TL;DR
A structural integrity reserve study (SIRS) is a Florida-mandated inspection of a condo building's structural components, done by a licensed engineer or architect, that sets fully-funded reserve amounts for roofs, roads, load-bearing walls, and more. Stuart buildings 3+ stories had to complete their first SIRS by December 31, 2024, per Fla. Stat. 718.112.
What is a reserve study?
A reserve study is a financial and physical assessment of a building's major components, roofs, elevators, pavement, plumbing, painting, and structural elements, that estimates how much money an association needs to save each year to pay for replacing those items without a surprise bill. A good reserve study has two halves: a physical inspection (what condition is the roof in, how many years does it have left) and a funding plan (how much to collect monthly so the money is there when the roof needs replacing). In Florida, there are actually two related but distinct things people mean by "reserve study" for condos. The general reserve schedule under Fla. Stat. 718.112(2)(f) covers routine components like roof, painting, and pavement. The structural integrity reserve study (SIRS), added by SB 4-D after the Surfside collapse, is narrower and deeper: it's specifically about structural safety items, and it's mandatory for condo and cooperative buildings three stories or higher [1]. For a Stuart association sitting near the Intracoastal or on a barrier island, this isn't an academic distinction. Salt air accelerates corrosion of rebar and metal railings, and Martin County's humidity and storm exposure shorten the useful life of roofing and waterproofing compared to inland Florida. A reserve study done by someone who understands coastal wear patterns matters more here than in, say, Ocala.
What is a structural integrity reserve study (SIRS) for an HOA or condo?
A SIRS is a mandatory, engineer-or-architect-prepared inspection and funding schedule required for Florida condominium buildings three stories or more in height. It covers a specific statutory list of structural components and forces the association to reserve fully for each one, no more waiving structural reserves at the annual meeting [1]. Under Fla. Stat. 718.112(2)(g), the SIRS must address at minimum: 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 items listed" [1]. The statute is explicit that this is a completely different animal from a routine reserve schedule: "the study performed under this subparagraph must, at a minimum, identify the estimated remaining useful life and the estimated replacement cost or deferred maintenance expense of the required reserve fund components," and it must be based on a "visual inspection" performed by a licensed engineer or architect [1]. It's worth being blunt here: this law applies specifically to condominiums and cooperatives under chapter 718 and 719. A standalone single-family HOA (chapter 720) generally does not have a SIRS obligation, though HOAs still have their own reserve and disclosure rules. If your Stuart property is a townhome HOA rather than a condo, check with counsel before assuming SIRS applies. See our broader reserve study explainer for the full 718 vs 720 breakdown.
Who is required to get a SIRS in Martin County / Stuart, and by when?
Any condominium association with a building three stories or higher, regardless of county, had to complete its first SIRS by December 31, 2024, and then every 10 years after that [1] [1]. Stuart and the rest of Martin County follow the same statewide deadline; there's no local extension or carve-out for coastal towns. The milestone inspection (the separate structural safety inspection under Fla. Stat. 553.899) has its own age-based trigger: buildings must get their first milestone inspection by the 30th anniversary of the certificate of occupancy, or the 25th anniversary if the building is within three miles of the coast [2]. Because Stuart sits directly on the St. Lucie River and close to the Atlantic, a lot of buildings there fall into the 25-year coastal trigger rather than the 30-year standard one. Check your building's CO date with the Martin County Building Division to know which clock applies to you. DBPR, the Florida Department of Business and Professional Regulation, is the state agency that oversees condominium associations and enforces these reserve and inspection requirements [3]. If your board is unsure whether a specific building qualifies, DBPR's condominium division and your association's own counsel are the two places to get a real answer, not a message board.
How much does a SIRS or reserve study cost in Florida?
Costs vary widely by building size, number of components, and region, but industry reporting and reserve-study firms commonly cite figures in the range of roughly $3,000 to $20,000+ for a SIRS, with larger high-rises and buildings with more complex structural systems landing at the higher end. A basic non-structural reserve schedule for a small low-rise is usually cheaper than a full SIRS for a coastal high-rise with a parking garage, pool deck, and seawall. A few things drive the price up specifically for Stuart-area buildings: buildings on the barrier islands (Hutchinson Island area) often need marine/waterfront-specific structural review, seawalls and dock structures add scope, and any building with a known corrosion or spalling issue may need supplemental testing (concrete coring, chloride testing) beyond the baseline visual inspection. Get at least two or three quotes from licensed engineers or architects who specifically do SIRS work, not general home inspectors. Ask what's included: is it just the visual inspection, or does the fee also include the funding schedule and the board presentation? Some firms bundle these, some charge separately, and a $4,000 quote that doesn't include the funding analysis isn't actually cheaper than a $6,000 quote that does.
What is an HOA assessment, and how does it relate to reserves?
