Full Breakdown
The City of Lowell Division of Development Services administers swimming pool barrier rules through the Massachusetts State Building Code (780 CMR), which Lowell enforces locally. 4 (Residential swimming pools), requires the top of the barrier to be at least 48 inches above grade measured on the side facing away from the pool, with a maximum 2-inch clearance between grade and the bottom of the barrier, and openings that will not allow passage of a 4-inch-diameter sphere. Pedestrian access gates must open outward away from the pool and be self-closing and self-latching; where the latch release is less than 54 inches from the bottom of the gate, the release must be on the pool side at least 3 inches below the top of the gate. These barrier requirements are verified at final inspection before the pool can be used.
Violations & Fines
The Division of Development Services will not finalize or close out a pool permit until field inspection confirms the barrier, gate, and (where applicable) door alarms comply with 780 CMR 3109.4. A non-compliant or unenclosed pool may be cited as a safety hazard and the permit held open until corrected.
