§ 150.20  ANTI-MONOTONY STANDARDS FOR SINGLE-FAMILY DWELLINGS.
   The following standards and definitions shall apply to the construction of all new single-family detached dwellings within the Village after the effective date of this section.
   (A)   Definitions. The words contained in this section shall have the common meanings ascribed to them or such meanings as are contained within other sections of the Village Code, provided, however, that the following words shall be interpreted to mean as follows:
      ADJACENT LOTS. Adjacent lots shall be lots which adjoin or share property lines or lots in which, although separated by a street, the front property lines overlap another by more than 30%.
      STREETSCAPE. A streetscape is the facades of single-family dwellings on both sides of a street. The length of a streetscape shall be limited to no more than 20 lots per side of a street. When more than 20 lots per street side exist without an intervening cross street, the Village shall, through 1 of its officers or employees, establish those lots which shall constitute a separate streetscape. In making that determination, the official shall consider that configuration of lots which shall be most influenced and affected by adjacent lots. Where possible, physical demarcations such as topography, road configuration or landscaping shall be utilized in establishing the appropriate streetscapes. In general, the front orientation of the residence will determine the applicable streetscape.
   (B)   Similar elevations and/or facades prohibited on adjacent lots.  No 2 single-family dwellings of similar front elevation and/or facade shall be constructed or located on adjacent lots or on lots opposite each other. Further, single-family dwellings of similar front elevation and/or facade shall be separated by at least 2 lots, regardless of the side of the street the dwelling is located on; nor shall there be constructed or located single-family dwellings of similar front elevation and/or facade constituting more than 25% of the single-family dwellings in any streetscape.
   (C)   Identical footprint prohibited on adjacent lots. No 2 single-family dwellings with the identical footprint or mirrored footprint shall be constructed or located on adjacent lots or on lots opposite each other. Further, single-family dwellings with the identical footprint or mirrored footprint shall be separated by at least 2 lots, regardless of the side of the street the dwelling is located on; nor shall there be constructed or located single-family dwellings with the identical footprint or mirrored footprint constituting more than 25% of the single-family dwellings in any streetscape.
   (D)   Criteria. Designated Village officials shall consider the following enumerated factors in determining whether front elevations or facades shall be deemed to be similar. Front elevations and facades shall be deemed to be dissimilar when at least 1 of the delineated changes under the each of the following categories of roof lines, windows and construction materials and colors is made.
      (1)   Roof lines. To be considered dissimilar, the roof lines of 2 adjacent single-family dwellings, as seen from the front of the dwelling, shall be changed in at least 1 of the following ways:
         (a)   Changing gable roofs to hip roofs.
         (b)   Changing hip roofs to gable roofs.
         (c)   Providing an intersecting gable roof on the main gable roof, provided that the height of the intersecting roof is at least 35% of the height of the main roof.
         (d)   Providing an intersecting hip roof on the main hip roof, provided that the height of the intersecting hip roof is at least 35% of the height of the main roof.
         (e)   Subject to review by the designated Village official, a shed roof when used as a front porch roof for a minimum of 50% of the entire width of the house, excluding area of garage.
         (f)   Subject to review by the designated Village official, a substantial difference in roof line shall be deemed to exist if the front soffit is increased substantially and is combined with columns at least 6 inches in width other architectural features of a similar magnitude which reach the roof line of the highest story.
         (g)   Rotating gable roofs 90º on the building.
         (h)   On a tri-level residence or other building type which has 3 independent major roof areas, the changing of 2 out of the 3 roof lines shall be acceptable as a substantial change. Acknowledging certain design elements may prevent the changing of all 3 roof lines, it is desired that the roofs with the greatest impact on the streetscape be changed.
      (2)   The following changes to roof lines shall not be deemed sufficient to make adjacent structures dissimilar:
         (a)   Gable roof atop hip roof.
         (b)   Hip roof atop gable roof.
         (c)   Small gable or hip projections above windows.
         (d)   Change in soffit overhang or minor variations in eave height.
         (e)   Skylight and cupola.
      (3)   Windows.  To be considered dissimilar, the windows of 2 adjacent single-family dwellings shall be changed in at least 1 of the following ways:
         (a)   Changing from single windows to multiple window arrangement (ganged units).
         (b)   Changing from multiple window arrangement to single window.
         (c)   Changing the type of windows (e.g. casement to double hung).
         (d)   Providing a bay or bow window in the area of the predominant window.
      (4)   Where because of its size, location or design, 1 window is the predominant window on the front elevation or façade, if the size, location or type of that window is changed to render the dwelling dissimilar, then no other window need be changed.
      (5)   The addition or subtraction of muntin bars (dividing lights) shall not be deemed sufficient change to constitute a substantial change in windows.
      (6)   Construction materials or colors. To be considered dissimilar, the construction materials of 2 adjacent single-family dwellings shall be changed in at least 1 of the following ways, provided that when materials are changed, the change must occur throughout the front facade or elevation for a minimum of 1 story in height:
         (a)   Changing the siding from horizontal to vertical.
         (b)   Changing the siding from vertical to horizontal.
         (c)   Four-inch exposure horizontal siding.
         (d)   Eight-inch exposure horizontal siding.
         (e)   Brick siding.
         (f)   Stone facing.
         (g)   Stucco/stuccato board and trim.
   (E)   In addition to the other requirements of this section, all residences constructed in R-1 and R-lx zoning classifications shall have on the front of the residence (defined herein as corner to corner across that front elevation of the residence) a minimum of 66 2/3% of the area exposed on that elevation covered in brick, brick siding, stucco, drivet (or similar materials approved by the Village) or stone facing excluding windows, doors and garage doors. Any material produced from vinyl or a wood based product or that is produced in sheets for application shall not satisfy the requirements of this section.
