days prior to the hearing or determination on the application. The planning division
shall require mailing labels from the project applicant for this purpose. The mailing
labels shall reflect the last known name and address of owner(s) as shown on the
last equalized county assessment roll or by a more current listing.
(2)On-site posting required. Additional notice shall be provided by posting a notice on
each street frontage of the project site, no less than 10 days prior to the date set
for the hearing or determination on the application.
(3)Newspaper publication. When a public hearing is required, notice shall also be
published once in the city in a newspaper of general circulation, no less than 10
days prior to the date set for the public hearing.
(e)Review criteria. Review criteria for all planning applications shall consist of the
following:
(1)Compatible and harmonious relationship between the proposed building and site
development, and use(s), and the building and site developments, and uses that
exist or have been approved for the general neighborhood.
(2)Safety and compatibility of the design of buildings, parking area, landscaping,
luminaries and other site features which may include functional aspects of the site
development such as automobile and pedestrian circulation.
(3)Compliance with any performance standards as prescribed elsewhere in this
Zoning Code.
(4)Consistency with the general plan and any applicable specific plan.
10
(5)The planning application is for a project-specific case and is not to be construed to
be setting a precedent for future development.
(6)When more than one planning application is proposed for a single development,
the cumulative effect of all the planning applications shall be considered.
(7)For residential developments, consistency with any applicable design guidelines
adopted by city council resolution.
(8)For affordable multi-family housing developments which include a minimum of 16
affordable dwelling units at no less than 20 dwelling units per acre, the maximum
density standards of the general plan shall be applied, and the maximum density
shall be permitted by right and not subject to discretionary review during the
master plan application process.
(f)Conditions. The final review authority pursuant to Table 13-29(c), may impose
reasonable conditions to assure compliance with the applicable provisions of this
Zoning Code, and to assure compatibility with surrounding properties and uses and to
protect the public health, safety and general welfare. The final review authority may
also require such written guarantees, cash deposits, recorded land use restrictions,
etc., as may be necessary to assure compliance with the conditions.
(g)Findings. When granting an application for any of the planning applications specified
below, the final review authority shall find that the evidence presented in the
administrative record substantially meets any required conditions listed below. Other
findings may also be required pursuant to other provisions of this Zoning Code.
(1)Major modifications and variance findings:
a.Because of special circumstances applicable to the property, the strict
application of development standards deprives such property of privileges
enjoyed by others in the vicinity under identical zoning classifications.
b.The deviation granted shall be subject to such conditions as will assure that
the deviation authorized shall not constitute a grant of special privileges
inconsistent with the limitation upon other properties in the vicinity and zone
in which the property is situated.
c.The granting of the deviation will not allow a use, density, or intensity which is
not in accordance with the general plan designation and any applicable
specific plan for the property.
(2)Conditional use permit and minor conditional use permit findings:
a.The proposed development or use is substantially compatible with
developments in the same general area and would not be materially
detrimental to other properties within the area.
11
b.Granting the conditional use permit or minor conditional use permit will not be
materially detrimental to the health, safety and general welfare of the public
or otherwise injurious to property or improvements within the immediate
neighborhood.
c.Granting the conditional use permit or minor conditional use permit will not
allow a use, density or intensity which is not in accordance with the general
plan designation and any applicable specific plan for the property.
(3)Density bonus and concession or incentive findings:
a.The request is consistent with State Government Code section 65915 et. seq.
regarding density bonuses and other incentives, the general plan, any
applicable specific plan, and Chapter IX special regulations, Article 4 density
bonuses and other incentives.
b.The requested density bonus and incentive or concession constitute the
minimum amount necessary to provide housing at the target rents or sale
prices and/or a child care facility.
c.The granting of the incentive or concession is required in order to provide for
affordable housing costs, as defined in Health and Safety Code section
50052.5 or for rents for the targeted units.
d.The granting of the incentive or concession and/or the waiver or reduction of
development standards does not have a specific, adverse impact, as defined
in paragraph (2) of subdivision (d) of Government Code section 65589.5 upon
health, safety, or the physical environment, and for which there is no feasible
method to satisfactorily mitigate or avoid the specific adverse impact.
e.The granting of the incentive or concession and/or the waiver or reduction of
development standards does not have an adverse impact on any real
property that is listed in the California Register of Historical Resources.
(4)Lot line adjustment findings: The lot line adjustment and improvements are
consistent with the general plan, any applicable specific plan and this Zoning
Code.
(5)Master plan findings:
a.The master plan meets the broader goals of the general plan, any applicable
specific plan, and the Zoning Code by exhibiting excellence in design, site
planning, integration of uses and structures and protection of the integrity of
neighboring development.
(6)Minor modification findings:
a.The improvement will not be materially detrimental to the health, safety and
general welfare of persons residing or working within the immediate vicinity of
the project or to property and improvements within the neighborhood.
b.The improvement is compatible and enhances the architecture and design of
the existing and anticipated development in the vicinity. This includes the site
planning, land coverage, landscaping, appearance, scale of structures, open
space and any other applicable features relative to a compatible and
attractive development.
12
(7)Mobile home park conversion findings:
a.The impacts of the conversion on the residents of the mobile home park have
been duly considered as required by the State Government Code.
b.The proposed conversion project is consistent with the general plan, any
applicable specific plan and this Zoning Code.
(8)Planned signing program findings:
a.The proposed signing is consistent with the intent of Chapter VIII, Signs, and
the General Plan.
b.The proposed signs are consistent with each other in design and construction
taking into account sign style and shape, materials, letter style, colors and
illumination.
c.The proposed signs are compatible with the buildings and developments they
identify taking into account materials, colors and design motif.
d.Approval does not constitute a grant of special privilege or allow substantially
greater overall visibility than the standard sign provisions would allow.
(9)Reasonable Accommodation findings: Refer to Chapter IX, Article 15.
(10)Common interest development conversion findings:
a.The applicant has submitted an adequate and legally binding plan which
addresses the displacement of long-term residents, particularly senior
citizens and low- and moderate-income families and families with school-age
children; and
13
b.The proposed common interest development conversion project conforms to
adopted general plan policies and any applicable specific plan or urban plan,
and if applicable, increases the supply of lower cost housing in the city and/or
that the proposed conversion project fulfills other stated public goals.
c.The establishment, maintenance, or operation of the project will not be

