The California Association of Area Agencies on Aging (C4A) is a nonprofit organization representing California's 33 area agencies on aging. The association is an advocate for meeting the needs of seniors and adults with disabilities, with the purpose to implement the provisions and intent of the Older Americans Act and the Older Californians Act.
Area agencies on aging, established by the federal Older Americans Act in 1965, receive federal, state, and local funds to contract with local organizations for service to seniors. There are 33 area agencies on aging designated by the California Department of Aging as the local Planning Services Agencies
The Mello-Granlund Older Californians Act (AB2800), signed into law in 1996, moved the primary focus for the delivery of services from the State to the local level. It identified area agencies on aging as the local units in California to administer programs in compliance with the Older Americans Act, the Older Californians Act, and other applicable regulations.
California’s area agencies on aging incorporated in 1979 as the California Association of Area Agencies on Aging—a statewide, nonprofit organization advocating for seniors and persons with disabilities.
