Do I need a permit for standby generator installation in Littleton?
Permit required
Yes. In Colorado, standby generator installation generally requires a permit, and Littleton is no exception.
A permanently installed standby generator requires a state electrical permit for the transfer switch and wiring, plus a fuel-connection permit for gas units, so multiple state and local permits typically apply. Placement clearances from windows, doors, and property lines, plus any local noise or HOA rules, are set locally; confirm the full set with your building department before installing.
