CWUIC · California Wildland-Urban Interface Code

What Title 19 section numbers (e.g., T‑19 §1.11, §1.12, §1.08) are listed in the CWUIC matrix?

The CWUIC Appendix H matrix reprints selected California CCR, **Title 19** section numbers (notably **T‑19 §1.11**, **§1.12**, **§1.08**, and **§1.13**) next to CWUIC Chapter 1 entries; these reprints are informational — the authoritative regulatory text remains CCR Title 19 and the matrix does not change Title 19’s scope or appeal procedures.

What the code requires — 2–4 sentences

The California Wildland‑Urban Interface Code (CWUIC) uses a non‑regulatory matrix to reprint selected California Code of Regulations, Title 19, Division 1 sections for the user’s convenience. The matrix shows which T‑19 section numbers are printed alongside CWUIC chapter/section headings (it does not change their scope or appeal rights). See the matrix entries tied to § 1.11.2.1.1 and § 1.11.2.3 for the Chapter 1 Title‑19 cross‑references in the CWUIC .

The CWUIC matrix reprints selected CCR Title 19 section numbers next to the CWUIC sections (for example T‑19 §1.11, T‑19 §1.12, T‑19 §1.08); the matrix is informational and does not alter Title 19’s scope or procedures.

Requirements in detail

Which Title 19 section numbers appear in the CWUIC matrix (decision‑relevant list)

The CWUIC Appendix H matrix shows the following Title 19 section numbers adjacent to Chapter 1 / Division I entries:

Title 19 section (as shown in CWUIC matrix) CWUIC location / title in matrix Code reference (CWUIC §) Source
T‑19 §1.11 Enf. of Regulations / Office of the State Fire Marshal § 1.11 / § 1.11.2.1.1
T‑19 §1.12 Enforcement Agency (listed with §1.11) § 1.11 / § 1.11.2.1.1
T‑19 §1.08 Report of Arrest (matrix entry under Chapter 1) § 1.11.2.2 (matrix cross‑reference)
T‑19 §1.13 Penalty (matrix entry) § 1.11.2.2 (matrix cross‑reference)

Notes:

  • The table above lists the Title 19 sections shown in the CWUIC matrix for Chapter 1 items visible in Appendix H. The matrix shows the Title 19 section number in square‑bracket form (for example [T‑19 §1.11]) beside the corresponding CWUIC entry.
  • The CWUIC matrix is organized in the same order the Title 19 text appears in the CWUIC and explicitly states these Title 19 provisions are reprinted for convenience (scope/appeals unchanged).

How to read the matrix entries that list T‑19 numbers

  • The matrix rows pair a CWUIC section (left column) with the reprinted CCR Title 19 section number (right column). Example: the row for CWUIC 1.11.2.1.1 — Responsibility for enforcement is associated with T‑19 §1.11 and T‑19 §1.12 in the matrix.
  • The matrix is explicitly labeled non‑regulatory and intended as an aid; presence of a T‑19 section in the matrix means it is reprinted in the CWUIC, not that CWUIC changes the regulatory content of Title 19.

Exceptions & special cases

  • The matrix is informational only — it does not change the scope, applicability, or appeals procedures of CCR, Title 19, Division 1. Users must consult the official CCR Title 19 text for regulatory interpretation. The CWUIC appendix states this plainly.
  • Not every CWUIC section has a T‑19 reprint; only those rows with the square‑bracketed [T‑19 §…] entries are Title 19 reprints (for example, the Chapter‑1 rows shown above). Where no [T‑19 §…] appears, no Title 19 provision is reprinted in that part of the CWUIC matrix.

Common mistakes

  • Mistaking “reprinted in the matrix” for “adopted or amended by the CWUIC.” The matrix expressly says the Title 19 text is a reprint for convenience and that Title 19’s scope/appeals remain the same. Do not assume the matrix entry amends Title 19.
  • Confusing CWUIC section numbers (e.g., § 1.11.2.1.1) with the CCR Title 19 section numbers (e.g., T‑19 §1.11). Each is separate; the matrix simply shows the mapping between them.
  • Relying only on the CWUIC matrix when an enforcement decision or appeal involves Title 19 obligations — always check the official CCR Title 19 text for binding regulatory language.

Worked example — concrete scenario

Scenario: a fire code official is reviewing who enforces wildfire‑related standards for a State‑regulated facility.

