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.
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.
PASSED AND ADOPTED this 2nd day of November, 2022.

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

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

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."
