What This Means
Brookline had two provisions disapproved by the AG in June 2025 — a Floor Area Ratio cap on ADUs and a restriction tied to pre-existing nonconforming conditions. The historic district design review process remains ambiguous. With an 81% approval rate and 4 compliant provisions, the town is relatively ADU-friendly once the disapproved provisions are set aside.
