Cal/OSHA vs Federal OSHA: What Is Different in California

Cal/OSHA publishes statewide citation totals, and federal OSHA publishes its own, but neither publishes a comparison. This page is that comparison — CompliantCA’s analysis of the federal enforcement dataset that both flow into, covering the 78,088 citations issued on California inspections from January 2020 through December 2025 alongside the 637,242 issued everywhere else in the same window.

Three facts carry the argument. 24,938 California citations — 31.9% — cite a standard that has no federal counterpart. 56.0% of California inspections that produced any citation included at least one of them. And the single most cited standard in California is a written-program requirement, §3203, while the most cited standard in the rest of the country is a physical hazard, fall protection.

Why California can require more

California operates an approved State Plan under Section 18 of the Occupational Safety and Health Act. The statutory test is that a state plan must be “at least as effective as” federal OSHA. That sets a floor, not a ceiling: a state plan may adopt standards on hazards federal OSHA has never addressed.

The practical result is that “stricter” understates the difference. On several subjects there is no federal rule to be stricter than. Heat is the clearest case: California has regulated outdoor heat since 2005 and indoor heat since 2024, while federal OSHA’s heat rulemaking, docket OSHA-2021-0009, remains at the proposed stage — the most recent document in it extends a post-hearing comment period to October 30, 2025. No final rule appears in the Federal Register as of 2026-08-26.

The eight standards with no federal counterpart

Citations are counted per violation line item, excluding rows flagged deleted. Penalties are current penalties as retrieved 2026-08-21 and change as cases settle. Section numbers are grouped to the base section, so §3203(a) and §3203(a)(4) count together.

§3205 is no longer in force: §3205(a)(1) applied the section until February 3, 2025, and its recordkeeping subsection until February 3, 2026. Its citations, and those under §5199, are concentrated in 2021 and 2022. Excluding both, the California-only share is 22,390 citations, 28.7%.

Two of these are the same requirement in different orders. §3203 applies under the General Industry Safety Orders and §1509 under the Construction Safety Orders; both require a written Injury and Illness Prevention Program. Together they account for 13,666 citations, 17.5% of the California total.

The permit sections are a category federal OSHA does not have at all. §341 lists the activities that require a Cal/OSHA permit before work begins, and §461 covers permits to operate pressure vessels including air tanks. Federal OSHA issues no operating permits.

What the rest of the country gets cited for

The same dataset, the same window, all states except California.

Four of the five name a physical hazard or a piece of equipment. California’s most cited standard names a document.

California-only standards are cited often and penalized lightly

The eight standards account for 31.9% of California citations but 18.6% of California penalty dollars. The mean current penalty is $1,249 on a California-only standard against $2,556 on everything else.

That gap is consistent with what these standards are. A missing written program or an expired permit is documentary, and Cal/OSHA’s penalty regulation, 8 CCR §336, sets proposed penalties from the severity and probability of injury. A serious fall hazard scores higher than a missing document.

Where California is stricter rather than different

Several heavily cited California standards do have federal counterparts, and the difference is in the detail rather than the existence. These are worth checking against the federal version rather than assuming they match:

• §342, reporting work-connected fatalities and serious injuries, against 29 CFR 1904.39
• §5194, hazard communication, against 29 CFR 1910.1200
• §5144, respiratory protective equipment, against 29 CFR 1910.134
• §5204, respirable crystalline silica, against 29 CFR 1910.1053

Method

Computed by CompliantCA from the U.S. Department of Labor enforcement dataset, which records Cal/OSHA inspections as a state plan alongside federal OSHA inspections. The population is every violation line item with an issuance date from 2026-01-01 back through 2020-01-01, excluding rows flagged deleted, joined to its inspection to establish the state. California rows come from 27,251 inspections that produced at least one citation.

California and federal citations use different numbering systems — Title 8 section numbers against 29 CFR — so no automated match between them is possible. The mapping of California standards to “no federal counterpart” was made by subject, one section at a time, and each California section title was verified against dir.ca.gov on 2026-08-26.
