TL;DR
A Florida condo reserve study typically costs $3,000 to $20,000 or more, depending on the number of components, building size, and whether it's a full study with site visit or an update. Most mid-size condos (30 to 100 units) pay somewhere between $5,000 and $12,000. Florida law under F.S. 718.112 now requires a structural integrity reserve study (SIRS) for buildings 3 stories and up.
What is a reserve study?
A reserve study is a professional analysis of a building's shared components (roof, paving, elevators, painting, plumbing risers, pool equipment, and under Florida's newer rules, structural elements) that estimates when each one needs replacement and how much that replacement will cost. The final report gives the board a funding schedule, essentially a savings plan, so the association isn't blindsided by a $2 million roof bill with no money set aside. A standard reserve study has two parts: a physical analysis (site visit, component inventory, condition assessment) and a financial analysis (current reserve balance, funding plan, contribution schedule). Some studies combine both every time; others do a full study once and then cheaper "update" studies in between. In Florida, there are now two related but distinct animals: the general reserve study that many associations have done for years as a budgeting tool, and the structural integrity reserve study (SIRS) that F.S. 718.112(2)(g) now requires for condominium buildings three stories or higher [1]. A SIRS covers a specific, statutorily defined list of structural components: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical, waterproofing, exterior painting, and windows/doors, among others [1]. A general reserve study can cover everything from carpet in the lobby to pool furniture. They're not automatically the same document, and a board should ask its provider directly which one it's getting.
What is a reserve study for an HOA?
For a homeowners association (as opposed to a condominium), a reserve study looks at the common elements the HOA itself owns and maintains: roads, clubhouse, pool, gates, drainage, community roofs if the HOA owns the buildings, and similar shared assets. The goal is identical to a condo study: figure out the remaining useful life of each component and build a funding plan so the HOA isn't forced into a surprise special assessment. Florida's SIRS mandate under F.S. 718.112 technically applies to condominiums and, through F.S. 720.30851, extends similar structural reserve study requirements to certain cooperative and homeowners' association buildings three stories or more [2]. Most single-family HOAs with no multi-story buildings won't trigger the structural version, but they still benefit from a standard reserve study, and many mortgage and insurance underwriters now expect to see one. The practical difference from a condo study is scope, not method. An HOA reserve study provider walks the property, inventories common-area assets, checks manufacturer life expectancy data and local condition, and produces the same style of 20 to 30 year funding table a condo would get.
How much does a reserve study cost?
| Small condo, no elevator | Under 20 units | $2,500 to $5,000 | |
|---|---|---|---|
| Mid-size condo | 50 to 150 units | $6,000 to $15,000 | |
| Large high-rise / coastal | 150+ units | $15,000 to $30,000+ | |
| Update study (no site visit) | Any size | $1,000 to $3,000 | These ranges are general market estimates based on typical provider quotes reported by industry sources and reserve specialists; get at least two or three quotes from licensed engineers or reserve specialists for your specific building before budgeting. If your building needs a SIRS, confirm with the provider whether the SIRS structural inspection is priced separately from the general reserve study, since many firms bill them as two line items. |
Most Florida condo and HOA reserve studies run $3,000 to $20,000, with the bulk of associations landing between $5,000 and $12,000 for a full study. The number that matters most is unit count and building complexity, more than square footage. A small condo (under 20 units, no elevator, simple flat roof) can often get a full study for $2,500 to $5,000. A mid-size building (50 to 150 units, elevators, parking structure, pool) typically pays $6,000 to $15,000. Large or high-rise coastal buildings with extensive structural components, multiple elevators, seawalls, and garages can run $15,000 to $30,000 or more, especially once the SIRS structural scope is layered on top of the general reserve study. Update studies (no new site visit, just refreshed numbers and inflation adjustments) are cheaper, often $1,000 to $3,000, and many providers recommend these every 2 to 3 years between full studies. The Community Associations Institute, a national trade group for community association management, notes that reserve study costs vary by region, provider, and scope, and that associations should expect ongoing costs for periodic updates, more than a one-time fee [3]. There's no statewide fee schedule and no state-set price cap in Florida; the market sets it, and pricing varies significantly by firm. | Building type | Typical unit count | Full study cost range |
What drives the price of a reserve study up or down?
Six things move the price more than anything else: unit count, number of components, building age, whether it's a full study or an update, whether a licensed engineer has to sign off (required for SIRS), and coastal exposure. Unit count and component count matter because the provider has to inventory and estimate life expectancy on each item. A building with one roof, one parking lot, and one pool is simpler to study than a sprawling complex with six roof sections, a marina, and three elevator banks. Building age matters because older buildings, especially those approaching the 25-year or 30-year milestone inspection window, often need more detailed structural review, and any deficiencies found during a milestone inspection can expand the scope (and cost) of the SIRS. Who signs the report matters a lot under Florida's SIRS rule. F.S. 718.112(2)(g) requires the SIRS to be based on a visual inspection performed by a licensed engineer or architect [1]. That licensing requirement pushes cost above what a general reserve study preparer (who doesn't always need an engineering license) might charge. Coastal exposure adds cost too. Buildings near salt water often need additional attention to corrosion, waterproofing, and seawall/dock components, and providers sometimes bring in specialty subconsultants for those items, which shows up in the invoice.
