TL;DR
A reserve fund study is a professional inspection and financial report that tells your association how much money to save, and how fast, to replace roofs, structures, plumbing, and other big-ticket items before they fail. Florida condos of 3+ stories must get a structural reserve study by a licensed engineer or architect, with updates every 10 years, under Fla. Stat. 718.112(2)(f)2.
What is a reserve study?
A reserve study is a physical inspection and financial forecast, done together, that answers one question: how much should this building be setting aside every month so it can pay for roof replacement, repaving, elevator overhauls, and structural repairs without a surprise bill landing on owners. A real reserve study has two halves. The physical half is a component inventory: someone walks the property, lists every major common-element asset (roof, paint, pavement, pool deck, elevators, load-bearing walls, waterproofing, and more), estimates its remaining useful life, and prices out its replacement cost today. The financial half takes that inventory and models a funding plan, usually 20 to 30 years out, showing what the reserve balance would look like under different contribution levels. In Florida, as of the 2022 and 2023 legislative overhauls following the Champlain Towers South collapse, there are now two distinct things people call "reserve studies" and boards need to keep them straight. There's the traditional financial reserve study (covers roofs, paving, painting, and other components, funding advice only, no license required by statute). And there's the Structural Integrity Reserve Study (SIRS), a new statutory requirement that covers specific structural components and must be prepared by a licensed engineer or architect [1]. They overlap in purpose but not in legal weight. Only the SIRS is mandatory under current Florida condo law, and only for buildings that meet the height and story threshold. For the deep mechanics of what a SIRS must contain, see our reserve study guide.
What is a reserve study for an HOA (versus a condo)?
Homeowners associations (HOAs) in Florida are not currently subject to the same mandatory structural reserve study law that applies to condominiums. Chapter 720 of the Florida Statutes, which governs HOAs, does not impose a SIRS requirement the way Chapter 718 does for condos [2]. If your community is an HOA of single-family homes or townhomes where owners hold the roof and structure themselves, you likely fall outside SIRS entirely. But plenty of "HOAs" are actually multi-story condominium buildings organized under a homeowners' association name in casual conversation, and plenty of HOAs still choose to run a voluntary reserve study because it's good practice, not because a statute demands it. A voluntary HOA reserve study works the same way: an inspection of common-area assets (community pool, clubhouse, gated entry, private roads, retention ponds) paired with a funding schedule. The practical answer for HOA boards: check whether your community includes buildings of three stories or more that share condominium-style common elements. If yes, get counsel to confirm whether Chapter 718 SIRS rules apply to any part of your structure. If your HOA is straightforward single-family homes, a reserve study is a financial planning tool you choose to commission, not a legal mandate. See our hoa reserve study breakdown for the specifics.
What is an HOA assessment (and what is a special assessment)?
An HOA assessment is the regular fee every owner pays, usually monthly or quarterly, that funds day-to-day operations and reserve contributions. It is the association equivalent of a mortgage escrow payment: routine, budgeted, and disclosed in the annual meeting materials. A special assessment is different. It's a one-time (or short-series) charge levied outside the regular budget, almost always because reserves ran short of an unexpected or underfunded expense: a roof that failed early, a structural repair flagged by a milestone inspection, insurance premiums that spiked mid-year, or a SIRS-driven funding catch-up. Florida condo associations can levy special assessments under the authority in their declaration and under Fla. Stat. 718.116, which governs assessment liability and lien rights [3]. The link between reserve studies and special assessments is direct and it's the whole reason boards should care about this topic: a well-funded reserve, informed by an accurate reserve study, is what prevents a special assessment. Underfund reserves for a decade and the math doesn't disappear, it just becomes somebody's emergency invoice. For more on how these interact, see hoa special assessment and condo special assessment insurance.
