TL;DR
Florida's Structural Integrity Reserve Study (SIRS) law requires condo and cooperative buildings 3+ stories to get a licensed engineer or architect's reserve study covering key structural components, then fund full (non-waivable) reserves for those items. Most buildings needed their first SIRS by December 31, 2024, tied to their milestone inspection deadline. Confirm your building's exact due date with counsel.
What is a SIRS in Florida condo law?
A Structural Integrity Reserve Study, or SIRS, is a inspection-based reserve study required under Florida Statutes section 718.112(2)(g) for condominium buildings that are three stories or more in height. It's not the same as a general reserve study your board might have done voluntarily for years. A SIRS has to be performed, or at minimum have the visual inspection portion performed, by a licensed engineer or architect, and it has to look at specific structural and life-safety components rather than the whole punch list of association assets. The statute defines what must be 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 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 components listed... as determined by the licensed engineer or architect performing the visual inspection" [1]. That last catch-all matters. It means the inspector, not the board, decides what else belongs on the list. The law was born out of the Champlain Towers South collapse in Surfside in June 2021, which killed 98 people. The Florida Legislature responded with SB 4-D in 2022 and follow-up cleanup legislation in SB 154 (2023), creating both the milestone inspection requirement and the SIRS/reserve funding requirement in the same bill package [2]. If you want the fuller inspection-side explanation, see milestone inspections resources, but SIRS is really the reserve-funding half of the same reform.
Which buildings have to do a SIRS?
The SIRS requirement applies to condominium associations with buildings that are three stories or more in height, regardless of how close they are to the coast. Unlike the milestone inspection law, which has a coastal-versus-inland split affecting the trigger age (25 years near the coast, 30 years inland), the SIRS requirement doesn't hinge on coastline at all. Height is the trigger, not location or age. A few carve-outs exist. Buildings with fewer than three habitable stories don't need a SIRS. Single-family, townhome, and duplex-style structures without shared load-bearing structural elements above two stories generally fall outside it, though associations should confirm classification with counsel rather than guess. Cooperatives are covered too: Florida Statutes 719.106 applies the same SIRS mechanics to residential cooperative buildings meeting the height threshold [3]. HOAs governing single-family homes are not subject to SIRS. The law lives in Chapter 718 (condominiums) and Chapter 719 (cooperatives), not Chapter 720 (homeowners' associations). If your community is a true HOA with detached houses, SIRS doesn't apply, though your board may still want a voluntary reserve study for planning purposes.
When is the SIRS deadline in Florida?
For most existing associations, the first SIRS was due December 31, 2024. That deadline tracks the original SB 4-D and SB 154 language, which required associations to complete a SIRS for each building on or before that date and then submit the completed study to the Division of Florida Condominiums, Timeshares, and Mobile Homes [1][4]. After the first study, SIRS has to be redone at least every 10 years. Some associations pushed hard for another delay in the 2024 and 2025 legislative sessions. Lawmakers did grant limited relief through 2024's SB 1021 and related bills, mostly around funding phase-in and structural integrity reserve line items rather than pushing the study deadline itself back for everyone. Rules have moved more than once since 2022, so don't rely on a blog post (including this one) as the final word. Check the current statute text on flsenate.gov and talk to your association's attorney about your building's actual due date, because grace periods and delayed-developer-turnover buildings can shift the calendar [5]. Newly formed associations and buildings that just turned over from developer control have their own countdown, generally tied to turnover date rather than the 2024 date. If your building turned over in 2023 or later, don't assume the December 2024 deadline applies to you at all.
What is a reserve study?
