Every permit in Philadelphia is public. Here's how to look one up by address — and how to read what permit activity is telling you about a block.
Philadelphia's Department of Licenses & Inspections (L&I) publishes building and zoning permits, searchable by address through the city's property atlas (atlas.phila.gov) and L&I's own systems.
Enter the property address to see permits filed against it — new construction, alterations, zoning, demolition, and more.
The permit type tells you what's being done; the description and stated valuation hint at the scale of the work.
Permits move through issued, active, and completed states, with inspections along the way. Status tells you whether work is approved, underway, or closed out.
One permit is a fact; a cluster of permits on the same block in the same quarter is a signal. Reading permit activity by area is where the real intelligence is.
BuildSignal aggregates L&I permit filings by area, so instead of checking addresses one at a time you can see where construction and investment are accelerating across a neighborhood — with every figure traceable to the underlying permits.

It reflects L&I's own published data, which updates as the department processes filings.
A permit authorizes work; a violation flags a code problem. They're separate L&I records.
Yes — that block- and area-level view is what BuildSignal is built for.