persons residing or working in the surrounding neighborhood, nor will the
project be detrimental or injurious to property and improvements in the
neighborhood or the general welfare of the city.
d.The overall design and physical condition of the common interest
development conversion project achieves a high standard of appearance,
quality, and safety.
e.The proposed common interest development conversion project conforms to
the Costa Mesa Zoning Code requirements.
f.For a proposed common interest development conversion project that does
not conform to the zoning code requirements, the project due to its
proportions and scale, design elements, and relationship to the surrounding
neighborhood, is of continued value to the community and it contributes to
defining and improving the community as a whole. Deviations from zoning
code requirements are acceptable because it would be impracticable or
physically impossible without compromising the integrity of the overall project
to implement features that could result in conformance with current code
requirements.
g.For a proposed common interest development conversion project located in
an urban plan area, the proposed conversion is consistent with the applicable
mixed-use overlay zoning district. Specifically, the proposed non-residential
conversion project supports a mixed-use development or a similar land use
that is not allowed in the base zoning district, or the proposed conversion
project is a residential common interest development that is permitted by
either the base or overlay zoning district.
(11)Rezone findings: The proposed rezone is consistent with the Zoning Code and the general
plan and any applicable specific plan.
(12)Specific plan conformity review findings: Refer to the applicable specific plan text.

the general plan, any applicable specific plan, and this Zoning Code.
b.The proposed use of the subdivision is compatible with the general plan.
14
c.The subject property is physically suitable to accommodate the subdivision in terms of
type, design and density of development, and will not result in substantial
environmental damage nor public health problems, based on compliance with the
Zoning Code and general plan, and consideration of appropriate environmental
information.
d.The design of the subdivision provides, to the extent feasible, for future passive or
natural heating and cooling opportunities in the subdivision, as required by State
Government Code section 66473.1.
e.The division and development will not unreasonably interfere with the free and
complete exercise of the public entity and/or public utility rights-of-way and/or
easements within the tract.
f.The discharge of sewage from this land division into the public sewer system will not
violate the requirements of the State Regional Water Quality Control Board pursuant to
Division 7 (commencing with State Water Code section 13000).
(h)Decision.
(1)After the public hearing, if required, the final review authority may approve,
conditionally approve or deny any application for the planning application based
upon the standards and intent set forth in the applicable provisions of this Zoning
Code. In the case of a denial, the applicant shall be notified of the circumstances
of the denial.
15
(2)For planning applications which require the planning commission to make a
recommendation to the final review authority, the authority shall not approve any
major change or additions in any proposed planning application until the proposed
change or addition has been referred to the planning commission for a report,
unless the change or addition was previously considered by the planning
commission. It shall not be necessary for the planning commission to hold a public
hearing to review the referral. Failure of the planning commission to report to the
final review authority within 40 days after the referral shall be deemed approval of
the proposed change or addition.
(i)Notice of decision.
(1)Notice of the zoning administrator's decision shall be given within five days of the
decision to the city council, planning commission and to any affected party
requesting the notice. Any member of the planning commission or city council may
request review of a zoning administrator's decision within seven days of the notice
of the decision. No fee shall be charged for such review.
(2)Notice of the planning commission's decision shall be given within five days to the
city council and to any affected party requesting the notice. Any member of the city
council may request review of the decision within seven days of the notice of the
decision. No fee shall be charged for such review.

public hearing or the date of the notice of decision according to the procedures set forth
in Title 2, Chapter IX, Appeal, Rehearing and Review Procedure.
(k)Time limits and extensions.
(1)Planning applications shall run with the land until revoked, except as provided in
this section or in a condition imposed at the time of granting the planning
application.
(2)
a.Unless otherwise specified by condition of approval, any permit or approval not
exercised within 24 months from the actual date of review authority approval shall
expire and become void, unless an extension of time is approved in compliance with
paragraph (4) of this subsection;
b.The permit shall not be deemed "exercised" until at least one of the following has
first occurred:
1.A building permit has been issued and construction has commenced, and
has continued to maintain a valid building permit by making satisfactory
progress as determined by the building official.
2.A certificate of occupancy has been issued.
3.The use is established and a business license has been issued.
4.A time extension has been granted in compliance with paragraph (3)
16
of this subsection.
(3)The time limits specified in paragraph (2) of this subsection shall not apply to

