§ 155.141 RESIDENTIAL DISTRICT (R-20).
   (A)   Intent. The R-20 Residential District is established for residential areas where public services, such as public water and sewer, may not be available; however, housing units are located on one-half acre lots or larger, often within established subdivisions. Because housing units are generally closer together than in the R-A Residential-Agricultural District, there are more restrictions on uses that might infringe on neighboring homeowners.
   (B)   Dimensional requirements.
      (1)   Lot size. Thirty thousand square feet shall be the minimum lot area per dwelling unit or any other alternative as described in § 155.142.
      (2)   Lot width. One hundred feet shall be the minimum width of each lot. The measurement shall be made from one side property line to the other at the building setback line.
      (3)   Front yard setback. Thirty feet shall be the minimum setback of the principal structure, measured from the nearest point of the building and the right-of-way line.
      (4)   Side yard setback. Fifteen feet shall be the minimum side yard for each principal building, measured from the nearest point of the building and the side lot line.
      (5)   Rear yard setback. Thirty feet shall be the minimum rear yard for each principal building, measured from the point of the building nearest the rear lot line and the rear lot line.
      (6)   Accessory buildings. Accessory buildings shall be limited to the rear yard of a lot containing a principal building. These buildings shall not be located within 25 feet of any street right-of-way or within ten feet of any lot line not a street right-of-way line.
         (a)   Accessory buildings may be located in the front of side yard provided the lot is used for single-family purposes and is greater than one acre in size (area). In such a case, the residential accessory building shall be set back from the road right-of-way a minimum of 100 feet and 25 feet from any other lot line.
         (b)   Residential carports may be permitted in the side yard of a single-family dwelling provided such carports meet the side yard setback of a principal structure for the applicable zoning district. For the purposes of this section a RESIDENTIAL CARPORT shall be defined as an accessory building consisting of a roof where the side walls are open and where the purpose of such a structure is to provide covered parking for noncommercial (passenger) motor vehicles. The storage of materials or equipment, other than motor vehicles, in a residential carport is prohibited if the carport is not located in the rear yard.
      (7)   Off-street parking. Requirements specified in §§ 155.050 through 155.054 of this chapter.
   (C)   Dimensional requirements, two-family dwelling.
      (1)   Lot size. The minimum lot size for two-family dwellings shall be twice what is required for the underlying district. However, when these units are served by an individually owned septic tank system, the lot size shall be determined by the County Health Department. In no case shall a unit served by an individually-owned septic tank system have a lot area less than 20,000 square feet.
      (2)   Lot width. Eighty feet shall be the minimum width of the first dwelling with an additional 20 feet for the second unit.
      (3)   Front yard setback. Thirty-five feet shall be the minimum setback of the principal structure, measured from the nearest point of the building and the right-of-way line.
      (4)   Side yard setback. Ten feet shall be the minimum side yard for each principal building, measured from the nearest point of the building to the side lot line for duplex units (two-unit dwellings).
      (5)   Rear yard setback. Twenty feet shall be the minimum rear yard for each principal building, measured from the point of the structure nearest the rear line and the rear lot line.
      (6)   Accessory buildings. Accessory buildings shall be limited to the rear yard off lot containing a principal building (excluded from the front and side yards). These buildings shall not be located within ten feet of any street right-of-way or within five feet of any lot line not a street right of way.
      (7)   Off-street parking. Requirements specified in §§ 155.050 through 155.053 of this chapter.
