After the effective date of this Zoning chapter and except as hereinafter provided:
A. 
No land shall be used or occupied and no building or other structure shall hereafter be used, occupied, erected, moved or altered unless in conformity with the regulations herein specified. Existing nonconforming uses and nonconforming area and noncomplying bulk may continue, subject to the provisions of Article IX.
B. 
No part of a yard or other open space required about any building for the purpose of complying with the provisions of this chapter shall be included as a part of a yard or other open space similarly required for another building.
C. 
No land shall be used or occupied and no building shall be used, erected or altered to accommodate a greater number of families, or a greater residential density, than is specified or intended by this chapter.
D. 
No lot shall be formed from part of a lot already occupied by a building unless such building, all yards and open spaces connected therewith and the remaining lot comply with all requirements prescribed by this chapter for the district in which said lot is located. No building permit shall be issued for the erection or alteration of a building on any new lot thus created unless such building and lot comply with all provisions of this chapter or variances are obtained.
E. 
Any use not permitted by this chapter shall be deemed to be prohibited. The list of prohibited uses contained in § 250-17G of this chapter shall not be deemed to be an exhaustive list but has been included to illustrate by example the frequently proposed uses that are deemed undesirable and incompatible and are thus prohibited. Where an unlisted use is proposed to be placed in the Village, the applicant may seek a determination from the Zoning Board of Appeals as to whether the proposed use is substantially the same as a permitted, special use or prohibited use. In such cases the Zoning Board of Appeals shall examine the characteristics of the proposed use in relation to uses specifically permitted or prohibited. It shall be the responsibility of the applicant to furnish adequate information to permit the Zoning Board of Appeals to make its determination.
F. 
Nothing contained in this chapter shall require any change in the previously approved plans, construction or use of an existing building that complied with local laws in force prior to this Zoning chapter and where a building permit or certificate of occupancy had been duly issued before the effective date of this Zoning chapter.
