TL;DR
An HOA assessment is money owners are legally obligated to pay their association, either as regular dues covering routine operating costs or a special assessment covering an unbudgeted or large expense (a roof, a pipe repair, a lawsuit judgment). Florida condo law (Ch. 718) also requires funded reserves for structural components, backed by a reserve study.
What is an HOA assessment?
An HOA assessment is a mandatory charge your association levies against your unit or lot under authority granted in the recorded governing documents (the declaration, articles, and bylaws). It is not optional and it is not a fee for a service you can decline. If you own in the community, you owe it, the same way you owe property tax on the parcel. Most people use "HOA assessment" and "HOA dues" interchangeably for the regular monthly or quarterly charge. Technically, "assessment" is the broader legal term. Your regular dues are one kind of assessment (a "regular assessment"). A one-time or short-term extra charge for something the regular budget didn't cover is a "special assessment." Both come from the same legal power: the association's right, under its declaration and Florida law, to assess owners for common expenses. In Florida, condominium associations operate under Chapter 718, Florida Statutes, which defines "assessment" as "a share of the funds required for the payment of common expenses, which from time to time is assessed against the unit owner." [1] HOAs (non-condo, typically single-family or townhome communities) fall under Chapter 720 instead, with similar mechanics but a separate statute. If your community is a condo, Chapter 718 governs; if it's a homeowners' association on platted lots, Chapter 720 applies. Confirm which one covers your community with your association's counsel, because the reserve and disclosure rules differ. The practical point for a board member: an assessment isn't a fundraiser. It's a legal mechanism, tied to your governing documents, that creates a debt owed by each owner, and unpaid assessments typically become a lien on the unit under state law.
What are HOA assessments used for?
Regular assessments fund the operating budget: landscaping, insurance premiums, management fees, utilities for common areas, pool maintenance, and contributions to reserves. This is the predictable, budgeted number owners pay every month or quarter. Special assessments cover things the operating budget wasn't built to absorb: a roof replacement that came due early, storm damage not fully covered by insurance, a legal settlement, or (increasingly common in Florida) the funding gap left when a building's reserves were underfunded or waived for years and a milestone inspection or structural reserve study turns up deferred repairs. Reserve assessments (or reserve contributions) are the slice of your regular assessment set aside specifically for future capital repairs and replacements, rather than day-to-day operating costs. In Florida condos, this bucket is no longer optional for structural items after the reforms following the 2021 Surfside collapse. As of the amendments to Chapter 718, associations must fund reserves for items covered by a Structural Integrity Reserve Study (SIRS), and boards can no longer vote to waive or reduce those specific reserves. [2] See our reserve study guide for how that requirement actually works building by building.
What is a reserve study?
A reserve study is a professional, physical and financial assessment of an association's major common-area components (roofs, pavement, painting, pool, elevators, and for condos, structural items like load-bearing walls, waterproofing, and building systems), estimating each component's remaining useful life and the future cost to repair or replace it. The output is a funding schedule showing how much the association should be setting aside now to avoid a large special assessment later. A reserve study for an HOA generally has two halves: a physical analysis (site visits, component inventories, condition assessments) and a financial analysis (current reserve balance, funding plan, contribution schedule). Most studies are updated every three to five years, with a visual update in between, because material costs and component conditions change. For Florida condominiums specifically, the Structural Integrity Reserve Study (SIRS) is a distinct, statutorily defined version. Under Section 718.112(2)(g), a SIRS must be performed by a licensed engineer or architect, and it must cover specific structural components: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing/fire protection systems, plumbing, electrical, and waterproofing/exterior painting, among others listed in the statute. [2] A general, non-structural reserve study (covering things like pool resurfacing or clubhouse carpet) doesn't satisfy the SIRS requirement on its own. Our hoa reserve study and reserve study for condo association pages break down which version applies to your building type and size.
What is a reserve study for an HOA (vs. a condo SIRS)?
A standard HOA reserve study, used by homeowners' associations under Chapter 720 and by condos for non-structural components, is a financial planning tool. It's smart practice, and many mortgage and insurance underwriters expect to see one, but Chapter 720 does not impose the same mandatory structural study or funding lock that Chapter 718 now imposes on condos three stories and taller. A SIRS is narrower and mandatory. It only applies to condominium buildings that are three stories or more in height (with some exceptions for certain single-family, two-family, and three-family structures), and it must be completed by December 31, 2024, for buildings reaching their milestone inspection threshold, per Section 718.112(2)(g). [2] The person doing the SIRS must be a licensed engineer or architect, not a reserve-study consultant without that license, for the structural components it covers. The short version: every board benefits from a general reserve study. Florida condo boards in buildings 3+ stories are legally required to get a SIRS, and once they have one, the reserve line items it identifies must be funded at 100 percent of the study's recommendation, no owner vote to waive allowed, starting with the fiscal year beginning January 1, 2025 (following legislative extensions in 2023 and 2024). [2] [3] Confirm your building's exact deadline and applicability with your association's counsel and your county building department, since local interpretation of height and story counts can vary.
