An accessory building or structure which exceeds six feet in height shall be erected in a required yard or court only as provided herein.

   1.   Principal Building Area. An accessory building or structure which is located partially or entirely within the principal building area of the lot (the lot minus the required yards and courts) whether attached or detached to the principal building shall be subject to the regulations applicable to the principal building.

   2.   Lot Lines. Accessory buildings shall have no portion of the structure, including overhang, less than two feet from any lot line, and on a corner lot they shall conform to the setback regulations on the side street.

   3.   Connection. Accessory buildings, except buildings housing animals or fowl, may be erected as a part of the principal building or may be connected thereto by a breezeway or similar structure; however, said building shall then comply with all yard requirements for a principal building.

   4.   Garage. The garage for any principal building on a lot abutting an alley may be located in a rear or side yard area which abuts the alley; providing, however, that such garage building shall comply with the following requirements:

      A.   The detached garage shall be set back no less than two feet from a party lot line or alley line, except when any part of such building is within 50 feet of any street or public place upon which the lot abuts, such building shall be at least six feet from any lot line which serves as the front portion of a side lot line for any adjoining property; or shall be located no closer than 24 feet to any garage or principal building which is located on the opposite side of the alley; whichever is the greater requirement.

      B.   The attached garage building shall be considered an extension of the principal building and shall comply with all minimum yard requirements for the principal building other than the exception herein permitting the garage entrance to be located near the alley, i.e., an attached garage facing an alley which abuts a side lot line shall not encroach into the required front or rear yards; an attached garage facing an alley which abuts a rear lot line shall be set back from the side lot lines no less than the requirements for the principal building.

      C.   The detached garage building shall not exceed one story or 15 feet in height.

   5.   Yard Area. Accessory buildings and structures, regardless of height, which are constructed above the normal ground surface in any required yard area shall not occupy more than 30 percent of the yard area in which it is located; however, this regulation shall not be interpreted to prohibit the construction of a two-car garage not to exceed 576 square feet gross building area. An accessory building which is not a part of the main building shall be a distance of at least 10 feet from any other building on the lot including the principal building.
