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

Section 116-2 draws the line: a SWIMMING POOL is an artificial pool of water having a depth at any point of more than 18 inches and a surface area of greater than 100 square feet, designed or intended for the purpose of bathing or swimming and including all appurtenant equipment. Both figures come from the definition, which is written around depth and surface area.

Section 116-9A(10) then governs a pool that meets it. A pool is deemed a structure subject to the chapter's provisions on structures, and it can be installed on a lot in any district as an accessory use provided that an outdoor pool is in the rear yard or a side yard, it is not nearer than 20 feet to any lot line, its area is included in computing building area for the maximum building area percentage, and a lot does not contain more than one swimming pool. Subsection (b) adds an enclosure requirement of a fence or wall not less than four feet in height. An accessory building designated as a poolhouse has to be located no further than 25 feet from the pool under § 116-9A(1)(g).

Because a pool is a structure, Chapter A119 applies. Section A119-1A prohibits commencing the erection of any building or structure without first obtaining a separate building permit from the Building Inspector, except for ordinary repairs that are not structural. The application states the use, the valuation of the proposed work and the owner's information, and carries duplicate copies of plans and specifications including a plot plan drawn to scale showing the location and size of all proposed new construction and the distance from lot lines under § A119-1E. The Building Inspector can waive the plans requirement for minor alterations. Section A119-2A(1)(b) lists the fee as swimming pools: 1.5% of the estimated cost of construction and materials.

Section 43-15A adds that all swimming pools must be constructed and maintained in accordance with the appropriate sections of the New York State Property Maintenance Code. Section 43-15 also carries energy conservation rules for pool pumps, filters and heaters, including sizing filters installed after July 1, 2010 using NSF/ANSI 50 standards.
