Water Heater permit in Houston, TX
Yes — you need a permit for water heater work in Houston.
Replacing or moving a water heater needs a permit. The model code only exempts small jobs like stopping a leak or swapping a minor part. Pulling out an old heater and installing a new one counts as new work, and it is regulated plumbing (and gas, for a gas heater), so a permit and inspection are required.

How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the Houston 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.
If you skip it
Houston's code doesn't set a specific fine for this work. In practice the department can issue a stop-work order, and unpermitted work tends to surface during a sale, when the buyer's inspector or the title company asks for it.

I already built it without a permit. What now?

Does unpermitted work cause problems when selling the house?