A reserve study is a professional assessment of a community's major shared components (roofs, pavement, pools, elevators, structural elements) that estimates each item's remaining useful life and the cost to repair or replace it. The study translates those estimates into a recommended annual reserve contribution so the association isn't blindsided by a six-figure repair bill with no savings to cover it. A standard, non-SIRS reserve study typically has two parts: a physical analysis (site visits, component inventory, condition assessment) and a financial analysis (funding plan, either "full funding," "threshold funding," or "baseline funding" models). Florida's Chapter 718 also has a longstanding general reserve requirement separate from SIRS, requiring reserves for roof replacement, building painting, pavement resurfacing, and "any other item that has a deferred maintenance expense or replacement cost exceeding $10,000" once an association turns over from developer control [1]. A SIRS is a specific, statutorily defined subtype of reserve study, narrower in scope (structural and life-safety components only) but with stricter rules: it must be inspection-based, engineer- or architect-led, and its reserves cannot be waived or reduced by a membership vote the way general reserves once could be. For a broader walkthrough of the reserve study process itself, see reserve study and reserve study for condo association.
What is a reserve study for an HOA, and does it differ from a condo SIRS?
For a homeowners' association, a reserve study serves the same basic purpose: figure out what the shared components (clubhouse roof, pool deck, private roads, gate systems) will cost to replace and when, then set aside money gradually instead of hitting owners with a surprise bill. But Florida's SIRS mandate under Chapter 718 doesn't apply to HOAs at all. It's a condo- and co-op-specific statute. Most Florida HOAs are not legally required to commission a reserve study, though many do it voluntarily, and some governing documents (declarations, bylaws) independently require one. Florida Statutes 720.303(6) addresses HOA reserves but leaves funding as largely optional unless the declaration says otherwise or the membership votes to fund reserves fully [6]. That's a meaningfully lighter obligation than what condo boards now face post-Surfside. If you're on an HOA board and unsure whether your documents require a reserve study, that's a question for the association's attorney, not a statute lookup, since the requirement (if any) usually sits in the declaration rather than state law. See hoa reserve study for more detail on the voluntary-versus-mandatory distinction.
What is an HOA assessment, and how is it different from a special assessment?
An HOA assessment (sometimes called a regular or annual assessment) is the routine fee every owner pays, usually monthly or quarterly, to cover operating expenses and reserve contributions. It's budgeted in advance, disclosed to owners, and collected like a subscription. Chapter 720 and Chapter 718 both give associations lien rights if an owner doesn't pay regular assessments. A special assessment is different: it's an extra, often one-time or short-term charge levied outside the normal budget cycle, usually because reserves fell short of an actual repair cost, or because a SIRS-driven or milestone-driven repair came in higher than expected. Boards typically have to follow notice and, in many cases, membership approval procedures set out in the declaration and bylaws before levying one, and the exact threshold and vote requirement varies by association, so check your governing documents rather than assume a state-mandated formula. Post-Surfside reforms have made special assessments more common, not less, in condo buildings that deferred structural reserves for years and now have to catch up. For a deeper look at how special assessments get triggered and what a board's notice obligations typically look like, see hoa special assessment.
How much should a Florida condo or HOA have in reserves?
There's no single statewide dollar figure, and anyone who gives you one number is oversimplifying. The honest answer is: enough to fully fund the replacement cost, on schedule, of every reserve component identified in your study, which will be wildly different for a 12-unit three-story building versus a 400-unit high-rise. What Florida law does say, post-SB 4-D, is that condo associations covered by SIRS can no longer vote to waive or underfund reserves for the structural components on that list. Before the 2022 reforms, owners could vote annually to waive reserve funding entirely or fund it at less than 100%. That option is gone for SIRS components as of the 2024/2025 funding requirement phase-in [1][2]. Non-SIRS reserve items (things like clubhouse furniture or a pool deck resurface not tied to structural safety) may still be subject to different waiver rules depending on current statute language, so confirm with counsel. As a planning benchmark, industry reserve specialists (Community Associations Institute, state-licensed reserve preparers) generally recommend funding to at least 70% of the "fully funded" target as a minimum health threshold, with 100% as the ideal. Associations sitting below roughly 30% funded are considered high-risk for a special assessment within a few years, based on the funding-percentage benchmarks CAI and reserve professionals commonly cite in reserve study guidance. There isn't one federal or state-published number for "how much should reserves be," because it depends entirely on your components, their age, and local replacement costs.
How much does a reserve study or SIRS cost?
