Special assessments in condos: what Florida boards must know

Last updated 2026-07-24

What is a special assessment in a condo association?

A special assessment is money a condo association charges owners outside the normal monthly or quarterly dues, to pay for something the regular budget and reserves don't cover. It's different from your regular assessment (the recurring fee that funds operations and reserve contributions). A special assessment is a one-time (or sometimes installment) charge tied to a specific need: a new roof, elevator replacement, storm damage repair, or the concrete restoration work a Milestone Inspection or SIRS report turns up. Florida Statutes chapter 718 governs how condo associations operate, including assessment authority. Section 718.116 makes clear that assessments, however levied, become the owner's personal debt to the association, enforceable through the association's lien rights. The board's authority to levy a special assessment generally comes from the declaration and bylaws, more than the statute, so the exact process (board vote only, or membership vote required above a dollar threshold) depends on your documents. Boards should confirm the specific approval process with association counsel, because declarations vary a lot on this point. What's changed the calculus for a lot of Florida buildings since 2022 is SB 4-D and its follow-up legislation. Buildings three stories or taller now face structural integrity reserve study (SIRS) requirements and Milestone Inspection deadlines tied to age and coastal proximity. When those inspections find deferred maintenance, boards that don't already have the reserve money often have exactly one option left: a special assessment. For background on how those structural deadlines work, see milestone inspections and reserve study.

What are HOA assessments, and how do they differ from condo assessments?

HOA assessments are the fees a homeowners' association charges to fund shared operations and reserves, same basic concept as condo assessments but governed by a different statute. Florida HOAs (mostly single-family and townhome communities with shared common areas) fall under Florida Statutes chapter 720, not chapter 718. Condos fall under chapter 718. The terminology ("regular assessment" vs "special assessment") is the same in both worlds, but the notice requirements, reserve funding rules, and the 2022-2023 structural reforms differ. The SIRS and Milestone Inspection mandates that reshaped condo reserve planning apply to condominiums and, as of recent amendments, to some cooperative associations. They generally do not apply the same way to typical single-family HOAs, which is a distinction a lot of board members get wrong when they compare notes with a friend on an HOA board. If your community is a true HOA rather than a condominium, see HOA special assessment and HOA reserve study for the chapter 720 specific rules, which this article doesn't cover in depth.

What is a reserve study, and what is it for in an HOA or condo?

A reserve study is a professional assessment of a building's major common-area components (roof, plumbing, structure, paint, pavement, elevators, and more), how much life each has left, and how much money the association needs to save now so it can pay for replacement later without a shock bill to owners. A qualified reserve study firm or engineer inspects the property, estimates remaining useful life for each component, and builds a funding schedule. For condos, Florida's version is more specific: the Structural Integrity Reserve Study (SIRS), required under section 718.112, F.S., for condominium buildings three stories or more in height. A SIRS must be performed by a licensed engineer or architect and must address specific structural components: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing, electrical systems, plumbing, waterproofing, exterior painting, and windows, among others listed in the statute. The Florida Legislature's own text of section 718.112(2)(g) lays out these components and requires that the SIRS be updated at least every 10 years. A reserve study for an HOA (chapter 720) is similar in method but not mandated the same way statewide; some HOAs choose to do one voluntarily because it's good financial practice, others are required by local ordinance or lender requirements. The point of any reserve study, condo or HOA, is the same: turn guesswork about "we'll figure it out when the roof leaks" into an actual number, so the board isn't blindsided. See reserve study for condo association for a component-by-component breakdown.

How much does a reserve study or SIRS cost?

