TL;DR
There's no flat percentage or dollar figure that applies to every building. Florida law (F.S. 718.112) now requires condo associations to fund reserves at 100% of what a licensed reserve study says is needed for roofs, structure, plumbing, electrical, waterproofing, fireproofing, elevators, and any item over $10,000, with no more waivers or underfunding votes after the December 31, 2024 deadline.
How much should a condo association have in reserves?
The honest answer is: whatever your reserve study says you need, not some round number pulled from a national average. Florida stopped letting associations guess. Under section 718.112(2)(f) of the Florida Statutes, condo associations must fund reserves for certain components at a level equal to 100% of the amount a reserve study determines is necessary [1]. There's no statutory floor like "10% of the budget" or "$50,000 minimum." The number comes out of a building-specific calculation done by a licensed engineer, architect, or reserve specialist. That said, boards want a sanity check before they hire anyone. As a rough industry benchmark, Community Associations Institute research and reserve-study firms have long suggested associations should be funding reserves at somewhere between 70% and 100% of the fully-funded level to avoid special assessments, with anything under 30% funded considered a red flag by most reserve professionals. Florida just made the top of that range mandatory for the components the statute lists. So the practical answer for a Florida condo board in a building 3 stories or taller: get the reserve study done, then fund at 100% of what it says for structural components, and don't let the board waive or reduce that funding. Waivers for those statutory components are gone as of the end of 2024 [2].
What is a reserve study?
A reserve study is a physical inspection and financial analysis of a building's major components, done to figure out how much money the association needs to be setting aside each year so it can pay for roof replacement, repaving, repainting, plumbing repairs, and similar big-ticket items without a surprise special assessment. A real reserve study has two halves. The physical analysis inventories every major common-element component (roof, pavement, structure, plumbing, electrical, elevators, painting, and so on), estimates each one's remaining useful life, and estimates the cost to repair or replace it. The financial analysis then models the association's current reserve balance against future costs and recommends an annual contribution schedule, usually using either a straight-line (component) method or a pooled (cash-flow) method. In Florida, for buildings covered by the milestone inspection and SIRS requirements, the study has to be prepared or verified by someone qualified under section 718.112(2)(g), generally a licensed engineer or architect for the structural integrity reserve study (SIRS) piece [1]. See our reserve study guide for how the inspection and paperwork actually flow together.
What is a reserve study for an HOA?
For a homeowners association, the mechanics of a reserve study are basically the same as for a condo, but the legal requirement is different. HOAs in Florida are governed by Chapter 720, not Chapter 718, and Chapter 720 does not currently impose the same mandatory 100%-funding, no-waiver rule that applies to condos under 718.112 [3]. Many HOAs still get reserve studies done voluntarily, or because their governing documents (declaration, bylaws) require it, because lenders ask for one, or because the board simply wants to avoid a $20,000 special assessment landing on homeowners with no warning. A reserve study for an HOA typically covers roads, drainage, clubhouse or amenity structures, pools, fencing, and irrigation systems, whatever common-element infrastructure the association is responsible for maintaining. The output looks the same: a component list, remaining life estimates, and a recommended funding schedule. If you're on an HOA board wondering whether you're required to do this, the honest answer is: check your declaration and bylaws first, then confirm with your association's counsel, because the statutory landscape for HOAs is looser than for condos and it's easy to assume a condo rule applies to you when it doesn't. Our HOA reserve study page walks through the difference in more detail.
What is an HOA assessment (and what is a condo assessment)?
An assessment is simply the money an association charges owners to cover its budget. Every association, condo or HOA, uses assessments to fund operating expenses and reserves. There are two basic kinds: regular assessments and special assessments. Regular assessments are the recurring dues owners pay, usually monthly or quarterly, set by the annual budget. Special assessments are one-time charges levied when the regular budget and reserves aren't enough to cover a specific need, a new roof after storm damage, a required structural repair identified in a milestone inspection, litigation costs, or a shortfall the board didn't plan for. Under Florida Statutes 718.112(2)(f), condo boards can no longer vote to waive or reduce reserve funding for the statutory components (roof, load-bearing walls, floor, foundation, fireproofing/fire protection, plumbing, electrical, waterproofing, and any other item costing more than $10,000 that the association is responsible for) [1]. That single change is why so many buildings are now facing special assessments: years of underfunded reserves are catching up all at once. If your board is staring down one of these, our HOA special assessment and condo special assessment insurance pages cover how to structure and, in some cases, insure against them.
