The Behavioral Health Services Act

The Behavioral Health Services Act (BHSA) passed as Proposition 1 by the California voters on March 5, 2024. BHSA includes two components: Behavioral Health Infrastructure Bond Act (AB 531) and the Behavioral Health Services Act (SB 326). BHSA signifies a philosophical shift from prevention, intervention, and treatment across the mental health spectrum to focus on the most severely mental ill individuals. It allows for the inclusion of eligible programs for those with substance use conditions and places significant importance on housing and homelessness. There is a statewide commitment to increased accountability and transparency in how BHSA funds will be reported.
