On October 30, 2001, Sonoma County merged two previously separate departments, the Clerk-Recorder and the Assessor, into the combined Sonoma County Clerk-Recorder-Assessor-Registrar of Voters Department. This merger is an effort to provide better-integrated, efficient, and public-focused services to you, the Sonoma County taxpayer.
The Assessor’s Office is responsible for providing accurate and timely property assessments and for determining eligibility for various property tax exemptions and exclusions.
The County Clerk Division of the Clerk-Recorder-Assessor Department has a variety of duties, including issuing marriage licenses, filing fictitious business name statements, processing notary bonds, handling environmental documents, and performing civil marriage ceremonies. The County Clerk Division also issues certified copies of marriage, birth and death records on behalf of the County Recorder.
The Recorder maintains various land and finance documents for Sonoma County. Typical land documents include deeds, leases, mining claims, subdivision maps, homestead declarations and records of survey. Typical finance documents include trust deeds, notices of default, reconveyances, and various liens. This division of the Clerk-Recorder-Assessor also collects the Documentary Transfer Tax when real property exchanges hands.
The Registrar of Voters registers Sonoma County voters and maintains the County’s voter registration file, conducts federal, state and local elections held in the county, files candidates’ campaign statements, and performs various other duties related to elections.
