Navigating the Illinois Fence Act: Who Pays for Shared Boundary Fences?

Fences are supposed to make good neighbors, but disagreements over who pays for them often lead to bitter legal disputes. In Illinois, boundary fences are regulated by state law, which dictates exactly how costs, repairs, and responsibilities are shared between adjoining landowners. Whether you live in a rural farming community outside Rockford or a densely populated suburb like Aurora, knowing your rights under the state's statutes is crucial before you start digging post holes.

The Illinois Fence Act Explained

The primary law governing these disputes is the 765 ILCS § 130/3. The act establishes a core rule: when a fence is situated exactly on the boundary line between two properties, both owners are legally responsible for a 'just proportion' of the fence. This means sharing the cost of construction, maintenance, and eventual replacement.

Agricultural vs. Suburban Fence Rules

The Illinois Fence Act was originally drafted with agriculture in mind to keep livestock from wandering. If you live in a rural area near Bloomington or Champaign, the law strictly enforces the shared cost of 'legal fences' (often woven wire or barbed wire) to contain livestock. However, in urban and suburban areas, local municipal zoning codes frequently overlay the state law. In cities, one neighbor cannot force another to split the cost of a highly expensive, decorative privacy fence if a standard chain-link fence would suffice for boundary purposes.

Legal Height Limits and Spite Fences

Before building, you must verify your local city ordinances regarding height. Most residential areas in Illinois restrict backyard fences to 6 feet in height, and front yard fences to 3 or 4 feet. Furthermore, Illinois law does not recognize a cause of action for 'spite fences.' Under the long-standing precedent of Guest v. Reynolds, 68 Ill. 478 (IL Supreme Court 1873), the Illinois Supreme Court rejected the doctrine of ancient lights and held that a property owner has the legal right to build a fence or wall on their land even if it blocks a neighbor's light, air, or view, and such an obstruction is not an actionable nuisance absent an express easement or local zoning violation.

Step-by-Step Process to Force a Neighbor to Split Costs

If your shared boundary fence is rotting, falling over, or completely destroyed, and your neighbor refuses to contribute to the repair, you have a legal path to compel them under Illinois law.

Step 1: Written Notice to the Neighbor

You cannot simply build a new fence and hand your neighbor a bill. You must provide them with a formal, written notice stating that the boundary fence requires repair or erection and requesting they contribute their just proportion. Under 765 ILCS § 130/11, the law requires giving 10 days' written notice for the reparation of an existing fence or 60 days' written notice for the erection of a new division fence. If they ignore or refuse this notice after the required statutory period expires, you can proceed to make or repair the fence at their expense and escalate to recover the costs.

Step 2: Contacting the Township Fence Viewers

Unique to the state, disputes under the 765 ILCS § 130/7 are handled by local officials known as 'Fence Viewers' (usually the township board of trustees). You can submit a request to your local body, such as the City of Bloomington Township Board of Trustees, Bloomington. The Viewers will physically come to the property, examine the fence, and issue a binding written decision regarding how much each neighbor must pay. Their decision carries the weight of a legal judgment.

Step 3: Filing a Lawsuit for Non-Payment

If the neighbor ignores the ruling of the Fence Viewers, or if you live in a municipality that does not utilize Viewers, your attorney will file a civil lawsuit. This involves filing a civil complaint under 735 ILCS § 5/2-601 directly with a court like the Winnebago County Circuit Court, Rockford or the Sangamon County Circuit Court, Springfield to secure a court order for payment.

How Much Does it Cost to Enforce Fence Rules?

Engaging the local Township Fence Viewers is generally inexpensive, often requiring only a nominal administrative fee (under $100). However, if you must hire an attorney to take the neighbor to Circuit Court, you will incur standard hourly legal rates of $250 to $450 per hour. In many fence dispute cases, if the Fence Viewers have already ruled in your favor and the neighbor simply refuses to pay, a judge may force the losing neighbor to cover your court costs.
