First condo reserve studies: what Florida boards need to know

Last updated 2026-08-14

what is a reserve study

A reserve study is a physical inspection plus a financial forecast. A qualified inspector walks the property, estimates the remaining useful life of major shared components (roof, paving, painting, plumbing, structure), and then a preparer builds a funding schedule showing how much money the association needs to save each year to replace those items when they wear out. Think of it as the building's version of a retirement plan. Instead of guessing how much to sock away, someone with training in construction and asset lifecycles does the math for you: this roof has 8 years left, it will cost roughly $400,000 to replace, so the association needs to be setting aside about $50,000 a year starting now. Most reserve studies have two parts. The physical analysis lists each reserve component, its estimated useful life, remaining useful life, and replacement cost. The financial analysis takes that data and models a funding plan, either "full funding" (aiming to have 100% of the theoretical reserve balance at all times) or a "baseline" or "threshold" approach that keeps the balance above zero but not fully funded. Florida's newer structural requirements push toward something closer to full funding for the specific structural items covered by law ^[1].

what is a reserve study for an hoa

For a homeowners association (as opposed to a condo), a reserve study covers whatever the HOA itself owns and maintains: private roads, community pools, clubhouse roofs, retention ponds, gates, and similar common elements. It works the same way as a condo study, physical inspection plus funding plan, but the required component list is different because single-family HOAs don't own building structures the way condos do. Florida does not currently impose the same structural integrity reserve study mandate on HOAs that it does on condominiums. The SIRS requirement in Fla. Stat. 718.112(2)(g) applies specifically to condominium associations with buildings three stories or more ^[1]. HOAs are still generally required to maintain reserves under Fla. Stat. 720.303(6), but the structural-inspection trigger tied to milestone inspections doesn't apply to typical single-family HOA developments, since those statutes (Fla. Stat. 553.899) are aimed at condo and cooperative buildings ^[2]. That said, plenty of HOA boards commission voluntary reserve studies anyway, because a 20-year-old clubhouse roof doesn't care what statute governs it. It's just good practice.

what is an hoa assessment

An assessment is money the association charges owners beyond (or instead of) their regular monthly dues, usually to cover a specific cost. There are two flavors: regular assessments (the routine monthly or quarterly fee that funds operating expenses and reserves) and special assessments (a one-time or short-term charge to cover something reserves didn't fully cover, like an unexpected roof failure or a court-ordered structural repair). When people ask "what are hoa assessments" they usually mean the special kind, because that's the one that shows up as a surprise five-figure bill in the mailbox. Special assessments happen when the reserve study underestimated a cost, when the board deferred saving for years, when insurance doesn't cover storm damage in full, or when a new law (like Florida's SIRS mandate) forces spending nobody budgeted for. Governing documents typically set rules for how big a special assessment can be before it needs a membership vote. Those percentage thresholds and notice requirements vary by association, so ask your association's counsel to confirm what your declaration actually says before assuming a board can levy any amount it wants.

how much should an hoa have in reserves

There's no single dollar figure that applies to every building. Reserve adequacy depends on the property's age, size, climate exposure, and how many big-ticket items are approaching end of life at once. Instead of a flat number, look at percent funded: the ratio of what's actually in the reserve account to what the reserve study says the account should theoretically hold if every component were funded proportional to its used-up life. Industry-side data from the Community Associations Institute and reserve study firms commonly cites buildings under 30% funded as being at meaningfully higher risk of a special assessment or deferred maintenance crisis, though there's no single federal or Florida statutory threshold that defines "adequate" funding as a specific percentage ^[3]. Florida's newer law sidesteps the percentage debate for the structural items specifically: as of the reserve study and funding requirements tied to 718.112, associations must fund reserves for SIRS-covered components based on the study's findings, and boards can no longer vote to waive or reduce those specific structural reserves ^[1]. For everything outside the structural SIRS components (things like painting, paving, pool equipment), Florida law still generally allows a membership vote to waive or reduce reserve funding, so "how much should we have" for those items remains partly a board and membership decision, guided by the study's recommendation. Confirm current waiver rules with your association's counsel, because this area of Florida condo law has changed multiple times since 2022 and may change again.

