TL;DR
A reserve study is a professional estimate of when major building components will need repair or replacement and how much to save now. Miami condo boards 3 stories and up must fund reserves for items covered by the Structural Integrity Reserve Study (SIRS) under Florida Statutes 718.112. Studies typically cost $3,000 to $20,000+ depending on building size and complexity.
What is a reserve study?
A reserve study is a report, usually prepared by an engineer or a reserve specialist, that inventories a building's major shared components (roof, elevators, pool, structure, plumbing, painting, pavement) and estimates two things: the remaining useful life of each item and what it will cost to repair or replace it. The output is a funding schedule that tells the board how much money to set aside each year so the association isn't blindsided by a $2 million roof replacement with $40,000 in the bank. Most studies have two components: a physical analysis (site visit, component inspection, life expectancy estimates) and a financial analysis (current reserve balance, contribution schedule, funding plan options like full funding or baseline funding). For Florida condos, a subset of this work is now mandated by law and called a Structural Integrity Reserve Study, or SIRS, which specifically covers roof, load-bearing walls, primary structural members, floor, foundation, fireproofing, electrical systems, plumbing, and waterproofing, among other items listed in Florida Statutes 718.112(2)(g) [1]. A general reserve study (sometimes done voluntarily, or required by an association's own bylaws) can be broader, covering things like pools, parking lot resurfacing, and painting. A SIRS is narrower. It's mandatory. Boards in buildings 3 stories or higher need to understand they may need both: the statutory SIRS for structural items, and a full reserve study if they want funding certainty on everything else.
What is a reserve study for an HOA?
For a homeowners association (as opposed to a condo), a reserve study serves the same core purpose: figure out what the community owns in common (roads, clubhouse, pool, fencing, drainage) and build a savings plan so those items get repaired on schedule without a surprise bill to owners. The legal requirement is different from condos, though. Florida's SIRS and mandatory structural reserve rules under 718.112 apply to condominiums, not to single-family HOAs. Homeowners associations governed by Chapter 720 generally aren't subject to the same structural reserve mandate, though HOA boards should still check their own declaration and bylaws, since many require a reserve study or reserve funding schedule as a matter of contract, not statute. If your community has a multi-story clubhouse or shared parking garage, ask your association's counsel whether any structural provisions apply. See our overview of hoa reserve study requirements for a state-by-state comparison of what's mandatory versus optional.
How much does a reserve study cost in Miami?
| Basic reserve study (non-structural) | $3,000-$8,000 | Reserve specialist or engineering firm | |
|---|---|---|---|
| SIRS (structural reserve study) | $5,000-$20,000+ | Licensed engineer or architect | |
| Milestone inspection, phase 1 | $3,000-$15,000 | Licensed engineer or architect | |
| Milestone inspection, phase 2 (if triggered) | $15,000-$75,000+ | Licensed engineer or architect | These ranges are general market estimates, not fixed prices. Get at least three quotes. Ask each firm to itemize what's included: site visits, drone or thermal imaging, garage post-tensioning cable testing, and report format. |
Reserve study fees vary by building size, number of components inspected, and whether the report needs a licensed engineer's stamp for structural items. As a rough range seen across Florida condo markets, expect $3,000 to $8,000 for a smaller building (under 50 units, straightforward structure) and $10,000 to $20,000 or more for larger, older, or coastal high-rises where engineers need to access seawalls, garages, balconies, and complex mechanical systems. The SIRS piece specifically requires a visual inspection performed by a licensed engineer or architect under Florida Statutes 718.112(2)(g)2 [1]. That professional requirement is part of why costs run higher than a basic reserve study checklist. Milestone inspections (a separate but related requirement for buildings 3 stories or more, generally at 30 years, or 25 years if within 3 miles of the coast) are billed separately. A small building's phase one report might run a few thousand dollars. A large coastal tower needing a full phase two structural investigation can run well over $30,000 to $50,000, per guidance from the DBPR [2]. Miami-Dade and Broward counties have run their own 40-year/50-year recertification programs since the 1970s, predating the statewide milestone law passed after the Surfside collapse, so buildings there may already have engineering reports on file that a reserve study firm can use as a starting point, which can lower costs somewhat. | Service | Typical cost range | Who performs it |
How do I choose a reserve study company in Miami?
