CWUIC · California Wildland-Urban Interface Code
Referenced California Documents & Matrix (CCR/Title 14 & 19 cross‑references, statutory references)
Appendix H and the Matrix Adoption Tables let you trace CWUIC requirements to CCR Title 14/19 provisions and the underlying California statutes.
Last reviewed: July 6, 2026
Overview
This hub covers Appendix H of the California Wildland‑Urban Interface Code (CWUIC) — the collection of reprinted California statutes, CCR provisions, and the Matrix Adoption Tables that cross‑reference CWUIC sections with the California Code of Regulations (CCR, Titles 14 & 19), building and fire codes, and state statutes. Appendix H is provided for user convenience to help interpret CWUIC obligations and shows where code text is drawn from other California authorities .
Why this matters: the Matrix Adoption Tables and referenced documents explain which CCR provisions are reprinted into the CWUIC (notably CCR, Title 19, Division 1), which Title 14 text is shown for convenience (but not adopted by the State Fire Marshal), and the statutory authorities that underpin WUI requirements — enabling code officials, designers and jurisdictions to trace obligations back to CCR sections and statutes .
Key places to look in the CWUIC include the administration and scope provisions in Chapter 1 (e.g., §101), the wildland‑urban interface area rules in Chapter 3 (e.g., §301.1), and the WUI area requirements and access/roadway rules (for example §403.2.3 on road sign installation and visibility), plus Appendix H (SECTION H101 and the Matrix Adoption Tables) where statutory and CCR cross‑references such as Civil Code disclosures (e.g., Civil Code §§1102.6f and 1102.19) are collected for reference .

Appendix G Voluntary Home-Hardening Recommendations.
Appendix G is an informational appendix that provides discussion of some elements of the proposed self-defense mechanisms and their role in enhancing the protection of exposed structures in the wildland-urban interface. The items provided in this appendix provide owners with suggestions for increasing the survivability of their structure. These items are not mandatory but can be considered by owners to increase the safety of structures.
Appendix H Referenced California Documents.
Appendix H contains portions of California statutes and regulations located in other documents. They are reprinted in Appendix H to aid the user in understanding the requirements applicable to wildland-urban interface areas and to provide a background for the provi- sions. Much of the text in the CWUIC is based on the requirements found in these other documents.
Appendix I Board of Appeals.
Appendix I contains the provisions for appeal and the establishment of a board of appeals. The provisions include the application for an appeal, the makeup of the board of appeals and the conduct of the appeal process.

User notes:
About this appendix: Appendix B, while not part of the code, can become part of the code when specifically included in the adopting ordinance. Its purpose is to provide criteria for submitting vegetation management plans, specifying their content and establishing a criterion for considering vegetation management as being a fuel modification.
SECTION B101—GENERAL
B101.1 Scope. Vegetation management plans shall be submitted to the code official for review and approval as part of the plans required for a permit.
B101.2 Plan content. Vegetation management plans shall describe all actions that will be taken to prevent a fire from being carried toward or away from the building. A vegetation management plan shall include the following information:
- A copy of the site plan.
- Methods and timetables for controlling, changing or modifying areas on the property. Elements of the plan shall include removal of slash, snags, vegetation that may grow into overhead electrical lines, other ground fuels, ladder fuels and dead trees, and the thinning of live trees.
- A plan for maintaining the proposed fuel-reduction measures.
B101.3 Fuel modification. To be considered a fuel modification for purposes of this code, continuous maintenance of the clearance is required.

PG&E-Prohibited Trees
Applicants must not plant the trees listed in Table B-7, “Do Not Plant These Trees Under or Within 15 Feet of Overhead Power Lines,” under or within 15 feet of overhead power lines. When mature, these trees affect PG&E’s ability to provide and maintain safe and reliable service. Many species of trees are not appropriate for confined spaces under electric lines, although they may be appropriate for other locations within a development or building site. The list is limited and does not include all varieties of unsuitable trees; however, applicants can use this information as a guideline when choosing an appropriate tree for planting near power lines. Applicants should plant trees that grow higher than 25 feet at maturity at least 15 feet to the side of overhead power lines .
2022 – 2023 B−12
Appendix B: Electric and Gas Service Documents
Under the botanical names of the trees, occasionally only the genus is listed. Applicants should not plant any types of trees within these genera under or within 15 feet of overhead power lines.

Frequently asked questions
What is the Matrix Adoption Table and how should I use it?
The Matrix Adoption Tables are a non‑regulatory aid in the CWUIC that map CWUIC sections to corresponding CBC/CFC sections, CCR Title 14/19 sections, and statutory citations so users can see source authority and which agency adopted each provision .
Are CCR Title 14 provisions adopted by the State Fire Marshal in the CWUIC?
No — CCR Title 14, Division 1.5 provisions included in the CWUIC are reprinted for user convenience and are identified with bracketed Title 14 references; they are not listed in the Matrix Adoption Tables as within the State Fire Marshal’s authority to adopt .
Where are the statutory citations (Gov. Code, PRC, HSC) shown?
Appendix H collects statutory excerpts and cross‑references (for example, PRC and Government Code references tied to §301.1 mapping). See SECTION H101 and the matrix columns that list Gov. Code, PRC and HSC entries for each CWUIC topic .
