CRSC · California Referenced Standards Code

How is Part 12 organized (chapters, chapter-numbering like 12-3, 12-11A, etc.)?

Part 12 is the California Referenced Standards Code’s section of state-specific standards. Each citation starts with “12‑” (Part 12), then the chapter number (optionally a letter, e.g., 11A), and finally the section identifier. Chapters and sections may use hyphenated forms (12‑3‑1.1) or lettered/dotted forms (12‑11A.203); check the chapter heading and the table of contents to locate the exact text.

What the code requires — in plain English

Part 12 is a collection of referenced standards and state-specific standards organized into chapters identified by a “12-” prefix and, in some cases, lettered chapter identifiers (for example 12-11A). Individual requirements inside a chapter are shown as numbered sections (for example § 12-3-1.1) or decimal/period-style section references (for example § 12-11A.203). See the Part 12 table of contents and the chapter headings for examples of these formats in the code.

The single most important rule: read the prefix “12-” as “Part 12” first, then read the remainder as the chapter (with optional letter) and section — e.g., 12-11A.203 = Part 12 → Chapter 11A → Section 203.

Requirements in detail

High-level organization you will see in Part 12:

  • Part identifier: the leading “12-” marks “Part 12 — Referenced Standards.”
  • Chapter label: the next digits (and optional letter) identify the chapter. Examples: 12-3, 12-10-3, 12-11A, 12-13.
  • Section / subsection format: sections within chapters may use hyphenated grouping (e.g., 12-3-1.1) or DOT notation after a lettered chapter (e.g., 12-11A.203). Both are used in Part 12.

How to read the common formats (decision-relevant)

Dimension Format(s) you will see What it means (how to locate) Code Reference
Part prefix 12- Indicates the text is in Part 12 — Referenced Standards. Start here. TOC showing Part 12 headings CHAPTER 12‑…
Simple chapter 12-3 Chapter number 3 of Part 12 (chapter title and scope inside). Locate chapter heading, then look for sections. See SECTION 12‑3‑1—SCOPE and 12‑3‑1.1 (releasing systems for security bars) § 12‑3‑1.1.
Multi-part chapter (dash groups) 12-10-3 Indicates a chapter with multiple grouped parts (example: "CHAPTER 12‑10‑3 EXITS"). Read chapter header for the topic. Example: CHAPTER 12‑10‑3 EXITS in the Part 12 table of contents.
Lettered chapter 12-11A, 12-11B Letter appended to chapter number indicates a subdivision (often accessibility chapters 11A/11B). Use the lettered chapter then locate sections with dot notation or numbered subsections. CHAPTERS 12‑11A AND 12‑11B — BUILDING AND FACILITY ACCESS. Sections shown as 12‑11A.203, 12‑11A.206, etc.
Section within chapter 12-3-1.1 or 12-11A.203 Hyphenated forms (12‑3‑1.1) are used in some chapters; dotted forms (12‑11A.203) are used in lettered chapters. Both identify an enforceable text location. § 12‑3‑1.1 (scope for releasing systems) and § 12‑11A.203 (detectable warning products) are examples.
Reserved chapters “RESERVED” label A chapter listed in the TOC as RESERVED contains no current material; do not assume requirements exist there. Example: CHAPTER 12‑12 — RESERVED in the TOC.

Concrete code examples (controls you will actually see)

  • Releasing systems for security bars appear under SECTION 12‑3‑1—SCOPE and include § 12‑3‑1.1 as the scope sentence for that standard.
  • Detectable warning & directional surface product approvals appear in CHAPTERS 12‑11A and 12‑11B, and the text references sections like § 12‑11A.203, § 12‑11A.206, § 12‑11A.209 (shape/color/resilience requirements and two‑year recertification).
  • Standards for insulating material are grouped in CHAPTER 12‑13 with article/section numbers such as § 12‑13‑1551 (application & scope), § 12‑13‑1557 (identification/labeling), § 12‑13‑1558 (inspections), and § 12‑13‑1559 (performance tests).

