The "Build Housing with Care Act of 2025" aims to address the dual crises of affordable housing and child care by establishing a competitive grant program. This program, administered by the Secretary of Housing and Urban Development, will fund the design, planning, construction, conversion, and renovation of co-location facilities . A co-location facility is defined as a housing development that includes an eligible child care provider within, on the premises of, or nearby, specifically serving the residents of that housing facility. Eligible entities for these grants include a wide range of organizations such as community development financial institutions , public housing authorities, non-profit housing developers, Indian Tribes, and eligible child care providers. Applicants must certify that the associated child care provider is eligible for Child Care and Development Block Grant (CCDBG) vouchers and commit to not evicting residents due to the project. A business plan for the child care provider, including licensing information and budget, is also required. In awarding grants, the Secretary will prioritize projects that demonstrate the child care provider will operate in a child care desert , a low-income community, or a rural area. Priority is also given to providers designated as Head Start programs or those enrolling at least 10 percent of children from very low-income families, or entities partnering with a community development financial institution. Individual grants can be up to $10,000,000, and funds can be used for various activities related to new or existing co-location facilities, including pre-development and technical assistance. The bill authorizes $100,000,000 annually for fiscal years 2026 through 2031 to carry out the program. The Secretary is mandated to provide technical assistance, publish best practices, and submit annual reports to Congress detailing program implementation, including the number of grants awarded, child care slots created or preserved, and demographic data. Additionally, the bill directs the Government Accountability Office (GAO) to conduct a study and report on child care access for residents of public housing, evaluating existing funding uses, cost impacts, and barriers to establishing child care facilities, along with recommendations for improvement.
