Condo reserve fund requirements: what Florida boards must fund

Last updated 2026-07-24

What is a reserve study?

A reserve study is a physical inspection and financial forecast, done together, that tells a condo or HOA board two things: what shape the building's major components are in, and how much money the association needs to set aside each year to pay for replacing them without a surprise bill. A typical reserve study has two halves. The physical analysis looks at every major common-element component (roof, pavement, pool, elevators, structural elements, plumbing risers, and so on), estimates its remaining useful life, and prices out replacement at today's rates. The financial analysis then models a funding plan, usually a 20 to 30 year projection, that shows what the reserve balance should be each year to hit zero right when a component needs replacing, not before, not after. In Florida condos, this isn't optional paperwork anymore for buildings covered by the Structural Integrity Reserve Study (SIRS) requirement. Under Fla. Stat. § 718.112(2)(g), condo associations with buildings three stories or higher must have a SIRS performed for specific structural components: roof, structure (load-bearing walls and other primary structural members), fireproofing and fire protection systems, plumbing, electrical, waterproofing and exterior painting, windows and doors, and any other item with a deferred maintenance expense over $10,000 that, if left unaddressed, threatens habitability ^[1]. The SIRS has to be done or ratified by a licensed engineer or architect ^[1]. A board can't just eyeball the roof and write a number down. This is one reason a reserve study for a Florida condo now costs more and takes longer to schedule than the informal reserve estimates boards used to get by with.

What is a reserve study for an HOA?

For a homeowners association (not a condo), a reserve study serves the same core purpose, funding a plan to replace shared components like roofs, roads, clubhouses, and pools, but the legal requirement is much lighter than what condos now face. Florida HOAs are governed by Fla. Stat. ch. 720, not ch. 718, and as of the 2024 statutory framework, ch. 720 does not impose a SIRS-style mandatory structural reserve study on single-family or townhome HOAs the way ch. 718 does for condos three stories and up. Many HOAs still choose to commission a hoa reserve study voluntarily, because underfunded reserves are the single biggest cause of large surprise special assessments, and lenders (including Fannie Mae) increasingly ask HOAs about reserve funding levels during condo/HOA project reviews. If your community is a condo of any height, don't assume ch. 720 rules apply to you. If your community is a straight HOA (detached homes, no shared structural building components), the SIRS mandate doesn't apply, but the same math problem does: components wear out, replacement costs money, and a board with no study has no real basis for its reserve line items.

What is an HOA assessment (and what is an HOA special assessment)?

An assessment is the money a condo or HOA charges owners to run the association. Regular assessments are the recurring dues, usually monthly or quarterly, that cover operating costs (insurance, landscaping, management fees) and reserve contributions. A special assessment is a one-time or short-term additional charge, on top of regular dues, levied when the association needs money it doesn't have on hand, usually because reserves were underfunded or an unexpected repair (storm damage, a failed pipe, a milestone-inspection-driven repair) came up. Florida condo boards can levy a special assessment without a full membership vote in most cases, the board just has to follow notice requirements in the bylaws and Fla. Stat. § 718.112, and the assessment has to be for a legitimate common-element purpose. This is exactly the scenario the SIRS requirement is designed to prevent: a board that has been fully funding reserves according to an engineer-backed study shouldn't need a five-figure special assessment when the roof finally needs replacing, because the money is already there. A hoa special assessment works similarly for non-condo communities, governed by ch. 720 and the association's declaration. The dollar amounts and voting thresholds required to approve one vary a lot by governing document, so this is a spot where you need your association's actual declaration and counsel, not a generic answer.

How much should an HOA (or condo) have in reserves?

There's no single dollar figure or percentage that's legally required across the board, the honest answer is: enough to fund full replacement of every major component on schedule, per the reserve study, with zero deferred (underfunded) lines for the structural items a SIRS covers. For Florida condos under the post-2024 law, the target isn't a percentage, it's a specific number generated by the SIRS itself. The statute requires associations to reserve, at minimum, the amount recommended in the SIRS for each structural component category ^[1]. Boards used to be able to ask owners to vote to waive or reduce reserves entirely; that option is gone for SIRS-covered structural components as of the deadlines set in Fla. Stat. § 718.112(2)(g) and § 718.103, and DBPR has published guidance confirming associations cannot vote to waive or use SIRS reserves for anything other than their designated purpose ^[2]. For non-structural reserve items (painting the clubhouse, resurfacing a tennis court, replacing pool furniture) and for HOAs generally, owners can typically still vote each year to fully fund, partially fund, or waive reserves, subject to whatever the declaration and ch. 718 or ch. 720 allow. That flexibility is exactly why so many Florida buildings went into 2023 with reserve accounts at pennies on the dollar, and why the legislature tightened the rules after the Champlain Towers South collapse in Surfside in 2021. A rough industry rule of thumb some reserve specialists use is targeting a reserve "percent funded" of 70% or higher relative to the fully-funded ideal balance, though this isn't a Florida statutory threshold, it's a common benchmark cited by reserve study firms and community association trade groups. Treat it as a sanity check, not a legal target.