  1. The official opens CWUIC Appendix H and looks under Chapter 1 entries. They see the row connecting CWUIC § 1.11.2.1.1 — Responsibility for enforcement to [T‑19 §1.11] and [T‑19 §1.12] in the matrix. This shows the CWUIC has reprinted those Title 19 section numbers next to the CWUIC enforcement subsection.
  2. The official recognizes the matrix is informational and therefore pulls the authoritative CCR, Title 19 §1.11 and §1.12 to confirm the actual enforcement authority and procedures for that facility (because the matrix does not change Title 19’s text or appeal mechanisms).
  3. If the question is whether a local ordinance conflicts with State enforcement, the official follows the procedures in the actual Title 19 sections (not the matrix). The CWUIC matrix only helped identify which Title 19 sections to consult.

Related provisions

  • CWUIC § 1.11.2.1.1 — Responsibility for enforcement (matrix links to T‑19 §1.11 / §1.12)
  • CWUIC § 1.11.2.3 — More restrictive fire and panic safety building standards (matrix shows this CWUIC subsection in Appendix H)
  • CWUIC § 1.11.2.2 — Right of entry (matrix cross‑references and T‑19 entries such as §1.08 shown nearby)
  • CWUIC Appendix H — Matrix Adoption Tables (explanatory material that the Title 19 text is a reprint and non‑regulatory)

    ABOUT THE I-CODES

    The 2024 I-Codes, published by the ICC, are 15 fully compatible titles intended to establish provisions that adequately protect public health, safety and welfare; that do not unnecessarily increase construction costs; that do not restrict the use of new materials, products or methods of construction; and that do not give preferential treatment to particular types or classes of materials, products or methods of construction.

    The I-Codes are updated on a 3-year cycle to allow for new construction methods and technologies to be incorporated into the codes. Alternative materials, designs and methods not specifically addressed in the I-Code can be approved by the building official where the proposed materials, designs or methods comply with the intent of the provisions of the code.

    The I-Codes are used as the basis of laws and regulations in communities across the US and in other countries. They are also used in a variety of nonregulatory settings, including:

    Voluntary compliance programs.

    The insurance industry.

    Certification and credentialing for building design, construction and safety professionals.

    Certification of building and construction-related products.

    Facilities management.

    “Best practices” benchmarks for designers and builders.

    College, university and professional school textbooks and curricula.

    Reference works related to building design and construction.

    Code Development Process

    The code development process regularly provides an international forum for building professionals to discuss requirements for building design, construction methods, safety, performance, technological advances and new products. Proposed changes to the I-Codes, submitted by code enforcement officials, industry representatives, design professionals and other interested parties are deliberated through an open code development process in which all interested and affected parties may participate.

  • CWUIC § 2.1 Medium relevance — show source text

    The values listed for liquefied natural gas (LNG) are “typical” values. LNG is a mixture of hydrocarbon gases, and no two LNG streams have exactly the same composition.|

    G101.2.1 Use of the table. To use Table G101.2, read horizontally across the line of interest. For example, to determine the number of cubic feet of gas contained in 1.0 gallon (3.785 L) of liquid argon, find 1.000 in the column entitled “Volume of Liquid at Normal Boiling Point.” Reading across the line under the column entitled “Volume of Gas at NTP” (70°F and 1 atmosphere/14.7 psia), the value of 112.45 cubic feet (3.184 m [3] ) is found.

    G101.2.2 Other quantities. If other quantities are of interest, the numbers can be multiplied or divided to obtain the quantity of interest. For example, to determine the number of cubic feet of argon gas contained in a volume of 1,000 gallons (3785 L) of liquid argon at its normal boiling point, multiply 112.45 by 1,000 to obtain 112,450 cubic feet (3184 m [3] ).

Frequently asked questions

Which T‑19 sections does the CWUIC matrix show for Chapter 1?

The matrix shows T‑19 §1.11, T‑19 §1.12, T‑19 §1.08, and T‑19 §1.13 adjacent to CWUIC Chapter 1 entries in Appendix H.

Does the matrix change the legal effect of Title 19 text?

No. The matrix is a reprint for convenience only — the scope, applicability and appeals procedures of Title 19, Division 1 remain unchanged. Consult Title 19 directly for regulatory text.

If I see [T‑19 §1.11] in the CWUIC matrix, where do I find the regulatory language?

Use the CCR (California Code of Regulations), Title 19, Division 1, and go to § 1.11 in the official CCR text — the CWUIC matrix only tells you that that Title 19 section was reprinted for convenience.

Are all Title 19 sections reprinted in the CWUIC?

No. Only selected Title 19 sections are reprinted and indicated with [T‑19 §…] entries in the matrix. If a CWUIC row has no T‑19 bracket, no Title 19 reprint appears there.

Where do I look if the CWUIC matrix entry and the CCR disagree?

The official CCR (Title 19) text governs; the CWUIC matrix is informational. Resolve conflicts by referring to the official CCR publication and working with legal/adjudicative procedures described in Title 19.
