By the Numbers
How fast it's moving
Assessed-value change for the typical home. Philadelphia taxes a flat 1.3998% of value, so the bill moves with it.
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.

How the block compares
The typical home here is $242K — about 1.1× the citywide median home, and in line with the ZIP 19104 median of $242K. The same block, read against everyone else in the ZIP 19104 and across Philadelphia.

Safety & quality of life
Within 200 metres of the block over the last 12 months: 181 reported crimes (about 15 a month, 35% of them violent) and 249 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.
