The exterior design or appearance of a building shall not be excessively similar to that of any other building existing or for which a permit has been issued, or to that of any other structure included in the same application, on a lot abutting on the same street and within 150 feet of the proposed lot, with respect to one or more of the following features of exterior design and appearance:
(a) Exterior Design. The facades of a dwelling, particularly the street elevation, shall not be apparently identical. There shall be variations in the size and arrangement of doors, windows, entrances, porches, dormers or other openings and breaks.
(b) Reverse Arrangements. Reverse arrangements shall not be approved unless there are changes in the elements of the facade. Variety shall be encouraged by different composition of the main sections or wings of the dwelling.
(c) Other Significant Features. Other significant features such as, but not limited to, exterior materials, roof line or height, or other design elements, shall not be apparently identical, provided, however, that a finding of excessively similar design shall include the fact that it is of such nature as to produce one or more of the harmful effects set forth in Section 1327.02
