27.22.090 REAR YARDS.

On a parcel upon which a building is constructed there shall be a rear yard setback of not less than fifteen feet (15'). For buildings more than three stories in height, the minimum rear yard shall be one-half (1/2) the height of the building to a maximum of twenty-five feet (25') unless a greater dimension is required as a condition of approval for special use permits. When a parcel zoned for multiple family use abuts an R1 or R2 zoned parcel, the rear yard setback measured from the property line shall be equal to the building height. All required rear yards shall be unobstructed from ground level to the sky, except as otherwise provided in this title.