Costs vary a lot by building size, age, and how many components need engineering-level inspection, but published ranges give a working sense of the number. Community association management and reserve industry sources commonly cite roughly $3 to $5 per unit for basic reserve study updates in smaller communities, while a full-scope SIRS engineering inspection for a mid-size condominium (50 to 150 units) often runs from around $5,000 to $15,000 or more, and can run higher for large or structurally complex buildings, waterfront high-rises, or properties needing invasive testing (core samples, concrete probes). There's no single statewide fee schedule and DBPR doesn't publish a price list, so boards should get at least two or three quotes from licensed engineers or reserve specialists before assuming a number. A cheap SIRS from an unqualified provider is a false economy: the statute requires the study be done by a licensed engineer or architect (section 718.112(2)(g), F.S.), and a study that misses a structural issue can cost the association far more later, in emergency repair costs and liability exposure. Budget for the study itself as a line item separate from the reserve contributions it recommends. Some boards try to fold the SIRS cost into general operating funds; others treat it as a small special assessment of its own if reserves are thin. Either way, get it scheduled early. Engineers doing SIRS work statewide have been backed up in peak buildings-turning-30 years, and waiting until the deadline month is a bad plan.

How much should a condo or HOA have in reserves?

90-100% fully funded	Low risk of near-term special assessment
70-89% funded	Moderate risk; monitor closely
30-69% funded	Elevated risk; plan for possible assessment
Under 30% funded	High risk; special assessment likely if a major system fails	This table reflects general reserve-funding risk categories used in reserve study practice, not a specific Florida statutory threshold; actual risk depends on component age and condition. For state-specific relief programs some associations have used to phase in these obligations, see Florida condo reserve fund relief.

There's no flat percentage that fits every building; the right reserve number is whatever your reserve study or SIRS says you need to fully fund replacement of each major component on schedule. That said, the industry rule of thumb many reserve specialists use as a sanity check is that reserves should be funded at 70% or more of the "fully funded" ideal to avoid a high near-term risk of special assessments, based on reserve funding models used across the Community Associations Institute's published reserve guidance. Below roughly 30% funded, associations are considered "poorly funded" and at elevated risk of a large special assessment hitting owners with little warning. For Florida condos specifically, the rules got sharper after the Surfside collapse in 2021. Section 718.112(2)(f), F.S. now requires that reserves for the SIRS-covered components (roof, structure, plumbing, and the rest of the statutory list) be funded based on the actual reserve study, not the old member-vote option to waive or reduce them. Associations can no longer vote to waive SIRS-component reserves or use them for anything other than their designated purpose, starting with the reserve study performed on or after December 31, 2024, for most associations under the phase-in schedule; confirm the exact date and phase-in status with your association's counsel because the statute has been amended more than once since 2022. | Reserve funding level | General risk profile |

What triggers a special assessment after a Milestone Inspection or SIRS?

A special assessment usually gets triggered when an inspection finds work that costs more than what's sitting in reserves, and the timeline for the repair (often driven by a Milestone Inspection Phase 2 report or a life-safety finding) doesn't allow years of gradual saving. Florida's Milestone Inspection program, under section 553.899, F.S., requires buildings three stories or higher to get a structural inspection at 30 years from certificate of occupancy (25 years if within three miles of the coast), and every 10 years after that. If a Phase 1 inspection finds "substantial structural deterioration," a Phase 2 inspection follows, and that report often becomes the basis for a scope-of-work estimate the board has to fund. The most common triggers in practice: concrete spalling and rebar corrosion found during Milestone or SIRS inspections, roof replacement after storm damage exceeds insurance proceeds, elevator modernization required by code, and plumbing or electrical systems reaching end of life across an entire building at once (a common problem in buildings built in a single phase in the 1970s-1990s). None of these show up overnight; they show up in inspection reports the board may have been sitting on for months. Boards facing this situation should get the engineer's scope of work and cost estimate in writing, get at least one independent second opinion on major cost items, and calculate whether the special assessment can be spread over installments (many declarations and Florida practice allow this) rather than a lump-sum due in 30 or 60 days, which can force unit sales or hardship for owners on fixed incomes.

What notice and voting rules apply to a condo special assessment?

