(a) Except as provided in Section 347.06 and Chapter 351, a use of building or land lawfully existing on the effective date of this Zoning Code or of any amendment or supplement thereto, or for which a permit has been lawfully issued, may be continued even though such use does not conform to the provisions of this Zoning Code for the use district in which it is located, but no enlargement or expansion shall be permitted except as a variance under the terms of Chapter 329, and no substitution or other change in such nonconforming use to other than a conforming use shall be permitted except by special permit from the Board of Zoning Appeals. Such special permit may be issued only if the Board finds after public hearing that such substitution or other charge is no more harmful or objectionable than the previous nonconforming use in floor or other space occupied, in volume of trade or production, in kind of goods sold or produced, in daily hours or other period of use, in the type or number of persons to occupy or to be attracted to the premises or in any other characteristic of the new use as compared with the previous use.
(b) The enactment of this Zoning Code shall not in any way affect the legality or previous orders requiring the discontinuance of nonconforming uses nor extend the time limit already established when existing nonconforming uses shall be discontinued.
