How this calculator works
Subtract the reserve funds the board will apply from the total project cost, then divide the shortfall among the units. Spread it over the installment period to see the monthly amount.
Formula: (project cost − reserves applied) ÷ units, then ÷ months for installments. Many governing documents and states require owner approval for special assessments above a set amount, and some limit how they’re collected.
Estimates only, not financial or legal advice. Results depend on your governing documents and state law.

Do owners have to vote on a special assessment?
Often, above a certain amount. Your governing documents and state law set the threshold and the vote required.
How can an HOA avoid special assessments?
Following a reserve study and funding reserves each year is the best way to avoid them.
