TL;DR
SIRS (Structural Integrity Reserve Study) is a Florida-required inspection and funding study for condo buildings 3 stories or taller. It covers 10 structural components, sets minimum reserve funding with no waiver allowed, and must be done by a licensed engineer or architect at least every 10 years under Florida Statutes 718.112.
What is SIRS in Florida?
SIRS stands for Structural Integrity Reserve Study. It's a Florida law that forces condo associations to get a licensed engineer or architect to inspect specific structural parts of the building, then use that inspection to calculate how much money the association has to keep in reserves for each item. It applies to condominium buildings that are three stories or taller, per Florida Statutes 718.112(2)(g) [1]. This isn't a general reserve study like you might see in other states. Florida law spells out exactly which components have to be studied: roof, load-bearing walls, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, windows and doors, and "any other item that has a deferred maintenance expense or replacement cost that exceeds $10,000 and directly affects the structural integrity of the building" [1]. The law came out of the Surfside condo collapse in June 2021, which killed 98 people. The Florida Legislature responded with SB 4-D in 2022, which created the SIRS requirement and tied it to the existing milestone inspection law. If you're dealing with a milestone inspection deadline too, see our milestone inspections guide for how the two overlap.
Which buildings need a SIRS?
Any condominium association with a building three stories or higher needs a SIRS, regardless of when the building was constructed. There's no exemption based on age. Single-family homes, townhomes, and most non-condo HOAs are not covered by this specific statute, though many HOAs voluntarily do similar studies. The statute counts stories from the ground, and DBPR guidance treats any residential condominium building meeting that height threshold as in scope, including mixed-use buildings with condo units above commercial space [1]. If your association has multiple buildings, each building generally needs its own SIRS because the structural condition varies by building. The first SIRS deadline for most existing associations was December 31, 2024, though the Legislature pushed this back for some buildings under 2023 amendments. Confirm your specific deadline with your association's counsel, since compliance dates have shifted more than once and depend on your milestone inspection due date and county [1].
What is a reserve study?
A reserve study is a professional analysis that looks at the major physical components of a property (roofs, paving, pools, structural elements) and estimates when each one will need to be repaired or replaced and how much that will cost. The study then calculates how much money the association should be setting aside each year to have the cash on hand when the bill comes due. Most reserve studies get updated every 3 to 5 years to reflect new costs and updated remaining useful life estimates. A full study (with an on-site visual inspection) is called a Level I or Level II study depending on the firm and standard used; some providers do an in-house "Level III" update between full studies. Reserve study standards in Florida for SIRS purposes are set by statute, not by industry associations, which makes SIRS more rigid than a typical voluntary reserve study elsewhere. For general background, see our reserve study guide.
What is a reserve study for an HOA?
For a homeowners association (as opposed to a condo), a reserve study works the same way conceptually: an inspection of shared components (roads, clubhouse, pool, irrigation, drainage) paired with a funding schedule. The difference is legal, not technical. Florida doesn't currently impose a SIRS-style mandatory structural reserve study on most HOAs the way it does on condos under 718.112. Some HOAs do have structural elements, like a clubhouse or parking garage, where a voluntary reserve study makes just as much sense as it does for a condo. Boards that skip this step often get blindsided by a special assessment when the roof or the parking structure finally fails. For HOA-specific mechanics, see our HOA reserve study article. If your community is a cooperative or a condo under 3 stories, you may be exempt from SIRS specifically, but Florida Statutes 720 (governing most HOAs) and 719 (co-ops) still require standard reserve funding disclosures. Ask your manager or counsel which chapter actually governs your association, because condo, co-op, and HOA rules are not interchangeable.
What is an HOA assessment (and how is it different from SIRS)?
An HOA assessment is a fee the association charges owners to cover shared expenses. Regular assessments (sometimes called dues) fund the annual operating budget and reserves. A special assessment is a one-time or short-term charge on top of regular dues, usually because there's a big unexpected cost or a reserve shortfall that regular dues weren't sized to cover. SIRS itself is not an assessment. It's the study that tells the board how big the reserve assessments (regular or special) need to be. If a board discovers through SIRS that it's underfunded for a roof replacement in 5 years, the board typically responds by raising regular reserve contributions, levying a special assessment, or some mix of both. Under current Florida law, once a SIRS is complete, associations generally cannot vote to waive or reduce reserve funding for the structural components identified in the study, unlike the old rule that let owners vote annually to waive reserves entirely. This is one of the biggest post-Surfside changes and it's a big reason boards are seeing special assessments they didn't see before [1]. For deeper detail, read our HOA special assessment guide.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure or percentage that Florida law sets as the "right" reserve level for every association, because it depends entirely on your building's age, size, components, and local repair costs. What the law does require, for SIRS components specifically, is full funding based on the study's findings, calculated using the straight-line method or another accepted actuarial method, with no more underfunding through a members' waiver vote [1]. A rough industry rule of thumb some reserve professionals use is that a healthy reserve fund should sit above roughly 70% funded (actual reserves divided by the ideal fully-funded amount), though this isn't a Florida statutory requirement, it's a common benchmark used more broadly in the reserve study industry [2]. Associations sitting below 30% funded are generally considered at higher risk of a painful special assessment. The honest answer for a Florida SIRS building is this: whatever the licensed engineer's study says you need for the 10 structural components, funded on a schedule that doesn't leave gaps. Underfunding those specific items is no longer a board discretion issue once SIRS is done. It's closer to a compliance issue [1].
