Connection Therewith
BACKGROUND AND DISCUSSION
New building standards adopted by the State will take effect on January 1, 2023. The
State of California Health and Safety Code requires all jurisdictions to enforce the most
recent editions of these various building standards. Although the State requires the
enforcement of certain standards, it allows the City to amend these standards in order to
address local concerns. The State, however, does limit the City's ability to amend the
prescribed building standards to amendments that are stricter than State standards and
are reasonably necessary for reasons relating to local climate, geology and topography.
The proposed Ordinance (attached), which would take effect on January 1, 2023,
concurrently with the new State standards, includes adoption of the State standards,
along with amendments to specific building code sections dealing with administration and
fees as well as changes to the building standards to improve public safety with respect

especially to earthquakes and fire hazards. The proposed amendments in the Ordinance
were developed and recommended by local building officials and engineers in conjunction
with the Structural Engineers Association of California (SEAC). SEAC, the City of Los
Angeles, and the cities of Ventura County as a unified consortium agreed to recommend
adoption of these additional amendments (which exceed the 2022 California Building
Standards Codes) given unique climatic, geological, and topographical conditions that
impact our local environment pursuant to Section 17958.5 of the Health and Safety Code.
The proposed amendments to the 2022 California Building Code and Residential Code
are essentially the same as those made to the 2019 codes by City Ordinance No. 474,
and include stricter standards for foundation design, swimming pools, expansive soil
conditions, fire-resistive construction including roof materials, unreinforced footings, and
engineered truss systems.
Because of the proposed amendments, State law requires that the Council direct staff to
advertise a public hearing to be held at least fifteen (15) days prior to consideration of
second reading of the ordinance. Additionally, the City is required to send the
amendments to the State. The City Attorney has reviewed and approved the form of the
Ordinance.
PRIMARY CHANGES
Fire Hazard Severity Zones:
Existing Section 15.08.060 Fire Hazard Zone Requirements of the Moorpark Municipal
Code for construction within a Fire Hazard Severity Zone are deleted as Chapter 7A of
the 2022 edition of the California Building Code and Section R337 of the 2022 edition of
the California Residential Code have been added to address construction in the High Fire
Hazard Severity Zones (HFHSZ) and is therefore an unnecessary redundancy within the
Moorpark Municipal Code. Further, the geographical areas of Moorpark within these
zones are mapped on Cal Fire’s Fire and Resource Assessment Program (FRAP) Very
High Fire Hazard Severity Zone Map.
Swimming Pool Enclosures and Barriers:
In the previous 2019 code cycle the State Building codes did not adopt the pool
enclosures provision requiring all residences with pools to maintain a 60-inch-high
enclosure around the pool.
These topics were previously included in the 2016 State building codes but were removed
by the International Code Council in 2019 and placed in the International Swimming Pool
and Spa Code. Rather than reference or incorporate the entire International Swimming
Pool and Spa Code, staff has elected to continue to include two sections within the City’s
local code referencing pool enclosures around the pool.
These two sections referencing swimming pool enclosures are to be maintained in the
Moorpark Municipal Code and renumbered as Sections 15.08.050 and 15.08.060.

ENVIRONMENTAL DETERMINATION
This Ordinance is exempt from the provisions of the California Environmental Quality Act
(CEQA) pursuant to Section 15061(b)(3) of the California Code of Regulations (CEQA
Guidelines) by the general rule that CEQA only applies to “projects” that may have a
significant effect on the environment. The proposed Ordinance would amend the
Municipal Code related to building standards necessary to protect health and safety. In
this case, there is no possibility that the proposed Ordinance would have a significant
impact on the environment.
FISCAL IMPACT
There are no direct fiscal impacts associated with this request.
COUNCIL GOAL COMPLIANCE
This action does not support a current strategic directive.
STAFF RECOMMENDATION (ROLL CALL VOTE REQUIRED)
Staff recommends that the City Council:
1. Open the public hearing, receive public testimony, and close the public hearing;
and
2. Waive full reading and declare Ordinance No. 508 read for the second time and
adopted as read; and
3. Direct staff to send the changes to the Code to the California Building Standards
Commission.

NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF MOORPARK DOES
ORDAIN AS FOLLOWS:
SECTION 1. ENVIRONMENTAL DETERMINATION: The City Council has determined that
this Ordinance amending Title 15 of the Moorpark Municipal Code is exempt from the provisions of
the California Environmental Quality Act (CEQA) pursuant to Section 15061(b)(3) of the California
Code of Regulations (CEQA Guidelines) based on the general rule that CEQA only applies to
"projects" that may have a significant effect on the environment. This Ordinance would amend the
Municipal Code related to building standards necessary to protect health and safety. In this case, it
can be seen with certainty that there is no possibility that this Ordinance may have a significant
impact on the environment. Based on the foregoing, the City Council, based on its own independent
judgment, finds that the adoption of this Ordinance is exempt from CEQA.
SECTION 2. AMENDMENTS NECESSARY. Pursuant to Section 17958.7 of the Health
and Safety Code of the State of California, the City Council of the City of Moorpark hereby finds
that each amendment to building standards contained in the 2022 Editions of the California
Building Code and California Residential Code made by this Ordinance is reasonably necessary
due to local climatic, geological and topographical conditions as follows:
Local Climatic Conditions - The local climate is characterized by periods of high
temperatures accompanied by low humidity and high winds each year. These conditions could
create an environment in which the fire department may have great difficulty in controlling fires
occurring in hillside brush areas as well as structures not having built-in fire protection. The City
also experiences periods of intense rainfall, which create the need for special drainage
precautions.
Local Geological Conditions - The Moorpark/Ventura County region is a populated area
having buildings constructed over and near fault systems capable of producing major
earthquakes. The City is located in an area with expansive soils and areas subject to flood hazards
including hillsides that are subject to mud flows and unstable soils. These conditions require that
special foundation considerations and soils analysis requirements must be in place to provide a
reasonable degree of structural integrity for buildings to prevent injury to building occupants,
neighbors, and persons using public property.
Local Topographical Conditions - The City contains and is located near hillside brush
areas, so special fire resistive requirements are required in order to reduce fire damage and fire
spread during periods of high temperatures and low humidity. This requires special construction
elements for structures in the City to reduce the threat of fire damage and fire spread during
periods of high temperatures and low humidity.
240
Ordinance No. 508
Page 3
These local climatic, geological and topographical conditions require specific and greater
protection than is afforded by the 2022 Editions of the California Building Code and California
Residential Code. Specific findings for each of these amendments are set forth in Exhibit A
attached hereto and incorporated by reference herein.
SECTION 3. Chapters 15.04 (Administrative Provisions), 15.08 (Building Code),15.10
(California Green Building Standards Code), 15.12 (Electrical Code), 15.14 (Plumbing Code),
15.16 (Mechanical Code), 15.18 (Housing Code), 15.20 (California Energy Code), and 15.22
(California Residential Code) of Title 15 (Buildings and Construction) of the Moorpark Municipal
Code are repealed and replaced in their entirety as shown in Exhibit B attached hereto and
incorporated by reference herein provided, however, that such repeal shall not affect or excuse
any violation of any provision of the Moorpark Municipal Code occurring prior to the effective date
of this Ordinance.
SECTION 4. If any section, subsection, sentence, clause, phrase, part or portion of this
Ordinance or any of the Codes adopted herein is for any reason held to be invalid or unconstitutional
by any court of competent jurisdiction, such decision shall not affect the validity of the remaining
portions of this Ordinance or such Codes. The City Council declares that it would have adopted this
Ordinance and such Codes, and each section, subsection, sentence, clause, phrase, part or portion
thereof, irrespective of the fact that any one or more section, subsections, sentences, clauses,
phrases, parts or portions be declared invalid or unconstitutional.
SECTION 5. This Ordinance shall become effective on January 1, 2023.
SECTION 6. The City Clerk shall certify to the passage and adoption of this ordinance; shall
enter the same in the book of original ordinances of said City; shall make a written record of the
passage and adoption thereof in the minutes of the proceedings of the City Council at which the
same is passed and adopted; and shall publish notice of adoption in the manner required by law.

