18.22.010 Specific purposes – Summary of mixed-use districts.

A. Specific purposes. In addition to the general purposes listed in PHMC § 18.05.020, the specific purposes of mixed-use districts are to:

1. Ensure mixed-use development is consistent with the overall community character and serves the existing and future needs of residents and visitors.

2. Allow a variety of compatible land uses that provide flexibility to property and/or business owners.

3. Achieve compatibility between new mixed-use development and surrounding less intensive residential and commercial uses by establishing physical development standards and performance standards.

4. Ensure adequate development standards and regulations are in place to foster successful and innovative mixed-use developments.

B. Summary of mixed-use districts. Four mixed-use districts are established to carry out these purposes:

1. MX-NB mixed-use neighborhood districts. The MX-NB district allows a range of neighborhood-serving commercial uses (e.g., coffee shops, grocery stores, retail establishments). It is the intent of this zone to provide a mix of compact single-family, multiple-family residential, and commercial uses located within the same building (vertical mixed-use) or on the same site (horizontal mixed-use). A variety of residential typologies are encouraged in the form of compact single-family in horizontal format, townhouses, condominiums, or apartments at a density between one and 20 units per acre.

2. MX mixed-use districts. The MX district allows for the most intensive uses, including high-density residential, commercial, hotels, office, entertainment, and personal services, located within the same building (vertical mixed-use) or on the same site (horizontal mixed-use). A variety of residential typologies are encouraged in the form of multiple-family residential uses including live-work units, townhouses, apartments, studio flats, and condominiums at a density between 12 and 40 units per acre.

3. MX-HD mixed-use high-density districts. The MX-HD district allows for diverse uses, including residential, commercial, office, entertainment, and personal services, located within the same building (vertical mixed-use) or on the same site (horizontal mixed-use). Multiple-family residential uses include live-work units, townhouses, apartments, studio flats, and condominiums at a density between 40 and 70 units per acre.

4. MX-VHD mixed-use very high-density district. The MX-VHD district allows for the most intensive uses, including high-density residential, commercial, hotels, office, entertainment, and personal services, located within the same building (vertical mixed-use) or on the same site (horizontal mixed-use). A variety of residential typologies are encouraged in the form of multiple-family residential uses including live-work units, townhouses, apartments, studio flats, and condominiums at a density between 70 and 100 units per acre. (Ord. 967 § 7, 2024)

18.22.020 Land use regulations for all mixed-use districts.

In Schedule 18.22.020, the uses allowed for each mixed-use zoning district are established by letter designations as follows:

“P” designates use classifications permitted in mixed-use districts.

“U” designates use classifications permitted on approval of a use permit.

“T” designates use classifications permitted on approval of a temporary use permit.

“L” followed by a number designates use classifications subject to certain limitations listed by number following the schedule.

“P/U” designates use classifications permitted on the site of a permitted use, but requiring a use permit on the site of a conditional use.

The uses listed are based on the use classifications set forth in PHMC Chapter 18.15. Use classifications not listed are prohibited unless authorized by zoning administrator resolution under PHMC § 18.15.010. The “Additional Use Regulations” column includes specific limitations applicable to the use classification or refers to regulations located elsewhere in this title.

18.22.040 Additional development regulations corresponding to Schedule 18.25.030.

A. Commercial uses. Mixed-use sites not identified as a housing opportunity site towards part of the RHNA in the Pleasant Hill Sixth Cycle Housing Element (2023-2031) shall include a minimum percentage of commercial based on the total proposed square footage of the project. Table 18.22.040-1 outlines the minimum percentage of commercial based on specific corridors within the city.

 

Table 18.22.040-1
Mixed-Use Zone Setback Encroachments 

25% COMMERCIAL REQUIREMENT (OF TOTAL GROSS FLOOR AREA)	15% COMMERCIAL REQUIREMENT (OF TOTAL GROSS FLOOR AREA)	10% COMMERCIAL REQUIREMENT (OF TOTAL GROSS FLOOR AREA)
Contra Costa Boulevard	Gregory Lane	All remaining areas
Golf Club Drive	Oak Park Boulevard
Monument Boulevard	Pleasant Hill Road
Downtown	Ellinwood Way

B. Mixed-use commercial exception. Any existing single-family use in a mixed-use zone (MX-N, MX, MX-HD, MX-VHD), or the replacement of an existing single-family use, is exempt from compliance with the mixed-use requirements for percentage of commercial uses outline in Table 18.22.040-1 and is considered a conforming use, for as long as the existing single-family use continues on the site. This exemption does not apply to:

1. Sites designated as housing opportunity sites in the Pleasant Hill Sixth Cycle Housing Element (2023-2031).

2. Sites that undergo a lot merger with adjacent sites. Any parcels that undergo a lot consolidation shall adhere to all mixed-use use and development standard requirements.

