Do I need a permit for standby generator installation in Indianapolis?
Most likely yes. Standby generator installation usually requires a permit in Indiana. Confirm the specifics with Indianapolis.
Electrical connections fall under Chapters 34 to 43 of the 2020 Indiana Residential Code and gas piping under its fuel gas chapter as amended; permits and inspections are issued locally. Before digging, the person responsible must notify the statewide one-call association at least two full working days before work begins (IC 8-1-26-16). The state does not issue permits for or inspect one- and two-family dwellings; if the local unit has no building permit ordinance, no state office issues one instead, but the 2020 Indiana Residential Code still applies to the work.
Local detail for Indianapolis: Indianapolis and Marion County have a consolidated city-county government. The City of Indianapolis issues building permits for Indianapolis and the rest of Marion County, except in cities such as Lawrence that run their own building departments.