How much should an HOA have in reserves?
There's no single dollar figure or percentage that's "correct" for every association, because the right reserve balance depends entirely on your building's age, components, and replacement costs. What reserve specialists look at instead is "percent funded": your current reserve balance divided by the theoretical full funding level for all components at their current age. A 100 percent funded reserve means you have exactly what you'd need if every component failed on schedule tomorrow. Industry guidance from reserve-study professionals generally treats anything above 70 percent funded as reasonably healthy, and anything under 30 percent as a red flag for special assessment risk, though these aren't statutory thresholds in Florida, just common industry benchmarks used by firms like the Community Associations Institute and CAI-affiliated reserve specialists. Florida law does not mandate a specific percent-funded target for HOAs under Chapter 720. For condos, the newer statute doesn't set a percent-funded target either; it requires that reserves for SIRS-covered components be funded based on the study's straight-line or component-based schedule, without the old option to fund below that level by owner vote. [2] The honest answer for a board asking "how much should we have in reserves" is: get a current reserve study, look at the funding schedule it recommends for your specific roof age, pipe age, and paint cycle, and fund to that number. Guessing a round number like "$500,000" without a study behind it is how boards end up blindsided.
How much does a reserve study cost?
Costs vary widely by community size, number of components, and whether it's a full study (with site visit) or an update. For a typical HOA or condo association, a full reserve study commonly runs somewhere in the low thousands to around $10,000-$15,000 for larger or more complex properties, with smaller communities sometimes paying less and very large or high-rise buildings paying more. There is no single federal or Florida state fee schedule for this service; pricing is set by private reserve-study firms and licensed engineers, so get multiple quotes. A Florida condo SIRS, because it must be performed or supervised by a licensed engineer or architect and covers structural components across the whole building envelope, generally costs more than a routine HOA reserve study covering pools and parking lots. Costs scale heavily with square footage, number of stories, and accessibility of structural elements (a beachfront tower with wrapped balconies costs more to inspect than a low-rise garden condo). Get quotes from at least two or three licensed firms, and ask each what specifically is included, since a bare-bones SIRS and a full reserve study with financial planning are priced differently. Budget for repeat costs too. Reserve studies aren't a one-time expense: a full update every 3-5 years, with lighter interim updates, is standard practice, and Florida's SIRS requirement effectively locks condos into recurring engineering assessments going forward. [2]
Are HOA special assessments tax deductible?
Generally, no, not for the individual owner of a personal residence. Regular HOA dues and special assessments are typically treated by the IRS as a personal, nondeductible expense, similar to a repair on your own home, because you're paying to maintain your own property's value and common areas you use personally. [4] There are narrow exceptions. If you rent out the unit as a rental property, HOA assessments (including special assessments for repairs) are generally deductible as a rental expense on Schedule E, the same way any rental operating cost would be. [4] If part of your home is used for a qualifying home office, a portion of the assessment tied to that business-use percentage might be deductible. And if a special assessment is specifically for a capital improvement (rather than a repair) on a rental or business property, it may need to be capitalized and depreciated rather than deducted immediately, per general IRS capital improvement rules. This isn't tax advice, and every situation is different depending on how the assessment is characterized and how the property is used. Talk to a CPA before assuming a special assessment is deductible, and keep the association's notice letter and invoice, since you'll need to show what the assessment was actually for.
How does a special assessment actually get approved?
The process is set by your declaration and bylaws, not by a universal statute, so the exact steps (board vote only, or board vote plus a membership vote above a certain dollar threshold) depend on your specific documents. Generally, the board has authority to levy assessments needed to meet its budgeted obligations, but many governing documents require a membership vote for assessments above a set percentage of the annual budget or for non-budgeted capital items. For Florida condos, Section 718.116 governs assessment liability and lien rights, establishing that assessments not paid when due bear interest and can result in a lien against the unit. [5] The board typically must give owners written notice of a special assessment, including its purpose and the payment schedule, before it takes effect; the specific notice period and required content again trace back to your declaration and any applicable statute section, so this is a genuine legal-interpretation question for your association's counsel, not something a general article can answer for your building. Our hoa special assessment explainer walks through notice timelines, payment plan options, and what happens if an owner simply can't pay, in more depth than fits here.
How is a milestone inspection related to reserves and assessments?
A milestone inspection is the separate, structural-safety inspection Florida now requires for condo and cooperative buildings three stories or taller, generally at 30 years after the certificate of occupancy (25 years if within three miles of the coast), and every 10 years after that, under Section 553.899, Florida Statutes. [6] It's a life-safety inspection, not a financial planning document, but the two are closely linked in practice. When a milestone inspection turns up "substantial structural deterioration," the association often has to move fast on repairs, and if reserves weren't funded for that scope, a special assessment follows almost immediately. This is exactly the sequence that happened at multiple Florida buildings after 2022: milestone inspection finds deferred structural issues, reserves aren't there because they were waived for years, board levies a large special assessment on short notice. The SIRS requirement exists specifically to break that cycle by forcing reserve funding ahead of the deterioration, not after it's found. [2] [2] If your building is approaching its 25- or 30-year window, the milestone inspection and the SIRS are two separate deliverables from two separate (though sometimes overlapping) licensed professionals, and your board needs to track both deadlines independently, not assume one covers the other.
