470-26.03 and
470-26.04 of this chapter to the contrary, be permitted to be extended, enlarged, altered, remodeled, modernized, rebuilt, or restored, provided that (1) the specific nonconformity created when the right-of-way was acquired is not increased; and (2) all such extended, altered, remodeled, modernized, rebuilt, or restored buildings and structures shall conform to all other requirements of this chapter. However, the provisions of this section shall not apply to buildings or structures which have a setback from the new right-of-way line of less than 50% of the required minimum setback; such buildings and structures may be extended, enlarged, altered, remodeled, or modernized only if first approved by the Board of Appeals as is provided in §
470-26.03, and may be rebuilt or restored only if first approved by the Board of Appeals as is provided in §
