(2) 
In the C-1 and C-2 districts there shall be a front yard, sidewalk or driveway having a depth of not less than 15 feet measured from the back of the curb.

In the I district, no front yard is required unless the building is erected or structurally altered for dwelling purposes, in which event, a front yard of not less than 15 feet from the back of the curb shall be required.
(4) 
Where the frontage on one side of the street between two intersecting streets is zoned for two classes of districts, the setback on the most restricted district shall apply to the entire block.
(5) 
(A)

(B) 
This regulation shall not be interpreted to require a front yard of more than 50 feet.
(6) 
On any lot on which a front yard is required by this article, no wall, carport, fence, or other structure shall be erected and no hedge, tree, shrub, or other growth of any kind shall be maintained in the location within the required front yard so as to obstruct the view.

These points shall then be connected with imaginary lines, thereby forming a triangle. If there are no curbs existing, the triangular area shall be formed by extending the pavement edges to the imaginary point of intersection of the streets and then proceeding in the same manner described above. If there is no pavement, the triangle area shall be formed by visualizing a pavement 20 feet in width, utilizing the imaginary point of intersection, and proceeding as above.
(C) 
No vehicle shall be parked and no fence, wall, screen, billboard, sign, structure, other view obstruction, foliage of hedges, trees, bushes or shrubs shall be erected, planted or maintained within the “intersection visibility triangle” so as to obstruct with sign [sight] lines at elevations between three feet and eight feet above the average street grade. Obstructions of this nature are declared to be a public traffic nuisance.
(D) 
Any fence, wall, screen, hedge, tree, bush, shrub, billboard, sign or structure erected, planted or maintained in violation of these subsections shall be removed within ten days upon written notice from the city to the owners of the affected or adjacent property.

In the C districts, if the property is not used for dwelling purposes no side yards are required unless a lot abuts upon the side of a lot zoned for dwelling purposes in which case, there shall be a side yard of not less than five feet on the side abutting the dwelling lot. In other cases a side yard, if provided for a business or industrial building, shall be not less than four feet.

In the R-2 district, for the purpose of side yard regulations, two or more detached one- or two-family dwellings shall be considered as one building when occupying one lot. There shall be a minimum of ten feet between the sides of the buildings on the same lot.
(4) 
In the case of group houses or court apartments, when buildings bear upon the side yard, the width of the side yard shall be increased by one foot for each building or apartment abutting thereon. If any stairways open onto or are served by the side yard the minimum width of the side yard shall be ten feet.
(5) 
The width of a place or court shall not be less than 40 feet measured between buildings or from buildings to the opposite property line, provided that open porches may project into the required place or court not more than 20% of the width of the place or court.
(6) 
All other requirements including front, side and rear yards shall be complied with in accordance with the districts in which the group houses or court apartments are located.

The side and front yard requirements for dwellings shall be waived where living quarters are erected above stores or shops.
(9) 
On corner lots the side yard regulations shall be the same as for interior except in the case of side street or reversed frontage (where the corner lot faces an intersecting street) in which case there shall be a side yard on the street side equal to the front yard on the lots in the rear. No accessory building on the corner lot shall project beyond the front yard line on the lots in the rear. This regulation shall not be so interpreted as to reduce the buildable width of a corner lot facing an intersecting street, and of record at the time of passage of this article, to less than 28 feet nor to prohibit the erection of an accessory building where the regulation cannot be reasonably complied with.

No nonconforming use constituting a public nuisance or a hazard to adjacent property may be continued.
(b) 
If no structural alterations are made, a nonconforming use of a building may be changed to another nonconforming use of the same or more restricted classification. The foregoing provisions shall also apply to nonconforming uses in districts as may be hereafter changed. Whenever a nonconforming use of a building has been changed to a more restricted use or to a conforming use, the use shall not thereafter be changed to a less restricted use. The regulations shall never be construed as allowing an addition to a nonconforming building except for matters of public health and safety.
