note: This is not an assessment appeal, please see "Application for Assessment Appeal" below. 


The property owner has the right to file an appeal. Butte County has a three-member Assessment Appeal Board appointed by the Board of Supervisors, and a Hearing Officer. They consider all evidence presented by the property owner and by the Assessor's staff at a formal hearing. The Appeals Board, or the Hearing Officer, determine the assessment for the property in question. 

Assessment Appeal Filing Periods are as follows: 

  • Supplemental Assessment - no later than 60 days after the date on which the assessee was notified by Supplemental Assessment Notice. 
  • Regular Assessment - July 2 through November 30. 

Assessment Appeals are filed with the Clerk of the Board of Supervisors in Oroville.
