Permanent Supportive Housing — usually shortened to PSH — is the model that has done more than any other to change how the US thinks about housing for adults with schizophrenia and other serious mental illness. It pairs a regular apartment lease with voluntary support services, treats housing as a foundation rather than a reward, and has built up a substantial evidence base over the last twenty-five years. This guide explains what PSH is, how it works, who pays, and how to access it.
Permanent Supportive Housing combines a long-term affordable apartment lease — held by the tenant — with voluntary, individualised support services, and is the best-evidenced housing model for ending homelessness and supporting recovery in people with serious mental illness.
The two parts of PSH
PSH has two essential ingredients, and the model only works when both are present.
1. Permanent, affordable housing
The tenant signs a real lease. They have tenant rights under state landlord-tenant law. The lease is not contingent on participation in treatment. Rent is typically capped at 30% of the tenant's income (matching the HUD definition of affordability), with the rest covered by a subsidy.
2. Voluntary support services
Support services are made available, not required. Typical offerings include case management, help with benefits, help with medication, connections to mental-health and primary-care providers, and help with daily-living skills. Services are tenant-driven: the tenant decides what they want, when, and how often.
Two PSH models: scattered-site and single-site
Scattered-site PSH uses tenant-based rental assistance (typically a Section 8 voucher) to rent ordinary apartments throughout the community. The tenant lives wherever they want among landlords willing to accept the voucher; case-management staff visit. This is the dominant model for people with schizophrenia.
Single-site PSH uses a building (or part of one) where multiple PSH tenants live and where on-site staff are available. Useful for people who benefit from on-site support, but less common today than scattered-site.
The evidence base
PSH is one of the most rigorously studied housing models in mental health. The findings, summarised by SAMHSA's Permanent Supportive Housing toolkit, the HUD Office of Policy Development and Research, and many academic studies, include:
- Strong housing retention. Many PSH programmes achieve 80% or higher one-year housing retention among formerly homeless tenants with serious mental illness.
- Reduced hospital and emergency-room use. Several studies find 30% to 60% reductions in psychiatric hospital days for tenants in PSH.
- Reduced use of jails and shelters. Particularly in PSH programmes that target chronically homeless adults with serious mental illness.
- Cost offsets. Reductions in expensive crisis services often partially or fully offset the cost of the housing subsidy.
The federal interagency US Interagency Council on Homelessness has used these findings to make PSH the recommended response to chronic homelessness for adults with serious disabilities.
PSH versus Housing First
PSH and Housing First are related but not identical. Housing First is a philosophy: provide housing without preconditions like sobriety or treatment compliance. PSH is a programme model: long-term affordable housing plus voluntary services. Most modern PSH operates on Housing First principles, but a programme can in theory be one without the other. The combination is now standard in most federally funded PSH.
Who PSH is designed for
HUD's Continuum of Care PSH programme prioritises people who:
- Are experiencing chronic homelessness (long-term or repeated homelessness)
- Have a documented disability — often serious mental illness, including schizophrenia
- Have not been well-served by short-term or transitional housing
Other PSH funding streams have different eligibility — state mental health authority programmes often serve people with serious mental illness regardless of homelessness status, and HUD's Section 811 Project Rental Assistance programme creates PSH units in mainstream affordable housing developments specifically for adults with disabilities.
Who pays for PSH
PSH is generally split between funding for the housing portion and funding for the services portion.
Housing
- HUD Continuum of Care PSH programme
- HUD-VASH for veterans
- Section 8 housing choice vouchers (HCV)
- Section 811 PRA
- State and local affordable housing programmes
Services
- Medicaid — increasingly funds tenancy supports through 1915(i), 1915(c), and Section 1115 waivers
- State mental health authority funding
- SAMHSA grants
- HUD CoC service dollars
- Local foundation and city funding
How to access PSH
- Connect with a Coordinated Entry system. Most US communities have a single point of entry for homeless services that triages applicants and refers them to PSH. The local Continuum of Care lead agency runs it.
- Talk to your community mental health centre. Many CMHCs operate or partner with PSH programmes for clients with serious mental illness, and may not require homelessness status.
- Apply for the Section 8 housing choice voucher at the local Public Housing Authority. Wait lists are long, but the voucher is the cornerstone of scattered-site PSH.
- For veterans, ask about HUD-VASH through the local VA.
- For people with disabilities, ask about Section 811 — your state housing finance agency or local independent living centre is a starting point.
- Use 211 to be connected with local PSH and housing resources.
What it actually feels like
For tenants who have been through institutional or shelter settings, PSH often feels different in ways that matter. Having a key to your own door, being able to invite a friend over, choosing what to eat — these are the small returns of autonomy that institutional settings strip away. The case manager is a resource, not a supervisor. The lease is yours; the door locks from the inside.
For some tenants, the transition is hard. Living alone after years in supervised settings can be lonely, and developing the daily-living rhythms takes time. A good PSH programme expects this and meets it with support, not pressure.
People with very acute symptoms, severe medical needs requiring 24-hour care, or extreme isolation that endangers them may need a higher level of support — at least temporarily. PSH is designed to be flexible and to meet most needs, but it is not a substitute for hospitalisation or skilled nursing care.
The bigger picture
For decades the US response to housing instability among people with serious mental illness was a patchwork of shelters, jails, hospitals, and board-and-care homes. PSH represents a different bet: that with a real apartment and the right support, most adults with schizophrenia can live successfully in the community. The evidence has largely vindicated that bet. The barrier now is scale — there are far more adults who would benefit from PSH than there are units available, and the wait lists in most cities are long.
