Do I need a permit for standby generator installation in Austin?
Yes. In Texas, standby generator installation generally requires a permit, and Austin is no exception.
A permanent standby generator requires an electrical permit (and usually a gas or plumbing permit for the fuel line) in Texas cities, and electrical permits are typically issued only to registered master electricians. Placement must meet manufacturer and code clearances from openings and property lines. Confirm clearances and required permits with your local building department. Austin issues an electrical Auxiliary Power permit for standby generators through the Austin Build + Connect (AB+C) portal; a licensed and registered electrical contractor is required to request and be assigned to it. A permanently installed generator on natural gas or propane usually needs a separate plumbing/gas permit by a registered plumber, and the transfer switch tie-in to the Austin Energy service must be coordinated. Generator placement is subject to setback and, on some lots, impervious cover and tree critical root zone limits; confirm siting with Development Services.
