Taunton, MA Accessory Structures: Shed & Carport Rules (2026)

Section 440-711 of the Taunton Zoning Ordinance, amended May 21, 2024 and March 11, 2025, defines an accessory structure as one that is accessory to and clearly subordinate to the primary structure and use of the lot, and states that such a structure does not need a building permit. Despite that permit exemption, the section still imposes dimensional limits: the ratio of the structure's length to its width cannot exceed three to one, preventing long, narrow sheds or outbuildings that would otherwise dodge the City's bulk standards.

For the smallest accessory structures, those of 120 square feet or less, such as a typical garden or storage shed, the side and rear setback requirement is reduced to two-thirds of what the zoning district otherwise requires, letting homeowners place a small shed closer to a side or rear lot line than a garage or larger outbuilding could sit. Structures larger than 120 square feet do not get that setback reduction and must meet the district's full side and rear setback, in addition to the three-to-one length-to-width ratio that applies to every accessory structure regardless of size.

An accessory structure application still carries a $25 fee, payable to the City even though no building permit is required for the structure itself. The section sits in Article VII, Supplementary Regulations, alongside the City's sign, lighting, and accessory dwelling standards, and is administered by the City Planner and Zoning Enforcement Officer under § 440-301A.
