A RegWatch Dossier

90records on file

The lot at 1733 East 21 St rises 8 stories over Kings. It is carried on the public rolls at a market value of $171K, and assessed for tax at $76.9K. In the 18 years its record reaches back, the lot has drawn 90 separate government filings.

The documentary life of the address leans hard toward permit: 48 of its 90 records, fully 53%, fall under that one heading. Complaint (18) and assignment (12) trail well behind. No violations stand open against it today.

The pace is anything but even. The record runs hot early and quiets with age, with 2013 its single busiest year.

On the environmental ledger, the building is benchmarked under Local Law 84, with a site energy-use intensity of 38.6 kBtu per square foot. Its operations answer for roughly 70 metric tons of CO2-equivalent a year.

Read together — 53% permit, 18 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$171K of Kings, written across 90 government filings.
