Durham, NC Zoning Overlays & Bonuses: Downtown Design Guide (2026)

The Downtown Design (DD) District sits inside Article 16 of Durham's joint City-County Unified Development Ordinance and applies only within the Downtown Tier, the area mapped by the Downtown Durham Master Plan and Comprehensive Plan (UDO § 4.5.1). Article 16 focuses regulation on building form -- mass, scale, and the relationship between buildings and the streetscape -- rather than on the underlying land use (§ 16.1.1), and every DD, Compact Design (CD), and Compact Suburban Design (CSD) parcel must also follow every other Article of the UDO unless Article 16 itself states an exemption (§ 16.1.2).

Where a Design District overlaps a Historic District Overlay, Sec. 4.10 standards stack on top. The Planning Department's Durham Design Manual supplies guidance for meeting Article 16, but where the manual and the codified Design District standards conflict, the codified standards control (§ 16.1.2). Ground-floor residential units and overnight-accommodation guest rooms must have a finished floor elevation at least 30 inches above the adjacent street grade, unless the building uses a 10-foot forecourt frontage, sets ground-floor uses back at least 20 feet from the street facade, or the space is a lobby, foyer, or other entry area (§ 16.1.3).

A building holding only one or two dwelling units must also carry a separate primary nonresidential use -- home occupations don't count -- except for buildings in the S2 sub-district of the DD and CD districts and certain single-family/two-family subdivisions in CSD-S2 (§ 16.1.3). Sub-districts run Core, Support-1, and Support-2 in descending development intensity (§ 4.5.4), plus the Ninth Street Pedestrian Business special sub-district. Article 16 violations are enforced the same as any UDO violation, through the Planning Director's notice-and-citation process under §§ 15.1-15.4.
