2026 taxable assessment $902,401 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $7,754,500; it is not the 2026 billed-year value.

Question or correct this record
BlockReport can explain a discrepancy, but it cannot rewrite an official City record. Use the agency that owns the underlying fact:
Property tax
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.
A Tax Center balance is net of bills, payments, credits, interest, and adjustments. A credit—or an amount due—is not automatically “back taxes.”
OPA 8811429302026 OPA taxes $902,401 of $6,774,000 assessed. The assessment fields alone do not identify a program, approval date, expiration, or buyer eligibility.

$31,367.35 was recorded for this parcel in Philadelphia's June 2022 delinquency snapshot. That amount may have been paid, reduced, or increased since; it is not a current payoff figure.
For a purchase, refinance, or closing, request the City’s official Property Payoff statement in Tax Center under “More options.”

View supporting records →"Built 1900" is usually a placeholder
Why it mattersPhiladelphia records use 1900 as a stand-in when the real construction year was never documented. Treat the age as unknown, not as 120+ years.
View supporting records →Legal due diligence
What this record proves—and what it does not.
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.
1 resolve before relying
3 verify
Resolve before relyingZoning approval is not the occupancy fileThe record identifies more than one dwelling/use.
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 ↗VerifyResidential form does not establish rental useOPA classifies the parcel as apartments; no active Rental License row matched.
Why it mattersA multi-unit or mixed-use classification does not prove that space is currently rented. If dwelling space is rented, Philadelphia generally requires a current Rental License and related occupancy, tax, violation, and lead compliance.
Verify nextConfirm actual occupancy first; if any unit is rented, verify the license and legal unit count with L&I.
Open the controlling City guidance ↗VerifyA reduced taxable assessment is not a verified abatementOPA’s numeric assessment fields show a reduced taxable assessment; BlockReport has no official program determination for this parcel.
Why it mattersThe numeric treatment can reflect an improvement abatement or another exemption. It does not identify the ordinance, approval, start or end date, or continuation requirements after a transfer. Once OPA verifies a specific active abatement, many common programs attach the benefit to the property for the remaining term rather than ending automatically at sale, but some require a new-owner filing and continued qualifying use or tax compliance.
Verify nextObtain the OPA exemption/abatement determination and history, then underwrite the buyer’s bill from the verified program terms.
Open the controlling City guidance ↗VerifyA separate Commercial Trash account may applyOPA classifies the parcel as apartments. BlockReport does not receive a current Commercial Trash account balance.
Why it mattersPhiladelphia charges qualifying small commercial, mixed-use, and multi-unit properties that use City collection; exemptions and private collection can change applicability. A use category alone does not prove a fee is due.
Verify nextCheck the Commercial Trash account inside the date-effective Property Payoff.

Property Sales Certification
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 ↗Date-effective City Property Payoff
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 ↗Professional title and water-lien searches
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 ↗Seller-specific tax relief is not the buyer’s bill
LOOP and low-income or senior Real Estate Tax freezes depend on the qualifying owner and continued program eligibility; a buyer cannot assume the seller’s capped or frozen bill continues. A separately verified property abatement often remains with the property for its remaining term, but program-specific new-owner filing, use, and tax-compliance conditions still must be confirmed—not inferred from the reduced assessment alone.
Next: Have Revenue or OPA identify every current benefit, model the buyer’s bill without seller-specific relief, and confirm any verified abatement in writing.
Official guidance ↗Separate water-lien guidance ↗Seller disclosure and independent inspections
For a covered Pennsylvania residential transfer, obtain the statutory seller disclosure. It reports the seller’s knowledge; it is not a warranty, title search, code review, or substitute for inspections. Because OPA dates this building before 1978, separately obtain the required federal/City lead disclosures and any test results.
Next: Have the agreement and disclosure reviewed for this transaction’s coverage and exceptions.
Official 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.

Records to verify together
More than one separately dated public record deserves a current-status check.
Evidence: $31,367 appeared in the City's June 2022 delinquency snapshot · failed L&I inspection activity in 2026

Where the record looks off
Places where the city's own paperwork disagrees with itself. These are flags on the data — not problems with the property.
"Built 1900" is usually a placeholder
Philadelphia records use 1900 as a stand-in when the real construction year was never documented. Treat the age as unknown, not as 120+ years.

Methodology & freshness
This report was assembled Jul 9, 2026, 8:37 PM 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. “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.
