Permitted floor area against what is built

Built on the lot today19,500 sf
Largest scheme with homes: AIRS Senior Housing (100% Affordable)72,000 sf

That leaves 52,500 sf more floor area than stands here now, if the existing building were replaced. The largest scheme with homes and no affordability obligation holds 60,200 sf (Max Apartments).

City Planning’s PLUTO file lists a residential FAR of 6.02 for this lot, which at 10,000 sf of land is 60,200 sf. The engine’s largest residential-only scheme without an affordability obligation (Max Apartments) holds 60,200 sf, close to that simple multiplication.

Quality Housing height limit in R8X on a wide street: 155 ft (175 ft with the affordability preference). From the district’s rule set.

  • Wide street frontage
  • Mandatory Inclusionary Housing area
  • FRESH food store zone
  • E-designation on the lot

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 23, 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.
