Depends on scope
Do you need a permit for Bathroom Remodel in Maricopa County?
In Arizona, whether a Bathroom Remodel needs a permit depends on the scope of the work.
Whether a bathroom remodel needs a permit depends on the scope. Cosmetic work (new tile, flooring, paint, a vanity swap, or replacing a faucet, toilet, or fixture in place without touching the shutoff valves or trap) generally needs no permit. Moving or adding plumbing (relocating the toilet, sink, or shower, or a tub-to-shower conversion), new electrical circuits, an exhaust fan vented outside, or removing a wall each require the matching plumbing, electrical, mechanical, or building permit.
