Completed in 1973, 420 Lefferts Ave rises 2 stories over Kings. Public records put it at 2 units and 16,800 square feet of floor area, on land zoned R6. It is carried on the public rolls at a market value of $1.4M, and assessed for tax at $623K. In the 60 years its record reaches back, the lot has drawn 90 separate government filings.

The documentary life of the address leans hard toward permit: 33 of its 90 records, fully 37%, fall under that one heading. Assignment (11) and enforcement (11) trail well behind. No 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 is benchmarked under Local Law 84, with a site energy-use intensity of 49.3 kBtu per square foot. Its operations answer for roughly 124 metric tons of CO2-equivalent a year.

Read together — 37% permit, 60 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$1.4M of Kings, written across 90 government filings.
