It is carried on the public rolls at a market value of $53.0M, and assessed for tax at $23.9M. In the 34 years its record reaches back, the lot has drawn 271 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 2025.

On the environmental ledger, the building is benchmarked under Local Law 84, with a site energy-use intensity of 80.1 kBtu per square foot. Its operations answer for roughly 629 metric tons of CO2-equivalent a year.

Read together — 54% permit, 34 years of accumulation, a parcel of Richmond — these scattered records compose a portrait of the address that no single page sets out to draw.

$53.0M of Richmond, written across 271 government filings.
