That leaves 30,221 sf more floor area than stands here now, if the existing building were replaced.

City Planning’s PLUTO file lists a residential FAR of 0.75 for this lot, which at 37,740 sf of land is 28,305 sf. The engine’s largest residential-only scheme without an affordability obligation (Max Apartments) holds 28,305 sf, close to that simple multiplication.

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.

What these numbers are

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.

What a full study checks

  • ■The actual lot outline, street frontages and yards, not PLUTO's recorded dimensions
  • ■Easements, restrictive declarations and zoning lot agreements on record
  • ■Landmark, waterfront and flood rules that apply to the specific building
  • ■Height, setback and floor-by-floor massing, with floor plans
  • ■Unit count, parking and the affordability program terms

Why this lot has a page: we publish pages only for lots that clear a set of data quality and headroom tests.
