Special Occupancies and Operations (chapters 20–41, 48–49)
Part IV (Chapters 20–41, 48–49) of the California Fire Code groups occupancy‑specific and operation‑specific fire safety rules that supplement the general CFC.
Last reviewed: July 6, 2026
Overview
Part IV of the California Fire Code collects the occupancy‑ and operation‑specific requirements that don’t fit in the general safety or building‑design chapters — specifically Chapters 20 through 41 and 48–49 — and groups them into a single part for easier reference and enforcement. The code’s table of contents and Part IV designation make this clear: “Part IV—Chapters 20 through 41; 48 and 49: Special occupancies and operations.”
These chapters matter because they translate hazard‑specific experience into enforceable requirements: for example, Chapter 20 sets minimum fire‑safe practices for airports and aircraft hangars (see §2001.1), Chapter 33 prescribes fire safety and site‑safety plan requirements for construction and demolition sites (see §3301.1 and §3303.1), and Chapter 41 consolidates temporary heating and cooking controls (see §4105.1.1 and related provisions). Each chapter mixes prescriptive construction requirements, operational controls, and administrative duties so authorities and operators can manage the unique risks of those occupancies.
Part IV also includes occupancy chapters for specialized industries and uses — for example, motion‑picture production (Chapter 48) and storage or processing occupancies such as combustible fibers and distilled spirits — and the chapters are cross‑referenced with related CBC provisions and the code’s referenced standards to ensure consistent application.

Chapter 48 Motion Picture and Television Production Studio Stages, Approved Production Facilities and Production Locations
On July 23, 1982, a Bell UH-1 Iroquois helicopter crashed at Indian Dunes in Valencia, Santa Clarita, California, during the making of Twilight Zone: The Movie. The crash killed three people on the ground and injured the six helicopter passengers. Those killed were actor Vic Morrow and child actors Myca Dinh Le and Renee Shin-Yi Chen. The incident led to years of civil and criminal action and was responsi- ble for the introduction of new procedures and safety standards in the filmmaking industry.
Chapter 49 Requirements for Wildland-Urban Interface Fire Areas
Requirements for Wildland-Urban Interface Areas are now located in Part 7 of Title 24, California Wildland-Urban Interface Code. The provisions of Part 7, the California Wildland-Urban Interface Code shall apply to buildings and structures located in the wildland-urban interface (WUI) or Fire Hazard Severity Zone.
PART V—HAZARDOUS MATERIALS
Chapter 50 Hazardous Materials—General Provisions
Chapter 50 contains the general requirements for all hazardous chemicals in all occupancies. The general provisions of this chapter are intended to be companion provisions with the specific requirements of Chapters 51 through 67 regarding a given classification of hazardous material.
Chapter 51 Aerosols
Chapter 51 addresses the prevention, control and extinguishment of fires and explosions in facilities where retail aerosol products are displayed or stored. Requirements for storing aerosol products are dependent on the level of aerosol product, level of sprinkler protection, type of storage condition and quantity of aerosol products.
Chapter 52 Reserved for future use.
Chapter 53 Compressed Gases
Chapter 53 regulates the storage, use and handling of all flammable and nonflammable compressed gases, such as those that are used in medical facilities, air separation plants, industrial plants, agricultural equipment facilities and in systems such as carbon dioxide beverage dispensing and carbon dioxide enrichment. Where classified as a hazardous material, Chapter 50 would apply along with specific applications such as those used in welding and cutting (Chapter 35), cryogenic liquids (Chapter 55) and liquefied petroleum gases (Chapter 61).
Chapter 54 Corrosive Materials
Chapter 54 addresses materials whose primary hazard is corrosivity; that is, the ability to destroy or irreparably damage living tissue on contact. Although corrosive gases exist, most corrosive materials are solid or liquid and classified as either acids or bases (alkalis). These materials may pose a wide range of hazards other than corrosivity, such as combustibility, reactivity or oxidizing hazards, and must conform to the requirements of this code with respect to all known hazards.

