(a) A lot or parcel of land may be divided into 2 or more zoning lots, provided, all lots resulting from the division shall conform to all lot area and width regulations of the district in which it is located. A lot of record (land designated as a separate parcel on a plat, map, or deed in the records of Erie County, Ohio), whether vacant or occupied by a building, which was owned separately from adjoining lots on the effective date of the Zoning Code, and which has an area or width equal to or less than required by these regulations, shall not be further reduced in any manner, except by its entire conveyance to an adjacent owner. The required lot area which is provided for a dwelling or other use shall not be considered as providing the required lot area for another dwelling or use.
(b) If 2 or more lots, or combinations of a lot and a portion of a lot or lots, in single ownership, are of record at the time of passage or amendment of Chapter 1129 and this chapter, and do not meet the requirements for lot width and area as established by Chapter 1129 and this chapter, except when considered as a unit, the land involved shall be considered to be an undivided parcel or unit for the purposes of Chapter 1129 and this chapter, and no portion of the parcel shall be used or transferred which does not meet lot width and area requirements established by Chapter 1129 and this chapter, nor shall any division of the parcel be made which leaves remaining any lot or parcel of land with width or area below the requirements stated in Chapter 1129 and this chapter. Provided, however, that a portion of the parcel may be transferred to the owner of property abutting the parcel for the purpose of enlarging the property of the abutting owner. In such event, the portion of the parcel being transferred to the abutting property need not meet the lot width and area requirements established by Chapter 1129 and this chapter, but the portion of the parcel being retained must meet the minimum lot width and area requirements established by Chapter 1129 and this chapter.
