"Home occupation" means any use conducted entirely within the dwelling and carried on by the members of the family, but may include one employee outside the family which use is clearly incidental and secondary to the dwelling for dwelling purposes and does not change the character thereof and in connection therewith there are no commodities sold from the premises, except that which is produced thereof, provided that the same does not involve more than one-fourth of the total square footage of the dwelling. The conducting of a hospital, tea room, tourist home, animal hospital or any use generating traffic volumes greater than that generated by typical residential use shall not be deemed to be a home occupation. (Ord. 618 § 2, 1999: Ord. 523 § 1(part), 1989)
