Title 17 — Development Code

Chapter 17.26 — ESTABLISHMENT OF ZONES

Rancho Cucamonga Zoning Code · 2026-06 edition · ingested 2026-07-06 · Rancho Cucamonga

§ 17.26.010. Chapter purpose.

This chapter establishes the framework of zones within the city and their relationships to the city's general plan land use designations.

(Ord. No. 1000 § 4, 2022)

§ 17.26.020. Zones established.

  • A. Zone purpose. Zones are established in order to classify, regulate, designate, and distribute the uses of land and buildings; to regulate and restrict the height, setbacks and bulk of buildings; to regulate the area of yards and other open spaces around buildings; and to regulate the density of population. The city is divided into zones that are grouped into two categories: (1) base zones and (2) overlay zones. These zones are listed and described in Table 17.26.020-1 (Rancho Cucamonga Zones), along with the general plan land use designation that they implement.

  • B. Base zones. The base zone is the primary zone that applies to a property. Every parcel throughout the city has a base zone that establishes the primary land use type, density, intensity, and site development regulations. Base zones are grouped into five categories as follows:

    1. Residential Zones.

    2. Form-Based Zones.

    3. Industrial Zones.

    4. Open Space Zones.

    5. Special Purpose Zones.

  • C. Overlay zones. The Overlay Zones supplement base zones for one or more of the following purposes:

    1. To allow more flexibility from the standard provisions of the underlying base zone.

    2. To protect unique site features or implement location-specific regulations.

    3. To specify a particular standard or guideline for an area.

  • D. Subzones. Subzones are subsets of the primary zone. Subzones align with the primary zone development standards and uses requirements except where otherwise noted in this title.

  • E. In the event of a conflict between the regulations of the Base Zone and the Overlay Zone, the provisions of the Overlay Zone shall apply.

Form-Based Zones (See Article VIII)
TABLE 17.26.020-1 RANCHO CUCAMONGA ZONES AND SUBZONES
NE2 Neighborhood Estate 2. Low density and intensity residential development on large lots within
interconnected neighborhoods. Context sensitive retail and services uses are allowed in key locations.
NG3 Neighborhood General 3. Medium density and intensity development along certain segments and
nodes of major corridors in proximity to smaller-scale residential neighborhoods. Buildings promote
walkability and contribute to active, vibrant environments while being context-sensitive by transitioning
scale when adjacent to lower density neighborhoods. Uses provide a range of daily needs within
walkable suburban neighborhoods, with some transitional auto-oriented development in outlying areas.
CE1 Center 1. Active, vibrant town centers that promote walkability with neighborhood-serving commercial
and retail uses in proximity to medium density residential development. Buildings front streets and
provide a vibrant, safe street environment for pedestrians and cyclists.
ME1 Mixed Employment 1. Medium intensity development focused on walkable professional offce and
employment uses. Buildings front streets and transition areas from auto-oriented offce parks to mixed-
use, vibrant hubs of activity.
ME2 Mixed Employment 2. Medium to high intensity development focused on professional offce, creative
industrial and maker spaces, and employment uses along active, walkable streets. Buildings front
streets and corridors with tall ground foors that support a mix of uses, entrances, and facades.
CO1 Corridor 1. Medium intensity mixed-use development that transitions existing auto-oriented corridors
and places to vibrant areas that promote walkability. Building and entrance/ facade types are diverse,
contributing to a mix of distinct places along major corridor areas. Buildings front streets and transition
in scale to surrounding neighborhoods with some auto-oriented development along secondary streets.
CO2 Corridor 2. Medium to high intensity mixed-use development along active, walkable corridors and at
key intersections. Buildings front streets and transition in scale to surrounding neighborhoods with
some transitional auto-oriented development along secondary streets.
CE2 Center 2. Mixed-use urban areas with pedestrian-friendly commercial and residential hubs and infll
development along vibrant public spaces that promote walkability. Buildings transition in scale (i.e.,
step up or step down) to surrounding neighborhoods, centers, and districts. Developments support safe
streets for pedestrians and cyclists.
Industrial Zones
NI Neo-Industrial. Designates areas to support a complementary mix of uses such as, research and
development, light and custom manufacturing, engineering and design services, breweries, and maker
spaces, as well as accessory offce, retail and limited residential uses to compliment the primary use;
supportive amenities and services; and convenient transit access. This zone encourages light industrial

activities with low environmental impacts and supports the growth of creative industries, incubator
businesses, and innovative design and manufacturing. The zone can allow for small scale, context
sensitive warehousing, distribution and manufacturing to support small business development.
IE Industrial Employment. Designates areas reserved for manufacturing, processing, construction and
heavy equipment yards, warehousing and storage, e-commerce distribution, light industrial research
parks, automobile and vehicle services, and a broad range of similar clean industrial practices and
processes that typically generate more truck traffc, noise, and environmental impacts than would be
compatible with offce and residential uses. This zone prohibits non-industrial uses, except for
accessory offce and commercial uses (such as restaurants or convenience stores) that support the
employees of the primary industrial use, and on-site caretaker units.
Open Space Zones
OSC Open Space Conservation. Designates areas primarily to protect environmentally sensitive land. The
use regulations, development standards, and criteria encourage preservation of existing conservation
areas and protection of natural resources.
HR Hillside Residential. Designates areas for maintaining natural open space character through protection
of natural landforms; minimizing erosion; providing for public safety; protecting water, fora, and fauna
resources; and establishing design standards to provide for limited development in harmony with the
environment. Allowed density is a maximum of two units per net buildable acre as determined through
the Hillside Development Review process.
P Parks. Designates areas primarily for public parks, public schools, and public facilities. The use
regulations and development standards provide for low intensity development and encourage
educational and recreational activities.
FC/UC Flood Control/Utility Corridor. Designates areas necessary for food control facilities for protection of the
public health, safety, and general welfare as well as utility corridors in which land uses compatible to
both the utility function and surrounding, existing, or proposed land uses are allowed.
Special Purpose Zones
SP Specifc Plan. Designates areas for master planning through the adoption of a specifc plan with unique
land use and development standards for a particular project areas with a minimum of 100 acres.
Overlay Zones
TABLE 17.26.020-1 RANCHO CUCAMONGA ZONES AND SUBZONES

zone protects the ability to maintain such animals, promotes a "rural/farm" character in an urban
setting, and recognizes and encourages the educational and recreational values derived from raising
and maintaining such animals. This zone may be combined with any residential base zone that meets
the overlay zone qualifcations.

zone applies to areas with a slope greater than or equal to eight percent. This zone may be combined
with any residential base zone that meets the overlay zone qualifcations.
