  • (1) Residential Uses. No lot, building, or structure shall be used or appear to be used for commercial purposes and shall not involve the conduct of a business nor contain commercial or industrially rated equipment not customarily used in connection with a residential occupancy, nor be used for the storage of vehicles, equipment, or materials not customarily incidental to the residential use.

  • (2) Alternative Energy FAR Bonus in the R-1 Zone. Single-family dwelling units in the R-1 Zone are eligible for a 0.05 FAR bonus for providing renewable energy sources. The maximum FAR for the R-1 Zone with the renewable energy bonus is 0.50. The renewable energy sources must provide 50% or greater of a parcel's annual energy requirements.

    • (i) Renewable energy sources include at least one component from (A) and one component from (B) below:

      • (A) Either solar water heating or tankless water heater; and

      • (B) On-site solar photovoltaic or small wind energy applications to provide the remaining renewable energy requirement.

    • (ii) The FAR bonus area shall be incorporated as a one story element in the form of either, but not limited to, a detached accessory building, or incorporation of a front wing, rear wing, side wing, or combination of wings.

  • (3) Architecture. The architecture and general appearance of the building shall be in keeping with the character of the neighborhood and such as not to be detrimental to the general welfare of the neighborhood in which they are located. For R-1 zoning, all construction shall utilize Design Guidelines for considerations and recommendations regarding characteristic architectural styles and prevailing neighborhood character.

  • (4) Massing. All residential additions, alterations, and modifications shall to the greatest extent possible, avoid excessive massing of the primary structure, through means of varying rooflines, elevations, and other architectural elements (see Figure 9.3.1).

  • (5) Multiple-Family Building Placement and Design.

    • (i) Multiple-family buildings shall be designed and located on the site in a manner that avoids long, continuous building walls or "barracks-like" rows of structures that create a "canyon effect." Where multiple units share a common driveway, parking court, or alley, ample space shall be provided to provide vegetation, i.e., shrubs and trees where feasible. Rows of adjacent garages shall be enhanced by architecturally recessing some or all of the garage doors, adding vegetation, or using some other means to lessen the undesirable visual effect of long unbroken planes of garage doors especially where visible from a public right-of-way (see Figure 9.3.2).
  • (ii) No multifamily buildings shall exceed 50 feet in any dimension without architectural articulation of the building façade or mass in order to avoid large, unbroken areas.

  • (iii) Significant wall articulation (i.e., insets, canopies, wing walls, trellises etc.) and the inclusion of elements such as balconies, porches, arcades, dormers, and cross gables shall be used to avoid the box-like appearance of long and unbroken façades, flat walls, and roofs of excessive visual prominence.
