Completed in 1931, 666 Willoughby Ave rises 6 stories over Kings. Public records put it at 48 units and 35,200 square feet of floor area, on land zoned R6B. It is carried on the public rolls at a market value of $553K, and assessed for tax at $249K. In the 61 years its record reaches back, the lot has drawn 1,080 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward violation: 490 of its 1,080 records, fully 45%, fall under that one heading. Complaint (390) and inspection (76) trail well behind. 51 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 2023.

On the environmental ledger, the building posts an Energy Star score of 31, with a site energy-use intensity of 132.4 kBtu per square foot. Its operations answer for roughly 294 metric tons of CO2-equivalent a year.

Read together — 45% violation, 61 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$553K of Kings, written across 1,080 government filings.
