Oxford, MA Swimming Pools & Spas: Above-Ground Pools (2026)

Above-ground pool installation in Worcester County is regulated by 780 CMR (MA State Building Code), 105 CMR 435 (State Sanitary Code Ch. V), and 527 CMR 12.00 (MA Electrical Code). Any above-ground pool with 24 or more inches of water requires a building permit per 780 CMR 105 — this includes most standard above-ground pools (typically 48-54 in walls) and larger inflatable/Intex-style pools over 24 in. Electrical connections for filters, pumps, heaters, and lights require an electrical permit and GFCI protection per 527 CMR 12.00 and NEC Article 680. Barrier requirements: 105 CMR 435 requires 6-foot fence for post-1975 pools (5 ft for board/stockade), self-latching gates at 4-ft height, openings less than 3 inches. 780 CMR Appendix G allows the pool wall to serve as barrier if 48+ inches high, with ladder removed or locked when pool unoccupied. Zoning setbacks from property lines vary by town (typically 5-15 feet). Setbacks from wetlands: within 100 ft requires Conservation Commission Notice of Intent under MGL c. 131, §40. Drainage from backwashing must not flow to neighboring properties or storm drains. Pool heaters (gas or electric) require separate permits. Pool decks and surrounds may trigger additional permits and zoning review. Removal/closure at end of season — water must be drained in compliance with local discharge rules; chlorinated water cannot flow to storm drains.
