Placer County, California, has about 434,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Placer County Sheriff's Office, four city agencies and five campus, state or other agencies. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the District Attorney files charges, a case in the Superior Court of California, County of Placer. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Who Makes Arrests in Placer County
The Placer County Sheriff's Office is the county agency that reports arrests to the FBI for Placer County. It reported 3,583 arrests for 2025.
Arrests inside four of the county's cities are reported to the FBI by an agency of the city's own, listed here with the Census population and what each reported:
- Roseville, 163,304 residents: 2,807 arrests reported for 2025.
- Rocklin, 75,129 residents: 891 arrests reported for 2025.
- Lincoln, 56,268 residents: 669 arrests reported for 2025.
- Auburn, 13,780 residents: 332 arrests reported for 2025.
A city on that list is reported separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
The FBI's agency list also places these agencies in Placer County: Union Pacific Railroad in Placer County (other); California Department of Forestry and Fire Protection at Nevada-Yuba-Placer and California State Parks at Sierra (state agency); the Highway Patrol's Auburn and Gold Run Area Offices (state police).
How Many Arrests Each Agency Reports in Placer County

Booking: Where People Arrested in Placer County Are Held
A person kept in custody after an arrest in Placer County is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2025 the jail held about 800 people, up from about 700 in 2019. Its rated capacity in 2017, the last year with a capacity figure, was 803 beds, and it ran at 91 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Placer County
For Placer County the place to look is the District Attorney, which decides whether an arrest becomes a charge (its page is at placer.ca.gov/2923/District-Attorney).
California does not let the public search another person's statewide criminal history. The record kept by the California Department of Justice goes to the person it belongs to and to employers and agencies the law authorizes; for everyone else the court's own case index is the public record of an arrest that led to a charge.
Getting a Copy of an Arrest Record in Placer County
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the California Public Records Act the agency must answer within 10 days, with up to 14 more days in unusual circumstances, and it may charge the direct cost of copying only, not staff time.
