Where are referenced standards for temporary emergency uses listed?
Appendix E directs you to **Table E108.1** (see **§ E108.1**) for the exact standards (IBC, IFC, NFPA, etc.) that apply to temporary emergency uses; the Appendix defines a **temporary use** as under **180 days** and gives the code official authority to manage extensions and apply the listed standards.
Last reviewed: July 6, 2026
What the code requires — 2-4 sentences
The list of referenced standards used by Appendix E (Temporary Emergency Uses) is collected in § E108; the table that identifies each standard, its effective date/title and the Appendix E sections that rely on that standard is Table E108.1 (see § E108.1). The scope and intent for temporary emergency uses (including the 180‑day default for a temporary use) are set out in § E101, and Appendix E is permissive unless adopted or referenced by ordinance.
The single most important rule: refer to Table E108.1 in § E108.1 to find which external standard (for example, IBC, IFC or NFPA documents) applies to a given Appendix E requirement.
Key defined terms (first mention)
- EMERGENCY — an event declared by local, state or federal entities that temporarily overwhelms response capabilities.
- TEMPORARY USE — an activity established for less than 180 days (code official may grant extensions). 180 days is the important threshold in § E101.1.2.
Requirements in detail
Where the standards are listed
- The Appendix explicitly directs the user to Table E108.1 for all standards referenced in Appendix E. See § E108.1.
- Table E108.1 lists each standard acronym, the standard name and the sections of Appendix E that reference that standard (so you can trace which requirement invokes the standard).
How to use the table
- Find the Appendix E section (for example, E106.4.3 on fire protection evaluations) that governs the issue you are dealing with, then look up the standard listed in Table E108.1 to get the specific external standard to apply.
Decision table — decision-relevant dimensions and where to confirm them
| Decision-relevant dimension | Typical values / examples | Code Reference |
|---|---|---|
| Where to find the list of outside standards for Appendix E | Table E108.1 (Referenced Standards) | § E108.1 |
| Are Appendix E provisions mandatory statewide? | Not mandatory unless adopted by the jurisdiction (adopting ordinance) | Appendix E introductory note; § E101.1 context |
| Which standard controls fire-safety evaluations for emergency uses | NFPA 550—2017 is cited for fire protection evaluation in E106.4.3; IFC and CBC entries also appear in the table | Table E108.1 / § E106.4.3 and § E108.1 |
| Temporary use duration to watch for extension authority | Less than 180 days is a temporary use; code official can grant extensions when emergency continues past 180 days | § E101.1.2 |
| How standards are shown in the Appendix table | Standard acronym, standard name (with effective date) and the Appendix E sections that reference it | § E108.1 (Table E108.1) |
Examples of standards listed in Table E108.1 (non‑exhaustive)
- IBC—24 (International Building Code) — referenced by E106.3, E106.5.1.
- IFC—24 (International Fire Code) — referenced by multiple fire safety sections (E106.4 family, E107.x).
- IWUIC—24 (International Wildland‑Urban Interface Code) — referenced by tiny‑house / WUI provisions (E107.3.5).
- NFPA 550—2017 (Guide to the Fire Safety Concepts Tree) — used for fire protection evaluation in E106.4.3.
Exceptions & special cases
- Appendix E is explicitly advisory/optional unless the adopting jurisdiction adopts it by ordinance — do not assume automatic statewide applicability; always confirm local adoption. (Appendix preface and § E101.1).
- The 180‑day timeframe for a TEMPORARY USE is a guideline; the code authorizes the code official to grant extensions for demonstrated cause when an emergency continues. See § E101.1.2.
- Some Appendix E provisions point to other California codes (for example, the California Fire Code sections used for evacuation plans) — follow the cross‑references in the Appendix section and then consult Table E108.1 to find the exact external standard citation. See § E106.4.1 and § E108.1.
Common mistakes
- Treating Table E108.1 as optional: the Appendix lists the standards that Appendix E references; when Appendix E is adopted by the jurisdiction, those references identify enforceable external standards. See § E108.1.
- Missing the cross‑reference chain: users sometimes stop at Appendix language and do not follow the referenced code sections (for example, E106.4 points to California Fire Code sections for evacuation plans). Always follow the Appendix section to the external code and then to the standard in Table E108.1.
- Ignoring the local adoption status: assuming Appendix E applies automatically statewide — but Appendix E is not mandatory unless the adopting ordinance incorporates it. Check local adoption.
Worked example — concrete scenario with numbers
Scenario: A city repurposes a civic center as a temporary shelter/medical screening center following a disaster. The shelter will operate for an expected 150 days.
Step 1 — Is this a TEMPORARY USE?
- Yes — the planned duration is 150 days, which is less than 180 days so it meets the Appendix E definition of TEMPORARY USE in § E101.1.2.
