Under the County’s Zoning Code a business may be operated in a residential area of “Unincorporated St. Louis County” as long as it complies with the criteria for a “Home Occupation” which is defined as follows: “A business, commercial, or professional endeavor operated as a domestic activity carried on solely by members of a family who reside on the premises. These endeavors shall not offer any services to the general public, nor stock in trade or commodity on the premises, shall utilize no equipment except as is customary for purely domestic or household purposes, and shall not involve any signage or display which indicates use of the property for any purpose other than a dwelling from the exterior of the dwelling. The keeping of not more than two (2) roomers or boarders, the supervision of not more than four (4) children other than those residing on the premises, and the instruction or tutoring of one (1) student at a time, up to eight (8) students per day, shall each constitute a home occupation. Beauty or barber shops, convalescent or nursing homes, tourist homes, including bed-and-breakfast, music schools involving the instruction of more than one (1) student at a time, massage parlors, and motor vehicle repairs shall not be deemed home occupations.” For additional information on “Home Occupations” contact County Zoning Review at 314-615-2525 or 314-615-7814.
