The No Cages in the Everglades Act prohibits the Department of Homeland Security and U.S. Immigration and Customs Enforcement from spending any federal funds to plan, build, lease, operate, or maintain an immigration detention facility within or near the Everglades ecosystem in Florida. The bill affects immigration detention operations in southern Florida's wetland areas, including Everglades National Park and surrounding regions. Additionally, the legislation grants Members of Congress and designated staff the right to conduct announced or unannounced inspections of all immigration detention facilities operated by DHS, with no restrictions based on contracts or agreements between federal and state or local governments. Within 90 days of enactment, the DHS Inspector General must submit an independent report to Congress evaluating the facility's compliance with federal detention standards, accounting for funds spent, assessing environmental and natural disaster risks, and documenting complaints from detained individuals. The bill does not specify new funding amounts but instead restricts how existing DHS appropriations can be used regarding Everglades detention facilities.
