Lassen County, California, has about 28,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Lassen County depends on where the incident happened: the Lassen 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 Lassen County
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
In Lassen County that is the Lassen 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 Susanville Area Office in Lassen 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 Lassen County (other agency) and California Department of Forestry and Fire Protection at Lassen-Modoc (state agency), each with a records office of its own.
