Will I need to add parking?

Parking is much less of a concern than it used to be. JADUs do not require a parking spot. Check County ADU Rules  and talk with your staff to see if ADUs require additional parking. No new parking is required if ADU is: 1) within ½ mile walking distance to transit (including a ferry); 2) within an architecturally or historically significant district; 3) on-street parking permits are required and not provided to the occupant of the ADU; 4) located within one block of car-share access, or 5) built as part of a new home. Check the County ADU Rules to see what parking may be required.
