Adoptable Appendices (A–Q) — When and how to use them
Appendices A–Q are optional CFC supplements (not mandatory unless adopted) that jurisdictions adopt by ordinance to provide detailed methods, forms, or local requirements tied to specific sections such as §503 and §507.
Last reviewed: July 6, 2026
Overview
Appendices A–Q are Part VII of the California Fire Code (the adoptable and informational appendices) and provide supplemental, often more detailed, methods, guidance and forms that jurisdictions may adopt by reference to extend or clarify the body of the CFC. Part VII is identified in the code as the appendices chapter for adoptable and informational material.
Appendices are not automatically mandatory — they are optional tools a local authority or state agency chooses to adopt by ordinance or matrix. When not adopted they remain advisory; when adopted they become enforceable as adopted. The model and California commentary note that appendix provisions are not mandatory unless specifically referenced or adopted.
Use the appendices when a local policy needs more prescriptive criteria than the body of the code (for example, Appendix D—Fire Apparatus Access Roads supplies detailed requirements used with §503; Appendix B provides a fire‑flow methodology tied to §507.3; Appendix C addresses hydrant spacing related to §507.5; Appendix H supplies HMMP/HMIS forms tied to §§407.5–407.6). Review the CFC’s appendix descriptions and any local matrix/adoption tables to see which appendices a jurisdiction or state agency has actually adopted.

California Building Code Correlated Topics
The CFC requirements for fire-resistance-rated construction, interior finish, fire protection systems, means of egress and construction safeguards are directly correlated to the chapters containing parallel requirements in the CBC as follows:
CFC/CBC CORRELATED TOPICS Col2 Col3 CFC CHAPTER/SECTION CBC CHAPTER/SECTION SUBJECT Chapter 7 Chapter 7 Fire and smoke protection features (Fire-resistance-rated construction in the CBC) Chapter 8 Chapter 8 Interior finish, decorative materials and furnishings Chapter 9 Chapter 9 Fire protection and life safety systems Chapter 10 Chapter 10 Means of egress Section 1203 Chapter 27 Emergency and standby power Chapter 31 Section 3103 Temporary structures Chapter 33 Chapter 33 Construction fire safety Chapters 50–67 Sections 307, 414, 415 Hazardous materials and Group H requirements PART I—ADMINISTRATIVE
Chapter 1 Scope and Administration.
Chapter 1 establishes the limits of applicability of the code and describes how the code is to be applied and enforced. 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.
Chapter 2 Definitions.
Chapter 2 is the repository of the definitions of terms used in the body of the code. The user of the code should be familiar with and consult this chapter because the definitions are essential to the correct interpretation of the code and because the user may not be aware that a term is defined.
PART II—GENERAL SAFETY PROVISIONS
Chapter 3 General Requirements
General regulations contained in Chapter 3, are intended to improve premises safety for everyone, including construction workers, tenants, operations and maintenance personnel, and emergency response personnel.
Chapter 4 Emergency Planning and Preparedness
Chapter 4 addresses the human contribution to life safety during emergencies. Continuous training and scheduled fire, evacuation and lockdown drills can be as important as the required periodic inspections and maintenance of built-in fire protection features. The level of preparation by the occupants also improves the emergency responders’ abilities during an emergency.
PART III—BUILDING AND EQUIPMENT DESIGN FEATURES
Chapter 5 Fire Service Features
CFC § 102.1 Medium relevance — show source text
The IFC sets forth minimum requirements for these and other hazards and contains requirements for maintaining the life safety of building occupants; protecting emergency responders; and limiting the damage to a building and its contents as the result of a fire, explosion or unauthorized hazardous material discharge.
As described, the IFC has many types of requirements for buildings and facilities. The applicability of these requirements varies. An understanding of the applicability of requirements, as addressed in Sections 102.1 and 102.2, is necessary. Section 102.1 addresses when the construction and design provisions are applicable, whereas Section 102.2 addresses when the administrative, operational and maintenance provisions are applicable. Generally, the construction and design provisions apply to only new buildings or existing buildings and occupancies as addressed by Chapter 11. The administrative, maintenance and operational requirements are applicable to all buildings and facilities, whether new or existing.
ARRANGEMENT AND FORMAT OF THE 2025 CFC
Before applying the requirements of the CFC, it is beneficial to understand its arrangement and format. The CFC, like other codes published by the ICC, is arranged and organized to follow sequential steps that generally occur during a plan review or inspection.
The CFC is organized into seven parts. Each part represents a broad subject matter and includes the chapters that logically fit under the subject matter of each part. It is also foreseeable that additional chapters will need to be added in the future as regulations for new processes or operations are developed. Accordingly, the structure was designed to accommodate such future chapters by providing reserved (unused) chapters in several of the parts. This will allow the subject matter parts to be conveniently and logically expanded without requiring a major renumbering of the CFC chapters.

