MOSSA Act

The MOSSA Act (HR 4878) directs federal agencies to prioritize funding for local governments enforcing laws against public drug use, camping, and loitering, while requiring homelessness programs to link participants with mental health/substance use treatment as a condition of aid. It mandates that federal grant programs for homelessness services end support for "housing first" approaches and "harm reduction" initiatives, instead requiring evidence-based treatment programs and stricter accountability for service providers. The bill also directs agencies to address sex offenders in homeless programs by restricting their housing with children and to review funding recipients operating drug injection sites for legal violations. These provisions collectively shift federal funding toward enforcement-focused and treatment-oriented homelessness strategies, affecting state/local governments, homeless service providers, and individuals accessing federal housing assistance.
