Structural integrity reserve studies: SIRS explained for boards

Last updated 2026-07-24

What is a reserve study?

A reserve study is a report that looks at the shared property a community owns (roofs, pavement, pools, elevators, structural components) and estimates two things: how much life is left in each item, and how much money the association needs to set aside now so it can pay for replacement later without a surprise bill landing on owners. A generic reserve study covers whatever the association's declaration lists as common elements. It's a budgeting tool, not a safety inspection, and most states leave the decision to fund reserves fully or partially up to the board and the membership. Florida condos got a narrower, mandatory version of this after the Champlain Towers South collapse in Surfside in June 2021. That version is called a structural integrity reserve study, or SIRS, and it isn't optional for buildings that meet the height and story threshold. It's also not the same document as a milestone inspection, though the two often get bundled together because they're both driven by the same 2022 and 2023 legislative sessions. If you want the general mechanics of reserve funding for any HOA, see our reserve study explainer; this article focuses specifically on Florida's SIRS requirement. Boards sometimes confuse a SIRS with a full financial reserve study covering every common element (landscaping, signage, amenity buildings). Florida law layers the SIRS on top of the standard reserve schedule under 718.112(2)(f); it doesn't replace it.

What is a SIRS for a condo association?

A SIRS is a study, performed by a licensed engineer or architect, that inspects specific structural and life-safety components of a condominium building and produces a 30-year estimate of when each component will need replacement, plus what it will cost. Florida Statute 718.112(2)(g) lists exactly what has to be inspected: roof, load-bearing walls or other primary structural members and primary structural systems, 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 affects the structural integrity of the building ^[1]. The statute is specific about who can do it: "a study of the reserves required for future major repairs and replacement of the common areas based on a visual inspection of the property" must be prepared by "a licensed engineer or architect" ^[1]. A property manager, a board member with construction experience, or a generic reserve-study firm without the license can't sign this off. That's a deliberate restriction and it's one reason costs run higher than a typical reserve study. The SIRS applies to condominium buildings that are three stories or more in height, per 718.112(2)(g). Timeshares and buildings under three stories are outside the requirement, though associations can still choose to commission one. Cooperatives got a parallel requirement added under 719.106 covering similar structural components.

How much should an HOA have in reserves?

There's no single dollar figure that's right for every association, because the correct reserve balance depends on the age, size, and component list of the specific building, not a percentage rule of thumb. What matters more than the balance today is whether the association is funding on a schedule that reaches 100% of the estimated replacement cost by the time each component actually needs replacing. For Florida condos subject to SIRS, the law removed the old option to underfund or skip reserve items covered by the study. Starting with the fiscal year that begins Jan 1, 2025, associations must fund SIRS components at the full amount identified in the study, not a board-reduced or waived number ^[1]. Owners can no longer vote to waive or reduce reserves for the specific structural items the SIRS covers, though non-SIRS reserve items may still be waived or reduced by membership vote depending on the association's documents. For a rough sense of scale: a 2022 Florida Senate staff analysis of SB 4-D estimated statewide reserve funding obligations for condominiums subject to the new law would run into the billions of dollars in aggregate, which is part of why special assessments have spiked across the state since the law passed ^[2]. For your own building, the SIRS itself is the only real answer; anyone quoting you a rule of thumb ('save 10% of your budget') is guessing. HOAs that aren't condos and aren't subject to 718.112 don't have a Florida-mandated reserve floor at all. Some national reserve-study associations suggest boards target funding somewhere between 70% and 100% of the fully-funded balance as a health benchmark, but that's industry practice, not law. If your community wants a broader review beyond the mandatory SIRS scope, our hoa reserve study page walks through non-condo reserve planning.

What are HOA assessments and how do they differ from reserves?

