About Us

The New York City skyline you see today is also a timeline, across both trends in architectural creativity and ever-changing rules they must follow for their vision to be realized.

The New York City Zoning Laws were originally conceived in 1916 in response to innovations that made larger and larger structure possible, resulting in a critical need to set aside space for light, air, public use… In the intervening century zoning laws were expanded with increasing complexity, to include preservation of historic structures and contexts, economic incentives, and other needs of the City’s ever growing and changing communities.

But the labor intensive process for builders to sort through all of this paperwork remained relatively unchanged...until now.

Enter Zoner! In just moments, with a few clicks and keystrokes, architects, developers, owners, realtors and community boards are live with an interactive, visual model of what can be built in the designated space, Zoner covers all applicable zoning parameters, including: maximum building bulk and height; the allowable use of the site; special districts and landmark rules; required setbacks and much more.

For example, here is how the City zoning website describes requirements for an iconic type of “brownstone” district :

“The street wall of a new building, on any lot up to 50 feet wide, must be as deep as one adjacent wall and no deeper than the other. On lots wider than 50 feet, the street wall of a new build­ing may be no closer to the street line than the street wall of an adjacent building. A street wall need not be located farther from the street line than 15 feet.”

Quite a distance from there to what it all means for your project. Zoner generates specific measurements -- and visuals -- in seconds!
