To encourage local government reform of zoning and permitting to enhance housing affordability and economic growth, and for other purposes.

HR 10171 creates a $10 billion grant program to incentivize local governments to reform restrictive zoning and permitting practices that limit housing development. Local governments that implement specific reforms - such as increasing housing supply, reducing barriers to building affordable housing, and expediting permitting processes - can receive funding for infrastructure improvements, technical assistance, and community engagement related to housing development. The bill also includes additional provisions to support prefabricated housing construction and establish a national building code for affordable housing, with the goal of increasing housing supply and affordability by removing regulatory barriers to development. This bill directly affects cities, counties, and other local governments that choose to participate in the grant program.
