The following provisions apply in all Residential Districts.
(Ord. 86-382, 12-22-1986)

11-8A-2: HOME OCCUPATIONS:

   A.   Scope: The home occupation regulations set forth herein are intended to allow residents to engage in home based business activities, while ensuring adjoining properties will not be adversely impacted and character and livability of the surrounding area compromised. Home occupation regulations establish performance standards rather than lists of allowable uses which are considered home occupations. The determination as to whether or not an activity constitutes a home occupation shall be made by the City Administrator or their designee. A home occupation may not commence until it has been approved and authorized by the City.
   B.   Regulations Specified: Home occupations shall be governed by the following regulations:
      1.   The operator of a home occupation shall be a full time permanent resident of the dwelling unit.
      2.   Home occupations shall not employ more than one person who does not reside on the premises.
      3.   Home occupations shall be conducted entirely within enclosed structures, and there shall be no exterior storage of equipment or materials used.
      4.   There shall be no visible evidence of the conduct of such occupation in the outside appearance of the premises.
      5.   Any need for parking generated by the occupation shall be met off the street.
      6.   No home occupation shall involve construction features or the use of electrical or mechanical equipment that would change the fire rating of the structure or of the fire district in which the structure is located.
      7.   It is clearly incidental or subordinate to the primary residential use of the property.
      8.   It shall be conducted in such a manner that it is compatible and will not adversely impact established residential character of the neighborhood in which it is located.
      9.   No signs advertising a product, service, business or occupation are permitted, with the exception of a one square foot sign for any home occupations, which are required to display one by the Federal or State government (see section 10-20-13 of this Code).
      10.   It shall not create any nuisance, hazard or other offensive condition, such as increased traffic, noise, smoke, fumes, dust, odor, electric or mechanical equipment interference.
      11.   No mechanical equipment is to be used, except such as is normally used for purely domestic or household purposes.
      12.   No more than twenty five percent (25%) of the footprint of the principal structure or five hundred (500) square feet (whichever is less), may be devoted to the home occupation.
      13.   Home occupations must comply with all City ordinances, rules and regulations applicable to Residential or Residentially zoned areas, including, but not limited to, performance standards (such as, but not limited to, noise, vibration, odor, nuisances, lighting, driveways, commercial and recreational vehicles, etc.).
      14.   Wholesale, retail, manufacturing, boarding, repair or warehouse business shall be prohibited unless they comply with all provisions in this section, chapter 17, “Performance Standards”, of this title, and all other applicable City rules, ordinances and regulations, or unless they are conducted entirely using external communication devices (such as, but not limited to, phone, electronic mail, facsimile, electronic meetings, Skype, etc.), regular United States Postal Service residential mail delivery or delivery vehicles limited to those normally servicing residential neighborhoods (such as, but not limited to, UPS, FedEx, etc.) and does not involve the receipt, sale, boarding, manufacturing or storage of merchandise or animals on the premises, including, but not limited to, kennels and shelters of any kind.
   C.   Prohibited Home Occupations: The following uses are expressly prohibited as home based businesses, unless they comply with all provisions in this section, chapter 17, “Performance Standards”, of this title, and all other applicable City rules, ordinances and regulations:
      1.   Any type of repair, body work, painting, assembly or storage of vehicles or equipment with engines (such as, but not limited to, motor vehicles, motorcycles, scooters, snowmobiles, outboard marine engines, lawnmowers, chain saws and similar equipment) or appliances (such as, but not limited to, washing machines, dryers and refrigerators) or any other work associated with equipment with engines and parts.
      2.   Dispatch centers where employees come to the site to be dispatched to other locations.
(Ord. 86-382, 12-22-1986)

11-8A-3: STANDARDS FOR NONRESIDENTIAL USES:

   A.   Yard Requirements: Yard requirements for nonresidential permitted and conditional uses, except permitted and conditional public uses and temporary uses, shall be the same as required for single- family detached dwellings in the same zoning district.
