Installed generators require Zoning Review. Generators should be located at the side (not in a required yard “setback”) or anywhere in a rear yard (including setback). Creek and noise considerations may apply to the review.
Generators are defined as stationary or portable compression ignition engines used to provide power to a structure or for a given activity. Zoning review, Electrical, and Plumbing Permits are required. For large generators, a Building Permit is required.
