Completed in 1906, 45 Main St rises 12 stories over Kings. Public records put it at 162 units and 476,000 square feet of floor area, on land zoned M1-2/R8A. It is carried on the public rolls at a market value of $115M, and assessed for tax at $51.9M. In the 54 years its record reaches back, the lot has drawn 1,434 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 538 of its 1,434 records, fully 38%, fall under that one heading. Enforcement (277) and violation (254) trail well behind. 8 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 2017.

On the environmental ledger, the building posts an Energy Star score of 90, with a site energy-use intensity of 42.0 kBtu per square foot. Its operations answer for roughly 1,956 metric tons of CO2-equivalent a year.

Read together — 38% permit, 54 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$115M of Kings, written across 1,434 government filings.
