What's different about generator installation in Boulder
A portable generator through an outdoor inlet and interlock is a lower-cost option. Natural-gas standby generators are less common as the city moves toward electrification. Permits come from the City of Boulder's Planning and Development Services.
Historic homes may have knob-and-tube or small services, and many owners are adding heat pumps, solar, batteries and EV chargers as the city pushes electrification.
