HOA reserve study companies: what they do and cost

Last updated 2026-07-24

What is a reserve study?

A reserve study is a physical inspection and financial forecast of an association's common-area components, the roof, pool, paving, elevators, siding, and structural elements, paired with a schedule of when each will need repair or replacement and how much that will cost. The report gives boards two things at once: an engineering assessment of remaining useful life, and a funding plan that spreads the cost over years instead of hitting owners with a surprise bill. 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 then models how much the association needs to set aside annually, using either a "full funding" approach (reserves match 100% of the theoretical deficiency) or a "baseline" approach (reserves never hit zero). Community association trade groups generally recommend updating a full study every 3 to 5 years, with a shorter update or "reserve study review" in between years when nothing major has changed. In Florida, the term has picked up a second, narrower meaning since 2022. A Structural Integrity Reserve Study (SIRS) is a specific statutory requirement for condo and cooperative buildings three stories or higher, covering a defined list of structural components, and it must be performed by a licensed engineer or architect, not a generalist reserve specialist. See our reserve study explainer for the full mechanics of that requirement.

What is a reserve study for HOA properties specifically?

For a homeowners association (as opposed to a condo), a reserve study for HOA reserves usually covers amenities and infrastructure the HOA itself owns and maintains: clubhouse, pool, gates, private roads, retention ponds, playgrounds, and sometimes roofs if the HOA insures them. It does not typically cover the structural components of individual homes, since those belong to the homeowner. Florida's SIRS mandate under Fla. Stat. 718.112 applies to condominium and cooperative associations, not to typical single-family HOAs. That said, plenty of Florida HOAs voluntarily commission reserve studies because Fla. Stat. 720.303 requires HOAs with an annual budget over a certain threshold to either fund reserves for items over $10,000 or get a member vote to waive or reduce that funding. Without a study, the board is guessing at replacement costs and useful life, which is a bad way to run a multimillion-dollar asset. HOA reserve studies are usually less regulated in scope than condo SIRS work. A reserve specialist without an engineering license can legally perform one for most HOA common elements, though buildings with structural or life-safety systems (elevators, parking structures, seawalls) benefit from an engineer's involvement regardless of what the statute technically requires.

What is an HOA assessment, and what are HOA assessments used for?

An HOA assessment is a fee the association charges owners, separate from (or in addition to) regular dues, to cover a specific cost. "What is hoa assessment" and "what are hoa assessments" both point to the same basic idea: it's money the board levies against unit or home owners under authority granted in the governing documents and state statute. There are two main types. Regular assessments are the recurring monthly or annual dues that fund operating expenses and reserve contributions. Special assessments are one-time or limited-duration charges levied when reserves fall short of an actual repair cost, when an emergency repair comes up, or when a big capital project (like a SIRS-driven structural repair) needs funding faster than reserves alone can provide. Florida condo associations get their assessment authority from Fla. Stat. 718.116, which states that assessments are the liability of the unit owner and become a lien on the unit if unpaid. HOAs operate under a parallel framework in chapter 720. For background on how special assessments get triggered and structured, see hoa special assessment.

How much should an HOA have in reserves?

There's no single dollar figure that works for every HOA, because it depends entirely on the age, size, and component list of the property. The honest answer is: enough to cover the full replacement cost of every major common-area component, spread across its remaining useful life, without needing a special assessment for routine wear. A rough industry benchmark used by reserve specialists (not a legal standard) is that a "fully funded" reserve should sit near 70% or higher of what a full study says the association theoretically needs at that point in each component's life cycle. Associations funded below roughly 30% of that benchmark are often flagged in the reserve industry as "at risk" for a special assessment. These aren't statutory numbers, just common industry heuristics used by reserve specialist firms. For Florida condos specifically, the SIRS requirement changes the math. Fla. Stat. 718.112(2)(f) prohibits condo boards from waiving or reducing reserve funding for the structural components covered by a SIRS, starting with the funding cycle after the study is completed, for associations required to have one. That means the old practice of voting every year to keep reserves at bare minimum no longer works for buildings covered by the law. Boards should read florida condo reserve fund relief for the narrow relief options the legislature has carved out for hardship cases.

