450 Front Street, Staten Island 10304 is a 17,973 square foot lot zoned C4-2A. RunEnvelope’s engine finds an as-of-right scheme with homes of 64,231 sf (UAP (City of Yes)), against 17,500 sf built on the lot today.
That leaves 46,731 sf more floor area than stands here now, if the existing building were replaced. The largest scheme with homes and no affordability obligation holds 35,946 sf (Shared Housing (SRO)).
City Planning’s PLUTO file lists a residential FAR of 3.00 for this lot, which at 17,973 sf of land is 53,919 sf. The engine’s largest residential-only scheme without an affordability obligation (Shared Housing (SRO)) holds 35,946 sf, 33% less than that simple multiplication suggests. On this lot the building rules, not the FAR, set the limit; the full study shows which one binds.

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 18, 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.
