Trenton, NJ Swimming Pools & Spas: Fencing & Safety Requirements (2026)

" For in-ground pools, the code sets both a location rule and a fence rule. Location: an in-ground pool "is not permitted in a required setback or six feet from a lot line, whichever is greater," meaning the pool itself must clear the larger of the district's normal building setback or a flat six-foot buffer from every lot line. Fencing: an in-ground pool "must have a fence surrounding the pool deck adjacent to the pool of a minimum of four feet to a maximum of six feet," so the fence has to enclose the pool deck itself, not just the yard perimeter, and has to fall within that four-to-six-foot height band.

Aboveground pools are treated somewhat differently: they need only a three-foot setback from any lot line, but the ordinance requires that "the lot where an aboveground pool is located must be fenced," again to a minimum of four feet and maximum of six feet in height. In practice this means an aboveground pool owner is fencing the whole lot (or at least the yard containing the pool) rather than just the pool deck, since the code addresses the lot rather than the deck for that pool type.

S does not separately spell out a self-closing or self-latching gate mechanism; homeowners should check with the Building Department on whether the state Uniform Construction Code's barrier requirements add that detail on top of this zoning standard.
