Agency-owned or operated facilities that provide an alternative living environment for adults with developmental disabilities, sensory impairments, physical disabilities, emotional disabilities, multiple disabilities or chronic illnesses such as AIDS who are in need of personal services, supervision and/or assistance essential for self-protection or sustaining the activities of daily living and consequently are unable to live with their own families or in a more independent setting. Group residences for adults with disabilities may be licensed by the state and may be distinguished according to the level of service residents require. Service levels depend on the self-care skills residents possess, their limitations in the areas of physical coordination and mobility, and the presence and extent of behavior problems including disruptive or self-injurious behavior.
