How Contra Costa Booking Works

The main Contra Costa County detention facility is at 1850 Muir Road in Martinez. This is where most county bookings are processed. The sheriff's office runs custody services around the clock. You can reach them any time at (925) 646-4496. Arrests made anywhere in Contra Costa County typically end up at this facility for booking and intake.

Local police departments across Contra Costa County bring arrested people to the county jail for processing. That includes agencies from cities like Concord, Richmond, Antioch, Walnut Creek, and Pittsburg, among others. The city officers handle the arrest, but the Contra Costa County Sheriff's staff run the booking at the detention facility. They take the person's photo, log their personal details, and record every charge. This creates the booking record that appears in the in-custody reports system.

Contra Costa County handles a high volume of bookings due to its large population. New records generally appear in the online system within a few hours of intake, though busy periods may cause slight delays.

Contra Costa County Arrest Record Data

State law dictates what Contra Costa County must include in its public booking records. Under Government Code Section 7923.610, the sheriff must release the full name and occupation of the arrested person, their physical description and date of birth, the arrest and booking times, the location of the arrest, the charges, the bail amount, and the release or holding status.

The in-custody reports for Contra Costa County show most of this information. Charges are listed with their code sections. Bail is shown per charge and as a total. The booking date tells you when the person entered the county system. If multiple agencies were involved, the arresting agency may be noted. This level of detail makes the Contra Costa County database one of the more informative public booking tools in the Bay Area.

Under Penal Code Section 13300, local criminal justice agencies compile master records that include booking numbers, arrest dates, charges, and dispositions. The Contra Costa County Sheriff maintains these records as part of its operational database. Some of this data feeds into the public-facing in-custody reports system.

Contra Costa Records and the CPRA

The California Public Records Act ensures Contra Costa County booking records stay accessible to the public. Anyone can search. There is no fee for using the online system. If you need records that go beyond what the in-custody reports show, submit a formal public records request to the Contra Costa County Sheriff. The California DOJ public records page outlines the process and timelines.

Agencies must respond within 10 days. They can take a 14-day extension if needed. Copying fees are usually in the range of 10 cents per page, though Contra Costa County may set its own rates. For older Contra Costa County booking records that have cycled out of the online system, a written request is your best bet. Include the person's name and approximate arrest date to speed things up.

Sealed records will not appear in any search. Under Penal Code Section 851.91, people arrested but not convicted can petition to seal their arrest records. If a Contra Costa County booking has been sealed by court order, it is gone from public view.

Note: The in-custody reports system shows current and recent inmates, not a complete historical archive of every Contra Costa County booking.