How much does a reserve study cost?

HOA reserve study (non-structural)	$1,500 - $6,000	Reserve specialist, sometimes engineer
Full reserve study, large condo	$5,000 - $20,000+	Reserve specialist or engineering firm
Florida SIRS (3+ story condo)	$3,000 - $15,000+	Licensed engineer or architect only
Milestone inspection (separate requirement)	Often $8,000 - $30,000+	Licensed engineer or architect	Boards often confuse SIRS with the milestone inspection requirement, but they're separate statutes with separate deliverables, and pricing for each is set independently by the firm you hire.

Reserve study costs vary by property size, number of components, and whether it's a full study or an update. Rough national ranges reported by reserve providers run from about $1,500 to $3,500 for a small HOA update, and $5,000 to $20,000+ for a full study on a large condo high-rise with many structural and mechanical systems. Florida's SIRS requirement adds cost because it must be done by a licensed engineer or architect rather than a general reserve consultant, and it requires a physical inspection of specific structural components (roof, load-bearing walls, primary structural members, floor, foundation, fireproofing, electrical, plumbing, waterproofing, exterior painting, windows, and for buildings that qualify, pavement and drainage) ^[1]. Engineering firms performing SIRS work in Florida commonly quote in the $3,000 to $15,000+ range for a typical mid-rise, with larger or more complex buildings running higher. There's no statewide fee schedule; costs depend on square footage, number of buildings, and travel. | Study type | Typical cost range | Who performs it |

How do I choose an HOA or condo reserve study company?

Start with licensing. If your association is a Florida condo or co-op three stories or higher, your SIRS must be performed by a person qualified to perform such studies, defined by statute as a licensed engineer or licensed architect ^[1]. For non-SIRS reserve studies covering HOA amenities, look for credentials from national reserve organizations; the most common are the Reserve Specialist (RS) designation and the Professional Reserve Analyst (PRA) designation from the Association of Professional Reserve Analysts. Check the license directly. Florida's Department of Business and Professional Regulation (DBPR) maintains license lookup tools for engineers and other regulated professions through its online licensing portal. Don't take a firm's word for it; verify. Ask for a sample report before signing. A good reserve study should list every reserve component individually with its remaining useful life and replacement cost, not lump items into vague categories. Ask how many similar buildings (same age, same coastal exposure, same construction type) the firm has studied in the past two years. Coastal buildings face faster deterioration from salt air and wind-driven rain, and a firm with no coastal experience may underestimate remaining useful life on roofing, railings, and exterior coatings. Get at least two bids for anything beyond a small HOA update. Prices for comparable SIRS work can vary by a factor of two or three between firms in the same county, and the cheapest bid is sometimes cheapest because the inspection scope is thinner, not because the firm is more efficient.

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

These three terms get mixed up constantly, and the confusion costs boards money and time. A reserve study is a financial and physical planning document covering all reserve components (structural and non-structural) and produces a funding schedule. A SIRS (Structural Integrity Reserve Study) is Florida's narrower, statutorily-defined version of that study, limited to structural and life-safety components, required only for condo/co-op buildings 3+ stories, and it must feed directly into the association's reserve funding under 718.112. A milestone inspection is a different animal entirely: a one-time (then recurring) structural inspection under Fla. Stat. 553.899, triggered by building age (generally 30 years, or 25 years within 3 miles of the coast) and building height (3+ habitable stories), producing a Phase 1 and possibly Phase 2 engineering report on structural safety, not a funding plan. A building can need all three at different times: milestone inspection to check structural safety, SIRS to plan structural reserve funding, and a broader HOA-style reserve study to plan for non-structural items like landscaping equipment, pool resurfacing, and paving. For structural findings that come out of either the SIRS or milestone process, boards then have to figure out funding, which is where hoa special assessment and condo special assessment insurance become relevant reading.

Are HOA special assessments tax deductible?

