The crux of the discussion was whether the current septic system, designed in 1981, meets modern local regulations, specifically Lakeville Regulation 2.1, which necessitates a septic system reassessment and possibly an upgrade when structural modifications occur. The Board deliberated if the existing system, which was designed for three bedrooms but calculated for a lesser capacity by current standards, would suffice or if an upgrade would be necessary.

Several members expressed comfort with maintaining the property as a three-bedroom dwelling, noting that previous Title V inspections confirmed this count. However, they flagged that the system didn’t meet the 330 gallons per day requirement under the current regulation, which would typically necessitate a waiver or an upgrade. The Board also considered whether the garage conversion might classify the space as an accessory dwelling unit (ADU), which would require additional permitting processes.