How much does a reserve study cost?
Cost varies by building size, number of components, and whether it's a first-time SIRS or an update. For a full SIRS with a site visit by a licensed engineer or architect, boards commonly report figures somewhere in the $3,000 to $15,000+ range depending on building size and complexity, though larger or more complex buildings (multiple towers, extensive parking structures) can run higher. There's no statutory fee schedule, and DBPR does not set or cap reserve study pricing, so get at least two or three quotes from licensed providers. A milestone inspection (the separate structural inspection required at 25 or 30 years depending on coastal proximity) is a different scope and cost than SIRS, though some engineering firms bundle the two since they overlap on structural components. Don't assume one covers the other; ask the firm in writing exactly which statute (718.112 SIRS vs. 553.899 milestone) each report satisfies [1] [3]. Because pricing isn't standardized, boards frequently overpay for redundant work or underpay for a rushed report that misses required components. This is exactly the kind of task where organizing your paperwork trail matters: the $199 Building-Specific Board Compliance Kit helps boards track which inspections and studies are due, what each one should cover under the statute, and keep the documentation straight for owners and buyers asking questions.
Are HOA special assessments tax deductible?
Generally, no, for a typical owner-occupied unit. Special assessments for repairs, reserves, or capital improvements to common areas are usually treated as a nondeductible personal expense by the IRS, similar to how a homeowner can't deduct the cost of a new roof on their own house. The IRS doesn't have a dedicated publication solely on condo special assessments, but the general rule comes from the personal, nondeductible nature of home improvement and maintenance costs, and from the repair-versus-improvement distinction covered in IRS Publication 527 for rental property [4]. There are exceptions. If the unit is a rental property, a special assessment for repairs may be deductible as a business expense in the year paid, and an assessment for a capital improvement generally needs to be depreciated over time rather than deducted immediately, per the rules in IRS Publication 527 on rental property expenses versus improvements [4]. If part of the assessment funds a casualty loss repair (like storm damage) there can be narrower deductions available, but personal casualty loss deductions were tightened significantly after 2017 tax law changes and are now mostly limited to federally declared disasters, per IRS guidance on casualty losses [5]. This is genuinely a "talk to your accountant" situation, not a blanket yes or no. The distinction between repair versus improvement, and personal residence versus rental, changes the answer. For general assessment mechanics, our HOA special assessment article covers how these charges get levied in the first place, though it isn't tax advice either.
What happens if a condo association doesn't complete its SIRS on time?
Associations that miss their SIRS deadline are out of compliance with Florida Statutes 718.112, which can expose the board to legal and financial risk, including potential liability claims from owners and complications during unit sales, since buyers and lenders increasingly ask for SIRS documentation before closing. DBPR can also investigate complaints related to condominium statutory compliance under its regulatory authority over community association managers and associations. Beyond the legal exposure, the practical risk is bigger: without a completed SIRS, the board has no defensible number for what reserves should be. That means special assessments tend to arrive as emergencies instead of planned expenses. Lenders like Fannie Mae have also tightened condo project review standards post-Surfside, and buildings without current SIRS or milestone documentation can end up on ineligible or unwarrantable lists, which chokes off financing for buyers in the building [3]. If your association is behind, the fix isn't complicated, it's just urgent: get quotes from licensed engineers or architects now, get the study scheduled, and start budgeting for what it will likely find before the number gets forced on you by a special assessment vote.
Who can perform a SIRS in Florida?
Only a licensed engineer or licensed architect can perform the visual inspection and prepare the SIRS report for the structural components listed in the statute. Florida Statutes 718.112(2)(g) requires that the study be based on a visual inspection performed by a licensed engineer or architect [1]. Reserve study firms that aren't licensed as an engineering or architecture practice generally can't sign off on the structural component inspection portion, even if they handle the financial and funding calculations. DBPR licenses and regulates community association managers, but doesn't itself perform or certify SIRS studies. Check any engineer or architect's license status directly through the Florida Department of Business and Professional Regulation's license search before you sign a contract. Boards sometimes get pitched by "reserve specialists" who aren't licensed engineers. That's fine for a voluntary reserve study on non-structural components, but it does not satisfy the SIRS requirement for the 10 statutory structural items. Confirm licensing in writing before you pay a deposit.
How does SIRS relate to the milestone inspection?
