Avoid This Common Error in NYC: Split Zoning Lot Analysis

We see this misapplied all the time—and it throws off the entire analysis.
A split zoning lot spans two districts → R7A / R8 → seems straightforward.
Apply each district separately. Move on.
That’s where things go wrong.
Not because the math is complicated, but because the framework is wrong from the start.
The NYC Zoning Resolution does not treat this as two independent sites.
It’s one zoning lot and if you don’t analyze it that way, your FAR, massing, and conclusions can all drift.
We looked at a site in the Bronx where this exact issue comes into play.
In this video, we break down:
👉 the assumption most people make
👉 why it doesn’t hold up under the ZR
👉 and how to approach split-district lots correctly
This isn’t a niche edge case.
If you work in NYC, you will run into this.
Get it wrong, and the entire analysis is built on a bad foundation.
