Title 24 · California Energy Code

Where are Part 6 administrative procedures (permits, enforcement, claims of exemption, appeals) specified?

The Energy Code (Part 6) delegates all administrative rules — permit rules, enforcement, exemptions, calculation approvals and appeals — to Title 24, Part 1, Sections 10‑101 through 10‑114; consult **§ 100.0(g)** and the Part 1 text or your local enforcing agency for the exact procedures.

What the code requires

The California Energy Code (Part 6) says that administrative requirements — including permit requirements, enforcement by the Commission, locally adopted energy standards, interpretations, claims of exemption, approved calculation methods, rights of appeal, and certain product certification/labeling rules — are set out outside Part 6 and are located in Title 24, Part 1, Sections 10‑101 through 10‑114. The controlling statement is in § 100.0(g) of the Energy Code.

The short plain-English rule: Part 6 sets the technical requirements; the administrative rules that tell you how to get permits, claim exemptions, appeal, or how the Energy Commission enforces Part 6 are specified in Title 24, Part 1, §§ 10‑101 — 10‑114.

Requirements in detail

Below are the decision‑relevant administrative topics (what to look up in Part 1) and where the Energy Code directs you to find them.

Decision question / dimension What matters for code users Code reference
Who sets the administrative procedures (permits, enforcement, appeals, exemptions)? The Energy Code directs users to Title 24, Part 1 for all administrative procedures governing Part 6. § 100.0(g) — see Energy Code; refers to Title 24, Part 1, §§ 10‑101–10‑114.
Permit requirements (when a permit is required) Permits for construction/installation regulated by Part 6 are handled under the administrative rules referenced in Part 1. (Local jurisdictions also have building/permitting duties under the building codes.) § 100.0(g) directing to §§ 10‑101–10‑114.
Enforcement authority and remedies Enforcement by the California Energy Commission (and the interplay with local enforcing agencies) is governed in the Part 1 administrative sections. § 100.0(g); see Title 24, Part 1 §§ 10‑101–10‑114 (text not in provided files).
Claims of exemption / exemption process The procedure for filing/deciding claims of exemption from Part 6 technical requirements is in the Part 1 administrative sections. § 100.0(g) referencing §§ 10‑101–10‑114.
Approved calculation methods & interpretations Which calculation methods are “approved” and how official interpretations are issued are delegated to the Part 1 administrative rules. § 100.0(g) referencing §§ 10‑101–10‑114.
Appeals processes & timing The Energy Code points appeals procedures to Part 1; local codes also commonly establish appeal boards and timelines. (See also appeals language found in other Title 24 code parts for examples of appeal filing periods.) § 100.0(g); consult §§ 10‑101–10‑114 for the Part 6-specific rules.

Notes on sources: The Energy Code statement pointing to Title 24, Part 1 is explicit in § 100.0(g). The uploaded files include the Energy Code text containing § 100.0(g) (which names §§ 10‑101 to 10‑114 as the administrative location) but the actual text of Title 24, Part 1, §§ 10‑101 – 10‑114 was not present in the provided files, so this article cannot quote those Part 1 sections verbatim.

How this interacts with local enforcing agencies

  • Local building departments enforce many construction and permit requirements; building/permitting duties and exemptions are described in the California Building and Residential Code administration sections (examples in the uploaded building/residential code files). See local permitting and exemptions guidance in the Building/Residential Code excerpts.
  • Local amendments and more restrictive local standards must follow statutory finding and filing rules (see California Existing Building Code discussion on local modifications and findings).

Exceptions & special cases

  • The Energy Code itself does not list the procedural details in Part 6 — it specifically delegates them. That means special or unusual administrative processes (for example, product labeling/certification, or energy‑calculation method approvals) are governed by the Part 1 text it cites (§ 100.0(g)).
  • Some other codes (fire code, building code) contain their own appeals and timing rules (for example, the Fire Code appendix shows a 20‑day appeal filing example) — these illustrate common administrative rules but are not the Part 6 administrative text. Do not assume those specifics apply to Part 6 until you verify Part 1 §§ 10‑101–10‑114 or local agency practice.

Common mistakes

  • Assuming Part 6 contains the permit and appeal procedures: the Energy Code intentionally delegates those rules to Title 24, Part 1 — the common mistake is reading Part 6 technical requirements but failing to consult Part 1 for how to comply administratively. See § 100.0(g).
  • Applying non‑Energy Code appeal timelines or processes (e.g., from other disciplines) to Part 6 without confirmation from Part 1 or the local enforcing agency. For example, other parts of Title 24 (or model codes) include appeal filing windows — verify the Part 1 text.
  • Not checking local amendments: jurisdictions may adopt local amendments (subject to required findings and filings); consult the local code adoption records and the Existing Building Code notes on local modifications.

Worked example

Scenario: A homeowner in a California city plans to replace all windows in a single‑family home and wants to know whether they need a permit, and whether an exemption process exists.

  1. Start with the Energy Code direction: § 100.0(g) says the administrative rules for permits and claims of exemption for Part 6 work are in Title 24, Part 1, §§ 10‑101–10‑114. That is the controlling cross‑reference to follow.
  2. Practically: contact the local building department and ask:
    • “Does the jurisdiction require a building or energy permit for window replacement, and do you apply the Part 6 administrative rules in Title 24 Part 1 (§§ 10‑101–10‑114)?”
    • Request the jurisdiction’s checklist/forms that implement those Part 1 procedures (permit forms, labeling/certification evidence for fenestration, exemption claim form if any). Local agencies implement Part 1 procedures when enforcing Part 6 technical requirements. Evidence that local enforcing agencies manage permits and appeals is present in the Building/Residential Code administration excerpts.
  3. If the homeowner is told “you can claim an exemption,” require the local agency to point to the specific subsection in Title 24, Part 1, §§ 10‑101–10‑114 they applied and to provide the written form and timeline for that claim (those are the sections the Energy Code points to in § 100.0(g)).

Because the actual text of Title 24, Part 1, §§ 10‑101 – 10‑114 was not included in the uploaded files, this example cannot reproduce the precise filing form, required evidence, or appeal time limits that the Part 1 language might specify. You must consult the Part 1 text (or the enforcing agency’s published procedures) for those exact details.

Frequently asked questions

Where exactly does the Energy Code say this?

The Energy Code states this in § 100.0(g): administrative requirements for Part 6 are specified in Title 24, Part 1, Sections 10‑101 to 10‑114.

Do Part 6 permit forms live in Part 6?

No — Part 6 contains technical rules. The administrative forms/procedures (permits, appeals, exemptions, enforcement processes) are located in Title 24, Part 1, §§ 10‑101–10‑114, per § 100.0(g).

Can a local jurisdiction change these administrative rules?

Jurisdictions may adopt local amendments or local processes subject to statutory requirements (findings/filings). For local modification rules and required findings see the Existing Building Code discussion on local modifications.

Where can I find the actual Part 1 text for §§ 10‑101–10‑114?

The official text of Title 24, Part 1, §§ 10‑101–10‑114 is published in the California Code of Regulations (Title 24, Part 1). The uploaded files provided the Energy Code cross‑reference but did not include the Part 1 section texts; consult the official CCR or your jurisdiction’s posted Part 1 chapter.

If I disagree with a local enforcement decision under Part 6, what should I do?

Follow the appeals procedure set out in the administrative rules referenced by § 100.0(g) (Title 24, Part 1, §§ 10‑101–10‑114). If a local appeals board is used, codes like the Residential and Existing Building Code describe creation and role of local appeals boards — contact your local building department for the exact appeal form/timeline.
