What 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

Built 1950: lead rules apply

Federal law requires a lead-paint disclosure at sale for any pre-1978 home. If it will be rented, Philadelphia also requires a lead-safe or lead-free certificate before a rental license can issue.

Zoned RSA5: one household by right

Single-family rowhouse (the classic Philly row). 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.

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.
