HOA special assessment calculator
A special assessment is a one-time charge on top of regular dues, usually for a big repair the reserves can’t cover. See what your share is and what it costs per month if it’s spread out.
The assessment
Your declaration says how assessments are allocated: equal shares, square footage, unit value, or a set percentage.
Payment plan
Used only to show the assessment as a share of the budget. California requires member approval for special assessments over 5% of budgeted gross expenses, with limited emergency exceptions.
Your share
$3,750
Over 12 months: about $312.50 a month.
Simple arithmetic for planning. Your governing documents and the board’s resolution control the actual amount, due dates, and any interest or late fees.
How special assessments get divided
Your declaration (CC&Rs) sets the allocation formula. Many single-family HOAs split assessments equally per lot. Condominiums often use an allocation percentage tied to unit size or value, stated in the declaration. Some communities use square footage. If you don’t know your percentage, it’s usually in an exhibit to the declaration or on your regular dues statement. Use the percentage option above if it’s not an equal split.
Why associations levy them
Associations are supposed to save for predictable big-ticket items, such as roofs, paving, elevators, and pools, through a reserve fund. When reserves fall short, or something unexpected happens (storm damage, a failed building system, a new legal requirement), the board may have to raise the money through a special assessment or a loan. A reserve study estimates how much should be saved. California, for example, requires associations meeting a threshold to have a visual inspection of major components as part of a reserve study at least once every three years, with an annual review. See HOA reserve studies.
Can the board just impose one?
It depends on your state and governing documents. In California, Civil Code § 5605 says the board may not impose special assessments that in total exceed 5% of the association’s budgeted gross expenses for the year, or raise regular assessments more than 20% over the prior year, without approval from a majority of a quorum of members. Exceptions for emergencies are in § 5610. Other states and many declarations set their own voting thresholds, and some let the board act alone. Your governing documents are the first place to look.
Questions to ask the board
- What is the project, and what bids or engineering reports support the cost?
- What does the reserve study say, and why aren’t reserves enough?
- Is a payment plan or an association loan available, and at what interest?
- What happens if an owner pays late? Are there late fees, interest, or lien rights?
- Did the vote follow the governing documents and state law?
A records request is the quickest way to get the reserve study, bids, and minutes behind the decision.
Buying into a community?
Ask the seller and the association whether any special assessment has been approved or is being discussed, and read recent board minutes. A pending assessment can be a large cost. Our before-you-buy checklist covers it.
