What is a condo reserve study, and what should it cost

Last updated 2026-07-24

what is a reserve study, in plain terms

A reserve study is a financial and physical planning document. Someone (usually a licensed engineer, sometimes a reserve specialist with a credential like RS or PRA) walks the property, looks at the roof, the pavement, the pool deck, the elevators, the plumbing risers, and every other major shared component. They estimate how many years each item has left and what it will cost to fix or replace it. Then they build a savings schedule so the association isn't caught flat-footed when the roof fails in year 18 instead of year 20. Think of it like a long-range maintenance budget with real numbers attached, not a guess pulled from last year's line item. A good study has two parts: a physical analysis (what's out there, how old is it, how long will it last) and a financial analysis (how much is in reserves now, how much is coming in, and what the funding gap looks like over 20 or 30 years). For Florida condos over three stories, this isn't optional anymore. The Structural Integrity Reserve Study (SIRS) required under Fla. Stat. 718.112(2)(g) is a specific, narrower version of a reserve study that covers a defined list of structural components: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing and fire protection systems, plumbing, electrical, waterproofing, and windows and exterior doors ^[1]. A general reserve study can cover more than that (landscaping, paving, pools), but SIRS is laser-focused on the stuff that keeps the building standing. For a deeper walk-through of what goes into the document itself, see our reserve study guide.

what is a reserve study for hoa (as opposed to a condo)

HOAs (homeowners associations governing single-family homes or townhomes, not condominiums) generally aren't under the same statutory reserve study mandate as condos in Florida. Fla. Stat. Chapter 720 governs homeowners associations, and while it addresses reserves and budgeting, it doesn't impose the SIRS structural inspection requirement that Chapter 718 puts on condominiums three stories and taller ^[2]. That said, plenty of HOAs voluntarily commission reserve studies anyway, because it's good practice regardless of what the statute says. An HOA reserve study looks at the same kinds of shared assets, roads if the HOA owns them, clubhouse roofs, pool equipment, retaining walls, irrigation systems, and builds a savings plan the same way a condo study does. The difference is enforcement: no state agency is checking an HOA's homework the way DBPR oversees condo compliance. If your HOA has condo-like buildings (multi-story attached units it owns and insures as a single structure), it's worth checking with counsel whether Chapter 718 definitions apply to any part of the property. See our hoa reserve study breakdown for more on how HOA obligations differ from condo obligations.

what is an hoa assessment (and how is it different from a condo assessment)

An assessment is money the association charges each owner, on top of or instead of regular dues, to cover a specific cost. Regular assessments fund the annual operating budget: landscaping, insurance, management fees, utilities for common areas. Special assessments cover something the regular budget can't, usually a big unplanned repair or a reserve shortfall. "HOA assessment" and "condo assessment" work the same basic way, they're both mandatory charges levied under the association's governing documents and state statute, but the legal mechanics differ slightly. Condo assessments in Florida are governed by Chapter 718 and typically tied to each unit's percentage ownership in common elements as set out in the declaration. HOA assessments fall under Chapter 720 and are usually allocated per lot, sometimes evenly, sometimes by square footage or other formula in the declaration. A special assessment is what happens when the math from a reserve study (or a Milestone Inspection finding) shows a gap between what's saved and what's needed. If your reserve study says the roof needs $800,000 in three years and reserves only have $200,000, the board has two choices: raise regular assessments gradually, or hit owners with a special assessment. Nobody enjoys either option, but the special assessment is usually the more painful, more sudden version. For a full explanation of how these get triggered and calculated, read hoa special assessment.

