R1-2A Zoning in NYC: Single-family detached
R1-2A districts are the lowest-density residential districts in New York City, limited to detached single-family homes on large lots, found in garden-suburb pockets. Citywide, 1,544 tax lots carry a primary R1-2A designation.
On the average R1-2A lot, roughly 40% of the allowed residential floor area is unused — the raw material of a rezoning-era investment thesis. Value is driven by land and the existing house; development upside is limited, though City of Yes ADU allowances opened new possibilities on many lots.
