What This Means
Needham is a textbook restrictive town — special permit required, no detached ADUs, owner-occupancy enforced. The result: 12 ADUs in 3+ years (Green Needham, April 2023). All 4 inconsistent provisions are preempted by state law. Planning Board is working on updates but hasn’t adopted them yet.
