Welf. & Inst. Code, § 207

(a) A minor shall not be detained in any jail, lockup, juvenile hall, or other secure facility if the minor is taken into custody solely upon the ground that the minor is a person described by Section 213.3, or described by Section 601 or adjudged to be such or made a ward of the juvenile court solely upon that ground, except as provided in subdivision (b). If any such minor, other than a minor described in subdivision (b), is detained, the minor shall be detained in a sheltered-care facility or crisis resolution home as provided for in Section 654, or in a nonsecure facility provided for in subdivision (a), (b), (c), or (d) of Section 727.

(b) A minor taken into custody upon the ground that the minor is a person described in Section 601, or adjudged to be a ward of the juvenile court solely upon that ground, may be held in a secure facility, other than a facility in which adults are held in secure custody, in any of the following circumstances:

(1) For up to 12 hours after having been taken into custody for the purpose of determining if there are any outstanding wants, warrants, or holds against the minor in cases where the arresting officer or probation officer has cause to believe that the wants, warrants, or holds exist.

(2) For up to 24 hours after having been taken into custody, in order to locate the minor’s parent or guardian as soon as possible and to arrange the return of the minor to the minor’s parent or guardian, with the exception of an out-of-state runaway who is being held pursuant to the Interstate Compact for Juveniles.

(c) Any minor detained in juvenile hall pursuant to subdivision (b) shall not be permitted to come or remain in contact with any person detained on the basis that the minor has been taken into custody upon the ground that the minor is a person described in Section 602 or adjudged to be such or made a ward of the juvenile court upon that ground.

(d) Minors detained in juvenile hall pursuant to Sections 601 and 602 may be held in the same facility provided they are not permitted to come or remain in contact within that facility.

(e) Every county shall keep a record of each minor detained under subdivision (b), the place and length of time of the detention, and the reasons why the detention was necessary. Every county shall report this information to the Board of State and Community Corrections on a monthly basis, on forms to be provided by that agency.

The board shall not disclose the name of the detainee, or any personally identifying information contained in reports sent to the Division of Juvenile Justice under this subdivision.
