CRSC · California Referenced Standards Code
Which state agency authored a given Part‑12 chapter or standard?
To find which California state agency authored a Part‑12 chapter, open the chapter and read the STANDARD heading — the adopting agency is printed immediately under the standard title (the Part‑12 Cross‑Reference Table can be used as a non‑regulatory confirmation).
Last reviewed: July 6, 2026
What the code requires — plain English
The agency that “authored” a Part‑12 chapter or standard is stated in the standard’s heading: the chapter/standard header identifies the adopting agency (for example, STANDARD 12‑71‑1 — STATE FIRE MARSHAL). Look at the Part‑12 chapter or the Part‑12 Cross‑Reference Table to confirm the adopting agency. See § 12‑11A.205 (Independent entity / Access Compliance context) and the Part‑12 chapter heading and table entries for Chapter § 12‑71 for examples.
The single most reliable place to read who authored a Part‑12 standard is the standard’s own header (the “STANDARD 12‑XX‑#” line that names the state agency).
Requirements in detail
Where the authoring agency is shown
- Look at the top of the Chapter/Standard where the standard title appears (for example, STANDARD 12‑71‑1). The adopting agency is printed immediately beneath that title (for example, STATE FIRE MARSHAL for Chapter § 12‑71).
- Use the Part‑12 Cross‑Reference Table as an aid: it lists each Part‑12 chapter, the subject, the adopting agency, and associated Title 24 building standard references. The Cross‑Reference Table is explicitly described as a non‑regulatory aid.
Decision‑relevant dimensions (quick lookup table)
| Decision question | Where to look | Typical values you will see | Code Reference |
|---|---|---|---|
| Who is the adopting agency for a specific Part‑12 chapter? | Chapter/Standard heading (top of chapter) | Examples: STATE FIRE MARSHAL, DIVISION OF THE STATE ARCHITECT | See Chapter header for § 12‑71 and STANDARD 12‑71‑1 |
| Is the Cross‑Reference Table authoritative? | Part‑12 Cross‑Reference Table | Non‑regulatory; an aid only | Cross‑Reference Table note (Part 12) |
| When a chapter refers to product evaluation by an independent party, who selects that entity? | Relevant chapter text (access / detectable warnings example) | Independent entity (not‑for‑profit testing/certification organization) | § 12‑11A.205 (Independent entity) |
| If a chapter shows an agency name (e.g., DIVISION OF THE STATE ARCHITECT), is that the author? | Chapter/Standard heading | Yes — the agency named is the adopting agency | Example: 12‑16‑1 header shows DIVISION OF THE STATE ARCHITECT |
How to apply the rule (step‑by‑step)
- Open the Part‑12 chapter (e.g., Chapter 12‑71).
- Read the STANDARD heading at the top — the adopting agency name is printed directly below the standard title (that is the authoring agency).
- If you want confirmation or a quick look across chapters, consult the Part‑12 Cross‑Reference Table (non‑regulatory guide) which lists the adopting agency for each chapter.
- For product evaluation or access‑compliance program rules, read the specific section (for example, § 12‑11A.205 describes the Independent entity requirement).
Exceptions & special cases
- The Cross‑Reference Table is explicitly a non‑regulatory aid — it helps you find the agency but does not change who adopted the standard. Always prefer the chapter/standard heading when there’s a discrepancy.
- Some standards show agency program subdivisions (for example Division of the State Architect — Access Compliance). The name printed in the standard header is the adopting agency for that standard; program subdivisions clarify which office in the agency manages the standard. See the detectable‑warning sections and the DSA Access Compliance mention.
- Where a chapter incorporates another agency’s Title 24 provisions, that cross‑reference does not change the adopting agency for the Part‑12 standard itself — it only shows application elsewhere in Title 24. See the Cross‑Reference Table entries that pair chapters with Title 24 sections.
Common mistakes
- Mistake: reading the Cross‑Reference Table as the legal adoption — the table is non‑regulatory and only an aid. Always read the chapter header/standard for the authoritative adopting agency.
- Mistake: assuming chapter number or subject determines the agency (it may, but verify in the standard header). For example, some engineering device standards are DSA even if they interface with plumbing or mechanical Parts. See how 12‑16‑1 names DIVISION OF THE STATE ARCHITECT.
- Mistake: ignoring program notes inside a chapter — some chapters (e.g., detectable warnings) include procedural rules (such as Independent entity evaluation) that affect implementation; read those sections (see § 12‑11A.205).
Worked example — concrete scenario
You have Chapter 12‑71 (air‑filter testing) and need to know which state agency authored it.
Step 1 — open Chapter 12‑71 and read the standard heading. You will find STANDARD 12‑71‑1 followed immediately by the agency name STATE FIRE MARSHAL — that is the adopting agency. This is the primary indicator that the Office of the State Fire Marshal authored Chapter § 12‑71.
Step 2 — confirm in the Part‑12 Cross‑Reference Table: Chapter 12‑71 is listed with SFM in the adopting‑agency column. Use the Table only as confirmation; it’s an aid, not the adoption text.
Numeric detail (from the chapter): when you inspect Standard 12‑71‑100(a) you’ll see the test duct dimensions called out (for example 21 inches square and 13 1/2 feet long) — this demonstrates the chapter is technical and authored by the testing authority named in the header. Use the chapter text for technical details but read the header for the author.
Related provisions
- § 12‑11A.203 — Detectable warning products (see related requirements)
- § 12‑11A.204 — Directional surfaces (see related requirements)
- § 12‑11A.205 — Independent entity evaluation requirement (Access Compliance)
- § 12‑11A.206 — Two‑year recertification requirement for detectable warning products
- § 12‑71 — Air filters — standard header shows STATE FIRE MARSHAL (STANDARD 12‑71‑1)

