The following is for guidance only, no document could coverall possible scenarios or situations. Please consult with the building divisionshould you have additional questions regarding pool barriers after reviewingthis document.
The barrier provisions contained within the MassachusettsState Building Code (780 CMR) apply to indoor and outdoor swimming pools andhot tubs with water depths greater than 24”. This includes “portable” and “inflatable”swimming pools. An approved safety cover for a hot tub would satisfy thebarrier requirement. Required pool barriers or fences must be at least 48” highand constructed to prevent climbing by children. Access gates must be self-closingand self-latching, swinging away from the pool with hardware arranged so thatthe gate cannot be opened from the side opposite the pool. Below are someillustrations of code compliant pool barriers.
For above ground pools, the wall of the pool may serve asthe barrier, provided it meets the 48 inch height requirement and access to thepool is via a “closable, lockable ladder” A removable ladder is NOT acceptableunless it is closable and lockable.
In addition to outside walls or fences as barriers any doorsfrom the dwelling (where the walls of the dwelling are used as a portion of thepool enclosure) with direct access to the pool area must be equipped with audiblealarms. The alarm must be audible in all portions of the home and activatedwhen the door is opened.

If the fence is over seven feet in height, a building permit is required. There is no requirement regarding which way the fence faces. The State Building Code, 780 CMR regulates the height of the fence. Fence can be installed close to the property line, as long as no part of it extends over a neighbor’s property.
