Fence Regulations in Edison, NJ

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

Retaining Walls

Edison Township requires a New Jersey-licensed professional engineer to design and certify any retaining wall of four feet or greater built to stabilize a steep slope, under Code Section 31-2.7(b)(3). The rule applies wherever new development or land disturbance touches a steep slope, and the wall cannot be used to make the regulated grade appear flatter.

Key details: PE certification threshold: Retaining walls 4 ft or taller on steep slopes. Governing section: Edison Twp. Code § 31-2.7(b)(3). Steep slope defined: 20% grade/10-ft run, or 12% with 5-ft rise. Applies to: Subdivision/site plan land disturbance. Enforcement forum: Superior Court or Municipal Court.

Edison investigates suspected violations of the steep slope standards through its appropriate personnel and pursues a civil action in the Special Civil Part or full Superior Court, or files in Municipal Court under N.J.S.A. 26:3A2-25, per Section 31-2.9. Each section or subsection violated is a separate offense, and each day a violation continues counts as an additional, distinct offense, so uncertified walls or unauthorized slope disturbance can compound quickly.

Material Restrictions

Edison requires an 8-foot board-on-board fence along the full shared property line wherever a nonresidential site plan abuts a residential zone or use.

Key details: Required height: 8 feet. Style: board-on-board. Triggered by: nonresidential site plan near residential. Exception: existing street/rail/utility separation. Governing section: § 37-4.4.

A nonresidential site plan can be denied or conditioned on installing the board-on-board fence, and building without it after approval is a Zoning Code violation subject to a stop-work order.

Height Limits

Edison Township caps residential fences at four feet in the front yard if they block visibility and six feet everywhere else in a residential zone, per Code § 37-4.3(f)(1). Corner lots must keep a 25-foot sight triangle clear of any fence at each street intersection under § 37-4.3(f)(6), and industrial-zone side and rear fences may rise to ten feet.

Key details: Front yard fence, blocking visibility: 4 ft maximum. Residential fence height cap: 6 ft maximum. Industrial side/rear fence: up to 10 ft. Corner lot sight triangle: 25 ft each leg from intersection. Rear fence vs adjoining nonresidential zone: up to 8 ft.

Fences are enforced under the Zoning Chapter's general violations section, § 37-67.5. Any owner, agent, builder or contractor who erects a noncompliant fence is guilty of a violation, and the Zoning Officer may order the condition remedied in writing. Under N.J.S.A. 40:49-5, a Municipal Court judge may impose up to 90 days in the county jail, up to 90 days of community service, or a fine, and each day the fence remains noncompliant is a separate violation.

Fence Permit Requirements

A fence in Edison Township, New Jersey needs a zoning permit before any building permit issues, per Township Code § 37-67.3 and § 37-67.4. A residential fence permit costs $100; a fence on multifamily or nonresidential property costs $300, under the Zoning Permit Application Fee schedule the Township adopted in 2022.

Key details: Residential fence permit fee: $100. Commercial/multifamily fence fee: $300. When required: Before any building permit issues. Plan-change resubmission fee: 50% of original fee. Nonprofit/affordable-housing reduction: 50% off the fee.

A fence built without the required zoning permit is a violation of Chapter 37, enforced by the Zoning Officer under § 37-67.5. Each day the violation continues counts as a separate offense. A Municipal Court judge can fine the owner, builder or contractor, order up to 90 days in the county jail, or impose up to 90 days of community service; a repeat violation within one year draws an added fine of at least $100.

The Bottom Line

Edison'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 Edison is broadly strict or permissive.

These rules come from Edison's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
