Summary
New Castle County caps weeds and grass on undeveloped parcels at 8 inches within 20 feet of any property line when they sit next to a developed parcel, under the county's Property Maintenance Code.
302.4.1 Undeveloped parcels. Weeds and grass on undeveloped parcels adjacent to developed parcels shall be no greater than 8 inches high within 20 feet of any property line. Any parcel shown on a land development plan in any residential zoning district shall be considered a developed parcel if any lot located on the plan has received a certificate of occupancy.

Full Breakdown
Under Section 302.4.1 of the New Castle County Property Maintenance Code, weeds and grass on an undeveloped parcel adjacent to a developed parcel cannot exceed 8 inches in height within 20 feet of the shared property line; a platted lot counts as developed once any lot on the plan has received a certificate of occupancy. Owners of multiple adjacent undeveloped parcels may treat them as one tract. Farms and agricultural land are exempt, as are wooded areas and wildflower meadows kept 10 feet off the line. The Department of Land Use enforces this in unincorporated New Castle County and in municipalities that opt into county property-maintenance enforcement. Wilmington and Newark run their own codes.
Violations & Fines
Enforced by the Department of Land Use through notice and administrative hearings; continuing violations draw penalties under the code's general-penalty provision (§ 1.01.009), plus cost-recovery charges added to the property owner's bill.
