Property tax
$3,341/year estimated property tax
2026 taxable assessment $238,700 × 1.3998%. This is an estimate, not a bill or account balance. The City maintains payments, credits, interest, and the current amount due.
OPA has published a 2027 assessment of $205,000. It is not the 2026 billed-year value.
Payments, credits, interest, and the current amount due are maintained by the City.
OPA 1122965002026 taxable assessment equals the full assessed value.
Historical delinquency sources No current conclusion
This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.
For a purchase, refinance, or closing, request the City’s official Property Payoff statement in Tax Center under “More options.”
Where the record looks off
Conflicts in City paperwork. Flags on the data, not the property.
The assessor's condition code says vacant, yet a $303,000 sale was recorded in 2023. One side of the record is stale — condition codes come from drive-by field visits that can lag years behind.
The property, on paper
OPA physical field record.
OPA field-assessment attributes. Condition and grade are the assessor's codes, not an inspection.

Landlord and residential filings
These are property registrations or landlord filings, not businesses operating at this address.
Rental · Initial issue date Sep 28, 2023 · Terminal license date Nov 26, 2025
Rental · Initial issue date Aug 12, 2021 · Terminal license date Oct 10, 2023
Vacant Residential Property / Lot · Initial issue date Apr 5, 2018 · Terminal license date Apr 4, 2019
A license is an L&I registration, not proof that a business is open, operating today, or located at this storefront. Dates are license dates. Events are deduped by parcel, business identity, and license type, so a renewal is not shown as another opening. Other permit and filing types remain in the full source ledger.

Methodology & freshness
This report was assembled Jul 19, 2026, 12:49 AM 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.
