Easement rights for utilities include the ability for the utility company to gain access to a landowner's land in order to repair and maintain any utility lines or poles that cross the property, explains SF Gate. Property owners can still reasonably use the land, and the owner pays the taxes.
Utility companies have the right to erect poles and run utility lines on the land for which an easement is granted, states SF Gate. The property owner cannot interfere with the rights and usage granted to the utility company. The property owner cannot built a permanent structure on the part of the land covered by the easement.
Some utility companies do build structures on the property the easement runs through, notes SF Gate. If a property owner would like to build a structure on the land the easement runs through, he needs to obtain permission from the utility company that holds the easement. Easements don't usually come with an expiration date; they instead "run with the land." This means that the easement is automatically transferred when the property exchanges hands, so the utility company still has the rights and usage even when the property is sold to a new owner.
