Do I need a permit for water heater replacement in Marana?
Yes. In Arizona, water heater replacement generally requires a permit, and Marana 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. Marana's Need a Permit page states that a water heater replacement requires a permit application and checklist, and that a safety inspection will be conducted. Marana reviews plumbing work against its adopted 2024 International Plumbing Code with local amendments, so meet current-code venting, seismic strapping, and expansion requirements. This is independent guidance, not the Town of Marana; confirm current requirements with Marana Building Safety. 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.