b.For extension requests not to exceed 180 days: The director of development
services may extend the time for an approved permit or approval to be
exercised. Only one request for an extension of 180 days may be approved
by the director. Any subsequent extension requests shall be considered by the
original approval authority.
c.For extensions requests of more than 180 days: The review authority for the
original project shall consider the request to extend the time for an approved
permit or approval to be exercised. A public hearing shall only be held if it
was required on the original application. If notice was required for the original
application, notice of the public hearing shall be given according to the
procedures set forth in this chapter.
(5)Fees for extensions of time for planning applications may be established by
resolution of the city council.
(6)Action on extension request. A permit or approval may be extended beyond the
expiration of the original approval provided the director or the review authority finds
that there have been no changes in the conditions or circumstances of the site, such
as Zoning Code or General Plan amendment or other local and statewide
regulations affecting the approved development standards, or project so that there
would have been ground for denial of the original project or any changes to the
General Plan and/or Zoning Code that would preclude approval of the same project
at the time of the requested extension.
(7)Effect of expiration. After the expiration of the permit or approval, no further work
shall be done on the site and no further use of the site shall occur until a new permit
or approval, or other city permits or approvals are first obtained. Fees for extensions

conforms to the approved set of building plans, applicable conditions of approval and
code requirements.
(n)Reapplication. Upon final denial of any planning application, a new application for
substantially the same planning application may not be filed within six months of the
date of the denial. The development services director shall determine whether the new
application is for a planning application which is substantially the same as a previously
denied application. No decision of the development services director shall be effective
until a period of seven days has elapsed following the written notice of a decision; an
appeal of the decision shall be filed according to the procedures set forth in Title 2,
Chapter IX, Appeal, Rehearing and Review Procedure.
(o)Enforcement authority.
(1)The planning commission may require the modification or revocation of any
planning application and/or pursue other legal remedies as may be deemed
appropriate by the city attorney, if the planning commission finds that the use as
operated or maintained:
a.Constitutes a public nuisance as defined in State Civil Code Sections
3479 and 3480; or
b.Does not comply with the conditions of approval.
(2)The modification or revocation of any permit by the planning commission under
this subsection shall comply with the notice and public hearing requirements set
forth in subsections (c) and (d). The development services director may require
notice for a development review or minor modification, if deemed appropriate.
(p)Amendment to a planning application. Any approved planning application may be
amended by following the same procedure and fee schedule as required for the initial
approval, with the exception of the following two instances:
(1)Minor amendments to conditional use permits shall be processed as minor
conditional use permits; and
(2)Amendments to master plans which comply with section 13-28(f)(1) may be
authorized by the planning division.

CHAPTER IV
CITYWIDE LAND USE MATRIX
§ 13-30. Purpose.
The purpose of this chapter is to provide a comprehensive list of uses which
are permitted, conditionally permitted, or prohibited in the various zoning
districts, as represented by Table 13-30, Land Use Matrix. In evaluating a
proposed use, the following criteria shall also be considered:
(a)Uses determined as permitted may be subject to a discretionary review
when construction is proposed, pursuant to Chapter III, Planning
Applications.
(b)Uses proposed in the planned development zones are subject to
verification of consistency with the master plan adopted for planned
development zones. A proposed use not expressly allowed by the
adopted master plan may require additional discretionary review
pursuant to Table 13-30, Land Use Matrix.
(c)All listed uses in the matrix are subject to verification of compliance with
density and floor area ratio limits, parking requirements and performance
standards which may, in certain cases, prevent the establishment of the
use.
(d)Any proposed use not listed in the Land Use Matrix shall be reviewed by
the development services director to determine its similarity to another
listed use. If no substantial similarity exists, the proposed use shall
require approval of a conditional use permit prior to establishment of the
use.
(e)For the purpose of Table 13-30, Land Use Matrix, the various zoning
districts are labeled as follows:
Residential zones: R1, R2-MD, R2-HD, and R3
Commercial zones: AP, CL, C1, C2, C1-S, and TC
Industrial zones: MG and MP
Planned Development Residential zones: PDR-LD, PDR-MD, PDR-
HD, and PDR-NCM
Planned Development Commercial zone: PDC Planned Development
Industrial zone: PDI
The Parking zone: P
Institutional and Recreational zones: I & R, I & R-S, and I & R-MLT
(f)For zoning districts located in a specific plan area, please refer to the
appropriate specific plan text to determine if any additional regulations
related to land uses are applicable.
(g)For the mixed-use overlay district located in an urban plan area, please
refer to the appropriate urban plan text for additional regulations related
to development standards and allowable land uses as applicable.

portion of the City’s lower-income RHNA and subject to the requirements of
Government Code Section 65583.2 (h) and (i), shown in the Housing Element as
Table B-6: Sites to Accommodate Costa Mesa 2021-2029 RHNA.
(4) “Use by Right” has the same meaning as in Government Code Section 65583.2
Subsection (i) and requires ministerial approval for multifamily housing
developments in which at least 20 percent of the total number of units are
affordable to lower-income households. “Use by Right” means that the review of
an owner-occupied or renter-occupied multifamily residential use may not require
a conditional use permit, planned unit development permit, or other discretionary
review or approval that would constitute a “project” for purposes of Division 13

by a lower-income household regardless of whether the unit was deed-restricted
or that was subject to an affordability covenant or rent control.
(e) Supersession of Overlay
(1) For Lower-Income Housing Element Sites:
• Supersession of Other Zoning Provisions. Projects on Lower-Income
Housing Element Sites shall be governed by this Section, and the
provisions in this Section shall supersede and prevail over any
conflicting provisions of the underlying base zone, including, but not
limited to, minimum residential floor area, minimum residential
capacities and densities, unit caps, trip budgets (if applicable),
ministerial review and approval requirements, and permitted uses, and
all other applicable zoning provisions, such as other urban plans,
overlays, and specific plans, and the provisions of this Article that apply
to non-Lower-Income Housing Element sites. Notwithstanding the
foregoing, to the extent an applicable Specific Plan allows for more
permissive standards or greater heights, projects on Lower-Income
Housing Element Sites may utilize such standards or heights.
4

at least 20 percent of the total dwelling units affordable to Lower-Income
Households shall be processed as a Use by Right, consistent with Government
Code Section 65583.2(h) and (i). Such projects shall be subject only to
ministerial review to verify compliance with all applicable objective design and
development standards in accordance with a Streamlined Development Review
process per CMMC Title 13, Chapter III (Planning Applications). A project that
does not qualify as a Use by Right shall be processed in accordance with a
Development Review process per CMMC Title 13, Chapter III (Planning
Applications).
(2) Subdivision. Any subdivision of a Lower Income Housing Element Site shall
comply with all applicable provisions of CMMC Title 13, Chapter XI
(Subdivisions) and the Subdivision Map Act.
(g) Permitted Uses
(1) Multi-Family Dwellings. Multi-family dwellings shall be permitted on all Housing
Element Sites subject to the requirements of this Section.
(2) Non-Residential Uses. Those non-residential uses permitted in Commercial
Zones in accordance with CMMC Title 13, Chapter IV (Citywide Land Use Matrix)
shall be permitted as part of mixed-use projects on all Housing Element Sites.
(3) Mixed-Use on Lower-Income Housing Element Sites. Mixed-use projects shall
be permitted on Lower-Income Housing Element Sites so long as at least 50
percent of total floor area is provided as residential uses, consistent with
Government Code Section 65583.2, Subsection (h)(1)(B).
(4) Multi-Family Dwellings on Lower-Income Housing Element Sites. Multi-
family dwellings consisting of 100 percent residential uses shall be permitted on
Lower-Income Housing Element Sites, consistent with Government Code Section

