What to know
- Water heater replacement is listed in Phoenix's Residential Over-the-Counter Permits guideline under express permits ('miscellaneous plumbing, mechanical or electrical permits in which minimal or no plans are required').
- Permits for minor work that don't require plans can also be obtained through the city's online permitting portal (PDD Online).
- Over-the-counter issuance applies when the application is complete and there are no outstanding site issues.
