Except for an attached accessory dwelling unit that meets the Statewide Exemption Accessory Dwelling Unit Standards in Section 18.106.020, attached accessory dwelling units shall be subject to the mini- mum front, rear, and side yard requirements of the main structure as identified in Chapter 18.84, including re- quirements prescribed in Section 18.84.100. Only in instances when complying with the front yard setback for the main structure precludes an accessory dwelling unit shall the accessory dwelling unit be permitted to en- croach into the front yard setback but this encroachment shall be limited only to the extent necessary to accom- modate the accessory dwelling unit. No setbacks are required for a legally existing living area that is converted to an accessory dwelling unit or to a portion of an accessory dwelling unit. Height of the attached accessory dwelling unit is measured vertically from the average elevation of the natural grade or finished grade, whichever is lower, of the ground covered by the accessory dwelling unit to the highest point of the structure including parapet or to the coping of a flat roof, to the deck line of a mansard roof, or to the mean height between eaves and ridges for a hip, gable, or gambrel roof.

Accessory dwelling units that result from conversion of existing space may exceed these size limits. The gross floor area of the existing main dwelling unit is to be calculated based on the size of the unit prior to the ac- cessory dwelling unit/conversion. In no case shall this requirement necessitate an accessory dwelling unit to be less than: (1) a 150 square foot efficiency unit; (2) 850 square feet if the accessory dwelling unit is a studio or one-bedroom unit; or (3) 1,000 square feet if the accessory dwelling unit is two or more bedrooms.
