Cal. Welf. & Inst. Code § 236

Notwithstanding any other law, probation departments may engage in activities designed to prevent juvenile delinquency. These activities include rendering direct and indirect services to persons in the community. Probation departments shall not be limited to providing services only to those persons on probation being supervised under Section 330 or 654, but may provide services to any juveniles in the community. Services or programs offered to minors or minors’ parents or guardians who are not on probation are voluntary and shall not include probation conditions or consequences as a result of not engaging in or completing those programs or services. For minors not on probation, the provision of services or programs under this section shall not be construed to allow probation departments to maintain a formal or informal caseload, establish formal or informal contracts with minors or minors’ parents or guardians, or create mandated-probation conditions.
