Installing a whole-house standby generator requires a full permit stack: electrical permit (for the transfer switch and panel integration), gas or mechanical permit (for fuel line work), and often a building permit (for the concrete pad and site plan). NFPA 37 requires minimum 5 feet from building openings; manufacturer specs typically require 18 inches from the house wall.

Required·Rule 3

Generators over 36 kW are subject to more stringent review. These larger liquid-cooled units typically exceed 50 brake horsepower, which in California triggers a Permit to Construct from the local AQMD. Other states may require commercial-scale review rather than residential. Setback and noise requirements are more strictly enforced.
