TL;DR
A SIRS (structural integrity reserve study) is a Florida-required inspection of a condo building's structural components, done by a licensed engineer or architect, that sets full-funding reserve targets for items like roofs, load-bearing walls, and waterproofing. Most condos 3+ stories must have one; costs typically run $2,500 to $10,000+ depending on building size.
What is a reserve study?
A reserve study is a physical inspection plus financial analysis that tells a building's owners how much money they need to set aside now so they can pay for big-ticket repairs and replacements later, without scrambling for a special assessment. A typical reserve study has two parts: a physical component (inspecting the roof, pavement, paint, elevators, and so on, and estimating each item's remaining useful life) and a financial component (calculating how much the association should be contributing to reserves each year to cover those future costs). Outside Florida, reserve studies are usually a financial best practice, sometimes required by state law for HOAs, sometimes just recommended by a management company or CAI (Community Associations Institute). In Florida condos, the concept got a legal teeth transplant after the Champlain Towers South collapse in Surfside in 2021. The legislature responded with SB 4-D (2022) and later SB 154 (2023), creating a new, mandatory subtype of reserve study aimed specifically at structural safety: the Structural Integrity Reserve Study, or SIRS. So "reserve study" is the broad, generic term. "SIRS" is Florida's specific, statutory version that condo and cooperative associations covered by the law must obtain. If you're on a board wading through vendor proposals, you'll see both terms used loosely; know that a generic reserve study bought off the shelf may not satisfy the SIRS requirements in section 718.112(2)(g), Florida Statutes unless the scope matches.
What is a SIRS (structural integrity reserve study) specifically?
A SIRS is a study, performed by a licensed engineer or architect, of specific structural components of a condominium building that is three stories or more in height. Florida Statutes section 718.112(2)(g) defines it as covering "at a minimum," the following components: 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 exceeding $10,000 and that affects the safety of the building's structure [1]. The study must estimate the remaining useful life and the estimated replacement cost or deferred maintenance expense of each component as of the date of the study [1]. That's the engineering side. The financial side then requires the association to set reserve funding for those components at a level that fully funds the estimated cost, no more waiving or underfunding structural items the way older Florida law allowed for general reserves. Who has to do this? Under section 718.103 and 718.112, the SIRS requirement applies to condominium associations that operate a residential condominium of three or more stories in height, including buildings within a larger multi-condominium or mixed-use development in some cases. Two- and one-story condos are generally excluded from the mandatory SIRS, though nothing stops a board from ordering one voluntarily. Cooperatives (co-ops) meeting the same height threshold have a parallel obligation under section 719.106. DBPR, Florida's Division of Condominiums, Timeshares, and Mobile Homes, is the state agency that regulates condo associations and publishes guidance and enforcement information on these requirements [2]. If you want the plain-English regulatory summary rather than the statute text itself, DBPR's condominium association page is the place to check for updates, since the legislature has amended these deadlines more than once since 2022.
When is the SIRS deadline, and does the milestone inspection replace it?
No. The milestone inspection and the SIRS are two different requirements that happen to apply to similar buildings, and boards constantly conflate them. The milestone inspection (section 553.899, Florida Statutes) is a one-time structural inspection at 25 or 30 years of a building's life (25 years if within three miles of the coast, 30 years otherwise), repeated every 10 years after, done by a licensed architect or engineer, and it produces a report on the building's structural condition [3]. The SIRS is a recurring reserve-funding study, not primarily a safety pass/fail inspection. Associations governed by section 718.112 were required to have their initial SIRS completed by December 31, 2024, and turnover-based associations have their own timing tied to control transfer under section 718.301 [1]. After the initial study, the SIRS must be updated at least every 10 years. A milestone inspection can sometimes inform a SIRS (the engineer doing the milestone report may flag structural items that then feed into the SIRS component list), but they're separate deliverables with separate statutory triggers. If your building needs both, expect two contracts, though many engineering firms will bundle scheduling to save a site visit. For background on the inspection side specifically, see our milestone inspection guide and the reserve study fundamentals article.
What is a reserve study for an HOA (as opposed to a condo)?
