Required code upgrades for this install

Mark each item as you walk the job.

    This checklist references the 2021 IPC, IFGC, IMC and NEC as commonly adopted. Code sections and adoption vary by jurisdiction — the Authority Having Jurisdiction (AHJ) and any local amendments govern. Verify final requirements with your local inspector.

    About this tool

    Water heater code checklist questions

    Which codes does this reference?
    The 2021 International Plumbing Code (IPC) for water/relief/pan/pressure items, the 2021 International Fuel Gas Code (IFGC) for combustion air, sediment trap, connectors, and gas shutoff, the IMC/IRC for attic and garage install requirements, and the NEC for electric water-heater circuits. Adoption and amendments vary — your AHJ governs.
    Why do the items change?
    The checklist is equipment-aware: pick gas and you get combustion air, sediment trap, and gas-connector items; pick electric and you get disconnect, wire gauge, and breaker items; pick attic or garage and the catwalk or 18" elevation items appear. It shows only what actually applies.
    How does this keep money on the table?
    Missed code upgrades — the expansion tank, T&P re-route, pan, sediment trap, gas connector — are exactly what gets left off a quick quote and then eaten as a callback. Listing every required item, with its code section, makes each one a defensible line on the estimate.
