Code	Edition	Adoption
CALGreen —	2025	California Green Building Standards Code (CALGreen), 24 CCR Part 11, 2025 edition. NO MODEL CODE BASE — CALIFORNIA-AUTHORED, STATEWIDE AND MANDATORY. Authority: California Building Standards Law, Cal. Health & Safety Code Div. 13 Pt. 2.5 (s.18901 et seq.); building standards adopted, approved, codified and published by the California Building Standards Commission. ADOPTING INSTRUMENT: BSC rulemaking file BSC 03/24 — Part 11 — 2024 Triennial Code Cycle, carried to the Commission meeting of 2024-12-17. READ FIRST-HAND THIS RUN: the file's Updated Informative Digest (BSC-03-24-UID-PT11, "UPDATED INFORMATIVE DIGEST FOR PROPOSED BUILDING STANDARDS", Gov. Code s.11346.9(b)), which states verbatim: "The California Building Standards Commission finds that NO REVISIONS have been made which would warrant a change to the Informative Digest contained in the Notice of Proposed Action for 2025 California Green Building Standards Code (Part 11, Title 24, California Code of Regulations)." That sentence is what ties file number BSC 03/24 to Part 11 and to the 2025 edition. PUBLICATION AND EFFECTIVE DATE, from the Commission's own 2025 Title 24 California Code Changes page, verbatim: the 2025 edition of Title 24 was "published July 1, 2025, and effective January 1, 2026"; the BSC CALGreen page carries the same date for "PART 11 — CALIFORNIA GREEN BUILDING STANDARDS CODE ... effective January 1, 2026". INSTRUMENT CHAIN IS ONE LINK SHORT AND I AM SAYING SO: I DID NOT READ THE ISOR OR THE FINAL EXPRESS TERMS FOR THIS FILE. BSC-03-24-ISOR-PT11.pdf UNDER THE 2024-12-17 COMMISSION-MEETINGS PATH RETURNED A 404, AND BSC-03-24-FET-PT11.pdf AT THAT PATH RETURNED BINARY THE FETCHER COULD NOT PARSE. THE FET EXISTS AND IS THE DOCUMENT THAT MAKES THIS LAW; A HIGHER STANDARD READS IT. THE 2022 INTERVENING-CYCLE PART 11 FILE IS BSC 04/22 (ISOR at 2022-Intervening-Cycle/CAC/2023-02-08-Green/BSC-04-22-ISOR-PT11.pdf), WHICH CONFIRMS THE PART-11 ISOR NAMING PATTERN AND THAT THE CAC SUBFOLDER IS DATE-PLUS-"Green" — THE NEXT RUN SHOULD LOOK UNDER 2024-Triennial-Cycle/CAC/<date>-Green/, NOT UNDER Commission-Meetings/. · source ↗

Code Regs., Title 24) will be published July 1, 2025, with an effective date of January 1, 2026." INSTRUMENT CHAIN, STATED HONESTLY: the document read is the INITIAL Express Terms, which is a proposal. I did not read the Final Express Terms or confirm the Secretary of State filing. verified_at is set because this is the adopting board's own rulemaking document for this file and because the Commission's published 2025 Title 24 California Code Changes independently confirms Part 8 exists in the 2025 edition and was carried forward unchanged. A higher standard reads the FET. · source ↗
CMC —	2024	California Mechanical Code, 24 CCR Part 4 (2025 edition), based on the 2024 IAPMO Uniform Mechanical Code.

