Mental Health Services - Oversight And Accountability Commision

Right Column


More than 2 million children, adults, and seniors are affected by potentially disabling mental illnesses every year in California. Thirty years ago, the State of California cut back on its services in state hospitals for people with severe mental illnesses, without providing adequate funding for mental health services in the community. Many people became homeless.

To address this issue, Proposition 63 was approved by voters in 2004. Proposition 63, also called the Mental Health Services Act, was enacted into law on January 1, 2005.  It places a 1% tax on personal income above 1 million dollars; since that time, it has generated approximately $8 billion.

Proposition 63 emphasizes transformation of the mental health system while improving the quality of life for Californians living with a mental illness.


The MHSA consists of the following components:

  • Community Services & Support
  • Capital Facilities and Technological Needs
  • Workforce Education & Training
  • Prevention & Early Intervention
  • Innovation

There are sequential phases of development for each of the five components of the Act. Each includes a stakeholder process.

The MHSOAC reviews all County Prop 63 plans and updates; and approves Innovation programs.
