2025 Summary of California Code Changes 1
INTRODUCTION
During the 2024 Triennial Code Adoption Cycle, California state agencies reviewed the most recent editions of national model codes and standards, and made amendments and additions to most parts of the California Building Standards Code, Title 24 of the California Code of Regulations (Title 24). This publication contains information regarding substantive California changes of interest to code users as they familiarize themselves with the 2025 edition of Title 24. For ease of reading, this document uses all normal font style (no italics). When looking at Title 24, it is a good idea to learn about and understand the various margin markings, banners and text styles that will indicate where changes have been made to the code and what amendments are model code changes versus California amendments. An explanation of margin markings can be found in the preface of each part of Title 24.
State agency acronyms that may be used in this publication BSC – Building Standards Commission
CEC – California Energy Commission
DCA – Department of Consumer Affairs, Veterinary Medical Board DSA – Division of the State Architect
DWR – Department of Water Resources
HCD – Department of Housing and Community Development
OSHPD – Office of Statewide Hospital Planning and Development SFM – State Fire Marshal
For the applications of amendments adopted by the various state agencies, reference Chapter 1 of each part of Title 24.
The parts of Title 24 may be abbreviated as follows:
CBC – California Building Code, Part 2, Volumes 1 and 2 CRC – California Residential Code, Part 2.5
CMC – California Mechanical Code, Part 4
CPC – California Plumbing Code, Part 5
CWUIC – California Wildland-Urban Interface Code, Part 7 CFC – California Fire Code, Part 9
CEBC – California Existing Building Code, Part 10
CALGreen – California Green Building Standards Code, Part 11 CRSC – California Referenced Standards Code, Part 12
To avoid confusion with other acronyms, abbreviations are not used for the California Administrative Code (Part 1), California Electrical Code (Part 3) or California Energy Code (Part 6).
Attachment 3
2 2025 Summary of California Code Changes
Note that there were no significant updates to the California Historical Building Code, Part 8 of Title 24, or Part 12, the Referenced Standards Code, so they are not included in this summary. There are no changes to Part 8 because the State Historical Building Safety Board adopted the 2025 California Historical Building Code by carrying forward existing provisions from the 2022 edition without further amendment.
Model code developers:
Every three years the national model codes and standards are published, and by law California is required to incorporate specific model codes and standards into Title 24.
The model code publishers often issue significant code change documents explaining national code updates and the reasons for them. Links are provided below to assist in searching for this information for each of the publishers.
IAPMO – The International Association of Plumbing and Mechanical Officials (Parts 4 and 5)
2024 Uniform Mechanical and Plumbing Code publication webpage ICC – The International Code Council (Parts 2, 2.5, 7, 9 and 10) ICC’s 2024 Significant Changes publications (search each title separately) NFPA – National Fire Protection Association (Part 3)
2023 National Electrical Code Guide to Changes
In 2024, the model codes published by ICC underwent a substantial formatting change as part of their digital transformation strategy to improve the user experience and enhance readability by providing a cleaner, more modern look. All parts of Title 24 that are published by ICC—Parts 1, 2, 2.5, 6, 7, 8, 9, 10, 11 and 12—display the new singlecolumn format. Parts 3, 4 and 5, published by NFPA and IAPMO, retain the previous formatting style.
Additionally, some section renumbering occurred to align with the new structure, and existing California amendments made obsolete by new model code language have been repealed and deleted from the code.
Also, in 2021 the Office of Statewide Hospital Planning and Development (OSHPD) was renamed the Department of Health Care Access and Information (HCAI). Within HCAI, divisions were renamed “offices” and the building code development unit is now within HCAI’s Office of Statewide Hospital Planning and Development (OSHPD); therefore, the acronym used in Title 24 banners to indicate adoption by OSHPD will not change.
Please watch the California Building Standards Commission’s (CBSC) video About Title 24 to learn about the code's layout and contributing state agencies. For more indepth information, visit CBSC’s Resources webpage to view and download educational publications such as a Guide to Title 24.

Office of Statewide Hospital Planning and Development
1705 Required special inspections and tests
Updated and aligned with model code revisions.
1705.2.1 Structural steel
Adopted model code provisions and aligned with current practice. Model code provisions changed significantly and updates to the American Institute of Steel Construction (AISC) 360 standard created an unintended gap in special inspection requirements. AISC 360 Section N5 Item # 3 and Section N6 are not adopted for consistency with Sections 1704.2 and 1704.2.5.1, respectively (no material change intended). Added a note to explain the difference in terminology used by AISC and the CBC.

