Utility Easements on Property

You may have many utility lines leading to your house for certain services. Some of these may include lines, pipes, dishes, meters, or tanks for:

• Electricity
• Gas
• Propane
• Sewer
• Water
• Telephone
• Internet and cable television
• Satellite television companies
• New utilities as technology changes

If you have any of these, you have an easement because the companies can access your property, for example, to fix a broken water pipe or electric power lines that fell in a storm. As the property owner, you're giving these companies the right to come onto your property to maintain and repair these lines or pipes. You own the land, but they have the right to use your land to access their equipment.

Utility Companies' Rights

Property owners have the right to use the land as they see fit, including the easement area, so long as they're not obstructing the easement itself. For example, if there's a written easement for a company to use a small corridor along your property to access its equipment in the back, you can't build anything on it or obstruct that corridor. If you do, the utility company can remove the obstruction or even destroy it if it interferes with the easement.

That doesn't mean you can't build a fence, or plant shrubs or flowers along the border, so long as they don't interfere with the utility companies' access to their equipment. Remember that your deed permits utility companies to access it whenever needed so that they can take you to court—they can ask the judge for an injunction to stop you from blocking entry onto your property—for violating the easement.
