When authorized as permitted uses in the zoning district in which they are proposed to be located, dwellings with common party walls may be constructed on a sublot and separately conveyed subject to compliance with the subdivision regulations of the governing authority and with all of the following conditions:

A. Site Requirements.

1. Each sublot shall be located in a recorded subdivision lot which shall contain an area of not less than six thousand square feet.

2. The allowable number of sublots shall be determined by dividing the gross area of the platted lot by the density limits of the zoning district. In no case shall a sublot have an area of less than two thousand square feet nor more than one dwelling unit thereon. Neither the board of adjustments nor the zoning administrator shall have authority to vary this provision. For density computation, the gross area of the lot shall not be reduced by the area of drainage ways dedicated to the governing authority.

B. Building Limitations. The yard, height, and area requirements of the district shall apply to the entire area of the platted lot or of the developed tract.

C. Use of Common Area. When the proposed sublots are located in a subdivision which also contains areas to be held in common ownership by the owners of lots or sublots, such common area may be used for required and supplementary parking, accessory buildings, and recreational facilities.

D. Private Access Ways. Private access ways may be used for vehicular ingress and egress when shown on the preliminary plat, provided they are constructed in accordance with standards and specifications of the city council. (Ord. 523 § 1(part), 1989)
