TL;DR
A reserve study is a professional assessment of a building's common-element components and the money needed to repair or replace them. Florida condos of 3+ stories now need a Structural Integrity Reserve Study (SIRS) under Fla. Stat. 718.112, done by a licensed engineer or architect. Studies typically run $3,000 to $15,000+ depending on building size and complexity.
What is a reserve study?
A reserve study is a physical and financial assessment of a property's shared components, the roof, elevators, pool, paving, plumbing risers, and structural elements, paired with a funding plan for repairing or replacing them over time. A good study does two jobs at once: it inventories what the building has and when each component is likely to fail, and it tells the board how much money to set aside each year so a special assessment doesn't ambush owners. Most studies cover a 20 to 30 year horizon. The provider walks the property, reviews maintenance records, estimates remaining useful life for each component, and models the association's reserve fund against future costs. The output is usually a bound report with a component list, cost estimates, and a recommended funding schedule (straight-line or component method). For Florida condos, this generic reserve study has been partly replaced, or supplemented, by a statutory version: the Structural Integrity Reserve Study (SIRS). SIRS is narrower in scope (it covers specific structural components, not landscaping or amenities) but it is now a legal requirement, more than a best practice. See our reserve study overview for how the general concept maps onto Florida's statute.
What is a reserve study for an HOA?
For a homeowners association, a reserve study works the same way conceptually: an inventory of shared assets (roads, clubhouse, pool, retention ponds, gates) with a savings plan attached. The key difference from condos is legal, not mechanical. Florida's SIRS requirement under Fla. Stat. 718.112 applies to condominium associations, specifically buildings three stories or more in height [1]. HOAs are governed by chapter 720, which does not currently impose the same structural reserve study mandate. That doesn't mean HOA boards should skip it. Roads, drainage, and clubhouse roofs fail on their own schedule regardless of statute. Lenders increasingly ask for reserve documentation on HOA loan and refinance applications, and Fannie Mae's condo and co-op eligibility guidance already looks at reserve funding adequacy during project reviews [1]. An HOA board that never commissions a study is flying blind on the single biggest line item most associations mismanage: not having enough saved for the roof or the road when it finally needs replacing. See hoa reserve study for how HOAs typically structure this even without a statutory trigger.
What is a SIRS and how is it different from a regular reserve study?
A Structural Integrity Reserve Study, or SIRS, is Florida's mandatory, narrower version of a reserve study. It applies to condominium and cooperative buildings three stories or more in height, and it must be performed by a licensed engineer or architect, not a generalist reserve specialist [1]. Under Fla. Stat. 718.112(2)(g), 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 any other item with a deferred maintenance expense or replacement cost exceeding $10,000 that would affect habitability or safety [1]. The statute's actual language: SIRS means "a study of the reserve funds required for future major repairs and replacement of the common areas based on a visual inspection of the reserve components" [1]. A generic reserve study, by contrast, can cover anything the board wants studied, pools, tennis courts, landscaping irrigation, and it can be done by a reserve specialist without an engineering license. Boards that only need the statutory SIRS scope can sometimes save money by having the engineer scope just the required components, then handling non-structural reserve planning separately or in-house. Boards that want one document covering everything sometimes commission both together. Confirm the scope split with your association's counsel, because some management companies bundle them by default and charge accordingly.
How much does a reserve study cost?
