A single-family dwelling may be constructed on any lot in any residential district if said lot is less than the minimum area and/or width required for building lots in the district in which it is located, provided that the following conditions exist or are met:
A. 
Availability of adjacent vacant land. 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.
B. 
Side yards. No structure shall be constructed unless it has a minimum side yard of three feet.
C. 
Front and rear yards. No structure shall be constructed unless it has front and rear yards conforming to the minimums required for the residential district in which said lot is located.
Where a single lot under individual ownership extends from one street to another parallel or nearly parallel street or alley, the widest street shall be deemed the street upon which the property fronts, and no principal structure and no dwelling shall be erected on the rear of such lot, except where such lot may be subdivided to create not less than two conforming lots. Where a single lot extends between two streets of equal width, either street may be deemed as that upon which the property fronts, but only one street shall be so deemed.
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 elsewhere in this chapter.
B. 
Permitted exceptions. The stated maximum height shall not apply to any of the following structures when lawfully existing, permitted, or permissible in the district, provided that the structure does not exceed maximum height restrictions by more than 25% and is not used as a place of habitation.
(1) 
Chimneys, cooling towers, fire towers, steeples, tanks, water towers, ornamental towers, or spires.
(2) 
Elevators, bulkheads, or necessary mechanical appurtenances, provided that such structures do not occupy more than 15% of the roof area.

Antenna location.
(a) 
In any industrial district, such antenna may be located on the lot or building thereon.
(b) 
In any other district, subject to the provisions contained herein, such antenna shall be located only in the rear yard of any lot. If a usable satellite signal cannot be obtained from such rear yard, the antenna may be located in the side yard or on the structure on the property, subject to site plan approval in accordance with this chapter. In such instances, the applicant must provide written evidence from a satellite-receiving station installer, showing that a usable satellite signal is not obtainable from any other rear lot location on the property.
(3) 
Restrictions.
(a) 
In a residential or mixed use district, such antenna shall not exceed existing height regulations by 25% or more than 15 feet above the existing peak of the structure, including any platform or structure on which said antenna is mounted or affixed. Such antenna may not exceed 12 feet in diameter.

At all street intersections, no obstruction to vision (other than an existing building, post, column, or tree) exceeding three feet in height above the established grade of the street at curb line shall be erected or maintained on any lot within the clear sight triangle.
B. 
The clear sight triangle shall be defined by the triangle formed by the curb lines of the intersecting streets measured 15 feet outward from the point of intersection of said curb lines along such curb lines. This shall only apply to intersections where a building does not occupy this space. See Figure 25-1.
