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.
2026 taxable assessment $264,100 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $245,600; it is not the 2026 billed-year value.
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 3631035002026 taxable assessment equals the full assessed value.
This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.

View supporting records →The record, translated into moves — what a buyer, the owner, and a landlord would each want to check next under Philadelphia's actual rules.
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.
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 fetched license records do not show an active Rental License. Ownership type or a tax mailing address does not prove that tenants occupy the property; if it is rented, verify the current license and legal occupancy in eCLIPSE.
Derived from the fetched property records and linked City guidance as of 2026. Assessment treatment is not a substitute for an exemption approval, live balance, title report, license, occupancy certificate, or inspection. Informational only — not legal, tax, or investment advice.

What this record suggests
The City file documents 3 permits touching kitchen work, electrical work, plumbing, roof work. Status needs checking in the official file; that documents the filing, not the present quality of the work.
Flags: 1 zoning/board appeal on record. Informational only — not investment advice or a consumer report (FCRA).
The city assessor's field record — the physical spec sheet behind the assessed number.
OPA field-assessment attributes. Condition and grade are the assessor's codes, not an inspection.

This report was assembled Jul 10, 2026, 9:06 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. For this property: Permits: queried · Violations: queried · Investigations: queried · Appeals: queried · Licenses: queried · Building certifications: queried. “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.