Title 13, Chapter IX, Article 15
Reasonable Accommodations
§ 13-200.60 Purpose.
It is the city's policy to provide reasonable accommodation in accordance with federal and state
fair housing laws (42 USC § 3600 et seq., and Government Code § 12900 et seq.) for persons
with disabilities seeking fair access to housing in the application of the city's zoning laws. The
term "disability" as used in this article shall have the same meaning as the terms "disability" and
"handicapped" as defined in the federal and state fair housing laws. The purpose of this article is
to establish the procedure by which a person may request reasonable accommodation, and how
the request is to be processed.
§ 13-200.61 Applicability.
Any person seeking approval to construct and/or modify residential housing for person(s) with
disabilities, and/or operate a residential care facility, group home, or referral facility, which will
substantially serve persons with disabilities may apply for a reasonable accommodation to obtain
relief from a Zoning Code provision, regulation, policy, or condition which causes a barrier to equal
opportunity for housing.
§ 13-200.62 Reasonable Accommodations – Procedure.
(a)Application required. An application for a reasonable accommodation shall be filed and
processed with the Planning Division. The application shall include the following information
and be subject to the determinant factors required by this section.
(b)Submittal requirements. The application shall be made in writing, and shall include the
following information:
(1)The zoning code provision, regulation, policy, or condition from which accommodation
is being requested;
(2)The basis for the claim that the individuals are considered disabled under state or federal
law, and why the accommodation is necessary to provide equal opportunity for housing
and to make the specific housing available to the individuals;
(3)Any other information that the director reasonably determines is necessary for
evaluating the request for reasonable accommodation;
(4)Documentation that the applicant is: (a) an individual with a disability; (b) applying on
behalf of one or more individuals with a disability; or (c) a developer or provider of
housing for one or more individuals with a disability;
(5)The specific exception or modification to the zoning code provision, policy, or practices
requested by the applicant;
(6)Documentation that the specific exception or modification requested by the applicant is
necessary to provide one or more individuals with a disability an equal opportunity to
use and enjoy the residence;
(7)Any other information that is reasonably necessary to determine whether the grounds
for reasonable accommodation identified in subsection (e) of this section and the
findings in subsection (f) of this section can be made, so long as any request for
information regarding the disability of the individuals benefited complies with fair housing
law protections and the privacy rights of the individuals affected.
(c)Fees. No application fee is required.
(d)Director action. Within 60 days of receipt of a completed application, the director shall issue a
written determination to approve, conditionally approve, or deny a request for reasonable
accommodation, and the modification or revocation thereof in compliance with this chapter.
Any appeal to reasonable accommodation request denial or conditional approval shall be
heard with, and subject to, the notice, review, approval, and appeal procedures prescribed for
any other discretionary permit.
(e)Grounds for reasonable accommodation. The following factors shall be considered in
determining whether to grant a requested accommodation:
(1)Is the requested accommodation necessary to afford a disabled person an equal
opportunity to use and enjoy a dwelling? To determine whether the accommodation is
necessary, the director may consider, among other things: The nature of the disability
including the special needs created by the disability, the physical attributes and setting
of the property and structures, the potential benefit that can be accomplished by the
requested accommodation, and alternative accommodations that may provide a
comparable level of benefit.
(2)Is the requested accommodation reasonable? A requested accommodation is not
reasonable if it would impose an undue financial or administrative burden on the City. It
is also not reasonable if it would fundamentally alter a City program, such as the City's
zoning scheme.
a.In considering the financial or administrative burden on the City, the director may
consider, among other things, the extent to which the City would have to dedicate
resources, such as staff time and funds, to grant the request and other requests like
it.
b.In considering the potential alteration to a City program, such as the City's zoning
scheme, the director may consider, among other things, the degree of deviation from
the City's General Plan, if any, the purpose and nature of the particular zoning
district, and with nearby uses. The director may also consider whether the requested
accommodation would potentially have adverse external impacts on properties in the
vicinity.
(f)Findings. The written decision to approve, conditionally approve, or deny a request for
reasonable accommodation shall be based on the following findings, all of which are required
for approval. In making these findings, the director may approve alternative reasonable
accommodations which provide an equivalent level of benefit to the applicant.
(1)The requested accommodation is requested by or on the behalf of one or more
individuals with a disability protected under the fair housing laws.
(2)The requested accommodation is necessary to provide one or more individuals with a
disability an equal opportunity to use and enjoy a dwelling.
(3)The requested accommodation will not impose an undue financial or administrative
burden on the city, as "undue financial or administrative burden" is defined in fair housing
laws and interpretive case law. The determination of whether an accommodation poses
an undue financial and administrative burden or whether a modification poses an undue
financial and administrative burden must be made on a case-by-case basis and must
consider various factors including:
a.The cost of the requested accommodation or the cost of a requested modification if
the City is being requested to pay for the modification;
b.The financial resources of the person or persons who have a duty to provide the
accommodation or the financial resources of the City if it is obligated to pay for the
modification;
c.The benefits that a proposed alternative accommodation or modification would
provide to the individual with a disability;
d.The availability of alternative accommodations or modifications that would effectively
meet the disability-related needs of the individual with a disability;
(4)The requested accommodation demonstrates scale and intensity of use comparable to
adjacent and nearby uses.
(5)The requested accommodation will not, under the specific facts of the case, result in a
direct threat to the health or safety of other individuals or substantial physical damage
to the property of others. The assessment of whether the specific accommodation in
question poses a direct threat to the health or safety of others or would cause substantial
physical damage to the property of others must be based on objective evidence, and not
unsubstantiated inferences. The evidence must be sufficiently recent as to be credible.
The assessment must consider:
a.The nature, duration, and severity of the risk of a direct threat to the health and safety
of others or of substantial physical damage to the property of others;
b.The likelihood that a direct threat to the health or safety of others or substantial
physical damage to the property of others will actually occur; and
c.Whether there are any additional or alternative reasonable accommodations that will
eliminate the direct threat to the health or safety of others or substantial physical
damage to the property of others.
(6)If economic viability is raised by the applicant as part of the applicant's showing that the
requested accommodation is necessary, then a finding that the requested
accommodation is necessary to make facilities of a similar nature or operation
economically viable in light of the particularities of the relevant market and market
participants generally, not just for that particular applicant.
(7)The requested accommodation will not result in a fundamental alteration in the nature
of the City's zoning program.
(g)The City may consider, but is not limited to, the following factors in determining whether the
requested accommodation would require a fundamental alteration in the nature of the City's
zoning program:
(1)Whether the requested accommodation would fundamentally alter the character of the
neighborhood.
(2)Whether the accommodation would result in a substantial increase in traffic or
insufficient parking.
(3)Whether granting the requested accommodation would substantially undermine any
express purpose of either the City's general plan or an applicable specific plan.
(4)Whether the requested accommodation would create an institutionalized environment
due to the number of and distance between facilities that are similar in nature or
operation.
(5)Any other factors that would cause a fundamental alteration in the city's zoning program,
as may be defined in the Fair Housing Law.
§13-200.63 Severability.
Should any section, subsection, clause, or provision of this article for any reason be held to be
invalid or unconstitutional, such invalidity or unconstitutionality shall not affect the validity or
constitutionality of the remaining portions of this article; it being hereby expressly declared that
this article, and each section, subsection, sentence, clause and phrase hereof would have been
prepared, proposed, approved and ratified irrespective of the fact that any one or more sections,
subsections, sentences, clauses or phrases be declared invalid or unconstitutional. This article
shall be prospective in application from its effective date.