Cost depends heavily on building size, number of components, and whether it's a first-time SIRS or a routine 10-year update. Based on ranges commonly reported by Florida engineering and reserve-study firms and referenced in state legislative analysis during the 2022-2023 SIRS rulemaking debates, small associations (under 50 units) often see SIRS costs in the roughly $3,000 to $10,000 range, while larger high-rises with more structural complexity, multiple buildings, or difficult access can run well into the $20,000 to $50,000+ range. These are industry-reported ranges, not a statutory fee schedule; get multiple quotes from Florida-licensed engineers or architects rather than budgeting off a blog estimate. A few cost drivers to know before you request bids: - Number of buildings and total square footage under study
- Whether the milestone inspection and SIRS are bundled with the same engineering firm (often cheaper than hiring separately)
- Age and accessibility of structural components (parking garages and below-grade waterproofing add cost)
- Whether it's a first SIRS (more discovery work) versus a 10-year update (often faster, using prior data as a baseline) The study itself is a separate cost from the reserve contributions it recommends funding. Boards sometimes conflate the two: the $10,000 you pay an engineer for the SIRS report is a one-time professional fee; the reserve contributions the report tells you to save are an ongoing budget line, often much larger.
Are HOA and condo special assessments tax deductible?
Generally, no, not for the individual owner's personal income taxes, in most typical scenarios. Special assessments for repairs, reserve catch-up funding, or capital improvements to common elements are treated by the IRS similarly to home improvement costs: they're usually not currently deductible as an itemized expense for an owner-occupied residence. Owners typically add the assessment to their cost basis in the property instead, which can reduce capital gains tax when they eventually sell. There are exceptions worth knowing. If the unit is a rental property, special assessments tied to repairs (not capital improvements) may be deductible as a rental business expense in the year paid, per general IRS rules on rental property expenses under Publication 527 guidance [7]. Assessments for capital improvements on a rental property are typically depreciated over time rather than deducted all at once. And if a portion of a special assessment is specifically earmarked for a federally declared disaster-related casualty loss, different casualty loss rules under IRS guidance may apply. This is genuinely a case-by-case tax question. Nothing here is tax advice, and owners should talk to a CPA about their specific situation, especially with SIRS-driven special assessments getting larger and more common across Florida condo buildings since 2022.
What happens if a board misses the SIRS deadline?
Associations that fail to complete a required SIRS can face enforcement action from the Division of Florida Condominiums, Timeshares, and Mobile Homes under DBPR, including administrative fines, and the failure can also expose board members to complaints from owners alleging breach of statutory duty. The statute requires the completed SIRS (or, in the interim, evidence of a signed contract for the study) be submitted to the division and made available to unit owners [1][4]. Beyond regulatory risk, there's a practical risk: lenders and title companies increasingly ask for SIRS and milestone inspection status before closing on a unit sale or approving a mortgage in a condo building. Buildings that can't show a current SIRS or milestone report can see financing dry up for buyers, which depresses resale values across the whole association, more than for one seller. If your board is behind, the fix isn't panic, it's sequencing: get a signed engagement letter with a licensed engineer or architect on file immediately (that alone often satisfies interim compliance evidence), get a real completion date, and communicate the timeline to owners in writing. Boards juggling milestone inspections, SIRS, insurance renewals, and annual meeting deadlines all in the same year often lose track of which document is due when. That's the specific problem a $199 Board Compliance Kit is built to organize: a single, building-specific calendar of statutory deadlines with the underlying inspection and reserve study work still done by the licensed professionals the statute requires.
How does SIRS relate to the milestone inspection?
They're related but legally distinct requirements, both created in the same 2022-2023 legislative package. The milestone inspection under Florida Statutes 553.899 is a one-time structural safety inspection performed by a licensed engineer or architect, due at 25 years of building age for coastal buildings (measured from certificate of occupancy) or 30 years for inland buildings, then repeated every 10 years after [8]. It answers the question: is the building structurally sound right now? The SIRS answers a different question: are we saving enough money to maintain and eventually replace the components that keep it sound? A SIRS often draws on milestone inspection findings but is a separate report with its own due date, its own licensed-professional requirement, and its own filing obligation to the Division. Many Florida engineering firms now offer combined milestone-plus-SIRS engagements since the site visit and component review overlap substantially, which can save associations real money versus hiring two firms separately. If your building is approaching both deadlines around the same time, ask prospective engineers directly whether they can scope both reports in one visit.
