Lynn, MA Short-Term Rentals: Occupancy Limits (2026)

Section 12 of the Zoning Ordinance defines the two owner-occupied short-term rental categories by their occupancy ceiling. ' A Limited Share Unit is 'a dwelling unit that is the Operator's Primary Residence, a portion of which is offered as a short-term rental while the Operator is present,' capped at 'three bedrooms or six guests in a Limited Share Unit, whichever is less,' and 'one bedroom must be reserved for the Operator' so the household living there year-round always keeps a room out of the rental pool.

A third category, the Owner's Adjacent Unit, covers a unit in the same two- or three-family building as the Operator's primary residence but is not itself the primary residence; Section 12 limits an Operator of an Owner-Adjacent Unit to registering and using only one such unit as a short-term rental, and confines the category to two-family and three-family dwellings where every unit is owned by the same owner-occupant. None of the three definitions carve out an exception to the 'whichever is less' occupancy math.
