This bill directs the military departments to study the feasibility of building or expanding privately-owned multi-unit housing facilities for military members in high-cost housing areas across the country. The study will also examine whether part of such a housing facility could be used as a military child development center. The military secretaries must submit their findings to Congress within 120 days of the bill's enactment. The bill targets military housing areas where service members receive the highest housing allowances, specifically the top 25 percent of such areas in the continental United States. The legislation aims to address housing shortages and costs for military families while potentially improving access to childcare at military installations.
