TL;DR
A reserve study in Miami is a professional analysis of your building's major components (roof, structure, plumbing, painting) and the money needed to replace them. Florida law now requires condo associations to fund reserves for items covered by a structural integrity reserve study (SIRS), with no more waiving full funding for those line items starting in 2025.
What is a reserve study?
A reserve study is a professional evaluation of a building's major shared components, how much life each one has left, and how much money the association needs to set aside to replace them without a surprise bill. Think roof, elevators, painting, pavement, plumbing risers, structure, and (for coastal buildings) balcony waterproofing and seawalls. A good 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 projection showing what the association should be contributing each year to reserves so the money is there when the roof needs replacing in year 18 or the elevator needs modernizing in year 22. In Florida, reserve studies come in two flavors that boards often confuse. A traditional reserve study (sometimes just called a reserve analysis) covers everything the association wants funded, cosmetic items included. A structural integrity reserve study, or SIRS, is narrower and statutory: it covers only the load-bearing and life-safety components listed in Florida Statute 718.112(2)(g), and it is now mandatory for most condos three stories and taller [1]. For the statute itself and how SIRS differs from a general reserve study, see our reserve study breakdown. Miami adds its own wrinkle. Because so much of the county's condo stock sits within a few miles of saltwater, corrosion and waterproofing failures show up faster here than in inland Florida. A reserve study for a 1970s building on Collins Avenue is going to flag different priorities, and often shorter timelines, than the same building type in Ocala.
What is a reserve study for an HOA (and how is it different from a condo's)?
For a homeowners association, a reserve study covers the components the HOA itself owns and maintains, not individual homes. That usually means roads, clubhouse, pool, gates, drainage, and sometimes roofs if the HOA insures them. The purpose is identical to a condo's: figure out what breaks and when, and save for it instead of special-assessing owners at the worst possible moment. The legal requirements diverge sharply, though. Florida's SIRS mandate under Section 718.112 applies to condominiums, not to most single-family HOAs [1]. Homeowners associations are governed more by Chapter 720, and while many HOAs voluntarily commission reserve studies (smart move, especially for gated communities with private roads or lift stations), there's no statewide law forcing a Florida HOA to get one or to fully fund reserves the way condos now must. Some HOA declarations require it internally; check yours. For HOA-specific mechanics, our HOA reserve study guide walks through what boards typically include. Bottom line: if you're on a condo board in a building three stories or taller, a SIRS is likely mandatory. If you're on an HOA board, it's a strong best practice with no statewide mandate attached, though your county or declaration might say otherwise. Confirm with your association's counsel.
How much does a reserve study cost in Miami?
| Basic HOA reserve study (no engineer required) | $2,500 - $6,000 | Roads, amenities, non-structural common elements | |
|---|---|---|---|
| Full condo reserve study | $3,000 - $10,000 | All common elements, cosmetic and structural | |
| SIRS (licensed engineer/architect required) | $8,000 - $25,000+ | Only the statutory structural/life-safety components [1] | |
| Milestone inspection (separate but related) | $10,000 - $75,000+ depending on size | Structural safety of the building at 25/30 years [2] | These are planning ranges, not quotes. Get at least two proposals before your board signs anything, and confirm the provider is licensed to perform the specific service. DBPR maintains license lookups for the professionals involved. |
Cost depends heavily on building size, number of components, and whether you're getting a full reserve study or the narrower statutory SIRS. As a rough range seen across Florida licensed engineering and reserve firms, a basic reserve study for a small condo (under 50 units) tends to run $3,000 to $7,000. Larger or more complex buildings, especially coastal high-rises needing a licensed engineer's structural assessment for SIRS components, commonly run $8,000 to $20,000 or more. Miami-Dade pricing tends toward the higher end of any statewide range. Licensed structural engineers and reserve specialists here are in heavy demand, driven by the same milestone inspection and SIRS deadlines hitting thousands of buildings at once. If your building already needs a 25 or 30 year milestone structural inspection under Section 553.899, some engineering firms will bundle that inspection with SIRS data collection, which can save money versus hiring separately. Ask about bundling before you sign two separate contracts. A quick range comparison: | Study type | Typical Florida cost range | What it covers |
How much should an HOA (or condo) have in reserves?