What is the difference between a reserve study and a SIRS?
A SIRS (structural integrity reserve study) is a specific, narrower, statutorily defined study focused only on structural components, required for Florida condo buildings three stories and higher under F.S. 718.112(2)(g) [1]. A general reserve study is broader and can include non-structural items like painting, landscaping equipment, and amenity furnishings, and isn't mandated by statute the same way. The statute lists exactly what a SIRS must cover: "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 exterior doors; and any additional structural component identified by the association's engineer or architect" [1]. It also requires the study to include a recommended reserve funding schedule with specific line-item components, not a single lump reserve figure. That's a change from older Florida practice, where boards could pool everything into one general reserve number. Associations often ask their reserve provider to do both in one engagement: the general study for budgeting on non-structural items, and the SIRS for the mandated structural list. That combined engagement usually costs more than either study alone but often less than two separate contracts with two separate firms. For a deeper look at exactly what a reserve study for a condo association needs to contain under the current statute, see our guide on reserve study for condo association.
How much should an HOA or condo have in reserves?
There's no single dollar figure that fits every building; the right reserve amount depends entirely on the age, size, and condition of your specific components, which is exactly why the reserve study exists instead of a flat rule. That said, funding is generally measured as a percentage of the "fully funded" ideal, meaning the reserve balance that would exist if every component's replacement cost were saved for exactly on schedule. CAI has historically noted that a reserve fund below roughly 30% funded is considered weak, and many reserve specialists treat 70% or higher as a healthy target, though there's no single universal industry benchmark or government-set percentage [3]. Florida law doesn't set a specific dollar reserve target either; instead, F.S. 718.112(2)(f) requires reserves to be funded based on the amount determined by a current reserve study (for the SIRS components, full funding based on the study's recommended amounts became the default after recent legislative changes, unless owners vote otherwise) [1]. Historically, Florida law allowed condo associations to vote to waive or reduce reserves for many items. Recent statutory amendments have tightened that ability specifically for the SIRS-covered structural components; boards should confirm current waiver rules with counsel since this area has changed more than once since 2022. For background on how the state's relief and phase-in provisions have shifted, see florida condo reserve fund relief. The honest answer for "how much should we have in reserves" is: get the study done, look at the recommended funding schedule for your specific roof, plumbing, and structural components, and fund toward that schedule rather than guessing at a round number.
What is an HOA assessment and how is it different from reserves?
An HOA assessment is a fee the association charges owners, either as a regular recurring payment (monthly or quarterly dues) or as a one-time special assessment for an unexpected or underfunded cost. Regular assessments typically fund operating expenses and reserve contributions together; special assessments happen when the association needs money faster than reserves and regular dues can provide it, often after storm damage, an inspection finding, or a funding shortfall. Reserves are the savings account; assessments are how the money gets collected, whether steadily over years (through regular dues that include a reserve line item) or all at once (through a special assessment). A well-funded reserve, built from a realistic study, is the main tool that keeps special assessments smaller and less frequent. Boards that skip or underfund reserve studies tend to be the ones hit hardest by large special assessments later, since the underlying cost of a new roof or repaired garage deck doesn't go away just because nobody planned for it. For more on how special assessments work and what triggers them, see hoa special assessment.
Are HOA special assessments tax deductible?
For most individual condo or HOA owners, a special assessment is generally not tax deductible if it's used for a capital improvement (like a new roof, structural repair, or major system replacement), because the IRS treats capital improvements as an addition to the cost basis of the property rather than a deductible expense. If the assessment covers routine repairs and maintenance on a rental property you own, it may be deductible as a rental expense; if it's your personal residence, it typically isn't deductible at all. The IRS explains the general capital improvement versus repair distinction in Publication 523 for home sale basis purposes, and rental property owners should check IRS Publication 527 for what counts as a deductible rental expense versus a capitalized improvement [4][5]. This is genuinely a tax question specific to your situation (rental vs. primary residence, size of assessment, what it funded), so don't treat a blog post, including this one, as tax advice. Talk to a CPA or tax preparer who can look at your specific assessment notice and property use.
Who actually performs a reserve study, and does it have to be an engineer?
A general reserve study is often performed by a reserve study specialist, who may or may not be a licensed engineer, depending on the firm and the scope of the study. A SIRS, however, must be based on a visual inspection performed by a licensed engineer or architect, per F.S. 718.112(2)(g) [1]. Florida's engineering and architecture licensing boards, operating under DBPR, regulate who can lawfully sign off on the visual inspection required for a SIRS; the Florida Board of Professional Engineers sets licensure standards under F.S. Chapter 471, and any engineer performing a SIRS inspection must hold an active Florida license under that chapter [6]. Boards should ask any reserve provider directly for their license number and confirm it's active, and should get the SIRS specifically performed or supervised by a Florida-licensed engineer or architect, since a study that skips this requirement could need to be redone. This is also where a milestone inspection report, if your building has had one, becomes useful: engineers preparing the SIRS often reference milestone inspection findings for buildings that have already gone through that separate 25/30-year structural inspection process.
