3. Location Of Entrances: Only one entrance may be located on the facade of the primary dwelling unit, attached primary dwelling unit, or manufactured home facing the street, unless the primary dwelling unit, attached primary dwelling unit, or manufactured home contained additional entrances before the accessory dwelling unit was created. An exception to this regulation would be entrances that do not have access from the ground such as entrances from balconies or decks.
4. Parking: Parking for the main residential structure must meet the requirements of chapter 5 of this title.
