The San Mateo County Sheriff's Office operates both the Macguire Correctional Facility and the Maple Street Complex Facilities. The Macquire Correctional Facility houses the men's jail and the Maple Street Complex Facilities houses the women's jail and transitional facilities for men and women.
The San Mateo County Sheriff's Office notes that each facility provides incarceration and rehabilitation services for pre-trial and sentenced inmates. The jails and their staff members make certain that inmates appear in court, serve their sentences and receive opportunities to improve their lives and avoid returning to jail once released. They also ensure that inmates' medical, hygienic, nutritional, legal and spiritual needs are met.
