Water heater permit checklist — New York City, New York
Assembled from New York City’s own published permit rules. Every line below is quoted from a city document and linked to it. Nothing here is generated, estimated, or inferred from another jurisdiction.
Do you need a permit?
New York City does not require a permit for a water heater.
In buildings classified as residential occupancy groups occupied by five families or fewer, the replacement of a gas water heater, gas furnace, or a gas-fired boiler with a capacity of 350,000 BTU (103 kW) or less is ordinary plumbing work that may be performed without a permit, where the existing appliance shutoff valve is not moved and the plumber has inspected the chimney and found it to be in good operational condition.
