Do I need a permit for water heater replacement in San Antonio?
Yes. In Texas, water heater replacement generally requires a permit, and San Antonio 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. The DSD Home Remodeling FAQ requires a plumbing permit to install or replace a water heater; for an emergency swap, a Limited Service Repair permit lets the licensed plumber file within three days. Only a Texas state-licensed plumbing contractor can pull the permit; a homeowner generally cannot self-pull a plumbing permit in San Antonio. A gas water heater's flue, venting, and gas connection are inspected as part of the work; confirm the current permit fee on the DSD fee schedule.
