Cal/OSHA Compliance: California's Stricter State OSHA Plan
California operates its own OSHA State Plan — Cal/OSHA — enforced by the California Division of Occupational Safety and Health (Cal/OSHA). Cal/OSHA is consistently stricter than federal OSHA, covering all public and private sector employees in California. California employers must comply with Cal/OSHA standards rather than federal OSHA, and Cal/OSHA has issued unique requirements including the Injury and Illness Prevention Program (IIPP), Heat Illness Prevention Standard, and COVID-19 Prevention standard that have no direct federal equivalent.
Enforces California's OSHA State Plan; conducts inspections; issues citations and penalties; approves safety programs; higher penalty authority than federal OSHA
State Penalties: Cal/OSHA penalties: up to $25,000 per serious violation, up to $125,000 per willful or repeat violation. Repeat violations can be cited at 10× the serious violation rate. Cal/OSHA also issues citations faster than federal OSHA.
Federal Penalties: Federal OSHA: up to $16,550 per serious violation, up to $165,514 per willful/repeat violation (2025 adjusted amounts)
How Federal + California Law Overlap
Federal OSHA does not apply in California for workplaces covered by Cal/OSHA. California's State Plan covers all private sector and state/local government employees. Cal/OSHA must be at least as effective as federal OSHA but is typically stricter, with higher penalties and unique California-specific standards.

Does federal OSHA or Cal/OSHA apply to my California business?
Cal/OSHA applies to virtually all private sector and state/local government employers in California. Federal OSHA does not enforce in California for these workplaces. Cal/OSHA is administered by the California Division of Occupational Safety and Health and has its own standards that are often stricter than federal OSHA.
What is the Injury and Illness Prevention Program (IIPP)?
California's IIPP (Title 8 CCR §3203) requires every employer to have a written workplace safety program. It must include hazard identification, hazard correction, safety training, recordkeeping, and employee communication. Failure to have a written IIPP is one of the most commonly cited Cal/OSHA violations.
What are Cal/OSHA penalties vs. federal OSHA penalties?
Cal/OSHA penalties are significantly higher than federal OSHA. Cal/OSHA can assess up to $25,000 per serious violation and up to $125,000 per willful or repeat violation. Federal OSHA's comparable limits are approximately $16,550 per serious violation and $165,514 per willful/repeat violation. Cal/OSHA also has broader citation authority.
What is California's Heat Illness Prevention Standard?
Title 8 CCR §3395 requires California employers with outdoor workers to provide shade when temperatures reach 80°F, drinking water (1 quart per hour), rest periods, and training in heat illness recognition and prevention. California also adopted an indoor heat illness prevention standard in 2024 covering indoor workplaces where temperatures exceed 82°F.
How quickly must I report workplace injuries to Cal/OSHA?
California employers must report any serious injury, illness, or fatality to Cal/OSHA within 8 hours of learning of the incident. 'Serious injury' includes hospitalization for treatment (not just observation), loss of a body part, or disfigurement. Cal/OSHA's 8-hour window is faster than some reporting thresholds and requires immediate action.
