Cambridge Zoning Ordinance establishes front, side, and rear yard setbacks that vary by district, with dense urban districts allowing zero-lot-line development and Residence districts requiring larger yards.
The Cambridge Zoning Ordinance sets minimum yard setbacks by district. Residence A-1 and A-2 districts (primarily single/two-family) require front setbacks of 15 to 25 feet, side yards of 7.5 to 10 feet, and rear yards of 20 to 25 feet. Residence B and C districts allow smaller setbacks with multi-family density. Business and industrial districts may have zero front setbacks along commercial streets. Historic districts add additional review. Nonconforming existing structures are grandfathered but expansions require variances from the Board of Zoning Appeals. Porches, bay windows, eaves, and fire escapes may project into required yards under specific allowances in the Ordinance. Always confirm with CDD zoning staff before building.
