A. 
The MU (Mixed Use) Districts have been established to encourage the development and redevelopment of specific areas of the City into quality, dynamic, pedestrian-oriented environments by permitting a combination of commercial, office, service, entertainment, and residential uses within these areas. In MU Districts, new development shall emphasize the interface between uses and pedestrian connections in addition to site aesthetics and amenities. All development shall be constructed in a manner that provides interaction between adjacent uses whether the uses are part of the same development or are located in adjacent development within the same district. The landscaping, placement of street furniture, lighting, and similar amenities shall be such that it will enhance the pedestrian quality of the mixed-use development. Building design should provide for "informal" surveillance of shared areas by residents, business tenants, and users of the development. The types and mix of uses, the intensity of development, and the residential density permitted in the MU Districts vary by individual mixed use district.
B. 
The intent of the MU Districts is to provide for a combination of land uses within the boundaries of the districts, not necessarily a combination of uses on individual lots. A combination of uses may not be feasible or appropriate on an individual lot based upon the unique characteristics of the lot, including the lot's size, shape and location, existing development on the lot, and/or the lot's surrounding uses and development.
C. 
Within a MU District, the integration of different categories of land uses may involve complementary uses on different floors of a building or within a complex, or complementary uses located side by side along a City block on the same lot or separate legal lots.
D. 
This chapter applies to all land in the MU Districts. Any and every building, premises, and land in the MU Districts shall be used for or occupied, and every building shall be erected, constructed, established, altered, enlarged, maintained, moved into, or within the MU Districts only in accordance with all applicable sections of this chapter, and regulations of this Code.
(08-05)
The Mixed Use (MU) Districts are as follows:
A. 
MU1 (Indian Hill/Arrow Highway Mixed Use District). The MU1 District is located southeast of Indian Hill Boulevard and Arrow Highway. Emphasis is on retail uses on the ground floor along Indian Hill Boulevard and Arrow Highway frontages, with residential/offices on the upper floor. Residential uses are encouraged, and retail commercial uses need not be included adjacent to the adjoining single-family neighborhood. Commercial development has a maximum floor area ratio (FAR) of 1.3. Residential development has a maximum density of 22 units to the acre.
B. 
MU2 (College Avenue/South Village Transit-Oriented Mixed Use District). The MU2 District is located south and east of the Claremont Transit Center. Development in this district should be a positive addition to the Claremont Village environment and be designed to encourage use of alternative modes of transportation. A mix of uses are encouraged with an emphasis on residential uses with limited office/commercial possible along College Avenue and First Street, and other ground floor areas. Development on individual lots need not include both commercial and residential uses, but shall complement uses on surrounding properties. Commercial development has a maximum floor area ratio (FAR) of 1.5. Residential development has a maximum density of 22 units to the acre.
C. 
MU3 (W. Foothill Boulevard Mixed Use District). The MU3 District includes properties that front on Foothill Boulevard and back up to single-family residential development. Mixed uses will include an emphasis on ground floor retail along Foothill Boulevard with residential uses permitted on upper floors and/or as a transition to adjacent single-family residential development. Commercial development has a maximum floor area ratio (FAR) of 1.5. Residential development has a maximum density of 15 units to the acre.
D. 
MU4 (Base Line Road Corridor Mixed Use District). The MU4 District is located southeast of Towne Avenue and Base Line Road, north of the 210 Freeway. Uses shall include a retail commercial component along the Towne Avenue frontage to serve freeway travelers and adjacent neighborhoods. Residential and office uses may be included on upper floors and/or adjacent to the commercial uses. Commercial development has a maximum floor area ratio (FAR) of 1.5. Residential development has a maximum density of 15 units to the acre.
(08-05)
A. 
The only uses and development permitted in MU Districts are those uses specified as permitted uses in the MU Districts pursuant to Table 16.051.A, or as otherwise specifically permitted elsewhere in this title.
B. 
All uses noted in Table 16.051.A as permitted with a "CUP" require approval of a conditional use permit, pursuant to Chapter 16.303. Uses permitted with a "SUDP" require approval of special use and development, pursuant to Chapter 16.306.
C. 
A use that is not permitted, permitted as a conditional use (CUP), or permitted with a special use and development permit (SUDP) is prohibited unless the Director of Community Development determines that such use is the same as, or similar to, a permitted use, conditional use, or special use pursuant to Chapter 16.339.
