TL;DR
SIRS (Structural Integrity Reserve Study) is a Florida-required inspection of a condo building's structural and safety components, used to set mandatory reserve funding under Florida Statutes 718.112. Buildings 3+ stories must complete one, generally by December 31, 2024 for existing associations, then every 10 years. It replaces guesswork with an engineer's cost and timeline estimate for each component.
What is SIRS in real estate?
SIRS stands for Structural Integrity Reserve Study. In Florida real estate, it's a formal study of a condominium building's structural components, done by a licensed engineer or architect, that produces a funding schedule for repairing or replacing those components before they fail. It is not the same as a home inspection and it's not optional for most Florida condos. The requirement comes from Florida Statutes 718.112(2)(g), enacted after the 2021 Surfside collapse killed 98 people. The law says a SIRS must "at a minimum" evaluate the roof, load-bearing walls, 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... as determined by the licensed engineer or architect performing the visual inspection" [1]. The practical effect: a SIRS tells the board how much money it needs to set aside, every year, for the next 30-plus years, broken out component by component. It's the technical backbone behind reserve study requirements for condo boards statewide.
Which buildings need a SIRS and by when?
Florida requires a SIRS for condominium buildings that are three stories or more in height, based on the total number of habitable stories above ground, regardless of whether the association calls itself a high-rise. Timeshares are excluded [1]. Existing associations needed their first SIRS completed by December 31, 2024. New buildings must get one done within the same general framework tied to their milestone inspection timeline: 25 years from certificate of occupancy for coastal buildings (within three miles of the coastline), 30 years for others, then every 10 years after [2]. Boards that missed the 2024 deadline are not automatically off the hook; the requirement doesn't expire, and unmet obligations typically compound with the next milestone inspection cycle. Confirm your building's exact deadline and any local extension with your association's counsel and county building department, since some counties adjust local milestone triggers. The Florida Division of Condominiums, Timeshares, and Mobile Homes under DBPR oversees this area of the statute [3]. If your building already went through, or is scheduled for, a milestone inspection, the SIRS and the milestone report often get scheduled together because the same engineer may perform both, though they are legally distinct deliverables.
What is a reserve study?
A reserve study, in general (more than Florida SIRS), is a long-range financial planning document that identifies an association's major common-area components, estimates their remaining useful life, and projects how much money the association needs to save each year to pay for future repairs and replacements without a surprise bill. A reserve study typically has two parts: a physical analysis (what components exist, their condition, expected life) and a financial analysis (current reserve balance, funding plan, contribution schedule). Most reserve study providers use one of a few funding models, the most common being the "component method" versus the older "pooled" or percent-funded approach. Florida's SIRS is a specific, statutory version of a reserve study, limited to structural and life-safety components and mandated by state law for qualifying condos. A general reserve study can cover everything from pools to parking lot asphalt to elevators, and many associations do both: a SIRS for the structural pieces the law requires, and a broader reserve study for the rest of the property. See our reserve study for condo association guide for how the two fit together.
What is a reserve study for an HOA?
For a homeowners association (as opposed to a condo), a reserve study serves the same core function: figuring out what major common assets exist (roofs on clubhouses, pool equipment, roads, retaining walls, playground structures) and building a savings plan so the HOA isn't forced into a special assessment when something big breaks. Unlike condo SIRS requirements under 718.112, most single-family HOAs in Florida are governed by chapter 720, not 718, and the structural reserve study mandate does not apply to them the same way. HOAs generally are not legally required to have a formal reserve study unless their declaration or bylaws say so, though Florida law does require HOAs to disclose reserve funding status and, if reserves aren't fully funded, to get member approval for the funding level in some circumstances. Many HOA boards choose to commission one anyway because underfunded reserves are the single biggest cause of large, unpopular special assessments. A hoa reserve study is cheap insurance against a five-figure surprise bill.
How much does a reserve study cost?
Costs vary a lot by building size, component count, and whether it's a basic reserve study or a full SIRS requiring an engineer's site visit and stamped report. As a rough range reported across the industry and by Florida engineering firms doing SIRS work, small condo buildings (under 50 units) often see SIRS costs in the $6,000 to $20,000 range, while larger or more complex buildings, especially those with parking garages, seawalls, or extensive concrete restoration needs, can run $20,000 to $60,000 or more. General (non-structural) HOA reserve studies tend to be less expensive, often $2,000 to $8,000, because they don't require the same engineering site inspection depth. There's no statewide fee schedule; DBPR does not set or cap reserve study or SIRS pricing. Get at least two or three quotes from Florida-licensed engineers or architects, and ask specifically whether the quote includes the full statutory component list under 718.112(2)(g) [1], because a cheap quote that skips required components will need to be redone. The study itself is only step one. Boards then have to schedule the funding conversation, notify owners, and update budgets, which is where a lot of boards lose time and miss deadlines simply from paperwork overload rather than any technical failure.
