Housing Access Improvement Act

This bill increases the cap on project-based housing assistance units from 20% to 30% of a public housing agency's inventory under the Housing Act of 1937. It specifically allows agencies to use these units for homeless individuals and families, requiring Secretary approval for additional units beyond the standard limit. The Secretary of Housing and Urban Development must issue implementing rules within 90 days of enactment, with the changes taking effect in the first fiscal year after the bill passes. The legislation directly affects public housing agencies managing federally assisted housing, expanding their capacity to serve homeless populations through modified funding rules.
