Fence Regulations in Naperville, IL

If you live in Naperville or are thinking about moving there, fence regulations are one of those things you probably won't think about until they affect you directly. Naperville has 4 specific rules on the books covering different aspects of fence regulations, and some of them might surprise you.

Height Limits

Naperville caps residential fences at 3 feet in front yards, 6 feet elsewhere, and 9 feet along arterial roads or non-residential boundaries, plus a 30-foot corner sight triangle.

Key details: Governing section: Naperville Municipal Code § 6-2-12. Front yard max: 3 feet (4 feet if open). Side/rear yard max: 6 feet. Arterial/non-res boundary max: 9 feet. Corner sight triangle: 30 feet, § 6-2-13.

Fences that exceed the district height limit or block the corner sight triangle are zoning violations; the City can require the owner to lower, relocate, or remove the fence.

Material Restrictions

Along Hobson Road, Naperville limits fences to aluminum, wrought iron, PVC, split rail, or three-board horse-fence styles: board-on-board and chain-link are barred outright to preserve the road's rural look, with a six-foot height cap.

Key details: Banned materials: board-on-board, chain-link. Allowed materials: aluminum, wrought iron, PVC, split rail, three-board. Max height: 6 feet along Hobson Road. Fence type required: open fence per Section 6-1-6.

Building an unpermitted board-on-board or chain-link fence along Hobson Road is a code violation; the Zoning Administrator can require removal or replacement with a compliant open-style fence.

Fence Permit Requirements

Any fence in Naperville taller than three feet needs a City permit before it goes up, per Section 6-2-12:1.11 of the Zoning Title. The permit costs eighty-eight dollars under the standard residential fee schedule and applies City-wide, in residence, business, and industrial districts alike.

Key details: Permit trigger: Fences over 3 feet require a City permit. Governing section: Naperville Municipal Code § 6-2-12:1.11. Permit fee: $88.00, per Subsection 1-9H-1.3.7. Max height, business/industrial yard: 15 feet in interior side or rear yard. Max height near arterials: 9 feet along nonresidential or arterial line.

Erecting a fence over three feet without the required permit, or building one that violates the district's height or placement standards, is enforced as a Zoning Title violation under Section 6-3-10. The Zoning Administrator sends written notice to the property owner of record, who has fourteen days to fix or remove the fence; a conviction carries a fine of up to five hundred dollars, with each day the unpermitted fence stays up counted as a separate offense.

Neighbor Fence Rules

Naperville requires the finished side of all fences to face away from the property on which the fence is installed (facing the neighbor). Fences along rear property lines abutting public right-of-way must include access gates for maintenance.

Key details: Finished Side: Must face outward. Access Gates: Required at right-of-way. Property Line: May build to the line. Cost Sharing: Not required by law.

Installing a fence with the finished side facing inward: code enforcement violation requiring correction. Missing required access gates: violation notice. Building past the property line: potential civil liability plus code violation.

The Bottom Line

Naperville's fence regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Naperville is broadly strict or permissive.
