(A) Expansions. A nonconforming structure cannot be expanded, except as required by law, unless such expansion results in elimination of the nonconformity.
(B) Maintenance, repair, and alterations. A nonconforming structure may be regularly maintained and repaired. Alterations without expansion are permitted if they improve the appearance or stability of the structure.
(C) A building or structure which does not conform to the yard regulations applicable to the zone in which such building or structure is located may be structurally altered only when:
(1) The alteration causes the building or structure to conform to the applicable yard regulations;
(2) The alteration or enlargement does not project into any required yard; or
(3) The alteration or enlargement is an extension of that portion of the existing building or structure that encroaches into a required yard; provided, however, the alteration or enlargement cannot extend into the required yard farther than the existing portion and cannot have an area greater than 50% of the area of the existing portion within the required yard (see Figure 110-1). This allowance may only be utilized once on a property; future alterations or enlargements after the initial 50% allowance has been used on a property may not encroach into the required yard.