Exceptions & special cases

  • Lettered chapters (A, B, C, etc.) are common where the content parallels other codes (for example accessibility chapters 11A/11B). The notation changes the section reference style (you will see dotted section numbers following the letter). Always match the chapter-letter before locating sections.
  • “Reserved” chapters appear in the Part 12 TOC (for example CHAPTER 12‑12 — RESERVED). These are placeholders and contain no enforceable text; do not treat them as silent requirements.
  • Some chapters are long, sub-divided, or use multiple hyphen groups (e.g., 12‑10‑1, 12‑10‑2). Treat each hyphen group as part of the chapter identifier (not as separate “section digits”) and then find the numbered sections inside that chapter header.

Common mistakes

  • Misreading the prefix: treating a reference like “12‑11A.209” as Part 11 rather than Part 12 → Chapter 11A. Always read the leading “12‑” first.
  • Confusing hyphens and periods: hyphenated forms (12‑3‑1.1) and dotted lettered forms (12‑11A.203) both exist — don’t try to normalize them into a single pattern without checking the chapter heading.
  • Assuming a TOC line equals an enforceable test method: the TOC entry (e.g., CHAPTER 12‑13) tells you the subject; you must open the referenced sections (e.g., § 12‑13‑1551) to find the scope and requirements.

Worked example — how to interpret a reference and find the rule

You are given the citation: 12-11A.206.

Step 1 — parse: leading 12‑ = Part 12; 11A = Chapter 11A (the accessibility chapter under Part 12); .206 = section 206 in that chapter.

Step 2 — open CHAPTER 12‑11A in Part 12 TOC and locate section 206. The Part 12 table of contents lists CHAPTERS 12‑11A AND 12‑11B — BUILDING AND FACILITY ACCESS; the chapter text shows Sections 12‑11A.206 and 12‑11B.206. Section § 12‑11A.206 requires two‑year recertification of detectable warning products and directional surfaces. So the citation refers to the recertification requirement in the accessibility standards.

Numeric example (quick check): you find the TOC page that lists CHAPTER 12‑13 at page X and then open § 12‑13‑1551 to confirm this chapter’s scope and the list of insulating material types. That section enumerates which insulation types are covered (aluminum foil, polystyrene, cellulose, etc.).

  • CRSC § 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.

    SECTION 1110A—EXTERIOR ACCESSIBLE ROUTES

    1110A.1 General. When a building or portion of a building is required to be accessible or adaptable, an accessible route shall be provided to all portions of the building, accessible building entrances and between the building and the public way. The accessible route shall be the most practical direct route and to the maximum extent feasible, coincide with the route for the general public and building residents.

    Exterior accessible routes shall be provided as follows:

    1. At least one accessible route within the boundary of the site shall be provided from public transportation stops, accessible parking and accessible passenger loading and unloading zones, and public streets or sidewalks to the accessible building entrance they serve. Where more than one route of travel is provided, all routes shall be accessible.

    2. At least one accessible route shall connect accessible buildings, facilities, elements and spaces that are on the same site. Acces- sible routes shall be provided between accessible buildings and accessible site facilities when more than one building or facility is located on a site.

    3. At least one accessible route shall connect accessible building or facility entrances with all accessible spaces, elements and covered multifamily dwelling units.

    4. An accessible route shall connect at least one accessible entrance of each covered multifamily dwelling unit with exterior spaces and facilities that serve the dwelling unit.

    5. Where elevators are provided for vertical access, all elevators shall be accessible. See Section 1124A.

    Note: If the slope of the finished grade between covered multifamily dwellings and site arrival points, public use or common use facilities (including parking) exceeds 1 unit vertical in 12 units horizontal (8.33-percent slope), or where other physical barriers (natural or artificial) or legal restrictions, all of which are outside the control of the owner, prevent the installation of an accessible route, an acceptable alternative is to provide access by a vehicular route, provided:

    1. There is accessible parking on an accessible route for at least 2 percent of the covered multifamily dwelling units, and

    2. Necessary site provisions such as parking spaces and curb ramps are provided at the public use or common use facility.

    1110A.2 Signs. At every primary public entrance and at every major junction where the accessible route diverges from the circulation path along or leading to an accessible route, entrance or facility, there shall be a sign displaying the “International Symbol of

    SECTION 1117A—GENERAL REQUIREMENTS FOR ACCESSIBLE ENTRANCES, EXITS, INTERIOR ROUTES OF TRAVEL AND FACILITY ACCESSIBILITY

    Note: In addition to provisions of this division, interior routes of travel that provide access to, or egress from, buildings for persons with disabilities shall also comply with Chapter 10.

