Payments, credits, interest, and the current amount due are maintained by the City.

Historical delinquency sources Record found
$6,271.54 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot for 2018–2021. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.
$4,141.81 principal$746.39 interest$278.80 penalty$1,104.54 other charges
The snapshot’s 2022 context used $114,200 total assessment, $114,200 taxable, and $0 exempt/abated. Those historical fields can differ from today’s OPA exemption status.

What L&I has registered at this OPA parcel, newest initial license date first.
No L&I business license is on record at this address in data through Jul 25, 2026.
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, 5:01 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.
