Lower Density Residential Objective Design Standards
1 INTRODUCTION
This document includes objective design standards for specified lower density residential development, as described in Section 1.1 of this document.
These standards were adopted in response to legislation passed by the State of California that applies to housing projects defined in Government Code Section 65589.5. These standards are consistent with Government Code Sections 65913.4 and 66300(a)(7) in that they do not “involve personal or subjective judgment by a public official and are uniformly verifiable by reference to an external and uniform benchmark or criterion available and knowable by both the development applicant and the public official prior to submittal.”
1.1 APPLICABILITY
The objective design standards are supplementary but subordinate to the zoning regulations applicable to the parcel on which each dwelling unit is located. Refer to the Sunnyvale Municipal Code (SMC) for definitions and to determine when a planning permit is required.
Lower Density Residential includes lots with single-family dwelling, two-family dwellings, and Dual Urban Opportunity (DUO) dwellings.
NOTE: These standards do not apply to dwellings subject to the Eichler Design Guidelines or Taaffe-Frances Heritage Neighborhood Design Guidelines. Lower density residential development projects in those neighborhoods shall be consistent with their respective guidelines. These standards also do not apply to changes to heritage resources and properties within a heritage resource district, which must comply with the Secretary of the Interior's Standards for the Rehabilitation of Historic Properties.
In addition to a building permit, a separate planning permit is required for certain types of residential projects, as outlined in Sunnyvale Municipal Code (SMC) Chapter 19.80. All lots with lower density residential units are also subject to 2.1.10. (Lighting standards).
Projects involving like-for-like replacements are exempt from compliance with the design standards. Regardless of whether a separate planning permit is required, the design standards within this document apply to the following projects:

Lower Density Residential Objective Design Standards
Refer to TABLE B.2 LOWER DENSITY RESIDENTIAL DESIGN STANDARDS APPLICABILITY, Appendix B for applicability of individual design standards.
1.2 EXCEPTIONS TO THE LOWER DENSITY RESIDENTIAL DESIGN
STANDARDS
Objective standards may be rigid by design and may not always result in high quality architecture. To introduce flexibility, many of the objective design standards allow for alternative compliance measures. Additionally, exceptions to objective design standards are provided to accommodate site-specific design situations.
Allowable exceptions from certain design standards include:
• New dwellings, including projects that qualify as a major remodel per the City’s Major Residential Remodels/New Construction policy.
• Any additions resulting in new gross floor area to existing dwellings. • New, expanded, or modified garages and carports.
• Increases in exterior wall plate heights.
• Exterior modifications to the second floor (including new, expanded, and relocated second floor windows and material modifications).
• New and expanded second-story balconies.
• Exterior modifications to the front and reducible front elevations, including:
o New or modified entry porches and doors
o Increase in roof pitches
o New roof spans, including those visible from the front and reducible front elevations
o Changes to roof form types (e.g. changing a hip roof to a gable roof) o Changes to exterior materials and colors
o New or modified entry walkways in the front and reducible front yard • Changes in roof material
• Site modifications including installation of:
o Artificial turf
o Pavers
o New and modified exterior lighting

Lower Density Residential Objective Design Standards
Number of Exceptions Permitted:
Identifying Exceptions:
• Exceptions do not eliminate the design standard itself but allow for a deviation of up to 25% from the specific dimensional requirements. For example, a required window recess of 2 inches may be reduced to 1.5 inches.
• Exceptions allowing a deviation of up to 25% from specific dimensional requirements only apply to numerical design standards and are not applicable to non-numerical design standards. For example, an exception is not possible for a design standard that establishes prohibited wall materials, such as no vinyl or plastic siding, because the standard is non-numerical. The list of numerical design standards that allow for such exceptions is provided in Applicability Table in Appendix B. • Projects subject to staff-level review are granted up to three exceptions. Projects requiring Planning Commission review are granted up to five exceptions. Exceptions within the allowable amount are allowed by-right and not subject to discretionary review.
• Applicants must identify which and how many exceptions are proposed in the design standards compliance checklist.

1.3 DESIGN PRINCIPLES
The objective design standards in Chapter 2 provide an objective framework for evaluating lower density residential development projects. These standards ensure alignment with the following design principles identified in this section:
The above design principles only serve to describe the intent behind the objective design standards in Chapter 2 and do not specifically apply to individual development projects.
1.4 ORGANIZATION
To enhance usability, this document is organized into different sections as described below:
• Neighborhood Scale and Pattern: Ensure compatibility with the neighborhood’s scale and development pattern. Street presence, scale, and mass are emphasized so that the proposed project fits/blends with the existing neighborhood. The neighborhood scale and pattern compatibility is addressed through overall building heights, arrangement of entries, and overall visual character as viewed from the street or public realm.
• Architectural Details and Materials: Use architectural details and materials that align with the proposed architectural style and require minimal maintenance to remain attractive over time.
• Privacy Consideration: Minimize privacy impacts on adjoining neighbors. • Minimize View of Parking: Reduce visual impact of parking areas and garages. • Water-Efficient Landscaping: Promote water-efficient landscaping practices and preserve mature trees whenever feasible.
• INTRODUCTION: Overview of the applicability and intent of the design standards. • DESIGN STANDARDS: Standards applicable to site layout, building placement, scale, mass, articulation, and materials etc. to guide applicable new lower density residential development.
• GLOSSARY: Narrative and graphic explanations of terms used throughout this document.

