Do You Know the Fundamentals of Zoning Rules? Here…


Embarking on a ground-up development project may seem like a monumental task, but the opportunity to build something entirely new makes it one of the most exhilarating ventures in real estate. But, at the heart of any successful development analysis lies a thorough understanding of zoning.

This guide will dissect the key facets, from general zoning classifications to intricate parameters such as height restrictions, setbacks, unit density, and the critical interplay of community incentives and neighborhood ordinances.

General Zoning: Decoding Designations

Zoning designations are slightly different in each city, but they share some common ground. In the code, like R3, the R means residential use—usually no offices or retail. The number 3 signals more density and height are allowed compared to, say, R2. Similarly, C means it’s for commercial, and M is for manufacturing. 

These simple designations help us understand the basic rules of land use in any city.

Zoning Parameters

Here’s a look at some specific zoning parameters. 

Height restrictions and FAR

In most cities, there are designated areas for single-family homes (SFH), typically zoned as R1 or R2, where only single- or two-story structures are permitted. Multifamily buildings and taller structures are usually allowed in areas zoned as R3 or higher. For instance, in densely populated cities like New York, residential zones can go up to R10.

Some zoning allows for unlimited stories, but in these cases, your building’s height is constrained by the floor area ratio (FAR). FAR sets the limit on the total gross building area permitted. For example, if the zoning permits a 10,000-square-foot (sf) building based on the FAR and each floor covers about 2,000 sf, you’re restricted to constructing around five stories without surpassing the FAR limit.

Setbacks

Zoning regulations use building setbacks—side, front, and rear distances—to shape urban structures. By…