D. 
Multiple-family development is permitted at a maximum density of 22 dwelling units per acre in the MU1 and MU2 Districts, and a maximum density of 15 units per acre in the MU3 and MU4 Districts. Areas devoted to commercial uses shall be included in determining residential densities. Allowable densities in all Mixed Use Districts may be increased through the provision of affordable housing in accordance with applicable state and federal laws.
E. 
Live-work units are permitted in MU Districts subject to the regulations of this chapter, and if located in a commercial structure, live-work units shall not be included in determining the residential density of a project.
F. 
The provisions of Chapter 16.051 related to outside uses, manufacturing, fabrication or wholesaling of goods, sale of alcohol beverages, auto service centers, and drive-through facilities shall be applicable to all MU Districts, unless otherwise specified by this title.
(08-05; 10-03)
A live/work unit means a residential dwelling unit where there is one or more rooms containing working space located within, adjacent to, or near the residential unit, and one or more individuals living in the residential unit regularly use the working space to earn their livelihood, usually in professional or design-related activities.
(08-05)
All new development shall be designed and developed to promote the integration of uses and development within the Mixed Use Districts, and, if feasible, to share access and parking with adjacent development. Property owners shall be encouraged to consolidate properties and/or to work together to create unified development complexes.
(08-05)
The minimum lot size in the Mixed Use Districts is one acre, except lots of less than one acre may be created as pads for buildings that are part of a larger complex in which parking and access is shared.
(08-05)
The development standards in Table 16.040.2 shall apply to all Mixed Use (MU) Districts.
TABLE 16.040.2
Number of stories and building height
MU1 and MU2: maximum three stories or 42 feet
MU3 and MU4: maximum two stories or 28 feet
Building placement
Developers are encouraged to place buildings forward on properties towards the public street(s), and structures may occupy the entire width of a property, excepting that a minimum building setback of 10 feet is required along a street frontage and any residential district. Any third story facing an interior lot line that is a boundary of a single-family residential district shall have an additional 10-foot setback. There are no other required setbacks from lot lines.
FAR/density
See MU District characteristics above. Calculations of FAR shall not include underground parking.
Usable open space
150 sq. ft. per residential unit for 5 or fewer units, 120 sq. ft. per unit for more than 5 units. Usable open space may be any combination of private and common open space, and may include, but is not limited to, private patios and balconies, shared use plazas and courtyards, and/or shared recreation areas. Usable open space shall have a minimum dimension of 6 feet for private open space, and a minimum dimension of 15 feet for common open space. Internal walkways and pathways connecting such open areas and amenities shall not be included in calculations of open space for purposes of meeting the minimum usable open requirement.
Residential parking
One covered parking space is required for dwelling units 600 gross square feet or less. Dwelling units greater than 600 gross square feet require 2 covered parking spaces. In addition, 0.5 uncovered or covered parking spaces per dwelling unit are required for visitor parking. In mixed-use development, visitor parking may share the required parking provided for nonresidential uses.
Live/work parking requirements
In the MU1, MU3, and MU4 Districts: Required parking shall be the combined total of the following:
► One covered parking space per unit if the area designed or used for residential living is 600 square feet or less, or 2 covered parking spaces per unit if the area designed or used for residential living is greater than 600 square feet; plus
► One covered or uncovered visitor space per 350 square feet of building area designed or used as work/office space.
In the MU 2 District: Required parking shall be combined total of the following:
► One covered parking space per unit if the area designed or used for residential living is 600 square feet or less, or 1 covered space plus 0.5 uncovered parking space per unit if the area designed or used for residential living is greater than 600 square feet; plus
► One covered or uncovered visitor space per 500 square feet of building area designed or used as work/office space.
Non-residential parking
In MU1, MU3, and MU4 Districts: Retail, service and office uses require 1 parking space per 250 square feet of net floor area. Restaurant uses require 1 parking space per 100 square feet of net floor area of interior area of restaurant, and 1 parking space per 175 square feet of net floor area designated for outdoor dining in connection with a specific restaurant. For other uses, the parking requirements shall be as required for such uses in the CH District.
In MU2 District: Retail and service uses require 1 parking space per 500 square feet of net floor area. Office uses require 1 parking space per 350 square feet of net floor area. Restaurant uses require 1 parking space per 150 square feet of interior area of restaurant, and 1 space per 200 square feet of net floor area designated for outdoor dining in connection with a specific restaurant. For other uses, the parking requirements shall be as required for such uses in the CV District.
