Except as hereinafter provided, buildings or other structures which do not conform with the requirements of this zoning ordinance for use, height, area of lot, off-street parking requirements, off-street loading requirements or setback may not be subject to major repairs, substantial alterations or extensions, nor may the use be changed unless and until all the requirements of this zoning ordinance have been fulfilled so far as they apply to the particular building or structure. Where it is proposed to improve an existing building or structure by major repairs, substantial alteration or extensions, or the use of an existing building or structure is proposed to be changed and the building or structure, together with the adjacent lot area, does not fulfill the requirements of this zoning ordinance for use, height, area of lot, off-street parking requirements, off-street loading requirements or setback, the Board of Zoning Appeals may recommend to Council modification of these requirements, provided the Board of Zoning Appeals determines that the recommended modified requirements will not have a more adverse effect upon the neighborhood than the existing nonconformities and are in harmony with the general intent of this zoning ordinance and will secure the general welfare and substantial justice in the promotion of public health, comfort, convenience, morals, safety and general welfare of the city.