What are HOA / condo reserve requirements under Florida law?

Florida's ch. 718 reserve rules changed substantially after Surfside. Here's the current framework in plain terms. Condo buildings three stories or higher must complete a Milestone Inspection (structural inspection by a licensed engineer or architect) at 30 years from the certificate of occupancy (25 years if within 3 miles of the coast), and every 10 years after that, under Fla. Stat. § 553.899 ^[3]. That inspection feeds directly into the SIRS process, because the SIRS financial plan needs current, accurate data on component condition. Separately, the SIRS itself has to be completed by December 31, 2024 for most existing associations (with some phase-in nuance depending on when the association was created and DBPR guidance), and updated at least every 10 years ^{[1] [2]}. Once a SIRS exists, the board must include SIRS-based reserve funding in the annual budget starting with the fiscal year following the deadline, and members cannot vote to waive or reduce those specific reserve line items ^[1]. The legislature has amended these deadlines and details more than once since 2022 (SB 4-D, then further tweaks in 2023 and 2024 legislative sessions), so exact dates and thresholds are worth confirming directly with your association's counsel and your county building department before you set a budget around them. DBPR's Division of Florida Condominiums, Timeshares, and Mobile Homes maintains current guidance and FAQs on its site ^[2]. There's also been legislative relief activity: lawmakers have discussed and in some cases passed temporary flexibility on funding timelines for associations facing steep special assessments, so check florida condo reserve fund relief for the latest on any extension or phase-in adjustments before assuming your original deadline still stands unchanged.

How much does a reserve study cost?

Reserve study pricing in Florida varies mostly by building size, number of components, and whether it's a full SIRS (which requires a licensed engineer or architect) versus a standalone financial reserve study for non-structural items. Industry pricing reported by reserve study firms and community association management sources generally runs from roughly $3,000 to $10,000+ for a mid-size condo SIRS (say, 50 to 150 units), with larger or more complex buildings, multiple structures, or coastal high-rises running higher, sometimes well into five figures. A basic HOA reserve study covering common non-structural amenities for a smaller community can run cheaper, often in the $1,500 to $5,000 range depending on scope. These are market-rate estimates from practitioner and industry sources, not a statutory fee schedule, actual quotes vary by region and the number of buildings on a single parcel. What drives cost up: number of separate structures needing individual assessment, deferred maintenance already visible (more investigation time), and whether the engineer needs destructive or invasive testing to assess things like rebar corrosion in concrete. What doesn't reliably drive cost: building age alone, a well-maintained 1985 building can be cheaper to study than a poorly-maintained 2005 one. Boards should get at least two or three quotes and confirm the firm's engineer or architect holds an active Florida license, which you can verify through the Florida Department of Business and Professional Regulation's license verification tool for engineers. A reserve study for condo association buildings should be treated as a recurring line item (every 10 years minimum under the SIRS rule), not a one-time expense, so budget for the next cycle now.

Are HOA special assessments tax deductible?

For most owners, no. Special assessments paid to a condo or HOA are generally not deductible on a personal federal income tax return, the IRS treats them similarly to regular association dues, which are considered a personal (non-deductible) living expense for an owner-occupied home under general IRS guidance on itemized deductions ^[4]. There are narrow exceptions. If the assessment is for a capital improvement to a property you rent out (a rental unit you own), the portion allocable to that unit may be added to your cost basis or depreciated as a capital improvement rather than deducted immediately, consistent with IRS Publication 527 guidance on rental property expenses ^[4]. If part of your home is used for a qualifying home office, a portion of the assessment tied to that business-use percentage may be deductible as a business expense, per the home office rules in IRS Publication 587 ^[5]. This is genuinely a case-by-case tax question. The honest answer is: ask a CPA who has your specific facts (rental use, home office use, or personal residence), don't rely on a board notice or a general article, including this one, to make that call for your return.

How does the SIRS requirement change what boards must budget for?

