Parking
In many cases, Campbell requires additional parking for ADUs. However, if your property is near public transportation, you may not need to add more parking spaces.

Design
Campbell prefers ADUs that look like they belong with the main house and neighborhood. For example, if your main house has a traditional style, the ADU should match it.
