Ownership Changes Backlog
Due to an extraordinary number of ownership changes, the Sonoma County Assessor’s Office is experiencing a significant backlog processing these changes. If you received a tax bill for a property you no longer own, please write “sold” on the bill and return it to our office. Should you need additional assistance please reach out to our office at (707) 565-2281 or email@example.com.
