TL;DR
A reserve study is a professional assessment of a building's common elements and the money needed to repair or replace them on schedule. Florida condos 3+ stories must get a Structural Integrity Reserve Study (SIRS) at least every 10 years under Fla. Stat. 718.112, and boards can no longer waive reserves for the items that study covers.
what is a reserve study
A reserve study is a written report, usually done by an engineer or a specialized reserve study firm, that looks at the major common elements of a building (roof, paint, pavement, structural components, plumbing risers, elevators) and answers two questions: how much longer will this thing last, and how much will it cost to fix or replace when it fails. A good reserve study has two parts. The physical analysis inspects the components and estimates remaining useful life. The financial analysis takes that data and builds a funding plan, usually a 20 to 30 year table showing what the association should be contributing to reserves each year so it has cash on hand when the roof actually needs replacing instead of scrambling for a special assessment. For Florida condominiums, this isn't just a good-governance idea anymore. Fla. Stat. 718.112(2)(g) requires a specific version called a Structural Integrity Reserve Study (SIRS) for buildings three stories or more, covering items like the roof, load-bearing walls, floor, foundation, fireproofing, plumbing, and electrical systems [1]. The statute defines a SIRS as "a study of the reserve funds required for future major repairs and replacement of the common areas" based on a visual inspection [1].
what is a reserve study for hoa
Homeowners' associations (single-family and townhome HOAs, not condos) are a different animal under Florida law. Chapter 720 governs HOAs, and as of now there is no statewide mandatory SIRS requirement for HOAs the way there is for condos under Chapter 718. That said, most well-run HOAs still commission reserve studies voluntarily, because the underlying math doesn't care what statute applies to you. Roads, retention ponds, clubhouse roofs, pool decks, and irrigation systems all wear out on predictable schedules. An HOA reserve study looks the same as a condo one: physical inspection, remaining useful life estimates, and a funding schedule. If your HOA's governing documents (declaration, bylaws) require reserves or a study, that document controls, more than the statute. Boards should have counsel review the declaration before assuming a study is optional. See our HOA reserve study guide for how HOAs typically approach this even without a statewide mandate.
how much does a reserve study cost
| Basic financial reserve study | Funding schedule only, no engineer site visit | $1,500-$3,500 | |
|---|---|---|---|
| Full reserve study (physical + financial) | Site inspection, component list, funding plan | $3,000-$6,000 | |
| SIRS (statutory, 3+ stories) | Licensed engineer/architect inspection of structural elements per 718.112(2)(g) | $5,000-$15,000+ depending on size | *Ranges are general market estimates, not a state fee schedule. Confirm current pricing with licensed firms in your area. |
Cost depends heavily on building size, number of components, and whether you need a full SIRS (which by statute must be done by a licensed engineer or architect, per Fla. Stat. 718.112(2)(g)2 [1]) versus a simpler financial-only reserve study. Industry sources and reserve study firms commonly cite a range of roughly $3,000 to $6,000 for a basic reserve study on a small-to-mid condo, and higher for larger buildings with more structural components to inspect (elevators, seawalls, multiple parking structures). A full SIRS with a licensed engineer inspecting structural elements tends to run higher than a traditional financial-only reserve study because of the additional site inspection and professional liability involved. There's no single statewide fee schedule; DBPR's condominium division licenses community association managers and fields owner complaints, but it does not publish reserve study pricing [2]. The honest answer is: get three quotes from firms that specifically do Florida SIRS work, because pricing varies by region, building height, and how much documentation (as-built drawings, prior inspection reports) you can hand the engineer up front. Buildings that make the engineer dig for information usually pay more. | Study type | Typical scope | Rough cost range* |
what is an hoa assessment
An HOA assessment is money the association charges owners to fund operations and reserves, separate from any mortgage or property tax payment. There are two basic kinds: regular assessments (routine monthly or quarterly dues) and special assessments (one-time charges for something the regular budget didn't cover). Regular assessments fund day-to-day operating costs (landscaping, management fees, insurance premiums) and, ideally, reserve contributions for future big-ticket repairs. Special assessments show up when reserves fall short of an actual repair bill, when an emergency happens (storm damage, a burst pipe, a failed structural inspection), or when the board simply didn't fund reserves adequately for years and the bill finally comes due. For condos specifically, Fla. Stat. 718.116 governs how assessments are levied and collected, and 718.112 governs the reserve funding requirements that drive how big those regular assessments need to be. For a deeper look at when and how special assessments get triggered, see HOA special assessment.
what are hoa assessments (regular vs special, in practice)
In practice, boards use assessments as their only real funding lever; there's no other revenue source. Get the reserve numbers wrong for a decade and the special assessment that follows can be brutal, sometimes tens of thousands of dollars per unit for roof, structural, or plumbing risers work. This is exactly the dynamic that pushed Florida to overhaul condo law after the Surfside collapse in 2021. Legislators wanted associations funding reserves proactively through regular assessments rather than discovering a six-figure structural bill and hitting owners with a special assessment they can't pay. A few owners genuinely can't absorb a large special assessment, which is why some legislators pushed relief measures allowing phased payment plans or partial delays under specific conditions. See florida condo reserve fund relief for how that relief mechanism works and who qualifies.
