Water Heater permit in San Antonio, TX
Yes — you need a permit for water heater work in San Antonio.
Replacing a water heater is regulated plumbing work. The plumbing exemption list covers only stopping leaks, clearing stoppages, repairing leaks in pipes or fixtures, and removing and reinstalling a toilet without changing any valves, pipes, or fixtures. A water heater is not on that list, so a permit is required. A homeowner may pull the plumbing permit for a homestead they live in, or a Responsible Master Plumber may pull it.

How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the San Antonio building department.
- Pay the permit fee when the permit is issued. Work done before that isn't covered.
- Book each inspection listed on the permit as the job reaches that stage.
Either of you can pull it. When a contractor does the work, it is normally their job.

Does unpermitted work cause problems when selling the house?
