Accessory buildings on corner lots, shall conform to the setback regulations of the principal structure. Accessory buildings with the intent of being a garage shall also have a driveway eighteen (18) feet in length. If an accessory building is attached to the principal building by a breezeway or similar structure, such as a common wall, then the accessory building shall be considered part of the principal building and can be located in the side yard if it complies with all setback requirements. An accessory building, which is not a part of the main building, shall not occupy more than thirty percent (30%) of the rear yard and shall not exceed eighteen (18) feet in height measured from the finished floor to the highest peak.
[CC 1974 §43.055]
For corner lots platted or of record after the effective date of this Chapter, the front yard regulations shall apply to each street side of the corner lot.

On corner lots platted or of record prior to the official date of the enactment of this Chapter, the side yard regulations shall apply to the longer street side of the lot except in the case of reverse frontage where the corner lot faces an intersecting street. In this case there shall be a side yard on the longer street side of the corner lot of not less than fifty percent (50%) of the front yard required on the lots to the rear of such corner lots and no accessory building on said corner lot shall project beyond the setback line of the lots in the rear; provided further, that this regulation shall not be so interpreted as to reduce the buildable width of a corner lot facing an intersecting street and of record or as shown by existing contract of purchase prior to the official date of the enactment of this Chapter to less than twenty-eight (28) feet nor to prohibit the erection of an accessory building.
[CC 1974 §43.060]
No yard shall be reduced in area so as to make any yard or any other open space less than the minimum required by this Chapter.

In cases where the height of a proposed structure on such lot in the less restricted district is greater than the maximum height permitted in the adjoining more restricted district, the minimum depth or width of the side yard, rear yard or court for such structure shall be determined by increasing the minimum width or depth for the highest structure permitted in such more restricted district by one (1) foot for each two (2) feet by which the proposed structure exceeds the maximum height permitted in said more restricted district.
[CC 1974 §43.070]
A. 
Whenever the plat of a land subdivision approved by the Planning Commission and on record in the office of the County Recorder shows a setback building line along the frontage for the purpose of creating a front yard or side street yard line, the building line thus shown shall apply along such frontage in place of any other yard line required in this Chapter unless specific yard requirements in this Chapter require a greater setback.
1. 
Zoning district dividing property. Where one (1) parcel of property is divided into two (2) or more portions by reason of different zoning district classifications, each of these portions shall be used independently of the others in respective zoning classification and for the purpose of applying the regulations of this Chapter, each portion shall be considered as if in separate and different ownership.

Transition yard requirements. When this district abuts in the rear or on the sides of any "R" district, the rear yard or side yard requirements, whichever the case may be, of any building or structure on the premises of this district shall be set back from its side or rear lot line, whichever the case may be, a distance of two (2) linear feet for each one (1) foot of building or structure height, this will then determine the minimum yard requirements, except as otherwise provided therein.
[CC 1974 §43.210; Ord. No. 3324 §1, 2-17-1987]
A.

In any "R" district, where the average depth of at least two (2) existing front yards on lots within one hundred (100) feet of the lot in question and within the same block front is less or greater than the least front yard depth prescribed elsewhere in this Chapter, the required depth of the front yard on such lot shall be modified. In such cases, this shall not be less than the average depth of said existing front yards on the two (2) lots immediately adjoining or, in the case of a corner lot, the depth of the front yard on the lot immediately adjoining, provided however, that the depth of a front yard on any lot shall be at least ten (10) feet and need not exceed fifty (50) feet and provided that in no event shall the depth of a front yard of a corner lot be less than twenty-five (25) feet.

3. 
Rear and side yards — how computed. In computing the depth of a rear yard or the width of a side yard where the rear or side yard abuts an alley, one-half (½) of the width of the alley may be included as a portion of the required rear or side yard, as the case may be. However, in no event shall any building or structure be erected closer than five (5) feet from any lot line.
4. 
Side yard increased. Each side yard, where required, shall be increased in width by two (2) inches for each foot by which the length of the side wall of the building, adjacent to the side yard, exceeds forty (40) feet.
