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.

Estimated annual Real Estate Tax$0/year

2026 taxable assessment $0 × 1.3998%. Estimate—not a bill or account balance.

OPA also publishes a 2027 assessment of $122,595,700; it is not the 2026 billed-year value.

Official current account balanceCheck live

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

Open Philadelphia Tax Center →Choose “View period balance” to see the tax year and any credit, interest, or delinquency.
Exemption classificationFull assessment exemption shown

2026 OPA shows a zero or de minimis taxable assessment. The open assessment split does not establish the exemption's legal basis, continuing eligibility, or treatment after a transfer.

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.”

What stands out

From the public record

The property record, over time

Every dated deed, permit, inspection, license, violation, certification, and appeal is placed on the City’s annual assessment line. Select a point to read what happened; the line is an assessment history—not a sale-price chart or appraisal. OPA has also published a 2027 assessment of $122,595,700; it is not yet the billed-year tax basis.

Highlight
Not a houseProperty report

This is a museum, not a home, and OPA shows a full or near-full assessment exemption whose basis must be verified. A $0 assessment-based tax estimate does not prove the live Tax Center account has no prior-period balance or other charges. Homeowner investment tools are hidden; the assembled public-source record remains below.

What this record suggests

The City file documents 5 permits touching electrical work, plumbing. 5 carries a completed, issued, or approved status; that documents the filing, not the present quality of the work.

How Philadelphia’s property system works

These explainers are free because the record only helps if you know what it can—and cannot—prove. Use the linked City guidance for the controlling rule.

Permits and inspections 5 on this property

This property’s file includes EP_ELECTRL, BP_FIRESUP, OPS, PP_PLUMBNG permit records. A permit documents authorized scope and a City process; it is not by itself proof that every described improvement was completed, remains in place, or meets today’s condition expectations.

L&I inspections are scheduled at defined stages; final inspection and required certifications are separate steps in closing out applicable work.

How construction and repair permits work ↗See City inspection stages by permit type ↗
Assessments and taxes

The OPA assessment is the City’s value on the tax roll—not an asking price, appraisal, or live account balance. The taxable assessment can differ from the full assessment because the City roll records exemptions or other treatment; the report keeps those fields separate.

Your annual estimate uses the taxable assessment. Payments, credits, interest, and the amount due are maintained separately in Tax Center.

How the Office of Property Assessment works ↗Philadelphia property-tax guidance ↗
Violations, cases, and status check current status

An open row is a dated City status, not a diagnosis of current condition or a conclusion about the property. Read the case, notice, and any subsequent inspection together, then verify the live file.

Where this comes from
Methodology & freshness

This report was assembled Jul 10, 2026, 7:16 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.
