A property owner may apply for historic landmark designation. A historic properties survey serves as a guide for determining eligible properties for designation. The staff prepares a report attesting to the significance of the structure, which is reviewed by the State Historic Preservation Office (SHPO), the Historic Preservation Commission, and the governing body, the latter of which makes the final determination. The landmark is adopted by an Ordinance of Designation which must describe the property, list its owners, name key elements of its historical significance, affirm the waiting period required (up to 365 days) prior to a demolition, and note that a Certificate of Appropriateness is required for any exterior changes to the property. Local historic landmarks can be located using the City’s iMaps program: http://gisweb2.durhamnc.gov/durhammaps/developmenttracker/index.html.
