Fence Regulations in Elgin, IL

Elgin maintains 119 local ordinances across all categories, and 3 of those deal specifically with fence regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where Elgin falls on the strict-to-permissive spectrum compared to other cities.

Retaining Walls

Elgin's amended residential code requires a 36-inch guard on any retaining wall within 2 feet of a walk, path or driveway where the grade change exceeds 30 inches. Walls holding back more than 24 inches of unbalanced fill must be engineered by a licensed structural engineer or architect under Elgin Municipal Code § 16.36.020.

Key details: Guard trigger: grade change over 30 in within 2 ft of walk/drive. Guard height: 36 inches minimum. Baluster spacing: blocks a 21-inch sphere. Engineering trigger: over 24 in of unbalanced fill. Safety factor required: 1.5 against sliding/overturning.

A retaining wall built without the required engineering above the 24-inch trigger, or without the 36-inch guard where the grade/proximity trigger applies, is a building code violation. The city's general penalty under Elgin Municipal Code § 1.20.020 applies: a fine of not less than $50 nor more than $750, with each day the violation continues treated as a separate offense. If work continues after a stop-work order is issued, § 110.4 of the amended building code (§ 16.04.020) makes continued work a separate finable offense.

Fence Permit Requirements

Elgin requires a building permit before any fence is constructed or installed anywhere in the city. Fences must also meet the design standards in Title 19 of the Elgin Municipal Code, and building without a permit exposes the owner to the city's general ordinance-violation penalty.

Key details: Permit required: before any fence construction or installation. Design standards: must follow Title 19 (zoning). Issuing office: community development building division. Adopted: Ord. No. G13-25, 3-26-2025. General fine range: $50-$750 per day, Ch. 1.20.020.

Installing or constructing a fence without first obtaining a building permit is a violation of Elgin Municipal Code § 16.04.040, enforced through §§ 109.3-109.4 of the building code. The city's general penalty under § 1.20.020 applies: a fine of $50 to $750, with each day of the unpermitted fence's existence treated as a separate offense, plus a separate fine if work continues after a stop-work order.

Neighbor Fence Rules

Illinois has no residential fence cost-sharing law. Each property owner is responsible for their own fence. Fences must be on the owner's property. The finished side should face outward.

Key details: Cost Sharing: No IL law requires it. Property Line: Fence must be within yours. Finished Side: Should face outward. IL Farm Law: 765 ILCS 130 (ag only).

Fence on neighboring property: removal may be required.

The Bottom Line

Elgin'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 Elgin is broadly strict or permissive.
