Cal. WIC § 3300

There is hereby established an institution and branches, under the jurisdiction of the Department of Corrections and Rehabilitation, to be known as the California Rehabilitation Center. Branches may be established in existing institutions of the Department of Corrections and Rehabilitation, Division of Adult Operations, in halfway houses as described in Section 3153, in such other facilities as may be made available on the grounds of other state institutions, and in city and county correctional facilities where treatment facilities are available. Branches shall not be established on the grounds of such other institutions in any manner which will result in the placement of patients of such institutions into inferior facilities. Branches placed in a facility of the State Department of State Hospitals shall have prior approval of the Director of State Hospitals, and branches placed in a facility of the State Department of Developmental Services shall have the prior approval of the Director of Developmental Services. Commencing July 1, 2005, the branches in the Department of Corrections and Rehabilitation, Division of Juvenile Facilities shall be established by order of the secretary, and shall be subject to his or her administrative direction. Branches placed in city or county facilities shall have prior approval of the legislative body of the city or county.

Persons confined pursuant to this section in branches established in city and county correctional facilities shall be housed separately from the prisoners therein, and shall be entitled to receive treatment substantially equal to that which would be afforded those persons if confined in the main institution of the California Rehabilitation Center.
