Full Breakdown
Milton's zoning code addresses small sheds through Sec. 28(13), "Minor accessory structures and obstructions," which defines minor accessory structures generally as features under 16 feet in height and under 200 square feet in area that the zoning administrator finds similar in size and function to those listed in the accompanying table. " That is a tighter cap than the general 200-square-foot minor-accessory threshold in the section's opening definition. A shed larger than 120 square feet no longer qualifies for placement inside the setback and instead must meet the full accessory-structure setbacks for its zoning district, for example 3 feet from the side and rear lot lines and an 18-foot height ceiling in the SR-7 district under Sec.
11(7). The table also lists related yard features on the same page, gazebos and picnic shelters share the identical 16-foot/120-square-foot cap, while items like arbors, flagpoles and benches carry their own separate limitations. The zoning administrator and building official retain authority to add requirements to protect health and safety or code compliance on a given lot.
Violations & Fines
Placing an oversized shed inside a required setback, or building one that exceeds the district's full accessory-structure standards without a variance, is enforced by the zoning administrator under Sec. 78-10.60. Sec. 1-14 sets forfeitures at $50.00 to $500.00 for a first offense and $100.00 to $1,000.00 for a repeat offense, plus prosecution costs, with jail time possible if a forfeiture goes unpaid.
