N.D. Cent. Code § 43-30-02.2 (2025)
A proprietary employer is a person who employs an individual to provide security for that person's own property or protection. A proprietary employer is not required to be licensed as a private security service if the employer does not offer or provide security services to others. Proprietary security employees may be voluntarily registered as security officers under section 43-30-06. In order to be registered as a proprietary security officer, an employee must meet all of the requirements to be registered as a security officer except for:
1. Employment by a licensed private security service; and
2. Supervision by an individual who is licensed to provide security services.
