The standards below have been adapted from the Secretary of the Interior’s Standards for the Treatment of Historic Properties. These basic principles were created to help preserve the distinctive character of a historic building and its site, while allowing for reasonable change to meet new needs. The Charleston Standards apply to historic buildings of all periods, styles, and types. They are intended to be applied in a reasonable manner, taking into consideration economic and technical feasibility; they are not hard and fast rules, but rather are meant to serve as principles to assist in determining appropriate treatments for historic buildings.
