Dimensional variance. In granting a dimensional variance, the hardship that will be suffered by the owner of the subject property if the dimensional variance is not granted, shall amount to more than a mere inconvenience, meaning that the relief sought is minimal to a reasonable enjoyment of the permitting use to which the property is proposed to be devoted. The fact that a use may be more profitable or that a structure may be more valuable after the relief is granted shall not be grounds for relief.
