Completed in 1927, 1921 Ave I rises 4 stories over Kings. Public records put it at 40 units and 39,830 square feet of floor area, on land zoned R7A. It is carried on the public rolls at a market value of $2.7M, and assessed for tax at $1.2M. In the 55 years its record reaches back, the lot has drawn 1,532 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward violation: 732 of its 1,532 records, fully 48%, fall under that one heading. Complaint (686) and lien (21) trail well behind. 40 violations stand open against it today.

The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2013.

On the environmental ledger, the building posts an Energy Star score of 62, with a site energy-use intensity of 76.4 kBtu per square foot. Its operations answer for roughly 196 metric tons of CO2-equivalent a year.

Read together — 48% violation, 55 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$2.7M of Kings, written across 1,532 government filings.
