CCR Title 14 (Div. 1.5) cross-references, SRA regulations, and Title 14 definitions

This page explains how CWUIC reproduces and cross‑references CCR Title 14 Division 1.5 SRA regulations and definitions—pointing readers to the key sections (e.g., §1270.01, §1270.02, §1270.06, §1276.03) used throughout the code.

Last reviewed: July 6, 2026

Overview

This hub orients readers to the portions of CCR Title 14 (Division 1.5) that the California Wildland‑Urban Interface Code (CWUIC) reproduces and cross‑references for State Responsibility Area (SRA) regulation, fire‑safe development, and definitional clarity. Title 14 Subchapter 2 establishes the State Minimum Fire Safe Regulations (see §1270.02 Purpose and §1270.03 Scope) that frame applicability to SRA and VHFHSZ areas and the basic measures for emergency access, water supply, and vegetation modification .

Key operational provisions you’ll see cross‑referenced throughout the CWUIC include inspection and administration rules (e.g., §1270.06 Inspections and §1270.07 Exceptions to Standards), and the SRA Fire Safe Development requirements and fuel‑management rules found in Chapter 7 (for example, fuel breaks and maintenance in §1276.03) — these are integrated into CWUIC chapters on inspection, subdivision review, and site development . The CWUIC also reproduces Title 14’s definitions (State Responsibility Area, Undeveloped/Strategic Ridgeline, Road, Structure, etc.) so users have the exact regulatory meanings available in context; see the Title 14 definitions compiled in §1270.01 and related definition sections .

Note: the CWUIC includes reprinted text from CCR Title 14 for user convenience; those Title 14 provisions are not adopted by the Office of the State Fire Marshal within the Matrix Adoption Tables and are provided as referenced material in the code text .

    CALIFORNIA ADMINISTRATION

    SECTION 1.1—GENERAL

    1.1.1 Title. These regulations shall be known as the California Wildland-Urban Interface Code, may be cited as such, and will be referred to herein as “this code.” The California Wildland-Urban Interface Code is Part 7 of thirteen parts of the official compilation and publica- tion of the adoptions, amendment, and repeal of building regulations to the California Code of Regulations, Title 24, also referred to as the California Building Standards Code. This part incorporates by adoption of the 2024 International Wildland-Urban Interface Code of the International Code Council (ICC) with necessary California amendments.

    1.1.2 Purpose. The purpose of this code is to establish minimum requirements to reduce the likelihood of life and property loss due to a wildfire through the use of performance and prescriptive requirements for construction and development in all Fire Hazard Severity Zones in State Responsibility Areas (SRA), and Local Responsibility Areas (LRA) designated as a Very High Fire Hazard Severity Zone, and increase the ability of buildings located in any Fire Hazard Severity Zone within State Responsibility Areas (SRA), or Wildland-Urban Inter- face (WUI) Areas, to resist the intrusion of flames or burning embers projected by a vegetation fire and contributes to a systematic reduction in conflagration losses and reduce the likelihood of life and property loss due to a wildfire.

    1.1.3 Scope. The provisions of this code shall apply to the construction, alteration, movement, enlargement, replacement, repair, equip- ment, use and occupancy, location, maintenance, removal, and demolition of every building or structure or any appurtenances connected or attached to such building structures throughout the State of California.

    This code establishes regulations affecting or relating to buildings, structures, processes, premises, and a reasonable degree of life and property safeguards regarding: 1. The hazard of fire and explosion arising from the storage, handling, or use of structures, materials, or devices. 2. Conditions hazardous to life, property, or public welfare in the use or occupancy of buildings, structures, or premises. 3. Fire hazards in the buildings, structures, orp on-premises from use of, occupancy of, or operation. 4. Matters related to the construction, extension, repair, alteration, or removal of fire suppression or alarm systems. 5. Conditions affecting the safety of firefighters and emergency responders during emergency operations.

Frequently asked questions

What is an SRA (State Responsibility Area)?

An SRA is land classified under the Public Resources Code where the state has primary financial responsibility for preventing and suppressing wildfires; the CWUIC reproduces the Title 14 definition and applies Title 14 SRA rules to siting, access, and defensible‑space requirements .

How does CWUIC use Title 14 cross‑references?

CWUIC embeds Title 14 text as reprinted cross‑references so code users see the exact regulatory language (definitions, inspection procedures, exceptions, and SRA development rules) alongside CWUIC provisions; those Title 14 passages are identified in the code body and Appendix cross‑reference tables .

Where are the SRA “Fire Safe Development” rules?

SRA Fire Safe Development regulations are located in Title 14, Division 1.5, Chapter 7 (Subchapter 1 and Subchapter 2 references appear in CWUIC sections on subdivision review and development); fuel break and greenbelt requirements are set out in sections such as §1276.03 and §1276.04 and are cited where CWUIC discusses fuel modification and site planning .
