The most common issues we find with overhead powerlines during home inspections are trees rubbing up against them and exposed connectors that present an immediate shock or electrocution hazard. When we find either one of these conditions, we recommend repair. The question that always follows is “Who’s responsible for that?”
According to Xcel Energy, tree branches in contact with the overhead powerlines between the pole and house are the responsibility of the homeowner. Of course, this is only fair. Tree maintenance should be the responsibility of the homeowner, not the power company. Before trimming trees around overhead powerlines, you should contact the power company to have your service temporarily disconnected.
