Whenever a lawfully existing building or other structure otherwise conforms to the use regulations herein but is structurally nonconforming only in the particular manner hereinafter specified, a nonconforming building or structure shall be exempt from the requirements of Section 15.304 but shall not be exempt from the remaining requirements of this Article, including those pertaining to nonconforming uses:
A. In any district, when a given single family dwelling or an accessory structure thereto has met all of the zoning requirements of the district within which it was located at the time it was constructed, where the nonconformity is caused solely by a changed zoning district bulk regulation, provided no such building or lot shall be altered in any way so as to increase the number of dwelling units therein or thereon; and provided further, however, that a minimum of two (2) contiguous acres shall be necessary in the event a horse is stabled on any lot not meeting the minimum lot area requirements of this Chapter.
B. In any commercial district, where the existing building or structure is closer to the zoning line of an adjacent residential district than that specified in the regulations for the district in which it is located.
C. In any district, an existing building or structure which has been placed on the National Register of Historic Places and/or designated by the President and Board of Trustees of the Village as a Mettawa Landmark or Historic District and is nonconforming in any respect with the standards prescribed in this Chapter.
