Source: City of Buffalo Open Data, Permits dataset 9p2d-f3yt, read 18 Oct 2026. We count permits issued October 2024 through September 2026; denied and withdrawn permits are left out. The city's public file has no permit status and no final inspection date, only an expiration date, so no finished share is shown.
Building, electrical, plumbing, heating, demolition and other construction permits the City of Buffalo Department of Permit and Inspection Services issues inside city limits. Special use and change of use permits in the same file are not counted. Buffalo's suburbs (Amherst, Cheektowaga, Tonawanda and the rest of Erie County) run their own permit offices and are not in this file.
Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
