EXHIBIT A
(Continued on following page)
7 O 1113
ADU CODE AMENDMENTS
(Begins on following page)
Section 9-3.501.1 Accessory Dwelling Units
(a) Purpose. The purpose of this section is to allow and regulate accessory dwelling
units (ADUs) and junior accessory dwelling units (JADUs) in compliance with
California Government Code sections 65852.2 and 65852.22.
(b) Effect of Conforming. An ADU or JADU that conforms to the standards in this
section will not be:
(1) Deemed to be inconsistent with the City’s general plan and zoning designation
for the lot on which the ADU or JADU is located.
(2) Deemed to exceed the allowable density for the lot on which the ADU or JADU
is located.
(3) Considered in the application of any local ordinance, policy, or program to limit
residential growth.
(4) Required to correct a nonconforming zoning condition, as defined in
subsection (c)(7) below. This does not prevent the City from enforcing
compliance with applicable building standards in accordance with Health and
Safety Code section 17980.12.
(c) Definitions. As used in this section, terms are defined as follows:
(1) “Accessory dwelling unit” or “ADU” means an attached or a detached
residential dwelling unit that provides complete independent living facilities for
one or more persons and is located on a lot with a proposed or existing primary
residence. An accessory dwelling unit also includes the following:
(A) An efficiency unit, as defined by Section 17958.1 of the California
Health and Safety Code; and
(B) A manufactured home, as defined by Section 18007 of the California
Health and Safety Code.
(2) “Accessory structure” means a structure that is accessory and incidental to a
dwelling located on the same lot, including attached or detached garages,
covered patios, storage sheds and cabanas.
(3) “Building height” means the vertical distance from finished grade or flood
protection elevation to the topmost point of the roof of a building or to the
highest point of a structure other than a building, as shown in Figure 2.
8 O 1113
Chimneys, finials, and other rooftop architectural projections are not included
in determining building height.
For structures in hillside areas, allowable building height shall be determined
by connecting an imaginary line, at the applicable building height standard,
between a series of vertical lines drawn at the uppermost and the lowermost
finish grades of a building (typically measured at a point five (5) feet away from
the vertical building wall), as shown in Figure 3. For purposes of this definition,
“hillside area” means an area in which the average slope of the building
footprint area is ten (10) percent or more. For structures in hillside areas that
are constructed on a foundation system that include one or more retaining
walls or other retaining system, the measurement to establish allowable
building height shall be measured from five (5) feet outside of the retaining wall
or system used to support the building.
Figure 2: Building Height on Level Lot
Figure 3: Building Height on Hillside
9 O 1113
(4) “Complete independent living facilities” means permanent provisions for
living, sleeping, eating, cooking, and sanitation. Cooking provisions shall
include the use of built-in appliances such as built-in ovens or stoves, as
opposed to counter-top ovens and hot plates.
(5) “Efficiency kitchen” means a kitchen that includes each of the following:
(A) A cooking facility with appliances.
(B) A food preparation counter that is of reasonable size in relation to the
size of the junior accessory dwelling unit.
(C) Food storage cabinets that are of reasonable size in relation to the size
of the junior accessory dwelling unit.
(6) “Junior accessory dwelling unit” or “JADU” means a residential unit that
satisfies all of the following:
(A) It is no more than 500 square feet in size,
(B) It is contained entirely within an existing or proposed single-family
structure. An enclosed use within the residence, such as an attached
garage, is considered to be a part of and contained within the single-
family structure.
(C) It includes its own separate sanitation facilities or shares sanitation
facilities with the existing or proposed single-family structure.
(D) If the unit does not include its own separate bathroom, then it contains
an interior entrance to the main living area of the existing or proposed
single-family structure in addition to an exterior entrance that is
separate from the main entrance to the primary dwelling.
(E) It includes an efficiency kitchen, as defined in subsection (c)(5) above
(7) “Nonconforming zoning condition” means a physical improvement on a
property that does not conform with current zoning standards regardless of
whether the nonconforming condition was lawfully created in compliance with
all applicable ordinances and laws at the time the lot or physical improvement
was created.
(8) “Public transit stop” means a location, including, but not limited to, a bus stop
or train station, where the public may access buses, trains, subways, and other
forms of transportation that charge set fares, run on fixed routes, and are
available to the public.