§ 13-271 Purpose.
The purpose of this article is to set forth the provisions for assuring an adequate transportation
system in conjunction with new development.
(Ord. No. 97-11, § 2, 5-5-97)
§ 13-272 Definitions.
For the purpose of this article, the following definitions shall apply:
Development project. This article applies to the following development project approvals:
general plan amendments, specific plans, master plans, rezones, development reviews,
variances, use permits, major modifications, minor modifications and development agreements,
unless otherwise exempted by section 13-276, Exemptions.
Intersection. The general area where two or more roadways join or cross.
Measurable traffic. A volume of traffic which will result in a 0.01 or greater increase in the peak
period volume to capacity ratio at any given signalized intersection.
Potentially deficient intersection. An intersection identified in the general plan for which the
standard level of service may not be feasible upon general plan buildout. The intersection
volume to capacity ratios identified in the general plan shall not be exceeded for these
intersections.
Pro rata. A proportionate share based on a development project's impacts.
Standard level of service. The standard level of service shall be level of service "D" or better
(0.90 or less volume to capacity ratio) for all signalized arterial intersections within the city
during peak hours Monday through Friday with the exception of those intersections identified as
potentially deficient in the general plan. Levels of service shall be defined and computed using
the Intersection Capacity Utilization (ICU) methodology.
Transportation demand management program. A series of required and/or voluntary actions
which reduce the vehicle trip generation rate of a specific use or uses of land.
(Ord. No. 97-11, § 2, 5-5-97)
§ 13-273 Comprehensive transportation system improvement program.
(a)Purpose. The comprehensive transportation system improvement program shall be adopted
by resolution of the city council which addresses the cumulative impacts of development in a
defined impact area. This program shall mandate circulation improvements, including freeway
improvements, to ensure that the master plan of highways is constructed and that the standard
level of service is achieved and will be maintained at all intersections in the defined impact area
in accordance with the general plan. For those intersections identified as potentially deficient,
the program shall identify the maximum improvements feasible in accordance with the general
plan. The program shall address the funding, construction and maintenance of transportation
facilities to implement the master plan of highways. The program shall be updated on an annual
basis.
2
(b) Relationship to development fee program. The comprehensive transportation system
improvement program shall be utilized to determine the pro rata share of the cost of necessary
improvements attributable to development projects as described in section 13-274,
Development fee program.
(c) Development phasing and performance monitoring report. Each year the city shall prepare a
development phasing and performance monitoring report which shall be used to update the
comprehensive transportation system improvement program.
(d) Interim approval procedure. Until such time as this program is adopted, development
projects not exempted pursuant to section 13-276, Exemptions, may be approved if the city
adopts findings that the development projects are consistent with the provisions of this article.
(Ord. No. 97-11, § 2, 5-5-97)
§ 13-274 Development fee program.
(a) Establishment of development impact fee program. A development impact fee program shall
be established by resolution of the city council based on the comprehensive transportation
system improvement program. The program shall set forth the basis for the fee as required by
State Government Code section 66001. The program shall establish guidelines for payment,
accounting, and refund of the fees collected as required by State Government Code Sections
66001, 66006 and 66007.
(b) Updates of fee. On an annual basis, the city council shall review this fee program, as
required by State Government Code section 66002, to determine whether the fee amounts are
reasonably related to the impacts of development projects and whether the described public
facilities are still needed.
(c) Limited use of fees. The revenues raised by payment through this fee program shall be
placed in a separate and special account and such revenues, along with any interest earnings
on that account, shall be used solely to:
(1) Pay for the city's future construction of facilities or to reimburse the city for those facilities,
described or listed in the program, constructed by the city with funds advanced by the city from
other sources; or
(2) Reimburse developers who have been required or permitted to install such listed facilities to
the extent the actual cost of the facilities installed by the developer exceeds the impact fee
obligation of the development project.
(d) Developer construction of public facilities. Whenever the conditions of approval of a
development project require direct construction of a public transportation facility (see section 13-
275(c), Development project review procedures) described or listed in the comprehensive
transportation system improvement program, a credit or reimbursement, as applicable, shall be
given against the development impact fee, which would have been charged to the development
project under the program, for actual construction costs incurred by the developer. The
reimbursement and/or credit amount shall not include any improvements the city can require
from the development project under the Subdivision Map Act, or the portion of the improvement
deemed to be an on-site improvement that is not included in the comprehensive transportation
system improvement program.
(e) Fee adjustments. A developer of any development project subject to the fee program
provided in this article may apply to the city council for:
3
(1)A waiver of the fee, or portion of the fee, based upon adequate documentation of the
absence of any reasonable relationship or nexus between the circulation impacts of that
development project and either the amount of the fee charged or the type of facilities to be
financed; or
(2)A reduction of the fee based upon the implementation of a transportation demand
management program, as described in section 13-275(d), Development project review
procedures.
(3)The application for a fee waiver shall be made in writing and filed with the city clerk not later
than:
a. 10 days prior to the public hearing on the development permit application for the project; or
b. If no development permit is required, at the time of the filing of the request for a building
permit.
(4)The application shall state in detail the factual basis for the claim of waiver. The city council
shall consider the application at the public hearing on the permit application held within 60 days
after the filing of the application. The decision of the city council shall be final. If a waiver is
granted, any change in use or increase in building intensity within the development project shall
invalidate the waiver of the fee, and the developer shall be obligated to pay the full amount of
the fee attributed to the development project, including the change in use or increase in
intensity, as provided by this article.
(f) Fee refunds. A refund shall be made when a building permit expires and no extensions have
been granted for a development project for which the funds have been collected and the
development project has not been constructed.
(g) Fees for phased development projects. Where there is a requirement imposed upon a
phased development project pursuant to this article for the payment of traffic impact fees into a
comprehensive transportation system improvement program, such fees may be payable on a
pro rata basis as each phase of the project is completed, in conjunction with the improvements
accomplished.
(Ord. No. 97-11, § 2, 5-5-97)
§ 13-275 Development project review procedures.
(a)Traffic study required. A traffic impact study shall be required for all development projects
estimated by the public services director to generate 100 or more vehicle trip ends during a
peak hour. Traffic studies may also be required for smaller projects at the discretion of the public
services director. The cost of the study shall be paid for by the developer. The study area and
number of intersections to be analyzed shall be determined by the public services director and
the study area shall be reasonably related to the estimated impacts attributed to the
development project. The traffic study shall also identify mitigation measures that are
reasonably related to the development project's traffic impacts.
(b) Mitigation measures. Mitigation measures for development projects shall consist of either
payment of a development impact fee and/or construction of circulation improvements. The
necessary circulation improvements may be designed and constructed by the developer as
determined by the city. These mitigation measures shall be incorporated as conditions of the
development project's approval. Table 13-275 indicates the criteria for either requiring payment
of a development impact fee and/or construction of circulation improvements.
4
(c)Approval criteria. A development project may be approved if as a condition of approval it is
required to construct a circulation improvement and/or pay a development impact fee, as shown
in Table 13-275, and if a finding is made that the development project's impacts will be mitigated
at all affected intersections within three years of issuance of the first building permit for the
development project, as described in subsection (b), unless additional right-of-way or
coordination with other government agencies is required to complete the improvement. If right-
of-way acquisition or coordination with other governmental agencies delays the improvement
construction, appropriate measures shall be taken to ensure that the improvement construction
occurs in a timely manner. Circulation improvements may be required sooner if, because of
extraordinary traffic generation characteristics of the development project or extraordinary
impacts to the surrounding circulation system, the circulation improvements are necessary to
prevent significant adverse impacts. For phased development projects, the construction of
circulation improvements may be phased as well based upon the findings of the traffic study.
When a development project affects a potentially deficient intersection, the development
project's impacts shall be mitigated such that the intersection volume to capacity ratios identified
in the general plan shall not be exceeded.
(d)Transportation demand management program. Where a transportation demand
management program is used to reduce vehicle trips related to a development project, the
program shall comply with the following:
(1)A conditional use permit for the development project and program must be approved by the
planning commission consistent with the requirements of subsection (c). An annual report shall
be prepared for the city at the expense of the property owner, to show whether the vehicle trip
reduction identified in the program has been achieved and maintained.
(2) If the annual report demonstrates that the vehicle trip reductions identified in the program
have not occurred, the conditional use permit shall be reevaluated and additional conditions
imposed by the planning commission in order to meet the requirements of this article.
(3)The traffic impact development fees required under this article shall be based on the trip
generation forecast without consideration of estimated reductions associated with a
transportation demand management program. An application for a fee reimbursement may be
approved by the city council pursuant to section 13-274(e), Development fee program, based
upon documentation of average annual trip reduction over a three-year period as reported in the
annual monitoring report referenced in section 13-273(c), Comprehensive transportation system
improvement program.
(e) Change of use. Each development project approved under this article shall be reevaluated
by the public services director when any change in use occurs which may increase the project's
traffic generation. The purpose of this reevaluation is to assure that traffic capacity is available in
the transportation system. Any increase in traffic generation by the change of use shall be
subject to review by the appropriate reviewing authority who may impose additional conditions
on the development project for the mitigation of the increased traffic generation.

