CWUIC · California Wildland-Urban Interface Code

Where is the CWUIC statutory cross‑reference matrix that lists PRC, Gov Code and HSC citations for each section?

The CWUIC’s statutory cross‑reference matrix is in Appendix H, **§ H107**. It is an informational table that lists CWUIC sections alongside the originating Gov Code, PRC and HSC citations (and other source columns). Use the matrix as a pointer to the authoritative statutes and regulations, but verify legal obligations in the original PRC/Gov Code/HSC text and confirm appendix adoption locally. file

What the code requires — plain English (controlling §)

The Cross Reference Tool is located in Appendix H, § H107 of the California Wildland‑Urban Interface Code. § H107 provides a tabular matrix that identifies each CWUIC section and shows the originating source document and section (including columns for Gov Code, PRC, and HSC where applicable) so users can find the underlying statutory citations for a given CWUIC provision.

The single most important rule: the CWUIC’s cross‑reference matrix is an informational table in Appendix H § H107 that maps CWUIC sections to their source statutes and regulations — use it as a look‑up aid, not as substitute authority.

(§ H107 is also referenced from the code body where Title 14 reprints are noted; see § 1.12.2 directing readers to the Cross Reference Table in Appendix H.)

Requirements in detail

What § H107 contains

  • Purpose: A row for (virtually) every CWUIC section showing the source document and the specific section(s) from which the language derives. The table has distinct columns for items such as Gov Code, PRC, and HSC citations (plus CBC, CFC, CCR Title 14/19 where relevant).
  • Format: A spreadsheet‑style matrix; each CWUIC section is listed on the left and the right side contains the corresponding source citations (if any).
  • Scope note: Some columns (for example Title 14 CCR) are reprints or convenience reprints and may not be within the State Fire Marshal’s authority; the code explains when those reprints are provided for convenience.

When to rely on original statutes Always verify the cited PRC/Gov Code/HSC text for legal requirements (matrix is a pointer only) See § H107 description and nonregulatory note file

How to read the matrix (practical steps)

  1. Find the CWUIC section number you care about in Appendix H’s matrix under § H107.
  2. Read across the row to the Gov Code, PRC, and HSC columns to see any statutory sources listed.
  3. Use those statutory citations to pull the authoritative text (PRC, Gov Code, HSC) — the matrix itself is an index, not the controlling law.

Exceptions & special cases

  • The matrix is explicitly an informational tool and the Matrix Adoption Tables are described as nonregulatory — they are intended only as an aid to the user. Do not treat entries in § H107 as regulatory text.
  • Some columns reproduce CCR Title 14 language for convenience; those reprints may not reflect SFM adoption authority and are identified as reprints. Verify whether the reproduced Title 14 provisions are adopted or simply reprinted.
  • Appendix provisions generally apply only when the adopting jurisdiction has adopted the appendices. Confirm appendix adoption before treating matrix entries as binding for your jurisdiction (see § 101.2.1).

Common mistakes

  • Relying on the matrix as the legal authority instead of consulting the actual statute or regulation. The matrix points to sources; the statutory/regulatory text governs. file
  • Assuming every CWUIC row will list a Gov Code/PRC/HSC citation. Many CWUIC provisions are code‑originated and will have blank statutory columns — absence of a citation means no direct statutory origin is indicated in the matrix.
  • Forgetting that appendices and matrix tables only apply where adopted by the jurisdiction; check adoption status in Chapter 1 and local adopting ordinance.

Worked example — concrete scenario

You need to confirm whether CWUIC requirements for landscape plan contents point to a PRC or HSC statute.

  1. Look up § 603.3.1 (Landscape plans — Contents) in the CWUIC matrix in Appendix H, § H107. The matrix row for § 603.3.1 shows PRC 51182(a) and HSC 4291 as source citations.
  2. Use those statutory citations (PRC 51182(a) and HSC 4291) to read the authoritative statutory language and confirm obligations and enforcement provisions. The matrix gave you the right pointers; the PRC/HSC text carries the legal obligations.

(If your jurisdiction did not adopt Appendix provisions, confirm whether the CWUIC appendix and the matrix are binding locally before relying on them.)

    DIVISION II

    SCOPE AND ADMINISTRATION

    User notes:

    About this chapter: Chapter 1 establishes the limits of applicability of the code and describes how the code is to be applied and enforced. Chapter 1 is in two parts: Part 1–General Provisions (Sections 101–102) and Part 2—Administration and Enforcement (Sections 103–113). Section 101 identifies which buildings and structures come under its purview and references other California Codes as applicable.

    This code is intended to be adopted as a legally enforceable document and it cannot be effective without adequate provisions for its administration and enforcement. 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.

    Note: Sections adopted or amended by state agencies are specifically indicated by an agency banner or indicated in the Matrix Adoption Table.

    PART 1—GENERAL PROVISIONS

    SECTION 101—SCOPE AND GENERAL REQUIREMENTS

    [A] 101.1 Title. These regulations shall be known as the California Wildland-Urban Interface Code of [ NAME OF JURISDICTION ], hereinafter referred to as “this code.”

    [A] 101.2 Scope. This code applies to building materials, systems and/or assemblies used in the exterior design and construction of new buildings located within a wildland-urban interface (WUI) area and contains minimum requirements to mitigate conditions that might cause a fire originating in a structure to ignite vegetation in the wildland-urban interface (WUI) area, and conversely, a wildfire burning in vegetative fuels to transmit fire to buildings and threaten to destroy life, overwhelm fire suppression capabilities or result in large property losses.

    [A] 101.2.1 Appendices. Provisions in the appendices shall not apply unless specifically adopted.

    [A] 101.3 Purpose. The purpose of this code is to establish minimum regulations for the safeguarding of life and for property protection. Regulations in this code are intended to mitigate the risk to life and structures from intrusion of fire from wildland fire exposures and fire exposures from adjacent structures and to mitigate structure fires from spreading to wildland fuels. The extent of this regulation is intended to be tiered commensurate with the relative level of hazard present.

    The unrestricted use of property in wildland-urban interface areas is a potential threat to life and property from fire and resulting erosion. 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 shall be in accordance with this code.

(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. The governing body shall make the finding required by Section 17958.7 and the other requirements imposed by Section 17958.7 shall apply to that finding. Nothing in this section shall limit the authority of fire protection districts pursuant to subdivision (a) of Section 13869.7. Further, nothing in this section shall require findings required by Section 17958.7 beyond those currently required for more restrictive building standards related to housing.

Frequently asked questions

Where exactly do I open the cross‑reference matrix?

Open Appendix H, § H107 of the CWUIC — § H107 contains the matrix table mapping CWUIC sections to source statutes and regulations.

Is the matrix binding law?

No — the matrix and Matrix Adoption Tables are described as an informational, nonregulatory aid. Always verify obligations by reading the cited PRC/Gov Code/HSC text.

If Appendix H lists a Title 14 citation, is that adopted by the State Fire Marshal?

Not necessarily. Title 14 entries are often reprints for convenience and the code explains which CCR text is reprinted; check the code’s notes about reprints and SFM authority.

My jurisdiction didn’t adopt appendices — can I still use the matrix?

You can use the matrix as a research aid, but Appendix provisions apply only if adopted by the jurisdiction (see § 101.2.1). Confirm local adoption before treating appendix material as locally enforceable.

Where in the code does the matrix get referenced?

The code body points readers to the Cross Reference Table in Appendix H, § H107 (for example, § 1.12.2 mentions the location).
