CALGreen · California Green Building Standards Code (CALGreen)

How does the Matrix Adoption Table affect which referenced standards apply to my project?

If you’re deciding which referenced standards apply, first confirm the occupancy’s state agency (see § 103–106), then open the CALGreen chapter for that occupancy and read the Matrix Adoption Table at the chapter start — the Matrix tells you which sections that agency adopted (entire chapter, selected sections, or adopted‑as‑amended). The Matrix is an aid (not the regulation); the actual adopted section text and any amendments control whether a referenced standard is mandatory.

What the code requires — plain English (controlling §)

The Matrix Adoption Tables are a non‑regulatory, user‑aid that show which state agency adopts which parts of CALGreen or its referenced standards for particular occupancies and chapters. To determine which referenced standards apply to your project you must: identify the occupancy, identify the state adopting agency for that occupancy (see § 103–106), then read the Matrix Adoption Table at the start of the chapter that covers your occupancy to see what that agency adopted (entire chapter, specific sections, or adopted-as‑amended). The code repeatedly notes that the tables are an aid (not the regulatory text) and that agency authority and actual adopted sections are controlled by Chapter 1 agency listings and the adopted text.

The single most important rule: identify the agency with authority for your occupancy (Chapter 1 §§ 103–106), then use the Matrix Adoption Table at the beginning of the occupancy’s chapter to see which CALGreen sections and referenced standards that agency actually adopts — the Matrix is an aid, not the regulation.

Note: I could not find the uploaded / retrievable text for § 601.1 in the files you provided. If you need the literal wording of § 601.1, please upload that page or confirm you want me to rely on the surrounding CALGreen guidance (above) instead. (I will not invent the text of § 601.1.)

Requirements in detail

Key defined terms (first mention bolded)

  • Matrix Adoption Table — the tabular adoption summary placed at the beginning of CALGreen chapters showing which adopting state agencies adopt the chapter or particular sections.
  • Adopting agency — the state agency (for example, [HCD], [DSA‑SS], [OSHPD]) that has statutory authority over a particular occupancy or building application and which may adopt CALGreen sections. See Chapter 1 guidance on agency acronyms.
  • Adopt entire chapter / Adopt only listed sections / Adopt as amended — matrix values that indicate the scope of an agency’s adoption for that chapter; the entry determines which CALGreen sections and therefore which referenced standards are binding under that agency’s authority.

Decision‑relevant dimensions (table)

Decision dimension (what you must decide/check) Possible values / how it affects which standards apply Code reference
Type of occupancy / application Residential, nonresidential, school, hospital, etc. — determines which chapter to consult See the “Effective Use of this Code” steps; locate chapter for occupancy § 103–106.
Adopting state agency Agency identified by occupancy (e.g., [HCD], [DSA‑SS], [OSHPD]) — only the adopting agency’s matrix entries control which sections it enforces See Chapter 1 legend and agency list; Matrix Adoption Tables show agency columns.
Matrix entry for that agency “Adopt entire chapter”, “Adopt entire chapter as amended”, “Adopt only listed sections”, or blank (not adopted). If adopted = referenced standards listed in those adopted sections apply as enforced by that agency. Matrix examples and column labels at chapter starts (Matrix Adoption Table).
“Adopted as amended” details If the matrix says “as amended,” you must read the amendment list in the section leaders — the amendment controls the actual mandatory language and any referenced standards. See chapter leaders / amendment notes in Matrix entries.
Local or voluntary tiers / exceptions Local amendments or voluntary tiers may change applicability. Voluntary measures are identified elsewhere and are not mandatory unless adopted locally. Voluntary tiers / guidance referenced in the code (e.g., §§ 304–306).

How the Matrix changes which referenced standards apply

  • The Matrix tells you whether the state agency enforces the chapter or specific sections; only the sections that the agency adopted (or adopted‑as‑amended) are binding for that occupancy under that agency. The referenced standards called out inside those adopted sections (and in the sections’ “Referenced standards” tables) therefore apply for your project under that agency’s enforcement.
  • The Matrix itself is non‑regulatory — it does not add or remove regulatory text. It helps you find which portions of the code (and their referenced standards) an agency chose to adopt. You must read the adopted section(s) for the actual mandatory language and citations to referenced standards.

Exceptions & special cases

  • The Matrix Adoption Tables are explicitly identified as nonregulatory aids; they are a guide only. The actual adoption status is in the chapter section leaders and Chapter 1 agency authorities. Do not treat the cell labels as substitutes for the adopted section text or the agency’s filing.
  • Some agencies mark sections with a special symbol (for example, †) to show they do not adopt them; you must respect those marks in the matrix and the chapter note. The state agency list/legend explains those symbols.
  • If an agency marks a chapter “Adopt entire chapter as amended,” you must read the amendment list (the amended sections are binding as amended). The amendments change which referenced standards (if any) are mandatory for that agency.
  • Voluntary measures (tiers) and agency‑specific policies: some measures in Chapter 5 (nonresidential) are voluntary to certain agencies (for example, DSA‑SS may treat some Chapter 5 mandatory measures as voluntary for schools/colleges). Check agency notes such as § 306.1.2 for how those apply.

Common mistakes

  • Reading the Matrix as the regulation. (Wrong.) The Matrix is an aid; the actual adopted text (and any amendments) controls.
  • Forgetting to confirm which state agency has authority for the occupancy — always confirm via § 103–106 before using the Matrix.
  • Missing “adopted as amended” notes — an “as amended” adoption often changes or removes specific referenced standards. Always read the amendment list.
  • Assuming a matrix cell that is blank means “no obligation.” A blank may mean the agency did not adopt that chapter/section; you still must check whether local jurisdiction or another agency has adoption or authority.

