1.   Lots in Two Districts. Where a district boundary line is established by this chapter or as shown on the zoning map divides a lot which is in single ownership and on record at the time of the adoption of the zoning ordinance, the use thereon and other district requirements applying to the least restricted portion of such lot under this chapter shall be considered as extending to the entire lot, provided the more restricted portion of such lot is entirely within one hundred (100) feet of said dividing line. The use so extended shall be deemed to be conforming.

   2.   Lots in Commercial or Industrial Districts Adjacent to Residential Districts. Where a lot in a commercial or industrial district abuts a lot in a residential district, there shall be provided along such abutting lines a minimum yard of twenty-five (25) feet.

   3.   Front Yard Transition. Where the frontage on one side of a street between two (2) intersecting streets is zoned partly as residential and partly as commercial or industrial, the front yard depth in the commercial or industrial district shall be equal to the required front yard depth of the residential district.

   4.   Garage Entrances. No public or private garage for more than five (5) motor vehicles shall have an entrance or exit for motor vehicles within twenty (20) feet of an “R-1” or “R-2” district.

   5.   Parking Lots and Driveways Abutting Residential Districts. Whenever a parking lot or a driveway to a parking lot is established in other than a residential district so as to abut the side or rear line of a residential district, planted screenings, a solid masonry wall, or a substantial sightly fence not less than four (4) feet high and not more than eight (8) feet high shall be planted or constructed and maintained along said side or rear lot line up to, but not beyond, the setback building line of the district in which it is located. In addition, in all districts, the lighting, including any permitted illuminated sign, on any parking lot or driveway shall be arranged so that there will be no annoying glare directed or reflected toward residential districts.

   6.   Reversed Corner Lot Abutting Residential Districts. In the case of a reversed corner lot where the rear of a lot in a “C” district abuts upon the side of a lot in any residential district, there shall be a rear yard of not less than fifty percent (50%) of the rear yard requirement of the abutting residential district, provided further that where a public alley separates the rear of the lot in the “C” district and the side of the lot in any residential district, no rear yard shall be required.
