TL;DR
Florida condo associations 3+ stories must fund reserves for structural components (SIRS items) at levels set by a reserve study, with no more waiving allowed as of December 31, 2024. HOAs (non-condo) generally set their own reserve policy under Chapter 720 unless the declaration says otherwise. A reserve study for a mid-size building typically costs $3,000 to $15,000+ depending on scope.
What is a reserve study?
A reserve study is a physical inspection and financial analysis of a building's major components (roof, paint, pavement, plumbing risers, elevators, and for condos, structural elements like load-bearing walls and waterproofing) done to estimate remaining useful life and the cost to repair or replace each item. The output is a funding schedule: how much money the association should be setting aside each year so it has cash on hand when the roof, or the parking garage deck, actually needs work. In Florida, reserve studies come in two flavors that matter a lot right now. There's the traditional financial reserve study that community association managers and reserve specialists have done for decades, covering things like paint, paving, and roofing. And there's the Structural Integrity Reserve Study (SIRS) created by SB 4-D and refined by SB 154, which is specific to condominiums and cooperatives 3 stories or taller and covers structural, load-bearing, and life-safety components [1]. A SIRS must be performed by a licensed engineer or architect, more than a reserve preparer [1]. These aren't the same document, and a lot of boards get this wrong. A general reserve study might tell you the roof needs replacing in 8 years. A SIRS tells you the roof, plus the primary structural members, the load-bearing walls, floor and foundation, exterior painting and waterproofing, windows and doors, and (if applicable) fireproofing, electrical systems serving common elements, plumbing, and the seawall, along with any other item with a deferred maintenance expense over $10,000 that would otherwise be a threat to life safety if left unaddressed [1]. For more on how the two differ in scope and who can prepare them, see our reserve study explainer.
What is a reserve study for an HOA?
For a homeowners association (governed by Chapter 720, not the condo statute in Chapter 718), a reserve study is the same basic idea, an engineer or reserve specialist inspects shared components and projects a funding schedule, but the legal requirements are much lighter than what condos face post-2024. Chapter 720 does not mandate a SIRS. HOAs are not subject to the structural inspection reserve requirements that apply to condominiums 3 stories and up under section 718.112 [2]. That means most single-family and townhome HOAs decide reserve funding policy through their own declaration, bylaws, and board vote, often following the same component-based methodology (roofs, roads, pools, clubhouses, retention ponds) but without a state-mandated study or a state-mandated funding floor. That said, many HOA declarations require an annual reserve study or a periodic update, and mortgage lenders (particularly for FHA and Fannie Mae approval of the community) often expect to see one. If your HOA has a clubhouse, private roads, or a stormwater system it's responsible for, skipping a study is a common way boards end up blindsided by a $40,000 pond bank repair with $6,000 in the bank. See our HOA reserve study guide for how HOAs typically structure this even without a legal mandate.
What is an HOA assessment, and what is a special assessment?
An HOA assessment is the recurring fee, usually monthly, quarterly, or annual, that every owner pays to fund the association's operating budget and reserves. It covers landscaping, insurance, management fees, utilities for common areas, and (ideally) contributions toward the reserve accounts for big future repairs. A special assessment is different. It's a one-time (or occasionally installment-based) charge levied outside the regular budget, usually because reserves came up short, an emergency repair is needed, or a new legal requirement (like SIRS-driven repairs) forces a large expense the reserve fund wasn't built to cover. Florida condo associations frequently turn to special assessments now because many buildings spent years waiving or underfunding reserves before the law tightened, and the post-Surfside legislative changes closed that option for structural items. Under Chapter 718, a board can levy a special assessment without a membership vote unless the declaration says otherwise, though notice requirements apply. For a full breakdown of how these are calculated, noticed, and legally challenged, see hoa special assessment and condo special assessment insurance if you're weighing whether insurance can offset the hit.
How much should an HOA (or condo) have in reserves?
