The purpose of this Act is to promote the operation of community-integrated living arrangements for the supervision of persons with mental illness and persons with a developmental disability by licensing community mental health or developmental services agencies to provide an array of community-integrated living arrangements for such individuals. These community-integrated living arrangements are intended to promote independence in daily living and economic self-sufficiency. The licensed community mental health or developmental services agencies in turn shall be required to certify to the Department that the programs and placements provided in the community-integrated living arrangements comply with this Act, the Mental Health and Developmental Disabilities Code, and applicable Department rules and regulations.
