Reading this house's deeds, permits and assessments…

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

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.

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 own it

$1,399/yr may be unclaimed

This home reads owner-occupied but shows no Homestead Exemption, which removes $100,000 from the taxable assessment (worth up to $1,399/yr). Applying through the City is free and takes minutes.

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 analyst below to dig into any number.