The milestone inspection (Florida Statutes 553.899) is a separate structural safety inspection required for condo and cooperative buildings 3 stories or taller, generally due at 25 years from the certificate of occupancy for buildings within 3 miles of the coastline, and 30 years for buildings farther inland, with recertification every 10 years after [3]. SIRS is the reserve funding study; the milestone inspection is the structural safety inspection. They overlap on subject matter (both look at structural components) but they serve different legal purposes and often have different deadlines. Some engineering firms will do both studies in a single site visit to save cost, which is smart if your building's timing allows it. If you haven't nailed down your milestone deadline yet, our milestone inspections hub walks through the 25 vs 30 year distinction and how coastal proximity is measured. Boards that treat these as one requirement sometimes miss that SIRS needs updating on its own cycle (at least every 10 years) even if the milestone inspection isn't due again yet. Track them as two separate line items on your compliance calendar, not one.
What are the 10 required SIRS components?
| Roof | Common source of large deferred-maintenance cost | |
|---|---|---|
| Load-bearing walls / other primary structural members | Core structural integrity | |
| Floor | Structural support and safety | |
| Foundation | Building stability | |
| Fireproofing and fire protection systems | Life safety compliance | |
| Plumbing | Leak and water intrusion risk | |
| Electrical systems | Fire and safety risk | |
| Waterproofing and exterior painting | Building envelope protection | |
| Windows and doors | Water intrusion and structural seal | |
| Any other item with deferred maintenance/replacement cost over $10,000 affecting structural integrity | Catch-all for building-specific risks | This list comes directly from the statute [1]. Notice what's not on it: pools, clubhouses, landscaping, parking lot resurfacing. Those still need funding through a general reserve plan, but they're not subject to the no-waiver SIRS rule the way the 10 structural items are. |

Frequently asked questions
What is a reserve study?
A reserve study is a professional evaluation of a property's major shared components (roof, structure, plumbing, pool, paving) that estimates remaining useful life and replacement cost, then builds a funding schedule so the association isn't caught off guard by a big repair bill. Florida's SIRS is a statutory, structural-focused version of this for condo buildings 3+ stories.
What is a reserve study for an HOA?
It's the same concept as a condo reserve study, applied to HOA-owned common property like roads, clubhouses, pools, and drainage systems. Most HOAs aren't legally required to do one under Florida Statutes 718.112 (that applies to condos), but it's still smart risk management, especially for HOAs with structures like a clubhouse or parking garage.
What is an HOA assessment?
An HOA assessment is a charge levied on owners to fund shared community expenses. Regular assessments cover the annual operating budget and reserve contributions; special assessments are one-time or short-term charges added on top, usually to cover an unexpected repair or a reserve funding shortfall.
What are HOA assessments?
HOA assessments are the fees owners pay to fund the association's operations and reserves, either as recurring dues or as special (one-time) charges for unexpected costs. They're authorized by the association's governing documents and, for special assessments, often require board or membership approval depending on the amount and the documents' terms.
How much should an HOA have in reserves?
There's no single statutory dollar figure for most HOAs, since it depends on building age, components, and local costs. A common industry benchmark used by reserve professionals is staying above roughly 70% funded (actual reserves versus the fully-funded ideal), though this isn't a Florida legal requirement outside SIRS-covered condo buildings.
How much should a condo have in reserves under SIRS?
For the 10 SIRS structural components, Florida Statutes 718.112 requires reserves funded to the level the licensed engineer's study calculates, with no membership vote allowed to waive or reduce that funding once the study is complete. The specific dollar amount depends entirely on your building's condition and components.
How much does a reserve study cost in Florida?
A full SIRS performed by a licensed engineer or architect commonly runs somewhere between $3,000 and $15,000 or more, depending on building size and complexity. There's no state-set fee schedule, so get multiple quotes and confirm in writing which statute (SIRS vs. milestone inspection) the report satisfies.
Are HOA special assessments tax deductible?
Generally no, for a personal residence, since the IRS treats most special assessments for repairs or improvements as nondeductible personal expenses. Rental property owners may be able to deduct repair-related assessments as a business expense or depreciate capital-improvement assessments. Ask a tax professional about your specific situation.
Which buildings need a SIRS in Florida?
Condominium buildings 3 stories or taller need a SIRS under Florida Statutes 718.112(2)(g), regardless of the building's age. Most HOAs, single-family communities, and buildings under 3 stories aren't covered by this specific requirement, though check with counsel since co-op rules differ.
Who can perform a SIRS inspection?
Only a licensed engineer or licensed architect can perform the visual inspection required for a SIRS report under Florida Statutes 718.112. Verify any provider's license through the Florida Department of Business and Professional Regulation before signing a contract.
Is SIRS the same as the milestone inspection?
No. The milestone inspection (Florida Statutes 553.899) is a structural safety inspection due at 25 or 30 years depending on coastal proximity. SIRS is the reserve funding study for structural components. They overlap in subject matter but are two separate legal requirements with separate deadlines.
Can an association still vote to waive reserves after SIRS is complete?
No, not for the structural components covered by SIRS. Once the study is complete, Florida law generally prohibits waiving or reducing reserve funding for those items, which is a major change from the old rule that allowed annual membership votes to waive reserves entirely.