INSTRUMENT CHAIN, STATED HONESTLY: the ISOR is a proposal; I did not read the Final Express Terms, and I did not establish whether agencies other than the SFM also filed on Part 12 this cycle. verified_at is set because the ISOR is the filing agency's own rulemaking document and because the Commission's published 2025 Title 24 California Code Changes independently confirms Part 12 was carried forward into the 2025 edition unchanged. · source ↗
Energy —	2025	California Energy Code, 24 CCR Part 6 (2025 edition) - Building Energy Efficiency Standards for Residential and Nonresidential Buildings. NO MODEL CODE BASE: developed by the California Energy Commission under the Warren-Alquist Act, Cal. Pub. Res. Code ss. 25402 and 25402.1 (PRC Div. 15, s.25000 et seq.), and approved into Title 24 by the Building Standards Commission in the 2024 Triennial Code Adoption Cycle under H&SC Div. 13 Pt. 2.5 (s.18901 et seq.). CEC adoption September 2024. EFFECTIVE DATE, quoted verbatim from the Energy Commission's own page: "Buildings whose permit applications are applied for on or after January 1, 2026, must comply with the 2025 Energy Code." The edition value 2025 on this row is the CALIFORNIA LABEL YEAR, not a model base year - Part 6 has no model code underneath it and California adopts no edition of the IECC (see sibling row 142ff72c). · source ↗
IBC — International Building Code	2024	Cal. Health & Safety Code Div. 13, Pt. 2.5 (California Building Standards Law, sec. 18901 et seq.); HSC sec. 18928 (adoption of most recent model code edition within one year of publication) and HSC sec. 18934.5 (Commission shall adopt, approve, codify and publish building standards). Codified at Cal. Code Regs., tit. 24, pt. 2 (2025 California Building Code). BSC rulemaking BSC-05-24, 2024 Triennial Code Adoption Cycle; ISOR states: "BSC proposes to adopt the 2024 IBC, the most recent edition of the model code, for codification and effectiveness into the 2025 edition of the CBC." · source ↗
IECC — International Energy Conservation Code	NOT ADOPTED — California adopts NO edition of the International Energy Conservation Code, and never has. The statewide energy code is the CALIFORNIA ENERGY CODE (Building Energy Efficiency Standards for Residential and Nonresidential Buildings), 2025 edition, 24 CCR Part 6 with associated administrative regulations in Part 1, developed by the CALIFORNIA ENERGY COMMISSION under the Warren-Alquist Act and EFFECTIVE 2026-01-01 ("Buildings whose permit applications are applied for on or after January 1, 2026, must comply with the 2025 Energy Code"). *** THE NEGATIVE IS STRUCTURAL, NOT ADMINISTRATIVE: PART 6 HAS NO MODEL CODE UNDERNEATH IT AT ALL. The Building Standards Commission Guide to Title 24 (6th ed.) states it flatly: "Parts 1, 6, 8, 11 and 12 are not based on model codes. The contents of these parts are developed by state agencies and are California standards." The same guide names the model base of every part that has one (Part 2 = 2024 IBC; Part 2.5 = 2024 IRC; Part 3 = 2023 NEC; Part 4 = 2024 UMC; Part 5 = 2024 UPC; Part 7 = 2024 IWUIC; Part 9 = 2024 IFC; Part 10 = 2024 IEBC) and assigns Part 6 none. The IECC is not the base, not an alternate compliance path, and not referenced as an adopted standard. Authority is PUBLIC RESOURCES CODE ss. 25402 and 25402.1 — which direct the Energy Commission to PRESCRIBE standards, naming no model code and no publisher; contrast Health & Safety Code s.17922(a), the publisher-named enumeration that settles the California IPC negative (row b9439c75), which likewise does not name the IECC. CALIFORNIA CANNOT ACQUIRE AN IECC BY THE ORDINARY TRIENNIAL MECHANISM: THERE IS NO ADOPTION-BY-REFERENCE SLOT TO PUT IT IN. DO NOT RECORD ANY IECC EDITION FOR CALIFORNIA. See sibling row 7957ec83 (code_type Energy) for the affirmative record.	Cal. Pub. Res. Code ss. 25402 and 25402.1 (Warren-Alquist State Energy Resources Conservation and Development Act, PRC Div. 15, s.25000 et seq.) — the Authority and Reference notes printed on the standards themselves read "Sections 25402 and 25402.1, Public Resources Code", with further reference to ss. 25007, 25008, 25218.5, 25310, 25402.4, 25402.5, 25402.8 and 25943. Codified at Cal. Code Regs., tit. 24, pt. 6 (2025 California Energy Code) with associated administrative regulations in Part 1; approved into Title 24 by the California Building Standards Commission in the 2024 Triennial Code Adoption Cycle under H&SC Div. 13 Pt. 2.5 (s.18901 et seq.), CEC adoption September 2024, effective 2026-01-01. NO INSTRUMENT ADOPTS THE INTERNATIONAL ENERGY CONSERVATION CODE: Health & Safety Code s.17922(a) enumerates California's adopted model codes by publisher and does not name it, and PRC s.25402 names no model code or publisher at all. · source ↗
