(H) Design standards for Townhome and Multiple-Family Structures.
(1) Design requirements: row style, multi-story (not stacked) or 1 level attached.
(2) Design character. A high quality of building design is an important way to bring larger buildings into a traditional neighborhood scale. In addition, site design, landscaping, and pedestrian amenities will help to create a comfortable, livable district and a shared sense of ownership among residents.
(a) Subdivision requests. Building elevations and floor plans shall be furnished with subdivision requests illustrating exterior building material and colors to demonstrate compliance with this section. Building floor plans shall identify the interior storage space within each unit.
(b) Decks or porches. Provision shall be made for possible decks, porches, or additions as part of the initial dwelling unit building plans. The unit lot shall be configured and sized to include decks or porches.
(c) Minimum overhang. In case of a gable roof, a minimum 12 inch soffit shall be required.
(d) Exterior building finish. The exterior of attached/townhome dwelling units shall include a variation in building materials which are to be distributed throughout the building facades and coordinated into the architectural design of the structure to create an architecturally balanced appearance. In addition, attached/townhome dwelling structures shall comply with the following requirements:
1. A minimum of 25% of the combined area of all building facades of a structure shall have an exterior finish of brick, stucco, and/or natural or artificial stone.
2. Except for brick, stucco, and/or natural or artificial stone, no single building facade shall have more than 75% of 1 type of exterior finish.

(3) Building design and materials, multi-family (stacked).
(a) Design character: The scale of multi-family dwellings makes the buildings highly visible and it is critical to incorporate high quality architecture. All buildings shall be designed to accomplish the goals and policies of the Comprehensive Plan. Building materials shall be attractive in appearance, durable, and of a quality which is both compatible with adjacent structures and consistent with the city’s standards for the district in which it is located. All buildings shall be of good aesthetic and architectural quality, as demonstrated by the inclusion of elements such as accent materials, entrance and window treatments, contrasting colors, irregular building shapes and rooflines, or other architectural features in the overall architectural concept.

Panel seam lines shall be architecturally integrated into the building design so that they are not visible. Seam lines can either be filled, covered with accent material or some other method to make seam lines invisible. Accenting materials and design shall be included on all facades.
(d) All building and roofing materials shall meet current accepted industry standards and tolerances, and shall be subject to review and approval by the city for quality, durability, and aesthetic appeal. The applicant shall submit to the city product samples, color building elevations, and associated drawings which illustrate the construction techniques to be used in the installation of such materials.
(e) If complementary building styles, materials, and color schemes are proposed for a development, the developer shall submit to the city a plan showing the distribution of the styles, materials, and colors throughout the development.