Chapter 36 Marinas
Chapter 36 addresses the fire protection and prevention requirements for marinas. It was developed in response to the complications encountered by a number of fire departments responsible for the protection of marinas as well as fire loss history in marinas that lacked fire protection. Compliance with this chapter intends to establish safe practices in marina areas, provide an identification method for mooring spaces in the marina, and provide firefighters with safe operational areas and fire protection methods to extend hose lines in a safe manner.
Chapter 37 Combustible Fibers
Chapter 37 establishes the requirements for storage and handling of combustible fibers, including animal, vegetable and synthetic fibers, whether woven into textiles, baled, packaged or loose. Operations involving combustible fibers are typically associated with salvage, paper milling, recycling, cloth manufacturing, carpet and textile mills and agricultural operations, among others. The primary hazard associated with these operations is the abundance of materials and their ready ignitability.
Chapter 38 Reserved
Chapter 39 Processing and Extraction Facilities
Chapter 39 focuses on the plant processing, solvent based, and extraction of oils and fats from various plants, and cultivation and related activities. The processes used are not necessarily typical hazardous material processes and often the systems and equipment associated with such processes are not listed. This chapter provides the tools to appropriately enforce the CFC and provide an appropriate level of safety to meet the unique needs of the industry while providing the appropriate level of safety.
Chapter 40 Storage of Distilled Spirits and Wines
Chapter 40 provides specific requirements for the storage of distilled spirits and wines, including basic fire prevention requirements, fire protection features, storage configuration and signage. Additionally, in accordance with Section 307.1.1 of the CBC, these occupancies are not classified as a Group H occupancy. Instead, as listed in Sections 311.2 and 311.3 of the CBC, the storage of beverages that contain up to and including 20 percent alcohol are classified as a Group S-2 occupancy, and those that contain over 20 percent alcohol content are classified as a Group S-1 occupancy.
Chapter 41 Temporary Heating and Cooking Operations
Chapter 41 provides all requirements relative to temporary heating and cooking operations in a single chapter. Some of these provisions were originally found in Chapters 3, 6 and 31. This chapter is intended to facilitate consistent enforcement of temporary heating and cooking operations by making the requirements more straightforward.

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.

PART IV— SPECIAL OCCUPANCIES AND OPERATIONS
20 AVIATION FACILITIES
User notes:
About this chapter : Chapter 20 specifies minimum requirements for the fire-safe operation of airports, heliports and helistops. The principal nonflight operational hazards associated with aviation involve fuel, facilities and operations. Therefore, safe use of flammable and combustible liquids during fueling and maintenance operations is emphasized. Availability of portable Class B:C-rated fire extinguishers for prompt control or suppression of incipient fires is required.
SECTION 2001—GENERAL
2001.1 Scope. Airports, heliports, helistops and aircraft hangars shall be in accordance with this chapter.
2001.2 Regulations not covered. Regulations not specifically contained herein pertaining to airports, aircraft maintenance, aircraft hangars and appurtenant operations shall be in accordance with nationally recognized standards.
Frequently asked questions
Which chapters apply to construction sites and temporary jobsite operations?
Construction and demolition are covered primarily by Chapter 33 (Fire Safety During Construction and Demolition), which requires an approved site safety plan and other administrative controls (§3301.1; §3303.1). Temporary heating and cooking operations that may occur on jobsites are consolidated in Chapter 41 (see the portable heating/cooking appliance rules at §4102–4105).
How do these special‑occupancy chapters interact with the California Building Code and referenced standards?
Part IV CFC chapters supplement and coordinate with the CBC and the CFC’s referenced standards; the code’s table of contents and correlation notes explain those relationships and direct users to parallel CBC chapters and referenced standards where applicable.
Where can I find which sections the State Fire Marshal adopted or which agency adopts a specific chapter?
The CFC includes matrix adoption tables and notes about CCR, Title 19 adoptions; those matrices and adoption notes identify which agencies adopt entire chapters or select sections (see the matrix/adoption material for Chapter 20 and related notes).
