Bill > H4707

This bill introduces a legal definition for "movable tiny houses" in Massachusetts, establishing them as transportable dwelling units under 400 square feet that can be used as primary residences or accessory dwelling units. The bill requires state transportation and motor vehicle agencies to create a new registration category for these structures, with a $100 title certificate fee. Movable tiny houses must be built on an approved chassis, meet state building code standards with some relaxed insulation requirements, and can be placed on residential lots. Owners have 180 days after placement to establish a permanent address, energy and water sources, and wastewater system, after which they must pass an inspection to receive a certificate of occupancy. The legislation allows cities and towns to create their own rules for movable tiny houses, but prohibits them from establishing design criteria that would effectively ban such structures. Municipalities are also encouraged to incentivize tiny house parking through tax abatements. This bill aims to provide a clear legal framework for tiny houses, making it easier for Massachusetts residents to use these compact, mobile dwelling units as legitimate housing options.
