TL;DR
A condo assessment is a fee owners pay for shared building expenses, either regular (budgeted, recurring) or special (unbudgeted, one-time). Florida law under Chapter 718 now requires fully funded reserves for buildings 3+ stories once a milestone inspection or SIRS is due, which is pushing many associations toward larger special assessments instead of gradual saving.
What is a condo assessment?
A condo assessment is money an owner owes the association, on top of any mortgage, to cover the building's shared costs. It's not optional and it's not a fee for extra services. It's how a condo association pays for insurance, landscaping, elevator maintenance, roof repairs, and increasingly, the reserve funding Florida now requires for structural components. Florida Statutes define an assessment broadly. Chapter 718.103 covers the terms used throughout the condo act, and 718.116 spells out when assessments become the owner's liability and what happens if they go unpaid, including the association's lien rights [1]. If you don't pay, the association can record a claim of lien against your unit and, eventually, foreclose on it, the same way a mortgage lender can. There are two kinds you'll deal with as a board member or owner: regular assessments and special assessments. Both are legally enforceable the same way. The difference is timing and purpose, not authority.
What are HOA assessments and how do they differ from condo assessments?
HOA assessments work almost identically to condo assessments in concept. They're recurring or one-time charges the association levies to cover shared costs, but the legal framework is different. Condominiums in Florida fall under Chapter 718. Homeowners associations (single-family and townhome communities with common areas, not unit-owned buildings) fall under Chapter 720. The SIRS and milestone inspection requirements that are driving huge special assessments right now (see below) apply specifically to condo and cooperative buildings three stories or more, under 718.112 and 553.899 [2][3]. A typical single-family HOA with no shared structural building generally isn't subject to those same reserve mandates, though its governing documents may still require reserves or allow special assessments for roads, pools, or clubhouses. If you're on an HOA board rather than a condo board, your assessment authority usually traces back to the declaration of covenants and Chapter 720.308, not 718.112. Read your documents. The word "assessment" gets used the same way, but the statutory guardrails differ.
Regular assessments vs. special assessments: what's the real difference?
| Frequency | Recurring (monthly/quarterly) | One-time or short series | |
|---|---|---|---|
| Set in | Annual budget | Board resolution, as needed | |
| Purpose | Operating costs + reserve funding | Unbudgeted repair, deficit, or reserve shortfall | |
| Owner notice | Annual budget meeting notice | Specific notice per bylaws/statute | |
| Predictability | High | Low, often sudden | Both are enforceable through the same lien and foreclosure mechanism under 718.116 [1]. The board doesn't need a unit-owner vote to levy a special assessment unless the declaration specifically requires one, though it does need to follow notice procedures in the bylaws and the statute. This surprises a lot of owners: the board can vote itself, at a properly noticed board meeting, to levy tens of thousands of dollars per unit. |
A regular assessment is the budgeted, recurring charge, usually monthly or quarterly, that funds the annual operating budget and reserve contributions the board adopted for the fiscal year. It's predictable. You can plan for it. A special assessment is an extra, usually one-time, charge levied when the regular assessment and existing reserves aren't enough to cover a cost. That could be a hurricane-damaged roof, a failed elevator, or the sudden, statute-driven need to fund structural reserves after a Milestone Inspection or SIRS report comes back showing deferred maintenance. | Feature | Regular assessment | Special assessment |
What is a reserve study, and what is it for?
