Summary
Wilmington caps on-premises window signs at 10 percent of a building's ground-floor glassed window area citywide, rising to 50 percent inside the Central Business District and CBD-Historic District Overlay. Sec. 18-573(c) restricts these signs to first-floor windows only, permits interior neon, and bars any signage that blocks visibility into or out of the glass.
(c)On-premises window signs.(1)Any principal building may install on-premises window signs provided:a.The area of such signs shall not exceed an aggregate area equal to ten (10) percent of the total ground floor glassed window area of the building. In the CBD and CBD-HDO, the area of such signs shall not exceed an aggregate area equal to fifty (50) percent of the total ground floor glassed window area of the building.b.Such signs, if located inside the window, may be neon signs.c.Such signs shall only be located on first floor windows.d.The signs do not prohibit visibility into and out of the window.
Full Breakdown
Sec. 18-573(c) of the Land Development Code governs on-premises window signs within the Central Business District (CBD), CBD-Historic District Overlay (CBD-HDO), Historic District-Mixed Use (HD-MU) and Main Street Mixed Use (MSMU) District, the 1945 corporate limits core. Outside the CBD and CBD-HDO the aggregate window-sign area may not exceed 10 percent of the ground-floor glassed window area of the building; inside the CBD and CBD-HDO that ceiling rises to 50 percent, reflecting the denser storefront character of the historic downtown core. Every window sign under this section must sit on a first-floor window, glass above the ground floor cannot carry signage, and no sign may block the public's sightline into or out of the display glass.
Neon lettering is expressly allowed as long as it is mounted inside the glass. Wilmington repeats a parallel but separate cap in Sec. 18-579(f) for the Commercial (CB), Regional Business (RB), Community Shopping (CS) and Office and Institutional (O&I) districts: window signage there is likewise held to 10 percent of the ground-floor glassed window area, interior neon is again permitted, and any window sign above the second floor of an occupancy is flatly prohibited. Both provisions sit inside Article 12, Division II, which regulates on-premises signs by district, and both require the same city sign permit that covers the rest of the sign article.
Violations & Fines
Sec. 18-599 doubles the standard sign permit fee for any sign, including a window sign, installed before a permit is issued, and that penalty applies on top of any other requirement in the chapter. Window signs exceeding the 10 or 50 percent glass-area cap, or placed above the permitted floor, are subject to removal by the city manager as a code violation; unpermitted or oversized signage can trigger further enforcement tied to the property's sign permit history.
