The Secretary of the Interior’s Standards are intended to promote responsible preservation practices that help protect our Nation’s irreplaceable cultural resources. Choosing the most appropriate treatment for a building requires careful decision-making about a building’s historical significance as well as its relative importance in history, physical condition, proposed use, and mandated code requirements.
