What to check on your notice
If your 2026 notice shows a higher value than last year, ask why. The typical Big Rock home lost 4.0% over the same stretch. A higher number can still be right for a specific home, for example after a remodel, but the county assessor of property should be able to explain it.

Deadline and where to file
Big Rock values are set by the local county assessor of property. The county Board of Equalization starts its annual session on the first business day of June. The assessor must mail change notices at least 10 days before it starts, and the published notice states the last day the board accepts appeals. Appeal to the county board by that date, or the value can become final for the year.
Reading this in fall 2026? The 2026 deadlines have passed (county board from June 1, 2026; State Board by August 1, 2026 or 45 days after the county decision, whichever is later). Your next chance is the 2027 county Board of Equalization, which opens the first business day of June 2027. Watch for your assessment change notice in spring 2027 and file with the county board before its published last day. If you appealed to the county board this year and lost, check your decision date now, because the State Board window can run 45 days from that notice.
