CWUIC · California Wildland-Urban Interface Code

Code Official, Agency and Enforcement

This section of the CWUIC establishes the enforcing agency and code official’s authority, the permit/inspection/enforcement procedures, and the appeals process.

Last reviewed: July 6, 2026

Overview

This area of the California Wildland‑Urban Interface Code (CWUIC) covers the administration and enforcement framework that makes the WUI technical requirements legally effective — the creation of the enforcing agency, appointment of the code official and deputies, permitting, inspections, enforcement actions, certificates and appeals (Part 2, Sections 103–113).

It matters because the code official is the named authority who interprets the CWUIC, issues permits, requires technical reports, and takes enforcement actions to protect life and property; those powers and duties are set out explicitly in § 103 and § 104 and carry procedural duties (e.g., permits, inspections, stop‑work, certificates) that implement the technical chapters. The CWUIC also incorporates enforcement roles from California regulations: the State Fire Marshal and local fire chiefs remain enforcement entities under Title 19/CCR where applicable.

Key regulatory touchpoints in this part include § 103 (Code Compliance Agency), § 104 (Duties and Powers of the Code Official), § 105 (Permits), § 109 (Inspection and Enforcement), § 112 (Means of Appeals) and § 113 (Stop Work Order); procedural appendices such as the Board of Appeals supplement the appeals process where adopted.

    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.

Frequently asked questions

Who is the “code official” under the CWUIC?

The code official is the jurisdiction’s designated official charged with interpreting and enforcing the CWUIC (or the code official’s authorized representative). This definition and role are set out in the code’s definitions and in the appointment/agency provisions of Chapter 1.

How do I challenge a decision by the code official?

Decisions of the code official may be appealed through the Means of Appeals procedure (Section 112) and, where adopted, to a local Board of Appeals under Appendix I; appeals can stay enforcement of notices except in imminent danger cases.

Which agencies enforce the CWUIC in California?

Enforcement may be carried out by the State Fire Marshal, local city or county fire chiefs or their authorized representatives consistent with CCR Title 19 and the CWUIC adoption matrix; local jurisdictions also implement the code via their appointed code official.
