571 Bay Street, Staten Island 10304 is a 23,323 square foot lot zoned C4-2. RunEnvelope’s engine finds an as-of-right scheme with homes of 90,960 sf (UAP (City of Yes)), against 4,800 sf built on the lot today.
That leaves 86,160 sf more floor area than stands here now, if the existing building were replaced. The largest scheme with homes and no affordability obligation holds 87,052 sf (Residential + Community Facility).
City Planning’s PLUTO file lists a residential FAR of 2.43 for this lot, which at 23,323 sf of land is 56,675 sf. The engine’s largest residential-only scheme without an affordability obligation (Max Apartments) holds 69,969 sf, 23% more than that simple multiplication suggests.

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 24, 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.