For a homeowners' association (HOA) in Florida, the term "reserve study" usually refers to the general financial reserve planning process for common-area assets, not the condo-specific SIRS. Florida HOAs are governed by chapter 720, not chapter 718, and chapter 720 does not currently impose the SIRS structural mandate that applies to condos three stories and up. That said, HOAs still often need a reserve study for practical reasons: roads, retention ponds, clubhouse roofs, pool decking, and irrigation systems all wear out, and a board that hasn't budgeted for them ends up either deferring maintenance or hitting owners with a surprise special assessment. Many HOA governing documents require reserve funding on some schedule even without a state structural mandate, so check your declaration and bylaws (and confirm interpretation with association counsel; this article isn't a substitute for that). Our HOA reserve study explainer walks through how HOA boards typically approach component lists, funding methods (straight-line versus pooled/cash-flow), and vendor selection, since the mechanics are similar to condo reserve studies even without the SIRS label attached.
What is an HOA assessment? What are HOA assessments?
An HOA assessment is a fee the association charges owners to fund its operations and obligations, most commonly a recurring "regular assessment" (monthly, quarterly, or annual dues) that pays for landscaping, insurance, management, utilities for common areas, and reserve contributions. A "special assessment" is a separate, usually one-time or limited-duration charge levied when the regular assessment and existing reserves aren't enough, for example after storm damage, a failed roof, or a big structural repair identified by a milestone inspection or SIRS. Under Florida condo law, section 718.116 governs assessments generally, including the association's lien rights if an owner doesn't pay [4]. Special assessments for condos usually require board approval and, depending on the amount and the association's governing documents, sometimes membership notice or a vote; the specific approval threshold lives in your declaration and bylaws, not in a one-size-fits-all statute, so this is genuinely a "read your documents and ask counsel" situation rather than something a general article can verdict for you. For HOAs under chapter 720, similar concepts apply: section 720.303 addresses association powers and financial obligations, including assessment authority [5]. If your board is staring down a large repair bill and debating between a special assessment and a loan, our HOA special assessment guide and condo special assessment insurance overview cover the tradeoffs in more depth.
How much should an HOA or condo have in reserves?
There's no single statutory dollar figure like "$50,000" or "10% of budget" that applies to every association; the honest answer is that the target depends on the size, age, and component inventory of your specific buildings, which is exactly why a professional reserve study exists instead of a rule of thumb. What Florida law does specify, for condos covered by section 718.112, is the funding method: reserves for the SIRS-listed structural components must be funded on a full-funding basis (no more "pooling" underfunded structural line items together at reduced contributions, and no more voting to waive reserves for those specific components) [1]. Non-structural reserve items (things not on the SIRS list) can still, in some cases, be pooled or adjusted depending on board and membership votes, subject to the statute's limits. Industry guidance from the Community Associations Institute and various state reserve-study associations generally recommends associations target funding somewhere between 70% and 100% of the "fully funded" reserve level (the amount that would exist if every component's reserve had been contributed to on schedule since installation), with anything much below 30% flagged as a red zone risking special assessments. Since Florida's SIRS-covered structural items are now legally required to be fully funded, boards can't simply pick a comfortable percentage for those line items anymore; the study itself sets the target, and the board's job is to fund toward it. For state-level relief options some associations have pursued around funding timelines, see Florida condo reserve fund relief.
How much does a reserve study or SIRS cost?
| Generic HOA reserve study | Small HOA, few structures | $1,000 - $3,000 | |
|---|---|---|---|
| SIRS, first-time | Condo, 20-75 units | $2,500 - $8,000 | |
| SIRS, first-time | Large/high-rise condo | $10,000 - $25,000+ | |
| SIRS, 10-year update | Any size | Often lower than initial study | These ranges are drawn from industry reporting and vendor proposal patterns rather than a single government price schedule; DBPR does not set or cap reserve study fees, so get local quotes to confirm current pricing for your building [2]. |
Costs vary widely by building size, number of components inspected, and whether the study is a first-time SIRS or a 10-year update. Based on typical Florida engineering-firm proposals reported by industry sources and DBPR-adjacent guidance, small to mid-size condo buildings (roughly 20 to 75 units) commonly see SIRS pricing in the range of $2,500 to $8,000, while larger or more complex buildings (high-rises, multiple structures, extensive amenities) can run $10,000 to $25,000 or more. The variables that move the price most: number of buildings/structures on the property, square footage, number of distinct structural components requiring separate estimates, site accessibility (a beachfront tower with limited parking costs more to inspect than a suburban mid-rise), and whether the firm needs to do invasive testing (core samples, moisture probes) versus a purely visual inspection. A generic reserve study without the structural engineering component tends to run cheaper, sometimes $1,000 to $3,000 for smaller HOAs, because it doesn't require a licensed engineer's stamp on structural remaining-useful-life estimates the way a SIRS does. Boards should get at least two or three quotes and confirm the proposal explicitly states it will satisfy section 718.112(2)(g), more than general reserve planning; ask the vendor to cite the statute in the engagement letter. | Study type | Typical building size | Approximate cost range |
Are HOA special assessments tax deductible?