(d) Review Process. The following two review processes apply to proposed ADUs and
JADUs under this section:
10 O 1113
(1) Building Permit Review. The following four categories of ADUs or JADUs are
allowed with only a building permit if all of the general requirements listed in
subsection (e) below are met:
(A) Integrated ADUs and JADUs on Single-family Lots: One detached
or attached ADU with no maximum size limit and one JADU is allowed
on a lot that contains a proposed or existing single-family dwelling,
regardless of the underlying residential zoning, if the integrated ADU
and JADU meets all of the following requirements:
(i) Location: The ADU and JADU is located either:
a. within the space of a proposed single-family dwelling; or
b. within the space of an existing single-family dwelling; or
c. In the case of an ADU only, within the space of an
accessory structure as defined in section(C)(2), plus up to
150 square feet of additional habitable floor area to
accommodate ingress and egress.
(ii) Has exterior access that is independent of that for the single-
family dwelling; and,
(iii) Has minimum interior side and rear setbacks sufficient for fire
and safety, as dictated by applicable building and fire codes.
(iv) The JADU complies with the requirements of Government Code
Section 65852.22.
(B) New Detached ADUs on Single-family Lots: One detached, new-
construction ADU is allowed on a lot with a proposed or existing single-
family dwelling (in addition to any JADU that might otherwise be
established on the lot under subsection (d)(1)(A) above), regardless of
the underlying residential zoning, provided the detached ADU meets
each of the following requirements:
(i) The side- and rear-yard setbacks are at least 4-feet; and
(ii) The total floor area is 800 square feet or smaller; and
(iii) The peak height above grade does not exceed the applicable
height limit in subsection (e)(6) below.
(C) Converted ADUs on Multi-family Lots: One or more ADUs within
portions of existing multi-family structures that are not used as livable
space, regardless of the underlying residential zoning. Non-livable
space that may be converted to an ADU may include, but is not limited
to, storage rooms, boiler rooms, passageways, attics, basements, or
11 O 1113
garages, provided each converted ADU complies with state building
standards for dwellings. At least one converted ADU is allowed within
an existing multi-family structure, and the maximum number of ADUs
that may be created within an existing multi-family structure is equal to
25 percent of the existing multi-family dwelling units within that
structure.
(D) New Detached ADUs on Multi-family Lots: No more than two
detached new construction ADUs are allowed on a lot that has an
existing or proposed multi-family structure, regardless of the underlying
residential zoning, provided each new detached ADU meets both of the
following requirements:
(i) The side and rear yard setbacks are at least four feet. If the
existing multi-family structure has a rear or side yard setback of
less than four feet, the City will not require any modification to
the multi-family structure as a condition of approving the ADU.
(ii) The peak height above grade does not exceed the applicable
height limit provided in subsection (e)(6) below.
(2) Zoning-Compliance Review.
(A) Except as allowed under subsection (d)(1) above, no ADU may be
created without both a building permit and a zoning-compliance review
to ensure that the proposed ADU is in compliance with the standards
set forth in subsections (e) and (f) below.
(B) The City may charge an application fee, adopted by City Council
resolution, to reimburse it for costs incurred in the zoning-compliance
review of an ADU.
(C) The zoning-compliance review of an ADU is a ministerial action, without
discretionary review or a hearing.
(e) General ADU and JADU Requirements. The following requirements apply to all
ADUs and JADUs that are approved under subsections (d)(1) or (d)(2) above:
(1) Zoning.
(A) An ADU or JADU subject only to a building permit under subsection
(d)(1) above may only be created on a lot located within a single-family
or multi-family zoning district. The City has no mixed-use zoning district.
(B) An ADU or JADU subject to zoning-compliance review under
subsection (d)(2) above may only be created on a lot in areas zoned to
allow single family or multi-family dwelling residential use.
12 O 1113
(2) Timing. The City must approve or deny an application to create an ADU or
JADU within 60 days from the date that the City receives a completed
application. If the City has not approved or denied the completed application
within 60 days, the application is deemed approved unless either:
(i) The applicant requests a delay, in which case the 60-day time
period is tolled for the period of the requested delay, or
(ii) When an application to create an ADU or JADU is submitted with
a permit application to create a new single-family or multifamily
dwelling on the lot, the City may delay acting on the application
for the ADU or JADU until the City acts on the permit application
to create the new single-family or multifamily dwelling, but the
application to create the ADU or JADU will still be considered a
ministerial action without discretionary review or a hearing.
