Candidate Filing

This page is used to provide forms and information to candidates for elected offices, including what forms are needed for specific types of offices. The information and forms are provided as a convenience for candidates, and it is up to the individual filing for an elected office to ensure they have the correct forms and file with the correct agency.

COVID-19 Procedures

Beginning July 13th, candidates may e-mail their filing documents for review to ROV-Candidate@sonoma-county.org. Please note that the office will not review documents for accuracy, only verify that the documents are complete. Once documents have been verified, candidates can make an appointment to take their oath either in the office or via online video conference by calling 707-565-6800. Completed documents with original signatures must be received by our office no later than 5pm on August 7th (postmark does not count). Candidates may submit documents with original signatures, M-F from 8am-5pm, by appointment, in the office drive-thru drop box, or via mail or other delivery service.
