Zoning Setback Requirements
The minimum distances a building must keep from property lines.
What are setback requirements?
Setbacks are the minimum distances a building must be kept from the edges of its lot — the front, sides, and rear property lines. Zoning uses them to control spacing, light, air, and neighborhood character, and they directly limit where and how large you can build.
Types of setbacks
Most districts set a front-yard setback from the street, side-yard setbacks from the neighbors, and a rear-yard setback. Together with height limits and floor area ratio, setbacks define the buildable envelope — the three-dimensional space you are actually allowed to build within.
When a setback blocks your plan
If a design cannot meet a required setback, the owner typically needs a dimensional variance. Because setback relief is judged more flexibly than a use variance, a well-presented request often succeeds — but it still requires going through the variance process.