A reserve study is a professional evaluation of a building's major shared components, roof, structure, plumbing, electrical, paving, painting, and so on, that estimates each component's remaining useful life and the cost to replace or restore it. The output is a funding schedule: how much the association should be setting aside now so the money is there when the component actually fails or wears out, instead of hitting owners with a surprise bill. For condo associations, reserve studies aren't just good practice anymore, they're partly mandated. Florida's Structural Integrity Reserve Study (SIRS) requirement, created after the 2021 Champlain Towers South collapse in Surfside, applies to condo buildings three stories or higher and requires a study of specific structural items: roof, load-bearing walls, primary structural members, floor, foundation, fireproofing, electrical systems, plumbing, waterproofing, and exterior painting, among others listed in 718.112(2)(g) [2]. A SIRS has to be performed, or at minimum the visual inspection portion has to be performed, by a licensed engineer or architect, per the statute's language on qualified persons. This isn't a job for a board member with a clipboard. The report has real legal weight: once an association turns over from developer control or reaches the size threshold, SIRS is due by December 31, 2024, for most existing associations, and every 10 years after that [2]. For an HOA (Chapter 720) without a multi-story residential building, a reserve study isn't mandated the same way, but it's still the only real tool for figuring out how much to save monthly instead of guessing. Read more in our reserve study guide and the HOA reserve study breakdown for the Chapter 720 side of this.
How much does a reserve study cost?
Costs vary a lot by building size, number of components studied, and whether it's a full study (with a site visit and physical inspection) or an update study (desktop review of a prior report). For a typical Florida condo association, expect somewhere in the range of $3,000 to $8,000 for a standard multi-component reserve study on a small to mid-size building, and $10,000 to $20,000 or more for a full SIRS-compliant structural study on a larger high-rise, especially one requiring destructive or invasive testing of concrete and rebar. There's no statewide fee schedule and no state agency publishes an official average, so treat these as market ranges gathered from what associations typically report paying licensed engineering firms, not a guaranteed quote. Get at least two or three bids from licensed engineers or reserve specialists before signing. A study that looks cheap upfront but misses required structural components under 718.112(2)(g) can force a costly redo. One cost-saving note: the statute allows a "visual inspection" SIRS in many cases rather than a full destructive-testing study, unless the building already has a Milestone Inspection report flagging substantial structural distress, which can push the cost and scope up significantly [2][3].
How much should an HOA or condo have in reserves?
There's no single dollar figure or percentage that Florida statute mandates as "the right reserve amount." The law instead requires that reserves be funded based on the actual, calculated cost of maintaining and eventually replacing each component identified in the reserve study or SIRS, not an arbitrary percentage of the budget. Under 718.112(2)(f), as amended after Surfside, condo associations subject to SIRS can no longer waive or reduce reserve funding for the structural items covered by the study. That waiver option, which many associations used for years to keep monthly fees artificially low, is gone for SIRS components effective with reserve fund years beginning after December 31, 2024 [2]. Non-SIRS reserve items (things like painting or paving that aren't structural) can still potentially be waived or underfunded if owners vote to do so, depending on the specific line item and current law, so confirm the current rule with your association's counsel since this area has changed more than once through legislative sessions. A rough industry rule of thumb some reserve professionals use is funding reserves to roughly 70% or more of the "fully funded" ideal (the theoretical amount if every component were funded exactly on schedule), but this is a professional guideline, not a statutory floor. The honest answer for "how much should we have" is: whatever your licensed reserve study says your specific components require, recalculated at least every few years as costs and component ages change. See our florida condo reserve fund relief piece for how some associations are handling the funding crunch.
Are HOA and condo special assessments tax deductible?
For most owners using a condo unit as a personal residence, no, a special assessment for repairs, capital improvements, or reserve funding generally isn't tax deductible in the way a mortgage interest payment is. The IRS treats these payments the way it treats any other cost of maintaining personal property: not deductible as an itemized expense. There are two situations where it gets more nuanced. If you own the unit as rental property, a special assessment used for repairs or capital improvements can typically be added to your cost basis (if it's a capital improvement, like a new roof) or, in narrower cases, deducted as a business expense in the year paid if it's for ordinary repair and maintenance on a rental unit. The IRS's guidance on rental property expenses is in Publication 527 [4]. The other case is casualty-loss-related assessments after a federally declared disaster, which can sometimes qualify for a casualty loss deduction, but the rules tightened significantly after 2017 (the Tax Cuts and Jobs Act limited casualty loss deductions mostly to federally declared disaster areas) [5]. This is genuinely a "talk to a CPA" area. Don't assume deductibility based on a neighbor's story; the treatment depends on how the assessment was used, your ownership type, and whether you itemize.