C. Reductions from the commercial requirement. A use permit is required for mixed-use developments seeking to reduce the minimum commercial requirements in Table 18.22.040-1 and that are not exempt per subsection B of this section. Additionally, a market/retail feasibility study will be required justifying the proposed reduction in commercial and why the required commercial is not feasible or that the net realized benefit to the city will be comparable to the minimum commercial percentage requirement.

D. MX-N, MX, MX-HD, and MX-VHD districts adjoining single-family residential districts.

1. Planting area. A continuous planting area having at least a minimum width of five feet and at least five trees per 100 linear feet shall be provided along interior property lines adjoining a single-family residential district.

2. Fences and walls. A required yard abutting a residential district shall be enclosed by a solid wood, concrete, or masonry wall at least six feet but not more than eight feet in height, except that a wall within 15 feet of a street property line shall not exceed three feet in height. (See also PHMC § 18.25.140.)

REQUIRED WALLS: RESIDENTIAL USE ABUTTING NONRESIDENTIAL USE

(The diagram is illustrative)

E. Building height, required yards, and stepbacks. In addition to all applicable standards established in this chapter, buildings taller than 35 feet in height located on a parcel adjacent to a single-family residential zone shall use a minimum of one of the following techniques:

1. Stepbacks. The building shall be designed to “stepback” upper floors at least one foot for every one foot of increased building height above 35 feet. For example, consider a building with a proposed height of 40 feet. The height of the main wall of the building base would start at 35 feet at the required side and/or rear yard line, then increase by one foot for every foot beyond the side/rear yard line until it attains the height of 40 feet at a minimum distance of five feet behind the side/rear yard line.

2. Additional side and rear yard area. The required side and rear yards shall be increased by one foot for every one foot of structure height in excess of 35 feet, not to exceed 10 additional feet. For example, a building with a proposed height of 40 feet would have to be set back an additional five feet from the required side/year yard lines.

BUILDING HEIGHT, AND REQUIRED YARDS, AND STEPBACKS

(The diagram is illustrative)

F. Minimum site landscaping. Decorative hardscape or pervious pavement may not be used to meet minimum landscape requirements as a matter of right.

Exception. Up to 50% of the required landscaping area may be provided through the use of decorative hardscape, and/or pervious pavement areas subject to architectural review or planning commission approval as part of a proposed project (see PHMC § 18.52.030.F).

G. Buildings that incorporate over 50,000 square feet of office space shall include employee showers, clothes changing rooms, and lockers.

H. Buildings that incorporate over 10,000 square feet of office space shall provide eating facilities for employees.

I. City-wide objective design standards. All mixed-use developments that include two-thirds of the total gross floor area dedicated to residential units shall comply with the multifamily residential objective design standards, as adopted by city council resolution.

1. Streamlined mixed-use projects that include two-thirds of the total gross floor area dedicated to residential units. If a proposed mixed-use project that includes two-thirds of the total gross floor area dedicated to residential units qualifies for streamlined permit review, as determined by state law, the zoning administrator shall review the proposed project to verify compliance with the objective design standards applicable to such projects. Proposed mixed-use projects that include two-thirds of the total gross floor area dedicated to residential units that comply with all objective design standards shall be processed ministerially. Qualifying projects that do not comply with the objective design standards shall be subject to the architectural review permit process, as specified in PHMC Chapter 18.115.

J. Storm drains. All storm drain inlets in the MX-N, MX, MX-HD, and MX-VHD districts shall comply with the city’s national pollutant discharge elimination system (NPDES) regulations. (See PHMC Chapter 15.05.)

K. Hotels. Full-service hotels may include restaurants, bars and lounges, massage and spa services, administrative offices, and meeting and banquet rooms.

L. Vehicular easements. A minimum required yard setback shall be provided and measured from any public or private vehicular easement boundary on the property.
