Do I need a permit for standby generator installation in Chandler?
Yes. In Arizona, standby generator installation generally requires a permit, and Chandler 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 is not an ordinary repair under Chandler's manual, so an electrical permit is required. For a natural-gas generator, the manual requires a gas riser schematic starting at the meter with line sizes and BTU ratings, gas pipe buried at least 12 inches below grade, and a pressure test, so gas work is permitted alongside the electrical. Generator placement must meet zoning setback and clearance rules; show the unit and clearances on a plot plan, and call Arizona Blue Stake (811) before digging any gas trench.
