Permanent Supportive Housing

What Is Permanent Supportive Housing?

Permanent supportive housing (PSH) combines a long-term home with support services. Under HUD’s Continuum of Care rules, it is “permanent housing in which supportive services are provided to assist homeless persons with a disability to live independently” (24 CFR 578.3).

“Permanent” means the resident holds a renewable lease of at least one year that can be ended only for cause, with no set limit on how long someone can stay. That sets PSH apart from time-limited shelters and transitional housing, and from short- to medium-term rapid rehousing.

How Permanent Supportive Housing Works

PSH has two parts:

• Housing. Some PSH is single-site, meaning a building is dedicated to supportive housing and often has staff on site. Other PSH is scattered-site, meaning apartments in ordinary buildings, with rent paid through tenant-based rental assistance or project-based vouchers. Tenants generally pay about 30% of their income toward rent.
• Services. These include case management, mental health and substance use treatment, and help with benefits and daily living. In programs that follow Housing First, services are offered but not required.

Funding is layered. Building costs may come from the Low-Income Housing Tax Credit. Rent support may come from vouchers or HUD’s Continuum of Care Program. The National Academies note that Medicaid can cover some housing-related services but not rent or construction costs. HUD has historically given priority for PSH to people experiencing chronic homelessness.

What the Evidence Shows

In 2018, the National Academies of Sciences, Engineering, and Medicine reviewed the research. They found that, in studies lasting one to two years, PSH keeps most people who had been chronically homeless stably housed. They found no substantial published evidence that it improves health outcomes (except for people with HIV/AIDS) or reduces health care costs. The committee cautioned against expecting net savings, except possibly among heavy users of emergency services.

Criticisms and Policy Debate

PSH is expensive to build and operate, and the National Academies report describes a substantial unmet need for it. Because residents can stay indefinitely, units open up slowly. Critics argue that programs should put more weight on treatment and on helping residents move on to other housing.

Federal policy shifted sharply in 2025. A Continuum of Care funding notice that HUD issued in November 2025 would have capped permanent housing at 30% of funds. HUD withdrew it in December 2025 after two lawsuits. The FY 2026 notice, released in June 2026, instead set aside $1.3 billion with priority for transitional housing and supportive services projects. On August 7, 2026, a federal judge ruled that the set-aside was unlawful. On September 16, 2026, an appeals court let HUD proceed while it considers the appeal, and HUD set an application deadline of September 30, 2026.