An HOA assessment is a fee the association charges owners, usually monthly or annually, to fund operating costs and reserves. Regular assessments cover predictable expenses: insurance, landscaping, management fees, utilities for common areas, and contributions to the reserve fund. A special assessment is a separate, often one-time charge levied when the regular budget and reserves can't cover a specific cost, commonly a large repair, an insurance shortfall, or (increasingly in Florida) a structural repair identified by a milestone inspection or SIRS. Special assessments aren't discretionary padding; boards generally have to levy them when reserves are inadequate to meet a legal or safety obligation, and Florida law requires notice of the specific purpose and estimated cost before the board can impose one under 718.112(2)(c) ^[1]. The SIRS requirement is one of the biggest drivers of special assessments in Florida right now. If a building's reserves were underfunded for years and the SIRS reveals a large near-term repair, the gap often has to be closed with a special assessment because reserves alone can't cover it. For more on how these charges get calculated and disclosed, see hoa special assessment.

How much does a SIRS or reserve study cost?

Small low-rise, under 50 units	$1,500 to $5,000
Mid-size, 50 to 150 units	$5,000 to $12,000
Large high-rise, 150+ units or complex structure	$10,000 to $25,000+	These figures are general industry ranges, not a government-set fee schedule; get at least two or three bids from licensed engineers or architects before committing. A milestone inspection, which is a separate requirement under 553.899 for buildings 3 stories or more once they hit 30 years old (25 years if within 3 miles of the coast), is priced separately and often costs more than the SIRS itself because it involves more invasive testing. Boards sometimes bundle the two studies with the same engineering firm to save on mobilization costs, but they are legally distinct deliverables with different statutory citations. See our milestone inspections hub for that requirement specifically.

Cost depends heavily on building size, number of structural components, and whether an engineer has to access roofs, garages, or below-grade areas. Florida doesn't set a statutory fee, and DBPR doesn't publish a standard price list, so the numbers below come from general market ranges reported by engineering and reserve-study firms operating in the state; treat them as an approximate planning range, not a quote. Smaller buildings (under 50 units, low-rise) commonly see SIRS costs in the $1,500 to $5,000 range. Larger or taller buildings, especially high-rises with more structural systems and harder-to-access components, can run $10,000 to $25,000 or more. Buildings with prior deferred maintenance, difficult site access, or a large number of separate structural systems tend toward the higher end. | Building profile | Typical SIRS cost range |

When is the SIRS deadline and what happens if a building misses it?

The statutory deadline for condominium associations to complete their first SIRS was Dec. 31, 2024, for buildings that reached the three-story, non-timeshare threshold covered by 718.112(2)(g) ^[1]. After the initial study, a new SIRS is required at least every 10 years ^[1]. Several associations pushed for relief as the deadline approached, citing engineer backlogs and cost. The Legislature responded in 2024 with SB 1103, which gave some flexibility on timing and clarified funding mechanics, but it did not eliminate the core requirement. Confirm with your association's counsel whether any extension or phase-in applies to your specific building, because the statute has been amended multiple times since 2022 and county or DBPR guidance can shift the practical deadline. DBPR, the Florida Department of Business and Professional Regulation, is the state agency that regulates condominium associations and licenses community association managers; its Division of Florida Condominiums, Timeshares, and Mobile Homes handles complaints and enforcement related to these statutes ^[3]. Missing the SIRS deadline doesn't automatically dissolve the association, but it does expose the board to potential breach-of-fiduciary-duty claims from owners, and it locks the association out of the ability to waive full funding on the SIRS line items once the study is finally completed. For buildings still catching up, the practical sequence matters: get the SIRS done, get the reserve schedule updated to the full-funding requirement for the fiscal year beginning after the study, and disclose the numbers to owners before the annual budget meeting. Our reserve study for condo association page covers that sequencing in more detail.

Are HOA special assessments tax deductible?

Generally, no, not for the individual owner on their personal federal income tax return, and this is one of the most misunderstood parts of Florida's post-Surfside assessment wave. The IRS treats special assessments the way it treats regular HOA dues: they're a personal living expense, not a deductible one, when the property is your primary residence ^[4]. There are narrow exceptions. If the unit is a rental or investment property, a special assessment for repairs may be deductible as a business expense in the year paid, or it may need to be capitalized and depreciated if it's a capital improvement rather than a repair, per general IRS rules on rental property expenses ^[4]. If part of your home is used for business (a qualifying home office), a proportional share might factor into that deduction. None of this is specific tax advice; a CPA needs to look at your actual unit use and the nature of the assessment (repair versus improvement) to tell you how to treat it. What the special assessment funds (a SIRS-driven structural repair, for instance) doesn't change its tax treatment for the individual owner. The deductibility question turns on how you use the property, not on why the association charged the assessment.