Florida law requires specific advance notice for board meetings where a special assessment will be discussed, and the notice period is longer when the assessment relates to the SIRS-covered structural components. Under section 718.112(2)(c)2, F.S., notice of a board meeting where a special assessment for SIRS-related deficiencies will be considered must be mailed, delivered, or electronically transmitted to unit owners, and posted conspicuously on the property, not less than 14 days before the meeting. The statute states that notice "must specifically state that assessments will be considered and provide the estimated cost and description of the proposed project" for these structural-related special assessments. For special assessments not tied to SIRS components, the general notice rule under section 718.112(2)(c)1 still applies: notice of any meeting where a special assessment will be considered must be provided at least 14 days in advance, with a statement that assessments will be discussed. Whether the assessment needs a full membership vote, a board vote only, or both, depends on the declaration and bylaws' specific thresholds, which is exactly the kind of governing-document question a board should route to its own counsel rather than guess at. Getting notice wrong isn't a small clerical error. An improperly noticed special assessment vote can be challenged and invalidated, which means starting the whole process over while the underlying repair problem (a leaking roof, a failing seawall) gets worse. Boards juggling a Milestone deadline, a SIRS update, and a special assessment vote all at once benefit from a single tracked calendar rather than three separate mental to-do lists; that's the specific gap a $199 Board Compliance Kit is built to close, by organizing the deadlines, notice templates, and document checklist in one place. It doesn't replace the engineer, the reserve study firm, or your attorney; it keeps their deadlines from falling through the cracks.

Are condo or HOA special assessments tax deductible?

For most individual condo owners, special assessments are not tax deductible, because the IRS treats them as capital improvements to your property rather than a deductible expense, similar to how you can't deduct the cost of a new roof on your personal home. The IRS's general guidance on rental and personal-use property (see IRS Publication 527 for rental property and Publication 530 for homeowners) draws this same line: routine maintenance and operating costs may be deductible in specific contexts (like a rental unit), but capital improvements get added to your cost basis instead, which reduces capital gains tax when you eventually sell rather than giving you a deduction now. There are two narrow exceptions worth knowing. First, if the unit is a rental property, a special assessment for a capital improvement typically gets depreciated over time as part of the property's basis rather than deducted immediately, though a portion allocated to repairs (versus improvements) may be currently deductible; this is a facts-and-circumstances call best made with a CPA. Second, if a special assessment is specifically for casualty-loss repair after a federally declared disaster and the owner has an uninsured loss, there may be a casualty loss deduction angle under IRC rules, but the rules are narrow post-2017 tax law changes and don't apply to most routine special assessments. No Florida statute or IRS publication says "condo special assessments are deductible" in the way homeowners sometimes hope. Don't rely on this article for a tax filing decision. Talk to a CPA who can look at whether your unit is a primary residence, second home, or rental, because that changes the answer.

How can a board avoid or reduce future special assessments?

The single biggest lever is funding reserves at or near 100% of what the reserve study or SIRS recommends, every year, without deferring or borrowing from one component's reserve to cover another. Boards that treat reserve contributions as optional (raising dues feels bad, so let's skip this year) are the ones that end up needing a $15,000 per-unit special assessment five years later when the roof actually fails. A few concrete practices help: - Update the reserve study or SIRS on the statutory schedule (at least every 10 years for SIRS under section 718.112(2)(g), F.S.), and don't wait until it's overdue to start scheduling the engineer.

• Get multiple contractor bids before finalizing a special assessment amount; boards sometimes assess based on a single rough estimate and end up over- or under-collecting.
• Consider installment payment plans for large assessments; a lump sum due in 30 days can force distressed sales, which hurts property values for everyone in the building.
• Look at condo special assessment insurance products, which some associations use to help owners finance their share, though these aren't a substitute for adequate reserves.
• Keep a written, dated record of every notice, vote, and inspection report; if a special assessment is ever challenged, the board's paper trail is the first thing counsel will ask for. None of this is exciting work. It's spreadsheets, calendar reminders, and saying no to deferring a contribution one more year. But boards that do it consistently are the ones that never have to send an owner a five-figure bill with 30 days to pay.

Frequently asked questions

What is a reserve study?

A reserve study is a professional evaluation of a building's major shared components (roof, plumbing, structure, paving, and similar systems), their remaining useful life, and the savings schedule needed to replace them without a surprise special assessment. In Florida condos three stories and up, the structural version is called a SIRS and is required under section 718.112, F.S.

What is a reserve study for an HOA?

For an HOA (chapter 720 in Florida), a reserve study serves the same purpose as for a condo: it inspects common-area assets, estimates when each will need replacement, and calculates how much the association should save annually. HOAs aren't subject to Florida's condo-specific SIRS mandate, but many do voluntary reserve studies as sound financial practice.

What is an HOA assessment?

An HOA assessment is money the homeowners' association charges owners to cover shared costs: regular assessments fund ongoing operations and reserves, while special assessments cover one-time needs the budget doesn't already have money for, like storm repairs or a major system replacement.

How much should an HOA have in reserves?

There's no single required percentage, but reserve specialists generally consider 70% or more of the "fully funded" reserve study target a reasonably safe zone, while funding under 30% carries high risk of a large special assessment. The right number for your association comes from its own reserve study, not a generic rule.

How much does a reserve study cost for a condo association?

Costs vary by building size and scope, but reserve study updates for smaller communities often run in the range of a few dollars per unit, while a full SIRS engineering inspection for a mid-size Florida condominium commonly runs from about $5,000 to $15,000 or more, higher for large or structurally complex buildings.

Are condo special assessments tax deductible?

Generally no. The IRS treats special assessments for capital improvements as additions to your property's cost basis rather than a deductible expense, similar to a new roof on a personal residence. Rental property owners may get different treatment through depreciation; check with a CPA for your specific situation.

How much notice does a Florida condo board have to give before a special assessment vote?

For special assessments tied to SIRS structural components, Florida law (section 718.112(2)(c)2, F.S.) requires at least 14 days' notice, mailed or delivered to owners and posted on the property, stating the estimated cost and project description. General special assessment notices also require at least 14 days under section 718.112(2)(c)1, F.S.

Can a Florida condo association still waive SIRS reserve funding?

No, not for the structural components covered by the SIRS after the statutory phase-in took effect. Section 718.112(2)(f), F.S. removed the prior option to waive or reduce reserves for SIRS-covered items by member vote; confirm your association's specific compliance date and status with counsel since this has changed more than once since 2022.

What's the difference between a regular assessment and a special assessment?

A regular assessment is the recurring dues charge (monthly or quarterly) that funds normal operations and planned reserve contributions. A special assessment is a separate, usually one-time or installment charge levied when an unexpected or underfunded cost, like a major repair, exceeds what the regular budget and reserves can cover.

Can owners refuse to pay a condo special assessment?

No, not legally. Once a special assessment is properly levied under the declaration and Florida Statutes chapter 718, it becomes each owner's personal debt to the association, enforceable through the association's lien and foreclosure rights under section 718.116, F.S., the same as unpaid regular assessments.

Does a Milestone Inspection always lead to a special assessment?

Not always. If reserves are well funded relative to what the Milestone Inspection or follow-up SIRS finds, the association may be able to pay for repairs without a special assessment. It becomes necessary when reserve balances and the annual budget can't cover the engineer-estimated repair cost on the required timeline.

What is a SIRS, and how is it different from a regular reserve study?

A SIRS (Structural Integrity Reserve Study) is Florida's mandatory, engineer-performed reserve study for condo buildings three stories or higher, covering a specific statutory list of structural components under section 718.112(2)(g), F.S. A general reserve study can cover more components (paint, landscaping, amenities) but isn't legally required in the same way for most associations.
