Property Line and Fence Laws in Illinois
A drive through rural Illinois will reveal many neighborhoods without perimeter fences. You may wonder whether there are laws prohibiting fences, or maybe all the neighbors just good friends? The answer is likely a mixture of both. However, fences are commonplace in most urban areas and, unfortunately, so are disputes over fences and property lines.

Illinois Fence Law Basics
Most fence-related issues are about the appearance, location, and height of the fence, and whether a homeowner overstepped the legal property line of an adjoining property. Illinois' Fence Act was drafted to clarify issues common to those with large tracks of farmland or living in rural, unincorporated regions. A legal fence is defined as one that will sufficiently contain livestock on the land.
However, there are portions of the state's Fence Act that can impact those in residential neighborhoods. For example, in counties with less than one million residents and not within the corporate limits of any city in such county, when one land owner wants to fence their property, each owner of adjoining land must pay for and maintain the fence even when they do not want the fence installed.
Neighbors' Responsibilities for a Common Fence
Illinois state law and local ordinances place the responsibility for maintenance of a boundary fence separating two properties on the owners that use the fence. Consequently, when a fence needs repair, both property owners must share the cost. If one party refuses to cooperate, the other party can do any of the following:
- Write a letter to the neighbor explaining the problem with the fence
- Request a "fence viewer" examine the fence and make a recommendation of whether the fence needs repair or whether the amount requested for repair is reasonable
- Go to mediation
- Sue the neighbor for reimbursement
Tree Trimming Along Property Lines
Trees and shrubs can add value to your home, but they can also cause problems between neighbors. For example, tree branches can hang over a fence, dropping leaves in the neighbor's pool. Trees roots can also cause damage to sidewalks and nearby structures. How you handle a problematic tree depends on where it's located.
- Branches that Overhang into your Property: Generally, you may cut branches so long as it does not damage the health or structure of a tree.
- Tree Roots: You may not remove tree roots that encroach onto your property. Once the roots cause damage to your property, you can sue for compensation, and probably make your neighbor remove them.
- Trees on Your Property Line: Illinois case law states that if any part of a tree trunk crosses the property line, it's a jointly owned tree. A neighbor can stop the other from removing the tree.
- Damage Caused by Your Trees: You have a duty to take reasonable steps to prevent your tree from harming your neighbors.
Spite Fences in Illinois
When a fence is built by a property owner whose primary motivation is spiteful or malicious it is commonly referred to as a spite fence. Although there is not a state spite fence law, such cases can be addressed under nuisance law principles. A balancing test will be applied to weigh the negative effect on the aggrieved landowner's use and enjoyment of their property against the value of the structure to the fence owner. Such structure may also be addressed as being in violation of local ordinances, zoning codes, or homeowner's association regulations.
Fences and Local Ordinances
Your home may be your castle, but there is a growing list of agencies that have a say in what you can and cannot do to fence your property. In addition to the State of Illinois, your right to have a fence and its general appearance are impacted by county and city laws, utility and wildlife easements, and any applicable homeowner association rules. Plus, you likely will need a building permit to construct or replace a fence. Cities with fence ordinances include:
