2030 VISION STATEMENT:
This staff report supports Mission Statement, Goal No. 3 to promote economic
development by updating zoning and development code in preparation for future
development, and to preserve and protect our community and its exceptional quality of
life through thoughtful planning.
BACKGROUND:
On January 25, 2022, the City Council adopted Urgency Ordinance No. 336-U,
establishing objective standards for the regulation of lot splits and new units developed
under Senate Bill 9 (SB9). At the meeting, the City Council directed staff to process a
regular SB9 Ordinance and directed staff to update the City’s regulations on accessory
dwelling units (ADUs) and junior accessory dwelling units (JADUs). The City Council
provided comments to be reviewed by staff and to be incorporated in the proposed city
standards, if permissible by state law.
On March 3, 2022, the Planning Commission conducted a Noticed Public Hearing and
voted unanimously 4-0 adopting a Resolution recommending that the City Council adopt
an Ordinance establishing standards for SB 9 lot splits and developments and
recommending that the City Council adopt an Ordinance updating the city’s ADU/JADU
B.1
Packet Pg. 4
regulations. At the meeting, the Planning Commission reviewed the City Council’s
comments and made additional recommendations to be included to the SB9 and
ADU/JADU standards.
On March 22, 2022, the City Council conducted a Noticed Public Hearing and voted
unanimously 5-0 to continue the Public Hearing to a date uncertain and direct staff to
conduct a joint City Council and Planning Commission workshop to further review and
discuss the State Legislation requirements and provide input on the city’s proposed
objective standard for SB9 and ADU/JADU developments.
The SB 9 and ADU/JADU laws are related as they both result in additional residential
density and create additional development options on single-family residential zoned
properties. Both legislations allow cities to establish objective standards as long as they
do not conflict with state law. Consequently, the workshop will focus on the legislation
requirements and the city’s proposed objective standards to govern future SB 9 and
ADU/JADU projects.
DISCUSSION:
ADU/JADU Ordinance
State law allows the development of ADUs and JADUs in residential and mixed-use
zones. The City’s current ADU ordinance was adopted in 2017. ADU and JADU laws
have been revised substantially in the last 5 years. Consequently, the City’s ADU and
JADU regulations must be updated in order to comply with state law.
The majority of ADU/JADU law is set by state law and does not allow for any flexibility at
the local level. There are, however, a few issues that the City can regulate, and
consequently staff is seeking direction on these issues. The issues are as follows:
1. Size: The City an establish minimum and maximum sizes for ADUs. The
minimum size cannot be smaller than an “efficiency unit,” which is 220 square
feet. If the city wants to be as restrictive as possible, the City can set the
following maximum size requirements:
Detached ADU Studio/1-bedroom: 850 sf 2+
bedrooms: 1000 sf
Attached ADU Studio/1-bedroom: 850 sf, or
50% of floor are in primary
unit, whichever is smaller
(but no less than 800 sf) 2+
bedrooms: 1000 sf, or 50%
of floor are in primary unit,
whichever is smaller (but no
less than 800 sf)
However, if the City would like to be less restrictive, these maximum sizes can be
B.1
Packet Pg. 5
increased. A standard maximum size in less restrictive cities is 1,200 sf. Size
limitations will not apply to ADUs created by converting space in an existing
structure.
2. Height: If the City wants to be as restrictive as possible, it can limit ADUs
to a maximum of 16 feet in height. However, the City may allow a less restrictive
height limit. Furthermore, the City may restrict new ADU construction to ground-
level only, or may allow ADUs to be added on as second stories - for example,
above detached garages. Height limitations will not apply to ADUs created by
converting space in an existing structure.
3. Water, Sewer, and Septic: Requirements for water, sewer, and septic are
included in Section 18.69.050(e)(8)-(9) of the proposed ADU ordinance. These
requirements could be revised if desired.
4. Design Standards: The City may impose objective design and
architectural standards on ADUs. In the absence of ADU-specific standards, the
City’s general design standards would apply. Staff are recommending the
following standards:
- The architectural design and detailing, roof material, exterior color, and finish
materials of an accessory dwelling unit or junior accessory dwelling unit shall be
the same as those of the primary dwelling.
- If a manufactured home is used as an accessory dwelling unit, it shall comply
with the following design requirements:
a. It shall comply with the design standard above, except that if
materials matching the primary dwelling are not commercially available for a
manufactured home, then finish materials shall be the same color as the finish
materials on the primary dwelling;
b. The roof shall have a minimum 16-inch overhand and shall have a
minimum pitch of not less than two inches vertical rise for each 12 inches of
horizontal run; and
