TL;DR
Florida does not require most HOAs to get a professional reserve study. That mandate (via SIRS) applies to condo associations 3+ stories under Fla. Stat. 718.112. HOAs set reserves through their own budget process unless their governing documents say otherwise. Most planners still recommend one every 3-5 years; costs typically run $3,000 to $20,000+ depending on building size and site complexity.
What is a reserve study?
A reserve study is a physical inspection and financial forecast of a community's shared property, done by a qualified engineer, reserve specialist, or firm that combines both. The person doing the work walks the property, catalogs major common-area components (roofs, pavement, pools, elevators, painting, roads, seawalls, clubhouses), estimates each item's remaining useful life, and then builds a multi-year funding schedule showing how much money the association needs to set aside each year to pay for replacements without a surprise bill. A good study has two halves. The physical component inventory answers "what do we own, how old is it, and when will it fail." The financial analysis answers "given that timeline, how much do we need to save monthly, and how underfunded are we right now." Reputable studies (following methods from the Community Associations Institute and state-licensed reserve specialists) report a "percent funded" figure, comparing current reserve cash to the ideal reserve balance for where each component sits in its life cycle. [1] This is different from a milestone inspection or a Structural Integrity Reserve Study (SIRS), which are Florida-specific, statute-driven inspections tied to condo buildings 3 stories or taller. A generic "reserve study" is a financial planning tool any community association can commission voluntarily. A SIRS is a narrower, legally defined structural-component study that Florida condo associations meeting the height threshold must obtain under Fla. Stat. 718.112(2)(g). For more on how these differ, see our guide to SIRS-specific requirements and reserve studies for condo associations.
What is a reserve study for an HOA (versus a condo)?
For a homeowners' association (single-family homes, townhomes, or any community governed by Chapter 720 rather than Chapter 718), a reserve study serves the same financial purpose but carries much less legal weight in Florida. Chapter 720 requires HOAs to include reserve line items in the proposed annual budget if the association is funding reserves, and members can vote to waive or reduce reserve funding each year at a duly noticed meeting. [2] But Chapter 720 does not require HOAs to commission a professional, engineer-led reserve study the way Chapter 718 now requires condos to get a SIRS. That gap matters practically. A condo board in a 3-story-plus building has a hard statutory deadline for its first SIRS (originally December 31, 2024, though the legislature has adjusted timing for some associations through subsequent bills, so confirm current deadlines with counsel). An HOA board has no equivalent state mandate forcing it to hire an inspector. The board (or the declaration) decides whether to get one, how often, and how detailed it should be. That said, plenty of HOAs choose to commission reserve studies anyway, especially larger, amenity-heavy communities with pools, gated entries, private roads, or clubhouses. It is simply good governance, and it protects the board from claims that officers ignored a foreseeable, poorly funded future liability. Community Associations Institute's model reserve guidance recommends every association, HOA or condo, update its study every 3 to 5 years and review the numbers annually in between. [1]
What is an HOA assessment?
An HOA assessment is a fee the association charges each member (owner) to fund shared expenses. There are two main types. Regular assessments are the recurring dues, monthly or quarterly, that cover operating costs (landscaping, insurance, management fees, utilities for common areas) and reserve contributions. Special assessments are one-time or short-term charges the board levies outside the normal budget cycle, usually to cover an unexpected repair, a reserve shortfall, or a project the reserve fund cannot cover on its own. Under Florida's HOA statute, the board has authority to levy assessments as needed to meet the association's obligations, and the declaration or bylaws typically set the process and any notice or approval thresholds required for special assessments above a certain size. [2] Boards should check their own governing documents closely here, since Chapter 720 leaves a lot of the mechanics (caps, member votes, notice periods) to the declaration itself, and this article isn't offering legal interpretation of any specific association's documents; that's a job for association counsel. What are HOA assessments used for, practically? Roof and siding repairs, private road repaving, storm drainage fixes, gate and clubhouse maintenance, insurance premium spikes, and reserve fund top-offs after a shortfall is discovered are the most common triggers boards report.
How much should an HOA have in reserves?
There's no single dollar figure or statutory percentage that applies to every HOA in Florida, because Chapter 720 does not set a minimum reserve balance requirement for HOAs the way Chapter 718 increasingly does for condos. The honest answer is: enough to be at or near 100% funded relative to the components in your reserve study, which depends entirely on what your community owns and how old it is. Industry practitioners commonly talk in terms of "percent funded." A reserve fund that is 70% funded or higher is generally considered healthy by reserve specialists; funds below 30% funded are considered high-risk for special assessments or deferred maintenance. [1] These are industry rules of thumb from reserve-study professionals, not Florida statutory thresholds, so treat them as planning benchmarks rather than legal minimums. For condo associations specifically, Florida law is stricter and getting stricter. Since the SIRS requirement took effect, condo associations 3 stories or higher can no longer waive or underfund reserves for the specific structural components identified in a SIRS report; those reserve line items must be funded based on the SIRS professional's estimate, with limited exceptions. [3] HOAs still have more flexibility. Boards can and often do vote to reduce or waive reserve contributions annually, but doing so year after year is exactly how communities end up facing five- and six-figure special assessments when a roof or a road fails all at once.
