What permits are required for ADUs and JADUs?

Application requirements vary by where you live, but applications typically include:

• Site plan (depicting existing and proposed structures)
• Building/architectural plans (floor plans, elevation plans, and details)
• Structural plans (foundation plan, framing plans, and associated details)
• Other items (Title 24 energy calculations, deed restriction, address assignment form, or other materials required by your location)
• Deed Restriction filed with the County
• Supplementary materials

Some local Planning Departments have an ADU permit application or submittal requirements checklist that outlines all the required documentation and materials that must be submitted. Contact local staff (Link) to learn about your specific application process and requirements.