How much should an HOA have in reserves?
There's no Florida statute mandating a specific reserve percentage for HOAs the way there is for condos. So this comes down to what your reserve study recommends and how much risk your board is willing to carry. Most reserve professionals use "percent funded" as the benchmark: your current reserve balance divided by the theoretical fully-funded balance for all components at their current age. National reserve-study data (aggregated by firms like Association Reserves, which publishes an annual State of Reserves report) has repeatedly shown the average community association nationwide sits somewhere in the 30% to 40% funded range, well below the 70%+ that specialists generally consider "healthy." Boards funded under 30% face materially higher odds of a special assessment within the next few years. A practical target many reserve specialists recommend for HOAs without a legal mandate: aim for at least 70% funded, and treat anything below 50% as a signal to raise dues or start planning a special assessment before a roof or road failure forces the issue. That's not law, it's professional judgment, so weigh it against your own budget and your homeowners' tolerance for dues increases.
How much does a reserve study cost?
For a condo association, reserve study costs vary a lot by building size, age, and complexity, but as a general range, expect somewhere between $3,000 and $15,000+ for a full reserve study on a mid-size to large condo building, with high-rises or buildings with complex structural components running higher. A basic "update" reserve study (no new site visit, just updated numbers) usually costs less than a full study with an on-site inspection. For Florida's structural integrity reserve study (SIRS), which is now mandatory for condo and cooperative buildings 3 stories or taller under section 718.112(2)(g), costs depend heavily on building size and whether it's combined with the milestone inspection. Some engineering firms bundle the milestone inspection and SIRS into a single site visit to save the association money, since both require a licensed engineer or architect physically examining the same structural components [1]. HOAs doing a voluntary reserve study for roads, amenities, and common infrastructure often pay less than a condo tower, sometimes in the $1,500 to $5,000 range for smaller communities, but this varies enormously depending on how much infrastructure the association owns. The real cost isn't the study itself, it's what happens if you skip it. A board that never gets a study, then gets hit with a mandatory SIRS finding a failing structural component, is looking at a special assessment that dwarfs whatever the study would have cost.
What triggered Florida's 100%-funding reserve requirement?
The short version: the Champlain Towers South collapse in Surfside in June 2021 killed 98 people and exposed how many Florida condo boards had been underfunding reserves and deferring structural maintenance for decades. The Florida Legislature responded with SB 4-D in 2022 and later refinements (including SB 154 in 2023), rewriting section 718.112 to require milestone structural inspections and mandatory, non-waivable reserve funding for structural components [2]. The key statutory deadlines: buildings 3 stories or higher had to complete their first SIRS by December 31, 2024, and mandatory 100% reserve funding for the statutory components kicked in starting with the first fiscal year beginning on or after that date [1]. Milestone inspections, separately, are required once a building hits 30 years of age (or 25 years if it's within 3 miles of the coast), and then every 10 years after, under section 553.899 [4]. As the Florida Senate's own bill analysis put it regarding SB 4-D, the legislation was designed to ensure buildings "maintain adequate reserves" and complete inspections "to determine the structural integrity" of aging condominiums [2]. Confirm current deadlines and any local extensions with your association's counsel and county building department, since some details have shifted since the original 2022 legislation and the Legislature has continued to adjust implementation timelines.
Are HOA special assessments tax deductible?
