Fitchburg, MA Swimming Pools & Spas: Fencing Requirements (2026)

Fitchburg has not adopted a stand-alone pool barrier ordinance; instead the Building Department enforces 780 CMR Appendix G (the Massachusetts Swimming Pool and Spa Code, based on the 2015 ISPSC) for all residential and public pools deeper than 24 inches. Appendix G AG105 requires a barrier at least 48 inches above finished grade on the exterior side; a maximum 2-inch gap below the barrier; openings that will not pass a 4-inch sphere; and self-closing, self-latching gates with the latch at least 54 inches above grade (or shielded from outside access if lower). Hot tubs, spas, and above-ground pools follow the same rules unless equipped with an approved safety cover meeting ASTM F1346. Public and semi-public pools additionally fall under 105 CMR 435 (DPH State Sanitary Code Chapter V), administered locally by the Fitchburg Board of Health, which mandates fencing, depth markings, and lifeguard/operational standards. On the zoning side, Fitchburg Zoning Code Ch. 181 (eCode360) treats swimming pools as accessory uses: pools and uncovered decks must be set back at least 6 feet from any front, side, or rear lot line and may not encroach into the front yard setback. Fences in the front yard may not exceed 6 feet; stockade fences are capped at 6 feet, chain-link fences at 8 feet, with Board of Appeals special permits available for exceptions. A building permit and electrical permit are required before installation; the Building Commissioner inspects the barrier before the pool may be filled or used.
