Booking: Where People Arrested in Tuolumne County Are Held
The county jail is where a person arrested in Tuolumne County and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2025 the jail held about 130 people, down from about 140 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 147 beds, and it ran at 98 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 Tuolumne County
For Tuolumne County the place to look is the case index of the Superior Court of California, County of Tuolumne, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at tuolumne.courts.ca.gov/divisions/criminal, phone (209)588-5450).
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.
