Where, at the effective date of this ordinance or amendment thereto, lawful use of a structure, or of a structure and land in combination, exists that is made no longer permissible under the provisions of this subject to the following limitations:

  1. No existing structure devoted to a use not permitted by this chapter in the zoning district in which it is located shall be enlarged, extended, constructed, reconstructed, moved or structurally altered except in changing the use of the structure to a use permitted in the zoning district in which it is located.

  2. Any non-conforming use may be extended throughout any parts of a structure which were arranged or designed for such use, and which existed at the time of adoption or amendment of this ordinance, but no such use shall be extended to occupy any land outside such structure.

  3. If no structural alterations are made, any non-conforming use of a structure, or structure and premises, may be changed to another non-conforming use provided that the ZBA, either by general rule or by making findings in the specific case, shall find that the proposed use is equally appropriate or more appropriate in the district than the existing non-conforming use; in permitting such change, the ZBA may require appropriate conditions and safeguards in accord with the purpose and intent of this ordinance.

  4. Any structure, or structure and land in combination, in or on which a non-conforming use is superseded by a permitted use, shall thereafter conform to the regulations for the district in which such structure is located, and the non-conforming use may not thereafter be resumed.

  5. When a non-conforming use of a structure, or structure and premises in combination, is discontinued or ceases for six (6) consecutive months or for eighteen (18) months during any three-year period, the structure, or structure and premises in combination, shall not thereafter be used, except in conformance with the regulations of the zoning district in which it is located; structures occupied by seasonal uses shall be excepted from this provision. These provisions may be waived, as determined by the Village President, upon substantiation that there is intent to continue the nonconformity.

  6. Where non-conforming use status applies to a structure and premises in combination, removal or destruction of the structure shall eliminate the non-conforming status of the land.
