(A) Normal maintenance of a building or other structure containing a nonconforming use is permitted, including necessary nonstructural repairs and incidental alterations which do not extend or intensify the nonconforming use.
(B) No structural alteration shall be made in a building or other structure containing a nonconforming use, except in the following situations:
(1) When the alteration is required by law;
(2) When the alteration will actually result in eliminating the nonconforming use; or
(3) When a building in a residence district containing residential nonconforming uses may be altered in any way to improve livability; provided no structural alteration shall be made which would increase the number of dwelling units or the bulk of the building.
