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.

A Tax Center balance is net of bills, payments, credits, interest, and adjustments. A credit—or an amount due—is not automatically “back taxes.”

This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.

Legal due diligence
These checks are triggered by this property’s actual City rows. They identify the controlling document to verify; they do not declare a use legal, a building safe, or title clear.
Why it mattersPhiladelphia says a zoning approval or Property Sales Certification can identify a use without proving that it was established under the Building Code. A change of use, unit count, exits, or fire rating can require a Building Permit and Certificate of Occupancy.
Verify nextVerify the lawful use, unit count, associated construction permits, and Certificate of Occupancy with L&I.
Open the controlling City guidance ↗Why it mattersThe aggregate currently shows zero open violations, so a historical unsafe/imminently-dangerous row is not a current hazard finding. The repair or demolition permit, final inspection, and case closure are the evidence that resolves the former designation.
Verify nextReview the Make Safe/repair permit, final inspection, and case closure.
Open the controlling City guidance ↗Why it mattersA PASSED or FAILED value applies to that inspection visit. CLOSED is a separate source status; none of the three alone proves the parent permit or violation case closed—or describes today’s condition.
Verify nextOpen the parent case/permit for each material failure and confirm its later disposition.
Open the controlling City guidance ↗Why it mattersA license record proves the licensed activity existed at that time. An inactive or expired license does not establish that the business still operates—or that it may legally reopen under the same use.
Verify nextIf business income matters, verify the current tenant, use registration, and active license in eCLIPSE.
Open the controlling City guidance ↗The seller must obtain Philadelphia’s certificate showing the base zoning, last use in the zoning record, and open violations. The City warns that it does not prove Building Code occupancy or show zoning overlays.
Next: Obtain the fresh certificate and compare it with the CO, permits, and Atlas overlays.
Official guidance ↗The Tax Center Property Payoff covers Real Estate Tax, Commercial Trash, and L&I abatement-work invoices. Philadelphia says it does not include business-tax debts or liens, water and sewer charges, or fines for code violations.
Next: Request the City statement effective through settlement; read every period and invoice.
Official guidance ↗OPA ownership, deed summaries, and a zero tax balance are not clear title. Mortgages, judgments, municipal claims, water liens, easements, heirs, and other encumbrances require separate searches.
Next: Use a Pennsylvania lawyer/title company and obtain owner’s title insurance; order the separate water search/payoff.
Official guidance ↗Separate water-lien guidance ↗Informational only—not a legal opinion, title report, code inspection, tax payoff, or substitute for a Pennsylvania lawyer, title company, inspector, or tax professional.
Rule-based groupings across this property's dated public records. Each flag shows the records that belong in the same verification step and where the inference stops.
More than one separately dated public record deserves a current-status check.
Evidence: active Vacant Commercial Property license
Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.
Transparent record rules, not a score or forecast. Each flag is a prompt to verify the cited records, not a prediction or allegation.
An empty lot: no building, just the land and its paper trail. The homeowner tools don't apply; the deed history, owner and zoning are below, and the analyst can trace what the owner holds citywide.

This report was assembled Jul 10, 2026, 6:20 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.