For individual homeowners, special assessments are generally not tax deductible as a straightforward itemized expense, because the IRS treats them like the regular HOA dues they resemble: a payment toward a shared, non-governmental service rather than a deductible tax. The IRS's general position on HOA fees and assessments (covered in guidance on rental and personal-residence expenses) is that they're nondeductible personal expenses for a primary residence, similar to home maintenance costs [6]. There are exceptions worth knowing. If the unit is a rental property, special assessments tied to operating expenses may be deductible as a rental expense in the year paid, subject to normal rules distinguishing repairs from capital improvements. If the assessment funds a capital improvement (a new roof, a structural retrofit) rather than a repair, it typically gets added to your cost basis in the property rather than deducted immediately, which still helps you later by reducing taxable gain on sale. This is genuinely IRS-territory, not condo-law territory, so if a special assessment on your building runs into five or six figures, it's worth a conversation with a CPA rather than guessing. Nothing in Florida's chapter 718 or 720 statutes changes federal tax treatment; state law governs whether the assessment is valid and how it's collected, not whether it's deductible.
What happens if a condo association skips or delays its SIRS?
Associations that don't complete the required SIRS by the statutory deadline face a few practical consequences, though the exact enforcement mechanism has been a moving target as the legislature has amended the law since 2022. DBPR has regulatory authority over condominium associations and can pursue administrative action for statutory violations, and owners or the association itself can face difficulty with things like unit sales, refinancing, and insurance renewal if lenders or title companies ask for proof of SIRS compliance and the board can't produce it [2]. Beyond enforcement, the practical risk is worse: a building that skips its SIRS also skips the structural inspection that would have caught a deteriorating support beam, a failing waterproofing membrane, or corroding rebar before it became a five-figure emergency repair (or worse). The SIRS requirement exists because Champlain Towers South's structural problems were documented years before the collapse and the funding to fix them wasn't there. That's not a hypothetical; it's the specific regulatory history behind this law. Boards that are behind should talk to their association's attorney about current deadlines (these have shifted with amendments like SB 154 in 2023, so confirm current dates with counsel and your county rather than relying on a single article), get engineering quotes moving immediately, and communicate proactively with owners about the timeline. Waiting doesn't reduce the eventual cost; it usually increases it, since deferred structural problems compound.
How does a board actually use a SIRS once it's done?
Once the SIRS report lands on the board's desk, it becomes the backbone of your reserve budget, not a document to file and forget. Section 718.112 requires the association's annual budget to include reserve line items funded at the level the SIRS specifies for covered structural components [1]. That means your next annual meeting, budget mailing, and reserve line items all need to reflect the study's numbers. Practically, a board should: (1) have the engineer or architect walk the board through the findings in plain language, more than hand over a PDF; (2) update the reserve schedule in the annual budget to match required contributions; (3) decide, with counsel's input, whether any near-term structural items need a special assessment versus phased reserve funding; and (4) calendar the 10-year update so this doesn't become a recurring fire drill. This is where a lot of volunteer boards get overwhelmed, not because the engineering is hard to understand but because tracking deadlines (milestone inspection, SIRS update, budget ratification, owner notice requirements) across multiple statutes is a scheduling problem as much as a technical one. That's the specific gap a $199 Board Compliance Kit is built to close: it doesn't replace your engineer or your attorney, but it organizes the deadlines, notice templates, and document checklist so your board isn't reconstructing the compliance calendar from scratch every renewal cycle.
How do I find a qualified SIRS provider?
