Islip, NY Swimming Pools & Spas: Pool Permits (2026)

1 is Islip's district-specific swimming pool rule for the Residence BAA District, the zoning classification covering the Fire Island barrier beach. Subsection A bars any in-ground swimming pool, in-ground wading pool or similar in-ground water structure outright, citing the Town of Islip Comprehensive Plan's finding that Fire Island must keep serving as a natural barrier for the Great South Bay and as a low-intensity recreational resource. Subsection B records the Town Board's finding that such uses represent overintensification, an intrusion on Fire Island's living style, and an unnecessary accessory use given the beach access already available to residents.

Subsection C then permits aboveground pools as of right as an accessory use, but only if the parcel has, and continues to have, a lot area of not less than 12,000 square feet, along with compliance with the rest of Article XI and Article XXVIII. 2) was eliminated: under Subsections D and E, the ZBA may renew that exception for up to three years at a time, but only on proof, including a licensed New York physician's statement, that the owner, spouse or child needs the pool for aquatic therapy for a neurological or muscular condition, and a nontransferability statement must be recorded against the property with the Suffolk County Clerk.

Chapter-wide, § 68-384 in Article XXVIII independently defines an "aboveground swimming pool" as one that is self-supporting and no more than 18 inches below grade at any point, the line that separates it from an "in-ground" pool everywhere else in Town.
