The Lakeville Planning Board voted Thursday to continue the site-plan public hearing for an accessory dwelling unit proposed at 225 County Street to July 10, 2025.

The application, submitted in support of homeowner William Fuller, seeks approval for a 900-square-foot ADU with an attached garage on the upper level and an additional garage underneath, and a deck facing the pond. Jamie Bissonette of Zenith Consulting Engineers, representing the applicant, described the ADU as sited “pretty much onto the side of the garage” and said utilities would tie into the existing well and septic. Bissonette said the project team has conferred with conservation and with the Board of Health on plumbing and septic questions.

The board flagged a set of technical items for the applicant to supply before the continued hearing. Planning staff asked the applicant to provide existing and proposed lot-coverage percentages and the existing and proposed living-area square footage. The board also asked staff to share any fire-department concerns with the applicant after the fire chief raised a potential egress issue: the property’s stone-wall entrance and gate are shown with a 10-foot opening while the department’s apparatus width was described in meeting materials as 9 feet 6 inches.

Bissonette told the board that, in his view and after consulting with building-department staff, garage areas are excluded from gross floor-area calculations and that the ADU metric focuses on living area. “In the in the regulation itself, it kinda goes into it actually excludes garage area from gross floor area,” Bissonette said. Planning staff (Nate) will confirm whether the proposed accessory buildings trigger a special-permit review through the Zoning Board of Appeals; the board was told that if the building-department determines the accessory structures push the property beyond dimensional or coverage limits, a separate special-permit application to the ZBA would be required.

On wastewater, Bissonette described a plan to install a grinder-pump lift station in the ADU basement that would pump into the existing house plumbing; he said the team met with Ed from the Board of Health. To limit additional septic load, the applicant plans to eliminate a bedroom in the primary dwelling. Bissonette said a Title 5 inspection would be part of the process.

Board members also asked whether the ADU would receive separate electric service or meter; Bissonette said the applicant will apply through the building department and that meter configuration has not been finalized. The board noted that the new structure will require a separate street address and that the town’s GIS office should be notified when permits are pulled.

The board opened the public hearing and, after clarifying outstanding materials and receiving assurances that staff would circulate the fire-department memo to the applicant, voted to continue the hearing to July 10, 2025. The board directed the applicant to provide the requested lot-coverage and square-footage figures and for staff to confirm whether a ZBA special permit will be required if accessory structures change coverage calculations.

The continuation means the board will review the updated plan set, any building-department determinations on accessory area, and any additional comments from the fire department and the Board of Health at the July 10 meeting.
