Interior Finishes

Chapter 8 of the CBC sets performance and testing rules (§801–§808) that control which interior finishes, floor coverings and decorative materials are allowed by occupancy and location.

Last reviewed: July 5, 2026

Overview

This area of the California Building Code (CBC) is Chapter 8 and governs interior wall, ceiling and floor finishes, decorative materials, trim, insulation and acoustical ceiling systems. Chapter 8 establishes performance- and test-based limits (flame‑spread, heat release, smoke development, critical radiant flux) so finishes do not unduly contribute to fire growth or smoke in an occupied building .

Key provisions include the scope and general rules at §801–§802; wall and ceiling finish classifications and test methods (NFPA 286 or ASTM E84 / UL 723) in §803; interior floor finish requirements and minimum critical radiant flux criteria in §804; combustible materials in Type I/II construction and trim/decorative material limits in §805–§806; plus insulation and acoustical ceiling rules at §807–§808. These sections specify when Class A/B/C finishes, noncombustible materials, or sprinkler‑based exceptions apply and reference the required test standards and labeling practices .

Practical focus for designers and plan reviewers: identify the occupancy and location, confirm the required class or test protocol for the assembly or covering, and verify test reports/labels and sprinkler exceptions where applicable — the CBC sets the performance criteria that determine what materials are permitted in each situation .

    2025 CALIFORNIA BUILDING CODE xiii

    on Jul 18, 2025 11:14 AM (CDT) THEREUNDER.

    Chapter 7 Fire and Smoke Protection Features.

    Chapter 7 provisions present the fundamental concepts of fire performance that all buildings are expected to achieve in some form. This chapter identifies the acceptable materials, techniques and methods by which proposed construction can be designed and evaluated against to determine a building’s ability to limit the impact of fire.

    Chapter 7A Materials and Construction Methods for Exterior Wildfire Exposure.

    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, California Wildland-Urban Interface Code, shall apply to buildings and structures located in the wildland-urban interface (WUI) or Fire Hazard Severity Zone.

    Chapter 8 Interior Finishes.

    Chapter 8 contains the performance requirements for controlling fire growth within buildings by restricting interior finish and decorative materials. The provisions of Chapter 8 require materials used as interior finishes and decorations to meet certain flame-spread index or flame-propagation criteria based on the relative fire hazard associated with the occupancy.

    Chapter 9 Fire Protection and Life Safety Systems.

    Chapter 9 prescribes the minimum requirements for active systems of fire protection equipment to perform the following functions: detect a fire, alert the occupants or fire department of a fire emergency, and control smoke and control or extinguish the fire. Generally, the requirements are based on the occupancy, the height and the area of the building, because these are the factors that most affect firefighting capabilities and the relative hazard of a specific building or portion thereof. This chapter parallels and is substantially duplicated in Chapter 9 of the CFC; however, the CFC Chapter 9 also contains periodic testing criteria that are not contained in the CBC. In addition, the special fire protection system requirements based on use and occupancy found in CBC Chapter 4 are duplicated in CFC Chapter 9 as a user convenience.

    Chapter 10 Means of Egress.

    The criteria in Chapter 10 regulating the design of the means of egress system are established as the primary method for protection of occupants by allowing timely relocation or evacuation. Both prescriptive and performance language is utilized for determination of a safe exiting system. It addresses all portions of the means of egress system (i.e., exit access, exits and exit discharge) and includes design requirements as well as provisions regulating individual components. The requirements detail the size, arrangement, number and protection of means of egress components. The means of egress protection requirements work in coordination with other sections of the code, such as protection of vertical openings (see Chapter 7), interior finish (see Chapter 8), fire suppression and detection systems (see Chapter 9) and numerous others, all having an impact on life safety. Chapter 10 of the CBC is duplicated in Chapter 10 of the CFC; however, the CFC contains one additional section on the maintenance of the means of egress system in existing buildings.

    Chapter 11 Reserved.