An HOA or condo assessment is a fee the association charges owners, on top of regular dues, to cover a shortfall, an emergency repair, or a major project the reserve fund can't fully cover. Regular assessments are the predictable monthly or quarterly dues; special assessments are the one-time or short-term charges levied when reserves fall short or an unexpected cost hits (a burst pipe, storm damage, a structural repair flagged by the SIRS). The whole point of a well-funded reserve study is to make special assessments rarer and smaller. If a board has been collecting adequately for 20 years toward a roof replacement, the roof failing doesn't require a $15,000-per-unit emergency assessment; it requires writing a check from money that's already there. Boards that waived or underfunded reserves for years, which used to be legal under a simple majority owner vote before SB 4-D, are the ones now facing painful special assessments to catch up. As of the SIRS reforms, associations can no longer vote to waive or reduce reserve funding for the structural components covered by the SIRS list [1]. That's a real change: pre-2022, plenty of Florida condo boards kept dues artificially low by voting down full reserve funding year after year, then got hit with exactly the kind of special assessment the law was designed to prevent. See our hoa special assessment piece for how assessments get calculated and noticed to owners.
How much should an HOA or condo have in reserves?
The honest answer is: enough to fully fund the remaining useful life of every major component, calculated component by component, not a flat percentage or round number. For SIRS-covered structural items, Florida law now requires full funding with no waiver option [1]. For everything else (routine reserve items under 718.112(2)(f)), owners can still vote to underfund, though doing so is generally a bad idea financially. A rough industry rule of thumb some reserve specialists use is that reserves should be funded to at least 70% of the "fully funded" ideal to avoid special assessment risk, though this isn't a statutory requirement, it's a practitioner benchmark, and boards should treat it as a floor, not a target. There's no single federal or state standard percentage that applies to every building; a 15-year-old low-rise with a new roof needs a very different reserve balance than a 45-year-old high-rise on the water. The practical way boards figure this out is by having a licensed reserve specialist or engineer run the actual numbers: replacement cost of each item, remaining useful life, and current reserve balance. That output, not a rule of thumb, is what should drive your monthly assessment. Our hoa reserve study guide walks through how that funding schedule gets built line by line.
Are HOA and condo special assessments tax deductible?
Generally, no, special assessments paid to your own HOA or condo association for repairs, reserves, or capital improvements are not deductible on your personal federal income tax return if the unit is your primary residence, because the IRS treats them like other nondeductible homeowner costs (similar to regular HOA dues). The IRS does not have a specific line for HOA special assessments as a personal deduction [4]. There are exceptions worth knowing. If you own the unit as a rental or investment property, special assessments for repairs and maintenance are often deductible as a business expense in the year paid, and assessments for capital improvements may need to be depreciated over time rather than deducted immediately, similar to how the IRS treats capital improvements on any rental property [4] [5]. If you use part of your primary residence for a home office, a portion may be deductible too. This is genuinely a case where you should talk to a CPA, not a board member or a blog. The tax treatment depends on how you use the unit and how the assessment is classified (repair vs. capital improvement), and getting it wrong on a return isn't worth guessing about.
What does a SIRS report actually look like, and what should a board do with it?
A completed SIRS report should give the board, for each covered component: current condition, estimated remaining useful life, and estimated cost to repair or replace, plus a recommended annual reserve contribution to fund it fully by the time it needs work [1]. Associations must provide a copy or summary to unit owners and, per statute, associations completing a SIRS after December 31, 2024 must comply with the funding requirements starting with the fiscal year following delivery of the study [1] [1]. Once the report lands, the board's job is to turn engineering findings into a budget and a communication plan: update the reserve line items in next year's budget, notify owners of any resulting assessment increase, and keep the report on file for the next required update (every 10 years, or sooner if a milestone inspection turns up something new). This is where a lot of volunteer boards get stuck, not because the engineering is hard to understand, but because organizing which deadline applies to which component, and documenting that you did it, eats a weekend every quarter. That's the specific gap our $199 Building-Specific Board Compliance Kit is built for at /board-kit-builder: it doesn't replace the engineer's inspection or the reserve specialist's funding math, but it organizes the resulting deadlines, tracks what's been delivered to owners, and keeps a paper trail a board can hand to new members or an attorney without redoing the research. The kit doesn't determine whether the building meets the statute; only a licensed engineer and your association's counsel can make that call.
What's the difference between a milestone inspection and a SIRS?
A milestone inspection is a one-time structural safety check required by Fla. Stat. 553.899 for buildings three stories or higher, triggered by age (25 years for coastal buildings, 30 years inland, then every 10 years after) [2]. A SIRS is the ongoing reserve-funding study required by Fla. Stat. 718.112 specifically for condos and co-ops, done every 10 years regardless of age, and its job is financial planning, not a pass/fail safety verdict [1]. They overlap in subject matter (both look at structural components) but they answer different questions. Milestone inspection asks: is this building structurally sound right now? SIRS asks: how much money do we need saving, and for what, over the next decade? A building can pass its milestone inspection and still have a SIRS that shows underfunded reserves, and vice versa; they're not substitutes for each other, and a board needs both if the building qualifies for both.
