The makeup of the block

Every home, plotted by size and assessed value — press play and watch the block reprice from 2016 to 2027. One bubble per house (area = lot size), colored by who owns it; a gold ring marks a material assessment exemption whose legal basis is not established by the roll. Click a bubble for its report.

Safety & quality of life

Within 200 metres of the block over the last 12 months: 97 reported crimes (about 8 a month, 38% of them violent) and 170 resident 311 requests to the city. A busy commercial corridor logs far more than a quiet residential block, so read this against nearby blocks, not the citywide total.

Who really pays

Philadelphia's 1.3998% rate applies to the taxable assessment. The OPA roll shows exemptions that can make an estimate lower than the full assessed-value scenario; this chart does not identify their legal basis.

Where this comes from

Methodology & freshness

This report was assembled Jul 10, 2026, 3:05 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. “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.
