The Subcommittee has jurisdiction over all of GSA's real property activity through the Properly Acl of 1949, the Public Buildings Act of 1959, and the Cooperative Use Act of 1976. These three Acts are now codified as title 40 of the United States Code. The Public Buildings Service (PBS) is responsible for the construction, repair, maintenance, alteralion, and operation of United States courthouses and public buildings of the Federal Government. Additionally, PBS leases privately owned space for Federal use. GSA owns or leases 9,600 assets and maintains an inventory of more than 362 million square feet of workspace. GSA acts as the "landlord" for the federal government, obtaining and managing space to meet the space needs of other federal agencies. GSA, however, isjust one of nine1 federal agencies that, in total, own or manage 93% of federal real property.
