R8B Zoning in NYC: High-density apartment
R8B districts are high-density districts producing ten-plus story buildings, typical of dense Manhattan and downtown Brooklyn edges. Citywide, 7,362 tax lots carry a primary R8B designation.
On the average R8B lot, roughly 11% of the allowed residential floor area is unused — the raw material of a rezoning-era investment thesis. Land is expensive and assemblage-driven; underbuilt lots are rarer but each one carries large potential floor area.
