Massachusetts ADU Laws
In early February 2025, the Commonwealth of Massachusetts passed a law allowing the official construction and use of ADUs. What’s an ADU? Chances are you already know what one is but didn’t know the official term. Accessory Dwelling Unit, or ADU, is commonly known as an in-law apartment in New England. Nowadays, most ADUs are entirely separate buildings from the original home instead of turning a basement into a living area. With Massachusetts officially recognizing ADUs, it’s only a matter of time before they start popping up all over the state.
Right now, America is in a housing crisis, and to combat that, many states have written new laws allowing the construction and residence of Accessory Dwelling Units. ADUs are sometimes referred to as tiny homes or in-law apartments and are suitable for single-family residences only. The dwellings provide housing for those seeking to rent, but also family members who need extra care. Since the units can be rented as supplemental income for homeowners, the new housing option benefits homeowners and renters alike.
These units must adhere to specific criteria to be lawful. ADUs can be separated into different types: Attached, Detached, Above Garage, Garage Conversion, Interior Lower Level, and Interior Upper Level. Furthermore, ADU must adhere to specific laws to maintain legality. An ADU cannot be more than 900 square feet, and towns/cities have the right to force their own regulations regarding Title V requirements, reviewing of ADU plans, ADUs being used as short-term rentals, and ordinances involving ADU dimensions.
Besides tackling the housing crisis, this new ADU law is a game-changer for establishing more freedom for homeowners. ADU permitting is now more streamlined and in a place where homeowners are not being denied when requesting permits. Another benefit of these units is that those who are older than 60 may qualify for better financing opportunities or no-interest financing.
Construction laws are constantly changing, and Ufema is here to keep up with those changes. Accessory Dwelling Units are here to aid those looking for a smaller living space, and those who desire to take care of their loved ones while maintaining a separate living space. Each project should be discussed with a professional who can make sure the proper design and building codes are met for the job.
