The Preventing Youth Homelessness Demonstration Act of 2026 aims to provide financial support to organizations dedicated to preventing youth homelessness, particularly for those at risk. The primary goal is to implement effective strategies that help young people, especially those transitioning from systems like foster care or juvenile justice, avoid homelessness. The Act establishes a grant program managed by the Secretary of Health and Human Services, which will award funds to eligible entities such as state agencies, local governments, and educational organizations.
