Do You Need a Permit to Replace a Water Heater in Austin?
Permit required
Austin requires a permit for residential water heater replacement. Water heaters do not appear on the city's list of work exempt from permits, and plumbing exemptions are limited to minor repairs that don't replace or rearrange valves, pipes, or fixtures.

What to know
- Apply through Austin's stand-alone permit process (DevelopmentATX portal).
- For an urgent replacement in an occupied home, Austin Development Services can prioritize the permit as emergency repair work — call 512-974-1500 during business hours and tell staff it addresses a life-safety issue.
- Gas water heaters involve gas connections and venting that inspection specifically checks.
- Inspections are scheduled after the permit is issued; your plumber typically handles both permit and inspection.