how much does a reserve study cost

Building size	Small (under 50 units)	Large high-rise (200+ units)
Scope	Update to existing study	First-ever full study
Structural inspection	Not required (non-SIRS building)	Required (3+ stories, SIRS)
Site complexity	Single building, simple systems	Multiple buildings, seawalls, garages
Coastal exposure	Inland, minimal corrosion risk	Coastal, salt air, higher inspection detail	Boards should get at least two or three quotes and confirm the preparer's credentials. Florida's Department of Business and Professional Regulation (DBPR) oversees community association management licensing and can confirm whether a manager or firm is properly licensed.

Cost depends heavily on building size, number of components, and whether a licensed engineer needs to physically inspect structural elements (required for the SIRS portion) versus a general reserve specialist estimating replacement costs for non-structural items. Rough ranges reported by reserve study firms and cited in condo association trade publications run from about $3,000 for a small, straightforward association up to $20,000 or more for a large high-rise with a complex structural scope ^[4]. The SIRS-specific inspection, since it requires a licensed engineer or architect under Fla. Stat. 718.112(2)(g), often costs more than a traditional "soft" reserve study did in years past, because you're paying for a structural professional's time and liability, more than a reserve consultant's spreadsheet work. Here's a rough breakdown of what drives the price: | Factor | Lower cost | Higher cost |

what does a florida SIRS actually require, and who has to get one

A Structural Integrity Reserve Study (SIRS) is Florida's specific, statutory version of a reserve study, required for condominium buildings three stories or more in height. It must be performed at least once every 10 years, and it has to cover a defined list of structural and life-safety components: roof, load-bearing walls and other primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, windows, and any other item that the study preparer determines has a deferred maintenance expense or replacement cost exceeding $10,000 and would affect habitability if left unaddressed ^[1]. The law requires the SIRS to be performed by a licensed engineer or architect, per Fla. Stat. 718.112(2)(g). Associations that reached their certificate of occupancy threshold on or before December 31, 2024 have that deadline; buildings hitting the 30-year mark (or 25 years for coastal buildings, per local requirements) after that continue on their own timelines. Confirm your building's exact SIRS deadline with your association's counsel and your county building department, since the December 31, 2024 date already passed for many buildings and the compliance landscape (extensions, local ordinance changes) has shifted more than once. Once the SIRS is done, associations must include the fully funded reserve amounts for those structural items in the annual budget, and starting with the fiscal year following the SIRS, owners can no longer vote to waive or reduce reserve funding for those specific components ^[1]. This is the single biggest financial shift in Florida condo law in a generation for a lot of buildings, because reserves that used to be optional (or token line items) are now mandatory.

what is a milestone inspection and how is it different from a reserve study

A milestone inspection is a structural safety inspection, not a financial planning document. Fla. Stat. 553.899 requires condo and cooperative buildings three stories or more to undergo a milestone inspection by a licensed architect or engineer, generally at 30 years from certificate of occupancy (25 years if the building is within three miles of a coastline), and every 10 years after that ^[2]. A reserve study (including the SIRS) uses information about the building's condition, sometimes drawing on milestone inspection findings, to build a funding plan. The milestone inspection asks "is this building structurally sound right now," while the SIRS asks "how much money do we need to save so we can keep it sound going forward." Boards often schedule them close together since a structural engineer is already on site, but they're legally distinct requirements with separate statutory triggers. For a fuller breakdown of milestone timing rules, see our guide on reserve studies for condo associations.