How much should an HOA (or condo) have in reserves?
| Strong | 70%+ | Low special assessment risk in near term |
|---|---|---|
| Adequate | 40-69% | Manageable, watch upcoming big-ticket items |
| Weak | 30-39% | Special assessment likely within 3-5 years |
| Critical | Under 30% | High risk of near-term special assessment or loan |
There's no single dollar figure, because the right reserve balance depends on your building's age, component inventory, and replacement costs, not a percentage rule of thumb. But Florida law now gives condos a hard funding floor for structural components covered by SIRS: full funding, no waiving allowed for those specific line items, starting with reports due by December 31, 2024, with contributions required in the budget adopted after that report [1]. Under the pre-2022 rules, condo boards could vote each year to waive or reduce reserve funding, which is a major reason so many buildings arrived at their 30-year mark structurally sound but financially unprepared. That waiver option is now eliminated specifically for SIRS components: roof, structure, load-bearing walls, floor, foundation, fireproofing, plumbing, electrical, waterproofing, and pool decks (per DBPR guidance on the components covered) [4]. Non-SIRS components like painting or landscaping can still be waived or underfunded by member vote, but the structural items cannot. A widely cited industry rule of thumb from reserve study professionals is that a well-funded association should sit around 70% funded (actual reserve balance divided by the ideal fully-funded balance) as a healthy benchmark, though this is an industry convention from firms like the Community Associations Institute and Association Reserves, not a statutory number [5]. Below 30% funded is generally considered a red flag that a special assessment is likely within a few years. There is no Florida statute that sets a required percentage; the law instead requires the study itself and, for SIRS items, full funding of the calculated need. | Reserve health | Approx. % funded | What it usually means |
How much does a reserve study cost?
Cost depends heavily on building size, number of components, and whether you need a full statutory SIRS (structural, engineer-stamped) or a standard financial reserve study. There is no single statewide fee schedule; DBPR does not set reserve study pricing, only the licensing requirements for who can perform them [4]. Industry surveys and reserve study firms generally cite ranges in the $1,000 to $5,000 range for a standard financial reserve study on a small to mid-size community, with larger or more complex properties running higher. For Florida's mandatory SIRS specifically, because it requires a licensed engineer or architect to physically inspect structural components (more than a reserve specialist reviewing photos and records), boards should expect costs to run higher than a traditional reserve study, often several thousand dollars more depending on building size, number of stories, and site access. Get at least two or three quotes from firms with Florida-licensed engineers who specifically reference SIRS scope of work under 718.112(2)(f)2, since pricing varies a lot by firm and region. A cheap, generic reserve study that doesn't meet the specific SIRS component list is a wasted expense. It can leave your board thinking you're covered when you're not, and you'll pay again for a compliant version. Get the scope of work in writing before signing anything, and confirm the report format matches what your management company and county will expect at renewal.
Are HOA special assessments tax deductible?
Generally, no. Special assessments paid to a homeowners' or condo association are treated by the IRS as a nondeductible personal expense in almost all cases, similar to how routine HOA dues aren't deductible for a primary residence [6]. The IRS has not issued a specific revenue ruling naming HOA special assessments, but its general guidance on nondeductible personal expenses (IRS Publication 530, for homeowners) treats association fees and assessments the same way it treats other costs of maintaining a personal residence: not deductible. There are narrow exceptions. If the unit is a rental property, special assessments may be deductible as a business expense, or in some cases must be capitalized and depreciated rather than deducted immediately, depending on whether the assessment is for a repair or a capital improvement [6]. If part of your home is used for a qualifying home office, a portion may be deductible under home-office rules. And if a special assessment is tied to a federally declared disaster and reimbursement isn't received from insurance, there can be a casualty loss angle worth discussing with a CPA. For a typical owner-occupied condo paying a special assessment to cover a SIRS-driven structural repair, don't count on a tax deduction. Talk to a tax professional about your specific situation, especially if the unit is a rental or mixed-use, since the capitalize-versus-deduct question gets technical fast.
What triggers a mandatory reserve study in Florida, and who has to get one?