c. Mechanical equipment associated with the manufactured home
shall be located so as to not be visible from a public street or adjoining property.
5. Additional Development Standards: Staff would like direction on any
other development standards that the Council or Commission would like to see in
the ADU/JADU ordinance. These could include, for example, a minimum
required distance between detached structures on a single parcel, a requirement
to replace trees that are removed due to construction of a new unit, etc.
SB 9 Ordinance
Senate Bill No. 9 (SB 9) became effective on January 1, 2022. SB 9 has two primary
effects on City land use regulations. First, it requires cities to permit up to two primary
B.1
Packet Pg. 6
residences on each parcel in single-family residential zones, where previously only one
primary residence would be allowed. When combined with ADUs/JADUs, this means
that a parcel in a single-family residential zone could have up to 4 dwelling units, if it
was not created through an SB 9 lot split.
Second, SB 9 requires cities to permit owners of single-family residential lots to split
their lots in half and create two separate smaller parcels, even if the resulting lots are
smaller than the minimum lot size otherwise allowed. New lots resulting from an SB 9
lot split may only have up to two units on them, inclusive of ADUs and JADUs.
As with ADUs/JADUs, many of the regulations under SB 9 are set by state law and
cannot be changed by cities. However, the City does have some authority to set
objective zoning, subdivision, and design standards that do not conflict with state law.
Staff is seeking direction regarding the following issues:
1. Size: Under SB 9, a lot may have either 1 or 2 primary units on it. If it has
two units, they could be detached from one another or attached (i.e. a duplex).
The city can set size requirements for these units, but cannot make the size
smaller than 800 square feet.
There is one more factor to consider. Some of the units will be on normal-sized
lots. However, other units could be built on substandard-sized lots that result
from SB 9 lot splits. The City may want to have different size standards
depending on whether the unit is on a standard parcel or a lot-split parcel.
Here is one possible regulation:
(a) The first primary unit on a lot will have no maximum size
requirement, but will only be subject to setback, maximum lot
coverage, and other development standards applicable to the lot.
(b) The second primary unit on a lot will be limited to 800 sf.
(c) A new construction duplex (2 attached units) will be limited to 1,200
sf per unit.
Another option would be to create an (a)(1) for standard lots and an (a)(2) for lot-
split lots, as follows:
(a)(1) Standard-Sized Parcel: The first primary unit on a lot will have no
maximum size requirement, but will only be subject to setback,
maximum lot coverage, and other development standards
applicable to the lot.
(a)(2) Substandard-Sized Parcel: The first primary unit on a lot resulting
from an SB 9 lot split will be limited to 1,200 sf.
The numbers stated above are just examples and could be changed, but cannot
be less than 800 sf.
B.1
Packet Pg. 7
2. Height: Does City want to impose height restrictions on the first and/or
second primary unit on a parcel?
3. Notice: Does City want to give adjacent property owners notice that an
application for an urban lot split or second primary unit has been submitted?
4. Water, Sewer, and Septic: Staff is proposing requirements for water,
sewer, and septic that are similar to those for ADUs. See Section 18.65.040(G)
of the proposed SB 9 ordinance. These requirements could be revised if desired.
5. Additional Development Standards: Staff would like direction on any
other development standards that the Council or Commission would like to see in
the SB 9 ordinance. These could include, for example, a minimum required
distance between detached structures on a single parcel, a requirement to
replace trees that are removed due to construction of a new unit, etc.
6. Shape of Parcel Resulting from Lot Split: Does the Council or
Commission have a preference for side-by-side lots or flag lots or no preference?
If there is a preference, the City can impose requirements to impose that
preference - for example, minimum frontage requirements, minimum lot width,
prohibition of flag lots, etc.
Changes to Previously Proposed Regulations
Staff would also like to note a few regulations that were previously proposed but are no
longer being proposed in light of new information distributed by the Department of
Housing and Community Development and other analysis.
First, it was previously proposed to require the development of two units on a vacant
parcel created by an SB 9 lot split (i.e. the owner would not be allowed to build just one
unit on a vacant parcel created by an SB 9 lot split).
Second, it was previously proposed to require that second units and two-unit
developments created under SB 9, if rented, could only be rented to lower-income
households at an affordable rent for 55 years, which would be enforced through a
covenant recorded on the property.
Third, it was previously proposed that JADUs would not be allowed on parcels with two
primary units.
These regulations are no longer being proposed by staff.

