Cambridge pools deeper than 24 inches require a 48-inch barrier with self-closing, self-latching gates, per Massachusetts State Building Code 780 CMR Section 3109.
Pool barriers in Cambridge are governed by the Massachusetts State Building Code (780 CMR) Section 3109, which adopts the International Swimming Pool and Spa Code with state amendments. Any pool, spa, or hot tub capable of holding water deeper than 24 inches must be enclosed by a barrier at least 48 inches (4 feet) tall, measured from the ground outside the barrier. Openings in the barrier may not exceed 4 inches. Gates must be self-closing, self-latching, with the latch at least 54 inches off the ground or on the pool side of the gate. Above-ground pools may use the pool wall as part of the barrier if the wall is at least 48 inches and the ladder is removable or lockable. Pools require an electrical permit and plumbing permit from Cambridge Inspectional Services in addition to the building permit. Given Cambridge small lots, in-ground residential pools are uncommon but regulated identically.
