§ 150.060 LOT REQUIREMENTS.
   (A)   Except as otherwise specified in this subchapter, all lots shall be subject to the lot requirements in Table IV-2 of this chapter.
   (B)    Number of principal buildings on a lot. Every principal building hereafter erected or structurally altered shall be located on a lot, and in no residential zoning district shall there be more than one principal building on a lot, except as provided in this section or elsewhere in this chapter. In the event that a lot is to be occupied by a group of two or more related principal buildings to be used for multi-family dwellings, institutional, or hotel purposes, there may be more than one principal building on the lot when adequate open space is provided between all buildings. The required minimum width of this open space shall be determined in relation to the height and length of each building wall and the placement of walls therein, as follows:
      (1)   If the wall contains one or more windows, the minimum width of the open space shall be 15 feet, plus two feet for each story in height, plus one foot for each 15 feet in length of the wall.
      (2)   If the wall contains no windows, the minimum width of the open space shall be five feet, plus one foot for each story in height, plus one foot for each 15 feet for the length of the wall.
   (C)   Lot frontage. In order to be considered a legal lot, a lot must have frontage on a public street or private lane. This frontage must be at least 30 feet in width.
   (D)   Combination of contiguous lots. When two or more lots are contiguous and are held in one ownership, they may be combined to create a single lot for purposes of meeting yard requirements to construct improvements. Upon construction of such improvements, the lot shall be considered one lot.
   (E)   Division of lots. No improved lot shall hereafter be divided into two or more lots and no part of a lot shall be sold unless all resultant lots conform to all lot requirements for the district in which the lots are located.
   (F)   Exception to minimum lot area and width. A lot of record that does not meet the minimum lot area and/or width requirements for the zoning district in which it is located may still be improved provided the lot has a lot width of at least 40 feet at the building line and is at least 5,000 square feet in area, and can provide side yards (when required) of at least five feet and can meet all other bulk requirements of this Ordinance.
   (G)   Lots developed with individual water and sewage systems. In any district where private water and sanitary sewage systems are used instead of public utilities, the minimum lot area, width and depth shall be subject to approval of the Zoning Administrator after conformance with County Health Department regulations. No building or structure served by a private sanitary sewer system shall be allowed within 300 feet of the high water level of Lake Vermilion.
   (H)   Lots for common lot line dwellings. Minimum lot area and lot widths for common lot line dwellings shall be as follows:
      (1)   If a common lot line dwelling contains two units, each lot shall be 1/2 the required lot area and lot width of the underlying zoning district.
      (2)   If a common lot line dwelling contains three or more units, each lot shall be a minimum of 2,000 square feet and have a minimum width of 20 feet.
