Water Heater permit in Chattanooga, TN
Yes — you need a permit for water heater work in Chattanooga.
Replacing or moving a water heater needs a plumbing permit. The state exemption for plumbing only covers stopping leaks and clearing stoppages, not swapping out a water heater. The city plumbing fee schedule even lists a set charge for each water heater, which shows a permit is expected.

How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the Chattanooga 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.
Your contractor pulls this one, not you. Ask to see the permit before work starts.
If you skip it
Chattanooga'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.

Questions people ask
How much does a water heater permit cost in Chattanooga?
The plumbing permit fee schedule charges $6.00 for each water heater and/or vent.. Valuation-based fees mean the number depends on what the job is worth, so the department quotes it when you apply.
I already built it without a permit. What now?
Chattanooga can issue a stop-work order and require you to apply after the fact, sometimes with an extra fee. Work that was covered up may have to be opened for inspection. Full walkthrough here.
Does unpermitted work cause problems when selling the house?
Often, yes. A buyer's inspector or the title company may flag it, and lenders can balk at financing a home with open or missing permits. What to do about it.
Do I pull the permit or does my contractor?
Your contractor does. A licensed contractor pulling their own permit is the normal arrangement — if one asks you to pull it in your name, treat that as a warning sign, because it moves the liability to you.
