What's different about generator installation in Seattle
Standby generators with automatic transfer switches are also installed, especially where someone in the home relies on medical equipment. Permits come from SDCI inside the city or the state Department of Labor and Industries elsewhere. Generators must run outdoors and away from windows and doors, which matters on tight Seattle lots.
Converting from oil or gas heat to a heat pump, adding an induction range and an EV charger is a common path, and it usually starts with a panel and service upgrade. Older homes also need knob-and-tube replacement before insulation is added.
