The purpose of the Mixed-Use (MU) zoning district is to provide locations for developments that either combine commercial or retail uses with multi-family residential uses in a building, or provide mixed-uses in separate buildings within close proximity to other uses along a corridor or within a walkable district. By allowing a mix of uses, residential uses can be located within close proximity to jobs, shopping, and entertainment opportunities to increase pedestrian activity and neighborhood vitality.

1. General requirements. The following design standards shall be required of all development in the mixed-use zoning district in order to create a cohesive appearance that is pedestrian friendly and which encourages travel by public transportation, bicycling, van pooling, and car pooling.
2. Wherever practical, buildings shall incorporate arcades, roofs, alcoves, porticos, and awnings that protect pedestrians from the rain and sun.
3. Trash storage areas, mechanical equipment, transformers, air conditioning units, meters, and similar devices are not permitted to be visible from the street, or to be located on patios/balconies associated with a residential unit. Where site constraints would otherwise force these uses into visible locations, they shall be screened by decorative walls, earthen berms, landscaping, or architectural treatments capable of screening views from streets and sidewalks. If in rooftop locations, mechanical equipment shall be screened by roof components, parapets, cornices, or other architectural features.
4. All uses located in the zoning district shall be conducted entirely within a fully enclosed building. There shall be no outside storage of materials or equipment, other than motor vehicles licensed for street use except as specifically approved by the Land Use Authority in conjunction with a conditional use application.

Buildings that are open to the public and are within 30' of the street shall have an entrance for pedestrians from the street to the building interior. This entrance shall be designed to be attractive and functional, be a distinctive and prominent element of the architectural design, and shall be open to the public during all business hours.
6. Buildings shall incorporate exterior lighting and changes in mass, surface, or finish to give emphasis to entrances.
7. Buildings shall provide a clear visual division between all floors. The top floor of any building shall contain a distinctive finish, consisting of a roof, cornice, or other architectural termination.

Compliance can be achieved through balconies, alcoves, or wall segments that create at least a two foot variation in plane for at least ten lineal feet within each 30' segment of façade.
9. In paseos, plazas, and courtyards, lighting shall incorporate fixtures and standards designed for pedestrian areas.
10. All new utility transmission lines shall be placed underground.
11. At least 75% of the lineal frontage of any ground floor, non-residential wall with street frontage shall incorporate windows, doors, or display windows.

Non-residential uses on the first floor shall have walls, partitions, and floor/ceiling assemblies separating dwelling units from other spaces. When operated, any equipment, machines and instruments shall not emit a noise level greater than 85 decibels (dB), and shall not emit detectable vibration, dust, odor, fumes or gas beyond the boundary of the property or noise above ambient level (size limit). Interior noise levels associated with business operations and machines may be increased above 85 dB if interior building sound attenuation is applied to mitigate any sound increase that would otherwise transmit into attached commercial or residential units.
13. For development sites greater than 20,000 square feet, primary uses shall be incorporated into a project where at least 80% of the floor plate area of new buildings is constructed at a minimum of two stories in height.
14. No drive-through shall be allowed between the building and the public street right-of-way.
15. All truck loading and pick-up shall be provided at the rear, or side of a building. Pick-up and deliveries are limited between the hours of 7:00 a.m. and 10:00 p.m. for all non-residential uses except for restaurant, fast food eating establishment, and grocery retail.

Utilities shall not be placed in the patio/balcony areas.
20. Ground floor residential units adjacent to a sidewalk shall incorporate a primary entrance to each residential unit including a walkway connecting the residential unit to the sidewalk.
21. To preclude large expanses of uninterrupted building surfaces, exterior elevations shall incorporate design features such as offsets, balconies, projections, or similar elements along each face of the building facing and visibly parallel to a public right-of-way or public plaza. Along the vertical face of the structure, offsets shall occur at a minimum of every 30 linear feet by providing any two of the following:
22. recesses (elevated decks, patios, entrances, etc.) with a minimum depth of four feet, or
23. extensions (elevated decks, patios, entrances, floor area, etc.) with a minimum depth of four feet, or
