A. 
Existing lots of record. A single-family structure may be constructed on any lot in any residential district if said lot is less than the minimum area required for building lots in the residential district in which it is located, provided that the following conditions exist or are met:
1) 
No structure shall be erected on any nonconforming lot if the owner of said lot owns any adjoining vacant land which would create a conforming lot if said vacant land were combined with the lot deficient in area.
2) 
No structure shall be constructed on a nonconforming lot unless it shall have a minimum side yard of three feet, or a minimum side yard of 10 feet where adjacent to any street.
3) 
No structure shall be constructed on a nonconforming lot unless it shall have front and rear yards conforming to the minimums required for the residential district in which said lot is located.
B. 
Lot width. The minimum lot width of any lot shall be measured along the minimum building setback line as required for the district in which it is located.
C. 
Required area or space cannot be reduced. The area or dimension of any lot, yard, parking area or other space shall not be reduced to less than the minimum required by this chapter, except as provided in this chapter; and, if already less than the minimum required by this chapter, said area or dimension may be continued but shall not be further reduced.
D. 
Corner lots. For the purposes of this chapter, corner lots shall be considered to have two front property lines, where abutting the street, and two side property lines.
E. 
Flag lots. Flag lots shall be prohibited.
At all street intersections no obstruction to vision (other than an existing building, post, column or tree) exceeding 30 inches in height above the established grade of the street at the property line shall be erected or maintained on any lot within the triangle formed by the street lot lines of such lot and a line drawn between the points along such street lot lines 30 feet distant from their point of intersection.
A. 
General application. No building or structure shall have a greater number of stories, nor have an aggregate height of a greater number of feet than is permitted in the district in which such building or structure is located, except as noted in Subsection B.
B. 
Height exceptions. The limitations affecting the height of structures shall not apply to the appurtenant appendages and structures, such as those listed below, provided that such appendages and structures comply with all the other provisions of this chapter or any other applicable local law.
1) 
Parapet walls not exceeding three feet in height;

Every part of a required yard must be open to the sky unobstructed except for accessory buildings in a rear or side yard, and except for the ordinary projection of open porches, balconies, steps, sills, belt courses, cornices and for ornamental features projecting not more than five feet.
B. 
Varied side yards. Where the side wall of a building is not parallel with the side lot line or is broken or otherwise irregular, the side yard may be varied. In such case, the average width of the side yard shall not be less than the otherwise required minimum width; provided, however, that such side yard shall not be narrower at any one point than 1/2 the otherwise required minimum width.
C. 
Transitional yard requirements.
1) 
Abutting on street line. Where a residence district abuts a nonresidence district on a street line, there shall be provided in the nonresidence district for a distance of 50 feet from the district boundary line a front yard at least equal in depth to that required in the residence district.
2) 
Abutting on side or rear yard. Where the side or rear yard in a residence district abuts a side or rear yard in a nonresidence district, there shall be provided along such abutting line or lines a side or rear yard at least equal in depth to that required in the residence district. In no case, however, shall the abutting side yard be less than 20 feet and the abutting rear yard be less than 20 feet.
