Summary

Durham's Downtown Design (DD) District regulates building form, not just use, across the city's Downtown Tier under UDO Article 16. Ground-floor residential space must sit at least 30 inches above street grade, buildings with only one or two dwelling units generally need a separate nonresidential use, and the city's Durham Design Manual yields whenever it conflicts with the UDO's own codified Design District standards.

Design District standards shall be established to regulate the physical form of specific areas within the community... Standards within this Article shall apply to any property with a Downtown Design District (DD), Compact Design District (CD), or Compact Suburban Design District (CSD) zoning designation and applicable sub-district zoning designations. The DD zoning district and sub-districts shall only be permitted in the Downtown Tier... The Durham Design Manual shall be used to provide guidance in complying with applicable Design District standards. Where there is a conflict between the manual and Design District standards, the Design District standards shall apply.

Violations & Fines

Building without meeting Article 16 form standards is a UDO violation (§ 15.1.2). The Planning Director issues written notice; an unresolved violation draws a $500 civil penalty per citation under § 15.4.2, due within 15 days, with an added daily penalty if the violation continues. The Director can withhold or revoke permits, order a stop-work order under NCGS § 160D-404, or seek an injunction in Superior Court. Appeals go to the Board of Adjustment within 30 days of the notice (§ 15.2.2).

Frequently Asked Questions

What is the Downtown Design (DD) District?

It's a form-based zoning district under UDO Article 16 that regulates building mass, scale, and street relationship rather than use, and it applies only within Durham's Downtown Tier as defined by the Downtown Durham Master Plan (§ 4.5.1). Sub-districts -- Core, Support-1, and Support-2 -- set descending intensity levels, with Core allowing the densest development (§ 4.5.4).

Does the Durham Design Manual carry legal weight?

The Design Manual provides guidance for complying with Article 16, but it isn't the final word -- where the manual conflicts with the codified Design District standards, the UDO's own standards control (§ 16.1.2). Treat the manual as interpretive help, not a substitute for the ordinance text.

Do ground-floor apartments have height requirements above the sidewalk?

Yes. Ground-floor residential units and overnight-accommodation guest rooms must sit at least 30 inches above the adjacent street grade, unless the building uses a 10-foot forecourt frontage, places ground-floor uses 20 feet back from the street facade, or the space is a lobby, foyer, or other entry area (§ 16.1.3).

What happens if my downtown project doesn't meet Article 16 standards?

The Planning Director issues a notice of violation; if you don't fix it, expect a $500 civil penalty per citation, a possible stop-work order, and withheld or revoked permits until you comply, with daily penalties for a continuing violation (§§ 15.2-15.4).
