Suffolk County, MA Swimming Pools & Spas: Safety Rules (2026)

Suffolk County pool safety is governed by layered state and federal rules. 780 CMR requires GFCI protection on all pool electrical circuits, bonding and grounding per NEC Article 680, permanent depth markers, and no-diving signage where applicable. 105 CMR 435 applies to semi-public pools (condominiums, hotels, apartment complexes, health clubs, community pools) — requiring annual inspection by the local Board of Health (Boston Public Health Commission handles Boston; Chelsea, Revere, and Winthrop have their own BOH), lifeguard requirements by pool size and usage, rescue equipment, operator certifications (Certified Pool Operator), and weekly water chemistry testing. The federal Virginia Graeme Baker Pool and Spa Safety Act (VGB Act, 15 USC §8001) requires anti-entrapment drain covers on all public pools and spas. Suffractor and automatic-circulation-shutoff systems are required for single-drain pools. Boston's larger condo and apartment pools — especially in the Seaport, Back Bay, and downtown towers — receive BPHC annual licensing. MGL c. 140 §206 provides general swimming-facility regulation authority. Fines are significant: 105 CMR 435 non-compliance can trigger immediate pool closure plus $100-$1,000/day until cured.
