Source: City of Philadelphia, Licenses and Inspections Building and Zoning Permits, 2007 to present (OpenDataPhilly; Carto table permits), read 19 Oct 2026. We count permits issued October 2024 through September 2026; denied and withdrawn permits are left out.
Residential permits the City of Philadelphia Department of Licenses and Inspections (L&I) issues inside the city, which is also Philadelphia County: building, plumbing, electrical, mechanical, EZ minor-work, demolition and solar permits for homes. Commercial permits, zoning and use permits, excavation and site permits, certificates of occupancy and event permits in the same file are not counted. Suburbs in Bucks, Montgomery and Delaware counties 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 →
