Behavioral Health Services Act

BEHAVIORAL HEALTH SERVICES ACT (BHSA)

The Behavioral Health Services Act (BHSA), approved by California voters through Proposition 1 in March 2024, modernizes and replaces the Mental Health Services Act (MHSA). BHSA became effective July 1, 2026. 

BHSA supports behavioral health services for individuals with serious mental health conditions and substance use disorders. It places greater emphasis on housing, intensive services for individuals with the most complex needs, early intervention, workforce development, accountability, and measurable outcomes.  

Funding continues to come primarily from a one-percent tax on personal income over $1 million. 

BHSA Funding Categories 

County BHSA funding is organized into three primary categories: 

Behavioral Health Services and Supports 

Thirty-five percent of county BHSA funding is allocated to Behavioral Health Services and Supports. This category may include: 

•    Children’s, adult, and older adult systems of care  
•    Early intervention programs  
•    Outreach and engagement  
•    Workforce education and training  
•    Capital facilities and technological needs  
•    Innovative behavioral health pilots and projects  

At least 51 percent of Behavioral Health Services and Supports funding must be used for early intervention. At least 51 percent of early intervention funding must serve individuals age 25 and younger.  

Full Service Partnership Programs 

Thirty-five percent of county BHSA funding is allocated to Full Service Partnership programs. 

Full Service Partnerships provide comprehensive and intensive treatment and support for individuals of any age who have the most significant behavioral health needs. Services may include behavioral health treatment, care coordination, employment assistance, peer support, and other services needed to promote stability and recovery.  

Housing Interventions 

Thirty percent of county BHSA funding is allocated to Housing Interventions for eligible individuals with significant behavioral health needs who are experiencing homelessness or are at risk of homelessness. 

Housing Interventions may include rental and operating subsidies, shared housing, family housing, certain transitional rent costs, and capital development. Fifty percent of Housing Intervention funding is prioritized for individuals experiencing chronic homelessness, and no more than 25 percent may generally be used for capital development.  

Substance Use Disorder Services 

A significant change under BHSA is the inclusion of services for eligible individuals with substance use disorders. This allows counties to plan and fund mental health and substance use disorder services as part of a more coordinated behavioral health system.  

Integrated Plan 

Under BHSA, counties prepare a three-year Integrated Plan for Behavioral Health Services and Outcomes. The Integrated Plan describes how the County will use BHSA and other behavioral health funding to provide services, address local needs, and improve outcomes. 

Siskiyou County’s first BHSA Integrated Plan covers Fiscal Years 2026–2027 through 2028–2029. The planning process includes community input, a public-comment period, a public hearing, approval by the Siskiyou County Behavioral Health Board, and approval by the Siskiyou County Board of Supervisors.  

Community Participation 

Community input is an important part of BHSA planning. Siskiyou County invites individuals receiving behavioral health services, family members, providers, Tribal partners, community organizations, schools, law enforcement, healthcare partners, and other interested residents to participate in the planning process. 
Information about upcoming meetings, public-comment opportunities, plans, reports, and other BHSA documents will be posted on this page.
