ADU rules in Fitchburg, MA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
MA Affordable Homes Act (Ch. 150, Acts of 2024, §8), effective Feb 2, 2025 — ADUs allowed by right in single-family zones statewide, max 900 sq ft or 50% of principal dwelling GFA. Fitchburg Zoning Chapter 181 governs setbacks, height, and bulk. No owner-occupancy requirement.
Massachusetts enacted ADU provisions as part of the 2024 Affordable Homes Act, building on MGL c.40A §3 and the MBTA Communities Act. Single-family homeowners may create one ADU by right. Municipalities cannot prohibit ADUs on single-family lots. This is a recent mandate and implementation is still developing across municipalities. Fitchburg may adopt reasonable regulations including size limits, setbacks, and design standards but cannot effectively ban ADUs.
Municipalities cannot deny conforming ADU applications. Unpermitted ADU: standard building code enforcement under 780 CMR.
