OSHA does apply to small businesses. The Occupational Safety and Health Act covers nearly every private-sector employer in the United States from the moment the first employee is hired, with no minimum revenue, headcount, or business-structure threshold to clear.1U.S. Department of Labor. Safety and Health Standards: Occupational Safety and Health What changes with size is the paperwork and the odds of a routine inspection, not the underlying duty to keep the workplace safe.
When Coverage Starts
Coverage begins with your first employee, whether full-time, part-time, or seasonal. Your legal form — LLC, corporation, sole proprietorship — does not matter, and neither does revenue.1U.S. Department of Labor. Safety and Health Standards: Occupational Safety and Health
A short list of situations sits outside OSHA’s reach:
- Self-employed people with no employees.2Occupational Safety and Health Administration. 29 CFR 1904.31 – Covered Employees
- Farms where the only workers are the owner’s spouse, parents, children, or siblings.1U.S. Department of Labor. Safety and Health Standards: Occupational Safety and Health
- Domestic workers privately hired in someone’s home for cleaning, cooking, or childcare.3Occupational Safety and Health Administration. 29 CFR 1975.6 – Policy as to Domestic Household Employment Activities in Private Residences
- Workplaces where another federal agency regulates the hazard, such as mining (MSHA), nuclear facilities (NRC), and parts of transportation (FAA, FMCSA).4Occupational Safety and Health Administration. Field Operations Manual – Chapter 17
Everyone else with at least one employee is covered.
What Every Small Employer Has to Do
Certain obligations follow every covered employer, and none of them turn on headcount.
The General Duty Clause
Section 5(a)(1) of the OSH Act requires you to provide a workplace free from recognized hazards likely to cause death or serious physical harm.5Occupational Safety and Health Administration. OSH Act of 1970 – Section 5 Duties If an employee is exposed to a serious danger — an unguarded machine, toxic fumes, a fall hazard — OSHA can cite you under this clause even when no specific standard fits the exact situation.1U.S. Department of Labor. Safety and Health Standards: Occupational Safety and Health
Hazard Communication
If your people work with or near hazardous chemicals, including everyday products like cleaning solvents or adhesives, you need a written hazard communication program, a Safety Data Sheet accessible on every shift for each hazardous chemical, proper labeling on every container, and training for the workers who might come into contact with those chemicals.6Occupational Safety and Health Administration. 29 CFR 1910.1200 – Hazard Communication
Emergency Action Plans
Employers required to have an emergency action plan must put it in writing if they have more than ten employees. With ten or fewer, the plan can be communicated orally.7Occupational Safety and Health Administration. 29 CFR 1910.38 – Emergency Action Plans Either way, workers need to know evacuation routes, alarms, and who to contact.
First Aid
If your workplace is not near a hospital, clinic, or infirmary, at least one person on site must be trained in first aid, and you need adequate supplies.8eCFR. 29 CFR 1910.151 – Medical Services and First Aid
The OSHA Poster
The “Job Safety and Health: It’s the Law” poster has to be displayed somewhere employees will see it. Not posting it is itself a citable violation, and the poster is free from OSHA in several languages.9Occupational Safety and Health Administration. OSHA Job Safety and Health Workplace Poster
Severe Incident Reporting
Regardless of size, you must report a work-related fatality within eight hours, and an inpatient hospitalization, amputation, or loss of an eye within twenty-four hours.10eCFR. 29 CFR 1904.39 – Reporting Fatalities, Hospitalizations, Amputations, and Losses of an Eye
Whistleblower Protection
Under Section 11(c) of the OSH Act, it is illegal to fire, demote, cut hours, withhold benefits, or otherwise retaliate against an employee for filing an OSHA complaint, taking part in an inspection, or reporting a work-related injury. If OSHA finds retaliation and cannot reach a voluntary settlement, the Department of Labor can sue in federal court for reinstatement, back pay with interest, and damages.
Where Being Small Actually Helps
Recordkeeping — Ten or Fewer Employees
A business that had ten or fewer employees at all times during the previous calendar year does not have to keep the standard injury and illness logs, meaning OSHA Forms 300, 300A, and 301. The count is based on peak employment during the prior calendar year and includes part-time and seasonal workers. Hire an eleventh person for even a week and you lose the exemption for the following year.11Occupational Safety and Health Administration. 29 CFR 1904.1 – Partial Exemption for Employers With 10 or Fewer Employees The exemption covers the logs only; the severe-incident reporting rule above still applies.
