Potential.NYC

At a glance

Potential.NYC is a 3D map for exploring how New York’s floor-area rules compare with existing buildings. It is worth a look for understanding development-capacity patterns and discussing hypothetical zoning changes. Its blue envelopes are a simplified model of unused capacity, not a determination that a particular project can legally be built.

Good fit

Urbanists, residents and planning researchers who want to see a policy concept spatially. Floor area ratio, or FAR, relates building floor area to lot size. The map combines a lot’s area and FAR with an estimate of existing net floor area, making it easier to compare a modelled allowance with what is already present.

Consider something else when

You need a parcel feasibility study, transferable-air-rights determination or permit decision. The tool explicitly ignores height limits, setbacks and existing air-rights agreements. Its model divides gross building area by 1.2 to estimate net area; that is a modelling assumption, not a verified zoning-floor-area calculation for every building.

Start here

Open Methodology before interpreting the map. Select a public lot to see its zoning, lot area, gross building area and displayed FAR. The FAR control supports hypothetical changes: one tested increase changed the adjustment from 0 to +0.5, then was restored. Keep those scenarios separate from the parcel’s existing zoning information.

Cost and requirements

The public browser map describes itself as free. The tested parcel inspection and FAR control required no account, payment or location permission. Methodology identifies PLUTO 2025V4 for lot and building areas, NYC’s 3D model for footprints and heights, and CityTracker.ai calculations for FAR. The public map is distinct from the separately advertised commercial platform.

Limits to know

The trial inspected one Manhattan parcel and changed a scenario control; it did not independently verify the parcel’s records, quantify a changed envelope or establish buildability. The visualization assumes new construction stays on the existing footprint. Its declared data vintage and omitted restrictions make it an exploratory starting point; check current official records and project-specific constraints before acting on a site.

Still unclear

• How current are the FAR calculations and underlying parcel inputs for the specific site you want to study?
