The Park Service leaves Bodie in an arrested state of decay. They do little to preserve the buildings other than allowing them to become any worse. Probably the biggest challenge is preventing them from falling over. At 8300' elevation the wind can get to blowing pretty hard off the eastern slopes of the High Sierra.
Here you can see examples of supports added to help buildings remain upright.
The lumber mill.
Someday something will be needed for this building as it is listing to the starboard side.
Even and outhouse will get some support if needed.
No matter how little remains of the original structure, the Park Service is there to lend a helping hand, uh...er..board.
