Zoning Advisory Committee

The Zoning Advisory Committee of HCAM convened on August 20, 2026, primarily to discuss amendments to the Accessory Dwelling Unit (ADU) bylaw. The committee reviewed proposed changes to increase the allowable size of ADUs by right from 900 to 1,200 square feet or 75% of the principal dwelling, whichever is smaller, and considered special permit provisions for larger ADUs. There was significant discussion about whether to impose a maximum size limit on ADUs allowed by special permit, with concerns about maintaining neighborhood character and affordability. The committee also deliberated on designating the Planning Board as the special permit granting authority for ADUs, with some members noting that either the Planning Board or the Zoning Board of Appeals could fulfill this role. Additionally, the committee agreed to include a provision prohibiting ADUs from being used as short-term rentals, consistent with state law. The meeting concluded with plans to move the amended bylaw to the Planning Board for further consideration, with no immediate votes on the bylaw changes recorded during this session.
