What stands out
From the public recordWhat to do with this
The record, translated into moves — what a buyer, the owner, and a landlord would each want to check next under Philadelphia's actual rules.
If you’re buying
Zoned RSD3: one household by right
Single-family detached, small lot. Converting to a duplex or apartments needs a use variance the zoning board rarely grants — Pennsylvania courts require a physical hardship of the lot itself, and economics alone do not qualify.
The last transfer was not a sale
The most recent recorded deed moved for nominal consideration, within one family. That is where tangled-title problems live — budget a real title search. (Occupants untangling an inherited deed can get help from the city's Tangled Title Fund.)
If you’re the landlord
No active rental license on file
If this property is rented, Philadelphia requires a Rental License (via eCLIPSE) — without it a landlord cannot legally collect rent or evict, and tenants can withhold. Licensing needs tax clearance and no open violations.
Derived from this house's public records and the city's rules as of 2026 (abatement ordinance, Homestead, rental licensing, lead certification, L&I process, excavation protections). Informational only — not legal, tax, or investment advice.
The investment read
How this house has moved and where it's pointed: the city's assessed value (not a listing price) over 12 years, charted against its block; appreciation is that history's pace, and the 5-year figure simply extends it. Yield estimates rent-vs-price from area rents. Ask the record to dig into any number.

Methodology & freshness
City datasets are fetched live from OpenDataPhilly (phl.carto.com) and cached briefly. Dossiers re-pull automatically — on view once they're a few weeks old, plus a nightly rolling sweep — and citywide benchmarks recompute weekly. AI-written passages are generated from these records only and rejected if they state a number the record doesn't hold.
