Any enlargement of a nonconforming structure containing a conforming use shall comply with all required setbacks in this UDO and other applicable regulations, and may not create any additional dwelling units, create new nonconformities, or increase the extent of existing nonconformities. A nonconforming structure shall not be moved, in whole or in part, to another location on or off the parcel of land on which it is located, unless upon relocation it conforms to the requirements of this UDO.
   B.   Nonconforming Structures Containing a Nonconforming Use. A nonconforming use that is contained within a nonconforming structure is subject to subsection 10.3: Nonconforming Uses. Nonconforming structures shall meet the requirements defined in Section 10.4.A above.
   C.   Minor Repairs and Maintenance. Minor repairs to, and routine maintenance on, nonconforming structures shall be allowed. Minor repairs and routine maintenance shall mean repairs and maintenance that are necessary to maintain a nonconforming structure in a safe condition and to protect against hazards to the safety of surrounding areas and uses. Major repairs, defined as repairs exceeding fifty (50) percent or more of the value of the nonconforming structure, are subject to Section 10.4.D below.
