2026 taxable assessment $157,800 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $789,000; 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 1411289102026 OPA taxes $157,800 of $789,000 assessed. The assessment fields alone do not identify a program, approval date, expiration, or buyer eligibility.
See the assessment math →Applying the same rate to the billed-year full assessment. OPA's numeric split does not say when or whether the current treatment changes.
See the assessment math →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.”

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 favorable dated record
Resolve before relyingZoning approval is not the occupancy fileAppeal #ZP-2020-007308: Completed · Granted with conditions; related permit ZP-2020-007308.
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 ↗Resolve before relyingA life-safety certification appears expiredSprinkler Certification: Certified through Jun 11, 2026; Fire Alarm Certification: Certified through Jul 31, 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 ↗VerifyResidential form does not establish rental useOPA classifies the parcel as multi-family; 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 ↗VerifyFailed inspections are dated events—not the current condition2 failed, 2 passed, and 0 CLOSED investigation outcomes are in the fetched history; the latest dated visit was PASSED on Dec 1, 2020.
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 ↗VerifyA historical business license is not current operating authorityVacant Residential Property / Lot #839075: Inactive since May 2, 2022
Why it mattersA license record proves the licensed activity existed at that time. An inactive or expired license does not establish that the business still operates—or that it may legally reopen under the same use.
Verify nextIf business income matters, verify the current tenant, use registration, and active license in eCLIPSE.
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 multi-family. 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 ↗Favorable dated recordNo open violation; closed history remains relevantThe fetched record shows 0 open and 10 historical violations across 5 cases.
Why it mattersA closed case is materially better than an open one, but it does not by itself prove that every altered use, unit, or concealed condition matches today’s approvals.
Verify nextUse the closed cases to target the inspection and occupancy-file review.
Open the controlling City guidance ↗Closing file: checks no public-record summary can replace5 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 ↗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.
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
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.
Assessment/permit mismatch
The assessment jumped 404% in 2025, but no matching permit appears in the property timeline.
Evidence: assessment moved from $156,700 to $789,000 · no permit shown in 2024-2026
Limit: Not proof of unpermitted work; reassessment, corrected data, or a permit under another parcel can also explain it.
Transparent record rules, not a score or forecast. Each flag is a prompt to verify the cited records, not a prediction or allegation.
What to do with this
The record, translated into moves — what a buyer, the owner, and a landlord would each want to check next under Philadelphia's actual rules.
If you’re buying
Verify the current tax bill and exemption
The 2026 taxable assessment implies about $2,209/yr, while applying the same rate to the full assessment would imply about $11,044/yr — $8,835/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.
The multi-unit use has a zoning appeal on record
Appeal #ZP-2020-007308 was granted with conditions in 2021 for permit for the erection of an attached structure with roof deck and roof deck access structure. for use as multi family (three (3) dwelling units) household living. size and location as shown on plan.; the City row still reports status Completed. Verify the registered use and certificate of occupancy with L&I instead of assuming the use predates the code.
If you’re the landlord
If it is rented, verify the Rental License
The fetched license records do not show an active Rental License. Ownership type or a tax mailing address does not prove that tenants occupy the property; if it is rented, verify the current license and legal occupancy in eCLIPSE.
Derived from the fetched property records and linked City guidance as of 2026. Assessment treatment is not a substitute for an exemption approval, live balance, title report, license, occupancy certificate, or inspection. Informational only — not legal, tax, or investment advice.
The investment read
How this building has moved and where it's pointed: the city's assessed value (not a listing price) over 12 years, charted against its block; appreciation is that history's pace, and the 5-year figure simply extends it. Yield estimates rent-vs-price from area rents. Ask the record to dig into any number.

The assessment exemption gap
OPA's 2026 taxable assessment implies about $2,209/year. Applying the same 1.3998% rate to the full assessed value would imply ~$11,044/year — $8,835/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: ($789,000 assessed − $631,192 exempt) × 1.3998% ≈ $2,209/yr
full-assessment scenario: $789,000 × 1.3998% ≈ $11,044/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.

Methodology & freshness
This report was assembled Jul 10, 2026, 4:01 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.
