Last verified Oct 2026. All 4 values were checked cell by cell against Article 13, Table B (Dimensional Regulations) in the official Boston Zoning Code text published on Municode. Every district shown is listed in Section 3-1 of the current Code. H-2-65 and L-2-65 are not separate rows in Table B. Their FAR is the base district's Table B value, and their height is the second number in the district name, per Table B footnote (15). Lot, yard and parking rules from Table B and Articles 14-24 are not shown here. Overlay districts may further limit a parcel, including restricted parking, groundwater conservation, coastal flood resilience and Skyline districts. Source: Boston Zoning Code, Article 13.
