Easements can include a variety of rights granted by a property owner to someone else. They generally arise between owners whose properties are adjacent to each other. Right of way is one of the most common examples of an easement; in these cases, a property owner with no street front is granted the right to use a specific part of a neighbor's land in order to access the road.