The SIRS must be performed by a licensed engineer or architect under section 718.112(2)(g); a generic reserve-study consultant without that license can't legally issue the structural component estimates the statute requires. Start by confirming the individual or firm's license status through DBPR's license verification tools, since the Department of Business and Professional Regulation oversees both the condo-association side and, separately, professional engineer and architect licensure in Florida [2]. Get at least two competing proposals and ask each firm to walk through their methodology for remaining-useful-life estimates, more than their price. Ask whether they've done SIRS work for buildings of a similar age, height, and coastal exposure to yours; a firm that mostly does inland single-family inspections may not have deep experience with high-rise waterproofing and rebar corrosion patterns common in coastal towers. Finally, get the engagement letter in writing with an explicit statement that the deliverable will satisfy section 718.112(2)(g)'s minimum component list. Boards have been burned by "reserve studies" that looked thorough but skipped a required component category, forcing a redo.

Frequently asked questions
What is a reserve study?
A reserve study is an inspection and financial analysis that estimates how much money an association needs to set aside to repair or replace major shared components (roofs, paving, structural systems) over their useful lives, so owners aren't hit with surprise special assessments when something wears out.
What is a reserve study for an HOA?
For an HOA, a reserve study is the general financial planning process covering common-area assets like roads, clubhouses, pools, and irrigation. Unlike condo SIRS studies under chapter 718, Florida HOAs (chapter 720) aren't currently subject to a state structural reserve mandate, though governing documents may still require reserve funding.
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 when regular funds and reserves can't cover a specific cost, like storm damage or a major structural repair.
How much should an HOA have in reserves?
There's no universal dollar figure; the right amount depends on your component inventory and a professional reserve study's findings. Industry guidance generally targets 70% to 100% of "fully funded" reserve levels, and Florida condos with SIRS-covered structural items are now statutorily required to fund those at 100%, not a discretionary percentage.
How much does a reserve study cost?
Generic HOA reserve studies often run $1,000 to $3,000 for smaller associations. A Florida SIRS, which requires a licensed engineer or architect, typically costs $2,500 to $8,000 for a mid-size condo and $10,000 to $25,000 or more for large or high-rise buildings, based on typical vendor pricing patterns.
Are HOA special assessments tax deductible?
Generally no, for a personal residence; the IRS treats them like nondeductible personal home expenses. Exceptions exist for rental properties (may be deductible as an operating expense) or when the assessment funds a capital improvement, which usually adds to your cost basis instead of an immediate deduction. Confirm specifics with a CPA.
What is a SIRS in Florida condo law?
SIRS stands for structural integrity reserve study, a study required under section 718.112(2)(g) of Florida Statutes for condo buildings three stories or taller. A licensed engineer or architect inspects structural components (roof, load-bearing walls, foundation, waterproofing, and more) and sets full-funding reserve targets for each.
Is the SIRS the same as the milestone inspection?
No. The milestone inspection (section 553.899) is a one-time structural safety inspection at 25 or 30 years of building age, repeated every 10 years. The SIRS is a recurring reserve-funding study. Many buildings need both, on separate schedules, from separate contracts.
Which buildings must get a SIRS?
Florida condominium associations operating residential buildings three stories or more in height generally must complete a SIRS under section 718.112, with parallel requirements for cooperatives under chapter 719. Two-story and shorter condos are typically outside the mandatory requirement, though they can order one voluntarily.
What happens if my association misses the SIRS deadline?
Consequences can include DBPR regulatory action, complications with unit sales or refinancing if lenders require proof of compliance, and, more importantly, missing the structural inspection that could catch a dangerous deterioration early. Deadlines have shifted with legislative amendments, so confirm current dates with your association's counsel.
Can reserves for SIRS items still be waived or pooled by owner vote?
For components covered by the SIRS list, no; section 718.112 removed the option to waive or underfund those specific structural reserve items, requiring full funding instead. Non-SIRS reserve items may still be subject to different, less restrictive funding rules depending on board and membership votes.
Does a SIRS replace my association's older reserve study?
Not automatically. If your association already had a general reserve study, the SIRS adds a structural-engineering layer specific to the components section 718.112 requires. Many associations end up maintaining both a broader reserve schedule and the SIRS-specific structural funding requirements side by side.