For most owners, no. Special assessments for capital improvements or repairs to common elements are generally not deductible on a personal tax return, because the IRS treats them similarly to home improvement costs rather than deductible expenses. The IRS's guidance on rental and personal residence expenses draws a line between routine maintenance (sometimes deductible if the property is a rental) and capital improvements (added to the property's cost basis instead). There are two narrow exceptions worth knowing. If the unit is a rental property, a special assessment tied to repairs (not improvements) may be deductible as a rental expense in the year paid, per general IRS rules on rental property expenses. And if the assessment funds a capital improvement, it doesn't disappear as a tax matter, it gets added to the owner's cost basis in the property, which reduces capital gains tax owed when the property eventually sells. This isn't tax advice, and the line between "repair" and "improvement" gets fought over in real IRS guidance and case law constantly. Owners facing a large special assessment should talk to a CPA about their specific situation before assuming either way.

What happens if reserves aren't fully funded?

If reserves fall short when a major repair comes due, the association has three practical options: levy a special assessment, take out a loan (if bylaws and lenders allow it), or defer the repair, which usually makes it more expensive later and can create safety or insurance problems. Florida's post-Surfside legislative changes made underfunding riskier for condo boards specifically. Once a SIRS is completed, Fla. Stat. 718.112(2)(f) requires the association to maintain reserves for the SIRS-covered structural components at full funding levels, and boards can no longer vote to waive or reduce that specific funding the way they historically could for general reserves. This was a direct legislative response to the 2021 Champlain Towers South collapse in Surfside, which killed 98 people and prompted the Florida Legislature to pass SB 4-D in 2022, later refined by SB 154 in 2023. HOAs under chapter 720 still have more flexibility: members can vote each year to waive or reduce reserve funding for HOA common elements, subject to the disclosure and threshold rules in Fla. Stat. 720.303. That flexibility is exactly why so many Florida HOAs end up with underfunded reserves and then a painful special assessment when the roof or pool finally needs replacement.

How often should a reserve study be updated?

Reserve industry practice, not Florida statute, generally recommends a full reserve study every 3 to 5 years, with an annual or biennial update reviewing costs and remaining useful life estimates in between. This update cycle is standard practice for associations trying to keep pace with construction cost inflation and changing component conditions. For Florida condo SIRS specifically, the statute requires the study to be updated at least every 10 years, per Fla. Stat. 718.112(2)(g), through a recertification process that runs alongside the milestone inspection timeline for the building. That's a legal minimum, not a best practice; a building with aging infrastructure or after a major storm event may need a fresh look sooner. Boards should also commission an update any time there's a major unplanned event: a storm that damages the roof, an insurance claim that changes replacement costs, or a capital project completed ahead of schedule. Waiting the full statutory interval after an event like that just means budgeting off stale numbers.

What does the board actually do with a reserve study once it's done?

A completed reserve study or SIRS report isn't the finish line, it's the starting point for the board's real work: building the report's numbers into the annual budget, scheduling the funding vote (for HOAs that can waive reserves), and communicating the plan to owners before assessments show up in their mailbox. This is where boards often stumble, not on the engineering, but on the administrative follow-through: tracking which components need funding by which year, keeping the study current as deadlines approach, and documenting the board's decisions in case of a dispute or an insurance question later. A $199 Building-Specific Board Compliance Kit (available at /board-kit-builder) is built for exactly that gap: it organizes the reserve study findings, SIRS and milestone deadlines, and owner communications into one schedule so the board isn't relying on a spreadsheet someone built in 2019 and forgot to update. It doesn't replace the engineer's inspection or offer a legal opinion on your documents, but it keeps the compliance calendar from falling through the cracks between studies. Whichever way a board organizes this, the discipline matters more than the tool. Boards that treat the reserve study as a one-time report to file away are the same boards that get blindsided by a special assessment five years later.

What should be in a reserve study report?

A usable reserve study report lists every reserve component individually, its installation date or age, useful life, remaining useful life, current replacement cost, and the funding method used (full funding, baseline, or a percent-funded target). It should also state clearly whether it meets SIRS requirements if the building needs one, since not every generic reserve study covers the specific structural items Florida law requires. Good reports include photos of each component's current condition, an executive summary a non-engineer board member can actually read, and a 20 to 30 year funding projection showing contribution levels needed to avoid a special assessment. If a report is just a spreadsheet of dollar totals with no component-level detail or photos, it's not going to hold up if an owner challenges the board's reserve decisions later. For SIRS reports specifically, Fla. Stat. 718.112(2)(g) requires the study to identify each structural component, estimate remaining useful life and replacement cost, and recommend reserve fund contributions, delivered by the qualified professional performing the inspection.

