Property tax
$7,710/year estimated property tax
2026 taxable assessment $550,800 × 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 $499,300. It is not the 2026 billed-year value.
Payments, credits, interest, and the current amount due are maintained by the City.
OPA 6021641002026 taxable assessment equals the full assessed value.
Historical delinquency sources Record found
$210.69 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot for 2015. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.

The snapshot’s 2022 context used $290,100 total assessment, $290,100 taxable, and $0 exempt/abated. Those historical fields can differ from today’s OPA exemption status.
A separate historical parcel ledger ending in 2016 records $186.99 and a lien entry. It is shown as historical context only.

Rental · Initial issue date Apr 12, 2007 · Terminal license date Dec 22, 2012
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 26, 2026, 1:37 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.
