Entities are grouped by a normalized name from the public record; a separate legal entity per building is common, so some portfolios span several related names. Sources: Phila. Dept. of Records (deeds), L&I (permits & violations), Dept. of Revenue (tax delinquencies), reflecting the record as of our last weekly ingest. Verify independently before relying on it.
