- Permit · 2010-06-14PlumbingThis permit category usually covers water, drainage, fixtures, or other plumbing work. The approved scope—not the short category—defines what was authorized, and issuance alone does not prove completion.Philadelphia construction and repair permits ↗
- Permit · 2012-10-15Major alterationA broad legacy permit work category for a substantial building alteration. It can include changed layouts, partitions, fixtures, finishes, structural work, or occupancy-related work, but only the approved scope and plans say what this permit actually authorized; separate trade permits may be required.What Philadelphia building permits can cover ↗

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.”
Where the record looks off
Conflicts in City paperwork. Flags on the data, not 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 26, 2026, 10:05 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. 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.
