Advisory Council Requests Comments on Secretary’s Standards

June 28, 2023

The Advisory Council on Historic Preservation is inviting public feedback regarding application and interpretation of the Secretary of the Interior’s Standards for the Treatment of Historic Properties (Secretary’s Standards) and associated guidelines.

The Department of the Interior sets out four treatments in the Secretary’s Standards: preservation, rehabilitation, restoration, and reconstruction. Each of the four Standards differs slightly in its articulation and in the expected results.

Comments must be submitted in writing by 5 p.m. on July 20, 2023, by emailing

Major themes and issues that emerge from the comments received will be shared with the Department of the Interior, which is a member of the Advisory Council on Historic Preservation, and the National Park Service, which is tasked with promulgating regulations and issuing guidance related to the Secretary’s Standards.