EXHIBIT A
Reasons for Amendments to California Building Code and California Residential Code
and Findings pursuant to Section 17958.7 of the Health and Safety Code
Pursuant to Section 17958.7 of the Health and Safety Code of the State of California, the City
Council of the City of Moorpark hereby finds that each amendment to the 2022 Editions of the
California Building Code and California Residential Code made by this Ordinance is reasonably
necessary due to local climatic, geological and topographical conditions. These local climatic,
geological and topographical conditions require specific and greater protection than is afforded by
the 2022 Editions of the California Building Code and California Residential Code as follows:
15.08.030 Foundation design.
Reason for Amendment:
Section 15.08.030 of the Moorpark Municipal Code adds language to Section 1808.6.5 of the
2022 California Building Code to provide specific requirements to reduce expansive soil, shrink
and swell effects on structures constructed on grade in those areas of the City with these unique
soils.
Findings:
Local Geological Conditions - The Moorpark/Ventura County region is a populated area having
buildings constructed over and near fault systems capable of producing major earthquakes. The
City is located in an area with expansive soils and areas subject to flood hazards including hillsides
that are subject to mud flows and unstable soils. These conditions require that special foundation
considerations and soils analysis requirements must be in place to provide a reasonable degree
of structural integrity for buildings to prevent injury to building occupants, neighbors, and persons
using public property. These factors require specific and greater protection than is afforded by
California Building Codes.
15.08.040 Table 1809.7 amended.
Reason for Amendment:
Section 15.08.040 of the Moorpark Municipal Code replaces Table 1809.7 of the 2022 California
Building Code in its entirety to provide specific requirements to reduce expansive soil, shrink and
swell effects on structures constructed on grade in those areas of the City with these unique soils.
Findings:
Local Geological Conditions - The Moorpark/Ventura County region is a populated area having
buildings constructed over and near fault systems capable of producing major earthquakes. The
City is located in an area with expansive soils and areas subject to flood hazards including hillsides
that are subject to mud flows and unstable soils. These conditions require that special foundation

15.08.050 Swimming pool enclosures and safety devices.
Reason for Amendment:
Section 15.08.050 of the Moorpark Municipal Code adds a definition of Barrier and Swimming
Pools to Section 202 of the 2022 California Building Code.
Findings:
The local climate is characterized by periods of high temperatures accompanied by low humidity
and high winds each year. The warm climate encourages the proliferation of swimming pool
construction which makes modifications to the California Building Code relating to swimming pools
desirable to adequately protect small children from drowning hazards.
15.08.060 Swimming pool barrier.
Section 15.08.060 of the Moorpark Municipal Code amends Section 3109.1, and adds new
Section 3109.3 through 3109.3.3 to the 2022 California Building Code. The barrier fencing
requirements were removed from the 2022 California Building Code. This barrier fence protects
children from accidently being able to access properties with pools.
Findings:
The local climate is characterized by periods of high temperatures accompanied by low humidity
and high winds each year. The warm climate encourages the proliferation of swimming pool
construction which makes modifications to the California Building Code relating to swimming pools
desirable to adequately protect small children from drowning hazards.
15.08.070 Swimming pools.
Reason for Amendment:
Section 15.08.070 of the Moorpark Municipal Code adds Section 3109.7 to the 2019 California
Building Code to provide specific requirements to reduce expansive soil, shrink and swell effects
on swimming pools in those areas of the City with these unique soils.
Findings:
Local Geological Conditions - The Moorpark/Ventura County region is a populated area having
buildings constructed over and near fault systems capable of producing major earthquakes. The
City is located in an area with expansive soils and areas subject to flood hazards including hillsides
that are subject to mud flows and unstable soils. These conditions require that special foundation
considerations and soils analysis requirements must be in place to provide a reasonable degree
of structural integrity for buildings to prevent injury to building occupants, neighbors, and persons
using public property. These factors require specific and greater protection than is afforded by
California Building Codes.

