Full Breakdown
Section 40.06.040.E.8 of the Unified Development Code lists "balloons or other air- or gas-filled figures" among prohibited signs in all zoning districts. The Code's definition of "sign" (§ 40.06.020) is written broadly to include any "three-dimensional figure or model" or "device," with no carve-out for seasonal, decorative, or noncommercial displays, so an inflatable Santa, snowman, or similar air-filled lawn figure falls within the same prohibited category as inflatable advertising balloons. This UDC chapter, per its own purpose clause (§ 40.01.010), governs only "the unincorporated areas of New Castle County": it does not reach Wilmington or Newark, both of which administer their own separate municipal codes.
Violations & Fines
Department of Land Use inspects signs and can order removal within 30 days of notice under § 40.06.050.A; if not removed, the County may remove the display itself and bill or pursue enforcement against the property owner.
