That leaves 32,178 sf more floor area than stands here now, if the existing building were replaced. The largest scheme with homes and no affordability obligation holds 30,375 sf (Max Apartments).
City Planning’s PLUTO file lists a residential FAR of 3.00 for this lot, which at 10,125 sf of land is 30,375 sf. The engine’s largest residential-only scheme without an affordability obligation (Max Apartments) holds 30,375 sf, close to that simple multiplication.
Quality Housing height limit in R6A on a wide street: 75 ft (95 ft with the affordability preference). From the district’s rule set.

Floor area is zoning floor area in square feet. Highlighted: the largest scheme with homes. Income-restricted schemes (Universal Affordability Preference, AIRS senior housing) require a share or all of the homes to be affordable. Shared housing counts rooms, not apartments. Schemes that need a landmark transfer of development rights, the FRESH food store bonus or a stack of every program are left off this page; the full study shows them.
As-of-right only: what the Zoning Resolution allows without a variance, special permit or rezoning. Computed by RunEnvelope’s zoning engine on October 21, 2026 from PLUTO 26v2 lot data, in screening mode: the engine uses the City’s recorded lot area and dimensions, not a surveyed lot outline.
This is not a professional opinion, an appraisal or a statement that anything will or should be built here. Existing tenants, leases and the owner’s plans are not part of it.
Why this lot has a page: we publish pages only for lots that clear a set of data quality and headroom tests.
