§ 17.40.020. Modification of nonconforming uses.
Upon the issuance of a special permit from the city council, nonconforming uses may be modified as follows:
A.
Change or substantial extension of the use;
B.
Change from one nonconforming use to another, less detrimental, nonconforming use.
The city council may award a special permit only if it determines that such change or extension shall not be substantially more detrimental than the existing nonconforming use to the neighborhood.
