2026 taxable assessment $180,900 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $284,900; 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 0111687002026 OPA removes $100,000 from the taxable assessment through the owner-occupant exemption.
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 mattersBought for $165K in 2010. Owner pulled a mechanical permit in 2014.
View supporting records →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
Built 1905: lead rules apply
Federal law requires a lead-paint disclosure at sale for any pre-1978 home. If it will be rented, Philadelphia also requires a lead-safe or lead-free certificate before a rental license can issue.
Zoned RSA5: one household by right
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.
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 house 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.

Free record guide
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 7 on this property
This property’s file includes BP_ALTER, ZP_ZONING, BP_ADDITON, BP_ADMINST 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
L&I enforcement records can include warnings, notices, orders, inspections, and later resolution activity. A closed visit is still a historical record; it is not a missing event.
How L&I code enforcement works ↗City violation and order types ↗Informational only — not investment advice or a consumer report (FCRA).

Methodology & freshness
This report was assembled Jul 10, 2026, 9:03 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.