are hoa special assessments tax deductible

Generally, no, not for the individual owner's personal income taxes, and not in the way most owners hope. Special assessments used for capital improvements to a personal residence (like a new roof levied through the HOA) are typically treated as an addition to your cost basis in the property, which can reduce capital gains tax when you sell, rather than as an immediate deduction ^[5]. There are narrow exceptions. If the unit is a rental property, a portion of special assessment costs may be deductible as a business expense or depreciated over time, similar to any other capital improvement to rental real estate, per general IRS rules on rental property expenses ^[6]. If part of the assessment funds casualty-loss repairs tied to a federally declared disaster, there may be additional tax treatment to explore. This is genuinely a tax question, not a condo law question, and the right answer depends on your personal tax situation, whether the unit is owner-occupied or a rental, and how the association characterizes the assessment. Talk to a CPA before assuming either way. Don't take a board member's word for it, and don't take this article's word for it either; ask a tax professional who can see your specific numbers.

how do reserve studies interact with special assessments and insurance

A good reserve study is the single best tool a board has for avoiding a special assessment, or at least shrinking one. If the study says the roof needs replacing in six years at a cost of $600,000, and the board actually funds that number annually, owners write a slightly bigger reserve check each month instead of a five-figure surprise assessment later. The reverse is also true: buildings that skipped or lowballed reserve studies for years are exactly the ones now facing six-figure special assessments to catch up on SIRS-mandated structural reserves. If your building is facing one of these, our guide to HOA special assessments walks through notice requirements and payment plan options, and condo special assessment insurance covers what limited insurance products exist to help owners spread out a hit. Separately, some Florida associations have looked at reserve fund relief options the legislature has floated or passed in response to sticker shock from SIRS compliance costs. These have changed more than once since 2023, so don't assume any relief provision you read about last year is still in effect; check current statute language and ask counsel.

who actually performs a reserve study, and how do boards pick one

For the structural SIRS portion, Florida law requires a licensed engineer or architect ^[1]. For the broader financial reserve study (the non-structural components like paint, paving, and pool equipment), many associations use a reserve study specialist, sometimes credentialed through organizations like the Community Associations Institute, though Florida doesn't license "reserve study preparer" as its own profession the way it licenses engineers. Boards should confirm any engineer or architect performing the SIRS is properly licensed through Florida's Department of Business and Professional Regulation, which maintains license lookup tools for regulated professions. Ask for the preparer's license number, ask to see a sample report from a similar-sized building, and get a written scope of work before signing. A vague one-page proposal is a red flag; a real SIRS or reserve study proposal should name the specific components being inspected and the deliverable format. This is also where a lot of boards get overwhelmed, not by the inspection itself but by everything that has to happen around it: scheduling the engineer, notifying owners, updating the budget, documenting board votes on reserve funding, and keeping records for the next 10-year cycle. That's the exact gap our $199 Building-Specific Board Compliance Kit is built to close: it doesn't replace the licensed engineer who has to do the actual SIRS or milestone inspection, but it organizes your building's deadlines, keeps required documents in one place, and helps you communicate the timeline to owners so nothing falls through the cracks between the study and the next board election.

what happens if a board just doesn't do the reserve study

Skipping a legally required SIRS isn't a quiet cost-saving move, it's a compliance failure with real consequences. Associations that fail to complete a required SIRS can face enforcement action, and boards that ignore the underlying structural risk can face liability if a preventable failure occurs, separate from any statutory penalty. Beyond the legal exposure, skipping the study just delays the math. The building still needs a new roof in ten years whether or not anyone studied it. Delaying only means less time to save, which usually means a bigger special assessment when the bill finally comes due, or worse, a building that can't get affordable insurance because underwriters increasingly ask for milestone and SIRS documentation before writing a policy. If your board is behind, the honest first move is not panic, it's sequencing: get the milestone inspection scheduled if it's overdue, get the SIRS scheduled (they can sometimes be coordinated with the same engineering firm), and get a preliminary reserve number in front of owners before the annual budget meeting so nobody is blindsided. Boards that communicate early tend to get less pushback than boards that spring a number on owners at the last minute.

Frequently asked questions

What is a reserve study?

