Tiny home rules in Lynn, MA — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Lynn bans tiny homes on wheels as dwellings — ADUs may not occupy RVs, campers, or structures on wheels. A tiny home on a permanent foundation must meet the MA Building Code and accessory-structure zoning limits.
Lynn does not recognize a movable tiny home as a legal dwelling. Under the 2025 Lynn Zoning Ordinance (Section 9.B.3.a), ADUs may not be located in temporary structures, mobile structures, campers, recreational vehicles, or other structures on wheels. A tiny house parked on a trailer is treated as an RV, not a residence. A tiny home built on a permanent foundation can qualify as an ADU if it meets Section 9.B: by right on single-family lots, no larger than 900 square feet or 50% of the main home, under 15 feet as a detached accessory structure, and one added parking space unless near transit. All such construction requires a building permit under the MA Building Code (780 CMR).
Living in a tiny home on wheels or an RV as a permanent residence violates the zoning ordinance and draws correction orders. Building a foundation tiny home without permits triggers stop-work orders and retroactive permit penalties.
