A. Residential districts – In any residential district in which single-family dwellings are permitted, a single-family dwelling and customary accessory buildings may be erected on any single lot of record, notwithstanding limitations imposed by other provisions of this title. Such lot must be in separate ownership and not of continuous frontage with other lots in the same ownership. This provision shall apply even though such lot fails to meet the requirements for area or width that are generally applicable in the district, provided that yard dimensions and requirements (other than those applying to area or width) shall conform to the regulations for the district in which such lot is located.

In all residential zoning districts, if two or more lots or combinations of lots and portions of lots with continuous frontage are of record prior to May 23, 1960, and if all or part of the lots do not meet the minimum requirements established for lot width and area, the land involved shall be considered to be an undivided parcel for the purposes of this title, and no portion of the parcel shall be used or sold in a manner which diminishes compliance with the lot width and area requirements established by this title, nor shall any division of any parcel be made which creates a lot with width or area below the requirements stated in this title.

B. Other districts – In any other district, permitted buildings and structures may be constructed on a nonconforming lot of record, provided lot coverage, yard, landscaping and off-street parking requirements are met. Such lot must be in separate ownership and not of continuous frontage with other lots in the same ownership. If all or part of the lots do not meet the minimum requirements established for lot width and area, the land involved shall be considered to be an undivided parcel for the purposes of this title, and no portion of the parcel shall be used or sold in a manner which diminishes compliance with the lot width and area requirements established by this title, nor shall any division of any parcel be made which creates a lot with width or area below the requirements stated in this title.
