Planning Board revises accessory dwelling unit regulations ahead of town meeting

The recent Planning Board meeting in Northborough, Massachusetts, held on March 4, 2025, focused on significant updates to the town's accessory dwelling unit (ADU) regulations, reflecting ongoing efforts to adapt to evolving housing needs and state mandates. As the town prepares for a pivotal town meeting in April, discussions highlighted the complexities surrounding the implementation of three distinct sets of ADU regulations that will be in effect this year.

During the meeting, officials noted a lack of formal applications for ADUs but reported a surge in inquiries from residents. Many potential applicants have been advised to wait until after the upcoming town meeting, as the regulatory landscape is expected to change significantly. The current regulations, which include an older set, a state-mandated set, and a proposed new set, have created confusion among residents and officials alike. The Planning Board emphasized the importance of clarity in the regulations to avoid complications during the permitting process.

Key modifications to the ADU bylaw were discussed, including aligning local definitions with state standards. This alignment aims to simplify the regulatory framework and ensure compliance with state laws. Notably, the board agreed to adopt a more flexible approach regarding the placement of detached ADUs, allowing for their location to be determined "where feasible," which aims to accommodate various property layouts while maintaining community standards.

Additionally, the board addressed concerns raised during previous public hearings about the ownership and potential sale of ADUs. The proposed language clarifies that ADUs cannot be sold separately from the primary residence, a measure intended to preserve the integrity of single-family neighborhoods.

The meeting also touched on the complexities of lot merger regulations, with board members expressing caution about adopting new bylaws until further guidance from the state is received. The consensus was to delay any decisions on this matter, acknowledging the potential for litigation and the need for clearer interpretations of the law.

As Northborough moves forward, the Planning Board's discussions reflect a broader commitment to addressing housing challenges while navigating the intricacies of local and state regulations. The upcoming town meeting will be crucial in determining the future of ADUs in the community, with residents eagerly awaiting clearer guidelines that will shape their housing options.
