Illinois law regarding tree maintenance generally follows a “self-help” doctrine. This means property owners are responsible for trimming tree branches and roots that encroach onto their property, regardless of where the tree trunk is located. They may do so up to the property line. Permission is not required from the tree’s owner, but the trimming must be done reasonably and cannot harm the overall health of the tree. For example, a homeowner can cut back branches that overhang their driveway, but they cannot cut down the entire tree simply because it is located on a neighbor’s property. Damage caused by improperly trimmed trees, however, becomes the responsibility of the person who did the trimming.
Clear property lines and well-maintained trees contribute to positive neighborly relationships and enhance property values. Understanding tree maintenance responsibilities helps prevent disputes and ensures the safety and aesthetic appeal of both private and public spaces. Historically, legal frameworks regarding tree management have evolved from common law principles to reflect the changing landscape of land ownership and urban development. This evolution underscores the importance of clarifying responsibilities to avoid conflicts and promote responsible land stewardship.
