Philadelphia Building Permit Search & History Reports

Philadelphia's Department of Licenses & Inspections (L&I) issues all building permits within city limits. The city publishes its full L&I Permits dataset on OpenDataPhilly — over 900,000 records searchable by address, permit number, and permit type. Records cover new construction, residential renovations, demolitions, electrical, plumbing, and commercial fitouts across all 10 city council districts and 65 neighborhoods. Philadelphia's permit history is especially dense in its row-house stock: the city has more than 60,000 occupied rowhomes, and L&I records often reveal decades of incremental work — rear additions, basement conversions, and rooftop ADUs. L&I's online portal (li.phila.gov) is notoriously difficult to search by address across time; PermitReport queries the open-data API directly for complete history.

Frequently asked about Philadelphia permits.

How far back do Philadelphia L&I records go?
OpenDataPhilly's L&I Permits dataset contains records going back to the 1980s for most permit types, though data quality and completeness improve significantly after 2000.
Why is the L&I portal so hard to use?
L&I's public portal (li.phila.gov) requires knowing the exact permit number or certificate number, and doesn't support full address-history searches across time. PermitReport queries the underlying open-data API for complete address-level history.
Can unpermitted additions be detected in Philadelphia?
Yes — cross-reference L&I permit history with the Philadelphia Office of Property Assessment (OPA) records. Row-house rear additions and basement unit conversions are the most common unpermitted patterns in Philadelphia.
Does Philadelphia require contractor registration?
Yes — contractors must be licensed with the Pennsylvania Attorney General and registered with L&I. License numbers are recorded on most commercial and residential permits.
Can I get the actual permit PDF?
L&I issues physical and digital permit documents. Our Premium tier retrieves available permit documents directly from L&I records.
