Home businesses in New Castle County residential zones may use only a small nameplate sign. Commercial signage is not permitted in residential zoning districts under UDC Chapter 40.
New Castle County's UDC Chapter 40 restricts signage in residential districts. A home occupation may have a small identification sign (typically 1 square foot or less). Illuminated commercial signs, pole signs, or any signage that alters the residential character of the property are not permitted. This signage rule under New Castle County's home business ordinances applies to unincorporated areas of New Castle County. For current statutory text, amendments, enforcement procedures, fines, appeal options, and any exemptions that may apply to your situation, contact New Castle County code enforcement directly or consult the official Delaware municipal code library. Ordinances change periodically; always verify with local staff before relying on summary information.
Unauthorized commercial signage in residential areas is subject to code enforcement and removal orders.
