Permitted off street parking lots, off street loading facilities, and outdoor sales in zoning districts where such outdoor sales are permitted, need not be enclosed.
   B.   One Principal Building Per Lot: Not more than one principal building shall be located on any lot except that:
      1.   With the exception of buildings located in the FR, R-1, SR and R-2 Districts, more than one principal building may be located on a lot subject to all principal buildings having frontage along a public street.
      2.   Lots in the RP, BP, M-1, M-2, AG, AG-2, AG-5, AG-20, A, OS, NOS, and EI Districts may have multiple buildings on a single lot regardless of street frontage and subject to meeting all other zoning regulations.
      3.   This section does not apply in instances where multiple buildings on a lot are regulated elsewhere in this title.

   D.   Hazardous Waste Prohibition: It is unlawful to permanently store or dispose of hazardous waste within Salt Lake City except for incineration of hazardous waste as allowed in the industrial M-2 Zoning District.
   E.   Flag Lots In Nonresidential Districts: In the CG, BP, RP, M-1 and M-2 Districts, flag lots shall be permitted, subject to subdivision regulations; provided, that:
      1.   As part of new subdivisions or through the planned development process only when the flag lot is proposed at the rear of an existing parcel;
      2.   The flag lot access strip shall have a minimum of twenty four feet (24') of frontage on a public street; and
      3.   The City subdivision review process determines the following:
         a.   It is not desirable or necessary to extend a public street to access the parcel, and