Title 13, Chapter XV,
Group Homes
§ 13-310Purpose.
This chapter is intended to preserve the residential character of single-family residential
neighborhoods and to further the purposes of the FEHA, the FHAA and the Lanterman Act by,
among other things: (1) ensuring that group homes are actually entitled to the special
accommodation and/or additional accommodation provided under the Costa Mesa Municipal
Code and not simply skirting the city's boarding house regulations; (2) limiting the secondary
impacts of group homes by reducing noise and traffic, preserving safety and providing adequate
on street parking; (3) providing an accommodation for the handicapped that is reasonable and
actually bears some resemblance to the opportunities afforded non-handicapped individuals to
use and enjoy a dwelling unit in a single-family neighborhood; and (4) to provide comfortable living
environments that will enhance the opportunity for the handicapped and for recovering addicts to
be successful in their programs.
§13-311 Special use permit required.
(a)A group home that may otherwise be considered an unpermitted use may locate in an R1
zone with a special use permit provided:

home until this information has been provided and such persons shall be responsible for
updating any of this information to keep it current.
(2)The group home has six or fewer occupants, not counting a house manager, but in no
event shall have more than seven occupants. If the dwelling unit has an accessory
dwelling unit, occupants of both units will be combined to determine whether or not the
limit of six occupants has been exceeded.
(3)The group home shall not be located in an accessory dwelling unit unless the primary
dwelling unit is used for the same purpose.
(4)The group home has a house manager who resides at the group home or any multiple
of persons acting as a house manager who are present at the group home on a 24 hour

