A. Continuance Of Use: The lawful use of a building existing at the time of the original adoption of this title may be continued although such use does not conform with the provisions hereof, and such use may be extended throughout the building; provided, no structural alterations, except those required by law or the provisions of this code, are made therein.
B. Change To Other Nonconforming Use: If no structural alterations are made, a nonconforming use of a building may be changed to another nonconforming use of the same or more restricted classification. The foregoing provisions shall also apply to nonconforming uses in districts hereafter changed. Whenever a nonconforming use of a building has been changed to a more restricted use or to a conforming use, such use shall not thereafter be changed to a less restricted use. (Ord. 252, 12-7-1955)
