Sonoma County Jail – Main Adult Detention Facility
The Main Adult Detention Facility (MADF) is one of the jails operated by the Detention Division of the Sonoma County Sheriff’s Department. The department is responsible for the processing, care and management of inmates being held in detention. The Detention Division is staffed with over 300 employees.
This Main Adult Detention Facility is designed to give “direct supervision” rather than the previous “linear” design of earlier jails in Sonoma County. It is constructed to house up to 790 inmates. The facility houses medium and maximum security inmates, both pre-trial and sentenced.
The direct supervision is designed to allow the officers to make contact with inmates, encourageing the use of interpersonal skills. Currently there are 145 Correctional Deputies, 18 sergeants, 5 lieutenants, and one captain at this facility.
