It is the intent and purpose of the City Council, in adopting this chapter, to regulate those activities which, in the most technical sense, have business or commercial characteristics but which, because of the manner in which they are conducted or the purposes for which they are being operated, are truly noncommercial in nature. Said regulations are intended to prevent the expansion of such noncommercial operations into truly commercial operations and to regulate the method of conducting the activity so that it will be confined to a noncommercial type of operation. It is the purpose of this chapter to prevent such activities from unfairly competing with licensed revenue-producing commercial and business enterprises; to prevent the conduct of commercial enterprises upon other than commercially zoned property; and to curb the evasion of business license taxes. (Ord. 2408 § 1, 1990; Ord. 1218 § 1; prior code § 18.301).
