A local historic district is applied through the same procedure used to change the zoning of a parcel or parcels. Prior to the district’s adoption by the governing body, an investigation and report (Preservation Plan) must be developed, describing the boundaries of the district as well as the significance of structures, features, and sites within. After a district is established, a certificate of appropriateness (COA) is required before any exterior changes to the property may be made. Local historic districts can be located using the City’s iMaps mapping program: http://gisweb2.durhamnc.gov/durhammaps/developmenttracker/index.html. Regulations must be consistent with North Carolina General Statute 160A- 400.4.