What is an HOA assessment?
An HOA assessment is a fee an association charges its members (owners) to pay for shared expenses. There are two basic types: regular assessments (recurring dues, usually monthly or quarterly, that fund operating costs and reserves) and special assessments (one-time or limited-duration charges levied to cover an unexpected or underfunded cost, like a roof replacement or storm damage repair). Assessments are not optional dues you can skip. Florida Statutes chapter 718 (for condos) and chapter 720 (for HOAs) give associations the legal authority to levy and, if unpaid, place liens on units or lots for unpaid assessments [4]. This is one reason boards take reserve planning seriously: a well-funded reserve, informed by a solid SIRS or reserve study, reduces the odds of a large special assessment landing on owners with little warning.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure or universal percentage that Florida law mandates for how much an association should have in reserves overall; the requirement instead focuses on funding each component according to its SIRS-based schedule. For condos subject to 718.112, the statute requires that reserves for the SIRS-covered components be funded based on the study's projected costs, and importantly, associations can no longer vote to waive or reduce SIRS reserve funding for those structural items, a change that took effect for study cycles after the 2024 deadline [1]. A commonly cited industry rule of thumb (not a legal standard) is that a healthy reserve fund should be at least 70% funded relative to the ideal balance for the association's age and component mix; anything under roughly 30% funded is considered a red flag by many reserve professionals and lenders, including secondary mortgage market guidelines that scrutinize HOA reserve health during loan underwriting. Freddie Mac, for instance, reviews an association's budget and reserve allocations as part of its condominium project review requirements, though it does not publish a single universal percent-funded threshold applicable to every project [5]. The honest answer for a Florida condo board: the number you need isn't a general percentage, it's the specific dollar figure your SIRS produces for your building's roof, structure, waterproofing, and other listed components. That figure is legally binding for reserve funding purposes once the study is done and adopted.
What are HOA assessments used for, and are special assessments tax deductible?
Regular assessments typically cover landscaping, insurance, management fees, utilities for common areas, and contributions to reserves. Special assessments usually cover a specific, often unbudgeted cost: a new roof, storm damage not fully covered by insurance, a required structural repair identified in a milestone inspection or SIRS, or litigation costs. On taxes: for most owners who use the unit as a personal residence, HOA and condo assessments, including special assessments, are generally not tax deductible, the same way regular HOA dues aren't deductible for a primary residence, according to IRS guidance on nondeductible personal expenses [6]. There are exceptions. If the unit is a rental property or used for business, a portion of assessments (including a special assessment tied to repairs, though not necessarily capital improvements, which may instead need to be depreciated) can potentially be deducted as a business expense. Capital improvement type special assessments (like a full roof replacement) are often added to the property's cost basis rather than deducted outright, even for rental property. This is a tax question specific to your ownership structure and use of the unit, so this isn't tax advice: talk to a CPA familiar with real estate before assuming any assessment is deductible. For board-level financial protection, some associations also carry condo special assessment insurance or loss-assessment coverage riders that can reimburse owners for a portion of a special assessment tied to a covered peril, though these have limits and exclusions worth reading carefully.
What happens if a board skips or delays its SIRS?
Skipping or delaying a required SIRS puts a board in a legally exposed position. Florida law requires associations to complete the study, and failing to do so can affect insurance renewals, unit resale (buyers and lenders increasingly ask for milestone and SIRS documentation before closing), and, in cases of clear board negligence, personal exposure for board members if a preventable structural failure occurs. There's also a practical cost to delay. The longer a board waits, the more likely deferred components have deteriorated further, which usually means a bigger number on the eventual repair bill and a harder special assessment conversation with owners who feel blindsided. Some buildings received short-term relief. The Florida legislature passed adjustments in 2024 (through SB 1103) giving some associations limited flexibility on timing and disclosure requirements [7]; see our breakdown of florida condo reserve fund relief for what changed and what didn't. None of that relief eliminates the underlying SIRS requirement for buildings that qualify; it mostly adjusts deadlines, disclosure formats, and, in narrow cases, funding timelines.
How does SIRS connect to the milestone inspection?
The milestone inspection and the SIRS are separate legal requirements that often get scheduled together because they look at overlapping structural systems. The milestone inspection (F.S. 553.899) is a phase one, and if needed phase two, structural inspection focused on safety, due at 25 years (coastal) or 30 years (inland) from certificate of occupancy, then every 10 years [2]. The SIRS, under 718.112, is specifically about reserve funding for those same types of components. A board can, and often should, hire the same engineering firm to do both inspections in one site visit, saving on mobilization costs and giving the board a single coordinated set of findings. But don't assume one report substitutes for the other legally; check with your association's counsel about whether your engineer's scope of work explicitly satisfies both statutes, because a report written only for milestone purposes may not include every SIRS-required component.
