How can I apply for an ADU?

Follow the ADU Step-by-Step Guide and submit a “DRP – Base Application Permits and Reviews” through EPIC LA. Don’t forget to complete and upload the Land Use Checklist to your online application.

If you have any questions, please email .(JavaScript must be enabled to view this email address), or call (213) 974-6411. You may also talk to a planner at your local field offices or by scheduling a virtual appointment.

When will I be able to use a Pre-Approved ADU Standard Plan?

Beginning in January 2023, a catalog of Pre-Approved ADU Standard Plans will be available for you to browse on the Standard Plans page. After choosing your preferred model, you’ll contact the architect directly to purchase, finalize, and submit the plan for permits. Standard Plans will speed up County review and approval processes, give you a head start to building an ADU (especially if you don’t know where to start), and ensure that you work with qualified, experienced professionals.
