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.

Food and drink at this property

1 possible-opening record signal in this 12-month window. These are classifications, not confirmed announcements.

Inference, not an opening announcement. Possible-opening classifications are inferences from public permit and license records, not confirmed opening announcements. A permit is authorization for a stated scope, not proof that work occurred or finished. A license is an L&I registration, not proof that a business is open or operating. Food and drink uses the seven exact L&I license types already used by BlockReport. The City record does not support a reliable restaurant, bar, and cafe split. License renewals do not create new events. The opening date is the earliest initial issue date for a deduped OPA parcel, normalized business identity, and license type.

Where this comes from

Methodology & freshness

This report was assembled Jul 29, 2026, 9:48 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.
