The Assessment Appeals Board handles differences over the valuation of property that cannot be resolved by discussion with the Assessor's Office. This is an independent board composed of private citizens appointed by the County Board of Supervisors. They consider all evidence presented by the property owner and the Assessor's Office at a formal hearing. The Appeals Board then establishes the value of the property in question.

Appeals on regular assessments must be filed between July 2^nd and November 30^th for unsecured and secured property.

Appeals on supplemental assessments must be filed no later than 60 days after the date of mailing printed on the tax bill or the postmark, whichever is later. 

Appeals forms are available from the Clerk of the Board Appeals web page
