The Architectural Styles for new development apply to all new construction pursuant to this Division, except those areas within the boundary of an existing Specific Plan. The Architectural Styles Objective Design Standards identifies six (6) preferred architectural styles, as indicated below. Architectural design elements and materials shall be consistent throughout the project, recognizing that a building is three-dimensional and must be well-designed on all sides. Detailing, choice of materials, and window and door choices shall reinforce the overall project design. Alternative styles may be submitted to review by the Community and Economic Development Department, although discretionary approval may be required by the Planning Commission or Zoning Administrator.
A. 
Spanish Colonial Revival. The Spanish Colonial Revival architectural style draws inspiration from Spanish, Mediterranean, and early Californian influences, and it originated during the late 19th and early 20th centuries. Typically, buildings with this style exhibit an asymmetrical design. They are characterized by low-pitched roofs with minimal or no overhang, adorned with serpentine roof tiles. This style often incorporates wood framing and is covered with light-colored stucco siding. The use of arches is prevalent, particularly above doors, porch entries, and main windows.
B. 
Craftsman. The Craftsman architectural style originated in the early 20th century as part of the Arts and Crafts movement. Notable design features include exposed rafters and beams beneath the eaves, decorative brackets and fasteners, full or partial-width porches, and prominent columns or piers. While the Craftsman style emphasizes a horizontal emphasis, vertical architectural elements are often incorporated to highlight corners and entrances. Traditional Craftsman homes typically showcased exterior cladding made of wood shingles or clapboard siding, along with details such as extended lintels and decorative lighting with geometric patterns.
C. 
Farmhouse. The Farmhouse architectural style is an expression of rural residential designs and materials, with the Contemporary Farmhouse style specifically reflecting the agricultural history and commercial structures found in Southern California. This style incorporates playful elements, such as shed roofs, vibrant color blocking, and contemporary interpretations of traditional farm structures like barns and silos. The roofs of Farmhouse-style buildings are typically medium to high-pitched, and the overall detailing is kept simple.
D. 
Tuscan. The Tuscan architectural style blends modern and classic elements, incorporating both Spanish Revival and Italian influences. This style draws inspiration from Mediterranean variants found in California, showcasing rustic elements. Key characteristics include the use of stone and stucco, light earthy tones, and red tiled roofs. Classical elements like columns, arches, and decorative ironwork add visual interest and complexity. Squared towers and projections reflect classic Italianate influences. Porches and porticoes are commonly featured, as well as vertically oriented recessed windows.
E. 
Modern. The Modern architectural style draws inspiration from utilitarian design principles, featuring block forms, contrasting colors, and eclectic combinations of materials in contemporary compositions. This style embodies a minimalist and clean aesthetic. It utilizes simple rectangular shapes and forms, integrating them within horizontal and vertical planes to create dynamic lines. Flat roofs are commonly used to reinforce the rectangular shapes while also providing opportunities for outdoor deck areas. Accents in the Modern style are understated and unpretentious, often taking the form of trellis elements.
F. 
American Traditional. The American Traditional architectural style is a fusion of various traditional American styles such as Cottage, Cape Cod, and Farmhouse. It is characterized by simplicity and classic design elements, including rectangular forms, spacious front porches, decorative shutters, dormers, and wood siding. This style represents a traditional interpretation of rural farmhouses. The color palette used in American Traditional homes is typically subtle, with shades of white or gray for the main body of the house, while light or dark shutters provide contrasting accents.
