(a) Fire sprinklers shall not be required if they are not required for the
primary dwelling.
(b) However, if the same primary dwelling undergoes significant
remodeling and is required to have fire sprinklers, any ADU created
with or after the remodel must likewise install fire sprinklers.

the applicant shall submit a building permit application to the City, along
with all information and materials prescribed by such application. No
application shall be accepted unless it is completed as prescribed and is

on the lot. Review is limited to whether the proposed ADU or JADU complies
with the requirements of this Section. If an applicant requests a delay, the
time period for the City to review of an application shall be tolled for the
period of the requested delay. If the application to create an ADU or a JADU
unit is submitted with an application to create a new single-family dwelling
on the lot, the Director may delay acting on the application for the ADU or
the JADU until the City acts on the application to create the new single-
family dwelling, but the application to create the ADU or JADU will still be
considered without discretionary review or a hearing.
4. Zoning Conformity. The City shall not require, as a condition of approval of
a permit application for the creation of an ADU or JADU, the correction of
non-conforming zoning conditions.
5. Demolition Permits. A demolition permit for a detached garage that is to be
replaced with an ADU shall be reviewed with the application for the ADU
and issued at the same time.
6. Conformity with State Law. The City shall not apply any requirement or
development standard provided for in this chapter to an ADU or a JADU to
the extent prohibited by any provision of State Law, including, but not limited
to, subdivision (e)(1) of Government Code Section 65852.2.
G. Utilities.
1. ADUs. Unless otherwise mandated by applicable law or the utility provider
or determined by the City's Public Works Director to be necessary, an ADU
may be served by the same water, sewer, and other utility connections
serving the primary dwelling on the property, and the installation of a new
or separate utility connection directly between an ADU and a utility is not
required. However, separate utility connections and meters for ADUs may
be installed at the property owner's option, when permitted by the utility
provider, and subject to the payment of all applicable fees.
2. JADUs. A JADU shall be served by the same water, sewer, and other utility
connections serving the primary single-family dwelling in which it is located,
and no separate utility meters shall be permitted for a JADU.

SECTION 6. Section 9297 (Definitions) of Part 9 of Chapter 2 of Article 9 of the Tustin
City Code is hereby amended by revising the existing definition of “ADU, Converted” or
“Converted ADU” and adding new definitions for “Condominium Project”, “ADU, Statewide
Exemption” or “Statewide Exemption ADU”, “Condominium Project” and “Townhouse” or
“Townhome” to read as follows:
9297 - DEFINITIONS
"ADU, Converted" or "Converted ADU" means an ADU that is constructed within
all or a portion of the permitted existing interior space of an accessory structure or
within a portion of the permitted existing interior space of a dwelling, including
bedrooms, attached or detached garages, storage areas, or similar uses. A
Converted ADU also includes an ADU that is constructed in the same location and
to the same dimensions as a permitted existing structure or portion of a permitted
existing structure.
“Condominium Project” shall have the same meaning as stated in California Civil
Code Section 4125 as that section may be amended from time to time.

800 square feet, 16 feet in height, and with four-foot side and rear setbacks.

SECTION 7. Effective Date. This Ordinance shall take effect on the 31st day after its
adoption. The City Clerk or his or her duly appointed deputy shall certify to adoption of
the Ordinance and cause this Ordinance to be published as required by law.
SECTION 8. CEQA Exemption. The City Council finds that this Ordinance is not
subject to the California Environmental Quality Act (CEQA) pursuant to California Code
of Regulations, Title 14, Chapter 3, Sections 15060 (c)(2) (the activity will not result in a
direct or reasonably foreseeable indirect physical change in the environment) and
15060(c)(3) (the activity is not a project as defined in Section 15378) because it has no
potential for resulting in physical change to the environment, directly or indirectly. The
State Density Bonus Law contains mandatory provisions that the City must implement,
whether or not it adopts its own ordinance, therefore this Ordinance does not create a
new land use. Additionally, pursuant to Section 21080.17 of the California Public
Resources Code, CEQA does not apply to the adoption of an ordinance by a city to
implement the provisions of the State ADU Law.
SECTION 9. Severability. If any section, subsection, sentence, clause, phrase or
portion of this Ordinance is for any reason held out to be invalid or unconstitutional by the
decision of any court of competent jurisdiction, such decision shall not affect the validity
of the remaining portions of this Ordinance. The City Council of the City of Tustin hereby
declares that it would have adopted this Ordinance and each section, subsection, clause,
phrase or portion thereof irrespective of the fact that any one (1) or more sections,
subsections, sentences, clauses, phrases, or portions be declared invalid or
unconstitutional.
PASSED AND ADOPTED, at a regular meeting of the City Council for the City of
Tustin on this 6th day of June, 2023.