How a board actually uses a SIRS once it's done
Getting the SIRS report is the easy part. The harder part is turning a 40-page engineering document into a budget, a member notice, a reserve line-item schedule, and (if needed) a special assessment vote, all on statutory deadlines that don't care whether your board is run by volunteers with day jobs. This is the gap that trips up a lot of self-managed and lightly-managed associations. Boards know they need a SIRS. They get one. Then it sits in a drive somewhere because nobody built the calendar of what comes next: annual reserve contribution updates, member disclosure statements, insurance renewal documentation, and the next 10-year study date. A $199 one-time Building-Specific Board Compliance Kit exists for exactly this gap: it organizes your SIRS and milestone deadlines, reserve contribution schedule, and required owner disclosures into one calendar built around your building's actual age, height, and coastal location, so the board isn't relying on memory or a spreadsheet someone built in 2022 and forgot to update. It doesn't replace your engineer, your CPA, or your attorney; it organizes what they give you.
Frequently asked questions
What is SIRS in real estate, in one sentence?
SIRS (Structural Integrity Reserve Study) is a Florida-mandated engineering study of a condo building's structural and life-safety components, used to set legally binding reserve funding levels under Florida Statutes 718.112, required for qualifying buildings three stories or taller.
What is a reserve study?
A reserve study is a long-range plan that identifies an association's major shared components (roofs, structure, pools, roads, elevators), estimates their remaining life, and calculates annual savings needed so the association can pay for future repairs without a sudden special assessment.
What is a reserve study for an HOA?
For an HOA, a reserve study assesses common-area assets like clubhouses, pool equipment, roads, and amenities, then builds a funding schedule. Unlike condo SIRS under chapter 718, most Florida HOAs aren't legally required to do one unless their governing documents require it, though many do it voluntarily to avoid surprise special assessments.
How much should an HOA have in reserves?
There's no single Florida-mandated percentage for HOA reserves generally. Industry professionals often use 70% funded as a healthy benchmark and under roughly 30% funded as a warning sign, but the only legally binding figure for condos is the specific dollar amount produced by the building's SIRS for statutory components.
How much does a reserve study cost?
Costs vary by building size and scope. Full Florida SIRS reports often run $6,000 to $20,000 for smaller buildings and $20,000 to $60,000-plus for larger or more complex ones. General, non-structural HOA reserve studies are usually cheaper, often $2,000 to $8,000, since they skip the engineer-level structural inspection.
What is an HOA assessment?
An HOA assessment is a fee charged to owners to cover shared costs. Regular assessments are recurring dues for operations and reserves; special assessments are one-time charges for unexpected or underfunded costs like a roof replacement, storm repair, or a structural fix identified by a milestone inspection or SIRS.
Are HOA special assessments tax deductible?
Generally no, for a personal residence, similar to regular HOA dues, per IRS rules on nondeductible personal expenses. Exceptions can apply if the unit is a rental or business property, where a portion may be deductible as a business expense or added to cost basis if it's a capital improvement. Ask a CPA about your specific situation.
Who has to get a SIRS in Florida?
Condominium associations with buildings three stories or more in height (excluding timeshares) must complete a SIRS under Florida Statutes 718.112(2)(g). Existing qualifying associations generally needed one completed by December 31, 2024, then must repeat the study every 10 years.
What does a SIRS actually inspect?
At minimum, Florida law requires SIRS to cover the roof, load-bearing walls, primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, windows, and any other component with a deferred maintenance or replacement cost over $10,000 that affects those listed items, per F.S. 718.112(2)(g).
Can a condo board waive SIRS reserve funding?
No, not for the structural components covered by the study. Florida Statutes 718.112 removed the ability for associations to vote to waive or underfund reserves for SIRS-required components once the study cycle applies, unlike older rules that allowed broader reserve waivers by member vote.
Is a SIRS the same as a milestone inspection?
No. They are separate legal requirements under different statutes (SIRS under 718.112, milestone inspection under 553.899) though they often overlap in scope and get scheduled with the same engineering firm. A milestone report focuses on structural safety; a SIRS focuses on reserve funding for those same types of components.
What happens if a Florida condo association skips its required SIRS?
The association remains legally required to complete it; skipping doesn't remove the obligation. Consequences can include insurance and financing complications for owners, closing delays for buyers, disclosure problems, and potential liability exposure for board members if a preventable structural issue later occurs. Confirm specific consequences with your association's attorney.
