filtered to the ZIP you enter. Violations and licenses are matched by OPA account number; 311
complaints are matched by ZIP code on the complaint record (the 311 dataset has no OPA number, so
it is joined by location, not parcel ID).
An OPA number (Office of Property Assessment account number) is the city's unique ID for a
single parcel of land — like a fingerprint for the property. Every property in Philadelphia has one.
Why it can beat the address: one street address can cover several parcels (a corner lot, a
subdivided building, a condo with many units), and the same address can be written many ways
(“1500 Market St” vs the city's official “1500-16 MARKET ST”). The OPA number points at exactly one
parcel with no ambiguity, so if you have it, the lookup is guaranteed to hit the right record.
Don't have it? Just use the address — that's what most people do, and this tool figures out the
matching OPA for you. You can find a property's OPA number on
Atlas or a tax bill.

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.
Every apartment in Philadelphia carries a paper trail most landlords would rather you never read. 4philly pulls it into the open — free, in seconds, straight from the City's own Licenses & Inspections and rental-license records — so the power isn't all on their side of the lease.
Check the apartment you're about to call home — or any Philadelphia address you're thinking of renting. See open code violations, whether the building's rental license is active, and the 311 complaints past tenants filed. Fresh paint and a friendly tour hide a lot; the City's record doesn't. Walk in knowing exactly what you'd be signing up for.
Repairs ignored, rental license lapsed, deposit games? Pull the same public records the City relies on and turn “he said / she said” into documented facts — ready to bring to your landlord, a housing attorney, Philadelphia L&I, or your City Council member.
Built for Philadelphia renters and tenants. No account, no cost, no catch — just the truth about your address before you sign or when you need to fight back.

Not every Philadelphia rental has a problem record. Pick a ZIP code to see how many properties currently hold an active rental license with zero open L&I violations and no open 311 complaints — queried live from the City's own open data — plus the three covering the most rental units.
Live point-in-time query of Philadelphia's public rental-license, violation, and 311 data (phl.carto.com, refreshed daily by the City). 311 complaints are matched by address text — the 311 feed carries no parcel ID — so that filter is approximate. A listing here is not an endorsement of any property or owner; records change daily. Verify anything that matters at atlas.phila.gov.
Every Philadelphia ZIP code, laid out like the city grid. 4philly checks open code violations, rental license status, and 311 complaints across all of them — pick yours and scan the whole neighborhood.