How does the SIRS interact with the milestone inspection?

They're both mandatory structural checks born from the same 2022 legislative response to Surfside, but they answer different questions and sit in different statutes. The milestone inspection (553.899) is a life-safety check: is the building structurally sound right now? The SIRS (718.112(2)(g)) is a funding document: given the building's structural components, how much money does the association need to set aside, and when? A milestone inspection is triggered by building age (30 years generally, 25 years if within 3 miles of the coast) and has to be repeated every 10 years after the initial one ^[5]. A SIRS is triggered by height (3+ stories) and building type (condo, not timeshare), independent of age, and also repeats every 10 years ^[1]. In practice, many boards hire the same engineering firm to do both studies close together, since the visual inspection work overlaps substantially. But a board can't substitute one for the other; DBPR and most association counsel treat them as separate statutory obligations with separate filing and disclosure requirements. If your building is approaching either the 25-year or 30-year mark, our milestone inspections hub breaks down the age and coastal-distance triggers in detail.

What should the board do with the SIRS report once it's done?

The statute requires the association to distribute the SIRS to owners and to use its findings to set the reserve schedule; simply filing it in a drawer doesn't satisfy the law. Practically, a board that just received a SIRS has four jobs to do in sequence. First, get the report reviewed by association counsel and the treasurer together, not separately, so legal and financial reads happen against the same document. Second, update the reserve line items in the next fiscal year's budget to reflect full funding for every SIRS-covered component; partial funding or waivers aren't allowed for these items starting the fiscal year beginning Jan 1, 2025 ^[1]. Third, disclose the funding requirement and any resulting increase in assessments to owners before the budget vote, consistent with the notice requirements in 718.112(2)(c) ^[1]. Fourth, calendar the next SIRS for no later than 10 years out, and calendar the milestone inspection separately if it's coming due. This is exactly the kind of multi-deadline tracking that gets missed when it lives in one board member's inbox. A $199 one-time Board Compliance Kit built around your building's specific age, height, and coastal distance organizes these dates, the required disclosures, and the vendor documentation in one place, so a board turnover doesn't mean starting from zero. It doesn't replace the engineer or the SIRS itself; it keeps the paperwork and deadlines straight around the professional work the statute requires.

Who actually performs a SIRS and how do you vet them?

Florida law requires the study to be prepared by a licensed engineer or architect ^[1]. Verify the license directly through DBPR's licensee search, since Florida's Board of Professional Engineers and Board of Architecture and Interior Design both maintain public license lookups through the department's licensing portal ^[3]. Beyond the license check, ask for references from other condo boards where the firm has completed a SIRS, ask how many similar buildings (height, age, construction type) they've studied, and get the fee and scope in writing before signing. Some firms bundle the SIRS with the milestone inspection at a discount since site visits overlap; that's a legitimate cost-saver, but confirm the deliverables are still two distinct, separately labeled reports, because lenders, insurers, and buyers may ask for them individually.

What happens to reserves and assessments if the building fails the SIRS or milestone process?

There's no formal 'pass or fail' grade on a SIRS the way there might be on a milestone inspection's phase two structural report. The SIRS produces a funding number, not a verdict. If that number is large relative to current reserves, the board's options are limited: raise regular assessments, levy a special assessment, seek association financing (a loan against future assessment income), or some combination. Some relief has come through legislative amendments; SB 154 (2023) and later adjustments gave associations somewhat more flexibility on how quickly the full-funding requirement phases in and clarified certain calculation methods, and there's ongoing legislative discussion about further relief for financially stressed associations ^[1]. Boards should not assume any relief applies automatically to their building. Check current status with association counsel, and see our page on florida condo reserve fund relief for what's changed most recently, since this is one of the fastest-moving parts of Florida condo law and generic advice goes stale within a legislative session.

