At least three paved or asphalted off-street parking pads are required — at least one must be behind the front setback line, and no more than one stall may be in the side yard setback adjacent to a street. If the property is not connected to city sewer and the sewer main is within 300 feet, the owner must connect to city sewer before adding an ADU. The ADU must meet all applicable building codes. Building plans submitted to the city must show the location of required parking. Contact Orem Development Services at (801) 229-7058.
