What we hold for Philadelphia, PA
Last updated
How the scoring works is the same in every market we cover. This page is about Philadelphia, PA specifically: which datasets we use, who publishes them, and what they cannot tell you.
Where the data comes from
All property data on this site is public record. For Philadelphia, PA that means:
- Parcels, owners, mailing addresses and sale history — City of Philadelphia Office of Property Assessment, Philadelphia Properties and Assessment History (opa_properties_public).
- Housing-code violations — City of Philadelphia Department of Licenses and Inspections, Licenses and Inspections Code Violations.
- Rental licences and unit counts — City of Philadelphia Department of Licenses and Inspections, Business Licenses (licensetype = Rental).
Every record we show carries the source it came from and the date we retrieved it. We never assert that a person or company owns a property; we say what the records indicate, and link to them.
What this data cannot tell you
- Unit counts come from rental licences, not the assessment file, which publishes none. A property with no current rental licence has no denominator, so its Public Record Score is withheld rather than estimated.
- Philadelphia publishes whether a violation was resolved, and often the date. Records here therefore say “confirmed still open” or “closed” rather than the weaker “on record” we must use in Washington, DC.
- Owner names are the assessment file's, which lists the party of record. A property held through a trust or an agent may name that party rather than the beneficial owner.
Local rules that change what we say
We make no rent-regulation claims in Philadelphia, PA. Nothing in the local law attaches a status to a missing registration in the way it does in some other markets, and asserting one would be a false statement about the law.
Parcels here are identified by OPA account number, which is the identifier shown on property pages and used to link our records back to the source.
