Appendices and Model Ordinances (vegetation plans, severity‑zone adoption, home‑hardening guidance)

This hub orients readers to the CWUIC appendices and model ordinance tools for vegetation plans, severity‑zone adoption, and home‑hardening guidance.

Last reviewed: July 6, 2026

Overview

This area of the California Wildland‑Urban Interface Code collects the informational appendices and model ordinance language that local agencies use to translate WUI safety principles into plans, maps, and homeowner guidance. It includes vegetation‑management plan criteria (what to show and how to size fuel‑management zones), community evaluation tools, model ordinance language for adopting fire hazard severity zones, and voluntary home‑hardening recommendations—all aimed at reducing structure ignitions and improving emergency response in high‑risk areas. See the vegetation plan requirements in §603.3–§603.4 for required landscape plan contents and fire‑smart planting rules .

Key materials here are the Vegetation Management Plan appendix (Appendix B, B101) and its landscape/maintenance focus; the Model Ordinance for Fire Hazard Severity Zone Adoption (Appendix D, §D101) for local designation and ordinance text; the Characteristics of Fire‑Smart Vegetation (Appendix F, F101) as a planting guide; and the Voluntary Home‑Hardening Recommendations (Appendix G, G101) for structural survivability and defensible‑space features .

    Appendix C contains a preliminary Community WUI Fire Hazard Evaluation Framework as a suggested methodology to begin to support communities at risk in the identification of their unique hazards and to provide common metrics for comparisons between communities. This preliminary framework includes information on community size, population and fuels; on notification and evacuation; and on the community infrastructure and firefighting response potential. Aspects of this framework may already be included in various community- level documents, such as Community Wildfire Protection Plans or evacuation plans. Development of a standard framework will (1) consolidate relevant WUI fire hazard and planning information in one place, and (2) allow for cross-community comparisons.

    The evaluation required to implement this framework will support prefire hazard assessment and during-fire response operations. An increased understanding of fire evacuation, fire structural response and fire defensive action relationships is needed to assess the over- all community WUI fire hazard. The quantification of these relationships will enable communities to optimize the community-level response to WUI fire hazards in a more integrated approach and result in increased life safety and reduced losses.

    Appendix D Model Ordinance for Fire Hazard Severity Zone Adoption.

    Appendix D is an informational appendix that is a sample ordinance designed as guidance for a city, county, city and county, or fire district to establish and designate fire hazard severity zones within their jurisdiction.

    Appendix E Reserved.

    Appendix F Characteristics of Fire-Smart Vegetation.

    Appendix F is an informational appendix provided for the convenience of the code user. It is simply a compilation of the eight characteristics of fire-smart vegetation that can be used effectively within wildland-urban interface areas to reduce the likelihood of fire spread through vegetation.

    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.

    The chapter includes mitigation strategies to reduce the hazards of fire originating within a structure spreading to wildland and fire originating in wildland spreading to structures.

    Chapter 7 Referenced Standards.

    Chapter 7 lists all of the product and installation standards and codes that are referenced throughout Chapters 1 through 6 and includes identification of the promulgators and the section numbers in which the standards and codes are referenced. As stated in Section 102.4, these standards and codes become an enforceable part of the code (to the prescribed extent of the reference) as if printed in the body of the code.

    Appendix A General Requirements.

    Appendix A, while not part of the code, can become part of the code when specifically included in the adopting ordinance. Its purpose is to provide fire-protection measures supplemental to those found in Chapter 6 to reduce the threat of wildfire in a wildland-urban interface area and improve the capability for controlling such fires. This appendix includes detailed requirements for vegetation control; the code official’s authority to close wildland-interface areas in times of high fire danger; control of fires, fireworks usage and other sources of ignition; storage of hazardous materials and combustibles; bans on the dumping of waste materials and ashes and coals in wildlandurban interface areas; protection of pumps and water supplies; and limits on temporary uses within the wildland-urban interface area.

    Appendix B Vegetation Management Plan.

    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.

    Appendix C Community Wildland-Urban Interface (WUI) Fire Hazard Evaluation Framework.

    Appendix C contains a preliminary Community WUI Fire Hazard Evaluation Framework as a suggested methodology to begin to support communities at risk in the identification of their unique hazards and to provide common metrics for comparisons between communities. This preliminary framework includes information on community size, population and fuels; on notification and evacuation; and on the community infrastructure and firefighting response potential. Aspects of this framework may already be included in various community- level documents, such as Community Wildfire Protection Plans or evacuation plans. Development of a standard framework will (1) consolidate relevant WUI fire hazard and planning information in one place, and (2) allow for cross-community comparisons.

Frequently asked questions

What do vegetation management plans need to show?

Landscape plans must delineate fuel‑management zones (notably the 30‑ and 100‑foot zones), identify existing and proposed plantings, irrigated areas, and a plant legend; see §603.3 for the required contents and §603.4 for fire‑smart vegetation criteria .

How should a jurisdiction adopt fire hazard severity zones?

Appendix D provides a model ordinance (see §D101) that jurisdictions can use as a template to establish and map fire hazard severity zones within Local Responsibility Areas (LRA) and to specify administrative procedures for adoption and appeals .

Are home‑hardening items mandatory?

Appendix G offers voluntary home‑hardening recommendations (G101) intended as guidance for owners to improve structural survivability; these are informational and not mandatory unless a local adopting ordinance specifically incorporates them into enforceable requirements .
