Phoenix, AZ · Official data from city building dept · Last updated: 2026-04-17
Water heater replacements completed by a licensed contractor do NOT require a permit in Phoenix. However, DIY (homeowner-installed) water heater replacements DO require a permit.

- •Water heater replacement performed by the homeowner (DIY)
- •Changing from gas to electric or vice versa
- •Relocating the water heater to a new location
- •Installing a tankless water heater (new installation)
✅ No Permit Needed When…
- •Water heater replacement completed by a licensed contractor (same location, same fuel type)
- •Replacing a like-for-like unit in the same location by a licensed plumber
💡 Additional Information
This is one of the most misunderstood rules in Phoenix. The key factor is WHO installs it: licensed contractor = no permit needed. DIY = permit required. Estimated permit fee if required: $75–$150.
