license cannot legally complete the required inspection component, even if they assist with the financial or reporting side.

What components does a SIRS have to cover?

At minimum: roof, load-bearing walls or primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, windows and exterior doors, plus any additional item over $10,000 in cost that affects structural integrity, per Fla. Stat. 718.112(2)(g).

How often does a SIRS need to be updated?

At least every 10 years, based on the requirements under Fla. Stat. 718.112(2)(g). Some boards choose to update sooner after major repairs or a milestone inspection reveals new issues, but the statutory floor is a 10-year cycle.
