Detached ADU
A detached ADU is not connected to your primary house. The dwelling needs to be within your property setbacks and allowable building size (both height and square footage).
Junior ADU
Junior Accessory Dwelling Units (JADUs) are named this way because they are small (up to 500 square feet).
In California, the recent state bills
