North Dakota Private Investigator License: Requirements, Fees, and How to Open a Detective Agency

If you want to work as a private investigator in North Dakota, you need more than investigative skill and good judgment. You need to understand the state's licensing rules, application process, renewal deadlines, and agency registration requirements before you begin taking cases.

North Dakota regulates private investigative services through the Private Investigation and Security Board. The board oversees individual licensing, agency licensing, and related registrations for people who provide investigative services in the state. If you are planning to build a solo practice or launch a detective agency, the licensing rules should be part of your business plan from day one.

This guide walks through the current North Dakota private investigator license requirements, the steps to apply, the fees posted by the board, and the business formation steps that help you launch on a clean compliance foundation.

What the North Dakota license covers

North Dakota generally requires a license for individuals who provide private investigative services. In practical terms, that means you should not assume you can start accepting investigative work simply because you have experience in law enforcement, security, or surveillance.

According to the board's current licensing guidance, an individual must be licensed unless the person is registered as an employee of a licensed detective agency and is performing work within the scope of that employment. In other words, the license framework is designed to regulate both the investigator and the agency structure around that work.

If you intend to operate your own firm, you should think about two levels of compliance:

• Your personal qualification to act as a private investigator.
• Your business's authority to operate as a detective agency in North Dakota.

Types of licenses and registrations

The board's current forms and rules point to several related categories:

If you are starting a firm, the agency license matters just as much as the individual credential. The board also requires agency applicants to provide proof that the business is registered with the North Dakota Secretary of State.

That point is important for business owners: licensing is not only about investigative qualifications. It is also about forming and registering the company correctly.

Eligibility requirements for an individual license

North Dakota's eligibility rules are specific. Before applying, review the official Eligibility & Licensing Requirements for Private Investigators page and confirm that you meet the current standard.

Based on the board's published requirements, an individual must generally:

• Be at least 18 years old.
• Be a high school graduate or hold an equivalent diploma.
• Have a qualifying criminal record, which the board evaluates under its rules.
• Be free from a mental condition or defect that would interfere with professional service.
• Meet the board's moral character standard.
• Pass the required examination within the 12 months before applying.
• Complete 2,000 hours of private investigative services as a registered employee of a detective agency.

That last requirement is the one most applicants need to plan around. If you are early in your career, you may need to work under an existing agency long enough to build the required experience before you can hold an individual license.

What the application process looks like

North Dakota's application process is document-heavy. That is normal for regulated professions, but it means applicants should prepare before submitting anything.

The current application forms require the following for individual private investigator applicants:

• Pages 1, 2, 2a, 3, and 6 of the board application packet.
• Two legible fingerprint cards.
• A passport-sized photo submitted with the application.
• Supporting documents where applicable.

For detective agency applicants, the packet also requires:

• Pages 1, 2, 2a, 3, 4, and 6.
• Two legible fingerprint cards for the applicant.
• Fingerprint cards for managers and owners with at least 10% ownership.
• Proof of North Dakota Secretary of State registration.

A few practical tips help avoid delays:

• Use the board's current forms instead of old PDFs.
• Check that all fingerprint cards are readable and not folded or stapled.
• Match your business name consistently across state filings, the license application, and your formation documents.
• Keep copies of every form, fee payment, and supporting document you send.

You can find the current application packet on the board's Application Forms page.

Fees, renewals, and expiration dates

The board's current forms list the following fee structure for relevant licenses:

• Licensed Private Investigator: $225
• Licensed Detective Agency: $450
• One-time application fee for new applicants: $150

The board also posts a broader fee schedule on its forms page, so it is wise to verify the latest version before you submit payment. The board's current forms page was updated with new fees effective April 22, 2025.

Two deadlines matter for compliance:

• Licenses and registrations expire on September 30 each year.
• Late fees may apply to registrations that are not renewed on time.

Do not treat renewal as an afterthought. If you plan to keep serving clients, calendar the renewal window well before the fall deadline and confirm that your business and personal information are still accurate.

How to start a detective agency in North Dakota

If your goal is to open a detective agency instead of working solely as an individual investigator, treat the licensing process as one part of a broader business launch.

1. Choose the right business structure

Many owners choose an LLC or corporation because it creates a clear legal structure for contracts, taxes, and liability management. The right structure depends on how you plan to operate, how many owners you have, and how you want profits and management duties handled.

2. Register with the Secretary of State

North Dakota agency applicants must show proof of Secretary of State registration. That means you need to form and register the business before you can finish the agency license application.

3. Set up your internal compliance system

A detective agency should keep organized records for:

• Ownership and management changes.
• Employee registrations and license status.
• Renewal dates for the agency and each investigator.
• Fingerprint and identity documentation.
• Client contracts and scope-of-work agreements.

4. Open a business bank account and accounting workflow

Keep business and personal finances separate from the beginning. A clean accounting trail helps with tax reporting, fee payments, and any future audit or licensing questions.

5. Review insurance and contract practices

Investigative work often involves sensitive information, client expectations, and potential professional risk. Review insurance coverage and create solid client contracts before you start advertising.

Common mistakes to avoid

Many applicants run into the same avoidable problems:

• Applying before they have the required 2,000 hours.
• Submitting old or incomplete forms.
• Forgetting fingerprint cards or passport photos.
• Failing to register the business with the Secretary of State before applying for an agency license.
• Missing the September 30 expiration deadline.
• Assuming business formation and professional licensing are the same thing.

Those mistakes are expensive because they slow down approval and can interrupt your ability to serve clients.
