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.

What is the BHSA Integrated Plan?

The County Integrated Plan is a three-year plan required by the Behavioral Health Services Act that outlines how counties will utilize various behavioral health funding sources (i.e., BHSA, 1991 and 2011 Realignment, federal grant programs, federal financial participation from Medi-Cal, opioid settlement funds, local funding, and other funding) to meet statewide and local outcome measures, reduce disparities, and address unmet needs along the Behavioral Health Care Continuum. The plan must be developed through a transparent community planning process, approved by the county board of supervisors, and submitted via the Department of Health Care Services (DHCS) web-based portal in accordance with Welfare and Institutions Code §5963.02.
