NYC Development Potential
An interactive map scores New York City tax lots by the gap between their allowed zoning capacity and what has actually been built.
Field notes
The application uses a built-out-to-underbuilt scale to turn zoning capacity into a parcel-level screening layer, with search by address or BBL and filters for ownership, landmarks, permits, and infrastructure-related exclusions. Its coverage claim is unusually broad: every NYC MapPLUTO tax lot. The site also presents a pro forma workflow, but explicitly labels costs, rents, financing, cap rates, and tax assumptions as generic placeholders rather than acquisition-grade analysis.
