The purpose of this legislation is to streamline the process for disposing of certain federal buildings that are no longer in use. It aims to allow the federal government to sell or lease these properties, which can help reduce costs and potentially generate revenue. The act is officially titled the "Disposing of Inactive Structures and Properties by Offering for Sale And Lease Act," or the "DISPOSAL Act." Key provisions of the act include the requirement for the Administrator of General Services to dispose of specific federal buildings in Washington, D.C.
