What this record suggests
The City file documents 9 permits touching kitchen work, electrical work, plumbing, roof work. 8 carries a completed, issued, or approved status; that documents the filing, not the present quality of the work.
Informational only — not investment advice or a consumer report (FCRA).

Property tax
The estimate, live balance, and back-tax record are different.
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 $1,789,000 × 1.3998%. This is an estimate, not a bill or account balance.
OPA also publishes a 2027 assessment of $1,889,000; 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 0531322052026 OPA removes $100,000 from the taxable assessment through the owner-occupant exemption.
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.”

Business licenses at this address Latest pull
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 24, 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 25, 2026, 8:25 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.