| Building size | Under 50 units, single building | 200+ units, multiple buildings | |
|---|---|---|---|
| Age/condition | Newer construction, good records | 30+ years, deferred maintenance | |
| Coastal exposure | Inland, minimal corrosion risk | Waterfront, salt air, visible spalling | |
| Testing needed | Visual inspection only | Concrete coring, invasive testing | |
| Study type | Update (every 3-5 yrs) | Initial full study | Get at least two or three quotes and ask each provider exactly what's included: is it visual-only, does it include a written funding plan with multiple scenarios, and does the fee cover a follow-up call to the board? Boards sometimes get quoted a low number for a bare-bones report and are surprised when the funding plan section is thin or generic. |
Reserve study and SIRS pricing varies a lot by building size, age, complexity, and whether it's a first-time study or an update. As a rough range across the industry, expect roughly $3,000 to $6,000 for a straightforward mid-size building's first full study, and $8,000 to $20,000+ for larger, older, or structurally complex high-rises, especially coastal buildings needing more invasive inspection of waterproofing and concrete. Update studies (every 3 to 5 years, without a full physical inspection) usually cost less than the initial full study. Several things push cost up: total square footage and number of buildings, age and prior maintenance history, whether the engineer needs destructive or semi-destructive testing (concrete coring, rebar exposure) to assess spalling, and travel or mobilization cost for remote or barrier-island properties. A single-building 40-unit condo in a landlocked suburb will cost meaningfully less than a 200-unit oceanfront tower needing invasive concrete testing. Here's a rough comparison of what drives the range: | Factor | Lower cost end | Higher cost end |
Who is legally qualified to perform a Florida SIRS?
Fla. Stat. 718.112(2)(g) requires SIRS to be performed by a licensed engineer or architect [1]. This isn't optional and it isn't something a management company or a general reserve consultant can sign off on for the structural portions, even if that consultant is experienced. DBPR, Florida's Department of Business and Professional Regulation, oversees licensing for engineers (jointly with the Florida Board of Professional Engineers) and maintains license lookup tools boards can use to confirm a provider's license is active and in good standing [1]. Before signing a contract, ask for the engineer's or architect's license number and verify it directly rather than taking a business card at face value. This matters because a study performed by an unlicensed provider may not satisfy the statutory requirement, potentially leaving the association exposed if the deficiency surfaces later during a milestone inspection or a sale. Some firms market themselves as "reserve study specialists" without engineering licensure. They may be perfectly capable for a non-SIRS, amenities-and-landscaping style reserve study, but they cannot legally stamp the structural SIRS components. Ask directly: "Is the SIRS portion of this report going to be signed and sealed by a Florida-licensed engineer or architect?" A legitimate provider answers that without hesitation.
What should a board look for when vetting reserve study providers?
Start with licensure, then move to experience with buildings like yours. A board evaluating providers should ask for: current Florida engineer or architect license and DBPR verification [1], sample reports (redacted for other clients is fine) so the board can see report depth and clarity, references from at least two other Florida condo boards, ideally in a similar coastal zone or building age bracket, and a clear written scope of what's included (visual-only vs. destructive testing, number of components covered, funding plan detail). Ask pointed questions about timeline. A full SIRS for a mid-size building typically takes 4 to 8 weeks from site visit to final report, longer if concrete testing is needed or if the engineer is backed up (which many are, given the volume of Florida buildings now required to comply). Ask what happens if the report reveals urgent safety issues, does the provider notify the board immediately, or does it sit until the final report is delivered? Watch for a few red flags: a quote that's dramatically lower than every other bid (something is probably being skipped), a provider who won't put license numbers in writing, or a firm that pressures the board to sign before showing a sample report. This is not a decision to rush. Two associations in the same county having two very different experiences with the same engineering firm is common enough that references genuinely matter.
How much should an HOA or condo have in reserves?
There's no single dollar figure that fits every property; the honest answer is "enough to fund the components in your specific reserve study without a special assessment." That said, Florida's statutory funding requirement for condo SIRS components changed the math for many boards starting with fiscal year 2025 budgets: associations must fully fund reserves for SIRS-covered components based on the study's findings, with no more waiving or underfunding those specific line items via membership vote [2]. Under the reserve fund relief provisions signed into law (SB 4-D as amended and later legislation), boards can, under certain conditions, use alternatives like a line of credit or a delayed contribution schedule for some SIRS deficits, but the underlying obligation to address the study's findings doesn't disappear [2]. See florida condo reserve fund relief for how that mechanism actually works and its limits. For non-SIRS components and for HOAs generally, industry guidance (Community Associations Institute and reserve specialists) commonly targets a "percent funded" benchmark, comparing actual reserve balance to the ideal balance given component age and depreciation. A commonly cited healthy range is 70% funded or higher, though this is an industry rule of thumb from reserve professionals, not a statutory number, and boards should treat it as a benchmark rather than a legal minimum.
