Permit Requirements

Electrical Panel permit in Tempe, AZ

Yes — you need a permit for electrical panel work in Tempe.

Upgrading or replacing an electrical service panel needs an electrical permit. The only exempt electrical work of this kind is repair or replacement of a listed over-current device of the same required capacity in the same location, and that exemption expressly excludes main over-current devices. A service panel change involves the main over-current device and usually a capacity change, so it is not exempt.

How to pull the permit

  1. Put together a site plan showing where the work goes, with dimensions.
  2. Apply through the Tempe building department.
  3. Pay the permit fee when the permit is issued. Work done before that isn't covered.
  4. 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

Tempe'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?

Tempe 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.
