Do I need a permit for water heater replacement in Austin?
Yes. In Texas, water heater replacement generally requires a permit, and Austin is no exception.
Replacing a water heater requires a plumbing permit in most Texas cities, even for a like-for-like swap, and many offer express same-day permits. Switching fuel type, moving the unit, or converting to tankless can trigger additional gas, electrical, and venting work. Confirm the scope with your local building department. Austin issues a Plumbing and Mechanical change out permit for water heater replacement through the Austin Build + Connect (AB+C) portal, and a licensed and registered plumbing contractor is required to request and be assigned to it. Standalone change out permits generally do not require formal plan review when the work is not tied to a larger building project. A homeowner performing their own work on a homesteaded single-family property may qualify for a Homeowner (Homestead) permit; confirm eligibility with Development Services.
