It is the purpose of this Article IX to provide for the regulation of legally nonconforming uses, structures, and lots, and to specify those circumstances and conditions under which such nonconformities shall be permitted to continue. In order to protect the orderly development and taxable value of other properties in the Village, it is necessary and consistent with the regulations prescribed by this Zoning Ordinance that nonconformities not be permitted to continue without restriction.

The provisions of this Article IX are designed to curtail substantial investment in nonconformities and to bring about their eventual improvement or elimination in order to preserve the integrity of this Zoning Ordinance and enhance the character of the Village. Any nonconforming use, structure, or lot which lawfully existed as of the effective date of this Zoning Ordinance and which remains nonconforming, and any use, structure, or lot which has become nonconforming as a result of the adoption of this Zoning Ordinance, or any subsequent reclassification of zoning districts or other amendment to this Zoning Ordinance, may be continued or maintained only in accordance with the terms of this article
