Do I need a permit for standby generator installation in Aurora?
Yes. In Colorado, standby generator installation generally requires a permit, and Aurora 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. A permanently installed standby generator in Aurora generally needs an electrical permit for the transfer switch and wiring, plus a gas piping permit for a gas unit, all applied for through the Aurora4Biz portal (aurora4biz.org). Placement is a zoning matter: the generator location must meet setbacks and any screening requirements under Aurora's Unified Development Ordinance, so confirm clearances before installing. Electrical work is reviewed under the National Electrical Code, and Aurora is moving to the 2026 NEC for applications received on or after August 1, 2026.
