CEBC · California Existing Building Code
What agency-specific exceptions or adoptions affect applicability of Chapter 3?
If your project is a normal existing building, follow one of the compliance paths in **§ 301.1** and the global Sections **§ 302–§ 309**. But if the property is state‑owned, a public school, a community college, or otherwise under a state agency (OSHPD, HCD, etc.), **§ 301.1** contains Exceptions that redirect you to specific seismic or agency rules (for example, **§§ 317–323** or Chapter 3A). Always verify jurisdiction using the Chapter 1 agency lists and the Matrix Adoption Tables, then read the actual section text cited in **§ 301.1** to confirm which sections apply.
Last reviewed: July 6, 2026
What the code requires — 2-4 sentences
Chapter 3 applies to the repair, alteration, change of occupancy, addition or relocation of existing buildings and requires those projects to comply with one of the compliance methods in § 301.1 (i.e., Section § 301.2, § 301.3 or § 301.4) and with the provisions of Sections § 302 through § 309 for all work regardless of method. § 301.1 also lists agency-specific exceptions that redirect certain state‑regulated buildings to the seismic standards in §§ 317–323 (state‑owned buildings, public schools, community colleges) or to other agency regulations. § 301.1 .
The short rule: follow § 301.1’s required compliance method (§ 301.2, § 301.3 or § 301.4) unless your building falls under an agency exception that requires following §§ 317–323 or another agency’s adopted rules. § 301.1
Requirements in detail
Which buildings are affected by agency-specific adoptions or exceptions
- The basic applicability and the three compliance choices are set out in § 301.1. § 301.1 indicates that Sections § 302–§ 309 apply to all work regardless of chosen compliance method. § 301.1 .
- The section then lists numbered Exceptions that are agency-specific and modify which seismic/rehabilitation provisions apply to particular state jurisdictions. Key exceptions in the text are Exception 1 (state‑owned structures) and Exception 2 (public school buildings). § 301.1 .
Decision dimensions (quick reference table)
| Decision dimension | Values / outcome you must check | Code Reference |
|---|---|---|
| Is the project an ordinary existing building not under a special state agency? | Use one of the methods in § 301.2, § 301.3 or § 301.4 and comply with §§ 302–309 | § 301.1 |
| Is the building state‑owned (including UC, CSU, Judicial Council)? | Seismic evaluation/retrofit minimums are the provisions in §§ 317–322 (may be locally adopted) — Exception 1 | § 301.1 Exception 1 |
| Is the building a public school under DSA‑SS jurisdiction? | Rehabilitation for public school buildings follows §§ 317–323 — Exception 2 | § 301.1 Exception 2 |
| Is the building regulated by OSHPD or other state agencies? | OSHPD-regulated structures use Chapter 3A and OSHPD notes (e.g., § 301A.1) and OSHPD may prohibit certain compliance options (for example, § 301.4 is not permitted by OSHPD) | See § 301.1 and § 301A.1 |
| Where to check whether a state agency adopts a section | Consult the matrix adoption tables at the front of each chapter — they indicate which agency adopts which sections | Code format & matrix guidance: § 1.1.11 and Matrix Adoption Tables |
Key textual points to note from the CEBC language
- The CEBC explicitly states the repair/alteration/addition/relocation work "shall comply with Section § 301.2, § 301.3 or § 301.4" and that Sections § 302–§ 309 apply irrespective of compliance method — § 301.1 .
- The CEBC includes agency acronyms and a Matrix Adoption Table to show which agencies adopt or do not adopt individual sections; those matrices are an interpretive tool but are not regulatory text themselves — see the code’s formatting and matrix note in § 1.1.11 and the chapter front matter .
- OSHPD uses a separate Chapter 3A for its regulated applications and may prohibit certain Chapter 3 options for OSHPD buildings (for example, § 301.4 not permitted by OSHPD) — see the OSHPD chapter leader and § 301A.1 .
Exceptions & special cases
- Exception 1 — Existing state‑owned structures: Buildings owned by the State (including University of California, California State University, Judicial Council) must comply with the minimum earthquake evaluation and retrofit standards in §§ 317–322 instead of following the general Chapter 3 compliance flow. § 301.1 Exception 1 .
- Exception 2 — Public school buildings (DSA‑SS): Public school buildings under DSA‑SS jurisdiction must follow §§ 317–323 for rehabilitation and earthquake evaluation where required by the California Administrative Code. § 301.1 Exception 2 .
- OSHPD‑regulated structures: OSHPD adopts CEBC provisions in Chapter 3A for its application list and explicitly disallows certain Chapter 3 options (e.g., § 301.4 is not permitted by OSHPD). See § 301.1 note and Chapter 3A adoption statements. § 301.1 .
- HCD (Housing and Community Development) jurisdiction: For buildings under HCD authority, the CEBC points such work toward California Code of Regulations, Title 25 (HCD regulations) in addition to CEBC Chapter 3 requirements. § 301.1 .
- Adoption matrix nuance: The Matrix Adoption Tables indicate whether a state agency adopts a particular section; always verify the matrix at the chapter front for agency-specific applicability. The matrix is a guide but the section language and agency notes are controlling. Matrix guidance: § 1.1.11 .
Common mistakes
- Assuming Chapter 3 applies identically to all buildings regardless of agency jurisdiction — the CEBC expressly redirects some buildings (state‑owned, public schools, community colleges, OSHPD facilities) to §§ 317–323 or agency‑specific chapters (3A). § 301.1 Exception 1 and Exception 2 .
- Relying solely on the Matrix Adoption Tables (front matter) without reading the section text and agency notes. The matrices help locate adoptions but are not a substitute for the section language; see § 1.1.11 .
- Overlooking OSHPD’s limitations: for OSHPD applications, Chapter 3A governs and OSHPD may prohibit certain Chapter 3 options (for example § 301.4 not permitted by OSHPD) — check § 301A.1 and the OSHPD adoption notes .
- Missing cross‑references to other agency regulations (HCD Title 25 for manufactured/movable homes, DSA requirements for schools/community colleges) when the CEBC points to other codes — see § 301.1 and agency notes .
Worked example — concrete scenario
Scenario: A public school (under the Division of the State Architect—Structural Safety) is proposing an alteration and seismic rehabilitation of a classroom wing.
- Identify jurisdiction: public school → DSA‑SS (per CEBC agency lists).
- Check applicability in CEBC § 301.1: public school buildings are covered by Exception 2, which directs seismic evaluation and rehabilitation to §§ 317–323 rather than the general Chapter 3 compliance flow. § 301.1 Exception 2 .
- Action: Follow the procedures and minimum standards in §§ 317–323 (for example you will use the seismic evaluation criteria, risk categories and retrofit thresholds in those sections) rather than trying to apply § 301.3 or § 301.4 compliance options that would otherwise apply for non‑DSA buildings. § 301.1 Exception 2 .
- Check for additional DSA‑SS administrative rules (referenced in Chapter 1, DSA adoption notes) and confirm whether local adoption or DSA guidance requires additional submittals. See the DSA adoption notes in Chapter 1 and Chapter 3 front matter .
In short: because this is a public school, you do not apply the generic Chapter 3 compliance path; you must use the school‑specific § 317–§ 323 path mandated by § 301.1 Exception 2. § 301.1 Exception 2 .
Related provisions
- § 301.1 — Administration; applicability and agency exceptions (includes Exceptions 1 & 2)

