New Construction Permits in Suffolk County (Boston)
New Construction building permits issued by the City of Boston, counted from the official record — totals, reported value, and the biggest new construction projects.

Coverage: this report covers building permits issued by the City of Boston (Inspectional Services Department). Suffolk County also contains Chelsea, Revere, and Winthrop, which publish their permits separately and are not in this feed, so totals here are Boston totals — labeled as such, never blended. Values are the declared project values applicants reported to the city, printed as reported; a Certificate of Occupancy restates its project's declared value, so one project's value can appear on both its building permit and its certificate.
