San Joaquin County Jail Jail Core

Jail Core is one of three facilities operated by the San Joaquin County Sheriff's Office. The other two are South Jail and Honor Farm. Jail Core serves as the county intake center for those who are arrested. The facility provides detention services for inmates who have not made bail, as well as those who've been sentenced to county jail time. 

A primary function of the jail is to provide facilities for secure confinement. All facilities provide housing and services of equal quality for all persons. Juveniles are not detained in the facility.

Detention facilities are only a part of the San Joaquin County Criminal Justice System. The organization endorses the full development and use of alternatives to incarceration. Including a diversion program as alternative to prosecution, as well as bail and OR releases instead of detention.

Jail Core is managed under the direct supervision concept, which means all inmates are confined under the least restrictive conditions, based on their behavior. 

Inmates who adhere to facility rules, follow the directions of staff, and do not cause problems receive free access to make collect phone calls, visiting, recreation, religious, and education services. 

The facility restricts some or all privileges for inmates who display disruptive behavior.

Alternatives to incarceration include community service, restitution, work or education furlough, county parole, alternative work program (AWP), and home detention.
