What this record suggests
The City file documents 3 permits touching drywall / interior finishing, plumbing. 2 carries a completed, issued, or approved status; that documents the filing, not the present quality of the work.
Unavailable when this report assembled: certifications. Unavailable does not mean no record.
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 $479,900 × 1.3998%. This is an estimate, not a bill or account balance.
OPA also publishes a 2027 assessment of $511,100; 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 3650594002026 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.”

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 27, 2026, 11:48 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: unavailable. “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.
