Overview

The CWUIC cross-reference matrix (Appendix H, SECTION H107) is a table that maps every CWUIC section to its source documents and equivalent provisions in other California codes (for example the CBC, CFC, Title 14/19 regulations, PRC and HSC). The matrix identifies the originating authority, adopted status, and the exact section citations so you can trace where each CWUIC requirement came from and follow the original language when needed. See SECTION H107—CROSS REFERENCE TOOL and the Appendix H matrix pages for examples of the column layout and mapping logic .

Why this matters: reviewers, code officials, designers and building departments use the matrix to confirm whether a CWUIC provision is state‑adopted, to locate corresponding provisions in the CBC/CFC or state regulations, and to determine the proper order of precedence when provisions differ. The matrix covers core chapters you’ll use most often — administration and scope (e.g., §1.1 and §101), area designation and mapping (e.g., §302.1), special building construction such as ignition‑resistant requirements (e.g., §503 and §504), and fire protection requirements including fire protection plans and defensible‑space maintenance (e.g., §602 and §604) .

How to use the matrix quickly: locate the CWUIC section number in the left column of Appendix H, read across to see the “Adopted” flag and the referenced source columns (CBC, CFC, Title 14/19, PRC, HSC). If the matrix shows a counterpart in another code, open that cited section to confirm technical details or exceptions; use the order‑of‑precedence rules in Chapter 1 when conflicts arise. The matrix is intended as a navigational tool and adoption aid rather than a substitute for reading the full source provision .

(2) The publication date established by the commission shall be no earlier than the date the California Building Standards Code is available for purchase by the public. (b) Neither the State Building Standards Law contained in this part, nor the application of building standards contained in this section, shall limit the authority of a city, county, or city and county to establish more restrictive building standards, including, but not limited to, green building standards, reasonably necessary because of local climatic, geological, or topographical conditions.

  • CWUIC § 1-2 Medium relevance — show source text

    Population growth and the expanding urban development into traditionally nonurban areas have increasingly brought humans into contact with wildfires. According to the National Fire Protection Agency (NFPA), every year, wildfires burn across the United States and a growing number of people are living where wildfires are a real risk. In 2018 more than 58,000 fires burned nearly 9 million acres across the US. More than 25,000 structures were destroyed, including 18,137 residences and 229 commercial structures. California accounted for the highest number of structures lost in one state due to the number of significant fires, including the Mendocino Complex, Carr, Camp and Woolsey fires.

    The IWUIC is a model code that is intended to be adopted and used supplemental to the adopted building and fire codes of a jurisdiction. The unrestricted use of property in wildland-urban interface areas is a potential threat to life and property from fire and resulting erosion. The IWUIC has as its objective the establishment of minimum special regulations for the safeguarding of life and

    x 2025 CALIFORNIA WILDLAND-URBAN INTERFACE CODE

    on Jul 18, 2025 11:14 AM (CDT) THEREUNDER.

    property from the intrusion of fire from wildland fire exposures and fire exposures from adjacent structures and to prevent structure fires from spreading to wildland fuels, even in the absence of fire department intervention.

    Safeguards to prevent the occurrence of fires and to provide adequate fire protection facilities to control the spread of fire in wildland-urban interface areas are provided in a tiered manner commensurate with the relative level of hazard present.

    ARRANGEMENT AND FORMAT OF THE 2025 CWUIC

    The format of the CWUIC allows each chapter to be devoted to a particular subject. The following table shows how the CWUIC is divided. The chapter synopses detail the scope and intent of the provisions of the CWUIC.

    CHAPTER TOPICS Col2
    CHAPTER SUBJECT
    1-2 Administration and Definitions
    3-4 Wildland-Urban Interface Area Designation and Requirements
    5 Building Construction Regulations
    6 Fire Protection Requirements
    7 Referenced Standards
    Appendices A-I Adoptable and Informational Appendices

    Chapter 1 Scope and Administration.

    Chapter 1 establishes the limits of applicability of the code and describes how the code is to be applied and enforced. The provisions of Chapter 1 establish the authority and duties of the code official appointed by the authority having jurisdiction and also establish the rights and privileges of the design professional, contractor and property owner.

    Chapter 2 Definitions.

    Chapter 2 is the repository of the definitions of terms used in the body of the code. The user of the code should be familiar with and consult this chapter because the definitions are essential to the correct interpretation of the code and because the user may not be aware that a term is defined.

    Chapter 3 Wildland-Urban Interface Areas.

    Chapter 3 provides for the fundamental aspect of applying the code—the legal declaration and establishment of wildland-urban interface areas within the adopting jurisdiction, mapping of the area, periodic review and updates.

    Chapter 4 Wildland-Urban Interface Area Requirements.

    The requirements of Chapter 4 apply to all occupancies in the wildland-urban interface and pertain to all of the following:

    1. Fire service access to the property that is to be protected, including fire apparatus access roads and off-road driveways.

    2. Premises identification.

Frequently asked questions

Where do I find the cross‑reference matrix in the CWUIC?

The matrix is in Appendix H under SECTION H107—CROSS REFERENCE TOOL; Appendix H reproduces the matrix columns that map CWUIC sections to CBC, CFC, Title 14/19, PRC and HSC citations .

Does the matrix show whether a provision was adopted by the State Fire Marshal?

Yes — the matrix includes an “Adopted Yes/No” column so you can see at a glance which CWUIC provisions were adopted and which are informational or not adopted by the State Fire Marshal .

I’m performing plan review — how should I use the matrix?

Find the CWUIC section you’re reviewing, read the matrix row to identify the original source code and section numbers, then review those cited sections in the CBC/CFC or state regulations to confirm technical requirements and verification steps; apply Chapter 1 order‑of‑precedence if the provisions conflict .
