The intent of this chapter is to establish and state the purpose
of the various zoning districts, as well as to describe their boundaries
on the official zoning map.
(Ord. No. 97-11, § 2, 5-5-97)
In order to classify, regulate, restrict and separate the uses
of land and buildings, regulate the height and bulk of buildings and
the area of yards and other open spaces about buildings, and regulate
population density, the following classes of zones are established:
(a) R1 Single-Family Residential District. This district is
intended to promote the development of single-family detached units
located on lots with a minimum lot size of 6,000 square feet, and
a maximum density of 7.26 dwelling units per gross acre.
(b) R2-MD Multiple-Family Residential District, Medium Density. This district is intended to promote the development of multi-family
rental as well as ownership properties on lots with a minimum size
of 12,000 square feet. The maximum density allowed is 3,630 square
feet per dwelling unit, which equals 12 dwelling units per gross acre.
Legal lots existing as of March 16, 1992 with a minimum lot area of
6,000 square feet up to 7,260 square feet are allowed two dwelling
units.
(c) R2-HD Multiple-Family Residential District, High Density. This district is intended to promote the development of multi-family
rental as well as ownership dwelling units on lots with a minimum
size of 12,000 square feet. The maximum density allowed is 3,000 square
feet per dwelling unit, which equals 14.52 dwelling units per gross
acre.
(d) R3 Multiple-Family Residential District. Like the R2-MD
and R2-HD districts, this district is intended to promote the development
of multi-family rental as well as ownership dwelling units. The required
minimum lot size is 12,000 square feet. The maximum density allowed
is 2,178 square feet per dwelling unit, which equals 20 dwelling units
per gross acre.
(e) AP Administrative and Professional District. This district
is intended to establish areas within which public administrative,
professional and business offices may be located. It is the further
purpose of this district to limit the intensity of use within the
district to be compatible with the types of activities generally associated
with office developments.
(f) CL Commercial Limited District. This district is intended
for unique areas of land which, due to the proximity of residential
development or the potential for traffic circulation hazards, require
special precautions to be taken to assure appropriate development.
The district is also intended for industrial areas where commercial
uses must be considered according to their compatibility with existing
or permitted industrial uses.
(g) C1 Local Business District. This district is intended to
meet the local business needs of the community by providing a wide
range of goods and services in a variety of locations throughout the
city. The permitted and conditional uses as well as development standards
are aimed toward reducing impacts on surrounding properties especially
in those areas where residential uses are in the vicinity.
(h) C2 General Business District. This district is intended
to provide for those uses which offer a wide range of goods and services
which are generally less compatible with more sensitive land uses
of a residential or institutional nature.
(i) C1-S Shopping Center District. This district is intended
for large commercial lots constructed as a unified and integrated
development. It is the further purpose to provide a wide range of
goods and services on a community and regional scale.
(j) TC Town Center District. This district is intended to allow
intensely developed mixed commercial and residential uses within a
very limited geographical area bounded by Sunflower Avenue to the
north, 1-405 to the south, Bristol Street to the west, and Avenue
of the Arts to the east. Developments within this designation can
range from one- and two-story office and retail buildings to mid-
and high-rise buildings.
(k) P Off-Street Parking District. This district is intended
to allow parking lots, and buildings incidental to the operation of
the parking lot.
(l) I & R Institutional and Recreational District. This
district is intended to allow land uses which provide recreation,
open space, health and public service uses. Development in this designation
may occur on either public or private property.
(m) I & R-S Institutional and Recreational School District. This district is intended to allow public and private educational
facilities on either public or private property.
(n) MG General Industrial. This district is intended for a variety
of industrial areas which contain a wide range of light and general
industrial activities. Development standards and the approval of conditional
uses shall be aimed toward eliminating possible hazards to adjoining
properties, especially in those areas where residential uses are in
the vicinity.
(o) MP Industrial Park. This district is intended for large,
concentrated industrial areas where the aim of development is to create
a spacious environment in a park-like setting.
(p) PDR-LD Planned Development Residential—Low Density (up to 8
dwelling units per acre); PDR-MD Planned Development Residential—Medium
Density (up to 12 dwelling units per acre); PDR-HD Planned Development
Residential—High Density (up to 20 dwelling units per acre or
higher pursuant to an adopted specific plan); PDR-NCM Planned Development
Residential—North Costa Mesa (25 to 35 dwelling units per acre). These districts are intended to provide for excellence in the design
of residential projects. Within the low-density zone typical designs
include small-lot, single-family detached residential developments
including clustered development, zero lot line development and conventional
development.
Within the medium density, high density, and north Costa Mesa
zones, site design could include single-and multiple-family residential
developments containing any type or mixture of housing units, either
attached or detached, including but not limited to clustered development,
townhouses, patio houses, detached houses, duplexes, garden apartments,
high rise apartments or common interest developments. Complementary
nonresidential uses could also be included in the planned development.
(q) PDC Planned Development Commercial. This district is intended
for retail shops, offices and service establishments, including but
not limited to, hotels, restaurants, theaters, museums, financial
institutions, and health clubs. These uses are intended to serve adjacent
residential areas, as well as the entire community and region. Complementary
residential uses could also be included in the planned development.
(r) PDI Planned Development Industrial. This district is intended
for large, concentrated industrial areas where the aim of development
is to create a spacious environment in a park-like setting.
(s) MU Mixed-Use Overlay. This district may overlay the R2-MD,
R2-HD, R3, CL, C1, C2, MG, PDR-HD, PDR-MD, or I&R districts, and
it is intended to allow development of residential and nonresidential
uses as mixed, integrated projects. This overlay district shall only
be applied to the zoning map in conjunction with the adoption of an
urban plan for the designated area. The urban plan is a regulating
plan that shall define the unique characteristics of the overlay area,
include a matrix of permitted, conditionally permitted, and prohibited
uses and provide development standards. The provisions of the mixed-use
overlay shall be activated by adoption of a master plan.
(t) Institutional and Recreational Multi-Use District. This
district is intended to allow the integration of a variety of land
uses and intensities. This zoning district category includes uses
which are low to moderate in density and intensity and urban in character.
The multi-use center designation is applicable only to the Fairview
Development Center property at 2501 Harbor Boulevard.

filed in the planning division.
(Ord. No. 97-11, § 2, 5-5-97)
The official zoning map may be subdivided into district maps,
and such district maps may be separately used for amending the zoning

All changes shall be made by ordinance adopting an amended zoning
map, or part of the zoning map or district map.
(Ord. No. 97-11, § 2, 5-5-97)
Where uncertainty exists as to the boundaries of any zone shown
on the zoning map, or any district map, the following rules shall
apply:
(a) When
boundaries of zones are approximately following street, alley or lot
lines, such lines shall be construed as the boundaries.
(b) In
the case of undivided properties, or property not yet subdivided,
and a zone boundary divides the lot, the location of the zone boundary,
unless indicated by dimensions, shall be determined by the use of
the scale appearing on the zoning map.
(Ord. No. 97-11, § 2, 5-5-97)
No new building shall be erected, nor shall any building or
land be used for any purpose except as provided and allowed for in
this Zoning Code.