(3) Application Denial; Comments. If the City denies an application to create an
ADU or JADU, the City must provide the applicant with comments that include,
among other things, a list of all the defective or deficient items and a
description of how the application may be remedied by the applicant. Notice of
the denial and corresponding comments must be provided to the applicant
within the 60-day time period established by subsection (e)(2) above.
(4) Demolition Permits. A demolition permit for a detached garage that is to be
replaced with an ADU is reviewed with the application for the ADU and issued
at the same time.
(5) Fire Sprinklers.
(A) Fire sprinklers are required in an ADU if sprinklers are required in the
primary residence.
(B) The construction of an ADU does not trigger a requirement for fire
sprinklers to be installed in the existing primary dwelling.
(6) Height.
(A) Except as otherwise provided by subsections (e)(6)(B) and (e)(6)(C)
below, a detached ADU created on a lot with an existing or proposed
single family or multifamily dwelling unit may not exceed 16 feet in
height.
(B) A detached ADU may be up to 18 feet in height if it is created on a lot
with an existing or proposed single family or multifamily dwelling unit
that is located within one-half mile walking distance of a major transit
stop or a high quality transit corridor, as those terms are defined in
Section 21155 of the Public Resources Code, and the ADU may be up
to two additional feet in height (for a maximum of 20 feet) if necessary
13 O 1113
to accommodate a roof pitch on the ADU that is aligned with the roof
pitch of the primary dwelling unit.
(C) A detached ADU created on a lot with an existing or proposed
multifamily dwelling that has more than one story above grade may not
exceed 18 feet in height.
(D) An ADU that is attached to the primary dwelling may not exceed 25 feet
in height or the height limitation imposed by the underlying zone that
applies to the primary dwelling, whichever is lower. Notwithstanding the
foregoing, ADUs subject to this subsection (e)(6)(D) may not exceed
two stories.
(7) Rental Term. No ADU or JADU may be rented for a term that is shorter than
30 calendar days. This prohibition applies regardless of when the ADU or
JADU was created.
(8) No Separate Conveyance. An ADU or JADU may be rented, but, except as
otherwise provided in Government Code Section 65852.26, no ADU or JADU
may be sold or otherwise conveyed separately from the lot and the primary
dwelling (in the case of a single-family lot) or from the lot and all of the
dwellings (in the case of a multi-family lot).
(9) Owner Occupancy.
(A) An ADU permitted after January 1, 2020, but before January 1, 2025,
is not subject to an owner-occupancy requirement.
(B) Unless applicable law requires otherwise, all ADUs that are created on
or after January 1, 2025 are subject to an owner-occupancy
requirement. A natural person with legal or equitable title to the property
must reside on the property as the person’s legal domicile and
permanent residence.
(C) As required by state law, all JADUs regardless of when they are created
are subject to an owner-occupancy requirement. A natural person with
legal or equitable title to the property must reside on the property, in
either the primary dwelling or the JADU, as the person’s legal domicile
and permanent residence. The owner-occupancy requirement of this
paragraph does not apply if the property is entirely owned by a
governmental agency, land trust, or housing organization.
(10) Deed Restriction. Prior to issuance of a building permit for an ADU or JADU,
a deed restriction must be recorded against the title of the property in the
County Recorder’s office and a copy filed with the Director of Development
Services. The deed restriction must run with the land and bind all future
owners. The form of the deed restriction will be provided by the City and must
provide that:
14 O 1113
(A) Except as otherwise provided in Government Code Section 65852.26,
the ADU or JADU may not be sold separately from the primary dwelling;
and,
(B) The ADU or JADU is restricted to the approved size and to other
attributes allowed by this section; and,
(C) The deed restriction runs with the land and may be enforced against
future property owners; and,
(D) The deed restriction may be removed if the owner eliminates the ADU
or JADU, as evidenced by, for example, removal of the kitchen facilities.
