Where the owner of a plot of land consisting of one or more adjacent lots at the time of the enactment of the ordinance from which this chapter is derived did not at that time own sufficient contiguous land to enable him to conform to the minimum lot size requirements of this article, such plot of land may nevertheless be used as a building site. The yard and other space requirements of the district in which the piece of land is located may be reduced by the smallest amount that will permit a house of minimum acceptable size to be built upon the lot.

(Comp. Ords. 1970, app. II, § 9.1)

The front yard setback requirements of this article for dwellings shall not apply on any lot where the average setback of existing buildings located wholly or in part within 100 feet on each side of such lot within the same block and zoning district and fronting on the same side of the street is less than the minimum required setback. In such cases, the setback on such lot may be less than the required setback but not less than the average of the aforementioned existing buildings.

(Comp. Ords. 1970, app. II, § 9.2)

The height limitations of this chapter shall not apply to church spires, belfries, cupolas and domes not intended for human occupancy; nor to monuments, water towers, transmission towers, chimneys, smokestacks, derricks, conveyors, flagpoles, radio or television towers or aerials.
