This parcel did not match the June 2022 delinquency snapshot. That absence does not confirm the account is current today.

From the public recordWhat the record is signaling
Early patterns mined across this property's dated public records. Each flag shows what triggered it and where the inference stops.
Public-record pressure
More than one public record deserves a current-status check.
Evidence: 1 open L&I violation · a lien number appears in the historical tax ledger through 2016 · failed L&I inspection activity in 2021, 2022, 2023, 2024, 2026
Limit: A screening signal, not a foreclosure prediction. Tax entries are historical and must be verified with Philadelphia Revenue.
Recent transition activity
The property has an unusually active paper trail worth monitoring for the next permit, inspection, deed, or listing.
Evidence: 4 permit events since 2023 · demolition activity since 2023
Limit: Record activity alone does not establish that a sale or redevelopment is planned.
Transparent record rules, not a machine-learning forecast. A signal is a prompt to verify the cited record, not a prediction or allegation.

An empty lot: no building, just the land and its paper trail. The homeowner tools don't apply; the deed history, owner and zoning are below, and the analyst can trace what the owner holds citywide.

Methodology & freshness
Available City datasets are queried from OpenDataPhilly (phl.carto.com), then reports are cached and refreshed on a rolling schedule. Source dates vary: the parcel-level tax-delinquency snapshot is June 2022 and the separate detailed tax ledger ends in 2016, so neither establishes today’s balance. Other dossiers re-pull on view once stale, and citywide benchmarks recompute weekly. AI-written passages are generated from these records only and rejected if they state a number the record doesn't hold.
