    Frequently Asked Questions

    What plumbing code does New York use?

    New York currently follows International Plumbing Code 2021 for plumbing work. Always confirm the in-force edition with the local Authority Having Jurisdiction (AHJ) — county or city amendments can apply.

    Do I need a permit for plumbing work in New York?

    Most plumbing work in New York — including new installations, system replacement, and gas-fueled appliance hookups — requires a permit from the local building department and an inspection at completion. Homeowner permits are typically allowed for owner-occupied residences; commercial work requires a licensed contractor.

    Where do I check New York plumbing code amendments?

    Local jurisdictions (city or county) often publish amendments on the state's building-codes board website or in the municipal code. The current International Plumbing Code 2021 text is published by its model-code body (ICC, IAPMO, or NFPA depending on the trade).

    Reference guidance only — adoption editions and local amendments vary by city or county. Always confirm requirements with your local Authority Having Jurisdiction (AHJ) before designing, permitting, or constructing.