Frequently asked questions
What is a reserve study?
A reserve study is a professional evaluation of a community's shared components (roofs, elevators, structural elements, pools) that estimates remaining useful life and replacement cost, then recommends an annual funding plan. In Florida condos, a SIRS is a specific, engineer-led version of a reserve study required by statute for structural and life-safety components.
What is a reserve study for an HOA?
For an HOA, a reserve study evaluates shared assets like clubhouses, pools, roads, and gates to plan long-term funding. Unlike Florida condo SIRS requirements under Chapter 718, HOAs under Chapter 720 generally aren't statutorily required to do one unless their governing documents say otherwise, so check your declaration.
What is an HOA assessment?
An HOA assessment is the regular fee (usually monthly or quarterly) owners pay to fund operating expenses and reserves, set through the association's annual budget. It's distinct from a special assessment, which is an extra, often one-time charge levied outside the normal budget cycle to cover an unexpected or underfunded cost.
How much should an HOA or condo have in reserves?
There's no single statewide dollar figure. The target is full funding of every component identified in your reserve study or SIRS, based on its age and replacement cost. Reserve professionals commonly treat 70% of the fully-funded target as a minimum health benchmark and under roughly 30% as high special-assessment risk.
How much does a reserve study or SIRS cost in Florida?
Costs vary by building size and complexity. Industry-reported ranges put small association SIRS reports around $3,000 to $10,000, and large, complex high-rises at $20,000 to $50,000 or more. Get multiple quotes from Florida-licensed engineers or architects; there's no fixed statutory fee schedule.
Are HOA or condo special assessments tax deductible?
Generally not for a personal residence; most special assessments for repairs or capital improvements add to your cost basis instead of being currently deductible. Rental property owners may be able to deduct repair-related assessments as a business expense under IRS rental property rules. Always confirm with a CPA.
Which Florida buildings need a SIRS?
Condominium and cooperative buildings three stories or more in height need a Structural Integrity Reserve Study under Florida Statutes 718.112(2)(g) and 719.106. Height triggers the requirement regardless of coastal proximity or age. Single-family HOAs under Chapter 720 are not covered.
When was the first Florida SIRS deadline?
For most existing qualifying associations, the first SIRS was due December 31, 2024, per the SB 4-D and SB 154 legislative package passed after the 2021 Surfside collapse. Newly turned-over associations may have different deadlines tied to their turnover date, so confirm specifics with counsel.
Can a condo association still waive SIRS reserve funding?
No. Since the post-Surfside reforms, associations covered by SIRS can no longer vote to waive or underfund reserves for the structural components identified in the study. This removed an option that previously let owners vote annually for reduced or zero reserve funding.
Who can legally perform a Florida SIRS?
The visual inspection portion of a SIRS must be performed by a person authorized to practice engineering or architecture under Florida law (a licensed engineer or architect). Boards should verify licensure through the Florida DBPR before signing an engagement contract.
What's the difference between a milestone inspection and a SIRS?
A milestone inspection (Florida Statutes 553.899) is a structural safety check at 25 or 30 years of building age, repeated every 10 years. A SIRS is a separate, statutorily required reserve funding study covering structural components, redone at least every 10 years, with its own filing obligation to the Division.
What happens if a board doesn't complete its SIRS on time?
The association can face enforcement action from Florida's Division of Condominiums, Timeshares, and Mobile Homes, including fines, and may see financing and resale problems as lenders increasingly ask for SIRS status before closing. Getting a signed engagement letter with a licensed engineer immediately helps limit exposure.
Does a Florida SIRS have to include every building component?
No. It covers a defined list: roof, structural members, floor, foundation, fireproofing/fire protection, plumbing, electrical, waterproofing/exterior painting, windows and exterior doors, plus any other item over $10,000 in cost that the inspecting engineer or architect determines affects those listed components.