What should a Stuart, FL board budget and plan for right now?
If your Martin County condo hasn't completed its first SIRS, that deadline already passed (December 31, 2024) for existing buildings, so the priority is closing the gap fast with a licensed engineer or reserve specialist, not waiting for a future deadline [1] [1]. If you're unsure whether your building's milestone inspection trigger is 25 or 30 years, pull your certificate of occupancy date from Martin County records first; coastal proximity in Stuart makes the 25-year trigger common but not universal [2]. Budget-wise, boards should expect two separate line items going forward: the milestone inspection fee (a few thousand to tens of thousands depending on building size and complexity) and the SIRS/reserve funding contribution (which, again, can no longer be voted down for structural items) [1] [2]. Boards that try to handle both with the same engineer in the same visit sometimes save money, but confirm the scope covers both statutory requirements, more than one. Finally, keep good records. If your association ever faces a lawsuit, an insurance dispute, or a resale where a buyer's lender wants proof of reserve compliance, having the SIRS report, milestone inspection report, and board meeting minutes showing how you acted on them organized and dated is worth more than any single inspection.

Frequently asked questions
What is a reserve study?
A reserve study is an assessment of a building's major components (roof, paving, plumbing, structure) that estimates remaining useful life, replacement cost, and how much money the association should save annually. In Florida condos, structural items now require a specific version called a SIRS under Fla. Stat. 718.112, done by a licensed engineer or architect.
What is a reserve study for an HOA?
For a standard HOA (chapter 720, single-family or townhome communities), a reserve study estimates the cost and timing of replacing shared components like roads, pools, and clubhouses, and recommends a funding schedule. Unlike condo SIRS requirements, most Florida HOAs are not statutorily mandated to complete one, though it's still financially prudent.
What is an HOA assessment?
An HOA assessment is a fee charged to owners to fund association operations and reserves. Regular assessments are routine dues; special assessments are additional one-time or short-term charges when reserves fall short of an unexpected or major expense, like a storm-damaged roof or a structural repair identified in a SIRS.
How much should an HOA have in reserves?
There's no single statewide percentage rule. The financially sound answer is fully funding each component based on its actual replacement cost and remaining life, calculated by a reserve specialist. Some practitioners use 70% of full funding as a rough floor to limit special assessment risk, but that's an industry guideline, not a Florida statute.
How much does a reserve study cost?
A structural integrity reserve study in Florida commonly runs from roughly $3,000 to $20,000 or more, depending on building size, height, and complexity. Coastal buildings with seawalls, docks, or known corrosion issues typically cost more due to added testing and engineering scope.
Are HOA special assessments tax deductible?
Usually not, if the property is your primary residence; the IRS treats them like nondeductible homeowner costs similar to regular dues. If the unit is a rental or investment property, assessments for repairs may be deductible as a business expense, and capital improvement assessments may need to be depreciated. Confirm with a CPA.
When was the SIRS deadline for Florida condos?
Existing condominium and cooperative buildings three stories or higher had to complete their first structural integrity reserve study by December 31, 2024, per Fla. Stat. 718.112(2)(g), and must repeat it every 10 years after that.
Does Stuart, FL use the 25-year or 30-year milestone inspection trigger?
It depends on the building's exact location and certificate of occupancy date. Fla. Stat. 553.899 sets a 25-year trigger for buildings within three miles of the coastline and 30 years for others; because Stuart sits on the St. Lucie River near the Atlantic, many buildings there qualify for the 25-year trigger, but boards should confirm with Martin County records.
Can a Florida condo board vote to waive SIRS reserve funding?
No. Since the SIRS reforms following the Surfside collapse, associations can no longer vote to waive or reduce reserve funding for structural components covered by the SIRS list under Fla. Stat. 718.112. This is a change from pre-2022 law, when owners could vote to underfund reserves.
Who is qualified to perform a SIRS in Florida?
A licensed engineer or architect must perform the visual inspection required for a structural integrity reserve study under Fla. Stat. 718.112. DBPR oversees condominium compliance generally, but does not itself perform inspections; boards must hire qualified licensed professionals directly.
Do single-family HOAs in Florida need a SIRS?
Generally no. The SIRS mandate under Fla. Stat. 718.112 applies specifically to condominiums and cooperatives (chapters 718 and 719), not standalone HOAs under chapter 720. Some HOAs with attached structures or shared buildings should still confirm their status with counsel.
What happens if a condo association misses its SIRS deadline?
Associations that miss the December 31, 2024 deadline are out of compliance with Fla. Stat. 718.112 and should act quickly with a licensed engineer to complete the study. Consequences can include exposure in resale disclosures, insurance complications, and potential regulatory or legal action; confirm specifics with your association's counsel.
