Water Heater permit in Chandler, AZ
It depends — some water heater work in Chandler needs a permit, some doesn't.
You do not need a permit to swap a water heater for one of equal or lower rating in the same spot at a single home (a Group R-3 dwelling). That covers a like-for-like gas water heater of equal or lower BTU capacity, or a like-for-like electric water heater of equal or lower amperage. You do need a permit if you move the water heater to a new location, or if the new unit has a higher rating than the old one.

How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the Chandler 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.
If you skip it
Chandler'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.

Rules stop at the city line. If your lot is near a boundary, or you work across several towns, this is where they differ.

Questions people ask
My water heater is right at the limit. Does that count?
The exemption has to fit exactly — if the code says a size or height, being at or under it keeps you exempt, and going a single inch over doesn't. When you're close to the line, measure before you buy materials, and call the department if the number is borderline.
I already built it without a permit. What now?
Chandler 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.
