FAQ

Torrance ADU questions.

Ask about your lot

How are ADUs approved in Torrance?

Torrance reviews ADUs ministerially as part of the building permit. That means no public hearing for a code-compliant ADU.

Can I build an ADU in the Torrance coastal zone?

Often, yes, but coastal-zone lots need California Coastal Commission review on top of the city permit. We flag that in your feasibility report.

Did the Torrance ADU rules change?

Yes. Torrance amended its ADU ordinance in October 2025. We apply the current rules to your lot.
