Inland Accessory Dwelling Units

Standard ADU Application

There are two (2) different Accessory Dwelling Unit (ADU) or Junior Accessory Dwelling Unit (JADU) options for single-family dwellings and two (2) different ADU options for multi-family dwellings.  As you click on the type , further detail will be provided.  Only one option may be used on any given parcel.

Pre-Reviewed ADU Program Application

The County offers a Pre-Reviewed ADU Program where Residential Single-Family customers choose from County reviewed plans, allowing 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.
