A duplex district shall provide most of the desirable residential characteristics attributed to single-family districts. It has useful applications as a buffer zone along major streets and bordering neighborhood shopping centers. (Prior code § 8-1.5(a))

Within the A-2 district, no building, structure or premises shall be used and no building or structure shall hereafter be erected, structurally altered, replaced, or enlarged except for one or more of the following uses:

A. Any use permitted and as regulated in the R-1, R-2 and R-3 single-family districts;

B. Two-family dwelling (duplex). (Prior code § 8-1.5(b))

No main building shall exceed thirty-five feet in height. (Prior code § 8-1.5(c))

Within any A-2 district, no building or structure shall be constructed on any lot having a width of less than sixty-five feet and an area of less than seven thousand five hundred square feet. There may be more than one two-family (duplex) dwelling on any lot, provided there is not less than seven thousand five hundred square feet of lot area for each two-family dwelling (duplex). This lot width and area requirement shall not apply to the building of a two-family dwelling on lots of less than seven thousand five hundred square feet in area where existing boundaries of such lots were actually established and of record in the Bureau of Conveyances and/or Tax Office of the state prior to the enactment of the ordinance establishing the use of zone district. (Prior code § 8-1.5(d))

A. Front Yard. There shall be a front yard of not less than fifteen feet in a class A-2 two-family district from any setback line for street widening purposes, and if no such line exists, then from main street boundary or front boundary. An attached garage, carport, or other permitted accessory use shall provide and maintain the same front yard setback as required for the main building. A detached accessory building, any portion of which is located to the side or front of the main building, shall not be less than five feet from such main building and not nearer to the side lot line than the width of the front yard required for the main building.

B. Side Yard. There shall be a side yard on each side of the main two-family (duplex) dwelling of six feet. In the case of a two-story two-family (duplex) dwelling not exceeding thirty-five feet in height, the minimum side yard space shall be ten feet. An attached garage, carport, or other permitted accessory use shall provide and maintain the same yard spacing as required for the main two-family (duplex) dwelling.

C. Rear Yard. There shall be a rear yard of not less than twenty feet in an A-2 two-family (duplex) district from the common boundary line. A detached permitted accessory building, any portion of which is located to the rear of a main two-family (duplex) building, shall be located not nearer than six feet to such main building; provided, however, this construction shall not reduce the depth of the rear yard to less than twenty feet. (Prior code § 8-1.5(e))
