Special assessment: the bill that shows up after you buy

What it is, in one sentence

It is an extraordinary charge the association splits among all owners when something has to be paid for that reserves do not cover: the roof, the facades, the garage, the plumbing. It is not the monthly fee. It is separate, and it can run from a few thousand to tens of thousands per unit.

And here is the part people miss: it is paid by whoever owns the unit when the charge comes due, not by whoever lived there while the building aged. Buy in March, approved in June, it is yours. And if it was approved before you bought and went unpaid, that is yours too: Florida law makes you jointly and severally liable with the previous owner for whatever came due up to the transfer of title.

Why this got serious in Miami

After the Surfside collapse in 2021, Florida changed the rules. Buildings three habitable stories and up must run structural integrity studies and, above all, keep reserves funded for major repairs. Before that, many associations voted year after year not to fund them and pushed the problem forward. Since 2025 the rule is no longer absolute: an association that completed the state milestone inspection —which is not the county recertification— within the previous two calendar years can vote to pause or reduce reserve contributions for up to two consecutive budgets to fund the repairs that inspection recommends, and that applies to budgets adopted through December 31, 2028.

The result is that a lot of Miami-Dade buildings are catching up all at once. That is the adjustment being paid right now, and it is why you see condos that look impossibly cheap and are not.

What you can check before signing

None of this is secret. Part of it the law requires the seller to hand over and pay for; the rest the association keeps and you ask for:

• Association minutes from the last two years. That is where the work gets discussed long before it is approved. If they have spent a year talking about the roof, the roof will be paid for.
• The state of the reserves. How much there is and what it is earmarked for. Low reserves in an older building is a pending bill, not a coincidence.
• Two reports, and they are not the same paper. The state milestone inspection says what has to be repaired, and when it finds substantial structural deterioration the work must begin within 365 days at the latest; the seller hands you the inspector-prepared summary of it. The reserve study says how much money has to be set aside, and if the association has not done one the seller must hand you a statement saying so. That statement is an answer too.
• Assessments already approved or up for a vote. If one exists, you need to know whether the seller pays it in full at closing or passes it to you.

Beyond the paperwork, look at the building. Rust on railings and balconies, cracks that follow a line, damp patches repeating at the same spot across floors, fresh paint on one face only. None of those proves anything alone. Several together say plenty.

How it changes your math

An assessment does not only change what you pay: it can change whether you get approved. The lender looks at your DTI with the monthly fee included, and some programs will not lend at all in buildings with unresolved structural issues.

Which is why this is worth knowing before you fall for the unit, not after the inspection.