What triggers a special assessment for milestone inspections or SIRS?
A special assessment usually shows up after one of two structural reports flags a problem the association's reserves can't cover. The Milestone Inspection, required under 553.899 for condo and co-op buildings 3 stories or more, is due within 30 years of the building's certificate of occupancy (25 years if within 3 miles of the coast), and every 10 years after that [3]. If the inspecting engineer finds "substantial structural deterioration," a Phase 2 inspection and repair plan follows, often with a real dollar figure and a deadline attached. The SIRS process works in parallel: once the study identifies underfunded structural components, the association is legally barred from waiving that funding starting with reserve years after December 31, 2024 [2]. If reserves were underfunded for years (common in older buildings that kept dues low), the gap between what's owed and what's saved often has to be closed fast, and that means a special assessment, sometimes tens of thousands of dollars per unit. Boards facing this should get a bid from a licensed engineer for the repair scope, get a current reserve study, and then work out financing options (special assessment, reserve draw, association loan, or some blend) before setting a number. Our hoa special assessment and condo special assessment insurance guides walk through the financing and insurance angles in more detail.
How do boards actually calculate and levy a special assessment?
The board typically starts with a defined need: a repair estimate from a licensed contractor or engineer, or a funding gap identified in the reserve study or SIRS. From there, most declarations require the assessment to be allocated among units based on the same percentage ownership interest used for regular assessments, laid out in the condo's declaration. The board then has to hold a properly noticed board meeting (not necessarily an owner vote, unless the declaration says otherwise) and adopt a resolution setting the amount, the due date, and whether it's payable in a lump sum or installments. Florida law under 718.112 requires specific notice procedures for meetings where a special assessment is being considered, and owners are entitled to see the budget and supporting documentation. A practical note that catches a lot of first-term board members off guard: you can't just wire the estimate you get from one contractor straight into a per-unit number without checking the math against the declaration's allocation formula and confirming the notice requirements were followed exactly. Get this wrong and you risk a legal challenge that delays the whole repair. This is exactly the kind of process, not judgment call, that a structured compliance checklist helps with; our $199 Board Compliance Kit is built to organize the SIRS, milestone, and assessment notice timeline so boards don't miss a statutory step, though it doesn't replace your association's own counsel or the licensed engineer doing the actual inspection.
What happens if an owner can't pay a special assessment?
The association's remedies are the same as for any unpaid assessment. Under 718.116, unpaid assessments become a lien on the unit, the association can charge interest (statutory default rate or whatever the declaration sets) plus late fees, and after enough time, the association can foreclose the lien, similar to a mortgage foreclosure [1]. Some associations offer payment plans for large special assessments, especially SIRS-driven ones, because forcing dozens of owners into default at once isn't good for anyone, including the association's own cash flow and insurability. This isn't required by statute, it's a board policy decision, and boards should document it consistently so they're not accused of favoritism. Owners who genuinely can't pay should talk to the board and, separately, a real estate attorney early. Waiting until a lien is filed narrows the options considerably.
How can boards plan ahead instead of being blindsided by special assessments?
The single best defense against a shock special assessment is an accurate, current reserve study paired with a realistic, fully funded reserve line in the annual budget, done years before a Milestone Inspection or SIRS deadline forces the issue. Waiting until the inspection report lands to start thinking about money is how boards end up needing $40,000 per unit with 90 days notice. A few concrete habits help: get the reserve study updated every few years, not once and forgotten. Track your building's age against the 25-year (coastal) or 30-year (inland) Milestone Inspection deadline under 553.899 well in advance, not the year it's due [3]. Keep the reserve study, milestone inspection report, and SIRS report organized and easy to hand to a lender or buyer's attorney, because unresolved structural issues now show up in closing due diligence and can tank a sale. Boards juggling all of this on top of regular operations often lose track of which deadline applies to their specific building height and coastal distance. That's the exact gap our Board Compliance Kit is built for: a one-time $199 tool that organizes your building's specific SIRS and milestone timeline, tracks reserve funding status, and helps the board communicate the schedule to owners clearly. It doesn't do the inspection or the study; only a licensed engineer, architect, or reserve specialist can do that.
