Zoning Glossary

Rear Setback

A rear setback is the minimum required distance between the rear property line and the nearest point of a structure on the lot. Rear setbacks protect the privacy and usability of back-of-lot space for both the subject property and neighboring properties, and they define the zone of the rear yard where detached accessory structures are commonly placed. The applicable distance is specified in the zone's development standards. Separate setback standards for accessory structures — such as detached ADUs or garages — may differ from the rear setback that applies to the primary dwelling.

Zoning

In Practice

The rear setback determines the buildable limit of your lot from the back property line. The space between the primary dwelling and the rear property line is where detached garages, sheds, and accessory dwelling units are commonly constructed, though those structures carry their own setback rules that may be more permissive than the rear setback governing the primary structure. Confirm both the primary dwelling and accessory structure rear setback requirements for your zone before planning any rear-yard development.
