A peace officer may take or authorize a minor to be taken into custody and immediately delivered to an appropriate crisis stabilization unit, evaluation and treatment facility, secure withdrawal management and stabilization facility, approved substance use disorder treatment program, or the emergency department of a local hospital when he or she has reasonable cause to believe that such minor is suffering from a behavioral health disorder and presents an imminent likelihood of serious harm or is gravely disabled. Until July 1, 2026, a peace officer’s delivery of a minor to a secure withdrawal management and stabilization facility or approved substance use disorder treatment program is subject to the availability of a secure withdrawal management and stabilization facility or approved substance use disorder treatment program with adequate space for the minor.