There's no single statewide dollar figure, because the right reserve balance depends entirely on your building's age, component inventory, and remaining useful life of each item. What the law does specify, for condos, is the funding method: since the SIRS mandate took effect, associations can no longer vote to waive or reduce reserve funding for components covered by a structural integrity reserve study. Florida Statute 718.112(2)(f) states that reserve funds for items required to be included in a SIRS "may not be waived or reduced" [1]. A reserve study answers the "how much" question building by building. It typically expresses the target as a percent funded, meaning your current reserve balance divided by the ideal balance if every component were funded exactly to its age-adjusted share of replacement cost. Reserve specialists and community association trade groups commonly treat 70% funded or higher as healthy, and anything under 30% funded as a red flag likely headed for a special assessment, though no single number is legally required in Florida. For HOAs without a mandatory funding law, boards should still aim for a documented reserve study result rather than guessing. An association sitting at 15% funded with a roof due in three years isn't a hypothetical problem. It's a special assessment with a due date already written on the calendar, whether the board has acknowledged it or not.
What is an HOA assessment (and how does it differ from a condo assessment)?
An HOA assessment is a fee the association charges owners, usually monthly or annually, to cover shared expenses: landscaping, insurance, management, utilities for common areas, and contributions to reserves. It's the HOA equivalent of a condo's monthly maintenance fee, and it's mandatory under the association's governing documents, not optional dues. Condo associations use the same basic mechanism but call it a maintenance fee or condo assessment, and Florida Statute Chapter 718 governs how those are calculated, billed, and enforced for condominiums specifically [1]. Both HOAs (Chapter 720) and condos (Chapter 718) can also levy a special assessment: a one-time, often large charge outside the regular budget, triggered by an unexpected repair, a reserve shortfall, or a state-mandated project like SIRS-driven work that reserves didn't cover [3]. The practical difference boards feel: condo special assessments tied to structural or SIRS-related repairs get extra scrutiny because the underlying law (718.112) is specific about what must be inspected and funded. HOA special assessments are usually more flexible, governed mainly by the declaration and board resolution process. Either way, owners generally get formal notice and, depending on the documents, sometimes a vote. See our breakdown of the HOA special assessment process for the notice and voting mechanics that typically apply.
Are HOA and condo special assessments tax deductible?
For most owners, no. Special assessments paid to a homeowners association or condo association are generally treated as a capital expense or personal living expense by the IRS, not a deductible cost, in the same way regular HOA dues aren't deductible for a primary residence [4]. The IRS doesn't have a Florida-specific carve-out; this is federal tax law that applies regardless of state. There are narrow exceptions. If you rent out the unit, the portion of assessments related to the rental use may be deductible as a rental expense, and assessments tied to specific capital improvements can sometimes be added to your cost basis, which reduces capital gains tax when you eventually sell. If you use part of the home for a qualifying home office, a proportional share might be deductible there too. This is genuinely a case-by-case tax question, and the honest answer for most owner-occupants is simple: keep your assessment notices and paid receipts, but don't expect a deduction on your personal return. Talk to a CPA before assuming otherwise, especially with a large SIRS-related special assessment that might affect cost basis. IRS Publication 530 covers homeowner expenses and is the right starting reference [4].
What does a SIRS require in Miami-Dade specifically?
Miami-Dade condos three stories or higher, and condos anywhere in Florida meeting that height threshold, must complete a structural integrity reserve study once the building reaches 30 years old (or 25 years old if within three miles of the coastline), and every 10 years after that [1] [2]. Given how much of Miami-Dade sits within three miles of Biscayne Bay or the Atlantic, a large share of the county's condo stock falls under the 25-year trigger, not the 30-year one. The SIRS must be performed by a licensed engineer or architect, and it has to cover, at minimum, the load-bearing walls, primary structural members, roof, fireproofing, electrical systems serving common elements, plumbing serving common elements, and waterproofing/exterior finishes, plus any other item with a deferred maintenance expense over $10,000 that would threaten habitability if left unaddressed [1]. The statute is explicit that the study "must include a study of the reserve funds required for future major repairs and replacement of the common areas" for those items. Miami-Dade also runs its own longstanding building recertification program under county code, requiring structural and electrical recertification at 40 years and every 10 years after, separate from and older than the statewide milestone inspection law. Boards sometimes conflate the two. They're related but not identical requirements; your building may owe both a county recertification and a state milestone/SIRS package on overlapping but not always matching schedules. Confirm your specific deadlines with your association's engineer and the Miami-Dade building department.
