This bill, titled the "Yes in God's Backyard Act," aims to significantly increase the supply of affordable rental housing by leveraging properties owned by faith-based organizations and institutions of higher education. It directs the Secretary to establish a technical assistance program designed to help these entities, alongside local governments, understand and implement strategies for developing and preserving affordable rental housing on their excess land. The program offers resources covering federal assistance, best practices for housing development and preservation, and guidance on removing regulatory barriers to construction. The technical assistance specifically focuses on creating housing for diverse populations, including households at or below 60 percent of the area median income, individuals experiencing or at risk of homelessness, and other special needs groups. Furthermore, the bill establishes a competitive Challenge Grant program for eligible state and local governments. These grants are awarded to applicants that demonstrate existing policies effectively remove barriers to affordable rental housing development on properties owned by faith-based organizations and institutions of higher education, with funds supporting policy assessment, outreach, and direct project financing.
