County Jail #3 is San Francisco’s current large-capacity county jail at 1 Moreland Drive, San Bruno, CA 94066. The current sheriff page states that it opened in 2005, was formerly known as County Jail #5, and can house up to 768 people.
The same current sheriff page says County Jail #3 offers some of the Sheriff’s Office’s most extensive and original programs and classes and, beginning February 1, 2026, provides a free on-demand Flywheel transportation service for visitors traveling to the jail in San Bruno. The current public page does not publish a direct jail phone line in its contact block, so this record uses the current address and website as the primary public contact path.
