The 2026 taxable assessment implies about $1,639/yr, while applying the same rate to the full assessment would imply about $8,197/yr — $6,558/yr more. OPA's assessment split does not establish the exemption program, expiration, or buyer eligibility. Verify the basis and live bill with OPA and Revenue.
Single-family rowhouse (the classic Philly row). Converting to a duplex or apartments needs a use variance the zoning board rarely grants — Pennsylvania courts require a physical hardship of the lot itself, and economics alone do not qualify.
OPA shows a material assessment exemption, but this record does not identify its legal basis or transfer treatment. Ask OPA for the approval history; if the current treatment ends, an eligible owner-occupant may need to apply separately for Homestead relief.

What this record suggests
The City file documents 7 permits touching bathroom work, electrical work, plumbing, roof work. 7 carries a completed, issued, or approved status; that documents the filing, not the present quality of the work.
Flags: material assessment exemption — legal basis and term unverified · historical tax ledger through 2016 with a lien entry. Informational only — not investment advice or a consumer report (FCRA).
OPA's 2026 taxable assessment implies about $1,639/year. Applying the same 1.3998% rate to the full assessed value would imply ~$8,197/year — $6,558/year more. That is a scenario, not a forecast: the assessment split alone does not identify the exemption program, approval date, expiration, transfer treatment, or live Tax Center balance.
2026: ($585,600 assessed − $468,512 exempt) × 1.3998% ≈ $1,639/yr
full-assessment scenario: $585,600 × 1.3998% ≈ $8,197/yr
The OPA amount does not prove a ten-year abatement or any other specific program. Obtain the approval history and verify the current Tax Center account; a buyer should not assume the seller's relief transfers or restarts.

This report was assembled Jul 10, 2026, 6:51 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.
