(a) A nonconforming use existing at the time of the passage of the Zoning Ordinance (Ordinance 2812, passed November 13, 1922) may be continued. A nonconforming use shall not be extended except as authorized by Section 1375.01, but the extension of a use to any portion of a building, which portion was arranged or designed for such nonconforming use at the time of the passage of the Zoning Ordinance, shall not be deemed the extension of a nonconforming use.
(b) A building arranged, designed or devoted to a nonconforming use at the time of the passage of the Zoning Ordinance may not be reconstructed or structurally altered to an extent exceeding in aggregate cost, during the ten-year period, sixty percent of the assessed value of the building, unless the use of such building is changed to a conforming use. A nonconforming use may not be changed unless changed to a more restricted use. A nonconforming use if changed to a conforming use may not thereafter be changed back to any nonconforming use. A nonconforming use if changed to a more restricted nonconforming use may not thereafter be changed unless to a still more restricted use.
(c) For the purpose of this Zoning Code a use shall be deemed to be changed if changed from a use included in a subdivision of a use class to a use not included in such subdivision. For the purpose of this Zoning Code a nonconforming use shall be deemed to be changed to a more restricted use if the use to which such nonconforming use is changed is a use included in a subdivision of a use class that, in the arrangement of classes and subdivisions in the classification of uses, precedes the subdivision in which such nonconforming use is included.