If you need, I can:
- Pull the exact matrix-adoption table rows for the agency that applies to your building type so you can see whether the State Fire Marshal, DSA or OSHPD adopted or omitted specific subsections; or
- Walk through a line-by-line applicability checklist for a specific building (identify agency, applicable Exceptions, and which sections to follow).

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.

3 PROVISIONS FOR ALL COMPLIANCE METHODS
User notes:
About this chapter: Chapter 3 explains the three compliance options for alterations and additions available in the code. In addition, this chapter also lays out the methods to be used for seismic design and evaluation throughout this code. Finally, this chapter clarifies that provisions in other I-Codes related to repairs, alterations, additions, relocation and changes of occupancy must also be addressed unless they conflict with this code. In that case, this code takes precedence.
SECTION 301—ADMINISTRATION
Frequently asked questions
Who decides if an Exception applies to my project?
The enforcing agency identified for your occupancy in Chapter 1 determines jurisdiction; then apply the Exception language in § 301.1 (for state‑owned, DSA schools, etc.) to see if §§ 317–323 or another agency chapter governs. § 301.1
Do the Matrix Adoption Tables control the law?
No — the matrix tables are a guide to which state agencies adopt particular sections; they help locate adoptions but you must read the actual section text and agency notes (see § 1.1.11). § 1.1.11
If my project is an OSHPD building, can I use § 301.4?
Not always. OSHPD regulates its projects under Chapter 3A and the CEBC notes that § 301.4 is not permitted by OSHPD for OSHPD applications; follow Chapter 3A and OSHPD adoption notes. § 301.1
Where do state‑owned university buildings point me?
State‑owned buildings (including UC/CSU/Judicial Council) are directed to the seismic evaluation and retrofit standards in §§ 317–322 by § 301.1 Exception 1. § 301.1 Exception 1
My building is under HCD authority — is Chapter 3 enough?
No. For HCD‑jurisdiction buildings, the CEBC directs compliance with California Code of Regulations, Title 25, in addition to the CEBC where noted — see § 301.1 and the HCD references. § 301.1
