4PHILLY

4PHILLY is a free, open-source, independent tenant tool that lets Philadelphia renters check any address against the City's public records, open code violations, rental-license status, and 311 complaints, before signing a lease or when fighting a landlord.

Philadelphia

Built by an independent developer from Philadelphia's own open data (L&I, 311, property assessment), 4PHILLY turns scattered public records into a plain-language "4P Score" and record for any address, and even drafts 311 complaints and Right-to-Know requests for tenants. It also exposes a 60-day window in which an expired, rent-barring rental license stays invisible on the City's official map tools, shifting a small piece of informational power back toward renters.
