Development & air rights

Insufficient data. NYC PLUTO does not publish a usable lot area or building area for this parcel, so no development-rights estimate can be made. We would rather show nothing than a number we cannot stand behind.

Estimated from NYC PLUTO zoning data. This is not a zoning analysis — confirm with a zoning attorney or architect before relying on it. As-of-right only: excludes bonuses, air-rights transfers and variances.

Compiled from NYC Open Data: PLUTO (lot and building attributes), ACRIS (deeds and mortgages), DOB NOW (permits) and HPD (violations). Public record, presented as recorded; Crezly does not warrant it. BBL 3027670001 · data refreshed 2026-10-31
