CWUIC · California Wildland-Urban Interface Code

Where does the matrix show Title 14 (Div. 1.5) vs Title 19 (Div. 1) cross‑references for a CWUIC section?

Use the CWUIC Appendix H Cross Reference Table (§ H107) to find whether a CWUIC section points to a Title 19 reprint or a Title 14 reprint; Title 14 items are reprinted in the CWUIC body with square brackets and are listed in Appendix H for convenience, while the matrix itself is a nonregulatory index.

What the code requires — 2–4 sentences

The California Wildland‑Urban Interface Code requires that cross‑references to other California regulations be available to the user through the Cross Reference Table in Appendix H, Section H107. The code also directs that provisions taken from CCR, Title 14, Division 1.5 are shown in the body of the CWUIC with square brackets and that the Cross Reference Table in Appendix H is the tool for locating corresponding Title 14 and Title 19 sections; see § H107 and § 1.12.2 for these directions.

The single most important rule: use the Appendix H Cross Reference Table (§ H107) to find whether a CWUIC provision is a reprint from Title 19 (Div. 1) or has a referenced Title 14 (Div. 1.5) section; Title 14 text is reprinted for convenience and is identified in the body by square brackets.

Requirements in detail

What the matrix (Appendix H) is and how it is organized

  • Matrix Adoption Tables are a non‑regulatory, user‑aid summary that lists CWUIC sections alongside corresponding sections in other California codes (including Title 14 (Div. 1.5) and Title 19 (Div. 1)). The tables are descriptive only — they do not change the scope or applicability of the referenced regulations.
  • The matrix columns include separate columns for a CWUIC section and for the matching Title 14 and Title 19 section numbers (when applicable). Use the CWUIC section row to read across to the Title 14 and Title 19 columns to find cross‑references.

How Title 14 vs Title 19 are indicated

  • Title 19 (Div. 1) provisions that are reprinted in the CWUIC will ordinarily appear in Appendix H with a Title 19 column entry and (in CWUIC table headers) may be marked in the matrix as adopted/reprinted; Appendix H shows which CWUIC sections correspond to Title 19 sections. See examples of the T‑19 column entries.
  • Title 14 (Div. 1.5) provisions reprinted in the CWUIC are not listed in the Matrix Adoption Tables as being adopted by the State Fire Marshal (because Title 14 is outside the SFM adoption authority). Instead, Title 14 text appears in the CWUIC body where it is reproduced for convenience and is identified in the body by square brackets that reference the applicable Title 14 section. For those Title 14 items you will still find cross‑reference entries in Appendix H’s table (Title 14 column) that point to the original Title 14 section.

Quick decision table — where to look and what it means

Decision question Possible values Where the matrix shows it Code reference
Is the CWUIC section a reprint from Title 19? Yes / No Check the Title 19 column in Appendix H row for that CWUIC section; a Title 19 section number or indicator will be shown. § H107; Appendix H matrix
Is the CWUIC section from Title 14 (Div. 1.5)? Yes / No The CWUIC body will show the Title 14 citation in square brackets; Appendix H lists the Title 14 section in the Title 14 column (note: Title 14 material is reprinted for convenience and not adopted by SFM). § 1.12.2; Appendix H matrix
Is the matrix legally binding? No Matrix Adoption Tables are nonregulatory aids — they summarize cross‑references but do not supersede the authoritative code text. Appendix H introductory notes

How to read the matrix row for a CWUIC section (step‑by‑step)

  1. Find the CWUIC section number in Appendix H (leftmost column).
  2. Read across to the Title 14 column — if populated, it shows the corresponding Title 14 (Div. 1.5) section number (these are reprints for convenience).
  3. Read across to the Title 19 column — if populated, it shows the corresponding Title 19 (Div. 1) section number and indicates that the CWUIC text is a reprint of CCR Title 19 material.
  4. Use the CWUIC body (square‑bracketed references) and the original cited Title 14/19 sections where you need the authoritative regulatory language; remember the matrix itself is only an index.

Exceptions & special cases

  • The matrix is expressly nonregulatory — it is an index and user aid only. Do not treat entries in Appendix H as an adoption action or as changing the legal scope of Title 14/19 provisions.
  • Title 14 (Div. 1.5) text is reprinted in the CWUIC for convenience but is not within the State Fire Marshal’s authority to adopt; therefore Title 14 provisions may be presented in the CWUIC body (square brackets) but are not “adopted” (see the explanatory note in Appendix H and the body text).
  • Appendix entries sometimes show an “X” or other adopting‑agency markers in different agency columns — read the column headers carefully (the SFM/T‑19/T‑24 columns differ by agency). A filled T‑19 indicator in the matrix simply identifies the original Title 19 section that corresponds to the CWUIC text.

