Subtitle 2 - Designation and Adoption
Section 4-206 - Variances

(a)    By local law, a legislative body may specify in a zoning law the allowable modifications that may be made by a variance.
    (b)    The modifications in a variance:
        (1)    may be only of density, bulk, dimensional, or area requirements of the zoning law;
        (2)    may be only allowed where, owing to conditions peculiar to the property and not because of any action taken by the applicant, a literal enforcement of the zoning law would result in unnecessary hardship or practical difficulty as specified in the zoning law; and
        (3)    may not be contrary to the public interest.
