19.28.110 Single-Family Residential Design Guidelines and Principles.

Any new single-family residential house or addition to an existing house shall be generally consistent with the adopted single-family residential guidelines in Sections 19.28.110(A) and (B).

  1. Single-Family Residential Design Standards for all projects.1, 2
    1. There shall not be a three-car wide driveway curb cut.
    2. No more than fifty percent of the front elevation of a house shall consist of garage area, unless doing so would result in an area that could not accommodate the minimum required setbacks and enclosed parking area.
      1. The maximum width of a garage on the front elevation shall be twenty-five feet, which will accommodate a two-car garage. Additional garage spaces shall be provided through the use of a tandem garage or a detached accessory structure at the rear of the property.2
    3. Usable living area, not including any architectural feature, porch, or patio, shall be a minimum of two feet closer to the street than the garage, unless a side entering garage with curved driveway is provided or the lot is not wide enough to accommodate living area adjacent to the garage.
    4. All roofs shall have at least a one-foot overhang.
    5. Air conditioning units and similar mechanical equipment such as generators, sump pumps, heating, and ventilation equipment should be ground-mounted and screened from public view, or underground, and shall meet accessory structure setbacks and adhere to the requirements of Chapter 10.48 of the Municipal Code. Mechanical, heating, or cooling equipment or associated piping installed on the roof shall be screened from the public right away, except in R1‐e zones where roof top equipment is not allowed.
    6. Porches are encouraged.
      1. In the R1-a zone, the following porch design guidelines apply2:
        1. When viewed from the street, a porch shall appear proportionately greater in width than in height. A porch differs from an entry element, which has a proportionately greater height than its width.
        2. Structural supports shall be designed such that the appearance is not obtrusive or massive.
        3. The use of large columns or pillars is discouraged.
        4. The eave height for a front porch shall not be significantly taller than the eave height of typical single-story elements in the neighborhood.
        5. Porch elements shall have detailing that emphasizes the base and caps for posts and fence elements.
      2. In R1-6e and R1-a zones, entry features shall not be higher than fourteen feet from natural grade to plate.2
    7. All garage doors shall be recessed a minimum of six (6) inches from the surrounding building wall and shall include trim of at least one and a half (1.5) inches in depth.
    8. Where the garage faces the side yard, but is visible from the street, the garage shall incorporate a window on the street front facade so that it appears to be a habitable portion of the house. The window style must be the same as the windows on the habitable dwelling unit(s).
    9. Exterior and/or uncovered stair access shall not be allowed to the second floor.
    10. Except in R1-e zones, the elevation facing a street shall incorporate at least four architectural features, such as bay windows or an entry feature, and/or elements of architectural interest, such as wall insets or offsets, planters, railings, trellises, a combination of roofing elements (e.g., hip and gable roofs), dormers, change in architectural materials, quoins, accent tiles, or a prominent accent window inset greater than six inches. Windowsills, door or window trim, and roofing materials do not count as one of the features.
    11. Gable ends and Dutch gable ends taller than thirty inches shall include at least one element of architectural interest such as:
      • a wall offset with corbels, brackets, or change in materials;
      • louvered wood or metal vents;
      • clay of terracotta tile vents;
      • accent tile decoration;
      • medallion decoration;
      • metal grille;
      • a change in architectural materials;
      • incorporation of corbels;
      • decorative gable pediments;
      • eyebrow trellises or pergola structurally attached to the building; or
      • windows/glazing.
    12. Stone veneer or accent materials used as a wainscot on a street facing façade shall be wrapped around to the side façade and end at a logical terminus, such as a fence line or a chimney or at an interior corner. Stone veneer or any other siding material wrapped on columns shall terminate at the floor or ground, as applicable.
  2. Two-Story Design Guidelines.1, 2
    1. The mass and bulk of the design should be reasonably compatible with the predominant neighborhood pattern. New construction should not be disproportionately larger than, or out of scale with, the neighborhood pattern in terms of building forms, roof pitches, eave heights, ridge heights, and entry feature heights.
    2. The design should use vaulted ceilings rather than high exterior walls to achieve higher volume interior spaces.
    3. Long, unarticulated, exposed second story walls should be avoided since it can increase the apparent mass of the second story.
      1. In the R1-a zone, all second story wall heights greater than six feet, as measured from the second story finished floor, should have building wall offsets at least every twenty-four feet, with a minimum four foot depth and ten foot width. The offsets should comprise the full height of the wall plane.2
    4. The current pattern of side setback and garage orientation in the neighborhood should be maintained.
    5. When possible, doors, windows and architectural elements should be aligned with one another vertically and horizontally and symmetrical in number, size and placement.
    6. In the R1-a zone, windows on the side elevations should2:
      1. Be fixed and obscured to a height of five feet above the second floor;
      2. Have permanent exterior louvers to a height of five feet above the second floor; or
      3. Have sill heights of five feet or greater to mitigate intrusion into a neighbor's privacy.
  3. Residential Design Review Principles. Two-story homes subject to design review per Section 19.28.040(E) (except in R1-a zones) shall meet the residential design review principles below. The City of Cupertino Two-Story Design Principles are attached hereto as Appendix A and are incorporated herein by this reference.
    1. An identifiable architectural style shall be provided;
    2. Design features, proportions and details shall be consistent with the architectural style selected;
    3. Visual relief deemed to be appropriate by the Director of Community Development shall be provided;
    4. Materials shall be of high quality;
    5. Ensure building mass and scale;
    6. Design with architectural integrity on all sides of the structure; and
    7. The design shall reflect symmetry, proportion and balance.

Notes:

1 Refer to the Eichler Design Handbook- Fairgrove Neighborhood for additional design guidelines in the R1-6e zone.

2 Nonconformance with the design guidelines in the R1-a zone shall be considered acceptable only if the applicant shows that there are no adverse impacts from the proposed project.

      1. The tree shall be twenty-four-inch box or larger low to moderate water using tree that typically grows to a mature height of more than 30 feet, planted at a minimum height of six feet, as measured from adjacent grade. California native trees are preferred.
      2. The tree shall be planted in front of new second stories in the center 50% of the front yard setback area.
        1. In the R1-a zone, the tree shall be placed to where views from second story windows across the street are partially mitigated.
      3. The Director of Community Development may waive the front yard tree or allow the tree to be planted outside of the center 50% of the front yard setback area based on a report from an internationally-certified arborist citing unavoidable conflict with existing mature tree canopies onsite or in the public right-of-way.
      4. An existing mature tree in the front yard that is or can typically grow to a height of 30 feet or more and is located in the center 50% of the front yard can be used as the front yard tree, subject to an ISA certified arborist certifying that the tree is in good health.
      5. A covenant shall be recorded to identify the front yard tree as a Protected Tree and notifying current and future property owners to retain and maintain the tree in good health.
