Pull the city's own numbers yourself. Here's the map.
The Philly Property Data Starter Kit: every public data source we use, what's in it, and the exact queries to get started.
- Direct links to the city's open-data APIs — deeds, permits, licenses, assessments — with field-by-field notes
- Copy-paste starter queries for the questions people actually ask: who owns it, what did they pay, what are they building
- The gotchas that waste your first weekend: date fields, address matching, and the $1 transfer trap
Free. One email field. No spam — just the numbers.
Everything in the kit points at official sources: City of Philadelphia open data, PA Dept. of State, FRED. We just drew the map.
