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 Secretary’s Standards for Rehabilitation

The most commonly used standard used by preservationist organizations nationally, “the intent of the Standards is to assist the long-term preservation of a property’s significance through the preservation of historic materials and features. The Standards pertain to historic buildings of all materials, construction types, sizes, and occupancy and encompass the exterior and the interior of historic buildings. The Standards also encompass related landscape features and the building’s site and environment, as well as attached, adjacent, or related new construction.
