Do I need a permit for water heater replacement in Oro Valley?
Yes. In Arizona, water heater replacement generally requires a permit, and Oro Valley 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. Replacing a water heater requires a plumbing permit in Oro Valley under the adopted 2018 IPC and IFGC with local amendments, so confirm requirements with Oro Valley Permitting. Installations must meet code for combustion air, venting, seismic strapping, and the temperature and pressure relief line. 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.
