Do I need a permit for plumbing fixture or repiping in Phoenix?
Yes. In Arizona, plumbing fixture or repiping generally requires a permit, and Phoenix is no exception.
Repiping water supply or drain lines requires a plumbing permit and inspection in Arizona jurisdictions; opened walls must be inspected before they are closed up, and the applicable plumbing code edition is set by the local jurisdiction. Approved piping materials and connection methods can differ between cities and counties because each adopts its own code, so confirm accepted materials before purchasing. Phoenix requires a permit to move or add sinks, toilets, and tubs, so a whole-house repipe that reroutes or replaces supply or drain lines is permitted work, even though swapping an existing fixture in place is exempt. Any gas piping modification is separately called out by Phoenix as requiring a permit.