There's no single dollar figure or percentage that applies to every association, and anyone who tells you a flat number ('you need 3 months of operating expenses' or '10% of your budget') is oversimplifying. The honest answer is: enough to match the funding schedule your reserve study produces, based on the actual age, condition, and replacement cost of your components. For Florida condos 3+ stories, the answer is now partly a legal one, more than a financial best practice. As of December 31, 2024, condominium and cooperative associations subject to the SIRS requirement can no longer vote to waive or reduce reserve funding for the structural items identified in the study, and reserves for those items must be funded based on the full estimated replacement cost with no pooling for those specific line items [1] [1]. That's a real change from the pre-2022 world, where boards routinely voted every year to keep reserves at 'whatever we can afford.' For everything outside the SIRS-mandated structural components, and for HOAs generally, associations still typically have more flexibility, using either a straight-line (cash) or pooled (component) reserve method. A rough industry rule of thumb from reserve study professionals is that a healthy reserve fund is funded to at least 70% of its 'fully funded' level (the amount you'd have if every component were reserved for at 100% of its calculated need), but this is an industry guideline from firms like Association Reserves, not a Florida statutory threshold. Below 30% funded is generally considered a red flag by reserve specialists and lenders alike. The practical move for a board: get the reserve study done, look at the 20-30 year funding plan it produces, and compare your current reserve balance against the 'fully funded' line for each component. If you're materially behind, that's the conversation to have with owners now, not after a special assessment notice goes out.
What do HOA and condo reserve requirements actually cover?
| SIRS mandatory | Yes, for buildings 3 stories+ | No | |
|---|---|---|---|
| Who can perform SIRS | Licensed engineer or architect only [1] | N/A | |
| Reserve waiver allowed | No, for SIRS structural items, as of Dec 31, 2024 [1] | Generally yes, by member vote per declaration | |
| Funding method for SIRS items | Full funding, no pooling | N/A | |
| State-mandated reserve study | Yes (SIRS) plus standard reserve items | No state mandate; often required by declaration or lender | |
| Governing statute | Fla. Stat. ch. 718 | Fla. Stat. ch. 720 | For buildings under 3 stories, or condos that aren't subject to SIRS, the older, more flexible reserve funding and waiver rules under 718.112 still largely apply, though boards should confirm current status with counsel since this law has been amended multiple times since 2022. |
For Florida condos, section 718.112(2)(f) specifies the reserve accounts a budget must include at minimum: roof, building painting, pavement resurfacing, and any other item with a deferred maintenance expense or replacement cost exceeding $10,000, plus, for buildings subject to SIRS, all the structural items identified in that study [1]. Reserves can no longer be used for purposes other than their intended component unless owners vote to approve a temporary transfer, and even then, structural SIRS reserves are exempted from being reduced or waived [1]. Here's a comparison of how condo and HOA reserve obligations differ under Florida law: | Requirement | Condo (Ch. 718, 3+ stories) | HOA (Ch. 720) |
How much does a reserve study cost?
Costs vary widely based on building size, number of components, and whether you need a basic financial reserve study or a full SIRS with structural engineering. As a general range, industry sources and reserve preparers commonly cite $3,000 to $15,000+ for a standard multi-component reserve study on a mid-size community, with larger or more complex properties (high-rises, multiple buildings, extensive amenities) running higher [1]. A SIRS specifically, because it requires a licensed engineer or architect to physically inspect structural components including load-bearing elements, waterproofing, and the building envelope, tends to run on the higher end of that range or above it, particularly for taller buildings or those with limited access (think seawalls, below-grade parking, or difficult roof geometry). Florida does not publish a fixed price schedule for SIRS because pricing is set by the private engineering and reserve firms performing the work, so getting 2-3 quotes from Florida-licensed engineers is worth the time, more than the cheapest bid. Don't confuse the SIRS inspection cost with the cost of the repairs it identifies. The study itself might cost $8,000. What it finds might cost $2 million. That's the number that drives the special assessment conversation, not the study fee. One thing that actually saves money and headaches: once you have the study, organizing the deadlines, funding schedule, and owner communication around it doesn't require another expensive consultant. A structured system, like the $199 Building-Specific Board Compliance Kit at /board-kit-builder, can help a board track SIRS deadlines, reserve line items, and required owner notices without paying a management company premium for basic organization. It doesn't replace the engineer or the reserve preparer, and it makes no compliance determination about your specific building. It just keeps the paperwork and dates straight.
Are HOA special assessments tax deductible?
