Permanent supportive housing is defined as permanent, affordable housing with comprehensive supportive services for people who are chronically homeless and with disabilities or other substantial barriers to housing stability. Permanent supportive housing is an intensive model of housing and services designed to serve chronically homeless individuals and families who cannot retain stable housing without tightly linked support services, and who can not successfully utilize the clinical services they need to stabilize their lives without having housing.

The Corporation for Supportive Housing (CSH) is the national leader in permanent supportive housing. CSH supports the development of  permanent supportive housing in communities throughout the country by providing high-quality advice and development expertise, by making loans and grants to supportive housing sponsors, by strengthening the supportive housing industry, and by reforming public policy to make it easier to create and operate supportive housing.
