Last reviewed: October 2026. General information only, not legal advice. The rules depend on your governing documents and the law where the building is.
The letter usually arrives after a meeting most owners didn’t attend. The roof failed an inspection, or the insurer dropped the building, or an engineer found corroded rebar in the parking garage. The board has voted, and every owner now owes a share. Sometimes it’s a few hundred dollars. Sometimes it’s more than the car in the driveway is worth.
That is a special assessment. In Australia it’s a special levy; in English leasehold flats it usually shows up as a major-works service charge. Whatever the name, it is a one-off charge on top of your regular fee, used when the money in reserves or insurance isn’t enough for a specific cost (CAI Foundation for Community Association Research).
This guide covers why they happen, what the rules look like in a few major markets, and what you can realistically do, both before one lands and after.
Why special assessments happen
The honest answer is that most special assessments are deferred costs. A roof has a known lifespan. So do elevators, boilers, balcony membranes and supply pipes. If an association has a reserve study and funds it properly, most replacements can be paid from savings. When boards keep fees low to avoid complaints, the bill doesn’t disappear; it moves forward in time and lands on whoever owns the unit when the component finally fails.
There are genuinely unforeseeable causes too. A storm, a fire, a lawsuit against the association, or a sharp jump in insurance premiums or deductibles can blow a hole in a well-run budget. And sometimes the law changes the math. Florida is the clearest recent example.
The Florida example
After the 2021 Champlain Towers South collapse in Surfside, Florida passed rules in 2022 requiring milestone structural inspections for condo and co-op buildings of three or more habitable stories, and a structural integrity reserve study (SIRS) covering eight building elements: roof, structure, fireproofing and fire protection, plumbing, electrical, waterproofing and exterior painting, windows and exterior doors, and other structural items over a set cost threshold (Florida DBPR).
The effect was blunt. Associations that had waived or underfunded reserves for years were suddenly required to fund them, and many turned to special assessments or loans. In 2025, HB 913 gave boards more room: SIRS reserves can now be funded through regular assessments, special assessments, lines of credit or loans, and some associations that recently completed a milestone inspection can temporarily pause or reduce reserve contributions with owner approval (Association Reserves bulletin on HB 913).
Florida’s lesson travels well. If your building is old and your reserves are thin, a law change, an engineering report or an insurer can turn “we’ll deal with it later” into “we need it this year.”
Who can approve one?
This is where location matters most, and where owners are most often surprised.
In many U.S. associations, the board can levy a special assessment up to a limit set by the governing documents or state law, and needs an owner vote above that. California is a well-known example: without owner approval, a board generally can’t impose special assessments that add up to more than 5% of the year’s budgeted gross expenses, though emergencies are an exception (Cal. Civil Code §5605, §5610).
In New South Wales, a special levy is raised at a general meeting of the owners corporation, and owners must get at least 30 days’ written notice to pay (NSW Government).
In England and Wales, a landlord or management company planning major works that would cost any single leaseholder more than £250 must run a formal “Section 20” consultation. Leaseholders get notices, the chance to comment and to nominate contractors, and a 30-day window to respond at each stage. If the landlord skips it, the amount they can recover may be capped at £250 per leaseholder unless a tribunal grants dispensation (Leasehold Advisory Service; GOV.UK).
The takeaway: before you assume an assessment is valid or invalid, read the assessment section of your bylaws or lease, then look up the statute for your state or province. Process failures are one of the few solid grounds for pushback.
How to prepare before one hits
The best defence is information, and most of it is available to you as an owner.
Get the reserve study. If the association doesn’t have a current one, that is your first problem. If it does, look at the component list and the funding level. A building that is well under half funded, with a roof, façade or pipe replacement scheduled in the next five years, has a special assessment in its future unless fees go up.
Read the minutes for words like “engineer,” “inspection,” “insurer,” “non-renewal” and “deductible.” Boards usually see trouble a year or two before owners do.
Check your own insurance. Most condo unit-owner policies include a small amount of loss assessment coverage. On the standard U.S. HO-6 form it is $1,000, and it only applies when the assessment results from a loss the policy would cover, such as wind or fire damage to common property. It does not pay for planned maintenance or for assessments charged by a government body (ISO HO 00 06 form; Washington Office of the Insurance Commissioner). Higher limits are cheap to add and worth considering in older buildings or where the master policy deductible is large.
Keep a cushion. If you own in an older building, treat a few months of fees as a personal reserve. It isn’t glamorous, but it’s the difference between an annoyance and a forced sale.
And if you’re buying, ask the seller and the manager directly whether any special assessments are planned, pending or under discussion. In many jurisdictions the disclosure package has to include this, but “under discussion” can slip through. Get the answer in writing.
When the letter has already arrived
Start by reading it properly. A legitimate notice should explain what the money is for, how much each unit owes and how it was calculated (usually by ownership percentage or unit entitlement), and when it is due.
Then ask for the paperwork behind it: the engineering report, the bids or quotes, the board resolution, and the minutes of the meeting where it was approved. You are entitled to most association records in most jurisdictions, and boards that have done things properly tend to share them without a fight.
Check the process. Was the meeting properly noticed? Was a vote needed and held? In England, was there a proper Section 20 consultation? If the answer is no, you may have grounds to challenge, but understand that a successful challenge usually delays the work rather than cancelling it. The roof still leaks.
Ask about payment plans. Many associations will spread a large assessment over 12 to 60 months, sometimes because they have arranged a loan in the association’s name. That loan will be repaid through higher fees, but it can be far easier on owners than one lump sum. If you need to finance your share yourself, compare a home equity line or personal loan carefully and read the terms before you sign.
If you think the cost is inflated, push for competitive bids. You can also volunteer for a building or finance committee. Owners who show up with questions and some time to help are usually more effective than those who only send angry emails.
Finally, don’t simply refuse to pay. Unpaid assessments become a debt to the association, with late fees and interest, and in many U.S. states a lien that can lead to foreclosure. If you dispute the charge, get legal advice and, where possible, pay under protest while you challenge it.
Can you dispute a special assessment?
Yes, but the ground is narrow. Successful disputes usually rest on process (no required vote, inadequate notice, no Section 20 consultation), on the assessment being outside the association’s powers, or, in leasehold cases, on the cost being unreasonable. In England, leaseholders can apply to the First-tier Tribunal (Property Chamber), and in Wales to the Leasehold Valuation Tribunal, to decide whether service charges are reasonable (GOV.UK). In the U.S., options range from internal dispute resolution to mediation and court, depending on the state. Disagreeing with the board’s judgment that the work is needed is rarely enough on its own.
Frequently asked questions
How much is a typical special assessment?
There isn’t a reliable typical figure. It depends on the project, the size of the building and the reserves already available. Small ones may be a few hundred dollars per unit; major structural or façade work in an underfunded building can run into tens of thousands.
Does insurance cover special assessments?
Only some. Loss assessment coverage in a condo or homeowners policy may pay your share of an assessment caused by a covered loss to common property, up to a limit ($1,000 on the base U.S. HO-6 form). It doesn’t cover routine repairs or upgrades.
Who pays if I sell my unit?
Usually whoever owns the unit when each instalment falls due, but buyers and sellers often negotiate this in the purchase contract. Make sure the contract says so explicitly.
Is a special assessment tax deductible?
On a home you live in, generally not in the U.S., though capital improvements may add to your cost basis. On a rental, part or all may be deductible or depreciable. Ask a tax adviser.
Can a board avoid special assessments altogether?
Not entirely, but a current reserve study, realistic fees and adequate insurance make them rarer and smaller. Most large assessments trace back to years of underfunding.
