Do I need a permit for water heater replacement in Peoria?
Yes. In Arizona, water heater replacement generally requires a permit, and Peoria is no exception.
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. Peoria specifically names a homeowner replacing a water heater as an example of a project that needs to be permitted through the Development and Engineering Department, so even a like-for-like swap is permitted work here. The plumbing work falls under Peoria's amended 2018 International Plumbing Code, with gas connections under the 2018 International Fuel Gas Code; confirm the current path with the Development Services Center at 623-773-7225. Relocating the water heater, changing fuel type, or modifying gas piping adds scope beyond a simple replacement. 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.