How much does a reserve study cost in Florida?
Cost depends heavily on property size, number of components, and whether the study is a full study (with a site visit and detailed component inventory) or an update (using the prior study's data with a lighter site visit). Rough ranges reported by reserve-study firms and CAI-affiliated planners run from around $1,500 to $4,000 for a small HOA with few shared components, up to $10,000-$20,000+ for large condo towers with elevators, garages, pools, and extensive structural systems. [1] For Florida condo associations that also need a SIRS, costs run separately and are often higher because a licensed engineer or architect must physically inspect specific structural components (structure, roof, load-bearing walls, primary waterproofing, electrical, plumbing, pool decks if applicable, and flooring). [3] SIRS pricing generally scales with building height, unit count, and structural complexity, and boards report costs from several thousand dollars for smaller buildings into the tens of thousands for large, older high-rises. A cheaper "update" study, done every 2-3 years between full studies, typically costs less than half of a full study because the inspector isn't rebuilding the component inventory from scratch, just adjusting costs and remaining life estimates. Boards trying to control long-term costs often alternate: full study, then two update studies, then a new full study, repeating on a roughly 5- to 6-year full-study cycle.
Are HOA special assessments tax deductible?
For individual homeowners, no, in almost all cases. The IRS treats HOA assessments, including special assessments, as a nondeductible personal expense when the property is your primary residence, similar to how regular HOA dues are treated. [4] The IRS's own guidance on rental property expenses draws the distinction that matters here: HOA fees and assessments become deductible when the property is a rental or is used for business, because they're then an ordinary and necessary expense of producing rental income, and can be deducted as an operating expense (or, if the assessment is for a capital improvement, may need to be added to the property's basis and depreciated rather than deducted immediately). [5] So the honest, useful answer for a board member fielding this question from an owner: assessments on a primary residence are not deductible; assessments on a rental or investment property may be deductible as a business expense, and capital-improvement-related special assessments (a new roof, a major structural repair) usually get depreciated rather than deducted in one year. Owners should talk to their own tax preparer, since individual circumstances (home office use, mixed personal/rental use, timing of the assessment) change the analysis. Boards should never give members tax advice directly; refer them to a CPA.
How does Florida's SIRS requirement change what HOAs and condos need to do?
Florida's post-Surfside reforms created a hard split between condo associations and HOAs on this question, and it's easy for board members moving between the two governance types to get confused. Condo associations in buildings 3 stories or taller must obtain a Structural Integrity Reserve Study performed by a licensed engineer or architect, covering specific structural and life-safety components, and must fund reserves for those components based on the SIRS findings without the option to waive them by member vote. [3] This requirement sits inside Fla. Stat. 718.112, alongside the related milestone inspection requirement for older buildings near the coast under Fla. Stat. 553.899. HOAs governed by Chapter 720 are not swept into this SIRS mandate. Even a large, multi-building HOA with 3-story townhome buildings does not need a SIRS unless the community is legally structured as a condominium association under Chapter 718. Boards sometimes assume height alone triggers the requirement; it doesn't. Legal structure (condo versus HOA) is what matters, and that's a documents-and-formation question worth confirming with association counsel if there's any ambiguity about how the community is organized. What HOAs do still need to watch is their own declaration. Some older HOA declarations, particularly ones drafted or amended after 2008 legislative reserve-funding reforms, incorporate reserve-funding language voluntarily, effectively opting into stricter internal rules than Chapter 720 requires. Boards should read their own declaration and bylaws (or have counsel read them) before assuming state law sets the floor; the declaration might set a higher one. Our HOA reserve study guide covers this distinction in more detail.
What triggers a special assessment, and how can boards avoid one?
Special assessments almost always trace back to one of two failures: an unexpected repair nobody budgeted for, or a reserve fund that was underfunded on purpose (usually through repeated member votes to waive contributions) and finally ran out of runway. Roof failures, storm damage exceeding insurance payouts, structural repairs identified in a milestone inspection or SIRS, and major infrastructure failures (elevators, water intrusion, parking structures) are the most common triggers reported by Florida community managers. The practical fix is boring but effective: get a reserve study (or SIRS, if required), fund reserves to the level the study recommends, and resist the urge to vote reserves down every year just to keep monthly dues low. A board that consistently underfunds reserves is deferring a bill, not avoiding it, and the eventual special assessment is usually far larger and far less popular than the incremental dues increases would have been. Boards should also budget for the unglamorous parts: insurance deductibles have risen sharply across Florida in recent years, and a special assessment to cover a deductible after a storm is now common even for well-reserved associations. Building a small contingency line item into the operating budget, separate from long-term reserves, helps absorb these one-off costs without a full special assessment vote. See our guide on HOA special assessments and condo special assessment insurance options for more on managing this risk.
Who is qualified to perform a reserve study or SIRS in Florida?