    Chapter 11A Housing Accessibility. Chapter 11B Accessibility to Public Buildings, Public Accommodations, Commercial Buildings and Public Housing.

    Verify compliance with accessibility provisions. In order to be considered as accessible, buildings and their individual elements must comply with the applicable scoping and technical provisions of Chapter 11A and/or Chapter 11B.

    7 ALTERATIONS—LEVEL 1

    User notes:

    About this chapter: Chapter 7 provides the technical requirements for those existing buildings that undergo Level 1 alterations as described in Section 603, which includes replacement or covering of existing materials, elements, equipment or fixtures using new materials for the same purpose. This chapter, similar to other chapters of this code, covers all building-related subjects, such as structural, mechanical, plumbing, electrical and accessibility as well as the fire and life safety issues when the alterations are classified as Level 1. The purpose of this chapter is to provide detailed requirements and provisions to identify the required improvements in the existing building elements, building spaces and building structural system. This chapter is distinguished from Chapters 8 and 9 by involving only replacement of building components with new components. In contrast, Level 2 alterations involve more space reconfiguration, and Level 3 alterations involve more extensive space reconfiguration, exceeding 50 percent of the building area.

    SECTION 701—GENERAL

    701.1 Scope. Level 1 alterations as described in Section 602 shall comply with the requirements of this chapter. Alterations to historic buildings and structures shall comply with Part 8, Title 24, C.C.R.

    701.2 Conformance. An existing building or portion thereof shall not be altered such that the building becomes less safe than its existing condition.

    Exception: Where the current level of safety or sanitation is proposed to be reduced, the portion altered shall conform to the requirements of the California Building Code .

    [BS] 701.3 Flood hazard areas. In flood hazard areas, alterations that constitute substantial improvement shall require that the building comply with Section 1612 of the California Building Code, or Section R306 of the California Residential Code, as applicable.

    SECTION 702—BUILDING ELEMENTS AND MATERIALS

    702.1 Interior finishes. Newly installed interior wall and ceiling finishes shall comply with Chapter 8 of the California Building Code .

    702.2 Interior floor finish. New interior floor finish, including new carpeting used as an interior floor finish material, shall comply with Section 804 of the California Building Code .

    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

    The requirements of Chapter 5 apply to all buildings and occupancies and pertain to access roads, access to building openings and roofs, premises identification, key boxes, fire protection water supplies, fire command centers, fire department access to equipment, and in-building emergency responder communication system coverage.

    Chapter 6 Building Services and Systems

    Chapter 6 provides a more systematic view of building systems and services as they relate to potential safety hazards and when and how they should be installed.

    Chapter 7 Fire and Smoke Protection Features

    The maintenance of assemblies required to be fire-resistance rated is a key component in a passive fire protection philosophy. Chapter 7 sets forth requirements to maintain required fire-resistance ratings of building elements and limit fire spread. Section 701 addresses the basics of what construction elements such as fire barriers and smoke barriers need to be maintained as well as defining the owner’s responsibility. Sections 703 through 708, deals with various fire and smoke protection features that must also be maintained.

    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.

    Class A = Flame spread index 0–25; smoke-developed index 0–450.

    Class B = Flame spread index 26–75; smoke developed index 0–450.

    Class C = Flame spread index 76–200; smoke-developed index 0–450.

Frequently asked questions

What test standards classify wall and ceiling finishes?

Wall and ceiling finishes are classified by NFPA 286 acceptance criteria or by ASTM E84 / UL 723 flame‑spread and smoke‑developed indices (Class A, B or C) as specified in Section §803 of the CBC .

When are Class I (Class I/II) floor coverings required?

Section §804 requires minimum critical radiant flux performance for floor coverings in stairways, ramps, exit passageways, corridors and areas open to corridors; the code also allows sprinkler‑based exceptions where an automatic sprinkler system is provided throughout the building .

Can combustible materials be used as interior finish or trim?
