Completed in 1927, 45 Thayer St rises 5 stories over New York. Public records put it at 53 units and 34,040 square feet of floor area, on land zoned R7A. It is carried on the public rolls at a market value of $2.8M, and assessed for tax at $1.3M. In the 100 years its record reaches back, the lot has drawn 985 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 537 of its 985 records, fully 55%, fall under that one heading. Violation (270) and inspection (51) trail well behind. 22 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 2025.

On the environmental ledger, the building posts an Energy Star score of 77, with a site energy-use intensity of 116.8 kBtu per square foot. Its operations answer for roughly 242 metric tons of CO2-equivalent a year.

Read together — 55% complaint, 100 years of accumulation, a parcel of New York — these scattered records compose a portrait of the address that no single page sets out to draw.

$2.8M of New York, written across 985 government filings.
