Last verified Oct 2026. All 16 values shown were checked against Section 42C-5 in the official Boston Zoning Code text published on Municode and the BPDA Article 42C PDF (bostonplans.org/getattachment/41091dfa-3b01-49a4-a970-b89db443eaf6). These limits apply to buildings and uses other than residential; a residential use follows the dimensional rules of the nearest residential district. Where a Harborpark article (42A or 42B) maps a named Waterfront Service subdistrict with its own height or FAR, that article controls. Heights are in feet. Source: Boston Zoning Code, Article 42C.