set forth in this Article. Notwithstanding the foregoing, when the application
of a development standard related to, lot coverage, open-space, front
setbacks, or minimum lot size would prohibit the construction of an attached
or detached ADU of at least 800 square feet, such standard shall be waived
to the extent necessary to allow construction of a statewide exemption ADU
of up to 800 square feet.
6. Setbacks.
(a) Front Yard Setbacks. New Attached and detached ADUs are subject
to the same minimum front yard setback requirements applicable to
other structures on the lot on which the ADU is located.
(b) Side and Rear Yard Setbacks. Minimum setbacks of no less than four
(4) feet from the side and rear lot lines are required for new attached
and detached ADUs.
(c) Converted ADUs. No setbacks are required for converted ADUs,
provided the side and rear yard setbacks of the existing permitted
converted structure are sufficient for fire and safety, as dictated by the
current applicable uniform building and fire codes.
7. Exterior Access. An attached or converted ADU must have independent
exterior access from the proposed or existing primary dwelling.
8. Passageway. No passageway shall be required in conjunction with the
construction of an ADU. For purposes of this Subsection, "passageway"
means a pathway that is unobstructed clear to the sky and extends from a
street to one (1) entrance of the ADU.
9. Porches and Patios.
(a) An attached or detached ADU may include an attached covered patio
and/or porch, which, if provided, shall be integrated into the design of
the ADU and shall not exceed 200 square feet in size.

1763781.1
(b) In no event shall the total combined area of an ADU and attached
porch and/or patio exceed 1,400 square feet.
10. Architectural Compatibility and Guidelines. To facilitate the development of
ADUs in a manner that ensures reasonable consistency and compatibility
of design, the Director is authorized to develop standard design plans and
criteria for ADUs. ADUs developed in conformance with such standard
plans and criteria shall be deemed to comply with this Subsection.
(a) The design, pitch, color, material, and texture of the roof and eave
details of an Attached or Detached ADU shall be substantially the
same as the primary dwelling.
(b) The color, material, and texture of all building walls, windows, and
doors of an Attached or Detached ADU shall be similar in materials,
colors and finishes to those on the primary dwelling.
(c) The architectural style and scale of an Attached or Detached ADU
shall complement the primary dwelling. To facilitate the development
of ADUs in a manner that ensures reasonable consistency and
compatibility of design, the Director is authorized to develop standard
design plans and criteria for ADUs. ADUs developed in conformance
with such standard plans and criteria shall be deemed to comply with
this Subsection.
(d)
11. Orientation of Detached Accessory Dwelling Structure. A detached ADU
shall be located behind the front building line of the primary residence, so
long as it does not prohibit the creation of a statewide exemption ADU.
12. Multifamily Lots. In addition to the ADU requirements set forth in this
Section, the following requirements shall apply to lots with an existing multi-
family dwelling:
i. Converted ADUs. One (1) or more converted ADUs may be
constructed within portions of existing multi-family dwelling structures
that are not used as livable space including, but not limited to, storage
rooms, boiler rooms, passageways, attics, basements, or garages, if
each unit complies with state building standards for dwellings. No
converted ADUs may be constructed within the existing livable space
of a multi-family dwelling. The number of ADUs permitted under this
subsection shall not exceed twenty-five (25) percent of the existing
multiple-family dwelling units on the lot. For the purpose of calculating
the number of allowable accessory dwelling units: (a) previously

approved ADUs shall not count towards the existing number of
multifamily dwelling units; and (b) fractions shall be rounded down to
the next lower number of dwelling units, except that at least one (1)
converted ADU shall be allowed; or

