To get a private investigator license in Minnesota, you must be at least 18, pass a background check, document 6,000 hours of qualifying investigative experience, and apply through the Minnesota Board of Private Detective and Protective Agent Services. There is no written exam. License fees start at $1,000 for individuals.
Minnesota’s private investigators work across the full range of investigations — corporate background checks, insurance fraud, workers’ compensation surveillance, missing persons, infidelity cases, and litigation support for civil and criminal attorneys. The state licenses all of it through the Minnesota Board of Private Detective and Protective Agent Services, and the experience requirement for entry is substantial: 6,000 documented hours of investigative work before you can apply.
From Minneapolis and Saint Paul to Duluth and Rochester, Minnesota PIs serve attorneys building civil and criminal cases, insurance carriers investigating fraud, corporations running employee background checks, and private clients dealing with everything from custody disputes to missing family members. BLS data counts 940 private investigators employed in the state as of May 2024 — and the outlook is growing.
Step 1. Meet Minimum Requirements for Private Detective Licensure in Minnesota
To become a private investigator in Minnesota, you must first meet the Board’s minimum eligibility requirements before you can even request an application packet:
- You must be at least 18 years old.
- Certain felony convictions may disqualify applicants. The Board reviews criminal history as part of the background check.
- You must be able to supply a $10,000 surety bond at the time of your application.
- You must be able to supply proof of Financial Responsibility at the time of your application.
- You must be of good character, honesty, and integrity. References will be required.
Minnesota does not require a written exam for licensure. What it does require — and what distinguishes this state from many others — is substantial documented work experience. That experience requirement is covered in Step 3.
Step 2. Complete a Comprehensive Education Program in Minnesota
Minnesota doesn’t require a degree to get licensed, but education makes a real difference in how quickly you qualify. Many employers in law enforcement and investigative agencies now look for candidates with formal training in criminal justice programs, forensics, law, or a related field. A degree can open doors to the kinds of jobs that generate the 6,000 hours of experience you’ll need for licensure.
The Board does not certify or approve specific training programs, so there’s no required course of study before you apply. The value of education here is practical: it positions you for the investigative roles that count toward your experience hours, and it can give you a competitive edge when applying to agencies or firms.
Step 3. Show Proof of Documented Professional Hours
The experience requirement is the most significant hurdle on the path to licensure in Minnesota. You must document a minimum of 6,000 hours of investigative employment — approximately three years of full-time work — in one or more of the following categories:
- Investigator with a licensed private detective or investigative agency
- Investigator with a U.S. government investigative service
- Investigator for a city police department or sheriff’s office
- An investigative occupation that the Board determines is equivalent in scope, responsibility, and training to one of the above
That fourth category matters. If your background includes investigative work that doesn’t fit neatly into the first three — federal regulatory enforcement, military intelligence, or a corporate fraud investigation role, for example — contact the Board to determine whether it qualifies before you count it out.
Out-of-state agencies that want to operate in Minnesota must designate a Minnesota Manager: an individual who meets the same 6,000-hour experience standard and will serve as the day-to-day supervisor of licensed activity within the state.
Step 4. Request a Minnesota Application Package
Once you’ve met the experience requirements, you can request an application package from the Board. Submit a non-refundable fee of $25 (payable to the Board of Private Detective and Protective Agent Services) along with a written request specifying that you want a private detective application and the license level you’re applying for. Mail it to:
State of Minnesota
Board of Private Detective and Protective Agent Services
1430 Maryland Avenue East
St. Paul, Minnesota, 55106
You may apply as a Sole Proprietor (individual), a Partnership/LLP, or a Corporation/Limited Liability Company (LLC). If you’re applying as a sole proprietor, you’ll serve as the day-to-day manager and supervisor of all licensed activity. Partnerships and corporations must designate a qualified representative who meets the experience requirements and fills that supervisory role. If you’re considering the agency route, see our guide on establishing an independent PI agency.
Step 5. Apply for Licensure in Minnesota as a Private Investigator
Once you receive your application packet, complete it and return it to the Board along with the applicable license fee and all required supporting documents.
License Fees by Entity Type
| License Type | Initial Fee |
|---|---|
| Individual (Sole Proprietor) | $1,000 |
| Partnership / LLP | $1,700 |
| Corporation / LLC | $1,900 |
In addition to the fee, your application must include:
- A completed informed consent criminal history form
- A recent photograph
- A full set of fingerprints
- Five references from people not related to you who have known you for at least five years
- Documentation of work experience (if applying as a qualified representative)
Step 6. Getting to Work in Minnesota
New employees working under a licensed agency must complete pre-assignment training within the first 21 days on the job. Minnesota requires at least 12 hours of initial training, and it’s the employer’s responsibility to make sure that requirement is met. A list of approved training providers and course application documents is available on the Board of Private Detective and Protective Agent Services website.
If you’ll be carrying any weapon — firearm, baton, or other device — you must also complete armed training, which adds 6 hours and includes first aid and CPR certification.
Licensed Minnesota PIs work across a wide range of case types. On any given week, that might include surveillance on a workers’ compensation claimant, a background investigation for a corporate client, locating a missing person for an attorney, or documenting infidelity evidence for a contested divorce. Insurance fraud, elder abuse investigations, and asset searches round out the day-to-day for many investigators in the Twin Cities market.
Step 7. Maintain your Minnesota License
Minnesota PI licenses renew on a two-year cycle. To renew, you must complete at least 6 hours of continuing training during each renewal period. If you complete more than 6 hours in any given period, the excess can roll over to the next renewal cycle — except for armed training hours, which don’t carry over.
License Renewal Fees by Employee Count
| Employee Count | Renewal Fee |
|---|---|

| 1 to 10 employees | $710 |
| 11 to 25 employees | $880 |
| 26 to 50 employees | $1,050 |
| 51 or more employees | $1,220 |

Can I get a Minnesota PI license without prior law enforcement experience?
Yes. Minnesota accepts experience from licensed private detective agencies and U.S. government investigative services, not just police or sheriff’s offices.

This applies whether you’re expanding an existing agency or opening a new branch.
