165A.25   NONCONFORMING LOTS OF RECORD.
In any district, notwithstanding limitations imposed by other provision of this Zoning Code, a primary structure and customary accessory buildings may be erected on any single lot of record at the effective date of adoption or amendment of this Zoning Code. This provision 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 the yard dimensions and other requirements not involving area or width, or both, of the lot shall conform to the regulations for the district in which such lot is located. Variance of yard requirements shall be obtained only through action of the Board of Adjustment.
