Welf. & Inst. Code, § 636.2

The probation officer may operate and maintain nonsecure detention facilities, or may contract with public or private agencies offering such services, for those minors who are not considered escape risks and are not considered a danger to themselves or to the person or property of another. Criteria to be considered for detention in such facilities shall include, but not be limited to: (a) the nature of the offense, (b) the minor’s previous record including escapes from secure detention facilities, (c) lack of criminal sophistication, and (d) the age of the minor. A minor detained in such facilities who leaves the same without permission may be housed in a secure facility following his apprehension, pending a detention hearing pursuant to Section 632.
