Historic Preservation Standards and Guidelines

To encourage consistent practices, the National Park Service has developed standards and guidelines that guide preservation work at the national, tribal, state, and local levels. In some cases, these standards can be regulatory. The guidelines explain the standards. The flagship of these preservation guideposts is The Secretary of the Interior's Standards and Guidelines for Archeology and Historic Preservation. These standards and guidelines complement federal historic preservation laws.
