It is carried on the public rolls at a market value of $2.1M, and assessed for tax at $959K. In the 61 years its record reaches back, the lot has drawn 594 separate government filings.

The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2018.

Read together — 37% violation, 61 years of accumulation, a parcel of New York — these scattered records compose a portrait of the address that no single page sets out to draw.

$2.1M of New York, written across 594 government filings.
