Frequently Asked Questions

Can my Southern California property qualify for an ADU?

Many California properties may qualify for an ADU, but eligibility depends on state law, local zoning, site conditions, and the details of your property. We can help you review the next steps with your local jurisdiction.

Do I have to replace parking if I convert my garage?

In some cases, California law provides parking exemptions for ADUs, including certain properties near public transit. The rules depend on the property and project, so confirm requirements with your local jurisdiction.

What financing options are available for an ADU?

Homeowners may explore renovation, construction, or other financing options. Eligibility, payment schedules, and loan terms vary by lender, borrower, and project; discuss the details with a qualified lender.
