Ordinance Consistency
Worcester’s ordinance is mostly builder-friendly — no site plan review, no parking restrictions, by-right through building permit. The two issues are owner-occupancy (which the city council voted 9-2 to keep, per This Week in Worcester, December 2023) and the 2-bedroom cap (which mirrors a provision the AG struck down in Leicester).
