Summary

City zoning code lets the building inspector order down any fence or wall built mainly to annoy or damage the property next door, regardless of the district or the fence's own height and setback compliance.

Spite fences. No fence or other structure deemed by the building inspector to be designed primarily to cause annoyance or damage to adjoining property shall be permitted.

Full Breakdown

Wilmington's zoning code addresses spite fences separately from its general height and setback rules. Section 48-475(d) lets the building inspector disallow any fence or other structure found to be designed primarily to annoy or damage the property next door, no matter how it is built or how tall it is. The ban applies citywide, in every residence, waterfront and commercial district, and stands apart from the same section's six-foot solid-fence and eight-foot open-fence limits, its building-setback-line rules, and its ban on barbed and razor wire fencing material.

Violations & Fines

Violating Chapter 48, including the spite-fence ban, is a misdemeanor: $250 to $1,000 for a first offense, up to $2,500 for a second, and up to $5,000 or a year in jail for repeat offenses.

Frequently Asked Questions

What counts as a spite fence in Wilmington?
Any fence or structure the building inspector finds was designed mainly to annoy or damage the neighboring property, regardless of height, material, or whether it otherwise meets the zoning code's fence rules.
Does the spite-fence ban replace Wilmington's normal fence height limits?
No. It applies on top of the separate rules in Sec. 48-475 that cap solid fences at six feet and open fences at eight feet in residence, waterfront, and commercial districts.