A reserve study is a professional inspection and financial forecast for a community association's major shared components, roof, structure, plumbing, paving, and similar systems. It estimates each component's remaining useful life and replacement cost, then builds a funding schedule showing how much the association should save each year so it has the money when repairs come due, instead of hitting owners with a surprise special assessment.

What is a reserve study for an HOA?

For an HOA, a reserve study covers whatever common property the association owns: private roads, clubhouse, pool, gates, drainage systems. It works like a condo reserve study, but Florida's structural integrity reserve study (SIRS) mandate under Fla. Stat. 718.112 applies specifically to condominium buildings three stories or more, not typical single-family HOA developments.

What is an HOA assessment?

An assessment is a fee an association charges owners. Regular assessments fund routine operating costs and reserves. Special assessments are one-time or short-term charges levied when reserves don't cover a cost, like an emergency roof repair or a SIRS-driven reserve shortfall. Governing documents typically set notice rules and vote thresholds for special assessments above certain amounts; check your declaration with counsel.

How much should an HOA have in reserves?

There's no single dollar figure that fits every property. Reserve adequacy is usually measured as percent funded, actual reserve balance versus the theoretical fully funded balance from the reserve study. Industry sources commonly flag under 30% funded as higher risk, though Florida law doesn't set a universal percentage requirement outside the mandatory SIRS structural components.

How much does a reserve study cost?

Reserve study costs commonly range from about $3,000 for a small, simple association up to $20,000 or more for a large high-rise with a complex structural scope, according to figures reported by reserve study firms. Florida's SIRS inspection, which requires a licensed engineer or architect, often costs more than a traditional non-structural reserve study.

Are HOA special assessments tax deductible?

Generally not as a direct deduction on personal income taxes. Special assessments for capital improvements to an owner-occupied home typically add to your cost basis instead, which can reduce capital gains tax when you sell. Rental property owners may have different treatment. Talk to a CPA about your specific situation before assuming either way.

What's the difference between a reserve study and a milestone inspection?

A milestone inspection (Fla. Stat. 553.899) is a structural safety check confirming a building is currently sound, required at 30 years (25 if within three miles of the coast) and every 10 years after. A reserve study, including Florida's SIRS, is a financial planning document that estimates future repair costs and sets a savings schedule for those components.

Who has to get a SIRS in Florida?

Condominium associations with buildings three stories or more must obtain a Structural Integrity Reserve Study at least every 10 years under Fla. Stat. 718.112(2)(g). It must be performed by a licensed engineer or architect and cover components like roof, load-bearing structure, plumbing, electrical, and waterproofing.

Can a Florida condo association waive reserve funding after a SIRS?

No, not for the structural components identified in the SIRS. Once a SIRS is completed, associations must fund full reserves for those specific structural items, and members can no longer vote to waive or reduce that funding. Non-structural reserve items outside the SIRS scope may still be subject to waiver votes; confirm current rules with counsel since this has changed since 2022.

What happens if a Florida condo board skips a required SIRS?

Skipping a legally required SIRS exposes the association to enforcement action and leaves the board without the documentation insurers and lenders increasingly require. It also just delays the underlying math: the building still needs the repairs, and waiting typically shrinks the savings window and increases the size of the eventual special assessment.

Does a reserve study cover HOA common areas like pools and clubhouses?

Yes. A reserve study for an HOA typically inventories every major common-area component the association owns and maintains, pools, clubhouse roofs and HVAC, playground equipment, private roads, retention ponds, and estimates remaining life and replacement cost for each one to build a savings schedule.

How often does Florida require a reserve study or SIRS update?

The SIRS must be performed at least once every 10 years under Fla. Stat. 718.112(2)(g). Milestone structural inspections follow a separate 10-year cycle after the initial inspection at 30 years (or 25 years for coastal buildings) under Fla. Stat. 553.899. Some associations choose to update non-structural reserve studies more frequently, every 3 to 5 years, as a budgeting best practice.