Frequently asked questions
What is a reserve study?
A reserve study is a professional assessment of a building's major shared components (roof, structure, plumbing, paving, and more) that projects each item's remaining life and replacement cost, then builds a funding schedule so the association saves enough over time instead of relying on surprise special assessments.
What is a reserve study for an HOA?
For an HOA, a reserve study evaluates shared community assets, roads, clubhouse, pool, roofs on common buildings, and estimates when each will need replacement and how much it will cost, so the board can set realistic monthly dues instead of guessing or underfunding reserves.
What is an HOA assessment?
An HOA assessment is a fee owners in a homeowners association pay to cover shared expenses: landscaping, insurance, amenities, and reserve savings. It can be a regular recurring charge set in the annual budget or a special, one-time charge levied when an unbudgeted cost or shortfall comes up.
How much should an HOA have in reserves?
There's no fixed statutory percentage. The honest answer is whatever a current reserve study calculates each specific component needs, based on its age, condition, and replacement cost. Some reserve professionals use roughly 70% of "fully funded" as a rough health benchmark, but it's a guideline, not a legal requirement for most HOAs.
How much does a reserve study cost?
Typical Florida condo reserve studies run roughly $3,000 to $8,000 for smaller buildings and $10,000 to $20,000 or more for larger high-rises needing a full SIRS-compliant structural review. Get multiple bids from licensed engineers or reserve specialists since there's no fixed statewide fee schedule.
Are HOA or condo special assessments tax deductible?
Generally no, for a personal residence. Special assessments for repairs or reserves aren't itemized deductions like mortgage interest. For rental property, part of the assessment may add to cost basis or qualify as a deductible repair expense; casualty-loss assessments after a federally declared disaster may qualify separately. Talk to a CPA about your specific situation.
What's the difference between a regular assessment and a special assessment?
A regular assessment is the recurring, budgeted charge set in the annual budget that funds operations and reserves. A special assessment is a one-time or short-series charge the board levies outside the budget cycle to cover an unbudgeted cost, like storm damage or a SIRS-driven reserve shortfall.
Can a condo board levy a special assessment without an owner vote?
Usually yes. Most Florida condo declarations let the board levy special assessments by board resolution at a properly noticed meeting, without a separate owner vote, unless the declaration specifically requires one. Owners still get statutory notice rights and access to supporting financial documentation.
What happens if I can't pay a special assessment?
Unpaid assessments become a lien on your unit under Florida Statute 718.116, and the association can charge interest and late fees and eventually foreclose the lien. Some boards offer payment plans for large SIRS-related assessments, but this is discretionary, not required. Talk to the board and a real estate attorney early if you're at risk of default.
Why are Florida condo special assessments getting so much bigger now?
Two post-Surfside laws are driving it: the Milestone Inspection requirement (Florida Statute 553.899) for buildings 3+ stories, and the SIRS reserve mandate (718.112) which bars waiving reserve funding for structural components starting with reserve years after December 31, 2024. Buildings that underfunded reserves for years now face large catch-up costs at once.
Does every condo building need a SIRS or Milestone Inspection?
The requirements apply to condo and cooperative buildings that are three stories or more in height. Milestone Inspections are due at 25 years (within 3 miles of the coast) or 30 years (inland) from the certificate of occupancy, then every 10 years. SIRS deadlines and scope depend on building size and turnover status; confirm specifics with your association's counsel and county building department.
Is a reserve study the same thing as a SIRS?
No. A SIRS (Structural Integrity Reserve Study) is a specific, statutorily defined study of structural components (roof, load-bearing walls, foundation, plumbing, and more) required for Florida condo buildings 3+ stories under 718.112. A general reserve study can cover a broader range of components, including non-structural ones, and isn't always legally mandated the same way.