5. Bathroom Facilities. A JADU may include separate sanitation facilities or
may share sanitation facilities with the proposed or existing single-family
residence in which it is located. If a JADU does not include separate
sanitation facilities, the JADU must include an interior entrance to the
primary dwelling’s main living area.
6. Fire Protection. For purposes of any fire or life protection ordinance or
regulation, a JADU shall not be considered a separate new dwelling unit.
7. Utility Service. For purposes of providing service for water, sewer, or power,
including a connection fee, a JADU shall not be considered a separate or
new dwelling unit.
8. Deed Restriction. Prior to the issuance of a building permit for a JADU, the
owner shall record a deed restriction against the title of the property in the
County Recorder's office with a copy filed with the Director. The deed

the primary residence; this deed restriction may be enforced against
future purchasers.
(c) A restriction on the size and attributes of the JADU that conforms with
this Section.
(d) The JADU may be rented, but may not be rented on a short-term basis

Code Section 65852.26 or by other applicable law, an ADU or JADU may
be rented separate from the primary residence, but may not be sold or
otherwise conveyed separate from the primary residence, and a lot shall not
be subdivided in any manner which would authorize such separate sale or
ownership.
2. No Short-Term Rental Permitted. An ADU or JADU that is rented shall be
rented for a term that is longer than thirty (30) days. Short-term rental (i.e.,
30 days or less) of an ADU or a JADU is prohibited.

Ordinance No. 1535
Page 14
1763781.1
(a) Windows, Doors and Character Defining Features for Historic
Properties - Converted ADU. Windows, doors and character-defining
features for historic properties that are original to the structure are
required to be retained, unless this requirement prevents creation of
the ADU.
(b) Separate Access. An ADU shall provide separate exterior access from
the existing primary residence. Entry doors cannot be on the same
façade as the entry door of the primary residence, unless this
requirement prevents creation of the ADU.
(c) Site Planning - Detached ADU (new construction ADU). A detached
ADU shall be located behind the rear building line of the primary
residence, and be clearly subordinate by location and size, so long as
it does not prohibit the creation of a Statewide Exemption ADU.
G. Permit Application and Review Procedures.
1. Building Permit Required. A building permit is required prior to construction
of an ADU or JADU. Except as otherwise provided in this Section or by State
Law, all building, fire, and related code requirements applicable to habitable
dwellings apply to ADUs and JADUs.
(a) Fire sprinklers shall not be required if they are not required for the
primary dwelling.
(b) However, if the same primary dwelling undergoes significant
remodeling and is required to have fire sprinklers, any ADU created
with or after the remodel must likewise install fire sprinklers.
(c) For ADUs created on lots with multifamily residential structures, the
entire residential structure shall serve as the "primary residence" for
the purposes of this analysis. Therefore, if the multifamily structure is
served by fire sprinklers, fire sprinklers shall be required for the ADU.
2. Application. Prior to the issuance of a building permit for an ADU or JADU,
the applicant shall submit a building permit application to the City, along
with all information and materials prescribed by such application. No
application shall be accepted unless it is completed as prescribed and is
accompanied by payment for all applicable fees.
3. Review. The Director shall consider and approve or disapprove a complete
application for an ADU or JADU without discretionary review or public
hearing within sixty (60) days from the date the City receives a complete
application, when there is an existing single-family or multi-family dwelling

Ordinance No. 1535
Page 15
1763781.1
on the lot. Review is limited to whether the proposed ADU or JADU complies
with the requirements of this Section. If an applicant requests a delay, the
time period for the City to review of an application shall be tolled for the
period of the requested delay. If the application to create an ADU or a JADU
unit is submitted with an application to create a new single-family dwelling
on the lot, the Director may delay acting on the application for the ADU or
the JADU until the City acts on the application to create the new single-
family dwelling, but the application to create the ADU or JADU will still be
considered without discretionary review or a hearing.
4. Zoning Conformity. The City shall not require, as a condition of approval of
a permit application for the creation of an ADU or JADU, the correction of
non-conforming zoning conditions.
5. Demolition Permits. A demolition permit for a detached garage that is to be
replaced with an ADU shall be reviewed with the application for the ADU
and issued at the same time.
6. Conformity with State Law. The City shall not apply any requirement or
development standard provided for in this chapter to an ADU or a JADU to
the extent prohibited by any provision of State Law, including, but not limited
to, Subdivision (e)(1) of Government Code Section 65852.2.
H. Utilities.
1. ADUs. Unless otherwise mandated by applicable law or the utility provider
or determined by the City's Public Works Director to be necessary, an ADU
may be served by the same water, sewer, and other utility connections
serving the primary dwelling on the property, and the installation of a new
or separate utility connection directly between an ADU and a utility is not
required. However, separate utility connections and meters for ADUs may
be installed at the property owner's option, when permitted by the utility
provider, and subject to the payment of all applicable fees.
2. JADUs. A JADU shall be served by the same water, sewer, and other utility
connections serving the primary single-family dwelling in which it is located,
and no separate utility meters shall be permitted for a JADU.
I. Fees.
1. No impact fee is required for an ADU measuring less than 750 square feet.
Any impact fees charged for an ADU of 750 square feet of more shall be
charged proportionately in relation to the square footage of the primary
dwelling.

