Bill > H1277

This bill amends Massachusetts state law to prohibit municipalities from banning or requiring a special permit for accessory dwelling units (ADUs) within single-family homes on lots of at least 5,000 square feet or large enough to meet septic requirements. Municipalities can impose reasonable regulations on the size and appearance of ADUs, require the principal dwelling or ADU to be owner-occupied, and limit the total number of ADUs to no less than 5% of single-family homes. The bill also allows exterior alterations to the principal dwelling to provide separate access to the ADU without a special permit, as long as setback requirements are met. However, the bill does not override building, fire, health, or environmental code requirements, and it allows municipalities to prohibit or restrict the use of ADUs as short-term rentals.
