A nonconforming structure may be expanded one time to provide additional area not to exceed twenty percent (20%) of the floor area or land area as it existed at the date of adoption of this title. Application for such expansion shall be handled by level III processing procedures according to the following provisions.
A permit for expansion of a nonconforming use in no way removes the nonconforming status. All provisions relating to regulations and abandonment of a nonconforming use still apply.
A. Expansion of a nonconforming use shall be a conditional use. The provisions of sections 10-9-1 through 10-9-6 of this title shall apply.
B. In addition to the general criteria of section 10-9-6 of this title, the following criteria shall be met:
1. The proposed increase does not materially increase noise, odor, traffic, or other adverse effects on surrounding property which conforms to the provisions of the use zone applicable to the property.
2. The proposed increase shall not exceed the setbacks required for the principal use listed in the zone even though other portions of the existing structure may exceed the required setbacks.
C. In addition to the conditions of approval listed in section 10-9-5 of this title, the commission may place the following conditions on the expansion of a nonconforming structure: (Ord. 667, 9-24-1984)
1. If the nonconforming use is in a residential zone, the subject property, the expansion, and/or the original structure, may be required to be upgraded or modified so as to conform more closely to the residential structure characteristics of the surrounding property. (Ord. 667, 9-24-1984; amd. Ord. 925, 6-13-2005)
2. Increased setbacks, obscuring fencing, or other buffering may be required on the existing use as well as the expansion to provide additional protection to surrounding uses. (Ord. 667, 9-24-1984)
