The answer

Replace a gas range or connect a gas appliance (stove, oven, dryer)

New York City · checked on November 6, 2026

Permit needed?

It depends on the job

It turns on what the job is:

  • Is there an existing gas shut-off valve that stays, is easy to reach and is in good shape (no corrosion): Yes; Do you need new or rerouted gas pipe: No: No permit: replacing a domestic range, oven, stove, barbecue or clothes dryer (or its appliance connector) is ordinary plumbing work. A licensed master plumber does it and reports it on the monthly OP128.
  • Is there an existing gas shut-off valve that stays, is easy to reach and is in good shape (no corrosion): No / it has to move, or Do you need new or rerouted gas pipe: Yes: Permit needed: Limited Alteration Application by a licensed master plumber in DOB NOW: Build ('Gas Stove (Residential)' and rerouting existing gas piping are on DOB's LAA replacement list).

Only when:

  • Existing appliance shutoff valve remains, accessible, good working condition

Filing: OP128 monthly report (no permit) or Limited Alteration Application in DOB NOW: Build.

Confirm with the NYC Department of Buildings before you start.

The city's own words on the permit (6 quotes)

License needed?

Licensed master plumber; helpers need a gas work qualification and must work under the plumber's direct and continuing supervision.

DCWP's home improvement contractor license: not needed. DCWP lists plumbing as work not requiring a Home Improvement Contractor license; its exam guide exempts plumbers acting within their licensed craft. A contractor who also does non-plumbing home improvement work over the threshold needs the HIC license for that part.

Confirm with the NYC Department of Buildings for trade licenses, and NYC Department of Consumer and Worker Protection for the home improvement license.

Sales tax on the invoice?

New York State's answer, from its tax department's pages. The sales tax rate, with any local share, was not checked here.

It depends on the kind of work, so here is each answer, side by side:

Repairing a thing
Taxed
Repairing a home or building
Taxed
Installing
Depends
New build
Not taxed · see the caveat

Installing: Installing something that becomes a permanent part of the building (water heater, kitchen cabinets) is a capital improvement and not taxable. Installing things that do not become part of the building (freestanding appliances, above-ground pools, canvas awnings, weather stripping) is taxable.

New build: The contractor pays sales tax on the materials.

Worth knowing: The certificate the customer gives for capital-improvement work (Form ST-124) is not quoted here.

Confirm with the New York State Department of Taxation and Finance. Every answer for New York: sales tax on labor in New York.
