Replace a faucet or sink
New York City · checked on November 6, 2026
Not fully confirmed. The city's own pages do not settle all of this answer:
- No official page says whether someone other than a licensed master plumber, such as a handyman with a home improvement license, may swap a faucet or sink as an ordinary repair. The city's pages give two answers on it, shown on this card.
Permit needed?
It depends on the job
It turns on what the job is:
- Are you moving the sink or changing pipes past the shut-off valves or the drain trap: No, same spot (swap only): No permit: ordinary repair (fixture/faucet from the exposed stop valve to the inlet side of the trap).
- Are you moving the sink or changing pipes past the shut-off valves or the drain trap: Moving it up to 10 feet in the same room: No permit, but it is ordinary plumbing work: a licensed master plumber must do it and report it on the monthly OP128 report with the fee.
- Are you moving the sink or changing pipes past the shut-off valves or the drain trap: Moving it further, or adding a new sink: Permit needed: a Limited Alteration Application (LAA) filed in DOB NOW: Build by a licensed master plumber; work beyond the limited-alteration categories needs plans from a registered design professional.
Only when:
- Swap stays between the exposed stop valve and the inlet side of the trap.
Exceptions:
- Ordinary plumbing work relocation does not apply in health care facilities.
Filing: None for a swap; OP128 monthly report for ordinary plumbing work; Limited Alteration Application in DOB NOW: Build for larger changes.
Confirm with the NYC Department of Buildings before you start.

License needed?
Licensed master plumber (or a person under the plumber's direct and continuing supervision).
- Ordinary plumbing work (relocation) must be done and reported by a licensed master plumber.
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.