how much should an hoa have in reserves
There's no single dollar figure that's "enough," because the right reserve balance depends entirely on what components you own, their age, and their replacement cost. A reserve study is the only reliable way to answer this for your specific building; generic percentage rules (like "keep 10% of the annual budget in reserves") are not a substitute and can leave a building dangerously underfunded. What Florida law now requires, for condos 3+ stories, is full funding of reserves for the items covered by the SIRS, with no more ability for the membership to vote to waive or reduce those specific reserves. Fla. Stat. 718.112(2)(f)3 states that reserves for items included in a SIRS "may not be waived or reduced" after the association's turnover control period ends and after the first SIRS is completed [1]. The practical target most reserve professionals recommend is funding to somewhere between 70% and 100% of the study's calculated "fully funded" level, meaning your reserve balance closely tracks the theoretical value of the deterioration that's already happened on each component. Anything meaningfully below that (some studies flag under 30% funded as a red flag) signals a special assessment is probably coming.
what does a milestone inspection have to do with reserves
A milestone inspection and a SIRS are two different but related requirements that often get confused. A milestone inspection under Fla. Stat. 553.899 is a structural safety inspection of the building itself, required at 30 years after the certificate of occupancy (25 years if within three miles of the coast), and every 10 years after that [3]. A SIRS, by contrast, is the reserve funding study under 718.112 that determines how much money the association needs to save for future repairs to structural and other major components [1]. They're often performed close in time, and the milestone inspection report frequently informs what the SIRS engineer flags as needing reserve funding, but they are legally separate deliverables with separate statutory triggers. Boards juggling both deadlines in the same year (a common situation for buildings hitting their 30-year mark) often find it useful to track them on one calendar rather than two, since missing either deadline carries real consequences, including potential unsafe structure declarations by the local building official under the milestone inspection statute [3]. For more on the inspection side specifically, see reserve study for condo association.
are hoa special assessments tax deductible
Generally, no, not for the individual owner's personal residence. The IRS treats special assessments the same way it treats regular HOA dues for a personal-use property: they are not deductible as a personal expense, because they're considered a personal, capital-in-nature payment toward maintaining or improving your own property, similar to a home improvement rather than a deductible tax or interest payment. There are narrow exceptions. If the unit is a rental property, special assessments may be deductible as a business expense or added to the property's basis and depreciated, depending on whether the assessment is for a repair or a capital improvement. IRS Publication 527, which covers residential rental property, addresses how repair versus improvement costs get treated for rentals, and that same repair-versus-improvement distinction is what a CPA will apply to a rental unit's special assessment [4]. If part of your home is used exclusively for a home office, a proportional share might be deductible as a business expense. This isn't tax advice, and the right treatment depends on your specific facts (rental use, home office use, whether the assessment funds a capital improvement versus a repair). Talk to a CPA who handles real estate before you assume anything is deductible.
who has to get a reserve study or sirs done in florida
Under current Florida law, condominium associations with buildings three stories or higher must have a licensed engineer or architect complete a SIRS, and must do so at least once every 10 years, per Fla. Stat. 718.112(2)(g) [1]. This applies regardless of the building's age; a brand-new 3-story condo still needs one on the statutory clock. Cooperatives face similar requirements under Fla. Stat. 719.106, which incorporates parallel reserve and structural integrity provisions for co-ops [5]. HOAs under Chapter 720 are not currently subject to a statewide SIRS mandate, though this is an area the legislature has revisited before and could revisit again; boards should not assume the current rule is permanent. Associations that fail to complete a required SIRS or that improperly waive reserves covered by one risk complaints to DBPR's Division of Florida Condominiums, Timeshares, and Mobile Homes, which licenses and regulates community association managers and handles condo association complaints [2]. Confirm current deadlines and any transition provisions with your association's counsel, since the legislature has amended these deadlines more than once since 2022.
how do boards actually use a reserve study once it's done
The report itself doesn't do anything sitting in a filing cabinet. The board has to translate the study's recommended funding schedule into the annual budget, present it to owners at the budget meeting, and then actually follow through year after year, which is where a lot of associations fall down. The common failure mode: a board gets a reserve study, sees a scary number, and then either underfunds anyway (hoping to kick the can) or funds it for one year and lets discipline slip once board turnover happens. A study is only as good as the association's willingness to actually collect and hold the money. This is where organizing the paperwork matters more than people expect. Boards juggling a SIRS deadline, a milestone inspection deadline, and annual budget meetings often lose track of which document does what and when the next update is due. A $199 one-time Board Compliance Kit exists for exactly this problem: it organizes your building's specific deadlines (SIRS renewal, milestone inspection windows, reserve funding line items) into one schedule and helps you communicate the numbers to owners, though the actual study still has to be performed by the licensed engineer or reserve specialist the statute requires.
