Do I need a permit for water heater replacement in Tempe?
Most likely yes. Water heater replacement usually requires a permit in Arizona. Confirm the specifics with Tempe.
Most Arizona jurisdictions require a permit to replace a water heater so that temperature/pressure relief, seismic strapping where applicable, venting, and gas/electrical connections are inspected; whether a permit is required is set locally. Switching between gas and electric, relocating the unit, or moving to a tankless system usually adds electrical, gas, or venting work and additional review. Replacing a water heater is plumbing work that Tempe generally permits under its adopted International Plumbing Code and Fuel Gas Code; confirm with permitcenter@tempe.gov whether your replacement qualifies for over-the-counter permitting. Tempe's Electrical and Gas Clearances handout notes gas water heaters may not be located in a bedroom or bedroom closet, so verify placement, especially for a relocation or fuel-type change. Converting a tank water heater to tankless, relocating it, or changing fuel type goes beyond a simple swap and requires a permit and plan review. A gas fired water heater, a change in size, or a move to a new location falls outside like for like exemptions, which cover a same size electric unit reinstalled in the same place. Gas work normally needs its own mechanical or gas permit and a pressure test, and relocating the unit can change venting, combustion air, drain pan, and expansion tank requirements.
