Data through September 2026 · updated 18 Oct 2026
23,383 building permits were issued in Buffalo from October 2024 to September 2026, about 11,692 a year. Electrical permits lead with 6,358, then plumbing (5,186) and HVAC (3,413). 77% were for homes. The city's file names contractors, but we name a firm only where the permit's contractor licence number is on the city's licensed contractors list, and we have not checked those licences or the work, so we only count permits per firm and don't rate or rank them: these pages show what was built, where and when.
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.
The permit file can't tell you who does good work. Ask for the contractor's license number and look it up at the City of Buffalo licensed contractors list, then ask the city whether they pulled the permit for your job.
Permits issued October 2024 through September 2026, every kind of work with 100 or more. Last 12 months is Oct 2025–Sep 2026. Homes is the share issued as residential permits.

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 We count permits issued October 2024 through September 2026; denied and withdrawn permits are left out.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.
