Napa County, California, has about 133,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Napa County depends on where the incident happened: the Napa 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 Napa 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 Napa County that is the Napa 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 Napa Area Office in Napa County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's list also carries Union Pacific Railroad in Napa County and the Napa Special Investigations Bureau (other agency) and Napa State Hospital (state agency), each with a records office of its own.
