This bill significantly revises federal housing assistance programs by amending the Housing and Community Development Act. It aims to prohibit the provision of financial assistance on a prorated basis to families where not all members have affirmatively established eligibility. Under this legislation, for a family to receive housing aid, all individuals within the household, regardless of age, must be verified as eligible , effectively ending the current practice of prorated assistance for mixed-status families. Additionally, the bill bans the use of federal grant funds for persons who are neither U.S. nationals nor lawfully admitted for permanent residence. It further restricts the Secretary of Housing and Urban Development from providing major grants, such as Community Development Block Grants (CDBG) and HOME Investment Partnerships Program funds, to any state, local government, or entity that fails to cooperate with federal immigration enforcement . This includes jurisdictions that decline detainment requests from Immigration and Customs Enforcement, restrict information sharing, or do not provide advance notice of removable noncitizen releases, thereby targeting so-called "Sanctuary Cities."
