Raleigh, NC zoning map & districts

Raleigh consolidated its zoning, subdivision, and development regulations into a single Unified Development Ordinance in 2013, administered by the Raleigh Department of City Planning using a base-district-plus-overlay system. "Missing Middle" text changes adopted in 2021 and 2022 stripped out use restrictions and reduced parking minimums in most residential and mixed-use base districts, legalizing duplexes, triplexes, and townhomes without a rezoning in districts that once permitted only detached houses.

Raleigh's zoning map and UDO text are maintained by the Department of City Planning through the city's iMAPS GIS portal, which returns the base district, overlays, and zoning case history for an address.

A published summary is never the authority. The adopted ordinance and the city's official zoning map govern, and both change — verify the district and every standard on your parcel before you rely on it.

How zoning works in Raleigh

Height and frontage standards are layered on through numeric suffixes and overlay districts — including Neighborhood Conservation Overlay Districts (NCOD) — that can tighten a base district's standards for a specific area. Downtown parcels use the DX (Downtown Mixed Use) family, with intensity tiers set by height-district suffixes.