To remove the deed restriction, an owner may make a written request
of the Director of Development Services, providing evidence that the
ADU or JADU has in fact been eliminated. The Director may then
determine whether the evidence supports the claim that the ADU or
JADU has been eliminated. Appeal may be taken from the Director’s
determination consistent with other provisions of this Code. If the ADU
or JADU is not entirely physically removed, but is only eliminated by
virtue of having a necessary component of an ADU or JADU removed,
the remaining structure and improvements must otherwise comply with
applicable provisions of this Code; and,
(E) The deed restriction is enforceable by the Director of Development
Services or his or her designee for the benefit of the City. Failure of the
property owner to comply with the deed restriction may result in legal
action against the property owner, and the City is authorized to obtain
any remedy available to it at law or equity, including, but not limited to,
obtaining an injunction enjoining the use of the ADU or JADU in violation
of the recorded restrictions or abatement of the illegal unit.
(11) Building & Safety.
(A) Must comply with building code. Subject to subsection (e)(11)(B)
below, all ADUs and JADUs must comply with all local building code
requirements.
(B) No change of occupancy. Construction of an ADU does not constitute
a Group R occupancy change under the local building code, as
described in Section 310 of the California Building Code, unless the
building official or Code Enforcement Division officer makes a written
finding based on substantial evidence in the record that the construction
of the ADU could have a specific, adverse impact on public health and
safety. Nothing in this subsection (e)(11)(B) prevents the City from
changing the occupancy code of a space that was uninhabitable space
15 O 1113
or that was only permitted for nonresidential use and was subsequently
converted for residential use in accordance with this section.
(f) Specific ADU Requirements. The following requirements apply only to ADUs that
require zoning compliance review under subsection (d)(2) above.
(1) Maximum Size.
(A) The maximum size of a detached or attached ADU subject to this
subsection (f) is 850 square feet for a studio or one-bedroom unit and
1,000 square feet for a unit with two or more bedrooms.
(B) A new attached ADU that is created on a lot with an existing primary
dwelling is limited in area to 50 percent of the floor area of the existing
primary dwelling or the limits in (f)(1)(A) above, whichever is less.
(C) Application of other development standards in this subsection (f), such
as lot coverage, may further limit the size of an ADU. However, no
application of the percentage-based size limit in subsection (f)(1)(B)
above or the lot-coverage limit in subsection (f)(3) below may require
the ADU to be less than 800 square feet.
(2) Setbacks.
(A) Subject to subsection (f)(2)(B) below, an ADU subject to this subsection
(f) must conform to a 30-foot front yard setback.
(B) If the front yard setback is the only location on the lot where an ADU
may be lawfully constructed, then the ADU may encroach into the
required front yard setback as necessary to enable the construction of
an 800 square foot unit.
(C) An ADU subject to this subsection (f) must conform to 4-foot side and
rear-yard setbacks.
(D) No setback is required for an ADU that is subject to this subsection (f)
if the ADU is constructed in the same location and to the same
dimensions as an existing structure.
(3) Lot Coverage. A new attached or detached ADU under this subsection (f) is
subject to a lot-coverage limit of 0.35, subject to subsection (f)(1)(C) above.
(4) Passageway. No pathway that is unobstructed clear to the sky and extends
from a street to one entrance of the ADU is required.
(5) Parking.
(A) One off-street parking space measuring at least 9 feet wide by 19 feet
long is required for each ADU on the property where the ADU is located.
16 O 1113
The required parking space may be provided in a garage or carport or
on a driveway or within a paved setback area and may be configured
as tandem parking. If the owner elects to provide the parking space in
a garage or carport, the garage or carport is subject to any applicable
zoning standards of Title 9 of this Code.
(B) The new attached or detached ADU and primary dwelling must use the
same driveway apron to access the street, unless a separate driveway
apron for the new ADU is required by the fire authority.
(C) Exceptions. No parking under subsection (f)(5)(A) is required in the
following situations:
(i) The ADU is located within one-half mile walking distance of a
public transit stop, as defined in subsection (c)(8) above.
(ii) The ADU is located within the Los Rios Historical Residential
District or the Mission Residential Zoning District.
(iii) The ADU is integrated into a proposed or existing primary
residence or garage or other accessory structure under
subsection (d)(1)(A).
(iv) When on-street parking permits are required but not offered to
the occupant of the ADU.
(v) When there is an established car share vehicle stop located
within one block of the ADU.
