Small bathroom remodel (fixtures stay in place)
New York City · checked on November 6, 2026
Not fully confirmed. The city's own pages do not settle all of this answer:
- No single official page rules on a bathroom remodel as such: this card gives the rule for each part of the job.
- Whether swapping an existing exhaust fan for the same kind counts as replacing parts that affect ventilation is not stated.
Permit needed?
It depends on the job
It turns on what the job is:
- Do any fixtures move: No: Fixture swaps: no permit (ordinary repair / ordinary plumbing work by a licensed master plumber).
- Do any fixtures move: Up to 2, within 10 feet, same room: No permit; ordinary plumbing work reported on OP128 by a licensed master plumber.
- Do any fixtures move: More than that: Limited Alteration Application by a licensed master plumber, or a design professional's filing.
- Any electrical work (lights, outlets, fan wiring): Yes: Electrical permit by a licensed master electrician.
- Are you changing the bathroom's window or exhaust ventilation: Yes: Changing parts that affect required light or ventilation is not a minor alteration: permit needed.
- Opening walls beyond small patches, or touching fire-rated/load-bearing walls: Yes: The quotes on this card don't put this case in so many words: read them below, and check with the NYC Department of Buildings.
Confirm with the NYC Department of Buildings before you start.

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.
