Labor Code 6401.9

Does SB 553 Apply to Your Cleaning Contractor?

California's workplace violence law reaches the janitorial company as an employer, and it expects that company and your building to coordinate. Here is what that means for night crews.

The short answer

SB 553 applies to most cleaning contractors. It added Labor Code section 6401.9, which since July 1, 2024 has required most California employers to maintain a written workplace violence prevention plan, keep a violent incident log, train employees and keep records. The contractor's plan covers its own cleaners at your site, and it must describe how the contractor coordinates with other employers there, such as the property owner or tenants, so each understands its role.

What does Labor Code section 6401.9 require?

The law sets out a working program, not a policy statement. The plan may be a stand-alone document or a separate section of the employer's IIPP, and it has to be in effect and available to employees, not just on file. Training is required when the plan is first established and annually after that.

Who is exempt, and why most cleaning contractors are not

The exemptions are narrow. The law does not apply to health care facilities and operations covered by Cal/OSHA's separate health care workplace violence standard, Title 8 section 3342, to employees teleworking from a place of their choosing outside the employer's control, to law enforcement agencies, or to facilities run by the state corrections department. It also excludes places of employment with fewer than 10 employees present at any time that are not accessible to the public, if the employer complies with section 3203.

A janitorial company rarely fits. Its employees work across many client buildings, many of them open to the public, and the small-workplace exemption is judged place by place. Even a contractor whose crews clean inside hospitals usually needs a plan for its other sites.

How workplace violence reaches night cleaning crews

The law sorts workplace violence into four types, and cleaners can meet all of them. Evening and weekend shifts, working alone, unlocked entrances and isolated spaces such as parking structures and loading docks raise the risk.

  • Type 1: violence by someone with no legitimate business at the site, such as a trespasser met during an evening shift
  • Type 2: violence by customers, clients, patients or visitors, such as a tenant or member of the public in a lobby
  • Type 3: violence by a current or former employee, supervisor or manager
  • Type 4: violence by someone who has a personal relationship with the employee and follows them to work

How should the building and the cleaning contractor coordinate?

The contractor's plan must describe how it coordinates with other employers on the site, and the host has good reasons to cooperate: its own plan covers its own staff, and one incident can involve both workforces. Coordination is mostly about sharing information in both directions.

Agree on how the night crew reaches building security, how doors are locked and checked during the shift, whether cleaners may let anyone in, where they go if a threat appears and how incidents are reported to each employer. Each employer logs incidents affecting its own employees, so a lobby confrontation involving a cleaner and a building employee may belong in two logs.

What to ask your cleaning contractor about its plan

These questions also test whether the plan reaches the people working in your building or stays in an office binder.

  • Who is responsible for the plan, and how can your site contact reach them?
  • How does the plan cover cleaners working alone or late at night in your building?
  • How does a cleaner report a threat during a shift, and who do they call first?
  • How will the contractor tell you about incidents at your property?
  • Has the crew assigned to your site completed training on the plan, and when is it repeated?
  • How are your building's security and emergency procedures built into the contractor's plan?

How EBS works in access-controlled buildings

EBS has cleaning experience in high-security and access-controlled facilities, including government and secure-facility operations, where security protocols, confidentiality and accountability are part of the job. Its people are background-checked and uniformed, so they are identifiable on site, and field supervisors keep in contact with the client. Escalation support and a 24/7 priority line give night crews a route to help. Door and alarm procedures, security contacts and incident reporting can be written into the site scope at the walkthrough.

Do we have to include contract cleaners in our own workplace violence plan?

Your plan covers your own employees, but it must also describe how you coordinate with other employers on the site. In practice that means giving the cleaning contractor your security procedures and reporting routes, and agreeing how incidents involving both workforces are shared.

Is SB 553 the same as the health care workplace violence rule?

No. Health care facilities covered by Title 8 section 3342 follow that separate standard and are carved out of Labor Code section 6401.9. A cleaning company working in both settings needs to know which rules apply at each site.

Has Cal/OSHA adopted a general industry workplace violence regulation?

The law directs the Standards Board to adopt a general industry standard by December 31, 2026, and Cal/OSHA has been developing one. Until a standard takes effect, the statute's requirements apply, so check Cal/OSHA's website for current status.

Can the workplace violence plan be part of the IIPP?

Yes. The plan may be a separate section of the Injury and Illness Prevention Program or a stand-alone document. Either way it must be written, easy for employees to access and actually carried out.

How long must the violent incident log be kept?

At least five years. Records of hazard identification, evaluation and correction, and of incident investigations, are also kept for at least five years, while training records are kept for at least one year.
