Where unnecessary hardships and practical difficulties, resulting from peculiarities of a specific property, render it difficult or inequitable to carry out the provisions of this title, the hearings examiner shall have power to grant a variance in harmony with the general purpose and intent of this title. Such variance may vary the literal enforcement of any standard, requirement, or regulation of this title relating to the density, but not the use, provisions of the district wherein is located the property which is the subject of the application for variance, so that the intent of the title will be observed, public interest protected, public safety secured and substantial justice done. To this end, a variance in the provisions and requirements of the title shall only be authorized if the hearings examiner finds that all the following facts and conditions exist in each case of an application for a variance:
1.
That there are exceptional or extraordinary circumstances or conditions applying to the subject property that do not apply generally to other properties in the same vicinity or zoning district, and that the plight of the applicant is unique and not the result of his own action;
2.
That the land or structure in question cannot be reasonably used and cannot yield a reasonable return if used only in accordance with the density requirements of the title for the district in which it is located, and that such variance is necessary for the preservation and enjoyment of a substantial property right of the applicant possessed by the owners of other property in the same vicinity or district;
3.
That the authorization of such variance will not be materially detrimental to the public welfare, not injurious to nearby property, nor essentially different from the provisions of the district in which it is located;
4.
That the granting of such variance will not adversely affect the comprehensive plan or studies thereof.
