CA AB2099

Amends Section 5150 of the Welfare and Institutions Code regarding involuntary psychiatric detention procedures for individuals deemed dangerous or gravely disabled due to mental health disorder.

Requires that a copy of the written application documenting the circumstances and probable cause for detention shall be treated as the original document.

Mandates that facilities provide detained persons with oral and written advisements in accessible language explaining the reasons for detention, their rights, and the 72-hour evaluation period.

Requires facilities to maintain records documenting whether advisements were completed, including the name of the person giving the advisement, date, language used, and statement of good cause if advisement was not completed.

Preserves the requirement that professional staff assess whether a person can be served without detention and offer alternative services when appropriate.
