When an existing lot, regardless of its size, is to be split into two adjacent lots and ownership is to be transferred to adjacent lot owners or when part of an existing lot is transferred to an adjacent lot owner, no subdivision plat will be required unless a dwelling unit is to be placed on one of the parcels being transferred. Should a dwelling unit be placed on one of the transferred parcels either at the time of the lot split or at some future time, then the lot split will be treated as a subdivision. In any case, a copy of the deed or survey of the lot involved shall be submitted to the Planning Commission for its files. If a lot split results in the creation of a remainder tract, this tract must meet the criteria set forth in §
360-8D.
