(1) The federal government may only own property rights in land for military institutions and government building for performing functions specifically enumerated in the Constitution.
(2) The square footage of any land used for buildings for performing functions specifically enumerated in the Constituion may be no more than nine times the square footage of such buildings and must be contiguous to the land on which such building resides.
(3) The District of Columbia is exempt from the foregoing provisions.
(4) All other property rights held by the federal government are hereby divested to the states.
