1139.02  HEIGHT AND BULK REQUIREMENTS.
   In a Commercial B District, the following limitations and requirements shall apply:
   (a)    Height.  No building shall be built to a height exceeding one and one-half times the width of the street upon which the building abuts. Buildings may exceed the above height limit, providing the portion of the building greater than one and one-half times the width of the street is set back from every street and lot line, one foot for each three feet of height in excess of one and one-half times the width of the street. The height limitations of a wider street shall govern for a distance of one hundred and twenty feet along a narrower intersecting street, measured at right angles to such wider street.
   (b)    Side Yards.  There shall be a side yard on each side of every building or portion of a building used as a dwelling. The minimum width of any such side yard shall be five feet which shall be increased three feet for each additional story above two stories.
   (c)    Courts.  An outer court may be substituted for a side yard providing every room in which people live or sleep can be adequately lighted and ventilated from such court. Such outer court shall be in width not less than eight percent of the width of the lot, which court width shall also be at least three inches for every foot of height of the highest wall abutting such court. Such court shall be not less in length than twice its width. Wherever any room in which people live or sleep cannot be adequately lighted and ventilated from a street, rear yard, side yard or outer court, an inner court must be provided which inner court shall be not less than eight feet wide nor less than three inches in width for every foot of height of the highest wall abutting such court. Such inner court shall be not less in length than twice its width.
   (d)    Rear Yard.  Dwellings shall have a rear yard, the minimum depth of which shall be sixteen feet, increasing four feet for each additional story above the first story.
   (e)    Set-back.  No building shall be erected, reconstructed or altered so as to project any portion of the building above the curb grade, beyond the lines as designated on the Map, "Building Line Map for Commercial B, Industrial A and Industrial B Districts." Such Map and all notations or references shown thereon shall be as much a part of this Zoning Ordinance as if the notations and information shown thereon was fully written and described herein.
