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
Today's $1,542/yr reflects a 10-year abatement. It steps up every year and reaches about $3,919/yr in 2033 — $2,377/yr more. Price the full bill, not the current one.
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.
If you own it
An abated home cannot also take the Homestead Exemption. From 2033 it can — knocking about $1,400/yr off the full bill.
Excavation deeper than 5 feet, or within 10 feet of an adjacent structure, legally requires the developer to survey neighboring homes first and give owners 10 days' written notice. Insist on the pre-construction survey — it is your evidence if cracks appear.
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.

Flags: tax-abated — the bill lags real value. Informational only — not investment advice or a consumer report (FCRA).
The abatement clock
This house pays about $1,542/yr under a 10-year tax abatement that steps down every year. In 2033 the bill reaches its full ~$3,919/yr — a step up of $2,377/yr, 6 assessment years out. Drag the slider.
now: ($280,000 assessed − $169,841 abated) × 1.3998% ≈ $1,542/yr
2033: $280,000 assessed × 1.3998% ≈ $3,919/yr
The abated slice shrinks ~10% a year (post-2022 program, started 2023) — reassessments move both lines. After expiry an owner-occupant can claim the Homestead Exemption (~$1,400/yr off); an abated home can't hold both.

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; the masthead date is when this page's records were last pulled. AI-written passages are generated from these records only and rejected if they state a number the record doesn't hold.
