Permitted floor area against what is built

Built on the lot today14,184 sf
Largest scheme with homes: UAP (City of Yes)83,917 sf

That leaves 69,733 sf more floor area than stands here now, if the existing building were replaced. The largest scheme with homes and no affordability obligation holds 67,000 sf (Max Apartments).

City Planning’s PLUTO file lists a residential FAR of 4.00 for this lot, which at 16,750 sf of land is 67,000 sf. The engine’s largest residential-only scheme without an affordability obligation (Max Apartments) holds 67,000 sf, close to that simple multiplication.

Quality Housing height limit in R7A on a wide street: 85 ft (115 ft with the affordability preference). From the district’s rule set.

  • Wide street frontage
  • E-designation on the lot
  • Irregular lot shape

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 25, 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.
