What is an ADU? |
|
| |
• An Accessory Dwelling Unit (ADU) is a residential unit that can be added to a lot with an existing single-family home or multi-family development.
• ADUs can be located in a few different places, either detached (such as a separate building in a backyard), attached to a part of the primary residence as an addition, or be converted from an existing garage or other part of the primary residence.
• ADUs are independent rental units that have their own kitchens, bathrooms, and entrances.
• ADUs have many names:
- accessory apartments
- secondary suites
- in-law unit
- granny flat
- studio
- carriage house
- etc.

What is a JADU? |

• A Junior Accessory Dwelling Unit (JADU) is a part of an existing single-family home that is re-purposed as a private dwelling by incorporating a small kitchen and separate entrance.
• The difference between a JADU and ADU is that JADUs must be located within the existing primary residence and be no greater than 500 square feet in size.
• JADUs require owner occupancy either in the primary residence or accessory unit.
