A special assessment is a one-time charge an HOA levies on top of regular dues, usually to cover a major expense the reserve fund can't absorb — a new roof, storm damage, an elevator overhaul, or a legally mandated structural repair. Unlike regular dues, which are predictable and budgeted for, special assessments often arrive with little warning and can be a serious financial shock.
Why they happen
- Underfunded reserves — the most common cause. See our reserve funds guide for how to check this before you buy.
- Unexpected damage — storms, fires, or other events not fully covered by insurance.
- New legal requirements — some states have passed mandatory structural inspection and reserve-funding laws for condo buildings following high-profile safety incidents, forcing associations that hadn't planned for these costs to assess quickly.
- Litigation costs — legal fees from a lawsuit the association is involved in.
How much do they typically cost?
There's no standard number — special assessments can range from a few hundred dollars per household for a modest shared repair to tens of thousands of dollars per unit for a major structural project in a condo building. The amount is usually divided among owners based on the same formula used for regular dues (often equally per unit, or by square footage/ownership percentage).
Can you pay it over time?
Sometimes. Many associations offer a payment plan for special assessments, especially large ones, rather than requiring a lump sum. This isn't guaranteed — it depends on the association's own cash flow needs for the project and what the board decides. It's worth asking directly and, if a plan isn't offered, requesting one, particularly if the amount is a genuine hardship.
Can you dispute a special assessment?
Disputing the fact that money is needed for a legitimate, properly authorized expense is difficult — if the board followed the correct process (often requiring notice, sometimes a membership vote depending on the amount and your governing documents), the assessment is generally enforceable the same way regular dues are, including liens for nonpayment. What you can scrutinize:
- Was proper notice given, and was the required approval process (board vote, or membership vote if the amount exceeds a threshold in your CC&Rs) actually followed?
- Is the amount reasonable relative to the actual cost of the project, with documentation to back it up?
- Could this have been avoided with better reserve planning — worth raising even if it doesn't get you out of paying, since it's relevant to future board decisions and, if egregious, potential mismanagement (see our guide on spotting HOA fraud).
