Torrance Permits & Zoning
Permits & Zoning in
Torrance
In most parts of Torrance, homeowners can build a detached ADU, attached ADU, or convert an existing garage. Many properties qualify for two-story ADUs due to wider lots and favorable setbacks. Garage conversions are especially popular in Torrance because many homes have detached garages with good driveway access. During your free ADU review, we confirm zoning, setbacks, and construction options based on your exact property location.

Frequently Asked Questions
Can I convert my garage into an ADU in Torrance?
Yes, most detached and attached garages in Torrance qualify for conversion as long as structural safety and fire separation can be confirmed. We review your garage during your ADU property analysis and tell you what's needed to make it legal.
How big can an ADU be in Torrance?
Most ADUs in Torrance are between 400–1,200 sq. ft. Since many Torrance lots are wider than average, two-story ADUs and larger detached ADUs are often possible.
Do I need to add parking for my ADU in Torrance?
In most cases, no additional parking is required, especially for garage conversions or properties located within half a mile of public transit (which covers much of Torrance).
Do I need an architect or engineer for an ADU in Torrance?
Yes. The City of Torrance requires full architectural plans, structural engineering, and Title 24 compliance. We handle all drawings, engineering calculations, permit submission, and city corrections.
How long does it take to get ADU permits approved in Torrance?
Most ADU permits in Torrance take 8–14 weeks, depending on zoning and project scope. California state law requires cities to respond within 60 days, but revisions may extend the process.
Does Direct ADU help with ADU design and engineering, or just construction?
We handle everything - including architectural plans, structural engineering, Title 24 compliance, interior layout, permit submittals, city corrections, and full construction. You won’t need to hire separate designers or engineers.
