CRSC · California Referenced Standards Code

Where are laboratory animal quarters standards published in the CRSC?

Q: Where exactly in the CRSC is the laboratory animal quarters standard adopted?

The adoption is in Sec. 12‑4A‑101 of Part 12 (Standard 12‑4A‑1): the CRSC requires laboratory animal quarters to comply with Chapter IV of the Guide for Care and Use of Laboratory Animals (DHEW Pub. No. 85‑23, Revised 1985).

Q: Can I use a more recent edition of the Guide?

The CRSC text explicitly cites the 1985 revised edition (DHEW Pub. No. 85‑23). Using a different edition requires acceptance by the enforcing authority; the CRSC language itself references the 1985 revised publication. § 12‑4A‑101 .

California’s CRSC adopts federal guidance for laboratory animal quarters: **§ 12‑4A‑101** requires compliance with Chapter IV of the DHEW Guide (85‑23, Revised 1985); the CRSC references the Guide rather than reproducing technical specs, so plans must show how Guide provisions are met. file

What the code requires — plain English

The California Referenced Standards Code (CRSC) requires that laboratory animal quarters comply with the external guidance document Chapter IV, “Guide for Care and Use of Laboratory Animals,” U.S. Department of Health, Education and Welfare, Publication Number 85‑23, Revised 1985 — this is the single controlling rule in the CRSC: § 12‑4A‑101.

The most important rule: laboratory animal quarters in California must be designed and operated to meet the requirements found in Chapter IV of the federal Guide (as adopted by the CRSC in § 12‑4A‑101).

Requirements in detail

Controlling text in the CRSC

The CRSC implements a single standard for this subject: Standard 12‑4A‑1. The mandatory phrase in the CRSC is Sec. 12‑4A‑101: laboratory animal quarters shall comply with the federal Guide, Chapter IV. § 12‑4A‑101 is the controlling CRSC provision.

What that means in practice

The CRSC itself does not reproduce the technical requirements (cage sizes, ventilation rates, sanitation details, etc.). Instead it points projects and enforcing agencies to the specified edition of the federal Guide. See § 12‑4A‑101.
The California Building Code (Title 24, Part 2) identifies the same subject area under Section 1236 and directs users to Part 12, Chapter 12‑4A / § 12‑4A‑101 for the detailed referenced standard. This links the building code enforcement path to the CRSC adoption.

Decision‑relevant summary table

Decision dimension	What the CRSC says / required action	Code Reference
Controlling standard to use	Use Chapter IV of the Guide for Care and Use of Laboratory Animals (U.S. DHEW Pub. No. 85‑23, Revised 1985).	§ 12‑4A‑101
Where it is referenced in CBC	CBC Section 1236 refers projects to Part 12, Chapter 12‑4A (laboratory animal quarters).	CBC § 1236 → § 12‑4A‑101
Adopting/enforcing agency	Adopted under the Department of Public Health (DPH) authority; enforcement typically through DPH and local health agencies as provided in the building/code adoption matrix.	CRSC Chapter header and CBC adoption notes; see DPH adoption details. file
What is not provided by CRSC	No numerical room sizes, cage dimensions, ventilation rates, or cleaning schedules are printed in the CRSC text — those technical specs are in the referenced Guide.	§ 12‑4A‑101

How to show compliance to plan check / inspector

Provide the edition of the Guide you used (Chapter IV of DHEW Pub. No. 85‑23, Revised 1985) and identify the specific Guide sections that apply to each lab space (e.g., housing, quarantine, sanitation).
Cross‑reference those Guide requirements to your plans and specifications (mechanical schedules, room finishes, cage schedules, cleaning protocols).
Because the CRSC adopts the Guide by reference (rather than printing the text), the plan submittal must demonstrate how the Guide’s requirements are met in the project documents. See § 12‑4A‑101.