(vi) When the permit application to create an ADU is submitted with
an application to create a new single-family or new multifamily
dwelling on the same lot, provided that the ADU or the lot
satisfies any other criteria in subsections (f)(5)(C)(i) through
(f)(5)(C)(v) above.
(D) No Replacement. When a garage, carport, or other covered-parking
structure is demolished in conjunction with the construction of an ADU
or if a garage, carport or other covered-parking structure is converted
to an ADU, those off-street parking spaces are not required to be
replaced.
(6) Architectural Requirements.
(A) The exterior sides of the ADU shall be covered with wood, stucco,
masonry, or other material of the same appearance and durability.
Metal siding shall not be permitted.
(B) The roof material of the ADU shall be wood shingle or shake, slate, tile,
or other material of the same appearance and durability.
17 O 1113
(C) The roof eaves and gables of the ADU shall be no less than 12 inches,
as measured from the vertical side of the unit.
(D) If the ADU would be visible from an adjoining public right-of-way, the
materials and colors of the exterior walls, roof, windows and doors of
the ADU must match the appearance and architectural design of those
of the primary dwelling.
(E) If the ADU would be visible from an adjoining public right-of-way, the
roof slope of the ADU must match the dominant roof slope of the
primary dwelling, if feasible. The dominant roof slope is the slope of the
largest portion of the roof.
(F) Exterior lighting of the ADU must be limited to down-lights or as
otherwise required by the building or fire code.
(G) The ADU must have an independent exterior entrance, apart from that
of the primary dwelling.
(H) Fencing, landscaping, or privacy glass may be used to provided
screening and prevent a direct line of sight to contiguous residential
property.
(7) Historical Protections. The architectural treatment of a new attached or
detached ADU to be constructed on a lot that has an identified historical
resource listed on the California Register of Historic Resources must comply
with all applicable ministerial requirements imposed by the Secretary of the
Interior.
(8) Septic System. If the ADU will connect to an onsite water-treatment system,
the owner must include with the application a percolation test completed within
the last five years or, if the percolation test has been recertified, within the last
ten years.
(9) Ridgeline Protection. No ADU, or grading related to construction of an ADU,
shall be permitted within 200 feet (horizontal) of a General Plan designated
ridgeline, or as designated on a final City subdivision.
(g) Fees. The following fees apply to all ADUs and JADUs approved by the City under
this section.
(1) Impact Fees.
(A) No impact fee is required for an ADU that is less than 750 square feet
in habitable floor area.
(B) Any impact fee that is required for an ADU that is 750 square feet or
larger in habitable floor area must be charged proportionately in
relation to the habitable floor area of the primary dwelling unit. (E.g.,
18 O 1113
the habitable floor area of the primary dwelling, divided by the
habitable floor area of the ADU, times the typical fee amount charged
for a new dwelling.) “Impact fee” here does not include any connection
fee or capacity charge for water or sewer service.
(2) Utility Connections and Fees. ADUs are subject to the utility connection

(h) Nonconforming Zoning Code Conditions, Building Code Violations, and
Unpermitted Structures.
(1) Generally. The City will not deny an ADU or JADU application due to a
nonconforming zoning condition, building code violation, or unpermitted
structure on the lot that does not present a threat to the public health and safety
and that is not affected by the construction of the ADU or JADU.

(A) Permit to Legalize. As required by state law, the City may not deny a

grounds:
(i) The ADU violates applicable building standards; or
(ii) The ADU does not comply with state ADU law (Government
Code Section 65852.2) or this ADU ordinance (section 9-
3.501.1).
(B) Exceptions.
(i) Notwithstanding subsection (h)(2)(A), the City may deny a permit
to legalize an existing but unpermitted ADU that was constructed
before January 1, 2018, if the City makes a finding that correcting
a violation is necessary to protect the health and safety of the
public or of occupants of the structure.
(ii) Subsection (h)(2)(A) above does not apply to a building that is
deemed to be substandard in accordance with California Health
and Safety Code section 17920.3.
(i) Nonconforming ADUs and Discretionary Approval. Any proposed ADU or JADU
that does not conform to the objective standards set forth in subsections (a) through
(h) of this section may be allowed by the City with a zone variance, in accordance
with Section 9-2.351 of this Code.
