Do You Need a Permit for a Pool in New York City?
It depends on the pool, and the threshold is not depth. DOB rule 1 RCNY 101-14 exempts an outdoor in-ground or above-ground pool accessory to a one- or two-family dwelling when it is limited to 400 square feet in area, the distance from the edge of an in-ground pool to any building or lot line is greater than the depth of the deepest part of the pool, and either an existing slop sink is available for indirect waste or a plumbing permit is obtained to install one. Miss any of those and the pool is filed as an alteration by a PE or RA in DOB NOW. Whatever the filing status, the barrier, setback and electrical rules below still apply: NYC311 says you may need a permit at a 1- or 2-family building and sends you to DOB for the full requirements.

How Much Does a Pool Permit Cost in NYC?
For an exempt pool the DOB fee is zero, apart from the separate electrical permit. A pool that files is an alteration under Administrative Code Table 28-112.2 (as amended by Local Law 128 of 2024, in effect since December 21, 2025). At a one-, two- or three-family home that is a $130 minimum covering the first $5,000 of job cost, plus $2.60 for each additional $1,000: a $60,000 in-ground pool files at about $273, a $120,000 one at about $429. The electrical permit is fee-per-unit under DOB rule 1 RCNY 101-03 (a $40 initial application fee plus per-outlet and per-horsepower units), and the PE or RA who prepares the plans charges separately, at market rates DOB does not set.
Setbacks, Barriers and Wiring
NYC311 gives the setbacks for a residential pool: on a lot 25 feet or wider the pool must be at least 5 feet from any lot line, on a narrower lot at least 3 feet from any side lot line, and no overhead electrical conductors may run within 22.5 feet of the pool. The Building Code (§3109.5, private swimming pools) sets the barrier: at least 48 inches above grade on the outside, no more than 2 inches of clearance at the bottom, no opening a 4-inch sphere can pass through, and a self-closing, self-latching gate whose latch sits at least 40 inches above grade behind a child-proof lock. NYC311 states it as a 4-foot fence all the way around in-ground pools with a closed, child-proof, self-closing gate. During construction, DOB requires a temporary barrier under BC 3109.6.
Who Pulls a Pool Permit in New York City?
DOB states that permits for pool installation are only issued to a Licensed General Contractor, and for one- to four-family homes the contractor also needs a Department of Consumer and Worker Protection Home Improvement Contractor license. The plans come from a Registered Design Professional (PE or RA). Plumbing for a new slop sink or drain is a Licensed Master Plumber's job, and every piece of pool wiring is a Licensed Master Electrician's, each with its own DOB permit.
How to Get a Pool Permit in New York City
Size the pool against the exemption
Up to 400 sq ft at a 1-2 family home, in-ground edge farther from buildings and lot lines than its depth, slop sink available: no DOB filing for the pool itself.
Check setbacks and overhead wires
5 ft from lot lines on 25-ft-plus lots, 3 ft from side lines on narrower lots, no overhead conductors within 22.5 ft.
File if required
A PE or RA files the alteration in DOB NOW; fee $130 minimum for the first $5,000 of job cost plus $2.60 per $1,000 above that at a 1-3 family home. Permit issued to a Licensed GC with an HIC license.
Pull the electrical and plumbing permits
A Licensed Master Electrician files for the pump, lights and bonding; a Licensed Master Plumber handles a new slop sink or drain.