Parking for "micro-breweries in connection w/restaurant" in the MU1 District includes the individual parking requirements for areas used for the micro-brewery (beer manufacturing, storage and off-site distribution) at 1 space per 400 square feet of gross floor area as this light-manufacturing use has a lower parking demand than retail and food service uses. Restaurant, dining and outdoor dining areas of a business will be subject to the existing parking standards for restaurant uses.
Approval of reduced parking
The Architectural Commission may grant a reduction in the amount of required parking for a mixed-use project when it can be demonstrated that the parking demand from the different uses will vary during the day and/or week, and the parking demands for the uses can be jointly met by the reduced parking. Uses for which shared parking is approved must share parking facilities and driveways, and have interconnected pedestrian pathways. The Architectural Commission may also grant a reduction for available street parking or when an applicant can demonstrate that there are special characteristics of the development that will result in less parking demand than the required parking. One such special characteristic could be that the project is designed and located as transit oriented development. If parking for a use is located on a lot other than the lot where the use is located, there shall be an agreement for shared parking facilities and driveways by legal instrument, to which the City is a party.
Signs
In MU1 District, signs are subject to the sign regulations applicable to the CL (Commercial Limited) District.
In MU2 District, signs are subject to the sign regulations applicable to the CV (Claremont Village) District.
In MU3 and MU4 Districts, signs are subject to the sign regulations applicable to the CH (Commercial Highway) District.

A. 
In order to provide that new development in the MU Districts is compatible with adjacent uses and meets the goals of the General Plan and the intent of the MU Districts, the Director of Community Development shall review all proposed development projects in the MU Districts to determine if Planning Commission review of the projects is required. A proposed development project in the MU Districts shall require review by the Planning Commission prior to project approval if the Director finds that the proposed development project would result in any of the following conditions:
1. 
A new development consisting of a combination of commercial and residential uses.
2. 
A new residential use within an existing commercial center or grouping of commercial uses that share parking or driveway access from a public street.
3. 
A new residential use that abuts an existing commercial use.
4. 
A new commercial use within an existing residential development or that would abut an existing residential development within a MU District.
B. 
In addition, the Director may refer to the Planning Commission for review any proposed development project in the MU Districts where the Director determines there is a land use issue that may not be consistent with the intent of the MU Districts and/or could result in development inconsistent with other uses in the surrounding area.
C. 
In reviewing a proposed project, the Planning Commission shall make a finding of whether the project meets the following criteria:
1. 
The project and the proposed uses are consistent with characteristics of the district and the planned uses for the district as set forth in the General Plan and this chapter.
2. 
The proposed project provides for the efficient development of a site, and demonstrates an understanding of the site's unique characteristics.
3. 
The project includes a commercial component, if feasible and appropriate given the district characteristics as set forth in the General Plan and this chapter, and the site's unique characteristics, including the property's size, shape and location, existing development on the site, and surrounding uses and development.
4. 
The planned uses in the project are compatible with and complementary to existing and/or planned uses in surrounding areas, and are designed in a manner that will minimize potential impacts of noise, glare, privacy, and safety to adjacent properties.
5. 
The project emphasizes a pedestrian-oriented environment and encourages interaction between existing and/or planned adjacent development to the extent feasible considering the characteristics of the site and the surrounding development.
6. 
The project will enhance the mixed-use district in which it is located, and shall promote the City's goals and policies as stated in the General Plan.
D. 
The Planning Commission shall report its finding on the above criteria prior to the architectural review of the project.
E. 
All proposed projects in the MU Districts shall be subject to Section 16.040.080 pertaining to design guidelines for mixed-use development and the architectural review criteria in Chapter 16.300.
(12-01)
The design guidelines in Table 16.040.3 shall be considered in the review of new mixed-use development projects. While the guidelines are not absolute requirements, proposed mixed-use projects should adhere to each of the guidelines unless it is determined by the review body that a guideline is not feasible and/or appropriate for a specific project. In addition, prior to approval of any new development project in the MU Districts, the required architectural review findings shall be made by the review body pursuant to Chapter 16.300. The review body may include staff, Architectural Commission or City Council.
Table 16.040.3 Design Guidelines for Mixed Use Development
