The SB 553 exemption list is short and each line has gates. Why most California employers who think they are exempt are not, and how to check where you sit.
The most common SB 553 question is also the most dangerous one to answer casually: does this law apply to us? Labor Code 6401.9 starts from the broadest possible position, it applies to all employers, employees, places of employment, and employer-provided housing in California, and then carves out a short list of exemptions. Most employers who think they are exempt are reading the list more generously than it was written.
The statute exempts five categories:
Healthcare facilities and operations already covered by Section 3342 of Title 8, California's healthcare-specific workplace violence standard, and employers complying with that standard. Corrections facilities compliant with their own industry rules. Certain law enforcement agencies confirmed compliant through the POST program. Employees teleworking from a location of their own choosing that the employer does not control. And places of employment with fewer than 10 employees working at any given time, that are not accessible to the public, and that are compliant with the general injury and illness prevention program rules.
Everyone else needs a written workplace violence prevention plan, and needed one by July 1, 2024.
The under-10 exemption is the one small businesses reach for, and it has three separate gates. Fewer than 10 employees at the place at any given time. Not accessible to the public. Compliant with the IIPP requirements. Miss any one and you need a plan.
The public-access gate is the killer. A six-person accounting office in a secured building with no walk-in traffic plausibly qualifies. A four-person retail shop, cafe, salon, or clinic reception does not, because the public can walk in. Headcount also counts whoever is working at the time, including the owner behind the register, and the exemption looks at each place of employment, not the company as a whole.
The healthcare carve-out is not a blanket exemption for anything medical. It covers facilities and operations under the healthcare violence standard, and employers in compliance with it. A hospital clearly sits there. A small outpatient clinic or dental office should not assume; the question is whether its operation is covered by, and compliant with, Section 3342. If the honest answer is "we have never looked at 3342," then the safer reading is that SB 553's general requirement applies, and the written plan, log, and training obligations come with it.
An employee working from their own kitchen table, at a location they chose and the employer does not control, is exempt. That does not exempt the office they visit twice a week, and it does not exempt the employer from covering the rest of the workforce. The exemption follows the employee and the place, not the company.
The statute gives Cal/OSHA the power to order even an exempt employer to comply, by special order. Exemption is a default, not a shield. And none of the exemptions touch the employer's general duty to provide a safe workplace; they only lift the specific written-plan, log, and training machinery.
If you are a California employer with employees who interact with the public, work in shared or accessible spaces, or number ten or more on site, the answer is almost certainly yes, you need a plan. The exemptions were written for genuinely closed, small, or separately regulated workplaces. When in doubt, assume you are covered: the cost of building a plan is modest, and the cost of being wrong is a citation plus whatever the incident itself costs.