IFC —	2024 IFC	Cal. Health & Safety Code s.18928 (adoption of the most recent model code edition) and California Building Standards Law, H&SC Div. 13 Pt. 2.5 (s.18901 et seq.); State Fire Marshal authority H&SC s.13100 et seq., s.13143. Codified at Cal. Code Regs., tit. 24, pt. 9 (2025 California Fire Code). ADOPTING INSTRUMENT: BSC rulemaking file SFM 06/24 — Part 9 — 2024 Triennial Code Adoption Cycle. The ISOR (dated 2024-06-10) states verbatim: "The SFM is proposing to repeal the adoption by reference to the 2021 International Fire Code and incorporate and adopt by reference in its place the 2024 International Fire Code for application and effectiveness in the 2025 California Fire Code." Final Express Terms SFM-06-24-FET-PT9 approved at the Commission meeting of 2025-02-26 and filed with the Secretary of State; 2025 edition effective 2026-01-01. Intervening amendments in progress under SFM 03/25 (2025 Intervening Code Cycle), supplements effective 2027-07-01, which do NOT change the 2024 IFC base. · source ↗
IMC — International Mechanical Code	NOT ADOPTED — California has NO International Mechanical Code, in no edition, and never has. The statewide mechanical code is the CALIFORNIA MECHANICAL CODE, 2025 edition, 24 CCR Part 4, BASED ON THE 2024 IAPMO UNIFORM MECHANICAL CODE, adopted in the 2024 Triennial Code Adoption Cycle and EFFECTIVE 2026-01-01 (published 2025-07-01). ADOPTING-INSTRUMENT WORDS QUOTED VERBATIM FROM THE ISOR: the 2025 California Mechanical Code is "based upon the 2024 Uniform Mechanical Code of the International Association of Plumbing and Mechanical Officials (IAPMO)". THE PRIOR CYCLE IS NAMED IN THE SAME DOCUMENT AND CONFIRMS THE PUBLISHER IS STABLE ACROSS CYCLES, NOT A ONE-OFF: "the 2022 California Mechanical Code which is based upon the 2021 Uniform Mechanical Code". "INTERNATIONAL MECHANICAL CODE" AND "IMC" APPEAR NOWHERE IN THE ADOPTING RULEMAKING AND NOWHERE ON THE BUILDING STANDARDS COMMISSION'S OWN CODES PAGE — BOTH CHECKED THIS RUN, NEITHER ASSUMED. * CALIFORNIA IS A SPLIT-PUBLISHER STATE AND THIS ROW IS THE MECHANICAL HALF OF A PATTERN ALREADY EVIDENCED IN THIS TABLE. BUILDING/RESIDENTIAL/FIRE/EXISTING GO TO ICC (Parts 2, 2.5, 9, 10 on the 2024 IBC/IRC/IFC/IEBC); MECHANICAL AND PLUMBING GO TO IAPMO (Parts 4 and 5 on the 2024 UMC and 2024 UPC); ELECTRICAL GOES TO NFPA (Part 3, 2023 NEC); ENERGY IS CALIFORNIA'S OWN (Part 6, no model code at all — row 142ff72c). FOUR PUBLISHERS IN ONE STATE. NEVER INFER A CALIFORNIA MECHANICAL OR PLUMBING ANSWER FROM ITS BUILDING ROWS — THE STATE IS ON ICC FOR SOME PARTS AND EXPRESSLY NOT ON ICC FOR OTHERS, AND THE IMC/IPC NEGATIVES ARE STRUCTURAL, NOT ACCIDENTAL. * TITLE 24 PART MAP, READ FROM THE BSC'S OWN CODES PAGE AND RECORDED SO NO LATER RUN RE-FETCHES IT: Part 1 California Administrative Code; Part 2 Building; Part 2.5 Residential; Part 3 Electrical; Part 4 Mechanical (THIS ROW); Part 5 Plumbing; Part 6 Energy; Part 7 VACANT (formerly Elevator Safety Code); Part 8 Historical Building Code; Part 9 Fire; Part 10 Existing Building; Part 11 CALGreen; Part 12 Referenced Standards Code. NOTE PART 7 IS VACANT — A CITATION TO IT IS DEAD.	