determines that the addition of a new unit or units would
result in a violation of the requirements of the California
Plumbing Code, the requirements of the Santa Ana
Regional Water Quality Control Board, and/or other
objective City sewer or septic system requirements, then the
City shall impose conditions of approval on the
development that are necessary to ensure compliance with
such requirements.
(B) If a parcel relies on an onsite wastewater treatment system,
and a proposed unit would be located on the only part of
the parcel that could accommodate a new onsite

disconnected from the onsite wastewater treatment system and
connected to the sewer system as a condition of approval of the
development. If such disconnection and connection is not

official, or designee, shall consider whether such circumstances
are grounds for denial of the proposed project pursuant to Section
18.65.020.C.
3. A second unit, and both of the units in a two-unit development,
shall each have a separate connection to the main water service
line in the street and the applicant shall submit plans for such

on site for each tree removed. The proposed project site shall have a
minimum of one tree per unit.
J. Additional Development Standards. Except as provided in subsections A
through I, second units, and each unit of a two-unit development, shall
comply with all development standards that would be applicable to a
primary dwelling unit on the same parcel.
K. Limitation on Enforcement of Development Standards. With the
exceptions of the setback requirements in subsection D and the
requirement to comply with all building codes, the City shall not enforce
any development standard to the extent that it would have the effect of
physically precluding the construction of a second unit or two-unit
development on a parcel, or would physically preclude either the second
unit or both units of a two-unit development from being at least 800
square feet in floor area.

ORDINANCE NO.336-U
AN URGENCY ORDINANCE OF THE CITY COUNCIL OF THE CITY
OF GRAND TERRACE ESTABLISHING REGULATIONS FOR URBAN
LOT SPLITS AND TWO-UNIT DEVELOPMENTS IN ACCORDANCE
WITH SENATE BILL 9
WHEREAS, on September 16, 2021, the Governor signed into law Senate Bill 9 (SB 9).
This bill requires the ministerial approval of two dwelling units per parcel in single-family
residential zones, where previously only one primary dwelling unit would have been permitted,
and requires ministerial approval of lot splits in single-family residential zones and allows two
units to be built on each resulting parcel; and
WHEREAS,SB 9 took effect on January 1,2022,and it is therefore necessary for the City
to establish objective standards regarding housing developments and lot splits authorized by SB 9
as soon as possible; and
WHEREAS,the City Council desires to establish objective standards governing units and
lots splits authorized by SB 9 to preserve the City's character and quality of life as characterized
by the City's General Plan; and
WHEREAS,pursuant to Government Code Section 36937,subdivision(b), any ordinance
for the immediate preservation of the public peace, health, or safety, containing a declaration of
the facts constituting the urgency, that is passed by a four-fifths (4/5) vote of the City Council,
shall take effect immediately upon its adoption; and
WHEREAS,the City Council seeks and intends to protect the health, safety, and welfare
of the residents of the City of Grand Terrace by establishing regulations for urban lot splits and
two-unit developments in single family residential zones, as further described herein.
NOW THEREFORE, the City Council of the City of Grand Terrace does hereby ordain
as follows:
SECTION 1. Recitals. The above recitals are incorporated by reference.
SECTION 2. Urgency Findings.
A. SB 9 requires the ministerial approval of two dwelling units per parcel in single-
family residential zones, where previously only one primary dwelling unit would have been
permitted, in addition to accessory dwelling units and junior accessory dwelling units, in some
cases.
B. Additionally, SB 9 requires ministerial approval of lot splits in single-family
residential zones and allows two units to be built on each resulting parcel.
C. This bill has the potential to dramatically increase the density and population of
single-family zones, potentially placing a strain on public resources and the infrastructure that
serves these zoning districts.

D. Moreover, SB 9 continues a pattern of state action that deprives cities of control
over issues of fundamental local concern and traditional local control, namely, the character and
quality of residential neighborhoods and the ability to control and plan for the uses of land in the
City.
E. SB 9 took effect on January 1, 2022, and it is therefore necessary for the City to
establish objective standards regarding the housing developments and lot splits that the City will
now be required to permit, and to ensure that such regulations take effect as soon as possible, so
as to protect and provide for the welfare of the local community.
SECTION 3. CEQA. The City Council finds and determines that these ordinance
amendments are not a "project' for purposes of California Environmental Quality Act (CEQA)
pursuant to Government Code Sections 65852.216) and 66411.7(n), and therefore do not require
any environmental review under CEQA.
SECTION 4. Section 17.04.040, subjection H, of the Grand Terrace Municipal Code is
hereby amended as follows with the remainder of Section 17.04.040 remaining unchanged

units;
