About the Contra Costa County Sheriff's Office:

The 720 sworn personnel and 332 civilian personnel of the Contra Costa County Sheriff’s Office are organized into four bureaus: Administrative Services Bureau; Custody Services Bureau; Field Operations Bureau; and, the Support Services Bureau.

The Custody Services Bureau operates three detention facilities within the Detention Division, which are located in Marsh Creek, Martinez and Richmond. The three facilities average an inmate population in excess of 1,500. Custody Alternative and inmate transportation are also responsibilities of the Detention Division. Deputy Sheriffs provide security for the Superior Courts as well as Commissioners. The Marshal’s Office, with its accompanying duties pertaining to the Courts, was merged with the Office of the Sheriff in 1988, and now constitutes the Court Security Division within Custody Services Bureau.

The Field Operations Bureau consists of three service divisions: Patrol, Investigation and Coroner's. The Patrol Division provides patrol services for the unincorporated area of the County; the five contract cities of Danville, Lafayette, Oakley, Orinda and San Ramon; and the special districts in Alamo, Blackhawk, Crockett, Diablo and Roundhill; as well as contracted services with the Contra Costa County Housing Authority, A.C. Transit, the Contra Costa Water District and Contra Costa Regional Medical Center.

The Investigations Division is responsible for follow-up investigation of all reported felony offenses and certain misdemeanor crimes that occur in unincorporated areas. The Investigations Division investigates roughly 9,400 felony and misdemeanor crimes annually, to include homicides, robberies, burglaries, as well as all sex crimes and narcotics violations. Detectives are assigned to Narcotic Enforcement Teams (NETS), which are staffed by local law enforcement agencies and supervised by the Department of Justice (DOJ) and Bureau of Narcotic Enforcement (BNE) Agents. Detectives also provide service to contract cities and special districts.

The branch of Administrative Services is one of the four Bureaus in the Office of the Sheriff. Five distinct units described below provide the majority of services performed by this Bureau: Inspections and Control, Personnel and Finance, Planning and Research, Professional Standards and Employee Development. The Office of the Sheriff has its own Crime Laboratory, which provides service to all law enforcement agencies in the County and is known for its excellence.

The Communications Center dispatches for all Sheriff’s patrol units and contracted services, as well as all emergency medical and Animal Control services countywide. Annually, 800,000 phone calls are received in the Dispatch Center. The communications center was recently upgraded and remodeled.
