Administration

Chapter 1 (Administration) of the California Residential Code explains scope, agency authority, permits, inspections and enforcement (see §§R101–R114).

Last reviewed: July 6, 2026

Overview

Chapter 1, Division II of the California Residential Code establishes the scope, application, administration and enforcement framework for one- and two‑family dwellings and townhouses — in short, how the CRC is applied and who enforces it. The division is organized around Sections §R101 and §R102 (scope and applicability) and the administration and enforcement provisions §R103–§R114, which set out authority, permits, inspections and enforcement procedures .

These provisions matter because they create the legal and procedural backbone for every residential project: appointment and powers of the building official, permit requirements, plan‑review and construction‑document rules, inspections, certificates of occupancy, and stop‑work/remedy powers (for example, §§R104–R110 and §R114). Chapter 1 is therefore where technical requirements from the rest of the CRC connect to due‑process and enforcement in the field .

    DIVISION II SCOPE AND ADMINISTRATION

    User notes:

    About this chapter: Chapter 1 Division II establishes the limits of applicability of this code and describes how the code is to be applied and enforced. Chapter 1 Division II is in two parts: Part 1—Scope and Application (Sections R101–R102) and Part 2—Administration and Enforcement (Sections R103–R114). Section R101 identifies which buildings and structures come under its purview and references other I-Codes as applicable. Standards and codes are scoped to the extent referenced (see Section R102.4).

    The one- and two-family dwelling 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 building official appointed by the authority having jurisdiction and also establish the rights and privileges of the design professional, contractor and property owner.

    Division II is not adopted by the Department of Housing and Community Development except where specifically indicated. Note: Specific sections of Chapter 1, Division II adopted by the State Fire Marshal will be indicated in the Matrix Adoption Table.

    PART 1—SCOPE AND APPLICATION

    SECTION R101—SCOPE AND GENERAL REQUIREMENTS

    R101.1 Title. These provisions shall be known as the Residential Code for One- and Two-family Dwellings of [ NAME OF JURISDICTION ], and shall be cited as such and will be referred to herein as “this code.”

    R101.2 Scope. The provisions of this code shall apply to the construction, alteration, movement, enlargement, replacement, repair, equipment, use and occupancy, location, removal and demolition of detached one- and two-family dwellings and townhouses not more than three stories above grade plane in height with a separate means of egress and their accessory structures not more than three stories above grade plane in height.

    Exception: The following shall be permitted to be constructed in accordance with this code where provided with an automatic sprinkler system complying with Section R309 :

    1. Live/work units located in townhouses and complying with the requirements of Section 508.5 of the California Building Code.

    2. Owner-occupied lodging houses with five or fewer guestrooms.

    3. A care facility with five or fewer persons receiving custodial care within a dwelling unit.

    4. A care facility with five or fewer persons receiving medical care within a dwelling unit.

    5. A day care facility for five or fewer persons of any age receiving care within a dwelling unit.

    R101.2.1 Appendices. Provisions in the appendices shall not apply unless specifically adopted.

    R101.3 Purpose. The purpose of this code is to establish minimum requirements to provide a reasonable level of safety, health and general welfare through affordability, structural strength, means of egress, stability, sanitation, light and ventilation, energy conservation and safety to life and property from fire and other hazards and to provide a reasonable level of safety to firefighters and emergency responders during emergency operations.

    SECTION R102—APPLICABILITY

    R102.1 General. Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall be applicable. Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern.

    It is important to understand that the IRC contains coverage for what is conventional and common in residential construction practice. While the IRC will provide all of the needed coverage for most residential construction, it might not address construction practices and systems that are atypical or rarely encountered in the industry. Therefore, the IRC contains several references to other codes either as an alternative to the provisions of the IRC or where the IRC lacks coverage for a particular type of structure, design, system, appliance or method of construction. In other words, the IRC is meant to be all inclusive for typical residential construction and it relies on other codes only where alternatives are desired or where the code lacks coverage for the uncommon aspect of residential construction. Of course, the IRC constantly evolves to address new technologies and construction practices that were once uncommon, but are now common.

    The IRC is unique in that much of it, including Chapters 3 through 9 and Chapters 34 through 43, is presented in an ordered format that is consistent with the normal progression of construction, starting with the design phase and continuing through the final trimout phase. This is consistent with the “cookbook” philosophy of the IRC.

    Arrangement and Format of the 2025 CRC

    The CRC is divided into nine main parts, specifically: Part I—Administrative, Part II—Definitions, Part III—Building Planning and Construction, Part IV—Energy Conservation, Part V—Mechanical, Part VI—Fuel Gas, Part VII—Plumbing, Part VIII—Electrical and Part IX—Referenced Standards. Parts IV through VIII of IRC are not adopted in California and replaced with references to appropriate parts of Title 24. The following provides a brief description of the content of each chapter and appendix of the CRC:

    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.

    Chapter 3 Building Planning.

    Chapter 3 provides guidelines for a minimum level of structural integrity, life safety, fire safety and livability for inhabitants of dwelling units regulated by this code. Chapter 3 is a compilation of the code requirements specific to the building planning sector of the design and construction process. This chapter sets forth code requirements dealing with light, ventilation, sanitation, minimum room size, ceiling height and environmental comfort. Chapter 3 establishes life-safety provisions including limitations on glazing used in hazardous areas, specifications on stairways, use of guards at elevated surfaces, window and fall protection, and rules for means of egress. Snow, wind and seismic design live and dead loads and flood-resistant construction, as well as solar energy systems are addressed in this chapter.
