The lawful use of a building or trailer court existing on or before February 12, 1971, may be continued, although such use does not conform with the provisions of this title, and such use may be extended throughout the building or trailer court; provided, no structural alterations, except those required by law or ordinance, are made therein. If no structural alterations are made, a nonconforming use of a building or trailer court 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 or trailer court has been changed to a more restricted use or to a conforming use, such use shall not be thereafter changed to a less restricted use.
