A.
In any residential zone, only a one-family dwelling may be erected on a nonconforming lot of official record at the effective date of this chapter, irrespective of its area or width; provided, however, that no adjacent or adjoining vacant land exists or existed at the time of the effective date of this chapter which would create a conforming lot if all or part of said vacant land were combined with the subject lot. No lot or lots in single ownership hereafter shall be reduced so as to create one or more nonconforming lots.
B.
The area or dimension of any zone lot, yard, parking area or other space shall not be reduced to less than the minimum required by this chapter, and if already existing as less than the minimum required by this chapter, said area or dimension may be continued and shall not be further reduced.
C.
Any nonconforming lot existing on or before October 22, 1968, for use as a single-family dwelling, may have a building permit issued without an appeal for a variance, provided the new structure or addition does not violate the building coverage requirements, any height or setback requirements and the parking requirements and the nonconforming lot abuts lots on either side that are developed and the nonconforming lot is the largest possible assemblage of contiguous land under the preceding subsection. The side and rear yards may be reduced by the same percentage that the area of the undersized lot bears to the zone district requirements, except that no yard shall be less than 1/2 that required by this chapter or five feet, whichever is greater, as set forth in this chapter.
D.
Two-family dwellings shall be a permitted use in the R-2 Residential Zone subject to the submission of a plot plan to the Planning Board as defined under § 96-2.2 herein. All two-family buildings that are to be constructed as a new building, an expansion of a one-family residence to a two-family dwelling; or a modification in an existing two-family dwelling, whether or not the application requires one or more "c" variances shall be required to submit a plot plan to the Planning Board.
E.
Whenever land has been dedicated to the Village in order to meet the minimum street width requirements or to implement the Official Map or Master Plan, the Building Inspector shall not withhold a building and/or occupancy permit when the lot depth and/or area was rendered substandard due to such dedication and where the owner has no adjacent lands to meet the minimum requirements.
F.
For any zone lot which is located in more than one zone district, which districts differ in character by permitting residential, commercial, office or industrial uses, all yard, bulk and other requirements shall be measured form the zone boundary line and not the true lot line.
