2026 taxable assessment $0 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $6,447,600; 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 7822074052026 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 recordImproved
Why it mattersOwner pulled a addition and/or alteration permit in 2024.
View supporting records →Assessment frozen for a decade
Why it mattersThe assessed value hasn't moved once in 10 years of records while the city around it repriced. That usually means the parcel is falling through the reassessment process, not that its value is flat.

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.
2 resolve before relying
4 verify
Resolve before relying7 open L&I violations61 violation rows are retained in the City ledger.
Why it mattersOpen notices can accrue fees, block permits or license renewal, and move to court or collection. Standard initial notices generally have a 30-day appeal window; unsafe or imminently-dangerous notices have a much shorter window.
Verify nextRead the notice—not only the summary status—and confirm reinspection, fees, and appeal posture with L&I.
Open the controlling City guidance ↗Resolve before relyingA life-safety certification appears expiredEmergency and Standby Power Systems Certification: Certified through Dec 27, 2024; Fire Alarm Certification: Certified through Jan 11, 2026
Why it mattersFire-protection certifications apply to the named system and inspection period only; they are not a whole-building safety certificate. Philadelphia generally requires annual sprinkler, standpipe, fire-alarm, special-hazard, and emergency-power inspections where those systems exist.
Verify nextRequest the correction/reinspection and current filed certificate.
Open the controlling City guidance ↗VerifyFailed inspections are dated events—not the current condition12 failed, 9 passed, and 0 CLOSED investigation outcomes are in the fetched history; the latest dated visit was FAILED on Jun 8, 2026.
Why it mattersA PASSED or FAILED value applies to that inspection visit. CLOSED is a separate source status; none of the three alone proves the parent permit or violation case closed—or describes today’s condition.
Verify nextOpen the parent case/permit for each material failure and confirm its later disposition.
Open the controlling City guidance ↗VerifyThe latest nominal transfer is not a market sale—or a title opinionThe latest deed in the assembled record moved for nominal consideration.
Why it mattersA $1 or nominal deed can be a valid family, estate, or entity transfer. It does not establish a sale price, clear title, or by itself prove a tangled title.
Verify nextRead the recorded deed and have the title search confirm every grantor, grantee, estate/probate step, lien, and authority to sell.
Open the controlling City guidance ↗VerifyOPA shows a full exemption; its legal basis is unverifiedOPA currently marks the land and building assessment fully tax-exempt; BlockReport does not receive the exemption determination or basis.
Why it mattersFull OPA exemptions can have different legal bases, including government, religious, charitable/institutional, veteran, or other treatment. The current owner/use record is not a buyer’s tax forecast.
Verify nextConfirm the exact exemption basis, buyer eligibility, and next tax-year treatment directly with OPA.
Open the controlling City guidance ↗VerifyA separate Commercial Trash account may applyOPA classifies the parcel as commercial. 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.
Open the controlling City guidance ↗Closing file: checks no public-record summary can replace3 documents/searches to assign before settlement
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 ↗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
Rule-based groupings across this property's dated public records. Each flag shows the records that belong in the same verification step and where the inference stops.
Records to verify together
More than one separately dated public record deserves a current-status check.
Evidence: 7 open L&I violations · failed L&I inspection activity in 2021, 2022
Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.
Transparent record rules, not a score or forecast. Each flag is a prompt to verify the cited records, not a prediction or allegation.
Not a houseProperty report
This is a school, 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.

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.
Assessment frozen for a decade
The assessed value hasn't moved once in 10 years of records while the city around it repriced. That usually means the parcel is falling through the reassessment process, not that its value is flat.

Methodology & freshness
This report was assembled Jul 10, 2026, 2:31 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.
