The U.S. government owns, as of 2012, more than 300,000 buildings, the General Services Administration says.

The GSA, in a recent report, said that three branches of the military, the Army, Air Force and the Navy, own roughly half of the federal government's 306,000 buildings.

In addition, the federal government owns and leases 486,000 structures like parking lots.

The government said in 2012 that about 77,000 of the buildings it owns are underused or unnecessary.
