This bill amends the Housing and Community Development Act of 1974 to establish a new competitive grant program under the Community Development Block Grant (CDBG) framework. The program directs the Secretary of Housing and Urban Development to incentivize states, Indian tribes, and insular areas to adopt policies that enable residents to purchase their manufactured housing communities. This initiative aims to preserve affordable housing and foster resident control over their communities. To qualify for these grants, eligible entities must either implement specific model laws or provide data demonstrating an effective purchase opportunity for residents. The model laws require community owners to give residents and housing finance agencies 60 days' written notice before accepting an offer to sell, detailing the price and terms. If residents, with majority support, present a matching offer within 60 days, the owner must sell to them; otherwise, good faith negotiation is required. An "effective purchase opportunity" is defined as residents receiving notice in at least 80 percent of sales and successfully purchasing the community in at least 1 out of 20 sales over a 1- to 5-year period. Grant funds are designated for specific uses, with at least 25 percent allocated for land and site acquisition and infrastructure improvements for resident-owned communities. The remaining funds can be utilized for other eligible activities under the Community Development Block Grant program. The Secretary may waive certain CDBG requirements to facilitate the program, ensuring core protections like fair housing, nondiscrimination, and labor standards are upheld.
