$1,203/year estimated property tax

2026 taxable assessment $85,907 × 1.3998%. This is an estimate, not a bill or account balance. The City maintains payments, credits, interest, and the current amount due.

OPA has published a 2027 assessment of $397,700. It is not the 2026 billed-year value.

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

Historical delinquency sources Record found

$4.94 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot for 2020–2021. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.

The snapshot’s 2022 context used $10,500 total assessment, $10,500 taxable, and $0 exempt/abated. Those historical fields can differ from today’s OPA exemption status.

A separate historical parcel ledger ending in 2016 records $2,533.15 and a lien entry. It is shown as historical context only.

The assessment exemption gap

OPA's 2026 roll shows a partial assessment exemption. The annual difference is measurable; the reason for it and what happens after a sale are not established here.

Using OPA's taxable amount ~$1,203/year

$85,907 taxable basis

Difference to verify+$4,102/year
If the full assessment were taxable ~$5,305/year

$379,000 scenario basis

The assessment roll does not identify
  • Legal basis or program
  • Approval or expiration date
  • Treatment after a sale
  • Current Tax Center balance
Show the assessment math 2026: ($379,000 assessed − $293,093 exempt) × 1.3998% ≈ $1,203/year Full-assessment scenario: $379,000 × 1.3998% ≈ $5,305/year

Do not treat the full-assessment scenario as inevitable or assume the current relief transfers. Obtain the approval history and verify the live Tax Center account before relying on either number.

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.

Where this comes from

Methodology & freshness

This report was assembled Jul 25, 2026, 8:32 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.