1705A.2.7 Special Inspection and tests of structural welding Added reference pointers. Recognized AWS B5.1 as an alternative acceptable standard for AWS CWI minimum requirements to AWS QC1. Replaced ‘inspection’ with ‘special inspection’ throughout this section to clarify requirements apply to QA, rather than QC inspections.
Table 1705A.3 Required special inspections and tests of concrete construction Coordinated various editorial amendments to correct numbering inconsistences and to update and clarify certain amendments due to reformatting of the model code table. Amendments include, but are not limited to:
• Added ACI 318 reference pointers.
• Items 1, 4.a, 4.b, 5, 6, 7, and 14 – Renumbered reference pointers based on renumbering or relocation of previous amendments.
• Item 2.b – Adopted revised model language and amended the required inspection type to include intermediate moment frames. Added language and DSA banner to address specific cases of welding of reinforcing used in collectors and chords.
• Item 2.d – Deleted amendment regarding reinforcing steel resisting flexural and axial forces in intermediate and special moment frames, and boundary elements and coupling beams of special structural walls of concrete due to Item 2.b model code and amendments incorporating these requirements. Adopted model code inspection type.
• Items 3, 4.a and 4.b – Deleted amendments that were pointers to referenced standards because the model code now includes the pointers. • Item 5 and 6 – Relocated reference ACI 318-19 26.13.3.2 in Item 5 to Item 6.
For Item 5, repealed amendment requiring continuous special inspection to align with model code requiring periodic. However, no net regulatory change occurs because the California Administrative Code requires continuous inspection of concrete placement of the specified design mix.
1705A.4 Masonry construction
Added batch plant special inspection requirements for grout with reference to 1705A.3.3.
1705A.4.1.1 TMS 602 Section 1.6 Quality Assurance

Attachment 3
28 2025 Summary of California Code Changes
1705A.5.1 High-load diaphragms
Added reference to 2307.1 since special inspection is required for high-load diaphragms regardless of design method utilized being ASD or LRFD. 1705A.13 Special inspections for seismic resistance
1705A.13.1 Structural steel
1705A.13.1.1 Seismic force-resisting systems
1705A.13.1.2 Structural steel elements
1705A.14.1.1 Seismic force-resisting systems
1705A.14.1.2 Structural steel elements
Amended sections 1705A.13.1.1, 1705A.13.1.2, 1705A.14.1.1 and 1705.14.1.2 to clarify that requirements of the CBC are also applicable, in addition to those in the AISC 341. Deleted reference to gravity Section 1705A.2.1 in sections 1705A.13.1.1 and 1705A.13.1.2 since the seismic requirements in the AISC 341 builds on the gravity requirements in AISC 360.
1705A.14.2 Nonstructural components
Removed a pointer to Section 1704A.5, since the associated certification requirement is deleted in Section 1704A.5 Item #2. Revised existing amendment to include nationally recognized standards such as ANSI/ASHRAE 171 referenced in ASCE 7 Section C13.6.4.1.
Division of the State Architect
1701A.4 Special inspections and tests
Added reference to Chapters 14, 15 and 24 to the list of chapters with special inspection and test requirements to account for those in the noted chapters.
Removed the specific reference pointer to the California Administrative Code (CAC) since many different sections specify special inspection, test, and observation requirements and a comprehensive listing is not needed. 1704A.3 Statement of special inspections
Added language to not permit the exception that allows non-licensed individuals to prepare a statement of special inspections. The California Education Code Section 17302 requires designs of school projects by design professionals. 1704A.4 Contractor responsibility
DSA's construction oversight and quality assurance programs render requirements for the contractor to submit a statement of responsibility unnecessary for most projects. Therefore, only when such a requirement is specified on the approved construction documents does it apply.
1705A.2.1 Structural steel
Clarified prohibition of quality assurance aspects (rather than all aspects, such as quality control) for AISC 360, Chapter N, N5 Item 2 (Quality Assurance), N5 Item 4 (Inspection of Welding), and N7 (Nonconforming Material and Workmanship).
Attachment 3
2025 Summary of California Code Changes 29
Added a note clarifying that additions to other reference standards in Table 1705A.2.1 apply when those provisions are applicable.
Clarified intent of replacing language in AISC 360, Section N5.5(b) and through formatting for consistency with modification of model reference standards used in other amendments.
DSA considered deleting non-adoption of some AISC 360 Chapter N references as well as the reference to Table 1705A.2.1. However, based on early feedback from various welding special inspectors and material testing laboratory managers, confusion regarding expectations caused by the terms “observe,” “perform,” and “document” not correlating with periodic or continuous inspection, DSA decided to maintain those.

CALIFORNIA ENERGY CODE – PART 6
Please visit the California Energy Commission’s website for Part 6 updates. energy.ca.gov/programs-and-topics/programs/building-energy-efficiencystandards/online-resource-center/overview CALIFORNIA WILDLAND-URBAN INTERFACE CODE – PART 7
Overview
The new California Wildland-Urban Interface Code (CWUIC), based on the International Wildland-Urban Interface Code, was created by relocating chapters, sections and language from several parts of Title 24, including the California Building Code (Chapter 7A), California Residential Code (Section R337) and the California Fire Code (Chapter 49). Additionally, it incorporates other provisions from Title 24 (not relocated), and sections from Title 14 (Natural Resources) and Title 19 (Public Safety) of the California Code of regulations, and sections from the Government Code, the Health and Safety Code, and Public Resources Code.
Section H107, Cross Reference Tool, was added to Appendix H of the CWUIC. It lists each section of the code and identifies the source document and section for each provision.
As part of the effort to consolidate language from the multiple areas of law and regulations, a reasonable amount of “clean-up” was made before codifying the language into the CWUIC. This consisted of clarifying intent, correcting minor errors from previous code cycles, and reorganizing sections to align with model code.
Attachment 3
