Do I need a permit for standby generator installation in Glendale?
Yes. In Arizona, standby generator installation generally requires a permit, and Glendale is no exception.
A permanently installed standby generator requires electrical permitting and typically a fuel/gas connection and transfer switch, so multiple trade permits and inspections usually apply; confirm the exact set with your local building department. Placement clearances from windows, doors, and property lines and, in some areas, HOA or noise rules apply; requirements are set by the jurisdiction, not statewide. A permanently installed standby generator adds new circuits and a transfer switch, which requires electrical (and, for gas units, gas) permits in Glendale under the adopted 2017 NEC and 2018 mechanical/fuel-gas codes. Generator placement must meet zoning setback and clearance rules, so show the unit and clearances on a site plan and confirm whether a Zoning Clearance Letter applies. Submittals are made electronically through Glendale's Building Safety electronic plan review and SmartGov portal; call 623-930-2800 with questions.
