California turns workplace safety violations into criminal offenses

Block a Cal/OSHA inspector and you could end up in handcuffs. 

California Governor Gavin Newsom signed AB 2321 on September 30, 2026, turning workplace safety violations into a faster track to criminal prosecution. The bill, authored by Assembly Member Liz Ortega, rewrites six sections of the California Labor Code and takes effect January 1, 2027. 

Here is what changed. Previously, a willful safety violation only triggered criminal liability if it caused death or permanent impairment. That bar has dropped. Under the new law, any willful violation causing "serious injury or illness or serious exposure" is now a criminal offense. 

The fines match the intent. A first offense can mean up to a year in county jail, a fine up to $100,000, or both. Corporate and LLC defendants face up to $1.5 million. Repeat offenders within seven years face steeper penalties - up to $2.5 million for companies on a second conviction, with a $500,000 floor. A subsequent conviction under the same provision pushes the corporate ceiling to $3.5 million. 

There is also a brand-new misdemeanor for obstruction. Anyone who "willfully resists, prevents, impedes, or interferes" with a Cal/OSHA inspector faces up to six months in jail, a $5,000 fine, or both. The same goes for violating a court order tied to an inspection. 

The investigation pipeline got a complete overhaul. Cal/OSHA's Bureau of Investigations must now look into any workplace accident where a willful-violation citation is issued alongside a serious injury, illness, or exposure. The bureau must also create written policies for deciding when to investigate or refer cases for prosecution - and document why when it passes. 

Prosecutors, meanwhile, will hear about serious incidents almost immediately. Responding fire or police agencies must now notify the local district attorney's office directly when a serious workplace accident occurs. Cal/OSHA must do the same - notifying both the bureau and the DA, regardless of how the division first learned about the incident. 

One more change worth flagging: trade-secret information collected during Cal/OSHA inspections can now be shared with law enforcement during investigations. That wall between regulatory and criminal enforcement just got a lot thinner. 

For HR teams across California, the message is practical. The distance between a safety citation and a prosecutor's desk has shrunk, and the people who decide whether to charge will know about serious incidents from day one. Treating a Cal/OSHA inspection as routine paperwork is a riskier bet than it used to be. 

AB 2321 takes effect January 1, 2027, and applies to all California employers.
