In any district in which single-family dwellings are permitted, a single-family dwelling and customary accessory building may be erected on any single lot of record on the effective date of this chapter (Ordinance 76-31, passed June 21, 1976), or an amendment thereof, notwithstanding limitations imposed by other provisions of this chapter. Such lot must be in separate ownership and not of continuous frontage with other lots in the same ownership. This section shall apply even though such lot fails to meet the requirements for area or width, or both, that are generally applicable in the district, provided that yard dimensions and requirements other than those applying to area or width, or both, of the lot shall conform to the regulations for the district in which such lot is located. Variances of requirements of this Zoning Code, other than lot area or width, shall be obtained only through action of the Board of Zoning Appeals as provided in Chapter 1264. (Ord. 76-31. Passed 6-21-76.)
