Programs that provide affordable, community-based housing for individuals and families who have experienced long-term or chronic homelessness and have been diagnosed as having a physical or developmental disability, a severe mental illness, substance use disorder problems or HIV/AIDS; or are members of another designated group within the homeless population. Structures may include apartments, single-family houses, duplexes, group homes or single-room occupancy housing. Permanent supportive housing programs generally provide residents with the rights of tenancy under state or local landlord/tenant laws and are linked to services designed to meet residents' needs. Supportive services vary depending on the resident population. Most programs offer some type of case management and housing support, but may also offer more intensive mental health, substance use disorder, vocational, employment or other services which help promote independent living. Supportive services may be offered on-site or off-site, or be provided by a mobile service team and may be available to people with current housing who are at risk of becoming homeless.

Residential facilities for older adults and/or people with disabilities who are unable to function in an independent living environment because they need assistance with toileting, bathing, dressing, medication management and administration, meals and housekeeping and other activities of daily living, but do not require nursing care on a regular basis. Living options range from state institutions for individuals with the most severe disabilities who require intensive services to settings that enable individuals with disabilities to live with their own families or in their own homes or apartments with supportive services from community-based supported living providers. Alternatives in between include health care facilities for people with a primary need for developmental services in combination with an intermittent need for skilled nursing care; community care facilities (residential care homes or group homes) for people who require varying levels of supervision and assistance in the activities of daily living; assisted living facilities; continuing care retirement communities; life care communities; foster family placements for adults who will benefit from interaction in a family environment; and semi-independent living facilities for individuals with disabilities who need minimal levels of support to live and work in the community. Some of these facilities are licensed by the state.