The biggest practical shift is that boards no longer get to choose whether to fund structural reserves. Before the post-Surfside reforms, a majority of owners at a meeting could vote every year to waive or reduce reserve funding, and a lot of associations did exactly that to keep monthly dues low. That option is now closed for SIRS-covered components. This means budget season looks different. Once a SIRS is complete, the board has to build the SIRS-recommended contribution into the operating budget as a required line item, not a discretionary one, per Fla. Stat. § 718.112(2)(f) as amended ^[1]. If that number is a big jump from what owners have been paying, and for a lot of Florida buildings that had waived reserves for years, it is a big jump, boards need to communicate that early, not drop it in the annual budget mailer with no warning. This is where organizing the moving parts (milestone inspection deadline, SIRS deadline, budget calendar, owner notices) becomes its own project. A $199 one-time Building-Specific Board Compliance Kit (see the board kit builder) can help a board track which deadlines apply to its specific building height and coastal zone and keep the paperwork and owner communications organized, but it doesn't replace the licensed engineer who has to actually perform the SIRS or milestone inspection, and it doesn't tell your board whether your specific reserve numbers are adequate. That's an engineering and legal call, not a scheduling one.

What happens if a board doesn't fund reserves properly?

Short term, nothing dramatic usually happens right away, underfunded reserves don't trigger an automatic fine. Long term, the risk is exactly what Surfside exposed: deferred structural maintenance that eventually requires either a catastrophic special assessment, a building closure, or in the worst case, a safety failure. Under current law, once a SIRS identifies a structural reserve requirement, the board has an affirmative statutory duty to fund it, and directors can face exposure for failing to follow the statute, though the specifics of director liability depend on the association's insurance, its declaration, and general fiduciary-duty case law under Florida corporate and condo statutes. DBPR also has enforcement authority over condo associations and can investigate complaints related to reserve and financial reporting violations ^[2]. The more common real-world failure mode isn't a lawsuit, it's a special assessment that blindsides owners, some of whom can't afford it and are forced to sell at a loss, or a building that can't get milestone-inspection repairs done on time and faces habitability questions from the county. Boards that get ahead of this, funding reserves per the SIRS from year one, communicating the plan clearly, and keeping milestone and SIRS paperwork organized, avoid almost all of it.

How does this differ for older buildings versus newer ones?

Age drives both the inspection timeline and the reserve math, but not in a simple straight line. Under Fla. Stat. § 553.899, the milestone inspection trigger is 30 years from the certificate of occupancy for most buildings, but drops to 25 years if the building is within 3 miles of the coastline, because of the accelerated corrosion and weathering risk from salt air ^[3]. A 1970s coastal high-rise may already be well past two full milestone cycles; a 2015 inland mid-rise won't hit its first milestone until the mid-2040s. Older buildings generally need bigger reserve contributions sooner, simply because more components are closer to end-of-life simultaneously (roof, plumbing risers, electrical panels installed decades ago often fail around the same window). Newer buildings have more runway, but the SIRS still has to be done on the same 3-story-and-up, 10-year-update cycle regardless of age, there's no age exemption from the SIRS requirement itself once a building crosses the height threshold.

How do reserve requirements compare, condo vs. HOA vs. co-op?

Structure type	Governing statute	Mandatory SIRS?	Can owners waive structural reserves?
Condo, 3+ stories	Fla. Stat. ch. 718	Yes, for structural components [1]	No, for SIRS-covered items
Condo, 1-2 stories	Fla. Stat. ch. 718	No SIRS mandate (still has general reserve rules)	Generally yes, subject to ch. 718 votes
HOA (detached/townhome)	Fla. Stat. ch. 720	No SIRS mandate	Yes, per declaration and ch. 720
Cooperative	Fla. Stat. ch. 719	Similar structural reserve provisions apply to co-ops under parallel 2022-2024 reforms	No, for structural items, confirm current text with counsel	The practical takeaway: height is the trigger, not building type alone. A 3-story condo has real, non-waivable structural reserve obligations that a 3-story HOA-governed building (if such a structure existed under ch. 720 rather than 718) would not have under the same statute. Always confirm which chapter actually governs your community before assuming a rule applies.

What should a board do in year one after getting its first SIRS?