Generally, no, not for the individual owner claiming a personal deduction, and this is one of the most misunderstood parts of assessment planning. Special assessments paid to your HOA or condo association for capital improvements or reserve shortfalls are typically treated like a capital improvement to your property, not a deductible expense, for a primary residence. The IRS generally treats regular HOA dues and special assessments on a personal residence as nondeductible personal expenses, similar to how home maintenance costs aren't deductible [5]. There are two situations where the tax treatment can differ: if the unit is a rental property, ordinary and necessary assessments related to operating or maintaining the property may be deductible as a rental expense, and assessments for capital improvements may need to be added to your cost basis rather than deducted immediately, per IRS Publication 527 guidance on rental property expenses [6]. If the assessment covers casualty-related repairs (storm damage, for example) there can be narrower exceptions tied to casualty loss rules. This is genuinely a case where you want your own CPA or tax preparer, not a board member's guess, because the deductibility depends on how the assessment is characterized (repair vs. capital improvement), whether the unit is a primary residence or rental, and current IRS rules that can shift year to year.
What happens if a condo board doesn't fund reserves at the required level?
Boards that ignore the 100% funding requirement for statutory reserve components are exposing themselves to real legal and financial risk, more than a hypothetical. Section 718.112 gives the Division of Florida Condominiums, Timeshares, and Mobile Homes (part of DBPR) authority to investigate complaints and enforce condominium recordkeeping and financial requirements, and unit owners can also bring their own claims when a board fails to follow statutory reserve obligations [7]. Beyond legal exposure, the practical risk is compounding. An underfunded reserve doesn't just sit flat, it gets worse every year components age without money being set aside, until the eventual bill (a full roof replacement, major concrete restoration, elevator modernization) lands as a special assessment far larger than what steady annual funding would have required. Boards that get caught flat-footed by a SIRS finding often end up choosing between a massive one-time assessment, high-interest reserve borrowing, or both. For buildings navigating an underfunded reserve situation, it's worth knowing that some limited relief mechanisms have been discussed at the state level; see our page on florida condo reserve fund relief for what's actually available versus what's just been proposed.
How do boards figure out the right reserve number for their specific building?
Start with the reserve study, not with a guess or a board member's spreadsheet from five years ago. A current reserve study, updated at least every few years (many management contracts and best practices call for an update every 3 to 5 years, or sooner after a major repair), gives the board a defensible, professional basis for its funding decisions. From there, the board's job is mostly administrative discipline: adopting the recommended contribution schedule into the annual budget, making sure reserve funds are held in a separate account (not commingled with operating funds) as required for statutory reserves, and documenting the decision-making so owners and, if it comes to it, DBPR or a court can see the board acted on professional advice rather than guessing. This is where a lot of volunteer boards get stuck, not because the math is hard, but because tracking which inspection is due when, which components are covered by the SIRS, and which contribution schedule applies to which fiscal year turns into a scheduling and paperwork problem on top of a financial one. That's the gap our $199 one-time Board Compliance Kit is built to close: it organizes your building's specific milestone and SIRS deadlines, reserve funding checkpoints, and owner communication templates into one place, so the board isn't relying on memory or a scattered email chain. It doesn't replace your engineer or your reserve specialist, it just keeps the compliance calendar from falling apart between meetings.
What's the difference between a reserve study and a milestone inspection or SIRS?
These are three different things that often get lumped together, and mixing them up causes real confusion for boards. A milestone inspection is a structural safety inspection required under section 553.899 once a building reaches 30 years old (25 if within 3 miles of the coast), repeated every 10 years, done by a licensed engineer or architect, and it produces a phase 1 (and if needed, phase 2) structural report [4]. A SIRS (structural integrity reserve study) is the financial planning document required under section 718.112(2)(g) that looks specifically at the structural components (roof, load-bearing walls, primary structural systems, fireproofing, plumbing, electrical, waterproofing, and decking) and determines the reserve funding needed for each [1]. A general reserve study is broader and can cover non-structural components too (painting, pavement, amenities), and it's not always legally mandated the way SIRS is for qualifying condo buildings. Many firms combine the site visit for milestone inspections and SIRS since both need a licensed professional physically examining the same structural elements, which can save the association money on duplicate engineering visits. Check our milestone inspections coverage and SIRS guides hub for how these two requirements interact on your specific timeline.
Frequently asked questions
How much should a condo association have in reserves in Florida?
There's no flat dollar figure or percentage set by statute. Florida law requires condo associations to fund reserves at 100% of what a licensed reserve study determines is necessary for structural components like roofs, plumbing, electrical, and waterproofing, per Florida Statutes 718.112(2)(f). The exact number is building-specific and comes from your reserve study, not a national average.
