The lawful use of a building existing at the time of the adoption of this section, although such use does not conform to the regulations specified by this Zoning Code for the district in which such building is located, may be continued. Any such use may be extended throughout any parts of a building which were manifestly arranged or designed for such use at the time of adoption of this Zoning Code, but no such use shall be extended to occupy any land outside such building. If no structural alterations are made, a nonconforming use of a building may be changed to another nonconforming use which, in the opinion of the Planning and Zoning Commission, either by general rule adopted by the Commission or on a specific finding on appeal in a particular case, is of the same or of a more restricted nature.
