A.
If any mandatory provisions of this chapter are shown by the applicant, to the satisfaction of the Board of Commissioners, to be unreasonable and to cause undue hardship as they apply to his proposed subdivision or land development, the Board of Commissioners may grant a variance to such applicant from such mandatory provisions, so that substantial justice may be done and the public interest secured; provided that such variance will not have the effect of nullifying the intent and purpose of this chapter.
B.
It is not sufficient proof of hardship to show that greater profit would result if the variance were granted. Furthermore; hardship complained of cannot be self-created; it cannot be claimed by one who purchases with or without knowledge of restrictions; it must be from the application of this chapter; it must be suffered directly by the property in question; and evidence of variance granted under similar circumstances shall not be considered.
C.
In granting variances and modifications, the Board of Commissioners may impose such conditions as will, in its judgment, secure substantially the objectives of the standards or requirements so varied or modified.