All alterations, structurally connected additions and/or repairs to existing structures or portions thereof shall, at a minimum, be designed and constructed to resist the effects of seismic ground motions as provided in this section. The structural system shall be evaluated by a registered design professional and, if not meeting or exceeding the minimum seismic design performance requirements of this section, shall be retrofitted in compliance with these requirements.
Exception: Those structures for which Section 317.3 determines that assessment is not required, or for which Section 317.4 determines that retrofit is not needed, then only the requirements of Section 317.11 apply.
317.3 Applicability.
317.3.1 Existing state-owned buildings. [BSC, DSA-SS] For existing state-owned structures including all buildings owned by the University of California and the California State University, the requirements of Section 317 apply whenever the structure is to be retrofitted, repaired or modified and any of the following apply: 1. Total construction cost, not including cost of furnishings, fixtures and equipment, or normal maintenance, for the building exceeds 25 percent of the construction cost for the replacement of the existing building. The changes are cumulative for past modifications to the building that occurred after adoption of the 1995 California Building Code and did not require seismic retrofit.

PREFACE
This document is Part 12 of thirteen parts of the official triennial compilation and publication of the adoptions, amendments and repeal of administrative regulations to California Code of Regulations, Title 24, also referred to as the California Building Standards Code. This part is known as the California Referenced Standards Code.
The California Building Standards Code is published in its entirety every three years by order of the California legislature, with supplements published in intervening years. The California legislature delegated authority to various state agencies, boards, commissions and departments to create building regulations to implement the State’s statutes. These building regulations, or standards, have the same force of law, and take effect 180 days after their publication unless otherwise stipulated. The Califor- nia Building Standards Code applies to occupancies in the State of California as annotated.
A city, county, or city and county may establish more restrictive building standards reasonably necessary because of local climatic, geological or topographical conditions. Findings of the local condition(s) and the adopted local building standard(s) must generally be filed with the California Building Standards Commission (or other filing if indicated) to become effective, and may not be effective sooner than the effective date of this edition of the California Building Standards Code . Local building standards that were adopted and applicable to previous editions of the California Building Standards Code do not apply to this edition without appropriate adoption and the required filing.
The referenced standards contained in Part 12 are developed by the state agencies listed herein. The Part 12 Cross Reference Table herein identifies the state agency to which the standard applies, the subject of the standard and the provisions in other parts of Title 24 where the application of the standard is required.

Frequently asked questions
How can I be 100% sure which agency adopted a given Part‑12 standard?
Check the standard’s heading at the top of the chapter — the adopting agency is printed beneath the STANDARD title. Confirm with the Part‑12 Cross‑Reference Table as an aid.
Is the Cross‑Reference Table legally binding?
No. The Cross‑Reference Table is described as non‑regulatory and intended only as an aid to the code user; the chapter/standard heading is the authoritative place to read the adopting agency.
If a chapter references program offices (like DSA Access Compliance), does that change the adopting agency?
No — program office names clarify which office within the adopting agency administers the standard. The agency printed in the standard header is the adopting agency. See detectable warning sections for DSA/Access Compliance usage.
Where do I find product‑evaluation requirements (e.g., independent testing) tied to an adopting agency?
Those requirements appear in the chapter text (for example, § 12‑11A.205 describes the Independent entity evaluation requirement for detectable warning products).
If I find conflicting information between the chapter and the Cross‑Reference Table, which controls?
Rely on the chapter/standard heading and the chapter text; treat the Cross‑Reference Table as a non‑regulatory guide and confirm with the chapter header.
