Philadelphia property record
One unified property record from Philadelphia's L&I data — pulled live from Eclipse (authoritative for current state) and cross-checked against Carto (historical mirror). Flags drift between the two. Decodes status semantics. Resolves your council district and councilmember. Surfaces what the public data doesn't tell you.

What 4PHILLY can't tell you — and why.

This app queries data the city already publishes. Where it falls short, the limitation is a city data gap, a policy decision, or a technical constraint of running without a server. Future versions will try to address each of these.