Florida's SIRS mandate applies to condominium buildings that are three stories or more in height, per Fla. Stat. 718.112(2)(g) [1]. Buildings that reached their milestone inspection threshold (generally 30 years old, or 25 years old if within three miles of the coast, under Fla. Stat. 553.899) are the same population largely driving the SIRS timeline, though the two requirements are legally separate: milestone inspections check structural safety now, SIRS plans the money to fix what's found or what's coming. The statute set the first SIRS deadline for December 31, 2024, for existing condominium and cooperative associations, with the reserve funding requirements (no more waiving SIRS-covered items) kicking in for the budget adopted after that report is completed [1]. New buildings and newly created associations have their own phase-in timeline tied to their turnover date and age milestones. Smaller buildings (one and two stories) and single-family HOAs are outside the SIRS mandate. But every condo board, regardless of height, should confirm its status directly with legal counsel, because there are nuances around mixed-use buildings, phased developments, and associations that include both condo and non-condo structures on the same parcel. For the inspection side of this timeline, our milestone inspections coverage walks through the age and coastal triggers in detail.
What does a Structural Integrity Reserve Study actually have to cover?
A SIRS must inspect and fund, at minimum, these structural components: roof, load-bearing walls and other primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, and windows and exterior doors, plus any other item with a deferred maintenance expense or replacement cost exceeding $10,000 that would affect habitability if left unaddressed [1]. The report must be based on a visual inspection performed by a licensed engineer or architect, not a reserve specialist working from photos alone. The statute requires the study every 10 years after the building's creation, and the results must be distributed to unit owners and, in many cases, filed with the state through the association's annual reporting to DBPR [4]. This is where a lot of boards get tripped up: a financial reserve study your management company has been running for years, covering paint and paving, is not automatically a SIRS. If it wasn't performed by a licensed engineer or architect and doesn't hit every required structural component on the statutory list, it won't satisfy the mandate no matter how thorough it looks. Confirm with your engineer that the scope of work explicitly cites 718.112(2)(g) before you pay for it.
What happens if a board skips or delays the reserve study?
Skipping the SIRS isn't a paperwork technicality, it exposes the board to real liability and the association to real risk. Florida law makes the SIRS mandatory, not optional, for qualifying condo buildings, and DBPR has authority to investigate association compliance and impose penalties under Chapter 718 [4]. Beyond the regulatory risk, there's the practical risk: a board that doesn't know its true structural funding gap is a board flying blind into a special assessment it can't size correctly. Boards that get the study, budget honestly, and communicate early with owners tend to spread costs over years through planned contributions. Boards that skip it tend to discover the number all at once, usually right after a failed inspection or an insurance nonrenewal, which is the worst possible time to ask owners for tens of thousands of dollars each. Directors also carry personal exposure to consider. While Florida law provides some business-judgment protections for good-faith board decisions, ignoring a clear statutory requirement is a different category of risk than a disputed judgment call. Get counsel involved early if your association is behind on SIRS timing.
How does a board actually organize and schedule all this?
Between the milestone inspection deadline, the SIRS deadline, the annual budget vote, and the ordinary reserve study renewal cycle, a lot of Florida condo boards are juggling four or five overlapping compliance dates with volunteer time and a part-time property manager. The paperwork problem is often bigger than the engineering problem. This is the gap a $199 one-time Building-Specific Board Compliance Kit is built for (see the board-kit-builder): it organizes your building's specific milestone and SIRS deadlines by age and coastal zone, builds a communication timeline for owner notices, and tracks which reports are due when. It does not replace the licensed engineer, architect, or reserve specialist the statute requires, and it doesn't interpret your declaration or bylaws. Those calls stay with your professionals and counsel. What it does is keep a volunteer board from missing a filing date buried in a 40-page statute. Whatever tool or spreadsheet your board uses, the core discipline is the same: know your building's age and coastal distance, know your milestone inspection due date, know your SIRS due date, and put both on the calendar with enough lead time to bid the work properly instead of scrambling in the final quarter.
How should a board compare reserve study proposals from different firms?
Price alone is a bad way to choose a reserve study firm. The cheapest bid is often cheapest because it skips physical inspection of some components, relies on generic industry life-expectancy tables instead of your building's actual condition, or isn't scoped to meet the SIRS statutory list at all. Ask every firm for: the specific credentials of the engineer or architect who will do the physical inspection (license number, state of licensure), a written scope of work that names each SIRS-required component, the report format and delivery timeline, and references from other Florida condo boards of similar size and age. A legitimate firm should have no problem citing Fla. Stat. 718.112(2)(g) directly in their proposal. Get three quotes minimum. Compare more than the total price but what's actually inspected: does the proposal include roof penetration testing, or just a visual from the ground? Does it include a structural engineer's stamp, or just a reserve analyst's estimate? The gap between a real SIRS and a repackaged old-style reserve study is exactly where boards get burned, paying once for something that has to be redone.