What happens if an HOA doesn't have enough reserves?
If reserves fall short of what a needed repair actually costs, the board has limited options: levy a special assessment, take out a loan (if the declaration and lender allow it), delay the repair (risky for structural items, and increasingly restricted by Florida's post-Surfside statutory changes), or some combination of all three. For Florida condo buildings now subject to SIRS funding requirements, the option to simply vote to waive or reduce structural reserves is gone starting with fiscal years beginning on or after January 1, 2025 (per the legislative changes enacted in 2022 and adjusted in 2023 and 2024). [2] [3] That means boards that used to defer painful reserve contributions by member vote no longer have that release valve for SIRS-covered items, which is exactly why more Florida condos are seeing large special assessments right now: years of underfunding are colliding with a hard funding mandate and, in many buildings, an overdue milestone inspection at the same time. Owners considering a purchase in an older Florida condo should ask to see the association's most recent reserve study or SIRS, its milestone inspection status, and its current percent-funded number before closing. A building with a healthy, current reserve study and a completed milestone inspection is a materially different financial risk than one that's behind on both.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment of an association's major shared components (roofs, paving, pools, and for condos, structural elements), estimating remaining useful life and future replacement costs, then producing a funding schedule showing how much the association needs to save now to avoid future special assessments.
What is an HOA assessment?
An HOA assessment is a mandatory charge the association levies against owners under authority in the recorded governing documents, covering shared operating costs and reserve contributions. It includes both regular (recurring) assessments and special (one-time, unbudgeted) assessments, and unpaid assessments typically become a lien on the property.
How much should an HOA have in reserves?
There's no universal dollar amount; the right figure comes from a current reserve study specific to your components and their ages. Industry practice generally treats above 70 percent funded (of the theoretical full funding level) as healthy and below 30 percent as high risk, though Florida law sets no specific percent-funded target for HOAs.
What are HOA assessments used for?
Regular assessments fund routine operating costs like landscaping, insurance, and management fees, plus reserve contributions. Special assessments fund unbudgeted or large capital expenses, such as a roof replacement, storm damage, a legal judgment, or repairs identified by a milestone inspection or SIRS that reserves weren't built to cover.
How much does a reserve study cost?
Costs vary by size and complexity, commonly ranging from a few thousand dollars for a smaller community to $10,000-$15,000 or more for larger or high-rise buildings needing a licensed engineer's structural review (SIRS). There's no set state fee; get quotes from multiple licensed firms, since scope varies significantly between providers.
Are HOA special assessments tax deductible?
Generally no, for a personal residence; the IRS treats them like a nondeductible personal home expense. Exceptions exist for rental properties (deductible as a rental expense on Schedule E) and qualifying home-office use. Capital-improvement assessments on rental property may need to be depreciated rather than deducted outright. Confirm with a CPA.
What is the difference between a regular assessment and a special assessment?
A regular assessment is the recurring monthly or quarterly charge covering the budgeted operating expenses and planned reserve contributions. A special assessment is an additional, usually one-time charge for expenses the regular budget didn't cover, like an emergency repair, insurance shortfall, or a structural fix identified after a SIRS or milestone inspection.
What is a SIRS and how is it different from a regular reserve study?
A Structural Integrity Reserve Study (SIRS) is a Florida-specific, statutorily required study for condo buildings three stories or taller, performed by a licensed engineer or architect, covering structural components listed in Section 718.112(2)(g), Florida Statutes. A general reserve study covers non-structural items like pools and landscaping and isn't a substitute for a SIRS.
Can a condo board waive reserve funding in Florida?
No, not for SIRS-covered structural components, starting with fiscal years beginning on or after January 1, 2025. Prior law let owners vote to waive or reduce reserves; the post-Surfside amendments to Chapter 718 removed that option specifically for structural reserve items identified in a completed SIRS.
How often does an association need to update its reserve study?
Common industry practice is a full reserve study every 3-5 years with lighter visual updates in between, since costs and component conditions change over time. Florida's SIRS requirement effectively creates recurring engineering assessments for condo buildings going forward, though the exact statutory recurrence interval should be confirmed with your association's counsel.
What happens if I don't pay an HOA or condo assessment?
Unpaid assessments typically accrue interest and can result in a lien against your unit under Florida law (Section 718.116 for condos), potentially leading to foreclosure in serious, prolonged cases. Payment plan options and notice requirements depend on your governing documents, so contact the association promptly if you're struggling to pay.
Does every condo building in Florida need a SIRS?
Only condo buildings three stories or more in height generally need a SIRS, with some exceptions in the statute for certain smaller residential structures. Confirm your building's specific applicability and deadline with a licensed engineer and your association's counsel, since story-count and structural definitions can get technical.