Start by confirming licensure. For the SIRS structural components, Florida law requires the inspection be performed by a person qualified to perform such inspections, generally a licensed engineer or architect under Chapter 471 or 481 [1][2]. Verify any individual's license status directly through the DBPR license search rather than trusting a company's marketing page. Ask for local Miami-Dade and Broward experience specifically. Coastal high-rises face salt air corrosion, storm surge exposure, and older concrete mix designs (some 1970s-80s buildings used beach sand aggregate, contributing to rebar corrosion issues documented after Surfside). A firm that mostly works on inland Central Florida garden condos may not have the coastal-specific expertise your building needs. Get a sample report. A good reserve study should show, item by item, useful life remaining, replacement cost estimate, and funding recommendation, not a vague summary paragraph. Ask how they handle inflation assumptions and whether they offer a full-funding versus baseline-funding comparison, since your board will need to pick a funding method and disclose it to owners. Check references from other condo boards, ideally buildings of similar age, height, and coastal exposure. A study for a 4-story 1980s building 2 miles inland doesn't tell you much about a firm's fitness for a 20-story 1974 oceanfront tower.
What is an HOA assessment?
An assessment is the money an association charges owners to cover shared expenses, both routine and unexpected. There are two basic kinds: regular assessments (the recurring monthly or quarterly dues that fund operating costs and reserve contributions) and special assessments (a one-time or limited-duration charge to cover a specific, often unbudgeted cost, like a roof replacement or storm damage repair). Under Florida Statutes 718.116, condo associations can levy assessments as authorized by the declaration, and owners are jointly and severally liable for common expenses allocated to their unit [3]. The exact process, notice requirements, and vote thresholds for a special assessment depend on your declaration and bylaws; a board should confirm the specific process with association counsel before levying one. Assessments aren't optional dues you can skip if you disagree with a board decision. Florida law generally treats them as a lien-backed obligation, meaning unpaid assessments can result in a lien against the unit and, in some cases, foreclosure. See hoa special assessment for more on how special assessments get triggered and challenged.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure that fits every building, because the right reserve balance depends on your components, their age, and their replacement cost, which is exactly what a reserve study calculates. But Florida law has moved from advisory to mandatory on this question for condos. As of the reforms following the Surfside collapse, condo associations 3 stories or higher can no longer waive or reduce reserve funding for the SIRS-covered structural components (roof, load-bearing walls, floor, foundation, fireproofing, electrical, plumbing, waterproofing, and similar items) starting with the fiscal year that includes December 31, 2024 [1]. Before this law, many Florida boards had voted year after year to waive or underfund reserves, which is part of why some buildings went into 2024 needing five- and six-figure special assessments overnight. The practical target most reserve specialists recommend is full funding, meaning the reserve balance tracks close to 100% of the theoretical value based on each component's age and remaining life. Baseline funding (keeping the balance just above zero, replenished only as bills come due) is legal for non-SIRS items but leaves almost no cushion for early failures or cost overruns. Ask your reserve study firm to model both a full-funding and baseline scenario so your board can see the assessment tradeoff in dollars, more than percentages. For the state's stance on this issue after 2023 legislative changes, see florida condo reserve fund relief.
Are HOA or condo special assessments tax deductible?
Generally, no, not for an individual owner's federal income taxes, if the unit is your personal residence. The IRS treats special assessments for capital improvements to a condo or HOA-owned common area similarly to a capital expenditure. That means they typically aren't deductible as an expense in the year paid; instead, they may be added to your cost basis in the property, which can reduce capital gains tax when you sell [4]. There's a narrow exception: if you rent out the unit, special assessments related to repairs or maintenance on a rental property may be deductible as a rental expense, and assessments tied to capital improvements can typically be depreciated over time. This is genuinely fact-specific. A CPA or tax attorney familiar with rental property rules should review your situation; don't rely on a board newsletter or a Facebook group for tax advice here. Some owners assume post-Surfside emergency assessments for structural repairs get special tax treatment because they're mandated by new state law. As of current IRS guidance, there's no such carve-out; the capital-improvement-versus-basis-adjustment framework still applies [4].
