This bill creates a new housing assistance program called Family Stability and Opportunity Vouchers designed to help families with young children who are homeless, unstably housed, or living in poverty. The vouchers will be distributed competitively to public housing agencies, which must offer families mobility services to help them move to areas with good schools and quality childcare, though participation is voluntary. The program targets families with children under age 6 or expecting a child within 300 days, and aims to improve outcomes by relocating them to higher-opportunity neighborhoods. The bill authorizes funding for up to 50,000 vouchers per year from fiscal years 2027 through 2032, along with additional funds to cover administrative and support service costs. Housing agencies that receive funding must ensure vouchers are reused for new eligible families when they become available, and the Secretary of Housing and Urban Development has up to two years to distribute initial funding with a 180-day timeline for subsequent years.
