The purpose of this legislation, known as the "Build Homes, Not Hate Act of 2026," is to address homelessness in the United States by establishing a grant program through the Federal Emergency Management Agency (FEMA). The goal is to provide funding for creating housing units and offering various support services to individuals and families who are experiencing homelessness or are at risk of becoming homeless. Key provisions of the legislation include a requirement for FEMA to set up a grant program within a year of the law's enactment.
