Monroe Township (Middlesex County), NJ Swimming Pools & Spas: Pool Permits (2026)

Section 108-12.31, Swimming pools, in Chapter 108 Land Development, sets the permit step for private pools in residential side or rear yards. Under subsection E, an applicant for a permit to construct and locate a private swimming pool must obtain approval from the Construction Official as to the suitability and adequacy of design, materials and construction or construction specifications of the pool, including all accessory equipment, apparatus and appurtenances. The application for the private swimming pool building permit identifies the pool, all accessory equipment and apparatus, the type of pool, all basic dimensions, the location of steps, diving stands and boards, and the location and detail specification of the enclosure and gate on the lot.

Subsection A applies the section's requirements to three pool types: permanent in-ground, permanent aboveground with a fence built above the top level of the pool, and temporary aboveground without such a fence. Location rules apply when the permit is reviewed. Subsection F puts an outdoor private pool not less than eight feet from the side or rear of the residence on a building lot, or beyond the building setback lines. Subsection G puts the pump of a filtration or pumping station not less than 10 feet from any side or rear property line. Subsection H requires a drainage system leading to a street or brook for pools situated or extended above ground level and less than 50 feet from an abutting property. Subsection C bars overhead electric lines across any pool or wading area, and subsection B requires pool lighting to be shielded against direct beams on adjoining property.

Pools also fall under the flood chapter. Section 44-78 requires swimming pools to be designed and constructed in accordance with the Uniform Construction Code, and states that aboveground pools are prohibited in floodways by N.J.A.C. 7:13. Under § 108-14.1 the Zoning Officer, who administers Chapter 108, cannot grant a development permit where the proposed construction or use would violate the chapter. Fence and gate standards are in subsections I and J of the same section.