How often does a reserve study need to be updated?
Most reserve specialists recommend a full reserve study every 5 years, with lighter update studies (using existing data adjusted for inflation and remaining life) every 2 to 3 years in between. Florida's SIRS specifically must be completed at least every 10 years, per F.S. 718.112(2)(g), though many associations choose to update sooner given how much material and labor costs have shifted since 2020. Boards shouldn't treat the reserve study as a one-and-done document. Costs change, components age faster or slower than expected, and after any major storm or insurance claim it's worth checking whether the funding schedule still matches reality. An outdated study is only marginally better than no study at all, since the numbers it produces stop reflecting current replacement costs.
How do boards actually budget for a reserve study and act on the results?
Once the study is in hand, the real work starts: comparing the recommended funding schedule against current reserve balances, deciding how much to raise dues or contributions, and documenting the decision for owners and future boards. This is often where volunteer boards get stuck, not because the numbers are hard to understand, but because organizing the paperwork, meeting minutes, owner notices, and follow-up deadlines across multiple statutory requirements (milestone inspection, SIRS, reserve funding votes) becomes its own project. A $199 one-time Building-Specific Board Compliance Kit (available through the board kit builder) doesn't replace the licensed engineer or reserve specialist who performs the study itself, but it does organize the resulting deadlines, schedule the required notices, and keep the compliance paperwork in one place so a volunteer board isn't tracking five overlapping statutory clocks by memory. The kit doesn't offer legal interpretation of a specific association's governing documents; boards should always confirm document-specific questions with counsel. For associations still early in the process, our guides on reserve study and hoa reserve study walk through the basic steps before you even get a quote.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment of a building's shared components (roof, elevators, plumbing, structural elements) that estimates remaining useful life and replacement cost, then produces a funding schedule so the association can save toward those future costs instead of facing a surprise bill or special assessment.
What is a reserve study for HOA?
For an HOA, a reserve study looks at community-owned assets like roads, clubhouses, pools, and (if applicable) shared buildings, estimating replacement timing and cost for each. It's the same method as a condo study, just applied to whatever common elements the HOA itself owns and maintains.
What is an HOA assessment?
An HOA assessment is a fee charged to owners, either recurring (regular dues covering operations and reserves) or one-time (a special assessment for an unplanned cost). Special assessments often happen when reserves fall short of an urgent repair or inspection finding.
How much should an HOA have in reserves?
There's no flat dollar figure; the right amount comes from a current reserve study specific to your building's components. Many reserve specialists consider funding below about 30% of the fully-funded ideal weak and 70%+ healthy, though there's no single official government benchmark [3].
How much does a reserve study cost?
Florida condo and HOA reserve studies typically cost $3,000 to $20,000, with most mid-size buildings paying $5,000 to $12,000 for a full study. Small, simple buildings can pay as little as $2,500; large high-rises with extensive structural scope can pay $30,000 or more.
Are HOA special assessments tax deductible?
Generally no, if the assessment funds a capital improvement on your primary residence; it typically adds to your property's cost basis instead. If it's a rental property and the assessment covers repairs, it may be deductible as a rental expense. Check IRS Publication 523 or 527, or ask a CPA [4][6].
What's the difference between a reserve study and a SIRS?
A SIRS is a Florida-specific, narrower study covering only structural components (roof, load-bearing walls, foundation, plumbing, electrical, waterproofing, and similar), required for condo buildings 3 stories or higher under F.S. 718.112(2)(g). A general reserve study covers a broader list of components and isn't mandated the same way.
Does a reserve study have to be done by a licensed engineer?
A general reserve study doesn't always require a licensed engineer, depending on the firm. A SIRS does: F.S. 718.112(2)(g) requires it be based on a visual inspection by a licensed engineer or architect.
How often does a reserve study need updating?
Most specialists recommend a full study every 5 years with lighter updates every 2 to 3 years between. Florida's SIRS specifically must be redone at least every 10 years under F.S. 718.112(2)(g), though many boards update sooner given rising material costs.
Is a reserve study required by Florida law?
Yes, for condominium buildings 3 stories or higher, a structural integrity reserve study (SIRS) is required under F.S. 718.112(2)(g). General reserve studies for non-structural components aren't independently mandated by the same statute, but funding decisions are increasingly tied to whatever study the association has completed.
What happens if a condo skips or delays its reserve study?
Skipping the required SIRS can leave a condo association out of compliance with F.S. 718.112, potentially exposing the board to owner disputes or complications during sale/financing, since lenders and title companies increasingly ask for SIRS status. Delaying a general reserve study just means budgeting is based on guesswork instead of data.
How much does a SIRS cost compared to a general reserve study?
A SIRS alone (structural components only) often runs comparable to or somewhat less than a full general reserve study, since it's narrower in scope, but because it requires a licensed engineer or architect, per-hour costs can be higher. Many firms bundle both into one engagement, which usually costs more total but less than hiring two separate firms.
