Yes, in most jurisdictions, including California, you can build both an Accessory Dwelling Unit (ADU) and a Junior Accessory Dwelling Unit (JADU) on the same property, meaning you can have one of each on a single lot with a single-family residence; however, always check local regulations to confirm specifics for your area.
Key points to remember:
- One per lot: Typically, you can only build one ADU and one JADU on a single property.
- Attached JADU: A JADU is usually required to be attached to the main house or an existing ADU.
- Size limitations: JADUs are smaller than ADUs, with specific square footage restrictions depending on local codes.
- Owner occupancy: Some jurisdictions may require owner occupancy of either the ADU or JADU.