For a SIRS, Florida law is specific: the inspection must be performed by a licensed engineer or architect. [3] DBPR licenses and regulates engineers and architects practicing in Florida, and boards can verify a professional's license status directly through the department's online license search. For a general (non-SIRS) reserve study, Florida doesn't mandate a specific license, but the market standard is to hire someone credentialed through a recognized reserve-study professional designation, often combined with, or reviewed by, a licensed engineer for the physical components. Boards should ask any reserve-study firm for references from other Florida associations, sample reports, and confirmation of relevant credentials before signing a contract. Boards should never accept a "reserve study" that is really just last year's numbers adjusted for inflation with no physical site visit. A real study, or a real update to one, involves someone walking the property. If a firm quotes an unusually low price with no site visit mentioned, ask directly what's included.
How can a board actually get organized around these deadlines?
Reserve planning, SIRS deadlines (for condos), and milestone inspection deadlines all involve different professionals, different statutes, and different clocks running at the same time, which is exactly how boards miss things. The practical fix most experienced board members land on is a single master calendar: one place tracking when the last reserve study happened, when the next one (or SIRS) is due, when milestone inspection reports are due, and when reserve-funding votes need to go back in front of members. Boards that don't want to build this tracking system from scratch, or that are managing a self-managed community without a professional management company, sometimes use a structured tool for this. BoardDeadline's $199 one-time Building-Specific Board Compliance Kit organizes your building's SIRS, milestone inspection, and reserve deadlines into one schedule with reminders, and helps the board communicate the timeline to owners. It doesn't replace the licensed engineer or reserve specialist the statute requires. Nobody can shortcut that part. It just keeps the paperwork and dates from slipping through the cracks between board meetings.
Frequently asked questions
What is a reserve study?
A reserve study is a professional inspection and financial forecast of a community's shared property (roofs, pools, roads, structural elements) that estimates each component's remaining life and builds a funding schedule showing how much the association should save each year. It combines a physical component inventory with a financial funding analysis, typically updated every 3 to 5 years.
What is a reserve study for an HOA?
For an HOA (Chapter 720 community), a reserve study works the same way as for a condo, estimating component life and recommending annual reserve contributions, but Florida doesn't legally require HOAs to obtain one. The board decides whether to commission a study, though many do so voluntarily for good financial planning and liability protection.
What is an HOA assessment?
An HOA assessment is a fee charged to each member to fund association expenses. Regular assessments cover recurring operating costs and reserves; special assessments are one-time or short-term charges levied outside the normal budget, usually for unexpected repairs or reserve shortfalls, subject to the process set out in the declaration and bylaws.
How much should an HOA have in reserves?
There's no Florida statutory minimum for HOAs. Reserve professionals commonly use "percent funded" as a benchmark: 70% funded or higher is considered healthy, below 30% is considered high-risk for special assessments. The right dollar amount depends entirely on your community's specific components and their age, which is why a reserve study matters.
How much does a reserve study cost?
Costs range roughly from $1,500-$4,000 for a small HOA with few shared components to $10,000-$20,000+ for large condo buildings with elevators, garages, and structural systems. Update studies (done between full studies) typically cost less than half of a full study since the inspector isn't rebuilding the component inventory from scratch.
Are HOA special assessments tax deductible?
For a primary residence, no; the IRS treats HOA assessments as a nondeductible personal expense. For rental or investment property, special assessments may be deductible as an operating expense, or added to the property's basis and depreciated if they fund a capital improvement. Owners should confirm treatment with their own CPA.
Does Florida law require HOAs to get a reserve study like condos do?
No. The SIRS (Structural Integrity Reserve Study) requirement under Fla. Stat. 718.112 applies specifically to condominium associations in buildings 3 stories or taller, governed by Chapter 718. HOAs governed by Chapter 720 have no equivalent statutory mandate, though some declarations voluntarily incorporate similar reserve-funding requirements.
What's the difference between a reserve study and a SIRS?
A reserve study is a voluntary financial planning tool covering any shared components an association owns. A SIRS is a Florida-specific, legally required study for qualifying condo buildings, limited to specific structural and life-safety components, performed by a licensed engineer or architect, with mandatory (non-waivable) reserve funding tied to the results.
Can an HOA board vote to waive reserve funding?
Under Chapter 720, HOA members can generally vote annually to waive or reduce reserve funding for the coming year, though the exact process is often set by the declaration and bylaws. This flexibility doesn't exist for condo SIRS-covered components, where reserve funding is mandatory once the SIRS identifies the components and costs.
Who can perform a reserve study or SIRS in Florida?
A SIRS must be performed by a licensed engineer or architect under Florida law. General reserve studies aren't statutorily restricted to a specific license, but the market standard is a credentialed reserve-study professional, often paired with an engineer's review of physical components. Boards can verify engineer or architect licenses through DBPR's online license search.
How often should a reserve study be updated?
Industry guidance from reserve-study professionals and Community Associations Institute generally recommends a full study every 3 to 5 years, with lighter update studies in between years to adjust cost estimates and remaining useful life figures without a full component re-inventory.
What happens if an HOA doesn't have enough in reserves?
When a major component fails and reserves fall short, the board typically has to levy a special assessment to cover the gap, since Chapter 720 gives boards authority to assess members as needed to meet association obligations. This is usually far more disruptive to owners than gradually funding reserves through regular dues would have been.
