The Historic Preservation Planning Unit is a part of the City’s Comprehensive and Long-Range Planning Division. The unit facilitates several city processes. These include Certificates of Appropriateness (COA), local landmark designation, and rezonings in local historic areas. Staff provides design review services to local historic properties. The unit also staffs the Raleigh Historic Development Commission (RHDC).
The RHDC serves to identify, preserve, protect, and promote Raleigh's historic resources. The RHDC inventories properties important to Raleigh’s history and issues COAs. They hold and attend special events about historic places. The commission also works with decision-makers to support historic properties in the city.
