Wilmington planning commission backs revised R3 duplex rules with porch and orientation incentives

The Wilmington Planning Commission voted unanimously Dec. 3 to recommend a revised amendment to the city's land development code that would allow duplexes on smaller lots in the R3 residential district if builders meet new building‑orientation standards.

Planning Director Linda Painter told the commission the amendment is a scaled, incentive‑based alternative to an earlier applicant proposal that would have eliminated minimum lot‑area requirements for duplexes. Painter said staff reconsidered the original approach after a December 2024 North Carolina statutory change limited municipalities’ ability to decrease development intensity without written consent from affected property owners. "We were really throwing a very wide door open," Painter said, and the revised approach lets the city proceed more incrementally.

Under the approved recommendation (LDC‑31225), lots of 4,000 sq ft or larger — which already may host duplexes — remain unaffected. For lots between about 2,500 and 4,000 sq ft, duplexes would be permitted only if the building meets a set of orientation standards designed to preserve block‑face character: the facade must orient to the primary street, the unit must have a primary entrance facing the street, a front porch at least 8 feet deep and covering roughly 50% of the front facade is required for new construction, and properties inside National Register historic districts would need at least 25% glazing on the front facade. Painter said the 25% glazing standard was limited to national register districts because state statutes constrain regulating numerous building‑design elements for small residential buildings.

The staff recommendation also includes a carve‑out for existing buildings and structures already permitted: porch and glazing requirements would not apply to dwellings that were existing or permitted as of Jan. 6, 2026, to ease conversions of single‑family homes to duplexes. Painter said staff will amend the draft ordinance text to clarify the "existing or permitted as of Jan. 6, 2026" language before forwarding the matter to City Council.

Commissioners focused much of their questioning on how the Design Adjustment Committee (DAC) would handle waiver requests and whether the porch and glazing metrics are overly prescriptive. Painter and other staff explained DAC review is a quasi‑administrative process in which applicants may seek adjustments; unlike the Board of Adjustment, DAC may approve a request based on meeting one of several findings. Commissioners also discussed the practical effect on lots in the downtown R3 area: Painter said there are roughly 1,100 lots of 4,000 sq ft or more (about 10% vacant), and roughly 846 lots under 4,000 sq ft (about 72 vacant) — figures she offered as approximate.

After discussion, Commissioner Collier moved to approve LDC‑31225 "incorporating the amendments made by staff," and Commissioner Pollock seconded. The commission took a roll‑call vote and approved the recommendation unanimously; the chair said the item will be forwarded to the City Council for its consideration in January.

What happens next: City Council will review and act on the Planning Commission's recommendation at a future meeting (staff cited a tentative January council agenda). Staff told commissioners they will monitor implementation and that the ordinance — if adopted by council — could be revisited if unintended impacts arise.

Acknowledging disagreements over details such as porch depth and the DAC process, several commissioners urged that staff brief council on the nuances and consider a follow‑up review after implementation to see whether the incentives are working as intended.
