Fairfax, California, in Marin County, has about 7,500 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city 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 Marin. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Fairfax
The FBI lists Fairfax with an arrest reporting agency of its own, filed as Fairfax Police Department. It reported 77 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Marin County Sheriff's Office is the county agency. It reported 874 arrests for 2023.
The FBI's agency list also places these agencies in Marin County: Union Pacific Railroad in Marin County (other); Marin Community College (campus police); the Highway Patrol's Marin Area Office (state police).
How Many Arrests Fairfax Reports
Each agency reports its arrests to the FBI by month, and the FBI publishes them on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Fairfax: 77 for 2025, 101 for 2024, 99 for 2023, 114 for 2022, 148 for 2020 and 210 for 2019; 2021 is missing months.
Fairfax's 77 arrests in 2025 were down 24 percent from 101 in 2024.
Through August 2026, Fairfax reported 62 arrests, against 58 in the same months of 2025.
Across Marin County, the seven agencies with all twelve months of 2025 on file reported 3,134 arrests between them.
Booking: Where People Arrested in Fairfax Are Held
A person kept in custody after an arrest in Fairfax 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 260 people, down from about 280 in 2019. Its rated capacity in 2023, the last year with a capacity figure, was 386 beds, and it ran at 65 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 Fairfax
An arrest in Fairfax can be traced in two places, depending on where the case stands: the case index of the Superior Court of California, County of Marin, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at marin.courts.ca.gov/divisions/court-records-exhibits, phone (415) 444-7080); the District Attorney, which decides whether an arrest becomes a charge (its page is at marincountyda.org/our-team, phone (415) 473-6450).
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 Fairfax
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.