What is an HOA assessment, and how is it different from reserves?
An HOA or condo assessment is simply the regular fee owners pay to fund association operations, this covers landscaping, insurance, management fees, utilities for common areas, and contributions to the reserve fund. It's usually billed monthly or quarterly and is set by the board's annual budget. A special assessment is a separate, additional charge levied outside the normal budget cycle, typically to cover an unexpected or underfunded cost: a major repair, a structural deficiency found during a milestone inspection, or a reserve shortfall the study revealed. Special assessments are the mechanism boards reach for when reserves weren't sufficient to cover the actual cost of a needed repair. The connection to reserve studies is direct: a well-funded reserve, informed by an accurate study, is the single best tool a board has for avoiding special assessments. Boards that skip or underfund their SIRS obligations are, in effect, choosing to push the cost onto owners later as a lump sum rather than spreading it out as regular assessment contributions. See hoa special assessment and condo special assessment insurance for how boards and owners can plan around this risk.
Are HOA special assessments tax deductible?
Generally, no, not for a typical homeowner using the property as a personal residence. The IRS treats special assessments for improvements to common property similarly to capital improvements: they're usually added to the owner's cost basis in the property rather than deducted in the year paid [3]. This can reduce capital gains tax when the unit is eventually sold, but it isn't an immediate deduction. There are exceptions worth knowing about. If the unit is a rental property, special assessments related to repairs and maintenance may be deductible as a rental expense in the year paid, while assessments for capital improvements to a rental property are typically depreciated over time rather than deducted immediately [3]. If a special assessment is specifically for a casualty loss repair (storm damage, for example) there may be different treatment depending on insurance reimbursement and the specific facts. This is genuinely a tax question, not a board-operations question, and the right answer depends on the owner's specific situation (primary residence vs. rental, itemizing vs. standard deduction, state of residence). Owners should talk to a CPA rather than relying on a board notice or a general article. IRS Publication 527 covers rental property expense treatment in more detail [3].
How does a reserve study connect to the milestone inspection deadline?
Milestone inspections and SIRS are related but separate requirements, and boards sometimes conflate them. The milestone inspection under Fla. Stat. 553.899 is a structural inspection of the building performed by a licensed engineer or architect, required at 25 years of age (30 years if not on the coast) and every 10 years after, with the clock starting from the certificate of occupancy date . Its purpose is to assess structural safety. SIRS, under Fla. Stat. 718.112, is the reserve funding study, it looks at the same categories of structural components but from a cost and funding perspective, not a pure safety inspection. The two studies often get scheduled together because the same engineer walking the building for one can efficiently gather data for the other, but they answer different legal questions: is the building structurally sound right now, versus, how much money does the association need to save for future repairs. Boards juggling both deadlines on the same calendar, along with insurance renewal, budget season, and annual meeting prep, often lose track of which report is due when. That's the exact problem a structured compliance calendar solves: matching your building's age, height, and location to the actual statutory dates, then tracking which licensed professional needs to be engaged for which report. If you'd rather not rebuild that timeline from scratch every year, the $199 Building-Specific Board Compliance Kit at /board-kit-builder organizes these deadlines and vendor communications by your building's specific profile; it doesn't replace the licensed engineer's inspection or study, but it keeps the board from missing the date to hire one.
What happens if a board skips or delays the reserve study?