what are hoa assessments used for, exactly

Assessments fund three broad buckets: day-to-day operations, reserve contributions, and emergency or one-time repairs. Operating assessments pay the electric bill for the lobby lights and the landscaper's monthly invoice. Reserve assessments (the regular contribution the board budgets each year) fund the long-term replacement schedule the reserve study lays out. Special assessments plug a hole when reserves and operating funds together can't cover a real cost. In Florida condos, boards are required to fund SIRS-covered components at a level that doesn't allow deferral or waiving of full funding for those specific line items, per the 2022 and 2023 amendments to 718.112 following the Surfside collapse ^[1]. That's a meaningful shift: before those changes, many associations could vote to underfund or skip reserve contributions entirely. For SIRS components (structural items) that's no longer legally an option for buildings that reached their reserve study milestone deadline. See florida condo reserve fund relief for the latest on any legislative adjustments to funding timelines, since lawmakers have revisited these deadlines more than once since 2022.

how much should an hoa or condo have in reserves

There's no single dollar figure or magic percentage that fits every building, and anyone who tells you "you need X% of budget in reserves" without knowing your building's age, components, and climate exposure is guessing. What matters is whether reserves match the actual, itemized replacement cost and timeline in a current reserve study. A rough industry rule of thumb some reserve specialists use: aim for a reserve fund that's at least 70% funded relative to the ideal (fully funded) balance calculated in your study, meaning the ratio of actual reserves to the theoretical full-funding target. That threshold isn't a Florida statutory requirement, it comes from broader community-association industry practice, and boards should treat it as a benchmark, not a legal floor. What Florida law does require, specifically: condo associations 3+ stories must have a SIRS completed by December 31, 2024 (for most buildings) and then must fund reserves for each SIRS component based on the study's findings, without the ability to waive or reduce that funding through a membership vote, per Fla. Stat. 718.112(2)(f)4 ^[1]. That's the real floor. Anything less specific is a benchmark, not a legal requirement. The honest answer to "how much should we have" is: get the study, look at the 20 or 30-year projection line, and see where your current balance sits against it. If you're 40% funded and the roof needs replacing in four years, that's your answer, regardless of what a generic percentage rule says.

how much does a reserve study cost in florida

Costs vary a lot depending on building size, number of components, and whether you're getting a full SIRS or a broader reserve study. For a mid-size condo (50 to 150 units), expect somewhere in the range of $3,000 to $15,000 for the study itself, though larger or more complex buildings with unusual structural conditions can run higher, sometimes $20,000 or more. A few things drive the price up or down: - Building height and unit count (more units, more components, more time on site)

• Whether it's a first-time study or an update (updates are usually cheaper because baseline data exists)
• Whether the engineer needs to access difficult areas (crawl spaces, seawalls, below-grade parking)
• Geographic location (South Florida coastal firms often charge more due to demand and licensing overhead) DBPR doesn't publish a fixed fee schedule for SIRS providers, since pricing is a private market between the association and the licensed professional, so boards should get at least two or three quotes from Florida-licensed engineers before signing a contract. The study itself is a one-time or periodic cost (many boards update every 3 to 5 years), it isn't a monthly or annual dues item, though the reserve savings the study recommends absolutely does become a recurring line in the budget. For line-item cost breakdowns by building type, see reserve study for condo association.

who actually performs a reserve study or SIRS

For SIRS specifically, Florida law requires the study be performed by a licensed engineer or architect. Fla. Stat. 718.112(2)(g) states the SIRS must be "performed by a person qualified to perform such visual inspection" and specifically references engineers and architects licensed under Florida law ^[1]. This is not a job for a property manager's spreadsheet or a board member's contractor cousin, however capable that contractor might be. General (non-SIRS) reserve studies are sometimes performed by reserve specialists who hold credentials like the Reserve Specialist (RS) designation, which isn't the same as an engineering license but does involve specific training in component life-cycle costing. For the structural components covered by SIRS, though, Florida requires the licensed engineer or architect route, full stop. Boards should confirm any provider's license status directly with DBPR before signing a contract. DBPR's licensee verification search lets you check whether an engineer or architect's license is active.

