Installing a new fence can improve privacy and property value. However, most counties require a permit if the fence exceeds 6 feet in height or is located in the front yard.
Set by local rules
Do you need a permit for Fence Installation in New Castle County?
In Delaware, there is no single statewide rule for a Fence Installation; whether you need a permit is decided locally in New Castle County.
Fences are governed mainly by local zoning, not a statewide building permit. Cities set height limits (commonly 3-4 ft in front yards and 6 ft in back and side yards), setbacks, and corner sight-line rules, and many require a zoning permit for any fence. Most jurisdictions exempt fences up to 7 ft from a building permit (IRC R105.2) and require one above that. Replacing a fence at the same height, material, and location usually needs no permit; a fence used as a pool barrier always does. Because Delaware leaves this to local jurisdictions, the reliable answer comes from New Castle County Permit. Zoning setbacks apply either way.