(9)The property must be fully in compliance with all building codes, municipal code and
zoning.
(10)At least 48 hours prior to an occupant's eviction from or involuntary termination of
residency in a group home, the operator thereof shall:
i.Notify the person designated as the occupant's emergency contact or contact of
record that the occupant will no longer be a resident at the home;
ii.Contact the Orange County Health Care Agency OC Links Referral Line and/or
another entity designated by the City to determine the services available to the
occupant, including, but not limited to, alcohol and drug inpatient and outpatient
treatment;
iii.Notify the city's Network for Homeless Solutions that an occupant is no longer a
resident at the home, and determine the services available therefrom;
iv.Provide the information obtained from paragraphs ii and iii of this subsection (a)(10)
and any other treatment provider or service to the occupant prior to his or her release
on a form provided by the City and obtain the occupant's signed acknowledgement
thereon;
v.Provided, however, that if the occupant's behavior results in immediate termination
of residency pursuant to rules approved by the City as part of the special use permit

permanent address or otherwise has no permanent address, then the operator shall
make available to the occupant transportation to another group home or residential
care facility that has agreed to accept the occupant.
(12)The group home operator shall maintain records for a period of one year following
eviction from or involuntary termination of residency of an occupant that document
compliance with subsections (a)(10) and (a)(11) of this section; provided, however, that
nothing herein shall require an operator of a group home to violate any provision of state
or federal law regarding confidentiality of health care information. The group home
operator may not satisfy the obligations set forth in subsection (a)(11) of this section by
providing remuneration to the occupant for the cost of transportation.
(13)All drivers of vehicles picking up or dropping off persons at a group home shall comply
with all applicable provisions of this Code and the Vehicle Code, including, but not limited
to, those provisions regulating licensure and parking, standing and stopping.

possession or use of prescription medications is prohibited except for the person to
whom they are prescribed, and in the amounts/dosages prescribed. These rules and
regulations shall be posted on site in a common area inside the dwelling unit. Any
violation of this rule must be cause for eviction under the sober living home's rules
for residency and the violator cannot be re-admitted for at least 90 days. Any second
violation of this rule shall result in permanent eviction. Alternatively, the sober living
home must have provisions in place to remove the violator from contact with the
other residents until the violation is resolved.

of Penal Code section 290 does not exceed the limit set forth in Penal Code section
3003.5 and does not violate the distance provisions set forth in Penal Code section
3003.
v.The sober living home shall have a written visitation policy that shall preclude any
visitors who are under the influence of any drug or alcohol.
vi.The sober living home shall have a good neighbor policy that shall direct occupants
to be considerate of neighbors, including refraining from engaging in excessively
loud, profane or obnoxious behavior that would unduly interfere with a neighbor's
use and enjoyment of their dwelling unit. The good neighbor policy shall establish a
written protocol for the house manager/operator to follow when a neighbor complaint
is received.
vii.The sober living home shall not provide any of the following services as they are
defined by section 10501(a)(6) of Title 9, California Code of Regulations:
detoxification; educational counseling; individual or group counseling sessions; and
treatment or recovery planning.
(15)An applicant may seek relief from the strict application of this section by submitting an
application to the director setting forth specific reasons as to why accommodation over
and above this section is necessary under state and federal laws, pursuant to section 13-
200.62.

is in compliance or has agreed to comply with subsections (a)(1) through (a)(14) of this
section. At least 10 days prior to issuing a special use permit, the director shall cause a
courtesy written notice to be mailed to the owner of record and occupants of all properties
within 100 feet of the location of the group home. The issuance of the special use permit shall
be denied upon a determination, and if already issued shall be revoked upon a hearing, by
the director if any of the following circumstances exist:
(1)Any owner/operator or staff person has provided materially false or misleading
information on the application or omitted any pertinent information;
(2)Any owner/operator or staff person has an employment history in which he or she was
terminated during the past two years because of physical assault, sexual harassment,

i.Any sex offense for which the person is required to register as a sex offender under
California Penal Code section 290 (last 10 years);
ii.Arson offenses—Violations of Penal Code Sections 451—455 (last seven years); or
iii.Violent felonies, as defined in Penal Code section 667.5, which involve doing bodily
harm to another person (last 10 years).

(4)Any owner/operator or staff person is on parole or formal probation supervision on the
date of the submittal of the application or at any time thereafter.
(5)The owner/operator accepts residents, other than a house manager, who are not
handicapped as defined by the FHAA and FEHA.
(6)A special use permit for a sober living home shall also be denied upon a determination,
and if already issued, any transfer shall be denied or revoked, upon a hearing, by the
director that any of the following additional circumstances exist:
i.Any owner/operator or staff person of a sober living home is a recovering drug or
alcohol abuser and upon the date of application or employment has had less than
one full year of sobriety.
ii.The owner/operator of a sober living home fails to immediately take measures to
remove any resident who uses alcohol or illegally uses prescription or non-
prescription drugs, or who is not actively participating in a legitimate recovery
program from contact with all other sober residents.
iii.The sober living home, as measured by the closest property lines, is located within
650 feet of any other sober living home or state licensed alcoholism or drug abuse
recovery or treatment facility. If a state-licensed alcoholism or drug abuse recovery
or treatment facility moves within 650 feet of an existing sober living home this shall
not cause the revocation of the sober living home's permit or be grounds for denying
a transfer of such permit.
(7)For any other significant and/or repeated violations of this section and/or any other
applicable laws and/or regulations, including, but not limited to, failure to comply with the
provisions of subsections (a)(10) through (13).
