Housing Supply Expansion Act

S.1682, the Housing Supply Expansion Act, updates wage determination rules for federal housing projects to streamline processes. It simplifies how prevailing wages are calculated by allowing geographic groupings beyond local areas (Section 2), limits projects to one wage rate based on residential character (Section 3), and creates a working group to review modernizing Davis-Bacon Act requirements (Section 4). The bill directly affects housing developers, contractors, and labor organizations participating in federal housing programs like FHA projects, Native American housing, and public housing (Sections 5-9). Key changes include requiring the Secretary of Labor to improve survey participation and data collection methods for wage determinations, and directing a working group to recommend potential waivers for affordable housing construction. The bill does not directly increase housing supply but aims to reduce administrative barriers in wage rules affecting housing development.
