MOORPARK CITY COUNCIL
AGENDA REPORT
TO: Honorable City Council
FROM: Doug Spondello, Community Development Director
BY: Tom Juzwiak, Building Official
DATE: 11/05/2025 Regular Meeting
SUBJECT: Consider Ordinance Adopting by Reference the 2025 Editions of the
California Building Code, Volumes 1 and 2, with Appendices C, I and J,
the California Residential Code, with Appendix BF, the California
Referenced Standards Code, the California Electrical Code, the
California Plumbing Code, with Appendix H, the California Mechanical
Code, the California Energy Code, the California Green Building
Standards Code, the California Administrative Code, the California
Wildland-urban Interface Code, the 2024 Edition of the International
Property Maintenance Code, and the GA-600-2024 Gypsum
Association Fire Resistance Design Manual; Together with
Amendments, Deletions and Penalties; Amending Title 15 of the
Moorpark Municipal Code; and Approving a CEQA Exemption
Determination; and Consider Resolution Making Findings that
Amendments to the 2025 Editions of the California Building Code and
California Residential Code are Reasonably Necessary Due to Local
Climatic, Geological and/or Topographical Conditions
BACKGROUND
New building standards have been adopted by the State to take effect on January 1,
2026. 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.
DISCUSSION
The proposed Ordinance (attached), which would take effect on January 1, 2026,
concurrently with the new State standards, includes adoption of the State standards,
Item: 9.B.

Honorable City Council
11/05/2025 Regular Meeting
Page 2
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 in Ventura County as a unified consortium agreed to recommend
adoption of these additional amendments (which exceed the 2025 California Building
Standards Code) 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 2025 California Building Code and Residential Code
are essentially the same as those made to the 2022 Codes by City Ordinance No. 508,
and include stricter standards for foundation design, swimming pools, expansive soil
conditions, fire-resistive construction including roof materials, unreinforced footings, and
engineered truss systems.
As a requirement for adoption of Codes by reference, State law requires that the Council
direct staff to advertise a public hearing, notice of which must be published at least 15
days prior to the hearing and consideration of second reading of the Ordinance.
Additionally, the City is required to file the Ordinance and findings resolution with the
California Building Standards Commission before they will become effective. The City
Attorney has reviewed and approved the form of the Ordinance.
Due to the approval of Assembly Bill 130, and for the period of October 1, 2025, to June 1,
2031, the State of California has prohibited cities from considering, approving, or adopting
any proposed building standards affecting residential units that were not in effect as of
September 30, 2025, unless certain conditions are met, including amendments that the
Building Standards Commission deems necessary as emergency standards to protect
the health and safety of the community. Therefore, there are no new proposed code
amendments since the last code adoption cycle.
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
None.

that this Ordinance amending Title 15 of the Moorpark Municipal Code is exempt from the

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.

RESOLUTION NO. 2025-____
A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF
MOORPARK, CALIFORNIA, MAKING FINDINGS THAT
AMENDMENTS TO THE 2025 EDITIONS OF THE
CALIFORNIA BUILDING CODE AND CALIFORNIA
RESIDENTIAL CODE ARE REASONABLY NECESSARY
DUE TO LOCAL CLIMATIC, GEOLOGICAL AND/OR
TOPOGRAPHICAL CONDITIONS
WHEREAS, certain building standards and other related provisions contained in
national model and uniform codes are adopted and amended by the State of California,
and thereafter published as the California Building Standards Code (“CBSC”). The 2025
CBSC will become applicable in the City, subject to amendments made by the City
pursuant to Health and Safety Code Sections 17958.5 and/or 18941.5; and
WHEREAS, Health and Safety Code Sections 17958.5 and 18941.5 authorize
the City Council to make reasonably necessary modifications to the California Building
Standards Code, based on certain local conditions; and
WHEREAS, Health and Safety Code Section 17958.7 requires that, before
making any modifications to building standards contained in the CBSC, the City Council
shall make an express finding that each such modification is reasonably necessary
because of local climatic, geological, or topographical conditions; and
WHEREAS, The City’s Building & Safety Division Community Development
Department has recommended that modifications be made to building standards and
other provisions contained in the CBSC, and has advised that certain modifications are
reasonably necessary due to local conditions. City’s Building & Safety Division
Community Development Department has further advised that the remainder of such
modifications are of an administrative or procedural nature, or concern themselves with
subjects not covered by the CBSC or are reasonably necessary to safeguard life and
property within the City of Moorpark; and
WHEREAS, The City Council adopts this Resolution in order to make required
findings concerning building standards adopted and/or amended in Ordinance No. 530;
and
NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF MOORPARK
DOES HEREBY RESOLVE AS FOLLOWS:
SECTION 1. 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 2025 Editions of the California
Building Code and California Residential Code and adopted by Ordinance No. 530, is
reasonably necessary due to local climatic, geological and/or topographical conditions
as follows:

Resolution No. 2025-____
Page 2
A. 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. In addition, 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. These factors require specific and
greater protection than is afforded by the California Building Code or California
Residential Code.
B. 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 the California Building Code or California Residential Code.
C. 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.
SECTION 2. Amendments to the 2025 California Building Code (“CBC”) and
2025 California Residential Code (“CRC”) adopted by the City and identified below are
found reasonably necessary based on the climatic, geological, and/or topographical
conditions described in Section 1, subsections A through C, of this Resolution and are
listed as follows:
