If your company operates in multiple states, or if your corporate EHS standards were developed at an out-of-state headquarters, there’s something you need to know: compliance with federal OSHA does not mean compliance in California.
California runs its own occupational safety and health program, Cal/OSHA, under a State Plan approved by federal OSHA. Cal/OSHA enforces standards that meet or exceed federal requirements, and in several areas, California has requirements that don’t exist at the federal level at all.
What Makes California Different
Federal OSHA sets the floor. Cal/OSHA builds on it. In practice, this means California facilities are regulated under Cal/OSHA’s State Plan standards, which must be at least as effective as federal OSHA and are often more detailed, more prescriptive, or entirely California-specific.
The differences aren’t minor. They affect what programs you’re required to have, how you document them, and what inspectors expect to see.
Where California Goes Beyond Federal: A Few Examples
The full list of differences between Cal/OSHA and federal OSHA is extensive. These are some of the most common areas where we see California facilities fall out of compliance because their programs were built against federal standards.
Injury and Illness Prevention Program (IIPP). Every California employer is required to have a written IIPP under Title 8, Section 3203 of the California Code of Regulations. There is no equivalent federal OSHA requirement. This is the foundational safety document in California, the first thing a Cal/OSHA inspector asks for. It must include hazard identification, employee communication, training, workplace inspections, incident investigation, and hazard correction procedures. It must be tailored to your specific facility and operations, and it should be reviewed at least annually as a best practice. The regulation requires the program to be maintained and kept current as operations, hazards, or staffing change.
If your company’s corporate safety program was built around federal OSHA and doesn’t include a California-specific IIPP, your California facility has a gap in its most fundamental safety requirement.
Workplace Violence Prevention Plan (WVPP). Under SB 553, which took effect July 1, 2024, nearly all California employers, with limited exceptions, must maintain a written Workplace Violence Prevention Plan. This is a California-specific requirement with no federal equivalent. The plan must include procedures for identifying and evaluating workplace violence hazards, responding to incidents, and training employees. Violent incident logs must be maintained, and the plan must be reviewed annually.
Lockout/Tagout (LOTO). Both Cal/OSHA and federal OSHA require lockout/tagout programs, but the California standard (Title 8, §3314) is broader in scope. Cal/OSHA’s requirements cover a wider range of energy isolation scenarios and have specific provisions around group lockout procedures and periodic inspections that go beyond the federal standard. A facility running a LOTO program built on federal 29 CFR 1910.147 alone may not meet California’s additional requirements, a gap that becomes apparent when Cal/OSHA inspects.
Heat Illness Prevention. California has specific outdoor and indoor heat illness prevention standards that go beyond federal guidance. These require written procedures, access to water and shade, acclimatization protocols for new employees, and training, with specific temperature thresholds that trigger additional protections.
These are just examples. Cal/OSHA has California-specific standards or more stringent versions of federal standards across many program areas, from permissible exposure limits for certain chemicals to construction safety requirements to recordkeeping rules. The point isn’t to catalog every difference here, but to make clear that “we follow federal OSHA” is not a complete answer in California.
Enforcement Differences
Cal/OSHA conducts its own inspections, issues its own citations, and sets its own penalty amounts, independent of federal OSHA. A few differences that matter:
| Cal/OSHA | Federal OSHA | |
|---|---|---|
| Inspection authority | Cal/OSHA Division of Occupational Safety and Health (DOSH) | Federal OSHA Area Offices |
| Penalty structure | California sets its own penalty amounts under state law; some categories, including serious violations, carry higher maximums than federal OSHA | Federal OSHA penalty schedule |
| Recordkeeping | California-specific forms and reporting requirements in some areas | Federal OSHA 300 logs |
| Appeals process | Cal/OSHA Appeals Board | Federal OSHRC |
| Consultation program | Cal/OSHA Consultation Service (free, separate from enforcement) | Federal OSHA On-Site Consultation |

Why This Matters for Multi-State Companies
This is one of the most common compliance gaps we encounter. A company headquartered outside California develops EHS programs based on federal OSHA standards. Those programs are rolled out to every facility, including the California locations. From corporate’s perspective, the facilities are compliant. They have safety programs, training records, and documented procedures.
But the California facility doesn’t have an IIPP. Or it has one that was adapted from a federal template and doesn’t meet Cal/OSHA’s specific requirements. The Workplace Violence Prevention Plan doesn’t exist because it’s not required at corporate’s home state. Heat illness prevention wasn’t on the radar because the headquarters is in a state without California’s specific standards.
The gap isn’t visible from corporate because the programs look complete against a federal checklist. It becomes visible when Cal/OSHA shows up. See the signs your programs may have drifted →
An EHS gap assessment evaluates your California facility against the regulations that actually apply here: Cal/OSHA, CUPA-enforced hazardous materials programs, DTSC (the Department of Toxic Substances Control), the Air Districts, Regional Water Quality Control Boards, and local requirements that vary by jurisdiction. It identifies where your existing programs meet California standards and where they fall short. Read more about the process →
Beyond Cal/OSHA: The Full California Picture
Occupational safety is only one part of the regulatory landscape for California facilities. On the environmental side, your facility may be subject to requirements from CUPAs (which may be county environmental health departments, fire departments, or other local agencies depending on jurisdiction) for hazardous materials management, DTSC for hazardous waste, the State Water Board for stormwater, local Air Districts for emissions, and local sanitation districts for wastewater discharge. See the full environmental overview →
Each of these agencies has its own standards, inspection schedules, and enforcement mechanisms. A facility that’s compliant with federal EPA requirements may still have gaps under California’s state and local programs, the same pattern that applies to Cal/OSHA vs. federal OSHA.
Next Steps
If your California facility’s EHS programs were developed against federal standards, or if you’re not sure whether they account for California-specific requirements, the most efficient path is an outside review that checks your programs against what California actually requires.
