Indiana building permits, explained
Indiana delegates building-code enforcement to local building commissioners. Indianapolis/Marion County runs its own permitting; suburbs and counties each have offices.
Who issues the permit
Your city or county building department (Indianapolis: state/local combined office)
Can homeowners pull their own permit in IN?
Owner-occupants can commonly pull permits for their own single-family residence work — confirm with your local office; some trades require licensed contractors regardless
Common jobs and their permits
| Job | Permit status |
|---|---|
| Water heater replacement | Plumbing permit typically required |
| HVAC replacement | Mechanical permit typical |
| Panel/service upgrade | Electrical permit + inspection, always |
| Roof replacement | Often required; varies by municipality |
What happens without a permit
Unpermitted work surfaces at point-of-sale inspections and can require retroactive permits with penalties
