"Nonconformance. (a) Building-mounted systems: [1] If a building-mounted system is to be installed on any building or structure that is nonconforming because its height violates the height restrictions of the zoning district in which it is located, the building-mounted system shall be permitted so long as the building-mounted system does not extend above the peak or highest point of the roof to which it is mounted and so long as it complies with the other provisions of this chapter. [2] If a building-mounted system is to be installed on a building or structure on a nonconforming lot that does not meet the minimum setbacks required and/or exceeds the lot coverage limits for the zoning district in which it is located, a building-mounted system shall be permitted so long as there is no expansion of any setback or lot coverage nonconformity and so long as it complies with the other provisions of this chapter. (b) Ground-mounted systems. If a ground-mounted system is to be installed on a lot containing a structure that is nonconforming because the required minimum setbacks are exceeded, the proposed system shall be permitted so long as the system does not encroach into the established setback for the lot. If a ground-mounted system is to be installed on a lot that is nonconforming because it violates zoning district requirements other than setbacks, then a variance must be obtained for the proposed installation."
