S.D. Codified Laws § 1-19B-42
After the designation of an historic district, no exterior portion of any building or other structure (including walls, fences, light fixtures, steps, and pavement, or other appurtenant features) nor above-ground utility structure nor any type of outdoor advertising sign may be erected, altered, restored, moved, or demolished within such district until after an application for a certificate of appropriateness as to exterior features has been submitted to and approved by the Historic District Commission. The municipality shall require such a certificate to be issued by the commission prior to the issuance of a building permit or other permit granted for purposes of constructing or altering structures. A certificate of appropriateness is required whether or not a building permit is required.