When is a reserve study or SIRS due for my building?
Timing depends on your building's age and distance from the coast, and this is where boards most often get caught off guard. The statutory trigger points are: - Buildings reaching 30 years old: SIRS due, then every 10 years after.
- Buildings within three miles of a coastline reaching 25 years old: SIRS due, then every 10 years after.
- Milestone structural inspection (separate law, Section 553.899): due at 30 years for most buildings, or 25 years for coastal buildings, then every 10 years, with local building officials able to require it earlier for buildings showing distress [2]. Most of Miami-Dade's barrier island and bayfront condo stock, from Miami Beach to Key Biscayne, falls under the 25-year coastal trigger, which caught a lot of older buildings off guard when the law tightened after the 2021 Surfside collapse. If your building was built in the late 1980s or 1990s and sits near the water, don't assume you have until the 30-year mark. Get your engineer to confirm the applicable trigger date in writing early, because scheduling a licensed structural engineer in South Florida during peak SIRS/milestone season can take months, not weeks.
How do we actually run this process without losing our minds?
Start with the engineer, not the spreadsheet. Hire a licensed professional for the SIRS and, if separately required, the milestone inspection, before worrying about funding math. DBPR's licensing search lets you verify an engineer or architect's license status before signing anything. Once the SIRS report lands, the board's job shifts to communication and scheduling: getting the required disclosures to owners, budgeting the newly mandatory reserve contributions, and deciding whether a special assessment, a loan, or a longer funding ramp makes sense for any existing shortfall. This is the part that eats board volunteers alive, because it's paperwork-heavy and deadline-driven on top of everyone's regular job and family life. This is exactly the gap our $199 one-time Board Compliance Kit is built for: it organizes the milestone and SIRS deadlines specific to your building's age and coastal zone, tracks what's been filed versus what's still owed, and drafts the owner notices your documents likely require. It doesn't replace your engineer, your attorney, or your reserve specialist; it organizes what they hand you so nothing slips through a board transition or a missed mailing deadline. Start at /board-kit-builder if that's the piece you're missing. For the funding side specifically, Florida did pass some relief provisions letting associations phase in reserve contributions under certain conditions; see florida condo reserve fund relief for what's changed and what boards still can't waive.
What happens if our reserves fall short?
If the SIRS or reserve study shows a shortfall, the board generally has three levers: raise regular assessments over time, levy a special assessment for the gap, or take out a bank loan secured against future assessments. Most associations end up using some blend of the three, because a pure special assessment large enough to close a big gap in one year is often more than owners can absorb. A special assessment big enough to cover a structural repair can run into the tens of thousands of dollars per unit in extreme cases (this happened at several older South Florida buildings after 2021), while a phased reserve increase spreads the same cost over years and is generally easier on owners' cash flow, though it takes longer to build the money. Our condo special assessment insurance piece covers whether insurance products can help offset the risk, and what they typically don't cover. What boards should not do is quietly under-fund and hope the next board deals with it. Since SIRS-covered components can no longer have their reserve funding waived or reduced by owner vote [1], a board that skips the contribution isn't just kicking the can. It's creating a statutory compliance gap that a future board, or a title company during a sale, will eventually surface.
Who actually performs a reserve study, and how do we find one in Miami?