Frequently asked questions

What is a reserve study?

A reserve study is a report estimating the remaining useful life and future replacement cost of a community's shared components (roofs, pavement, structural systems, and more), used to set how much money an association should save each year. In Florida, condos 3+ stories must get a specific, structural-focused version called a SIRS under Fla. Stat. 718.112(2)(g).

What is a reserve study for an HOA?

For a homeowners association, a reserve study covers whatever common elements the declaration assigns to the HOA, like roofs on attached units, private roads, pools, or clubhouses. Unlike Florida's condo SIRS, most HOA reserve studies aren't mandated by state statute; the board and governing documents decide whether one is required and how detailed it needs to be.

What is an HOA assessment?

An HOA assessment is a fee charged to owners to fund the association's operating budget and reserves. Regular assessments are recurring (monthly or annual); special assessments are one-time or short-term charges for costs the regular budget and reserves can't absorb, such as a structural repair identified by a SIRS or milestone inspection.

How much should an HOA have in reserves?

There's no universal dollar target; the right reserve balance depends on the building's age, size, and component list as documented in its own reserve study or SIRS. For Florida condos subject to SIRS, the law now requires full funding of the study's identified structural items starting the fiscal year beginning Jan 1, 2025, with no board waiver allowed for those items.

How much does a reserve study cost?

A general (non-SIRS) reserve study for a smaller HOA can run roughly $1,000 to $3,000. A Florida condo SIRS, which requires a licensed engineer or architect and covers specific structural components, typically runs $1,500 to $5,000 for small buildings and $10,000 to $25,000+ for large high-rises, based on general industry pricing, not a state fee schedule.

Are HOA special assessments tax deductible?

Generally no, for a primary residence, the IRS treats special assessments like regular dues: a nondeductible personal expense. Exceptions can apply for rental or investment properties, where a repair-type assessment may be deductible in the year paid and a capital-improvement-type assessment may need to be depreciated. Talk to a CPA about your specific unit use.

What is the deadline for Florida's structural integrity reserve study (SIRS)?

The initial SIRS deadline for qualifying condominiums (3+ stories, non-timeshare) was Dec. 31, 2024, under Fla. Stat. 718.112(2)(g). After that, associations must complete a new SIRS at least every 10 years. Some buildings sought timing relief through later legislation; confirm current status with your association's counsel.

Is a SIRS the same as a milestone inspection?

No. A milestone inspection (Fla. Stat. 553.899) checks whether an aging building is structurally sound, triggered by 30 years of age (25 if within 3 miles of the coast). A SIRS (718.112(2)(g)) is a funding study estimating reserve needs for structural components, triggered by building height (3+ stories), regardless of age.

Who is required to perform a SIRS in Florida?

Only a licensed engineer or architect can prepare a structural integrity reserve study under Fla. Stat. 718.112(2)(g). Boards should verify the professional's license through DBPR's licensee search before hiring, since an unlicensed reserve-study firm can't legally satisfy this requirement.

Can owners vote to waive SIRS reserve funding?

No, not anymore for the specific components a SIRS covers. Starting with the fiscal year beginning Jan 1, 2025, Florida law removed the option for membership to waive or reduce reserve funding for SIRS-identified structural items. Non-SIRS reserve items may still be waivable depending on the association's documents.

What components does a SIRS have to inspect?

Fla. Stat. 718.112(2)(g) lists roof, load-bearing walls or primary structural systems, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, windows, and any other item with a deferred maintenance or replacement cost over $10,000 affecting structural integrity.

What happens if my condo association misses the SIRS deadline?

There's no automatic dissolution, but missing the deadline exposes board members to potential breach-of-fiduciary-duty exposure and removes the association's ability to waive full reserve funding once the study is eventually completed. It can also complicate insurance renewal and unit resale, since lenders and buyers increasingly ask for SIRS status.
