Except as herein provided, in any residential district where the owner of a lot, on or before November 1, 1973, or his/her successor in title thereto does not own sufficient land to enable him to conform to the minimum lot area and/or setback requirements of this chapter, such lot may be used as a building site for a single-family dwelling, provided that all requirements for the district in which said lot is located are maintained.

The height limitations of this chapter may be waived so as not to apply to water towers, transmission towers or church spires if approved by the Board of Adjustment.
