§ 155.428  LOT DEVELOPMENT REQUIREMENTS.
   (A)   Minimum lot setbacks.  Building and structure setbacks are intended to provide for the adequate spacing of buildings and structures between property lines and to provide safe distances from road rights- of-way.  The following standards are the minimum setbacks for the listed uses; therefore, a building or structure can be constructed a greater distance from a property line or road right-of-way.

   (C)   Minimum lot widths (road frontage). 
      (1)   The minimum lot width is 100 continuous feet measured at the road right-of-way (if in curve, measure by arc length) on state or county existing maintained minor roads, as defined in this chapter (see below notes). When property fronts on a principal or minor arterial road, the minimum lot width measured at the road right-of-way must be a minimum of 350 continuous feet. When property fronts on a major collector, the minimum lot width measured at the road right-of-way must be a minimum of 150 continuous feet. (See Chapter 154 Appendix, § 29 for a complete list of major roads.)
      (2)   The minimum lot width for commercial, industrial, and multi-family developments is 150 continuous feet.
      (3)   The minimum lot width may be reduced where specified within this chapter or for the following cases:  (NOTE: Lots located along street curves shall have their frontage measured along the radius of the right-of-way.)
         (a)   Sixty-five continuous feet for lots off of internally accessed minor streets created in new subdivisions approved by the Planning Commission that front on a road that is curb and gutter design;
         (b)   Forty continuous feet for lots off of internally accessed minor streets created in new subdivisions approved by the Planning Commission that front on a road that is curb and gutter design with connection to public water and sewer;
         (c)   Sixty continuous feet for lots off of internally accessed minor streets created in new subdivisions approved by the Planning Commission in which a right-of-way is indicated for future phases (50 continuous feet where road is to be curb and gutter design).  The plat must indicate “Right-of- Way Only.  No construction proposed.”  NOTE:  The right-of-way and remaining parcel must stay in the developer’s/property owner’s name indicated at time of submittal, until the proposed road is built, inspected, and receives final plat approval. A certificate of occupancy cannot be issued for any structures proposed on the land indicated as future development until the road has been constructed and receives final plat approval (see Appendix C - Exhibit 5);
         (d)   Thirty-five continuous feet at the road right-of-way and the minimum lot width measured between the side property lines at 50 feet from the road right-of-way for lots that front completely within the curvature of a cul-de-sac for lots created in new subdivisions approved by the Planning Commission (see Appendix C - Exhibit 4);
         (e)   No frontage requirement for lots dedicated as open space or unmanned utilities.    
   (D)   Notes.
         (1)   Lots (“flag lots”) in which the lot width becomes smaller than the minimum road frontage (required above) and then increases to create a rear parcel are prohibited (see Appendix C - Exhibits 6A and 6B).
         (2)   Exemption standards as specified in § 154.013 are applicable to the lot width provisions of this chapter.