    1117A.1 General. When buildings are required to be accessible, building facilities shall be accessible as provided in this division. Where specific floors of a building are required to be accessible, the requirements of this division shall apply only to the facilities located on accessible floors.

    1117A.2 Primary entrances and exterior exit doors. All primary entrances and exterior ground floor exit doors to buildings and facili- ties on accessible routes shall be accessible to persons with disabilities.

    1117A.3 Separate dwelling unit entrances. When a ground-floor dwelling unit of a building has a separate entrance, each such ground-floor dwelling unit shall be served by an accessible route, except where the terrain or unusual characteristics of the site prohibit an accessible route (see Section 1150A for site impracticality tests).

    1117A.4 Multiple entrances. Only one entrance to covered multifamily buildings is required to be accessible to any one ground floor of a building, except in cases where an individual dwelling unit has a separate exterior entrance. Where the building contains clusters of dwelling units with each cluster sharing a different exterior entrance, more than one entrance may be required to be accessible, as determined by analysis of the site. In every case, the accessible entrance shall be on an accessible route to the covered dwelling units it

    serves.

    1117A.5 Entrances from parking structures, tunnels or elevated walkways. Where direct access for pedestrians is provided from a parking structure to a building or facility, each direct access to the building or facility entrance shall be accessible.

    Where direct access for pedestrians is provided from a pedestrian tunnel or elevated walkway to a building or facility, all entrances to the building or facility from each tunnel or walkway shall be accessible.

    SECTION 1118A—EGRESS AND AREAS OF REFUGE

  • CRSC § 1104A.2 Medium relevance — show source text

    (In this case,_ those dwelling units on the ground floor served by an elevator and at least one of each type of public- and common-use areas, would be subject to these requirements.) 2. Elevator building. When a building elevator or elevators are provided as a means of access to dwelling units other than dwell- ing units on a ground floor (see Section 1104A.2), the building is an elevator building. All dwelling units become covered multifamily dwellings in that building. The elevator in that building must provide accessibility to all dwelling units in the build- ing, regardless of the slope of the natural terrain. For multistory dwelling units in buildings with one or more elevators, see Section 1102A.3.2.

    Note: Where a building elevator is provided only as means of creating an accessible route to covered multifamily dwelling units on a ground floor, the building is not considered to be an elevator building, only dwelling units located on the ground floor shall be required to comply with this chapter. 3. Elevated walkway. When an elevated walkway is planned between a building entrance and a vehicular or pedestrian arrival point and the planned walkway has a slope no greater than 10 percent (1 unit vertical in 10 units horizontal), the floor being served by the elevated walkway becomes a ground floor and accessibility to all dwellings on that ground floor is required.

    Note: Since the planned walkway meets the 10 percent slope criterion, it is required to provide an accessible route to the entrance and the slope of the walkway must be reduced to 1 unit vertical in 12 units horizontal (8.33 percent slope) maximum.

    1106A.2 Site impracticality. For tests to determine site impracticality due to terrain considerations in nonelevator buildings, see Section 1150A.

Frequently asked questions

How can I tell whether a Part 12 reference uses hyphens or periods?

Look at the chapter heading. Chapters without lettered suffixes often use hyphen grouping inside section headers (e.g., 12‑3‑1.1); lettered chapters (like 12‑11A) use a dot before the section number (e.g., 12‑11A.203). Always confirm at the chapter start.

If a TOC shows “CHAPTER 12‑12 — RESERVED,” does that mean a requirement exists there?

No — “RESERVED” means no current enforceable provisions in that chapter. Refer back to the code publisher for future updates.

Where do I find the scope for insulating material rules?

Open CHAPTER 12‑13 and read § 12‑13‑1551 for application and scope (it lists the insulation types covered).

Are detectable warning products subject to periodic recertification?

Yes — Part 12 requires detectable warning products and directional surfaces to be recertified every two years; see § 12‑11A.206.

If I see “12‑10‑3,” how do I find applicable sections?

Find CHAPTER 12‑10‑3 in the Part 12 TOC (topic: Exits) then open that chapter to read contained sections and tests (e.g., emergency operation tests referenced elsewhere in Chapter 12).
