OSHA 1904.1 Small-Employer Exemption: 10-Employee Count Myths vs. Facts
For specialty trade subcontractors and small general contractors, understanding workplace safety rules is just as critical as managing labor costs and assembling precise estimates. A frequent point of confusion across small construction businesses involves routine safety recordkeeping and whether maintaining formal logs is legally required. Under federal safety standards, smaller operations may qualify for regulatory relief, but the exact rules governing eligibility are frequently misunderstood. Examining the regulatory text of 29 CFR 1904.1 clarifies common misconceptions about company size, establishment counts, and baseline reporting duties.
Myth 1: The Small-Employer Exemption Uses an Annual Average Headcount
Fact: Eligibility is determined strictly by your company's peak employment during the prior calendar year.
Contractors often assume they qualify for regulatory relief if their payroll averages ten or fewer workers over twelve months. In the construction industry, where staffing swings dramatically between bid awards and seasonal project phases, this misunderstanding can lead to compliance violations. Under 29 CFR 1904.1(b)(2), determining whether an employer qualifies for the partial exemption requires evaluating peak employment during the last calendar year. If an employer had more than ten employees at any single point during that year, the size exemption does not apply.
To qualify for the partial exemption under paragraph (a)(1), the business must have had 10 or fewer employees at all times throughout the entire preceding calendar year. Bringing on an eleventh worker even for a brief spike in project demand means the company had more than ten employees during that calendar year, triggering the general recording requirements unless the business falls under another specific exemption.
Myth 2: Multi-Branch Contractors Can Count Each Jobsite or Office Separately
Fact: The size exemption is calculated using the total headcount across the entire company.
Subcontractors operating multiple satellite yards, regional offices, or distinct project crews sometimes assume that each shop or jobsite functions as an independent unit for size determinations. Under this mistaken theory, a framing contractor with two regional branches employing six workers each might believe both locations remain exempt.
Paragraph 1904.1(b)(1) explicitly refutes this practice. The regulation states that the partial exemption for size is based on the total number of employees in the entire company rather than the size of an individual business establishment. When evaluating whether records must be maintained, an employer must aggregate all personnel across all company establishments. If that aggregate peak figure exceeded ten workers at any point during the prior calendar year, the employer does not qualify for the small-employer exemption.
Myth 3: Exempt Employers Never Have to Maintain OSHA Records Under Any Condition
Fact: Federal authorities may issue written instructions requiring exempt employers to keep injury logs.
Meeting the ten-employee threshold does not grant an unconditional or permanent waiver from recordkeeping duties. The standard provides a partial exemption, not an absolute barrier against recordkeeping mandates. Even if a small contractor maintains ten or fewer workers at all times, records must still be kept if directed by government agencies in writing.
Specifically, paragraph (a)(1) provides that employers with 10 or fewer workers do not need to maintain logs unless OSHA or the Bureau of Labor Statistics informs them in writing that they must keep records under § 1904.41 or § 1904.42. Trade contractors selected for statistical surveys or agency collection programs must maintain the appropriate records upon written notification.

Myth 4: Small Contractors Are Excused From Severe Incident Reporting
Fact: Every covered employer must report severe workplace incidents directly to OSHA.
Perhaps the most dangerous misconception is assuming that an exemption from routine log maintenance also excuses a small employer from notifying safety regulators following catastrophic jobsite events. Standard 29 CFR 1904.1(a)(1) clearly separates ongoing log maintenance from mandatory incident reporting.
All employers covered by the Occupational Safety and Health Act must comply with § 1904.39. Regardless of how small the business is, every covered employer must report to OSHA any work-related incident that results in:
- A work-related fatality;
- The in-patient hospitalization of one or more employees;
- An employee amputation; or
- An employee loss of an eye.
The small-employer size threshold provides relief solely from the administrative routine of maintaining standard logs, not from the statutory duty to report severe jobsite outcomes. For small specialty trades managing complex field risks, keeping these regulatory distinctions straight is just as vital as reviewing accurate crew overhead and Labor Burden: How to Calculate Your True Hourly Labor Cost.
Evaluating Your Exemption Status Under 29 CFR 1904.1
To determine where your company stands under the federal regulation, follow the specific criteria laid out in § 1904.1:
- Review company-wide payroll records for the entirety of the last calendar year.
- Identify your peak headcount at any point during that calendar year across all branches and establishments.
- If peak employment was 10 or fewer employees at all times, your firm qualifies for the partial exemption for size (unless notified in writing under § 1904.41 or § 1904.42).
- If peak employment reached more than ten employees at any point, your business must maintain injury and illness records unless classified under a partially exempt industry under § 1904.2.
- Regardless of headcount, ensure your team has procedures ready to report fatalities, in-patient hospitalizations, amputations, or the loss of an eye to OSHA under § 1904.39.
