The regulations set forth for home occupations shall apply to all residential dwelling units or residential accessory structures, irrespective of the zoning district. Should a residential use in the commercial zoning district fail to meet the conditions necessary to qualify as a home occupation, it is then considered a full commercial business and must comply with all regulations covering commercial establishments. These regulations do not apply to land uses which require conditional use permits in residential zones, which must go through a separate conditional use permit process. (1984 Code § 3-9-2)
