Cambridge limits building heights by zoning district, with Residence A capped around 35 feet and Business and mixed-use districts allowing taller buildings up to several stories with review.
Cambridge Zoning Ordinance sets maximum building heights in feet and sometimes stories. Residence A-1 and A-2 districts typically cap principal buildings at 35 feet. Residence B and C districts allow 45 to 55 feet or more. Business and Mixed Use districts (e.g., around Kendall, Central, Harvard Squares) range from 45 feet up to 250+ feet in certain planned development districts. Height is measured from average grade to the highest point of the roof, with limited allowances for mechanical penthouses, chimneys, and rooftop solar or greenery. Buildings exceeding district limits require variance or special permit. Historic districts and view corridors add additional height constraints. Cambridge's Net Zero and Green Building ordinances affect allowable rooftop features.
