Preservation
This standard focuses on sustaining the existing form, integrity, and materials of a historic property.

The property should be protected and stabilized, and the focus is on continual maintenance and repair

limited and sensitive code-required upgrading is allowed.
Rehabilitation
This standard makes a new compatible use possible on a historic property through repair, alterations, and additions while preserving historic features.
Restoration
This standard is used when a historic property is being made to look as it did in a particular time period by removing added features and reconstructing missing features from that time period.

Limited and sensitive code-required upgrades are allowed.
Reconstruction
This standard is used for new construction in a historic site that is meant to replicate a structure that used to be there.
Eugène Emmanuel Viollet-Le-Duc
Considered the first restoration architect. Developed methods and technologies for building preservation. Believed buildings should be restored to what they 'should have been' which is now frowned upon.
Paul Léon
Felt that buildings must remain true to the past, be preserved as they are, and that to embellish a historical building is 'deceitful.'
John Ruskin
Did not believe significant buildings should be restored. Building should be built to last forever and the beauty of age should remain intact.
