The Hubbardston Planning Board has made significant strides in updating local regulations regarding accessory dwelling units (ADUs), a move aimed at enhancing housing options in the community. During a recent meeting, board members discussed proposed changes that would allow for more flexibility in the size and permitting of ADUs, which are secondary housing units located on the same lot as a primary residence.

One of the key points of discussion was the maximum size of an ADU. The board proposed that the size should be the lesser of half the gross floor area of the principal dwelling or 1,000 square feet. For example, a homeowner with an 1,800 square foot house could build an ADU of up to 900 square feet. This approach aligns with state regulations, which permit localities to adopt less restrictive measures but not more stringent ones. The board expressed confidence that this proposal would pass with a two-thirds majority at the upcoming town meeting, as it reflects a less restrictive stance compared to state guidelines.

Another important aspect of the discussion involved the permitting process for ADUs. The board clarified that homeowners wishing to create an ADU must first obtain a building permit for any renovations to the primary dwelling. This ensures that the permits are tracked separately, which is crucial for compliance with state reporting requirements.

The board also addressed the need for adequate water and wastewater disposal systems for both the primary dwelling and the ADU. This requirement aligns with existing regulations and allows for future adjustments as state laws evolve.

Parking requirements were another focal point, with the board proposing that one additional parking space be required for ADUs located more than half a mile from public transit. This measure aims to balance the need for parking with the accessibility of public transportation.

Lastly, the board confirmed that ADUs would be permitted in all residential zoning districts, expanding housing options throughout Hubbardston. This change is in line with new state laws that encourage the development of ADUs in areas designated for single-family homes.

As the board prepares to submit these proposed changes to the attorney general's office for preliminary review, they remain committed to fostering a housing environment that meets the needs of Hubbardston residents. The upcoming town meeting will be a crucial step in determining the future of ADUs in the community, with potential implications for housing availability and local development.
