Assessment and City record timeline

Assessments are tax-roll values, not sale prices or appraisals. OPA has published a 2027 assessment of $100,000. It is not yet the billed-year tax basis.

Property tax

$1,128/year estimated property tax

2026 taxable assessment $80,600 × 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 $100,000. It is not the 2026 billed-year value.

Current City balanceCheck Tax Center

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

Exemption classificationNo exemption shown

2026 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.”

ADEBAYO & VERNELL PETER KOYIActive

Rental · Initial issue date Jan 16, 2019 · Filed expiration Jan 15, 2027

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 29, 2026, 12:29 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.

About this data & fine print

Answers are generated by an AI agent querying available City of Philadelphia open data at the moment you ask: OPA property assessments, Recorder of Deeds transfer records, L&I permits, violations & licenses, dated Dept. of Revenue tax records, Zoning Board appeals, Police incident reports, Philly311 requests, and School District of Philadelphia catchment and school data. When you explicitly request a web check, or ask about a current listing or recent news, the agent can also run a cited public-web search; those claims are labeled separately from City records.

For an explicit web search or a current listing/news question, the agent may also search the public web through OpenRouter and must link every web-derived claim. Public listing pages can be stale and are not direct or comprehensive MLS access.

Property-level tax data is historical: the delinquency snapshot is dated June 2022 and the separate detailed ledger ends in 2016. Neither shows what is owed today; verify a current balance with Philadelphia Revenue.

City data is published as-is and can lag, contain errors, or be corrected later; school performance datasets run years behind and are labeled with their school year. AI answers can contain mistakes. Verify anything that matters against the official record (property.phila.gov, atlas.phila.gov) before acting on it.

AI-generated content; informational purposes only. Answers are generated by artificial intelligence, may contain errors or omissions, are not reviewed by a person before delivery, and are not statements of fact about any person or property.