What triggers a mandatory reserve study or SIRS in Florida?
Height and building age, not building type, are the triggers. Under Florida Statutes 718.301 and 718.112, condominium buildings 3 stories or more in height must have a SIRS completed, generally by December 31, 2024 for the initial deadline, with recurring studies required at least every 10 years after that [1][5]. Buildings must also comply with the milestone inspection schedule: initial inspection at 30 years from the certificate of occupancy, or 25 years if the building is within 3 miles of the coastline, and every 10 years thereafter [5]. Miami-Dade's coastal geography means most condo towers in the county fall under the 25-year rule rather than the 30-year rule. A board unsure which threshold applies should check the certificate of occupancy date and consult a licensed surveyor or engineer to confirm distance from the coastline, since the statute's mileage measurement isn't always intuitive for barrier island or bay-adjacent buildings. Cooperatives (co-ops) 3 stories or higher are subject to similar milestone inspection requirements under Chapter 719 of the Florida Statutes [6]. Co-op boards shouldn't assume they're exempt just because they're not technically condos.
What do these studies actually contain, and how do boards use the results?
A useful reserve study report gives your board three deliverables: a component inventory (what you own, in common, and its condition), a funding plan (how much to collect each year, and under which method), and a disclosure summary your treasurer can present to owners at the annual meeting. Boards often make the mistake of treating the report as a one-time compliance checkbox rather than a working document. The best practice is to update the financial projections annually (inflation, interest earned on reserve accounts, actual project costs coming in) even though the full physical reinspection is only required every 10 years under the SIRS statute [1]. Boards should also cross-reference the reserve study against the milestone inspection engineering report when both exist for the same building, since a milestone report may flag urgent structural issues that should reset the reserve study's assumed remaining useful life for that component. A reserve study for condo association walk-through covers how to read a sample report line by line if your board has never seen one before. Once your board has a signed reserve study and milestone report in hand, the harder job starts: turning those documents into a calendar of deadlines, budget lines, and owner notices. That's the gap a $199 one-time Board Compliance Kit is built to close, organizing your building's specific SIRS and milestone dates, reserve contribution schedule, and required owner disclosures into one place your board can actually use month to month. The kit doesn't replace your engineer or reserve specialist; it organizes what they hand you.
What if my building can't afford full reserve funding right away?
Some boards facing a first-year SIRS-compliant budget see contribution numbers that would require large assessment increases, sometimes doubling or tripling monthly dues. Florida has provided limited relief mechanisms since the original 2022 and 2023 reform laws, including phased compliance options and, in some legislative sessions, extended deadlines for specific circumstances, so boards should check current-year statute text rather than relying on older news coverage. A board that genuinely can't fund the full SIRS reserve immediately should talk to association counsel about lawful options: special assessment installment plans, association loans (many banks now offer condo-specific lines of credit for capital projects), or phased capital improvement schedules that spread the work (and cost) over several years where the engineering report allows it. What a board should not do is simply vote to waive the SIRS reserve requirement the way older Florida law allowed for general reserves. That waiver option no longer exists for the SIRS-covered structural components starting with fiscal years including December 31, 2024 [1]. Confirm current requirements with your association's counsel, since the legislature has amended this statute multiple times since Surfside and may do so again.
How does a Miami condo board actually pick a firm: engineer, reserve specialist, or both?
For the SIRS structural components, you need a licensed engineer or architect, full stop. That's a statutory requirement, not a preference [1]. For the broader financial reserve study covering non-structural items (paint, pavement, pool equipment, amenities), many boards hire a reserve specialist firm, which may or may not have an in-house licensed engineer. Some firms offer both services under one roof and can produce a combined SIRS-plus-full-reserve-study report, which simplifies scheduling and can reduce duplicate site visits, lowering total cost. Others specialize narrowly in the structural inspection and subcontract or refer out the financial reserve modeling. Neither approach is wrong, but ask upfront which model a firm uses so your board timeline reflects reality. Before signing a contract, confirm four things: the individual engineer's license number and status through DBPR's public license search, the firm's general liability and professional errors-and-omissions insurance, a written scope of work listing every SIRS-required component under 718.112(2)(g), and a delivery date in writing. Boards that skip the written scope often discover mid-project that pool equipment or seawalls weren't included and face a change order.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment of a building's major shared components (roof, elevators, structure, plumbing) that estimates remaining useful life and replacement cost, then builds a savings schedule. In Florida, condo buildings 3 stories or higher must complete a Structural Integrity Reserve Study (SIRS) covering specific structural items under Florida Statutes 718.112(2)(g).
