📉 2. Request an Informal Value Review

If you believe your property's assessed value exceeds its current market value, you can request a free informal review from the Contra Costa County Assessor's Office. This is especially pertinent if property values in your area have declined. To initiate this process, complete the appropriate form available on the county's Review Your Value page.Contra Costa County+2Contra Costa County+2Contra Costa County+2

📝 3. File a Formal Assessment Appeal

If the informal review doesn't yield a satisfactory result, you can file a formal assessment appeal. The filing period for regular assessments is from July 2 to November 30 each year. For supplemental or escape assessments, you must file within 60 days of the notice date. The application form and detailed instructions are available on the Assessment Appeals page.