Exceptions & special cases

The CRSC text for Chapter 12‑4A contains no listed exceptions or alternate compliance paths within the CRSC itself; it simply adopts the Guide. Any exceptions, variances, or newer editions must be handled through the normal code amendment or local authority approval procedures — the CRSC language (Sec. 12‑4A‑101) does not spell out exceptions.
If a later edition of the Guide is relied upon, obtain explicit acceptance from the enforcing agency (DPH/local health) because the CRSC text names the 1985 revised publication specifically. The CRSC adoption is to the 1985 revised edition. § 12‑4A‑101.

Common mistakes

Assuming numeric design criteria are printed in the CRSC: they are not — the CRSC references the external Guide for details. See § 12‑4A‑101.
Submitting plans that say “comply with CRSC” without documenting which Guide provisions (chapter/paragraph) were applied — inspectors will expect explicit cross‑references to the Guide and design calculations or schedules showing compliance.
Using a different edition of the Guide without approval — the CRSC explicitly adopts the 1985 revised edition in § 12‑4A‑101.

Worked example — applying the rule (process, not new technical numbers)

Scenario: A university is proposing a new animal housing room that will contain 10 primary enclosures for rodents.

Step‑by‑step (what CRSC requires you to do)

Identify the technical Guide provisions that govern the proposed room (Chapter IV of DHEW Pub. No. 85‑23, Revised 1985) that cover: primary enclosure minimum dimensions, ventilation/air changes, sanitation finishes, and handwashing/room entry controls. The CRSC requires adherence to that Guide by adoption in § 12‑4A‑101.
On your design drawings and specifications, tag each relevant Guide requirement (for example: “Guide Ch. IV, Section X — enclosure floor area requirement”) and show the project value (e.g., proposed cage footprint, room air changes per hour) so the reviewer can see the mapping. The CRSC does not itself list the numeric values — you must pull them from the Guide and show them in submittal documents.
Submit the plans to the enforcing agency (DPH or local health/code official identified under Part 2 adoption notes) and provide a compliance matrix that ties plan elements to Guide citations. CBC Section 1236 points plan reviewers to the CRSC adoption (Part 12 / Chapter 12‑4A).

Note: the numeric design values (for example cage floor area, minimum ACH, sink counts) are not stated in the CRSC. You must quote and apply the Guide’s numbers in the submittal. If you cannot locate the specific Guide language required, obtain the actual Guide text and cite the exact pages/paragraphs in your compliance matrix. § 12‑4A‑101.

Frequently asked questions

Where exactly in the CRSC is the laboratory animal quarters standard adopted?

The adoption is in Sec. 12‑4A‑101 of Part 12 (Standard 12‑4A‑1): the CRSC requires laboratory animal quarters to comply with Chapter IV of the Guide for Care and Use of Laboratory Animals (DHEW Pub. No. 85‑23, Revised 1985).

Does the CRSC list cage sizes, ventilation rates or cleaning schedules?

No — the CRSC does not print those technical numbers. The CRSC adopts the federal Guide by reference (see § 12‑4A‑101), so the technical details are in the referenced Guide, not in the CRSC text.

Which agency enforces the CRSC standard for lab animal quarters?

The CRSC standard is adopted under the Department of Public Health (DPH) authority; plan review and enforcement coordinate with DPH/local health as indicated in the building code adoption notes. See the CBC adoption notes and the CBC Section 1236 linkage to Part 12. file

Can I use a more recent edition of the Guide?

The CRSC text explicitly cites the 1985 revised edition (DHEW Pub. No. 85‑23). Using a different edition requires acceptance by the enforcing authority; the CRSC language itself references the 1985 revised publication. § 12‑4A‑101.

How do I show compliance on plans?

Provide the Guide edition and chapter/paragraph references, and create a compliance matrix mapping Guide requirements to the plans/specs (mechanical calculations, finishes, cage schedules). The building code’s Section 1236 points reviewers to the CRSC adoption for details. file