are hoa special assessments tax deductible

Generally, no, not for the individual homeowner claiming a personal income tax deduction, and this is one of the most common misunderstandings boards run into when owners push back on a big assessment bill. Regular HOA dues and special assessments for repairs or improvements to a personal residence are typically considered a personal, nondeductible living expense under IRS rules, similar to how home maintenance costs aren't deductible. There are narrow exceptions. If the unit is a rental property, a special assessment tied to repairs may be deductible as a rental business expense, and one tied to a capital improvement may need to be depreciated rather than deducted in full the year it's paid, under the general rules for rental property expenses described in IRS Publication 527 ^[3]. If part of the home is used for a qualifying home office, a portion of the assessment might be deductible under the home office rules in IRS Publication 587 ^[4]. None of this is board business to advise on, though. The honest answer for a board to give an angry owner is: "talk to your accountant, this isn't something we can tell you definitively, and it depends on how you use the unit."

how does a reserve study connect to the milestone inspection and SIRS deadline

They're related but not identical, and mixing them up causes real confusion for boards. The Milestone Inspection (required under Fla. Stat. 553.899) is a structural safety inspection, done at 30 years from the certificate of occupancy (25 years if within three miles of the coast), and every 10 years after that ^[5]. It answers the question: is the building structurally sound right now? SIRS, by contrast, is a financial planning document that projects future costs for specific structural components. It answers: how much money do we need to save, and by when, to replace or repair these components before they fail? Fla. Stat. 718.112(2)(g) sets the SIRS deadline at December 31, 2024, for most condominiums 3+ stories, with the study to be updated at least every 10 years ^[1]. A Milestone Inspection can trigger findings that feed directly into a SIRS or force an accelerated one. If the Milestone engineer flags a substantial structural concern, that report goes to the local building official and often reshapes the reserve study's assumptions about remaining useful life for that component. Boards juggling both deadlines on the same building often find it easier to schedule them close together, since the same engineering firm may be qualified to perform both, though state law doesn't require that. For the mechanics of the inspection deadline itself, see our milestone inspections hub. For organizing paperwork and deadlines across both requirements, boards sometimes use a structured system like the $199 Building-Specific Board Compliance Kit at /board-kit-builder, which organizes the documents, schedules, and notices a board needs to track, though the actual inspections and studies still have to be done by the licensed professionals the statute requires.

what happens if a board skips the reserve study or SIRS deadline

Consequences range from paperwork headaches to real legal exposure. Under Fla. Stat. 718.112, associations that fail to complete a required SIRS can face enforcement action, and individual board members who knowingly and willfully fail to fulfill these obligations can face personal liability in some circumstances, since board members owe a fiduciary duty to the association ^[1]. Practically speaking, missing the deadline also creates a paper trail problem at resale. Florida requires certain SIRS-related disclosures to buyers, and title companies and buyer's attorneys increasingly ask for proof of a completed SIRS before closing. A building without one can see deals slow down or fall through, and lenders in some cases are becoming more cautious about financing units in buildings with open Milestone or SIRS deficiencies, following heightened scrutiny after Surfside. There's also the practical risk: if the study never happens, the board never gets a clear number for what to save, which means special assessments arrive as surprises instead of planned costs. That's the scenario every board wants to avoid, not because of statute compliance for its own sake, but because surprise six-figure bills wreck owner trust and, in some cases, force owners to sell at a loss.

how often does a reserve study need to be updated

Florida law requires the SIRS to be updated at least every 10 years under Fla. Stat. 718.112(2)(g) ^[1]. Many reserve specialists recommend updating general (non-SIRS) reserve studies every 3 to 5 years, since material costs, inflation, and component conditions shift faster than a decade-long gap can capture accurately. A study done in year one of a 10-year window gets stale fast. Roofing material costs, insurance-driven code changes, and labor costs in Florida's construction market have moved quickly since 2020, and a study that assumed 2021 replacement costs will badly undershoot 2026 reality. Boards that only update on the statutory minimum schedule often find themselves needing a special assessment simply because the study itself was outdated, not because anything unexpected happened to the building. A practical middle ground many management companies suggest: full update every 5 years, with a lighter "reserve study update" (adjusting cost estimates for inflation without redoing the full physical inspection) every 2 to 3 years in between. This isn't a statutory requirement, it's just good practice for keeping the funding plan realistic.