Ordinance No. 1535
Page 16
1763781.1
2. Construction of an ADU is subject to any applicable fee adopted under the
California Government Code, Title 7, Division 1, Chapter 5 (commencing
with §66000) and Chapter 7 (commencing with § 66012).
3. For purposes of this Subsection, "impact fee" does not include any planning
application fee, plan check fee, or building permit fee.
J. Interpretation. The provisions of this Section shall be interpreted to be consistent
with the provisions of Government Code Sections 65852.2 and 65855.22 and
shall be applied in a manner consistent with State Law.
SECTION 6. Section 9297 (Definitions) of Part 9 of Chapter 2 of Article 9 of the Tustin
City Code is hereby amended by revising the existing definition of “ADU, Converted” or
“Converted ADU” and adding new definitions for “Condominium Project”, “ADU, Statewide
Exemption” or “Statewide Exemption ADU”, “Condominium Project” and “Townhouse” or
“Townhome” to read as follows (new text underlined):
9297 - DEFINITIONS
"ADU, Converted" or "Converted ADU" means an ADU that is constructed within
all or a portion of the permitted existing interior space of an accessory structure or
within a portion of the permitted existing interior space of a dwelling, including
bedrooms, attached or detached garages, storage areas, or similar uses. A
Converted ADU also includes an ADU that is constructed in the same location and
to the same dimensions as a permitted existing structure or portion of a permitted
existing structure
“Condominium Project” shall have the same meaning as stated in California Civil
Code Section 4125 as that section may be amended from time to time.
“ADU, Statewide Exemption” or “Statewide Exemption ADU” means an ADU up to
800 square feet, 16 feet in height, and with four-foot side and rear setbacks.
“Condominium Project” shall have the same meaning as stated in California Civil
Code Section 4125 as that section may be amended from time to time.
“Townhouse” or “Townhome” means a single-family dwelling unit constructed in a
group of three or more attached units in which each unit extends from the foundation
to roof and with a yard or public way on not less than two sides.
SECTION 7. Effective Date. This Ordinance shall take effect on the 31st day after its
adoption. The City Clerk or his or her duly appointed deputy shall certify to adoption of
the Ordinance and cause this Ordinance to be published as required by law.

Ordinance No. 1535
Page 17
1763781.1
SECTION 8. CEQA Exemption. The City Council finds that this Ordinance is not
subject to the California Environmental Quality Act (CEQA) pursuant to California Code
of Regulations, Title 14, Chapter 3, Sections 15060 (c)(2) (the activity will not result in a
direct or reasonably foreseeable indirect physical change in the environment) and
15060(c)(3) (the activity is not a project as defined in Section 15378) because it has no
potential for resulting in physical change to the environment, directly or indirectly. The
State Density Bonus Law contains mandatory provisions that the City must implement,
whether or not it adopts its own ordinance, therefore this Ordinance does not create a
new land use. Additionally, pursuant to Section 21080.17 of the California Public
Resources Code, CEQA does not apply to the adoption of an ordinance by a city to
implement the provisions of the State ADU Law.
SECTION 9. Severability. If any section, subsection, sentence, clause, phrase or
portion of this Ordinance is for any reason held out to be invalid or unconstitutional by the
decision of any court of competent jurisdiction, such decision shall not affect the validity
of the remaining portions of this Ordinance. The City Council of the City of Tustin hereby
declares that it would have adopted this Ordinance and each section, subsection, clause,
phrase or portion thereof irrespective of the fact that any one or more sections,
subsections, sentences, clauses, phrases, or portions be declared invalid or
unconstitutional.
PASSED AND ADOPTED, at a regular meeting of the City Council for the City of
Tustin on this ____ day of _________, 2023.