Low-Hazard Industries
Separately, certain industries are partially exempt from the same recordkeeping regardless of headcount. OSHA identifies these using NAICS codes, and the list includes banking, insurance, real estate brokerage, legal services, accounting, computer systems design, advertising, and management consulting, among others.12Occupational Safety and Health Administration. 1904 Subpart B Appendix A – Partially Exempt Industries Falling under a listed NAICS code means you skip Forms 300, 300A, and 301 unless OSHA or the Bureau of Labor Statistics asks in writing. Fatality and severe injury reports still apply, and OSHA can still inspect if someone files a complaint.13Worker.gov. Filing a Complaint With the Occupational Safety and Health Administration (OSHA)
No Programmed Inspections for Very Small Employers in Low-Hazard Industries
A federal appropriations rider blocks OSHA from spending money on routine inspections of employers that currently have ten or fewer employees, have not exceeded ten at any point in the previous twelve months, and operate in an industry whose Days Away, Restricted, or Transferred (DART) rate falls below the national average.14Occupational Safety and Health Administration. OSHA Enforcement Exemptions and Limitations Under the Appropriations Act The most recent national DART rate used for this determination is 1.4.15Occupational Safety and Health Administration. 2026 Low-Hazard Industries Table Qualifying NAICS codes shift year to year as BLS data updates. The exemption blocks scheduled inspections only. OSHA can still show up for a complaint, a severe incident, or another exception under the rider.
Small Farms
Farms that hire non-family workers can still qualify for an enforcement exemption. Since 1976, Congress has barred OSHA from spending money to inspect farms with ten or fewer non-family employees that have not operated a temporary labor camp within the preceding twelve months.16Occupational Safety and Health Administration. Policy Clarification on OSHA’s Enforcement Authority at Small Farms Family members do not count toward the ten.17Occupational Safety and Health Administration. Agricultural Operations: OSHA Enforcement Limitations and Standards Operate a temporary labor camp or cross the ten-worker line and full enforcement resumes.
Your State May Add More
Twenty-two state and territory plans cover private-sector and government workers, and seven more cover only state and local government employees.18Occupational Safety and Health Administration. State Plans Every state plan must be at least as effective as the federal program, and many go further.19eCFR. 29 CFR Part 1902 Subpart A – General Some require a written injury and illness prevention program from employers of all sizes; others tie the requirement to employee count or industry. A few impose higher minimum penalties or inspect more often. Check with your state’s occupational safety agency before assuming the federal picture is complete.
Penalties If You Get It Wrong
Penalty maximums adjust each year for inflation. As of January 15, 2025:
- Serious violation: up to $16,550 per violation.20Occupational Safety and Health Administration. OSHA Penalties
- Other-than-serious violation: up to $16,550 per violation.20Occupational Safety and Health Administration. OSHA Penalties
- Willful or repeated violation: up to $165,514 per violation.20Occupational Safety and Health Administration. OSHA Penalties
- Failure to abate: up to $16,550 per day past the correction deadline.20Occupational Safety and Health Administration. OSHA Penalties
- Posting requirement violation: up to $16,550 per violation.20Occupational Safety and Health Administration. OSHA Penalties
A willful violation that causes an employee’s death can also bring criminal liability, including up to six months of imprisonment under the OSH Act.21Occupational Safety and Health Administration. OSH Act of 1970 – Section 17 Penalties
Free Help Built for Small Employers
OSHA’s On-Site Consultation Program offers free, confidential workplace safety assessments to small and medium-sized businesses. It is separate from enforcement, so participating will not trigger an inspection or citations. The consultant identifies hazards, suggests fixes, and agrees with you on reasonable timelines for correcting anything serious.22Occupational Safety and Health Administration. OSHA On-Site Consultation Program
Businesses that go further — correcting all identified hazards, keeping injury rates below the national average, and running an effective safety program — can apply for the Safety and Health Achievement Recognition Program (SHARP). Eligible businesses must have 250 or fewer employees on site and fewer than 500 company-wide. SHARP participants receive an exemption from OSHA’s programmed inspections for up to two years, renewable for up to three, along with formal recognition from the agency.23Occupational Safety and Health Administration.
