§ 6.02  ACCESSORY USES AND STRUCTURES.
   6.02.01   General.  Except as otherwise expressly provided in this zoning ordinance, accessory uses and structures are permitted in connection with any lawfully established principal use. Also, unless otherwise expressly stated, accessory uses are subject to the same regulations as the principal use.
   (A)   Time of Construction.  Accessory structures must be constructed in conjunction with or after the principal building. They may not be built prior to the construction of the principal building.
   (B)   Subordinate Nature.
      (1)   Accessory uses must be a subordinate part of a principal use and be clearly incidental to a principal use.
      (2)   Accessory structures must be of secondary importance and subordinate to the principal building on a site.
   (C)   Lot and Building Standards.  The lot and building standards of the base zone apply to principal and accessory structures, unless otherwise expressly stated.
   (D)   Building Coverage.  In RS and RU zones, the combined footprint of all detached, covered accessory structures may not exceed the footprint of the principal building, or 20% of the total area of the lot, whichever is less. In all other zones, a single detached, covered accessory structure may not have a larger footprint than the building footprint of the principal building.
   (E)   Height of Accessory Structures.  Unless otherwise expressly stated, accessory structures may not exceed 15 feet in height, or the height of the principal building on the same lot, whichever is less.
   6.02.02   Residential Garages.
   (A)   Each detached house, attached house, and two-unit building is limited to one freestanding, accessory garage.
   (B)   Residential garages must be located on the same lot as the principal building.
   (C)   Street-facing garage doors (whether on attached or detached garages) may comprise no more than 40% of the width of the front facade of the detached house, attached house, or two-unit building to which it is accessory. Such street-facing garage doors must be recessed at least five feet from the front facade. The intent of these standards is to prevent garages from being the dominant visual feature on the front of the building.
   (D)   Detached garages and carports must be set back at least five feet from rear property lines abutting alleys.
   6.02.03   Satellite Dish Antennas.
   (A)   Satellite dish antennas up to one meter (39.4 inches) in diameter are permitted as accessory uses in all zones. They must comply with all setback requirements of the subject zone, except as expressly indicated in § 9.08.09.
   (B)   Satellite dish antennas over one meter in diameter, up to three meters (118.2 inches) in diameter, are a permitted as accessory uses in all commercial and industrial zones, subject to the following standards:
      (1)   Antennas may be erected on the roof or attached to a principal building, provided the maximum height of the installation does not exceed the maximum allowable height of the subject zone or more than 15 feet above the top of the building on which it is to be located, whichever is less. Satellite dish antennas that are mounted on the roof or attached to the building must be located in a manner so as to detract as little as possible from the architectural character of the building.
      (2)   Satellite dish antennas must comply with all setback requirements of the subject zone, except as expressly indicated in 9.08.09.
      (3)   A building permit is required for each satellite dish antenna installation.
   (C)   Any satellite dish antenna not expressly permitted by paragraphs A and B above requires conditional use approval.
   6.02.04   Home Occupations.  The following standards apply to permitted home occupations:
   (A)   No persons other than members of the household residing in the premises may be engaged in such operation.
   (B)   The use of the dwelling unit for the home occupation must be clearly incidental and subordinate to its use for residential purposes by its occupants. Not more than 25% of the gross floor area of any one floor of the dwelling unit (including the basement or cellar) may be used in the conduct of the home occupation.
   (C)   A home occupation may not change the outside appearance of the building or premises in which it is located and no visible evidence of the conduct or activity of a home occupation may be seen from the exterior of the building that is being utilized in part for any purpose other than that of a dwelling unit, except that a name plate may be permitted, as regulated by Article 10.
   (D)   Home occupations may be conducted only within dwelling units. No activities related to home occupations may be conducted within accessory buildings.
   (E)   Home occupations may not displace any required off-street parking spaces.
   (F)   There may be no exterior storage of any materials on the premises.
   (G)   The retail sale of goods is not permitted on the premises in connection with such home occupation.
   (H)   No traffic may be generated by such home occupation in greater volumes than would normally be expected in a residential neighborhood.
   (I)   No equipment or process that creates noise, vibration, glare, fumes, odors, or electrical interference detectable to the normal senses off the lot in which the dwelling is located may be used in such home occupation. In the case of electrical interference, no equipment or process that creates visual or audible interference in any radio or television receivers off the premises, or causes fluctuations in line voltage off the premises, may be used.
