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

California’s indoor heat standard, 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

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 (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 every California employer already must maintain.

Most of these inspections start with a complaint

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, 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

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

CompliantCA computed this analysis from the U.S. Department of Labor enforcement dataset (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, and our subsection-by-subsection walkthrough covers what it requires.

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