Cal. Health & Safety Code s.18928 (California Building Standards Law, H&SC Div. 13 Pt. 2.5, s.18901 et seq. — requires adoption by reference of a model code, with amendments, within one year after its publication; the ISOR recites this as its authority) and H&SC s.18934.5. ADOPTING INSTRUMENT: BSC rulemaking file SFM 01/24 — Part 4 — 2024 Triennial Code Adoption Cycle, Office of the State Fire Marshal, heard in the 2024-03-25 PEME code advisory committee. Codified at Cal. Code Regs., tit. 24, pt. 4 (2025 California Mechanical Code), based on the 2024 IAPMO Uniform Mechanical Code, superseding the 2022 CMC (2021 UMC). Selective adoption: UMC Chapters 12 and 15 NOT adopted. PUBLISHED 2025-07-01, EFFECTIVE 2026-01-01 — the effective date is taken from the Building Standards Commission's own Codes page, quoted verbatim: "The 2025 California Building Standards Code (Cal. Code Regs., Title 24) will be published July 1, 2025, with an effective date of January 1, 2026." That is a single statewide date for all of Title 24 and it matches the date already carried on the California IBC, IRC, IFC, IPC and Energy rows. *** COMPANION ROW: the CMC row (e3e95973) states the same 2024 UMC basis but is sourced only to the BSC's secondary "2025 Guide to Title 24" guidebook. THIS RUN HAS NOW READ THE ACTUAL RULEMAKING, SO THAT ROW CAN BE RE-SOURCED TO SFM-01-24-ISOR-PT4.pdf AND GIVEN ITS EFFECTIVE DATE, AMENDMENT COUNT AND CHAPTER CARVE-OUT AT ZERO FETCHES. · source ↗
IPC — International Plumbing Code	NOT ADOPTED — California has NO International Plumbing Code, in no edition, and cannot get one by agency rulemaking. The statewide plumbing code is the CALIFORNIA PLUMBING CODE, 2025 edition, 24 CCR Part 5, BASED ON THE 2024 IAPMO UNIFORM PLUMBING CODE, adopted in the 2024 Triennial Code Adoption Cycle and EFFECTIVE 2026-01-01. The Building Standards Commission's own Codes page assigns Title 24 parts by publisher and puts PARTS 4 AND 5 WITH IAPMO (Parts 1, 2, 2.5, 6, 8, 9, 10, 11, 12 with ICC; Part 3 with NFPA) — the ICC is nowhere near California plumbing. The state's own Guide to Title 24 (6th ed.) states it flatly: "Part 5 California Plumbing Code, based on the 2024 Uniform Plumbing Code". THE NEGATIVE IS STATUTORY, NOT MERELY ADMINISTRATIVE: Health & Safety Code s.17922(a) enumerates the model codes the department must adopt and names them WITH THEIR PUBLISHERS — Uniform Housing Code (ICBO), International Building Code (ICC), International Residential Code (ICC), UNIFORM PLUMBING CODE (IAPMO), Uniform Mechanical Code (IAPMO), National Electrical Code (NFPA), International Existing Building Code (ICC). THE INTERNATIONAL PLUMBING CODE IS NOT IN THAT LIST. California is an ICC state for building/residential/existing-building/fire and an IAPMO state for plumbing and mechanical — the split is written into the statute. See the sibling CPC row 99599d3c for the affirmative record. DO NOT RECORD ANY IPC EDITION FOR CALIFORNIA.	Cal. Health & Safety Code s.17922(a) (California State Housing Law — enumerates the model codes to be adopted by publisher; NAMES THE UNIFORM PLUMBING CODE, IAPMO; DOES NOT NAME THE INTERNATIONAL PLUMBING CODE); California Building Standards Law, H&SC Div. 13 Pt. 2.5 (s.18901 et seq.).

IWUIC —	2024	California Wildland-Urban Interface Code (CWUIC), 24 CCR Part 7 (2025 edition), based on the 2024 International Wildland-Urban Interface Code (ICC).

STATEMENT OF SPECIFIC PURPOSE, QUOTED VERBATIM: "The purpose of these proposed regulatory actions is to adopt by reference the 2024 edition of the International Wildland-Urban Interface Code (IWUIC), with California amendments, into the currently vacant California Code of Regulations (CCR), Title 24, California Building Standards Code (CBSC), Part 7." Authority: California Building Standards Law, Cal. Health & Safety Code Div. 13 Pt. 2.5 (s.18901 et seq.), s.18928; State Fire Marshal authority H&SC s.13100 et seq. Part 7 appears as "PART 7 - CALIFORNIA WILDLAND-URBAN INTERFACE CODE" in the table of contents of the Commission's own 2025 Title 24 California Code Changes (published 07/2025), independently confirming the part is live in the 2025 edition. Published 2025-07-01, effective 2026-01-01 per the BSC Codes page, verbatim: "The 2025 California Building Standards Code (Cal. Code Regs., Title 24) will be published July 1, 2025, with an effective date of January 1, 2026." INSTRUMENT CHAIN, STATED HONESTLY: I read the ISOR, which is a PROPOSAL. I did NOT read the Final Express Terms (SFM-08-24-FET-PT7) or confirm the Secretary of State filing. verified_at is set because the ISOR is the adopting agency's own rulemaking document for this file and because the Commission's published 2025 TOC independently shows the part as enacted - two official sources, neither secondary.
