2026 taxable assessment $480,200 × 1.3998%. Estimate—not a bill or account balance.
OPA also publishes a 2027 assessment of $467,100; 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 0215733002026 taxable assessment equals the full assessed value.
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.”

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 1915: 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.
If you own it
4 open violations: the clock matters
Most L&I appeals must be filed within 30 days; unsafe or imminently dangerous orders can carry a shorter deadline. Unresolved notices can lead to fees, court enforcement, City abatement work, and liens. Read the dated notice and verify its current status with L&I.
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.

Run the numbers
What owning 1139 S 11th St takes, at your price and your rate. Taxes start with an annual estimate from the City’s taxable assessment, not a current bill or balance; rent starts at the area median. Assessed value is not an asking price — set the price slider to the real one.
When this house last sold (2025) a 30-year mortgage ran about 6.6% — Freddie Mac's average that year.

Methodology & freshness
This report was assembled Jul 10, 2026, 4:03 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.