Frequently asked questions
What is a reserve study?
A reserve study is a professional inspection and financial forecast that tells an association how much money it needs to save, and how fast, to replace major shared components like roofs, plumbing, and structural elements without hitting owners with a surprise bill. In Florida, condo buildings of three stories or more must get a structural version called a SIRS under Fla. Stat. 718.112.
What is a reserve study for an HOA?
For a homeowners' association, a reserve study inspects common-area assets like a clubhouse, pool, or private roads and builds a funding schedule for their eventual replacement. Unlike condos under Chapter 718, most HOAs under Chapter 720 aren't currently required by state law to get one; it's a voluntary but strongly recommended financial planning tool.
What is an HOA assessment?
An HOA assessment is the regular fee, usually monthly, that funds an association's operating budget and reserve contributions. A special assessment is a separate, one-time charge levied outside the regular budget, typically to cover an unexpected or underfunded expense like a structural repair or an insurance premium spike.
How much should an HOA have in reserves?
There's no single required dollar figure; it depends on your building's components and their replacement costs. Industry professionals often cite 70% of the fully-funded ideal balance as a healthy benchmark, while under 30% funded signals high special assessment risk. Florida law requires full funding (no waiving) specifically for SIRS structural components in qualifying condos.
How much does a reserve study cost?
A standard financial reserve study typically runs roughly $1,000 to $5,000 depending on property size and complexity, though there's no fixed statewide rate. Florida's mandatory Structural Integrity Reserve Study (SIRS), which requires a licensed engineer or architect, generally costs more than a standard study because of the physical inspection requirement. Get multiple quotes.
Are HOA special assessments tax deductible?
Generally no, for an owner-occupied primary residence. The IRS treats association assessments similarly to other nondeductible personal home-maintenance costs under its homeowner guidance. Exceptions can apply for rental properties or qualifying home offices, where the assessment may be deductible or must be capitalized and depreciated. Talk to a CPA about your specific situation.
What is the difference between a reserve study and a Structural Integrity Reserve Study (SIRS)?
A traditional reserve study covers a broad set of components (roofs, paint, paving) for funding planning purposes and doesn't require a specific license by statute. A SIRS is a Florida-mandated version for condos of three-plus stories, must be performed by a licensed engineer or architect, and covers a defined list of structural components with no funding waivers allowed.
Which Florida buildings must get a SIRS?
Condominium buildings three stories or higher must get a Structural Integrity Reserve Study under Fla. Stat. 718.112(2)(g). The first statutory deadline was December 31, 2024, with reserve funding requirements for SIRS-covered items applying starting with the next budget cycle after the report is completed.
Can a condo board still vote to waive reserve funding in Florida?
Not for SIRS-covered structural components. Since the post-Surfside legislative changes, associations can no longer waive or reduce funding for structural items like roof, load-bearing walls, floor, foundation, and waterproofing. Boards can still vote to waive or underfund non-structural reserve items like painting or landscaping.
How often does a reserve study need to be updated in Florida?
The statutory SIRS must be redone at least every 10 years per Fla. Stat. 718.112(2)(g). Many associations also run financial reserve study updates more frequently, often every 3 to 5 years, to keep replacement cost estimates current with inflation and material prices, even though that shorter cycle isn't a state mandate.
Who can legally perform a Florida SIRS?
The physical inspection portion of a Structural Integrity Reserve Study must be performed by a licensed engineer or architect, per Fla. Stat. 718.112(2)(g). A standard financial reserve study, by contrast, is commonly done by reserve specialists or management companies and doesn't carry the same licensing requirement under state law.
What happens if an association skips its required reserve study?
The association risks noncompliance with a Chapter 718 statutory mandate, potential DBPR inquiry, and, more practically, a board that has no accurate picture of its structural funding gap. That usually ends in a large, poorly-planned special assessment once a problem surfaces, rather than gradual, budgeted contributions over several years.
