We publish counts by ZIP code and by contractor, not a list of permits by street address. The full record for one property, with every permit, its status and its inspections, is kept by the office that issued the permits; our source here is City of Cambridge Inspectional Services permits (the city's per-type open-data permit files). Ask that permit office for a property's permit history, or search its public records by address.
For a contractor you are about to hire, open their page from the lists above to see every permit they pulled across Cambridge. Cambridge permit statistics → · How the records work in Cambridge →
Source: City of Cambridge Inspectional Services permits (the city's per-type open-data permit files). The window is October 2023 through September 2026. Each permit is placed by its property's ZIP code (the address on the permit, or the parcel's when the permit has none).
Counted: permits on homes for the 11 kinds of work we track (electrical, remodel, addition & alteration, plumbing, gas fitting, HVAC & sheet metal, roofing, solar, demolition, fire sprinkler, new construction, siding) where the record names a contractor. Not counted: commercial work, trades we don't read, and permits with no contractor (owner-pulled work). So this is not the city's count of every permit in 02140.
A ZIP code does not follow city or county lines; these count only permits in the City of Cambridge. Counts are permits, not jobs: one job can need several permits.
Nobody paid to be on this page and nobody can.
