Pre-reviewed ADUs in Coastal Zone

The County offers a Pre-Reviewed ADU Program where Residential Single-Family customers choose from County reviewed architectural and structural plans, with a selection of design styles. This program allows for a more cost-effective and streamlined process.

Though these plans are free, customers will still need to hire an engineer or architect for additional site-specific items, and review the Pre-Reviewed ADU Checklist.

These Pre-Reviewed ADU plans cannot be modified.

Pre-reviewed ADU customers must submit the below inquiry to allow County Planning Staff to conduct an initial review of the parcel. Planning staff will respond with an email indicating if there are any unforeseen restrictions to the parcel.
