This bill establishes a new competitive grant program to support significant improvements within manufactured housing communities. It amends the Housing and Community Development Act of 1974 to create this initiative, which aims to enhance the living conditions and long-term sustainability of these communities. The program will provide financial assistance for a wide range of projects directly benefiting residents, with an emphasis on low- and moderate-income persons . Grants will be awarded to various eligible recipients , including resident-owned communities, local governments, non-profit entities, and Indian Tribes. An eligible manufactured housing community must be affordable to low- and moderate-income persons and either resident-owned or committed to maintaining long-term affordability. Funds can be utilized for critical community infrastructure , housing reconstruction or repair, and activities addressing resident health, safety, and accessibility, such as weatherization and disability access. Additionally, the program supports land acquisition for expansion, planning activities, and essential resident services like relocation assistance and eviction prevention. While grants cannot be used for rehabilitating units built before June 15, 1976, they can fund their replacement with new, compliant homes. The Secretary is mandated to prioritize applications that primarily benefit low- and moderate-income residents and ensure the preservation of long-term housing affordability . The Secretary also has the discretion to set aside funds specifically for Indian Tribes and tribally designated housing entities.