15.22.030 Footings.
Reason for Amendment:
Section 15.22.030 of the Moorpark Municipal Code amends Sections R403.1.2, R403.1.3, and
R403.1.5 of the 2022 California Residential Code to reduce potential problems that can result
from under-reinforced footings and addresses the under- performance of plain concrete or under-
reinforced concrete during a seismic event.
Findings:
Local Geological Conditions - The Moorpark/Ventura County region is a populated area having
buildings constructed over and near fault systems capable of producing major earthquakes. The
City is located in an area with expansive soils and areas subject to flood hazards including hillsides
that are subject to mud flows and unstable soils. These conditions require that special foundation
considerations and soils analysis requirements must be in place to provide a reasonable degree
of structural integrity for buildings to prevent injury to building occupants, neighbors, and persons
using public property. These factors require specific and greater protection than is afforded by
California Building Codes.
15.22.040 TABLES R403.1(1), (2), and (3) Amended.
Reason for Amendment:
Section 15.22.040 of the Moorpark Municipal Code amends Tables R403.1(1), (2), and (3) of the
2022 California Residential Code to reduce potential problems that can result from under-
reinforced footings and addresses the under-performance of plain concrete or under- reinforced
concrete during a seismic event.
Findings:

buildings constructed over and near fault systems capable of producing major earthquakes. The
City is located in an area with expansive soils and areas subject to flood hazards including hillsides
that are subject to mud flows and unstable soils. These conditions require that special foundation
considerations and soils analysis requirements must be in place to provide a reasonable degree
of structural integrity for buildings to prevent injury to building occupants, neighbors, and persons
using public property. These factors require specific and greater protection than is afforded by
California Building Codes.
15.22.050 Foundation Design.
Reason for Amendment:
Section 15.22.050 of the Moorpark Municipal Code amends Section R403.1.8 of the 2022
California Residential Code to provide specific requirements to reduce expansive soil, shrink swell
effects on structures constructed on grade in those areas of the City with these unique soils. This
section also provides special criteria for storm water drainage on lots to mitigate the effects of
runoff associated with intense rainfall, for structures located in flat land developments as well as
hillside areas.

Findings:
Local Geological Conditions - The Moorpark/Ventura County region is a populated area having
buildings constructed over and near fault systems capable of producing major earthquakes. The
City is located in an area with expansive soils and areas subject to flood hazards including hillsides
that are subject to mud flows and unstable soils. These conditions require that special foundation
considerations and soils analysis requirements must be in place to provide a reasonable degree
of structural integrity for buildings to prevent injury to building occupants, neighbors, and persons
using public property. These factors require specific and greater protection than is afforded by
California Building Codes.
15.22.060 Lateral Support.
Reason for Amendment:
Section 15.22.060 of the Moorpark Municipal Code amends Section R802.8 of the 2022 California
Residential Code to reduce potential problems that can result from poorly designed truss systems
and connections.
Findings:
Local Geological Conditions - The Moorpark/Ventura County region is a populated area having
buildings constructed over and near fault systems capable of producing major earthquakes. The

protection than is afforded by California Building Codes.
15.22.070 Wood Truss Design.
Reason for Amendment:
Section 15.22.070 of the Moorpark Municipal Code amends Section R802.10.2 of the 2022
California Residential Code to reduce potential problems that can result from poorly designed
truss systems and connections.
Findings:
Local Geological Conditions - The Moorpark/Ventura County region is a populated area having
buildings constructed over and near fault systems capable of producing major earthquakes. The
City is located in an area with expansive soils and areas subject to flood hazards including hillsides
that are subject to mud flows and unstable soils. These factors require specific and greater
protection than is afforded by California Building Codes.
15.22.080 Roofing.
Reason for Amendment:
Section 15.22.080 of the Moorpark Municipal Code amends Section R902.1 of the 2022 California
Residential Code to not permit wooden shake or shingle roofs, treated or untreated. The City is
located near hillside brush areas, so special fire resistive requirements are required in order to reduce
fire damage and fire spread during periods of high temperatures and low humidity. This amendment
requires special construction elements for structures near and in the City to reduce the threat of fire
damage and fire spread during periods of high temperatures and low humidity.
245
Ordinance No. 508