Start with the number, not the messaging. Get the SIRS-recommended annual contribution for each structural component, compare it to current reserve balances and current monthly assessments, and calculate the real gap in dollars, not percentages, dollars are what owners will ask about. Then build a multi-year transition plan if the gap is large. Fla. Stat. § 718.112 doesn't require boards to hit full SIRS funding in year one in every case; some associations phase in the increase over a couple of budget cycles if the declaration and any legislative relief provisions allow it, this is exactly the kind of judgment call that needs association counsel, since phase-in flexibility has shifted with amendments since 2022 and isn't identical for every association. Finally, document everything: the SIRS report itself, the milestone inspection report if one was done, board meeting minutes where the budget was approved, and the notice sent to owners. If DBPR or a future board ever needs to show the reserve decision was made properly, a clean paper trail matters more than almost anything else in a compliance dispute.

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, elevators) paired with a multi-year financial plan showing how much an association needs to save each year to replace them on schedule. Florida condos 3+ stories must have a specific version, the SIRS, done by a licensed engineer or architect under Fla. Stat. § 718.112.

What is a reserve study for an HOA?

For an HOA, a reserve study serves the same funding-planning purpose as it does for condos, but Florida's mandatory SIRS requirement under ch. 718 applies to condo buildings, not standard HOAs under ch. 720. Many HOAs still commission voluntary reserve studies because underfunded reserves are the leading cause of large surprise special assessments.

What is an HOA assessment?

An HOA assessment is money the association charges owners, either as regular recurring dues covering operations and reserves, or as a special assessment, a one-time or short-term extra charge for costs reserves don't cover. Amounts and approval rules come from the association's declaration and Florida Statutes ch. 720 for HOAs or ch. 718 for condos.

How much should an HOA have in reserves?

There's no single statutory dollar figure for HOAs under ch. 720. The honest target is whatever a current reserve study says is needed to fully fund replacement of major components on schedule. Some reserve specialists use 70% funded (relative to the fully-funded ideal) as a rough benchmark, but that's an industry rule of thumb, not a Florida legal requirement.

How much should a condo have in reserves in Florida?

For structural components covered by the SIRS (roof, structure, plumbing, electrical, waterproofing, windows and doors, fireproofing), Florida condos 3+ stories must fund the exact amount the SIRS recommends, with no owner vote to waive it, per Fla. Stat. § 718.112(2)(g). Non-structural reserve items can still be voted down by owners in many cases.

How much does a reserve study cost in Florida?

Industry pricing generally runs roughly $3,000 to $10,000+ for a mid-size condo SIRS, higher for large or complex coastal high-rises, and lower (often $1,500 to $5,000) for a basic non-structural HOA reserve study. Exact cost depends on number of components, building size, and whether invasive testing is needed.

Are HOA or condo special assessments tax deductible?

Generally no, for a personal residence, the IRS treats special assessments like non-deductible personal living expenses. Exceptions exist for rental properties (added to cost basis or depreciated per IRS Publication 527) or a qualifying home office (partial business deduction per IRS Publication 587). Confirm your specific situation with a CPA, since it depends on how the property is used.

What triggers a milestone inspection in Florida?

A milestone structural inspection is required at 30 years from the certificate of occupancy for most condo and co-op buildings 3+ stories, or 25 years if the building sits within 3 miles of the coastline, under Fla. Stat. § 553.899. Inspections repeat every 10 years after the first one.

Can owners still vote to waive condo reserves in Florida?

Not for SIRS-covered structural components (roof, structure, plumbing, electrical, waterproofing, windows/doors, fireproofing). Owners lost the ability to waive or reduce those specific reserve lines under the post-2022 reforms to Fla. Stat. § 718.112. Non-structural reserve items may still be subject to a waiver vote depending on the association's documents.

What happens if my condo board doesn't complete the SIRS on time?

There's no single automatic penalty spelled out for every scenario, but DBPR has enforcement authority over condo associations and can investigate complaints tied to reserve and financial reporting violations. Practically, missing the SIRS deadline delays proper budgeting, exposes the board to liability questions, and often forces a rushed, more expensive special assessment later.

Does a co-op have the same reserve requirements as a condo in Florida?

Florida cooperatives fall under ch. 719, which has parallel structural reserve provisions enacted alongside the ch. 718 condo reforms after Surfside. The general framework (structural reserve study, non-waivable structural funding) is similar, but exact statutory cross-references have shifted with amendments, so confirm current ch. 719 text with association counsel.

Is a reserve study the same thing as a milestone inspection?

No. A milestone inspection (Fla. Stat. § 553.899) is a structural safety check by a licensed engineer or architect at 30 (or 25 coastal) years and every 10 years after. A SIRS (Fla. Stat. § 718.112) is a reserve funding study that uses similar component data but focuses on financial planning, not a pass/fail safety verdict.
