This bill requires the relocation of certain nonessential federal administrative office space from jurisdictions designated as "sanctuary jurisdictions." Within 30 days of enactment, the General Services Administration (GSA) , in coordination with other agencies, must identify all such "covered office space" belonging to "covered Federal agencies." These agencies, which specifically exclude the Department of Homeland Security, must then submit relocation plans within 60 days and complete the move within 90 days of the bill's enactment. Furthermore, the legislation prohibits any covered Federal agency from establishing, acquiring, leasing, or renewing office space in a sanctuary jurisdiction, or using federal funds for such purposes. A "sanctuary jurisdiction" is defined as one that restricts information sharing on immigration status or compliance with lawful Department of Homeland Security detainer requests. The GSA Administrator is also required to submit a report to Congress within one year detailing the identified offices, their relocation status, and associated costs or savings.
