California Active Shooter Rules for Employers and Schools

California active shooter rules for employers and schools come down to two core mandates: nearly every employer in the state must maintain a written Workplace Violence Prevention Plan under SB 553, and every K-12 school must build tactical response procedures for armed intruders into its comprehensive school safety plan. Both carry training requirements, documentation obligations, and real financial consequences for falling short.

Employer Obligations Under SB 553

SB 553 took effect July 1, 2024, adding Labor Code Section 6401.9. It requires nearly every California employer to establish, implement, and maintain a written Workplace Violence Prevention Plan that is available to employees at all times and addresses hazards specific to each work area.¹

The statute defines workplace violence broadly. It covers any act or threat of violence occurring at a place of employment, grouped into four types: violence by someone with no connection to the business, violence by customers or clients, violence by current or former employees, and violence by someone with a personal relationship with an employee. An active shooter event falls squarely within this framework.¹

What the Written Plan Must Contain

At minimum, the plan must identify the people responsible for implementation by name or job title, describe procedures for employee involvement in developing the plan, and lay out methods for coordinating with other employers at a shared worksite. It must also include procedures for responding to emergencies, reporting incidents without retaliation, and investigating incidents afterward.²

Beyond the plan document, employers must keep a violent incident log recording the details of every workplace violence event. Logs must be retained for at least five years and provided to employees, their representatives, or Cal/OSHA within 15 calendar days of a request, at no cost.²

Training Required for Every Employee

A plan sitting in a drawer satisfies nothing. SB 553 requires initial training for all employees and annual refresher training afterward. Additional focused training is required whenever new hazards are identified or the plan changes.³

Training must cover how employees can obtain the plan, how to report incidents without fear of retaliation, job-specific hazards and corrective measures, the purpose of the violent incident log, and an interactive discussion with someone knowledgeable about the plan. Handing out a pamphlet does not satisfy the interactive requirement. Employees must have the chance to ask questions and get real answers.³

Who Is Exempt

Not every employer falls under SB 553. The law exempts healthcare facilities already covered by existing Cal/OSHA regulations, Department of Corrections and Rehabilitation facilities, and law enforcement agencies that comply with POST standards. Employees who telework from a location of their own choosing not under the employer’s control are also excluded. Workplaces with fewer than ten employees that are not open to the public and already comply with California’s Injury and Illness Prevention Program requirements are exempt as well.¹

Even inside an exempt category, Cal/OSHA can require compliance by special order when a workplace presents elevated risks.

What Schools Must Include in Their Safety Plans

Every school district and county office of education must develop a comprehensive school safety plan for each campus serving kindergarten through grade 12. The schoolsite council writes the plan in consultation with local law enforcement, fire departments, and other first responders, and the finished plan and any updates must be shared with those agencies.⁴

Education Code Section 32282 requires the plan to include procedures for tactical responses to criminal incidents, specifically covering situations involving individuals with guns on campus. These procedures must be tailored to the school’s specific needs and community context.⁵ Active shooter planning is not optional supplemental content for California schools. It is a required component of the safety plan itself.

Small districts with fewer than 2,501 units of average daily attendance can adopt a single districtwide plan rather than separate plans for each school. Districts may also choose, in consultation with law enforcement, to have administrators develop the tactical response portions instead of the schoolsite council, and those portions can be kept confidential.⁴

Rules for Active Shooter Drills in Schools

AB 1858 amended Education Code Section 32282 to add detailed restrictions on how schools conduct active shooter drills. The law does not require schools to run active shooter drills. Tactical response procedures must appear in the safety plan either way. When a school chooses to drill, however, every one of these rules applies:⁶

No high-intensity simulations. Drills cannot include theatrical makeup simulating blood or wounds, anyone acting as a shooter, anyone acting as a victim, or instructions for students to physically attack or swarm an assailant.
No real weapons, gunfire blanks, or explosions.
Drill content and terminology must be age-appropriate and developmentally appropriate, created with the involvement of school-based mental health professionals.
Parents, teachers, administrators, and school personnel must receive advance notice, including the expected duration.
Parents can opt their children out entirely.
Students and staff must hear a clear announcement immediately before the drill begins and another immediately after it concludes.
After the drill, parents must receive a notice along with contact information for community resources such as mental health counseling and gun violence reduction organizations.