Worked example — step‑by‑step scenario

Scenario: You’re designing a new public K–12 school and want to know whether a referenced standard in Chapter 5 applies.

  1. Identify the occupancy and enforcing agency. Public schools and community colleges are typically under DSA‑SS authority — verify by checking § 103–106.
  2. Open the CALGreen chapter that covers schools (Chapter 5 / the nonresidential chapter) and find the Matrix Adoption Table at the chapter start. The table will have a column for DSA‑SS and rows showing “Adopt entire chapter”, “Adopt entire chapter as amended” or “Adopt only those sections”.
  3. Read the DSA‑SS entry:
    • If the matrix cell for DSA‑SS shows Adopt entire chapter, the Chapter 5 mandatory measures (and the referenced standards called out in those adopted sections) apply to your project.
    • If the matrix shows Adopt entire chapter as amended, click/locate the amendment list in the chapter leader; that list identifies which sections are changed — read those amended sections to see which referenced standards remain mandatory.
    • If the matrix shows DSA‑SS did not adopt certain sections (or marks them as not adopted), then those particular CALGreen mandatory measures (and their referenced standards) are not mandatory under DSA‑SS; they may be voluntary or enforced by a different agency or local jurisdiction. See § 306.1.2 about Chapter 5 measures that DSA‑SS may treat as voluntary for schools.
  4. Conclusion: The referenced standard applies to your project only if it is cited inside a CALGreen section that your adopting agency has adopted (or adopted‑as‑amended). The Matrix tells you where to look; the adopted section language (and any amendment) is the binding source.

Related provisions (pick these up when you’re working with matrices)

  • § 103–106 — agency authorities / how to identify the adopting agency for an occupancy.
  • § 304–306 — voluntary tiers and agency notes on voluntary measures (useful where the matrix shows non‑adoption by an agency).
  • Matrix Adoption Table examples at chapter starts — see the Matrix tables in Chapters 4, 5 and 8 for examples of how entries are laid out.
  • Chapter leaders and amendment lists — read the chapter leaders when the Matrix indicates “as amended” to find the amended language and any changes to referenced standards.
  • Section notes showing symbols (†, X, etc.) that indicate non‑adoption or special agency handling — watch for and read those notes.

    LEGEND FOR AGENCY ADOPTIONS

    Unless otherwise noted, state agency adoptions are indicated by the following banners in the section leaders: Department of Housing and Community Development: [HCD]

    California Building Standards Commission, CALGreen: [BSC-CG]

    Division of the State Architect, Structural Safety: [DSA-SS]

    Office of Statewide Hospital Planning and Development: [OSHPD 1, 2 & 4]

    See Chapter 1, Sections 103–106 for applications regulated by the respective state agencies.

    EFFECTIVE USE OF THIS CODE

    The format of this code is common to other parts of the California Building Standards Code and contains building standards applicable to occupancies which fall under the authority of different state agencies. Occupancies and applications under the authority of a specific state agency are identified in Chapter 1, Sections 103 through 106. Sections of this code which are applicable and adopted by each state agency are identified in the Matrix Adoption Tables located at the beginning of each chapter. The following outline is provided as a guide to establish which provisions are applicable to a specific occupancy.

    1. Establish the type of occupancy.

    2. Verify which state agency has authority for the established occupancy by reviewing the authorities list in Sections 103 through

    4. Once the appropriate agency has been identified, find the chapter which covers the established occupancy.

    5. The Matrix Adoption Tables at the beginning of Chapters 4 and 5 identify the required green building measures necessary to meet the minimum requirements of this code for the established occupancy.

    How to Distinguish Between Model Code Language and California Amendments

    To distinguish between model code language and the incorporated California amendments, including exclusive California standards, California amendments will appear in italics.

    [BSC] This is an example of a state agency acronym used to identify an adoption or amendment by the agency. The acronyms will appear at California Amendments and in the Matrix Adoption Tables. Sections 1.2 through 1.14 in Chapter 1, Division 1 of the Cali- fornia Building Code, explain the used acronyms, the application of state agency adoptions to building occupancies or building features, the enforcement agency as designated by state law (may be the state adopting agency or local building or fire official), the authority in state law for the state agency to make the adoption, and the specific state law being implemented by the agency’s adoption. The following acronyms are used in Title 24 to identify the state adopting agency making an adoption.

Frequently asked questions

How do I start — where do I look first?

Start by identifying the occupancy and then confirm which state agency has authority for that occupancy via § 103–106. Next, open the CALGreen chapter that covers your occupancy and consult the Matrix Adoption Table at the chapter start to see that agency’s adoption entries.

If the Matrix shows “Adopt only those sections” — which referenced standards apply?

Only the referenced standards that are cited in the listed adopted sections apply under that agency. You must open each listed section and read its “Referenced standards” table to see the exact standards.

Is the Matrix a regulation I can rely on by itself?

No. The Matrix is explicitly non‑regulatory and is an aid. The actual adopted sections (and any amendments) constitute the regulatory requirements; the Matrix tells you which sections to read.

What if a referenced standard is mandatory in the model code but my adopting agency didn’t adopt that section?

If the agency did not adopt the section that references that standard, the agency does not enforce that referenced standard for the occupancy under that agency’s authority. It may still be mandatory under another agency or a local amendment — confirm statutory authority and local adoptions.

You mentioned **§ 601.1** — do you have that text?

I could not find the uploaded / retrievable text for § 601.1 in the CALGreen files you provided. I relied on the CALGreen guidance about Matrix Adoption Tables and agency authority found in the chapter leaders and Chapter 1. If you need the exact wording of § 601.1, please provide that section or allow me to retrieve it.