Frequently asked questions

What is a reserve study?

A reserve study is a physical inspection and financial forecast of an association's common-area components (roof, pool, paving, elevators, structural elements) that estimates remaining useful life and replacement cost, then sets a funding schedule so the association isn't hit with surprise special assessments when something big needs replacing.

What is a reserve study for an HOA?

For an HOA, a reserve study covers common amenities and infrastructure the association owns, like clubhouses, pools, gates, private roads, and retention ponds. It's less regulated than Florida's condo SIRS requirement, but chapter 720 still ties reserve funding decisions to a documented study or budget disclosure.

What is an HOA assessment?

An HOA assessment is a fee the association charges owners under authority in its governing documents and state statute. Regular assessments fund ongoing operations and reserves; special assessments are one-time charges to cover shortfalls, emergencies, or capital projects reserves don't fully cover.

How much should an HOA have in reserves?

There's no single legal number; it depends on the property's components and age. Reserve industry heuristics suggest funding at or above roughly 70% of a full study's theoretical requirement to avoid special assessment risk, though Florida SIRS-covered condo components now have stricter no-waiver funding rules under Fla. Stat. 718.112(2)(f).

How much does a reserve study cost?

Non-SIRS HOA reserve study updates typically run $1,500 to $6,000; full studies on large condos run $5,000 to $20,000+. Florida SIRS studies, which must be done by a licensed engineer or architect, commonly cost $3,000 to $15,000+ depending on building size and complexity.

Are HOA special assessments tax deductible?

Generally no for a primary residence; special assessments for capital improvements typically get added to the property's cost basis rather than deducted. Rental property owners may be able to deduct assessments tied to repairs (not improvements) as a rental expense. Confirm specifics with a CPA.

What's the difference between a reserve study and a SIRS?

A reserve study is a general financial planning document covering all common-area components. A SIRS (Structural Integrity Reserve Study) is Florida's narrower, statutory version limited to structural and life-safety components, required for condo/co-op buildings 3+ stories, and must be performed by a licensed engineer or architect under Fla. Stat. 718.112.

Who can legally perform a Florida SIRS?

Fla. Stat. 718.112 requires the SIRS be performed by a person qualified to perform such studies, meaning a licensed engineer or licensed architect. General reserve specialists without that license cannot legally perform the structural inspection portion, even if they handle the financial modeling.

How often does a reserve study need updating?

Industry practice recommends a full study every 3 to 5 years with interim updates in between. Florida's SIRS specifically must be updated at least every 10 years under Fla. Stat. 718.112(2)(g), though storm damage or major capital work can justify an earlier update.

Do all HOAs need a reserve study by law in Florida?

Not exactly. Florida's SIRS mandate applies to condo and co-op associations 3+ stories, not typical single-family HOAs. HOAs fall under Fla. Stat. 720.303, which requires reserve funding for items over $10,000 unless members vote to waive or reduce it; a reserve study isn't always legally mandatory but is the only reliable way to comply responsibly.

What happens if my association doesn't get a required SIRS done?

Associations that skip a legally required SIRS lose the ability to waive or reduce reserve funding and can face liability if a structural problem later causes damage or injury. Boards should confirm specific deadlines and consequences with their association's counsel, since enforcement details can change with each legislative session.

Can a reserve study company also do the milestone inspection?

Sometimes, if the firm employs licensed engineers or architects qualified for both scopes, but they're legally separate deliverables under different statutes (Fla. Stat. 718.112 for SIRS, Fla. Stat. 553.899 for milestone inspections). Ask any firm bidding on both jobs to clearly separate pricing and deliverables for each.

How do I know if a reserve study company is legitimate?

Verify the individual engineer's or architect's license directly through Florida DBPR's online license lookup rather than trusting a company website. Ask for sample reports, check for Reserve Specialist or APRA PRA credentials for non-SIRS work, and get at least two bids for anything beyond a small update.
