Reviewed and updated October 9, 2026 by the SearchSystems.net editorial team. The arrest and crime counts are the ones each agency reported to the FBI, as the FBI held them on October 8, 2026. Every office link was opened and checked against the office's own site on September 23, 2026.
Sonoma County, California, has about 485,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Sonoma County depends on where the incident happened: the Sonoma County Sheriff's Office for the unincorporated county, the agency that reports for the city inside a city. This guide names each agency, where its records page is and what the California Public Records Act requires of it.
This guide covers which agency, the sheriff's reports, the cities' reports, how many reports, what the law requires and common questions.

Which Agency Holds a Report from Sonoma County
The report of an incident is released by the agency that took it; the court and the jail hold their own records of the same event, but not the report.
In Sonoma County that is the Sonoma County Sheriff's Office for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
The FBI's list also places the Highway Patrol's Santa Rosa Area Office in Sonoma County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's agency list also places three state agencies, two campus police departments and one other agency in Sonoma County, each with a records office of its own.

The California Public Records Act sets the rules: an answer within 10 days, with up to 14 more days in unusual circumstances, at a charge of the direct cost of copying only, not staff time, from the agency that holds the report.
Any other county record goes through the county records request page SearchSystems verified, at sonomacounty.gov/administrative-support-and-fiscal-services/clerk-r... (page title: Public Records Requests | Clerk-Recorder-Assessor).
A defendant who has been charged gets the report through the case: the District Attorney handles discovery for pending cases.
