Completed in 2016, 340 Neptune Ave rises 8 stories over Kings. Public records put it at 20 units and 18,951 square feet of floor area, on land zoned R6. It is carried on the public rolls at a market value of $3.7M, and assessed for tax at $1.6M. In the 45 years its record reaches back, the lot has drawn 540 separate government filings.

The documentary life of the address leans hard toward enforcement: 228 of its 540 records, fully 42%, fall under that one heading. Violation (112) and complaint (82) trail well behind. 6 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 10, with a site energy-use intensity of 56.8 kBtu per square foot. Its operations answer for roughly 117 metric tons of CO2-equivalent a year.

Read together — 42% enforcement, 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 540 government filings.
