Zoning Glossary

Side Setback

A side setback is the minimum required distance between a side property line and the nearest wall or point of a structure on the lot. Side setbacks provide a buffer between adjacent buildings on neighboring lots, supporting light and air circulation and creating fire separation between structures. They are typically the smallest of a lot's three primary setback types. The applicable distance is found in the zone's development standards and may differ for interior side yards versus the street-facing side yard on a corner lot.

Zoning

In Practice

The side setback determines how close your structure can be positioned to the left and right boundary lines of your lot. On corner lots, the side yard that faces a second public street may be subject to a larger setback requirement comparable to a front setback. Side setback distances vary by zone and sometimes by the type of structure being built — verify the applicable standard for both primary and accessory structures in your zone before positioning any construction.
