Juvenile Records and Exclusions
Juvenile offenders are not listed in the adult inmate search. They are processed through the separate juvenile justice system and housed in dedicated facilities.

Bail and Bond Information

Frequently Asked Questions
Many people have questions about how to use the inmate search, what data is included, and how to get help. Below are answers to the most common inquiries based on official Sheriff’s Office guidelines and public records policies.
How often is the inmate search database updated?
The Contra Costa County Inmate Search database refreshes every 15 minutes across all facilities. This ensures that new bookings, releases, transfers, and court updates appear almost immediately. The Martinez Detention Facility updates its roster every 30 minutes due to high intake volume. These frequent updates help families, lawyers, and researchers stay informed without delays.

No manual refresh is needed—the page loads the latest data automatically.
Can I search for someone using only a first name or nickname?
No, the search tool requires both a first and last name to return results. Partial names, nicknames, or aliases alone will not work unless entered as the full legal name. However, the system does display known aliases once a match is found. For example, if “Robert” is listed as “Bob,” it will appear under the main record. If you’re unsure of the exact spelling, try common variations. The Sheriff’s Office recommends calling (925) 335-1500 for assistance if the search fails. Staff can help verify names or check alternate spellings in the database.
Are juvenile inmates included in the search results?
No, juvenile offenders are not listed in the adult inmate search. They are handled by the Contra Costa County Juvenile Justice System and housed in separate facilities. Their records are confidential under California law. Only law enforcement, court personnel, and authorized family members can access juvenile data. If you believe a minor is in custody, contact the Juvenile Court at (925) 646-5000. The adult roster only includes individuals 18 years or older booked into county jails.

How long does it take for an inmate to be released after bail is posted?
Once bail is paid, release usually occurs within two hours. The process includes paperwork, property return, and final clearance. Weekends and holidays may cause slight delays.
