Worcester County, MA Swimming Pools & Spas: Pool Permits (2026)

Swimming pool permits in Worcester County are issued municipally because county government was abolished in 1998, but the permit standards are uniform statewide under the Massachusetts State Building Code (780 CMR, 10th edition adopted 2024). Municipalities cannot adopt lesser standards under MGL c. 143 §98 but may adopt stricter local provisions. In the City of Worcester, the Department of Inspectional Services (ISD) Building Division issues permits for in-ground and above-ground pools exceeding 24 inches of water depth, spas, and permanent hot tubs. The permit process requires plot plans showing setbacks, barrier/fence plans, electrical plans with GFCI protection on all pool circuits (NEC Article 680 as adopted by 527 CMR 12.00), and drainage. A plumbing permit is typically required alongside the building permit. Final inspection is required before use. Fitchburg, Leominster, Gardner, Shrewsbury, Westborough, Northborough, Auburn, Millbury, Webster, and Milford building departments issue similar permits. Semi-public pools (condominium, apartment complex, hotel) are additionally regulated by the Massachusetts Department of Public Health under 105 CMR 435 and inspected by local Boards of Health.