Skipping SIRS isn't a quiet risk-management shortcut, it's a compliance gap with consequences. Florida law requires condo associations subject to the milestone inspection requirements to complete SIRS on the statutory schedule, and boards that don't may face difficulty later: at resale, buyers' lenders increasingly ask for SIRS documentation, and title companies and real estate attorneys are flagging its absence during closings. There's also a practical cost to delay. The longer a building goes without an accurate reserve study, the harder it is to reconstruct component condition and remaining useful life retroactively, especially after storm events, roof leaks, or a change in management company that loses institutional records. An association that delays its SIRS by a year or two isn't just delaying paperwork, it's often delaying the moment it discovers it needs a special assessment, which gives owners less time to plan and the board less time to spread the cost over. Boards juggling limited budgets sometimes try to save money by hiring the cheapest available provider or skipping the study for a cycle. Given the DBPR licensing requirement and the specific statutory scope, this is one area where cutting corners tends to cost more later, either in redone reports, in special assessment sticker shock, or in resale friction.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment of a property's shared physical components (roof, structure, plumbing, elevators) paired with a funding plan showing how much the association should save each year to repair or replace them without a surprise special assessment. In Florida, the structural version required by statute is called a SIRS.
What is a reserve study for an HOA?
For an HOA, a reserve study inventories shared assets like roads, clubhouses, and pools, then models how much the association needs to save annually to fund future replacement. Florida's SIRS statute (Fla. Stat. 718.112) applies to condos, not HOAs, but many HOA boards commission similar studies voluntarily for financial planning.
How much does a reserve study cost in Florida?
Costs typically range from about $3,000 for a smaller, straightforward building's first study to $15,000-20,000+ for large, older, or coastal high-rises needing invasive concrete testing. Get multiple quotes and confirm whether the price covers visual inspection only or includes destructive testing and a full funding plan.
How much should an HOA have in reserves?
There's no universal dollar figure; it depends on your specific components and their remaining useful life per your reserve study. Industry reserve specialists commonly use 70% funded (actual balance vs. ideal balance for component age) as a healthy benchmark, though this is a professional rule of thumb, not a legal requirement outside Florida's SIRS rules.
What is an HOA assessment?
An HOA assessment is the regular fee owners pay, usually monthly or quarterly, to fund the association's budget, covering operating costs and reserve contributions. A special assessment is a separate, additional charge levied outside the regular budget, usually to cover an unexpected repair or reserve shortfall.
Are HOA special assessments tax deductible?
Generally no, for a primary residence, special assessments for capital improvements are added to the owner's cost basis rather than deducted immediately, per IRS guidance on rental and personal property expenses. Rental property owners may deduct repair-related assessments differently. Consult a CPA for the specific facts of your situation.
Who can legally perform a Florida SIRS?
Fla. Stat. 718.112(2)(g) requires the Structural Integrity Reserve Study to be performed by a licensed engineer or architect. Boards should verify the provider's active Florida license through DBPR before signing a contract; a general reserve consultant without engineering licensure cannot legally sign off on SIRS structural components.
What's the difference between a reserve study and a SIRS?
A general reserve study can cover any shared asset (pools, landscaping, roads) and can be done by a reserve specialist. SIRS is Florida's narrower, mandatory version covering specific structural components (roof, load-bearing walls, foundation, plumbing, electrical, waterproofing, and windows), and it must be performed by a licensed engineer or architect.
How often does a Florida condo need a SIRS?
SIRS is generally required for condo buildings three stories or more, tied to the same aging schedule as milestone inspections. Boards should confirm the exact update cycle and any transitional deadlines with their association's counsel, since specific timing provisions have been adjusted by the legislature more than once since 2022.
Does an HOA need a milestone inspection or SIRS?
No. Both the milestone inspection (Fla. Stat. 553.899) and SIRS (Fla. Stat. 718.112) apply specifically to condominium buildings, not HOAs governed by chapter 720. HOA boards can still voluntarily commission structural inspections or reserve studies as good practice, especially for aging common structures.
What happens if a board never gets a reserve study done?
Beyond the compliance issue for SIRS-required condos, skipping a reserve study usually means the board is guessing at reserve funding levels. That guesswork tends to end in a large special assessment when a major component fails unexpectedly, since there was no funding plan or component-by-component cost projection in place.
Can a board use a cheaper, non-engineer reserve consultant instead of an engineer for SIRS?
No, for the SIRS structural components specifically. Fla. Stat. 718.112(2)(g) requires a licensed engineer or architect. A non-licensed reserve consultant may still be useful for non-SIRS reserve items like landscaping or amenities, but cannot substitute for the statutory SIRS provider.
