Permitting is split between the City of Durham and Durham County, with the City-County Planning Department providing unified planning services for both jurisdictions. The county handles unincorporated areas, while the city manages all permits within its municipal limits. Development is subject to the Durham Unified Development Ordinance, which includes specific watershed protection and floodplain management overlays.
How this fits with the state
The state authority here is NC Licensing Board for General Contractors. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
