# The Indoor Heat Rule in Restaurants: The First 18 Months of Cal/OSHA Enforcement

California's indoor heat rule took effect in July 2024, and restaurants immediately became its most-cited industry: 66 of the first 236 citations — 28%. Nearly all of the restaurant citations are for two things a kitchen can fix on paper before anyone visits: the written plan and training. Most of the citing inspections began with a complaint.

California's indoor heat standard, [8 CCR §3396](/guides/8-ccr-3396/), took effect July 23, 2024. This page is CompliantCA's computation of its first 18 months of enforcement, from the federal enforcement data: of the **236 citations issued under §3396 through December 2025, 66 — 28% — landed on restaurant inspections** (NAICS 7225), more than any other industry. Add hotels and the rest of accommodation and food services, and the sector holds a third of all indoor-heat enforcement to date.

The concentration follows the standard's own trigger: an indoor work area at or above 82°F with employees present, a threshold a cook line reaches routinely.

## What restaurants actually get cited for {#what-gets-cited}

| §3396 subsection | Restaurant citations | Share |
|---|---|---|
| (i) Written Heat Illness Prevention Plan | 35 | 53% |
| (h) Training | 25 | 38% |
| (e) Assessment, records, and controls | 4 | 6% |
| (d) Cool-down areas | 2 | 3% |
| | **Total: 66** | **100%** |

**91% of restaurant indoor-heat citations are for the plan and the training** — the two obligations a kitchen can satisfy on paper before an inspector ever visits. Citations about physical conditions — the cool-down area, the temperature records, the engineering controls — are 6 of 66. The pattern matches [§3396 enforcement generally](/guides/8-ccr-3396/#citations) (58% plan, 27% training across all industries), with restaurants skewing even harder toward training.

The plan does not have to be a new document: §3396(i) allows it to live inside the [Injury and Illness Prevention Program](/guides/8-ccr-3203/) every California employer already must maintain.

## Most of these inspections start with a complaint {#complaints}

Of the **43 restaurant inspections that produced a §3396 citation, 34 began as complaint inspections** — an employee or someone else reported the workplace to Cal/OSHA. That is the restaurant pattern in general: [statewide, 54% of restaurant inspections start with a complaint](/guides/what-triggers-a-cal-osha-inspection/), the highest of any industry we've measured — and the indoor heat rule gave heat complaints a specific standard to be cited under. Since July 2024, a complaint about kitchen heat can produce a §3396 citation.

## Citations by month since the standard took effect {#trajectory}

Monthly counts are small and uneven — a March 2025 spike of 31, a May–June dip to 5 and 6 — with the largest months at the end: 27, 23, and 33 in October through December 2025.](/static/charts/ca-3396-citations-by-month.svg)

| Month | Citations | Month | Citations |
|---|---|---|---|
| Sep 2024 | 1 | May 2025 | 5 |
| Oct 2024 | 5 | Jun 2025 | 6 |
| Nov 2024 | 6 | Jul 2025 | 15 |

The monthly counts are small and uneven — but 2024's final months total 27 citations against 209 across 2025. Enforcement of a new standard grows as inspectors apply it routinely, and §3396's is growing: within 18 months it became the **#6 most-cited standard on California restaurant inspections** — ahead of standards that have existed for decades — behind the IIPP (660 restaurant citations 2020–2025), fire extinguishers (243), hazard communication (203), the now-expired COVID standard, and injury reporting. Penalties as they stand now average $1,208 per citation across all §3396 enforcement, with a $25,000 maximum; these figures may change as cases settle.

## Methodology {#methodology}

CompliantCA computed this analysis from the [U.S. Department of Labor enforcement dataset](https://dataportal.dol.gov/) (the OSHA Information System), which includes Cal/OSHA because California operates an OSHA-approved State Plan. Scope: §3396 citation line items issued from the standard's first citation (September 26, 2024) through December 2025, excluding citation records deleted in the source data; restaurants are NAICS 7225 on the inspection record, and the restaurant-standards ranking uses all citation line items on NAICS 7225 inspections issued 2020 through 2025. Citations are grouped to the first-level subsection. Trigger classifications use the inspection-type code on the inspection record. Penalty figures are the penalty as it stands now, after any appeals and settlements, as retrieved 2026-08-26. With 236 total citations, single-industry figures move as new cases arrive; this page will be updated as the window extends. The regulation's full text is at [dir.ca.gov/title8/3396.html](https://www.dir.ca.gov/title8/3396.html), and our [subsection-by-subsection walkthrough](/guides/8-ccr-3396/) covers what it requires.

A citation count says what inspectors cited, not what any employer must do — the standard itself says that.

## Frequently asked questions

### Does Cal/OSHA's indoor heat rule apply to restaurant kitchens?

Yes. 8 CCR §3396 applies to indoor work areas that reach 82°F while employees are present, in any industry — and a cook line reaches it routinely. Enforcement confirms the reach: restaurants (NAICS 7225) drew 66 of the 236 §3396 citations issued through December 2025, more than any other industry, per federal enforcement data.

### What does Cal/OSHA cite restaurants for under the indoor heat rule?

The paperwork, overwhelmingly. Of the 66 restaurant §3396 citations issued through 2025, 35 (53%) cite subsection (i), the written Heat Illness Prevention Plan, and 25 (38%) cite subsection (h), training — 91% between them. Citations for physical conditions — cool-down areas, measurement and controls — are 9%.

### How do indoor heat inspections start in restaurants?

Mostly with a complaint. Of the 43 California restaurant inspections that produced a §3396 citation through 2025, 34 began as complaint inspections — someone reported the workplace to Cal/OSHA. Statewide, 54% of restaurant inspections start with a complaint, the highest share of any industry we've measured.

### Is indoor heat enforcement growing?

Yes, within a young standard's first ramp: 27 citations in the last months of 2024, 86 in the first half of 2025, 123 in the second half. Within 18 months, §3396 became the #6 most-cited standard on California restaurant inspections.
