2026 taxable assessment $53,200 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $66,200; it is not the 2026 billed-year value.

Question or correct this record
BlockReport can explain a discrepancy, but it cannot rewrite an official City record. Use the agency that owns the underlying fact:
Property tax
The estimate, live balance, and back-tax record are different.
BlockReport can calculate the annual tax from the City’s taxable assessment. Payments, credits, interest, and a current amount due live separately in Philadelphia Tax Center.
A Tax Center balance is net of bills, payments, credits, interest, and adjustments. A credit—or an amount due—is not automatically “back taxes.”
OPA 5921274002026 taxable assessment equals the full assessed value.

View supporting records →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 1915: 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.
The last transfer used nominal consideration
The latest deed records $100 or less. That is not a usable market-sale price and can reflect a family, estate, gift, correction, or entity transfer. Inspect the deed and order a title search rather than inferring the relationship or chain.
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.
8 open violations: the clock matters
Most L&I appeals must be filed within 30 days; unsafe or imminently dangerous orders can carry a shorter deadline. Unresolved notices can lead to fees, court enforcement, City abatement work, and liens. Read the dated notice and verify its current status with L&I.
$42,053 in the historical tax ledger through 2016
Historical context only, not a current payoff figure; that ledger also contains a lien entry. Verify today's balance and lien status directly with Philadelphia Revenue before relying on it.

Methodology & freshness
This report was assembled Jul 9, 2026, 3:54 PM ET. Available City datasets are queried from OpenDataPhilly (phl.carto.com) and the cited City ArcGIS feeds; record queries paginate rather than silently taking a first page. “Unavailable” means the source query failed or was not supplied, not “no record.” Reports re-pull on view after seven days and on an overnight rolling schedule; citywide benchmarks recompute weekly. Source dates still govern: the parcel-level tax-delinquency snapshot is June 2022 and the separate detailed tax ledger ends in 2016, so neither establishes today’s balance. The live balance and date-effective payoff must be verified in Tax Center. AI-written passages are grounded in the assembled record and rejected if they state a number the record does not hold.
