Alameda County, California

Alameda County Jail & Detention Center Directory

One of the largest county jails in the entire country, and the real facts families need before making a trip. Available 24 hours a day.

One Jail Anchors The Whole County

Alameda County's custody system is anchored by Santa Rita Jail — the third-largest detention facility in California and the fifth-largest in the country. Unlike counties that split custody across many smaller facilities, Alameda concentrates nearly all of its county-level custody here.

The separate downtown Oakland facility, Glenn E. Dyer Detention Facility, is closed, with custody consolidated at Santa Rita. If you're told a loved one may be at Glenn Dyer specifically — or older paperwork says so — call us and we'll confirm exactly where they are today.
