Source: City of Madison Development Services Center, Permit Reports (Construction Summary and Electrical, Plumbing and HVAC permit reports, CSV export), read 19 Oct 2026. We count permits issued October 2024 through September 2026; denied and withdrawn permits are left out. The city's permit reports have no status and no final inspection date, so no finished share is shown.
Building permits (new homes and buildings, alterations and repairs, re-roofs, decks, garages, raze permits) and electrical, plumbing and HVAC permits issued by the City of Madison Building Inspection Division for property in the city. Permits issued by the surrounding towns and villages (Fitchburg, Middleton, Monona, Sun Prairie, Verona and the rest) and by Dane County are not in these reports.
Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