Common mistakes

  • Mistaking the matrix for the regulatory text: the matrix is an index only; the authoritative regulatory language is the CWUIC body and the original Title 14/19 texts.
  • Assuming Title 14 entries in Appendix H mean the State Fire Marshal adopted those Title 14 provisions — Title 14 reprints are for user convenience only and are identified in the CWUIC body by square brackets.
  • Overlooking § 1.12.2, which explicitly directs users that Title 14 references are shown in the body and that Appendix H (H107) contains the cross reference table. Always check both the CWUIC section text and § H107.

Worked example — concrete scenario

Scenario: you are reviewing CWUIC section 503.2.4.3.1 and need to know whether the provisions are a Title 14 reprint or a Title 19 reprint.

Step 1 — find the row for CWUIC 503.2.4.3.1 in Appendix H. The matrix row lists the corresponding Title 14 entry as 703A.5.2 (Title 14) in the Title 14 column. Use the Title 14 column entry to locate the original Title 14 language if needed.

Step 2 — check the Title 19 column for that same row. If the Title 19 cell is blank (or not populated for that row), then this CWUIC row is referencing a Title 14 provision only — the CWUIC body will show the Title 14 reference in square brackets. If the Title 19 column had a section number (or if the T‑19 column shows an adoption mark), then the CWUIC language would be a reprint of Title 19 material. Refer to the CWUIC body and the original Title 14/19 texts for the regulating language.

Concrete numeric read: Appendix H shows CWUIC 503.2.4.3.1 → Title 14 703A.5.2 (no Title 19 entry in that row), therefore treat the CWUIC text as a reproduction/reference to the Title 14 provision (reprinted for convenience). Confirm the CWUIC body square‑bracket citation and then consult Title 14 §703A.5.2 for the full authoritative text.

Related provisions

  • § H107 — Cross Reference Tool (Appendix H).
  • § 1.12.2 — Agency identification; notes square‑bracket Title 14 references and points to Appendix H, § H107.
  • Appendix H introductory notes — Matrix Adoption Tables are nonregulatory, user aids.
  • Appendix H, H104 — references to Title 14 material summarized in the Appendix.
  • Appendix H, H105 — references to Title 19 material summarized in the Appendix.

    6 FIRE PROTECTION REQUIREMENTS

    User notes:

    About this chapter: In addition to the building construction requirements in the California Building Code and California Residential Code, this chapter contains requirements for development and construction in Local Responsibility Areas (LRA) designated as Very High Fire Hazard Severity Zones and areas designated by the State Fire Marshal as State Responsibility Areas (SRA). While many of these provisions are found in Title 14 and Title 19 of the California Code of Regulations, they are replicated here for the code user. The local jurisdiction has the authority to apply the same regulations to LRA when the regulations are adopted by local ordinance.

    The requirements in this chapter reference the process for adoption of Very High Fire Hazard Severity Zones in the LRA; criteria for evaluating existing subdivisions that are at significant fire risk and are without an adequate secondary egress; and criteria for fire safety provisions required in the Safety Element of a city or county General Plan.

    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.

Frequently asked questions

How do I tell at a glance whether a CWUIC section is a Title 19 reprint?

Look up the CWUIC section row in Appendix H and check the Title 19 column — if populated with a Title 19 section number or indicator, that shows the CWUIC text corresponds to Title 19 material. See § H107 and the matrix.

Where are Title 14 reprints shown in the CWUIC?

Title 14 (Div. 1.5) text reprinted for convenience is identified in the CWUIC body by square brackets, and the Appendix H Title 14 column lists the original Title 14 section. See § 1.12.2 and Appendix H.

Is the Appendix H matrix regulatory?

No — the Matrix Adoption Tables are nonregulatory aids intended to help users locate corresponding sections; they do not change the regulatory text or adoption status.

If Appendix H shows both Title 14 and Title 19 entries for a CWUIC section, which controls?

Always read the authoritative regulatory language in the CWUIC body and the original Title 14/Title 19 texts. Appendix H simply shows the correspondence; the adoption/authority depends on each original source (Title 19 reprints in CWUIC are reprints of CCR Title 19; Title 14 is reprinted for convenience but not adopted by SFM).

Where is the Cross Reference Table located?

The Cross Reference Table is in Appendix H, Section H107 of the CWUIC; § 1.12.2 directs users to that table for finding Title 14/19 references.
