The Workforce Housing Development Act would establish a competitive grant program at the Department of Housing and Urban Development to help build, preserve, or rehabilitate affordable homes for working families in areas facing housing shortages. Eligible applicants include state and local governments, nonprofit housing developers, public housing agencies, and community development organizations that would use grants to create workforce housing units affordable to households earning up to 100 percent of their area's median income, with homes remaining affordable for at least five years after purchase. The program prioritizes areas where housing prices are rising, affordable unit supplies are declining, or employers struggle to recruit workers due to lack of affordable housing. The bill establishes a dedicated Workforce Housing Development Fund and authorizes unspecified funding levels for fiscal year 2024 and beyond, with the HUD Secretary required to report annually to Congress on grant recipients, the number of homes created or rehabilitated, and details about homebuyers including first-time buyers.