Step 2 — Identify which Appendix E provisions apply (fire safety, means of egress, occupant loads).
- Suppose you must evaluate fire protection — E106.4 directs the code official to use E106.4.1–E106.4.5. E106.4.3 requires a fire‑protection evaluation using NFPA 550 where appropriate. Then consult Table E108.1 to confirm the NFPA reference and any other listed standards (e.g., IFC entries for evacuation plan procedures). § E106.4.3 and § E108.1 apply.
Step 3 — Apply structural/live‑load guidance if needed.
- If the temporary use increases floor live loads above those for the building’s original occupancy, § E106.3 allows the temporary use but requires posting of the approved live load (and references CBC Section 1607 for load magnitudes). Consult the IBC/CBC entry shown in Table E108.1 for the exact code citation that applies to load requirements.
Step 4 — Confirm local adoption and permit requirements.
- Verify that the jurisdiction has adopted Appendix E (or accepts its guidance) and submit permits as soon as practicable under § E105.1; consult Table E108.1 for the precise standards to be used in plan review.
Result: For a 150‑day temporary shelter, follow the Appendix E sections for fire safety and egress, perform evaluations using the standards identified in Table E108.1 (§ E108.1), and coordinate with the code official for any postings, drills, or additional fire protection measures.

CEBC § 102.4 Medium relevance — show source text
Chapter 14 is applicable to any building that is moved or relocated. This chapter is independent of any of the three compliance methods and focuses on the structural loads where the building is being relocated.
Chapter 15 Construction Safeguards.
Chapter 15 establishes specific regulations in order to minimize the risk to the public and adjacent property during construction. Additionally, this chapter addresses fire and life safety and means of egress during the construction process. This includes requirements for a site safety plan. This chapter is also consistent with Chapter 33 of the CBC and Chapter 33 of the California Fire Code (CFC).
Chapter 16 Referenced Standards.
Chapter 16 lists all of the product and installation standards and codes that are referenced throughout Chapters 1 through 15 and includes identification of the promulgators and the section numbers in which the standards and codes are referenced. As stated in Section 102.4, these standards and codes become an enforceable part of the code (to the prescribed extent of the reference) as if printed in the body of the code.
Appendix A Guidelines for the Seismic Retrofit of Existing Buildings.
Appendix A provides guidelines for upgrading the seismic resistance capacity of different types of existing buildings. It is organized into separate chapters which deal with buildings of different types, including unreinforced masonry buildings, reinforced concrete and reinforced masonry wall buildings, and lightframe wood buildings. This appendix includes its own referenced standards.
Appendix B Supplementary Accessibility Requirements for Existing Buildings and Facilities.
Chapters 11A and 11B of the CBC contain provisions that set forth requirements for accessibility to buildings and their associated sites and facilities for people with physical disabilities. Appendix B was added to address accessibility in construction for items that are not typically enforceable through the traditional building code enforcement process.
Appendix C Guidelines for the Wind Retrofit of Existing Buildings.
The purpose of Appendix C is to provide voluntary prescriptive alternatives for addressing the retrofit of buildings in high-wind areas. Currently, there are two chapters which deal with the retrofit of gable ends and the fastening of roof decks, Appendix Chapters C1 and C2, respectively. This appendix includes its own referenced standards.
Appendix D Board of Appeals.
Appendix D contains the provisions for appeal and the establishment of a board of appeals. The provisions include the application for an appeal, the makeup of the board of appeals and the conduct of the appeal process.
Appendix E Temporary Emergency Uses.
Appendix E is intended to provide guidance for designers, engineers, architects and fire and building officials on allowing temporary emergency uses of existing buildings with respect to the minimum code requirements. This appendix is a template or checklist that references the relevant code requirement of concerns.

Frequently asked questions
Where exactly do I look to find which standard applies to a particular Appendix E requirement?
Look at the Appendix E section that controls your issue (for example, E106.4.3 for fire protection evaluation), then open Table E108.1 listed in § E108.1 to find the standard (and effective date/title) that the Appendix references.
Does Table E108.1 give the full text of the external standards?
No — Table E108.1 identifies the standard (acronym, title, effective date) and the Appendix E sections that reference it; you must obtain the full standard text from the standards publisher. § E108.1 provides the list, not the content.
Is Appendix E automatically enforceable everywhere in California?
No — the Appendix is not mandatory unless specifically adopted by the jurisdiction (check the adopting ordinance). See the Appendix prefatory note and § E101.1.
If my temporary use will last longer than 180 days, what then?
The code gives the code official authority to grant extensions for demonstrated cause; the official must use judgement to continue temporary uses as the emergency requires (see § E101.1.2).
If Appendix E references the IFC or IBC, which version do I use?
Use the specific edition and effective date listed in Table E108.1 (see § E108.1), because the table ties each Appendix E reference to a particular standard edition.