what happens if a reserve study finds a big shortfall
If the study shows reserves are significantly underfunded relative to upcoming repair costs, the board has a few real options, and none of them are painless. It can raise regular assessments gradually to catch up over several years, levy a special assessment to cover the immediate gap, pursue a loan (many banks and credit unions now offer condo association reserve/repair loans), or some combination of all three. What the board can no longer do, for SIRS-covered items in a condo association past its developer turnover, is vote to waive or underfund those specific reserves; Fla. Stat. 718.112(2)(f)3 closed that door for structural and other SIRS components [1]. Non-SIRS reserve items may still be subject to waiver votes depending on the association's documents and the specific statutory provision, so this is genuinely a point to run past counsel rather than assume. Boards that get ahead of a shortfall, communicating early and spreading the increase over two or three budget cycles, generally get far less pushback from owners than boards that sit on bad news and then drop a surprise assessment. Owners forgive being told hard news early. They do not forgive being blindsided.
Frequently asked questions
what is a reserve study
A reserve study is a professional report that inspects a building's major common elements (roof, structure, plumbing, elevators) and estimates how much money the association needs to save to repair or replace each one on schedule. In Florida, condos 3+ stories must get a specific version called a SIRS at least every 10 years under Fla. Stat. 718.112.
what is a reserve study for hoa
For HOAs (governed by Chapter 720, not condo law), a reserve study works the same way but there's currently no statewide mandate requiring one, unlike condos. Many HOAs still commission them voluntarily to plan for roads, clubhouses, pools, and other shared assets, and some governing documents require it independently of state law.
what is an hoa assessment
An HOA assessment is a charge the association levies on owners to fund operations and repairs. Regular assessments are recurring dues; special assessments are one-time charges, usually triggered when reserves fall short of an actual repair bill or an emergency repair comes up unexpectedly.
what are hoa assessments used for
Assessments fund everything from landscaping and insurance to reserve contributions for future roof, paving, and structural work. For condos, Fla. Stat. 718.116 governs how assessments are levied, while 718.112 sets the reserve funding requirements that drive how large regular assessments need to be to stay ahead of major repairs.
how much should an hoa have in reserves
There's no universal dollar figure; it depends on your specific components' age and replacement cost, which is exactly what a reserve study calculates. Many reserve professionals target 70% to 100% of the study's "fully funded" benchmark, and balances under roughly 30% funded are commonly treated as a red flag for an upcoming special assessment.
how much does a reserve study cost
Basic financial-only reserve studies commonly run $1,500 to $3,500. Full studies with a physical inspection and engineer involvement often run $3,000 to $6,000, and a statutory SIRS on a larger condo with a licensed engineer can run $5,000 to $15,000 or more depending on building size and complexity. Get multiple quotes; pricing varies by region.
are hoa special assessments tax deductible
Generally no, for a personal residence. The IRS treats special assessments like home improvement costs, not deductible personal expenses. Exceptions exist for rental properties (may be deductible or added to basis, per IRS Publication 527's repair-versus-improvement rules) or a home office used exclusively for business. Talk to a CPA about your specific situation.
what is a sirs and how is it different from a reserve study
A SIRS (Structural Integrity Reserve Study) is Florida's statutory version of a reserve study, required for condos 3+ stories under Fla. Stat. 718.112(2)(g), performed by a licensed engineer or architect, covering specific structural items like the roof, load-bearing walls, and foundation, done at least every 10 years.
who is required to complete a florida SIRS inspection
A licensed engineer or architect must perform the SIRS site inspection and prepare the report, per Fla. Stat. 718.112(2)(g)2. The board cannot self-certify this or use an unlicensed inspector; it has to be someone licensed in Florida to do structural or engineering assessments.
can a condo association waive reserves after a SIRS is done
No, not for items covered by the SIRS. Fla. Stat. 718.112(2)(f)3 states reserves for SIRS-covered components may not be waived or reduced once the developer turnover period ends and the first SIRS is complete. Non-SIRS reserve items may still be subject to waiver depending on your governing documents.
how often does a reserve study need to be updated
Florida's statutory SIRS must be done at least every 10 years per Fla. Stat. 718.112(2)(g). Many reserve professionals recommend a full update every 3 to 5 years and a lighter review annually, since costs and component conditions change faster than the statutory minimum assumes.
what's the difference between a milestone inspection and a reserve study
A milestone inspection (Fla. Stat. 553.899) is a structural safety check required at 30 years post-CO (25 if within 3 miles of the coast) and every 10 years after. A reserve study/SIRS (Fla. Stat. 718.112) is a financial planning document estimating reserve funding needs. They're related but legally separate requirements.
