Property Line and Fence Laws in Colorado

Of the various types of problems that neighbors have, disputes involving fences are some of the most contentious. One way to deal with these issues is to be proactive and avoid them in the first place. For instance, you can conduct a survey so that you know exactly where your property ends. However, even with careful planning, you can't always avoid conflict and must deal with neighbor disputes when they occur. Ideally, neighbors settle their disagreements informally; but when that fails to resolve the issue, they can look to Colorado's state laws for guidance on property line and fence law matters.

Fence Laws in Colorado

Typically, property disputes involving fences are near the top of the list of heavily litigated cases. An issue that often comes up between neighbors is whether there has been an encroachment of the legal boundary lines by an adjoining owner. Unless the property owners to a fence dispute mutually agree, fences that are located on the actual boundary line belong to both property owners. As such, both are responsible for maintaining the condition of the fence and the costs of any repairs.

The term "fence" can be interpreted broadly and encompasses not only all kinds of traditional fences, but also includes markers, bushes, and trees that can be considered a fence, as they serve as a partition between properties.

Tree Trimming Laws in Colorado

The handling and treatment of trees is another subject matter that causes disputes between neighbors. Under Colorado common law, property owners have the right to cut off roots and branches that extend over their property lines. However, if a person knowingly cuts down or damages a boundary tree, then they can be charged with a misdemeanor.