For most owners, no. Special assessments paid to an HOA or condo association are generally not deductible on your federal income taxes if the property is your personal residence, because the IRS treats these payments similarly to home improvement costs or non-deductible personal expenses [3]. IRS Publication 530, which covers tax information for homeowners, does not list HOA assessments among deductible items for owner-occupied homes. There are two situations where the answer changes. If the unit is a rental property, special assessments used for repairs or maintenance are generally deductible as a rental expense in the year paid, and assessments used for capital improvements typically get added to your cost basis and depreciated instead of deducted outright, per general IRS rules on rental property expenses [4]. If part of your home is used for a qualifying home office, a portion of regular assessments may be deductible as a business expense. This is a tax question specific to your situation, and the correct answer depends on facts the IRS cares about (rental vs. primary residence, repair vs. capital improvement). Talk to a CPA before assuming either way, and don't take a board member's guess as tax advice, they're not qualified to give it any more than you are.
What happens if a Florida condo doesn't fund its SIRS reserves?
The law now requires it, so 'doesn't fund' isn't really an option anymore for buildings subject to SIRS, at least not legally. Since December 31, 2024, boards can no longer vote to waive, reduce, or use pooled/cash-basis accounting for the reserve items a SIRS identifies as structural [1]. The association must fund those specific components at their full calculated need. Practically, what happens when a board falls behind (because the SIRS just got completed and reserves are nowhere close to where they need to be) is usually a large special assessment, a reserve loan, or both. Florida doesn't cap how large a special assessment can be, though the declaration or bylaws may impose procedural requirements like notice periods or, in rarer cases, a membership vote threshold. Owners who can't pay face the same collection mechanisms as unpaid regular assessments: late fees, interest, and eventually a lien or foreclosure process under 718.116 [1]. Some associations are turning to bank loans secured against future assessment income to spread the structural repair cost over years instead of hitting owners with a single lump sum. That's a financing decision the board and its counsel need to work through carefully, since loan covenants can constrain future reserve and budget decisions.
How is a reserve study different from a milestone inspection or SIRS?
These three things get confused constantly, and they serve different legal purposes. A milestone inspection (Fla. Stat. 553.899) is a structural safety inspection required for condo and cooperative buildings 3 stories or taller, generally due at 30 years of age (25 years if within 3 miles of the coast), and again every 10 years after [5]. It answers: is the building structurally sound right now? A SIRS is a reserve funding study required for the same population of buildings, focused on future costs of structural components, due initially by December 31, 2024, for most existing associations [1]. It answers: how much money do we need, and when, to keep those structural components in good repair? A general reserve study is the broader financial planning document covering roofing, paving, painting, and other non-structural common elements, which associations have done for decades under 718.112, independent of the newer post-Surfside laws. It answers: how much should we be saving for everything else? They're related (the milestone inspection often feeds findings into the SIRS) but they're not interchangeable, and satisfying one doesn't satisfy the others. Boards juggling all three deadlines on different buildings often lose track of which report is due when; that's the exact problem a compliance tracking system is built to solve, though the inspections and studies themselves have to come from the licensed engineers, architects, and reserve specialists the statute actually requires.
Can a Florida association pool reserve funds across components?
Pooling means combining multiple reserve components into one shared fund rather than tracking each one (roof, paint, pavement) in a separate line item, giving the board flexibility to move money between categories as needed. Historically, Florida condo associations could choose pooled or straight-line reserve accounting for most components. That flexibility no longer applies to SIRS structural items. Under the current law, reserves for the components identified in a Structural Integrity Reserve Study must be funded based on the full estimated cost of deferred maintenance or replacement, without pooling, meaning each structural item needs its own fully calculated reserve, not a shared bucket [1] [1]. Non-structural components (like landscaping features or a clubhouse roof not tied to structural safety) may still be eligible for pooled treatment depending on how your reserve preparer sets up the schedule and what your declaration allows. If your association used pooled accounting before 2022 and hasn't updated its reserve schedule since the SIRS requirement took effect, that's worth flagging to your reserve preparer and association counsel directly, since an outdated funding structure can create both a legal exposure and a real cash shortfall.
Does an HOA reserve study cost more or less than a condo SIRS?
Generally less, because a standard HOA reserve study doesn't require the licensed engineer or architect involvement that a condo SIRS requires under Florida law [1]. HOA reserve studies are typically prepared by reserve specialists or community association management firms and focus on amenities, roads, roofs on common buildings (like a clubhouse), and infrastructure like retention ponds. Costs for an HOA reserve study commonly fall in a similar $2,000 to $10,000 range depending on the number of components and complexity, though very small HOAs (a handful of duplexes with limited common property) may pay less, and large master-planned communities with extensive amenities can pay considerably more. The real cost difference shows up on the repair side, not the study side. Because HOAs generally don't have structural components like load-bearing walls and building envelopes across dozens of units, and typically manage single-family or low-rise properties, the repair costs a reserve study surfaces tend to run lower per household than what a high-rise condo faces after a SIRS. That's a big part of why HOA special assessments, while still painful, rarely reach the six and seven-figure totals seen in condo SIRS-driven assessments.
Frequently asked questions
What is a reserve study?
A reserve study is a professional inspection and financial analysis of an association's major components (roofs, paving, structural elements, plumbing) that estimates remaining useful life and replacement cost, then produces a funding schedule showing how much the association should save each year to cover those future expenses without a large special assessment.
What is a reserve study for an HOA?
For a Chapter 720 homeowners association, it's the same basic financial and physical inspection process used by condos, but there's no Florida statutory mandate requiring it. Many HOA declarations or lenders require one anyway, and it typically covers roads, clubhouses, pools, and stormwater infrastructure rather than structural building components.
How much should an HOA have in reserves?
There's no fixed statutory dollar amount for HOAs under Chapter 720. The reasonable benchmark, per reserve industry standards, is funding to at least 70% of the 'fully funded' level calculated in a reserve study; below 30% funded is generally considered financially risky by reserve professionals and lenders.
How much should a condo have in reserves under Florida law?
For SIRS-mandated structural components in condos 3+ stories, Florida law requires full funding based on the study's calculated replacement cost, with no waiving or pooling allowed as of December 31, 2024. For non-structural items, the association's reserve schedule and board policy determine the target.
What is an HOA assessment?
An HOA assessment is the regular fee (monthly, quarterly, or annual) every owner pays to fund the association's operating budget and reserve accounts. It's distinct from a special assessment, which is a one-time or installment charge levied outside the normal budget to cover an unexpected or underfunded expense.
What are HOA assessments used for?
Regular assessments fund day-to-day operations (landscaping, insurance, management, utilities) and reserve contributions for future big-ticket repairs. Special assessments cover shortfalls, emergencies, or new legal obligations, like Florida's SIRS-driven structural reserve requirements, that the regular budget and reserves weren't built to absorb.
How much does a reserve study cost for a condo or HOA?
Standard reserve studies commonly cost $3,000 to $15,000 or more depending on size and complexity, with a Florida SIRS (which requires a licensed engineer or architect) typically running toward the higher end because of the structural inspection scope required by statute.
Are HOA special assessments tax deductible?
Generally no, for a personal residence, because the IRS treats these like non-deductible personal or home improvement costs. For rental property, assessments for repairs are usually deductible as a rental expense, while capital improvement assessments typically get added to the property's cost basis instead. Confirm with a CPA.
What's the difference between a SIRS and a regular reserve study?
A SIRS is a Florida-specific structural reserve study, required for condos and co-ops 3 stories and up, prepared only by a licensed engineer or architect, covering structural and life-safety components. A regular reserve study covers broader items like roofing and paving and can be prepared by a reserve specialist.
Can a Florida condo association still waive reserve funding?
Not for SIRS structural components. As of December 31, 2024, associations subject to SIRS can no longer vote to waive or reduce reserve funding for structural items identified in the study. Reserve waivers may still be possible for non-SIRS components, subject to the association's declaration and current statute.
Who can legally perform a Florida SIRS?
Florida law requires a SIRS to be performed by a licensed engineer or architect, not a general reserve preparer or community association manager. Boards should verify current Florida licensure through the state's license verification system before hiring anyone for this work.
Does Chapter 720 require HOAs to do a reserve study?
No. Chapter 720, which governs Florida homeowners associations, does not include a statutory mandate for reserve studies or structural inspections comparable to the condo requirements in Chapter 718. Any requirement typically comes from the HOA's own declaration, bylaws, or lender requirements, not state law.
What components must a Florida condo reserve study include at minimum?
Under section 718.112, budgets must include reserves for roof, building painting, pavement resurfacing, and any item with a deferred maintenance or replacement cost over $10,000, plus, for SIRS-covered buildings, all structural components the SIRS identifies, such as load-bearing walls, waterproofing, and the primary structural members.
