The County Assessor has processed almost all of the Calamity Damage Reassessments as of March 2018. Please be patient with the process if you have not received a notice yet. Once we have determined your new assessed value you will receive a “Notice of Correction to the 601 Assessment Roll” informing you of the new assessment. If you not received this notice by April 5, 2018, please contact the Sonoma County Assessor’s office at (707) 565-1888.