What is a reserve study for an HOA?
For a homeowners association, a reserve study inventories common-area assets (roads, clubhouse, pool, fencing) and creates a funding plan so repairs don't require emergency special assessments. Unlike condos under Chapter 718, single-family HOAs under Chapter 720 generally aren't subject to Florida's mandatory SIRS law, though many declarations require a reserve study by contract.
What is an HOA assessment?
An assessment is a charge an association levies on owners to cover shared expenses. Regular assessments fund routine operating costs and reserves; special assessments cover a specific unbudgeted expense, like storm repair or a mandated structural fix. Florida Statutes 718.116 makes owners jointly liable for their share of common expense assessments.
How much should an HOA have in reserves?
There's no universal dollar figure; it depends on your components' age, condition, and replacement cost, which a reserve study calculates specifically for your building. Florida condos 3 stories or higher can no longer waive reserve funding for SIRS-covered structural items starting with fiscal years including December 31, 2024, under Florida Statutes 718.112.
How much does a reserve study cost?
Basic non-structural reserve studies typically run $3,000-$8,000. A SIRS, requiring a licensed engineer or architect, generally costs $5,000-$20,000 or more depending on building size and complexity. Large coastal high-rises with structural issues or extensive amenities can exceed that range; get multiple itemized quotes before hiring.
Are HOA special assessments tax deductible?
Generally not for a primary residence; the IRS typically treats them as a capital expense added to your cost basis rather than a deductible expense, which can lower future capital gains tax when you sell. Rental property owners may have different treatment for repair-related assessments. Consult a CPA familiar with rental and real estate tax rules for your specific situation.
What are HOA assessments used for?
Regular assessments cover routine operating costs (landscaping, insurance, staff, utilities) and reserve contributions for future major repairs. Special assessments cover a specific, often urgent expense not covered by the regular budget, such as a roof replacement, storm damage, or a newly mandated structural repair identified in a milestone inspection or SIRS report.
Do all Florida condos need a SIRS?
Condominium buildings 3 stories or higher in height need a completed SIRS, per Florida Statutes 718.112. Buildings under 3 stories are generally exempt from the SIRS mandate, though associations may still choose to complete a voluntary reserve study for financial planning purposes.
How often does a Florida condo need a new reserve study or SIRS?
The SIRS must be updated at least every 10 years under Florida Statutes 718.112(2)(g). Milestone structural inspections follow a separate schedule: an initial inspection at 30 years from the certificate of occupancy (25 years if within 3 miles of the coast), then every 10 years after that.
Who is qualified to perform a SIRS in Florida?
The visual structural inspection portion of a SIRS must be performed by a person qualified to conduct such inspections, generally a Florida-licensed engineer or architect, per Florida Statutes 718.112(2)(g)2. Boards should verify an individual's license status directly through the DBPR's public license search before hiring.
Can a Florida condo board waive reserve funding?
Not anymore for SIRS-covered structural components. Since the fiscal year that includes December 31, 2024, associations 3 stories or higher can no longer vote to waive or reduce reserves for items covered under Florida Statutes 718.112(2)(g). Non-SIRS reserve items may still be subject to waiver depending on current statute and association bylaws; confirm with counsel.
Why do Miami condos face higher reserve study and milestone costs than inland buildings?
Coastal high-rises face salt air corrosion, storm surge exposure, and, in some older buildings, concrete mix issues linked to beach sand aggregate. Engineers often need more extensive testing (post-tensioning cable checks, seawall assessment, garage corrosion analysis) than an inland garden-style condo, which raises both SIRS and milestone inspection costs.