A general reserve study (the broader, non-SIRS version) is typically performed by a reserve specialist, often credentialed as an RS (Reserve Specialist) through the Community Associations Institute, or by an engineering firm that does this work regularly. A SIRS, by contrast, must be performed by a Florida-licensed engineer or architect per Section 718.112(2)(g) [1]; a generalist reserve consultant without that license cannot legally sign off on the SIRS. Check any engineer or architect's license status and disciplinary history directly through DBPR's public license search before you sign a contract. Ask for their SIRS-specific experience, more than general engineering credentials, since the report format and required components are new enough (the mandate phased in for reports due by December 31, 2024, with funding fully in effect after) that not every licensed engineer has done many of them yet. For a straightforward comparison of what a general reserve study covers versus what a SIRS legally requires, our reserve study for condo association guide lays out the component list side by side.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment of a building's major shared components (roof, plumbing, structure, paving, elevators) and the money needed to replace them over time. It includes a physical inspection and a funding plan, usually projected 20 to 30 years out, so the association can budget contributions instead of relying on surprise special assessments.
What is a reserve study for an HOA?
For an HOA, a reserve study covers components the association itself owns, like roads, clubhouses, pools, and gates, not individual homes. It estimates remaining life and replacement cost for each and builds a savings plan. Florida doesn't statutorily mandate this for most HOAs the way it does for condos, but it's widely considered best practice.
What is an HOA assessment?
An HOA assessment is the mandatory fee an association charges owners to cover shared expenses like landscaping, insurance, and reserve contributions, billed monthly or annually per the governing documents. It's distinct from a special assessment, which is a one-time charge for an unexpected or large expense outside the regular budget.
How much should an HOA have in reserves?
There's no fixed statewide dollar figure; the right amount depends on your specific component inventory and remaining useful life, which is exactly what a reserve study calculates. Industry practice generally treats 70% funded (current reserves versus ideal reserves) as healthy and under 30% funded as a warning sign of an approaching special assessment.
How much does a reserve study cost in Florida?
Basic reserve studies for smaller associations typically run $2,500 to $7,000. Larger buildings or those requiring a licensed engineer for a structural integrity reserve study (SIRS) commonly pay $8,000 to $25,000 or more, especially in high-demand markets like Miami-Dade where engineer availability is tight around SIRS and milestone inspection deadlines.
Are HOA and condo special assessments tax deductible?
Generally no, for owner-occupied homes. The IRS treats special assessments like regular HOA dues, as a personal or capital expense, not a deduction, per IRS Publication 530. Exceptions can apply for rental properties (partial deduction) or for assessments tied to capital improvements (added to cost basis). Confirm with a CPA for your situation.
What's the difference between a reserve study and a SIRS?
A general reserve study covers everything the association wants funded, cosmetic items included, and isn't legally mandated for most Florida condos. A structural integrity reserve study (SIRS) is a narrower, statutory requirement under Florida Statute 718.112 covering only structural and life-safety components, mandatory for most condos three stories and taller.
When does a Florida condo need its first SIRS?
At 30 years old for most buildings, or 25 years old if the building sits within three miles of a coastline, then every 10 years after that. Given Miami-Dade's coastal geography, a large share of the county's condo buildings fall under the 25-year trigger rather than the 30-year one.
Can our association still waive reserve funding by owner vote?
Not for components covered by a SIRS. Florida Statute 718.112(2)(f) states reserve funds for SIRS-required items "may not be waived or reduced" by the membership, a change from the pre-2022 rules that allowed broader waivers. Non-SIRS, cosmetic reserve items may still have more flexibility depending on your documents.
Who is legally allowed to perform a SIRS in Florida?
Only a Florida-licensed engineer or architect can perform a structural integrity reserve study, per Section 718.112(2)(g). A general reserve specialist without that license can prepare a traditional reserve study but cannot legally sign off on the statutory SIRS report.
Does Miami-Dade have extra reserve or inspection requirements beyond state law?
Miami-Dade runs its own longstanding building recertification program (40-year, then every 10 years) under county code, which operates alongside but isn't identical to the statewide milestone inspection and SIRS laws. Boards should confirm both sets of deadlines separately with their engineer and the county building department.
What happens if a reserve study finds our reserves are underfunded?
The board typically chooses among raising regular assessments over time, levying a special assessment, or taking a loan secured against future dues, often blending the three. Boards can no longer simply vote to waive funding for SIRS-covered components, so a documented shortfall now needs an actual funding plan, more than a deferral.
