At the time a minor is involuntarily admitted to an evaluation and treatment facility, secure withdrawal management and stabilization facility, or approved substance use disorder treatment program, the professional person in charge or his or her designee shall take reasonable precautions to inventory and safeguard the personal property of the detained minor. A copy of the inventory, signed by the staff member making it, must be given to the detained minor and must, in addition, be open to inspection to any responsible relative, subject to limitations, if any, specifically imposed by the detained minor. For purposes of this section, “responsible relative” includes the guardian, conservator, attorney, parent, or adult brother or sister of the minor. The facility shall not disclose the contents of the inventory to any other person without the consent of the minor or order of the court.