How the Response Framework Fits In

The response protocol most California plans train to is the Run-Hide-Fight framework from CISA and the Department of Homeland Security. Run, if you can identify where the threat is coming from. Hide in a room you can lock and barricade, out of the shooter’s line of sight, with your phone silenced, when escape is not possible. Fight only as an absolute last resort, committing to decisive action to incapacitate the shooter with whatever is at hand.⁷

Fight is a survival option, not a preferred response. California’s drill rules reflect that hierarchy by expressly prohibiting schools from training students to swarm or physically attack a shooter during drills, even though the Fight component exists in the broader framework.⁶

Plans should also account for people with disabilities and access or functional needs. The California Governor’s Office of Emergency Services recommends buddy systems and involving people with disabilities in planning and simulation exercises; alerts should reach everyone through multiple channels, and no one should be left to evacuate without assistance.⁸

Penalties for Non-Compliance

Employer Fines and Criminal Exposure

Cal/OSHA enforces SB 553. As of 2025, serious violations carry a maximum penalty of $25,000 per violation. Willful or repeat violations can reach $162,851, with a minimum of $11,632 for willful offenses. These amounts adjust annually for inflation. An employer with no written plan, no training records, or no violent incident log can be cited separately on each deficiency.

Criminal penalties apply to the worst failures. Under Labor Code Section 6425, an employer who willfully violates a safety standard and whose violation causes an employee’s death or permanent impairment faces up to one year in county jail, a fine up to $100,000, or both. Corporate fines can reach $1,500,000. A repeat conviction within seven years escalates to state prison time and corporate fines up to $2,500,000.⁹

Employers should also keep the general duty clause in mind. California and federal OSHA both require a workplace free from recognized hazards likely to cause death or serious physical harm.¹⁰ Active shooters have been recognized as a workplace hazard. SB 553 made the specific obligations explicit; the underlying duty predates it.

School Liability

The penalty structure for schools is less direct. California law requires comprehensive school safety plans, but the statutes do not specify a mechanism for stripping state funding from schools that fail to comply. What exists is the state’s general authority to enforce mandated programs and the practical reality that a school without an adequate safety plan faces severe civil liability exposure if an incident occurs. AB 1858 requires the state to reimburse schools for costs tied to its new drill requirements, which signals that the legislature treats these as funded mandates rather than conditions on existing funding.⁶

Gun Violence Restraining Orders as a Prevention Tool

Preparedness is not only about responding when something happens. California’s Gun Violence Restraining Order is a civil court order that temporarily suspends a person’s access to firearms, ammunition, magazines, and body armor when evidence shows they pose a significant danger of causing injury.

Law enforcement officers, family members, co-workers, employers, and certain other eligible petitioners can file for a GVRO in Superior Court. The legal standard varies by urgency: emergency orders require reasonable cause, temporary orders require substantial likelihood, and longer-term orders after a hearing require clear and convincing evidence. A GVRO does not name protected parties or require the subject to stay away from specific people or locations. It addresses dangerous firearm access only.¹¹

For employers and schools building threat assessment procedures into their plans, the GVRO is an actionable option when someone shows warning signs. If a co-worker makes credible threats or a student’s behavior raises alarms, knowing that this legal mechanism exists, and knowing how to involve law enforcement in petitioning for one, can be the difference between an intervention and an incident.

How California Defines an Active Shooter

Penal Code Section 13519.12(e) defines an active shooter incident as one in which a person is actively engaged in killing or attempting to kill people. The statute places the definition within the broader category of terrorism incidents, which closely mirrors the federal description from the Department of Homeland Security.¹² 13 The classification matters because it ties the response to specific law enforcement training curricula and multi-agency coordination requirements, and because it leaves no room for an employer or school to argue the category is undefined under state law.
