If you are building a new ADU that will be detached from the main residence or building(s), the ADU needs to be at least 4 feet from the side and rear property lines and maintain the front yard setback required in the zone of the property. (See Example Illustration).
A minimum 10-foot separation is needed between the new ADU and the main residence or other structures.
Setbacks do not apply when converting an existing accessory structure, like a garage, pool house, or detached recreation room into an ADU. Enlarging or modifying an existing structure for an ADU would require meeting the setbacks.
An ADU that is attached to the main residence must follow the same setbacks as the main residence.
