Wilmington's Zoning Code (Chapter 48) establishes residential, commercial, mixed-use, and special-purpose districts, with overlay zones for historic districts, the Riverfront, and waterfront industrial areas governing density and use.
Wilmington City Code Chapter 48 contains the comprehensive zoning ordinance, dividing the city into districts including R-1 single-family, R-3 row-house, R-5A multifamily, C-1 through C-5 commercial, M industrial, and W waterfront. Overlay districts include historic preservation areas (Brandywine, West Side, Quaker Hill) and the Riverfront Wilmington redevelopment zone reshaped during the 1990s-2010s. Zoning controls permitted uses, density, height, setbacks, and parking. Variances and special-use permits go to the Board of Adjustment. Major changes require Planning Commission and Council action. Property owners check zoning before renovations, additions, or business uses.
Operating a non-permitted use, building outside setbacks, or exceeding height limits can trigger zoning citations, stop-work orders, and required removal or amendment.