What is a reserve study?
A reserve study is a physical inspection and financial analysis of a building's major shared components, done to estimate remaining useful life and replacement cost, then translated into a recommended annual contribution schedule so the association isn't caught short when a roof, elevator, or plumbing system needs replacement.
What is a reserve study for an HOA?
It's the same basic process as a condo reserve study, applied to whatever common infrastructure the HOA owns, roads, drainage, clubhouses, pools, fencing. Unlike condos under Chapter 718, Florida HOAs under Chapter 720 aren't currently subject to the same mandatory 100%-funding, no-waiver requirement, so many HOA reserve studies are done voluntarily or per the association's own governing documents.
What is an HOA assessment?
An HOA assessment is money the association charges owners to cover its budget, either as regular recurring dues or a one-time special assessment for an unexpected or underfunded expense. Special assessments become common when reserves weren't funded high enough to cover a major repair, like a roof replacement or a structural repair flagged by an inspection.
What are HOA assessments used for?
HOA assessments fund two buckets: day-to-day operating costs (landscaping, insurance, management fees, utilities for common areas) and reserves for future big-ticket replacements (roofs, paving, major systems). Special assessments specifically cover shortfalls or emergencies the regular budget and reserves didn't anticipate, like storm damage or a newly discovered structural issue.
How much does a reserve study cost for a condo association?
Full reserve studies for mid-size to large Florida condo buildings generally run from roughly $3,000 to $15,000 or more, depending on building size, age, and complexity. SIRS costs vary similarly and are sometimes bundled with the milestone inspection site visit since both require a licensed engineer or architect to examine the same structural components.
Are HOA special assessments tax deductible?
Generally no, for a primary residence, the IRS treats HOA special assessments as nondeductible personal expenses similar to home maintenance costs. Exceptions can apply for rental properties, where ordinary assessments may be deductible as a rental expense and capital-improvement assessments may need to be added to your cost basis. Confirm with a CPA since treatment depends on your specific situation.
What is the minimum reserve funding percentage required by Florida law?
Florida law doesn't set a minimum percentage below 100%. Since the first fiscal year beginning on or after December 31, 2024, condo associations must fund reserves at 100% of the amount their reserve study determines is necessary for the statutory structural components, with no board waiver option for those items, under Florida Statutes 718.112(2)(f).
Can a condo board still waive reserve funding in Florida?
No, not for the statutory structural components. As of the fiscal year beginning on or after December 31, 2024, condo boards and unit owners can no longer vote to waive or reduce reserve funding for roofs, load-bearing walls, floors, foundations, fireproofing, plumbing, electrical systems, waterproofing, or any component costing over $10,000, per Florida Statutes 718.112(2)(f).
What's the difference between a reserve study and a SIRS?
A SIRS (structural integrity reserve study) is a specific, statutorily-required study under Florida Statutes 718.112(2)(g) covering only structural components for qualifying condo buildings. A general reserve study is broader, can be voluntary, and may cover non-structural items like painting, pavement, and amenities in addition to structural ones.
Do HOAs in Florida have to follow the same reserve rules as condos?
No. The mandatory 100%-funding and no-waiver reserve rules apply to condo and cooperative associations under Florida Statutes Chapter 718. HOAs are governed by Chapter 720, which doesn't currently impose that same statutory mandate, though individual HOA declarations or bylaws may require reserve studies or specific funding levels on their own.
How often should a condo association update its reserve study?
Most reserve professionals and many governing documents recommend updating a reserve study every 3 to 5 years, or sooner after a major repair, storm event, or significant change to a component's condition. Florida's SIRS requirement itself is tied to the milestone inspection cycle, generally every 10 years once a building reaches the statutory age threshold.
What happens if a Florida condo doesn't have enough in reserves when a repair is needed?
The board typically has to levy a special assessment to cover the shortfall immediately, since the repair (a failing roof, a structural issue from a milestone inspection) can't wait. Boards sometimes also pursue reserve loans or lines of credit, but both routes usually cost owners more than steady, properly funded annual reserve contributions would have.