Footnotes to Table R403.1
1. Pre-moistening is required where specified in Table R403.1 in order to achieve maximum
and uniform expansion of the soil prior to construction and thus limit structural distress
caused by uneven expansion and shrinkage. Other systems, which do not include pre-
moistening, may be approved by the building official, when such alternatives are shown to
provide equivalent safeguards against the adverse effects of expansive soil.
2. Under-floor access crawl holes shall be provided with curbs extending not less than 6 inches
above adjacent grade to prevent surface water from entering the foundation area.
3. Reinforcement for continuous foundations shall be placed not less than 3 inches above the
bottom of the footing and not less than 3 inches below the top of the stem.
4. Slab reinforcement shall be placed at mid-depth and continue to within 2 inches of the
exterior face of the exterior face of the exterior footing walls.
5. Moisture content of soils shall be maintained until foundations and piers are poured and a
vapor barrier is installed. Test shall be taken within 24 hours of each slab pour.
6. Crawl spaces under raised floors need not be pre-moistened except under interior footings.
Interior footings which are not enclosed by a continuous perimeter foundation system or
equivalent concrete or masonry moisture barrier shall be designed and constructed as
specified for perimeter footings in Table R403.1.
7. A grade beam not less than 12 inches by 12 inches in cross-sectional area, reinforced as
specified for continuous foundations in Table R403.1, shall be provided at garage door
openings.
8. Foundation stem walls which exceed a height of three (3) times the stem thickness above
lowest adjacent grade shall be reinforced in accordance with Sections 18 and 19 in the
California Building Code, or as required by engineering design, whichever is more restrictive.
9. Footing widths may be reduced upon submittal of calculations by a registered civil or
structural engineer or licensed architect, but shall be a minimum of 12 inches for one- and
two-story structures and 15 inches for three-story structures.
10. Bent reinforcing bar between exterior footing and slab shall be omitted when floor is designed
as an independent, "floating" slab.
11. Fireplace footings shall be reinforced with a horizontal grid located 3 inches above the bottom
of the footing and consisting of not less than #4 bars at 12 inches on center each way.
Vertical chimney reinforcing bars shall be hooked under the grid.
12. Underground utility conduits shall be installed prior to foundation inspection and shall extend
beyond the foundation.

15.22.050 Foundation design.
The first paragraph of Section R403.1.8 of the California Residential Code is amended to read as
follows:
R403.1.8 Foundations on expansive soils. Foundations and floor slabs for buildings located
on expansive soils shall be designed in accordance with Section 1808.6 of the California
Building Code provided, however, that when buildings are located on expansive soil having
an expansion index greater than 50, gutters, downspouts, piping and/or other non-erosive
devices shall be provided to collect and conduct rainwater to pervious areas such as yards,
open channels or vegetated areas. Routing rooftop runoff via yard drains to the roadway or
the storm water conveyance system shall not be permitted. [Note: the remainder of Section
R403.1.8 remains unchanged.]
15.22.060 Lateral support.
Section R802.8 of the California Residential Code is amended to read as follows:
R802.8 Lateral Support. Roof framing members and ceiling joists having a depth-to-
thickness ratio exceeding two (2) to one (1) based on nominal dimensions shall be
provided with lateral support at points of bearing to prevent rotation. For roof rafters with
ceiling joists attached per Table R602.3(1), the depth-thickness ratio for the total assembly
shall be determined using the combined thickness of the rafter plus the attached ceiling
joist.
15.22.070 Wood truss design.
Section R802.10.2 of the California Residential Code is amended to read as follows:
R802.10.2 Design. Wood trusses shall be designed in accordance with accepted
engineering practice. The design and manufacture of metal-plate- connected wood trusses
shall comply with American National Standards Institute/Truss Plate Institute (ANSI/TPI)
1. The truss design drawings shall be prepared by a registered professional.
15.22.080 Roofing.
Section R902.1 of the California Residential Code is amended to read as follows:
R902.1 Roofing Covering Materials. Roof coverings shall be class A or B, except that no
wooden shakes or shingles, treated or untreated, shall be permitted.”
