Massachusetts has recently enacted legislation that simplifies the process for homeowners to add Accessory Dwelling Units (ADUs) to their properties. While the state law provides a general framework, individual cities and towns may have specific regulations regarding ADUs. It’s essential to consult local ordinances to ensure compliance.