3.1 DEFINITIONS
Additional Architectural Style: An architectural style that is not included in Appendix A.
Balcony: An elevated platform designed for outdoor living purposes that is accessed from one residential unit.
Balustrade: A railing supported by balusters (one of a series of vertical elements supporting a handrail cap on a porch or balcony railing).
Bay Window: A window or windows in a wall that projects from the wall at an angle, with or without a foundation.
Board and Batten Siding: Wood wall siding with a vertical wood strip (batten) placed over the seams of larger vertical siding boards.
Carport: Covered structure with open sides, supported by posts, which provides shelter for single or multiple cars for the dwelling units on site.
Casement Windows: A casement window is hinged at the side and opens outward or inward along a vertical axis, typically operated by a crank, lever, or push mechanism.
Clerestory Windows: A clerestory window is a window located in the upper portion of a wall, typically above eye level for the purpose of bringing natural light into an interior space.
Cool Roofs: A cool roof is a roofing system designed to reflect more sunlight and absorb less heat than standard roofing materials, thereby reducing heat transfer into the building. For roofs less than or equal to 3:12 in pitch, a cool roof is a roofing system with a Solar Reflectance Index (SRI) greater than or equal to 82. For roofs greater than 3:12 in pitch, a cool roof is a roofing system with an SRI greater than or equal to 39. (USGBC Heat Island Reduction Criteria)
Cottage Windows: A cottage window is a double-hung window where the upper sash is visibly shorter than the lower sash.
Cornice: A projection at the top of a building wall near a roof or ceiling, intended to protect the wall or as ornamentation.
Courtyard: Outdoor area that is primarily open to the sky and surrounded by buildings, walls, or a combination of the two.

Covered Parking: Fully or partially enclosed parking areas, such as garages or carports, with a roof that is more than 50% solid.
Decorative: An element, design or motif, other than an architectural feature; installed, attached, painted or applied to the exterior of a building or structure for the purpose of ornamentation or artistic expression.
Decorative Band: A decorative band is a horizontal architectural element applied to a building elevation that provides visual interest, articulation, or stylistic emphasis.
Decorative Transom: A decorative transom is a horizontal window or panel located directly above a door or window, primarily for aesthetic enhancement or to provide visual interest.
Dimensional Roof Material: A dimensional roof material is a roof product which has a minimum thickness of 1/4 inch, simulating the appearance of traditional materials such as wood shakes, slate, or tile.
Direct Illumination: Direct illumination refers to unobstructed light that reaches a surface or space without reflection or diffusion, either from sunlight or a powered light fixture or lamp.
Dormer: A window projecting from the slope of a roof, usually with a roof of its own.
Double Hung Window: A double hung window is an operable window type with two vertically stacked sashes that may slide independently, upward or downward, within the frame.
Eave: The portion of a roof that projects beyond the wall, often supported by rafters or serving as support for gutters.
Front Elevation Length: The length of the front elevation is the cumulative width of all front- facing walls, projections, and recesses that are visible from a straight-on view of the front elevation.
Front Elevation Area: The area of the front elevation is the cumulative surface area of all front-facing walls, projections, and recesses that are visible from a straight-on view of the front elevation. It excludes area of doors and windows.
Front Elevation: The front elevation of each dwelling unit is the façade that faces the street.
For corner lots, the front elevation shall be the façade along the narrower frontage that runs parallel to the street.

Garage: A garage is a structure built for the storage of vehicles which is fully enclosed on all sides.
Header Trims: A header trim is a decorative piece of trim installed above windows, doors or an opening. It serves both functional and aesthetic purposes, by enhancing the architectural character while also covering any gaps or seams between the wall and the frame.
Hip Roof: A hip roof is a type of roof design where all sides slope downward towards the walls, usually with a gentle slope. Unlike a gable roof, which has two sloping sides and vertical ends, a hip roof has four sloping sides that meet at a peak or a ridge.
Integrated Masonry Planters: An integrated masonry planter is a permanent, built-in planting container constructed of brick, stone, concrete, or other unit masonry materials, which is structurally and visually incorporated into the architectural design of a building, wall, or landscape feature, and not movable or freestanding.
Intersecting Hip or Gable Roofs: An intersecting hip or gable roof is a complex and highly articulated roof design where two or more roof sections intersect and overlap. This creates multiple planes that meet at different angles, reducing mass and scale while bringing visual interest to the roof.

Plate Height: Plate height is measured from the top of the finished floor to the top of the wall plate (shown in blue and red, respectively, in FIGURE 3.3). Both typical and flat roof examples are provided. For shed roofs with variable plate height, refer to FIGURE 2.3. Wall Plate is a horizontal member (e.g., lumbar, brace, etc.), built into or laid along the top of a wall, that supports framing members. Second floor plate heights shall be measured from second floor finished floor, except when it encloses a void (such as double height space).

Porch: An entry porch is a roofed, unenclosed, or partially enclosed exterior space attached to the front elevation of a dwelling unit. It is physically defined by a dedicated finished floor plane distinct from adjacent grade and extending beyond adjacent wall planes, and most incorporate a building entry.
Predominantly One-story Neighborhood: A predominantly one-story neighborhood is defined as an area where fewer than 20% of the homes are two-story structures.
Rafters: Rafters are inclined structural beams that form the framework of a roof, supporting the roof covering material while helping distribute the weight evenly across the structure. They extend from the ridge to the eaves of the roof.
FIGURE 3.4: Rafter Definition
Ribbon Windows: A horizontal series of three windows or more set side by side, separated only by mullions, that form a continuous horizontal band across the façade of a home.