Chapter 2 is the repository of the definitions of terms used in the body of the code. The user of the code should be familiar with and consult this chapter because the definitions are essential to the correct interpretation of the code and because the user may not be aware that a term is defined.
Chapter 3 Wildland-Urban Interface Areas.
Chapter 3 provides for the fundamental aspect of applying the code—the legal declaration and establishment of wildland-urban interface areas within the adopting jurisdiction, mapping of the area, periodic review and updates.
Chapter 4 Wildland-Urban Interface Area Requirements.
The requirements of Chapter 4 apply to all occupancies in the wildland-urban interface and pertain to all of the following:
Fire service access to the property that is to be protected, including fire apparatus access roads and off-road driveways.
Premises identification.
Key boxes to provide ready access to properties secured by gated roadways or other impediments to rapid fire service access.
Fire protection water supplies, including adequate water sources, pumper apparatus drafting sites, fire hydrant systems and system reliability.
Fire department access to equipment such as fire suppression equipment and fire hydrants.
Chapter 5 Special Building Construction Regulations.
The regulations in Chapter 5 establish minimum standards for the location, design and construction of buildings and structures based on construction within a Fire Hazard Severity Zone or a Wildland-Urban Interface (WUI) Area.
The construction provisions of Chapter 5 are intended to supplement the requirements of the California Building Code and Califor- nia Residential Code and address mitigation of the unique hazards posed to buildings by wildfire and to reduce the hazards of building fires spreading to wildland fuels. This is accomplished by requiring ignition-resistant construction materials.
Chapter 6 Fire Protection Requirements.
Chapter 6 contains additional requirements for development and construction in Local Responsibility Areas (LRA) designated as Very High Fire Hazard Severity Zones and areas designated by the State Fire Marshal as State Responsibility Areas (SRA). While many of these provisions are found in Title 14 and Title 19 of the California Code of Regulations, they are replicated here for the code user. The local jurisdiction has the authority to apply the same regulations to LRA when the regulations are adopted by local ordinance.
The requirements in this chapter reference the process for adoption of Very High Fire Hazard Severity Zones in the LRA; criteria for evaluating existing subdivisions that are at significant fire risk and are without an adequate secondary egress; and criteria for fire safety provisions required in the Safety Element of a city or county General Plan.

Population growth and the expanding urban development into traditionally nonurban areas have increasingly brought humans into contact with wildfires. According to the National Fire Protection Agency (NFPA), every year, wildfires burn across the United States and a growing number of people are living where wildfires are a real risk. In 2018 more than 58,000 fires burned nearly 9 million acres across the US. More than 25,000 structures were destroyed, including 18,137 residences and 229 commercial structures. California accounted for the highest number of structures lost in one state due to the number of significant fires, including the Mendocino Complex, Carr, Camp and Woolsey fires.
The IWUIC is a model code that is intended to be adopted and used supplemental to the adopted building and fire codes of a jurisdiction. The unrestricted use of property in wildland-urban interface areas is a potential threat to life and property from fire and resulting erosion. The IWUIC has as its objective the establishment of minimum special regulations for the safeguarding of life and

property from the intrusion of fire from wildland fire exposures and fire exposures from adjacent structures and to prevent structure fires from spreading to wildland fuels, even in the absence of fire department intervention.
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 are provided in a tiered manner commensurate with the relative level of hazard present.

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—Scope and Administration (Sections 101–102) and Part 2—Administration and Enforcement (Sections 103–117). Section 101 identifies which buildings and structures come under its purview and references other I-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 registered design professional, contractor and property owner.
Section 104 was revised for the 2024 edition of the IEBC. For complete information, see the Relocations table in the Preface of this code.
PART 1—SCOPE AND APPLICATION
SECTION 101—SCOPE AND GENERAL REQUIREMENTS
[A] 101.1 Title. These regulations shall be known as the Existing Building Code of [ NAME OF JURISDICTION ], herein-after referred to as “this code.”
[A] 101.2 Scope. The provisions of this code shall apply to the repair, alteration, change of occupancy, addition to and relocation of existing buildings.

Frequently asked questions
Can a jurisdiction adopt only some appendices or must it adopt them all?
Yes. Jurisdictions adopt appendices selectively by ordinance or by following a matrix adoption table; they may adopt an entire appendix, adopt it as amended, or adopt specific sections only. See the code’s matrix/adoption guidance and local adoption resolutions for examples.
If an appendix is adopted, does it override the body of the code?
No. Adopted appendices supplement or provide detailed procedures that operate alongside the body of the code. Where a conflict exists, adoption language and local ordinance drafting determine the interplay; always check the adopting ordinance and the CFC’s state‑adoption notes.
When should plan reviewers and inspectors consult appendices?
Consult appendices when the permitting authority’s adoption or local ordinance references them (for example, using Appendix D for detailed access geometry tied to §503), or when a project specifically relies on an appendix method or form (such as fire‑flow tables in Appendix B or HMMP forms in Appendix H). If the appendix hasn’t been adopted locally, treat it as guidance only.
