New Castle County fences in residential districts must not exceed 6 feet. Posts and structural elements may extend to 7 feet to account for sloping ground. A 2024 ordinance updated street-yard fence rules.
New Castle County Code (UDC Chapter 40) limits residential fence height to 6 feet for panels and materials, with posts allowed up to 7 feet to accommodate installation on sloping ground. Non-residential fences may be up to 8 feet (9 feet with sloping ground adjustment). Ordinance 24-059 (effective September 3, 2024) updated maximum fencing height for street-yard fences and added requirements for fences in floodplain areas. Fences are generally exempt from permits except for pool barriers and floodplain areas.
Fences exceeding height limits must be modified to comply. Floodplain fences without required permits violate Ch. 40.
