Except as otherwise provided herein, the lawful use of a building existing at the effective date of this chapter may be continued although the use does not conform to the provisions hereof. If no structural alterations are made, a nonconforming use of a building may be changed to another nonconforming use of the same or of a more restricted classification. Whenever a nonconforming use has been changed to a more restricted use or to a conforming use, the use shall not thereafter be changed to a less restricted use. The nonconforming use of a building may be hereafter extended throughout those parts of a building which were lawfully and manifestly arranged or designed for the use at the time of the enactment of this chapter.