Frequently asked questions

What is a reserve study?

A reserve study is a report, typically prepared by an engineer or reserve specialist, that inventories a building's major shared components, estimates each one's remaining useful life and replacement cost, and recommends a savings schedule so the association has money ready before something fails. Florida requires a specific structural version, SIRS, for condos 3+ stories under Fla. Stat. 718.112(2)(g).

What is a reserve study for an HOA?

For an HOA (homeowners association, not a condo), a reserve study covers shared assets like roads, clubhouses, pools, and retaining walls, and projects when they'll need replacement and how much that will cost. Unlike condos, Florida HOAs under Chapter 720 aren't subject to the same SIRS mandate, so these studies are typically voluntary rather than legally required.

What is an HOA assessment?

An HOA assessment is a mandatory charge to owners under the association's governing documents, used to fund operations, reserves, or one-time repair costs. Regular assessments cover the annual budget; special assessments cover unplanned or under-reserved costs, often triggered by a reserve study finding a funding gap.

How much should an HOA have in reserves?

There's no single statutory percentage that fits every property. Industry benchmarks (not Florida law) suggest aiming for at least 70% funded relative to a reserve study's calculated full-funding target, but the real answer comes from your specific study: compare your current balance to the itemized 20-to-30-year projection and see where the gaps are.

How much does a reserve study cost?

Typical costs run $3,000 to $15,000 for mid-size condos, with larger or structurally complex buildings sometimes exceeding $20,000. Pricing depends on unit count, building height, whether it's a first-time study or an update, and site access difficulty. Get quotes from at least two or three Florida-licensed engineers before signing.

Are HOA special assessments tax deductible?

Generally no, for a personal residence they're treated as a nondeductible personal expense, similar to regular home maintenance. Exceptions can apply for rental units or qualifying home-office use, but that depends on individual tax circumstances. Owners should ask their own accountant rather than rely on board guidance for tax treatment.

What's the difference between a reserve study and a Milestone Inspection?

A Milestone Inspection (Fla. Stat. 553.899) checks current structural safety at 25 or 30 years depending on coastal proximity. A reserve study, including SIRS, is a financial planning document projecting future repair costs and savings needs. They're related but answer different questions: one is about safety now, the other about money later.

Who is legally allowed to perform a SIRS in Florida?

Fla. Stat. 718.112(2)(g) requires SIRS be performed by a person qualified under Florida law, specifically a licensed engineer or architect. Boards should verify license status directly through DBPR's licensee search before signing any contract.

Does every Florida condo need a SIRS?

Condominiums with buildings three stories or taller are generally required to complete a SIRS, with most needing completion by December 31, 2024, and updates at least every 10 years after. Buildings under three stories, and certain smaller or exempt associations, may fall outside this requirement, so confirm specifics with your association's counsel.

What happens if reserves run short after a reserve study?

If reserves fall short of what the study shows is needed, the board typically has to raise regular reserve contributions, levy a special assessment, or both. For SIRS-covered structural components, Florida law generally doesn't allow the board to waive or reduce that funding through a membership vote once the study is complete.

How is a reserve study different from a regular home inspection?

A home inspection is a one-time snapshot of a single unit's condition, usually for a buyer. A reserve study is an association-wide, ongoing financial planning tool covering shared building components (roof, structure, plumbing, elevators) and projecting decades of future costs, not a one-time pass/fail check.

Can a small condo association skip the reserve study to save money?

For buildings 3+ stories in Florida, skipping the SIRS isn't a legal option once the statutory deadline applies; enforcement and personal board liability risks exist for willful noncompliance under Fla. Stat. 718.112. Skipping it to save money upfront often costs far more later through emergency assessments and resale complications.
