Boston's Zoning Code establishes maximum building heights by zoning district, ranging from 35 feet in low-density residential areas to no height limit in parts of the Financial District. The BPDA reviews large projects and the ZBA handles height variances. FAA height restrictions also apply near Logan Airport.
Building heights in Boston are regulated by the Zoning Code with maximum heights varying significantly by district. Low-density residential zones (1F-2000, 2F) typically limit buildings to 35 feet (approximately 2.5-3 stories). Multi-family residential zones allow 45-65 feet. Neighborhood commercial districts range from 35-65 feet. Downtown and Financial District zones allow buildings up to 400+ feet, with some areas having no height maximum. Planned Development Areas (PDAs) may establish custom height limits through the BPDA approval process. The FAA imposes additional height restrictions in the flight paths near Logan Airport, requiring FAA Form 7460 (Notice of Proposed Construction) for structures over 200 feet or within certain distances of the airport. Boston's shadow regulations protect parks and public spaces from new shadows, effectively limiting building heights near Boston Common and the Public Garden. The BPDA's Article 80 review process evaluates height impacts for large and small projects. The ZBA may grant height variances for smaller projects demonstrating hardship.
Construction exceeding allowed height without approval is a zoning violation subject to ISD enforcement, potential demolition orders, and daily fines. FAA violations for unauthorized structures in flight paths carry federal penalties. Shadow violations may block project approvals.
