New Castle County, DE Property Maintenance: Snow & Sidewalk Clearing (2026)

Unlike many larger municipalities, unincorporated New Castle County does not have a clear countywide ordinance requiring property owners to clear snow from public sidewalks adjacent to their property. This is partly because many unincorporated subdivisions lack public sidewalks or have subdivision-maintained walkways. Where sidewalks exist along county roads, NCC Department of Public Works handles minimal plowing of arterial sidewalks and trails. The City of Wilmington, by contrast, enforces Wilmington City Code §42-58 (or equivalent), which requires property owners and occupants to clear snow and ice from adjacent sidewalks within 24 hours after the snowfall ends, with a minimum clear path (typically 36 inches). Failure can result in fines and city contract clearance billed to the owner. The City of Newark, Middletown, and other incorporated places have similar local rules. For unincorporated county residents, practical expectations and common law tort liability (duty of care to invitees) drive most clearing. Delaware state roads (I-95, I-295, Route 1, US-13, US-40) are plowed by DelDOT; local roads by NCC Public Works or municipal DPWs. Elderly and disabled residents in Wilmington may qualify for assistance programs through city human services. Noise ordinance rules apply to snow removal equipment outside normal daytime hours.
