The regulations set forth in this section qualify, supplement, or modify the area and height regulations set forth elsewhere in this chapter.

   1.   Lot Area and Width. Any lot of record at the time of passage of the Zoning Code having less area or width than herein required may be used for a single-family dwelling where such uses are permitted as provided in this chapter; provided, however:

      A.   A lot of record at the time of passage of the Zoning Code having a lot width of 50 feet or less shall maintain the required side yard on each side of the dwelling, but such yard shall not be less than five feet.

      B.   A lot of record at the time of passage of the Zoning Code having a lot depth of 100 feet or less may have the required rear yard reduced to not less than 20 feet.

   2.   Yards.

      A.   Where 30 percent or more of the block front is improved with buildings, then no part of any new building shall project beyond a line joining the two adjacent corners of the buildings on either side thereof or, where there is a building on only one side, beyond a line projected from the corresponding adjacent corners of the two nearest buildings, except that no building shall be required to provide a front yard greater than that required for the district in which it is located. Where an official line has been established for future widening or opening of a street upon which a lot abuts, then the depth of a front or side yard shall be measured from such official line.

      B.   In the case where the block front improved with buildings amounts to less than 30 percent of the total number of lots, including vacant lots, on one side of the street between two intersecting streets, the required minimum yards of the district shall be observed.

      C.   Buildings on through lots shall provide the required front yard on both streets.

      D.   The required side yard on the street side of a corner lot shall be not less than 50 percent of the front yard required on the lots to the rear of the corner lot, and no accessory building shall project beyond the required front yard on either street.

   3.   Use of Public Right-of-Way. No portion of the public road, street, or alley right-of-way shall be used for display purposes or to provide any parking or loading space required by this chapter.

   4.   Temporary Building. Temporary buildings with construction work may be permitted in any district during the period that the construction work is in progress, but such temporary buildings shall be removed within 30 days after completion or abandonment of the construction work.

   5.   Accessory Buildings. Accessory buildings and uses customarily incidental to that of the main building may be erected or established as permitted, provided they comply with the following:

      A.   No accessory building shall be located within two feet of any side or rear lot line, and shall not be located within five feet of any alley line.

      B.   Accessory buildings in any district shall not occupy more than 30 percent of the required yards.

      C.   No accessory building is permitted within the limits of the front yard.

      D.   No accessory building shall be used for dwelling purposes.

      E.   Any open unenclosed or uncovered steps, ground level patios, eaves not more than two feet in width, or concrete slab driveways may project into a required yard.

      F.   Accessory buildings attached to or connected to the principal building by a breezeway shall be considered to be a part of the principal building and must meet the yard requirements of the principal building.

      G.   Satellite television receptions discs shall be considered to be an accessory building and, as such, shall not be located within a front yard.

      H.   Any accessory building built on a residential lot without a residential dwelling shall be at the discretion of the Council. This shall include the type of accessory building, and composite materials of the accessory building.

   6.   Building Height. The height regulations shall not apply to television and radio towers, church spires, belfries, monuments, farm buildings, tanks, water and fire towers, stage towers or scenery lofts, cooling towers, grain elevators, ornamental towers and spires, chimneys, elevator bulkheads, drilling rigs, conveyors, flagpoles, and other pertinent mechanical apparatus which may be erected to any height not in conflict with any other applicable regulations.
