Completed in 1931, 450 Johnson Ave rises 2 stories over Kings. Public records put it at 3 units and 32,500 square feet of floor area, on land zoned M1-2. It is carried on the public rolls at a market value of $3.7M, and assessed for tax at $1.7M. In the 45 years its record reaches back, the lot has drawn 65 separate government filings.

The documentary life of the address leans hard toward sale: 13 of its 65 records, fully 20%, fall under that one heading. Permit (12) and enforcement (12) trail well behind. 4 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 1981.

On the environmental ledger, the building posts an Energy Star score of 94, with a site energy-use intensity of 31.9 kBtu per square foot. Its operations answer for roughly 60 metric tons of CO2-equivalent a year.

Read together — 20% sale, 45 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$3.7M of Kings, written across 65 government filings.
