Plumbing Permits in Suffolk County (Boston)
Plumbing building permits issued by the City of Boston, counted from the official record — totals, reported value, and the biggest plumbing projects.
Source: City of Boston open data — approved building permits issued by the Inspectional Services Department. Source last updated: October 17, 2026 · Our last pull: October 18, 2026 · Figures are as reported by the City of Boston.
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.
