ADUs must be placed at a minimum of 60 feet away from the front property line. There are no rear yard setbacks or side property line limitations. However, the two-story setbacks of this type should be 4 feet. If the design includes additional features, like an open stair landing or balcony, and they are placed towards a rear or side lot line nearest to ADU, these features must be no bigger than 3 feet in height.
