How to Start a PI Business in Minnesota (2026)

Last updated: February 25, 2026

As a licensed private investigator and small business owner myself, I know firsthand that Minnesota has one of the more demanding PI licensing processes in the country. The state requires 6,000 hours of documented investigative experience, a $10,000 surety bond, five character references, and a thorough FBI/BCA background check – all overseen by the Board of Private Detective and Protective Agent Services under the Department of Public Safety. The initial individual license costs $1,000 ($1,900 for a corporation/LLC), and there is no licensing exam – qualification is based entirely on documented experience and background. Licenses renew every 2 years. Armed personnel must complete additional annual weapons training. This guide covers every requirement from official Minnesota sources.

How to Start a Private Investigation Business in Minnesota (Step by Step)

Step 1: Accumulate 6,000 Hours of Investigative Experience

This is the biggest hurdle. Minnesota requires a minimum of 6,000 hours of qualifying investigative employment before you can apply. That’s approximately 3 years of full-time work. Qualifying experience includes:

Investigator with a licensed private detective or investigative agency
Investigator with a U.S. government investigative service
Investigator with a city police department or sheriff’s office
Other board-approved equivalent investigative occupations

Critical: Employer verification statements must be submitted under oath. Unlicensed investigative activity does NOT count, and anyone found conducting unlicensed PI work is barred from applying for one year.

Step 2: Form Your Business Entity

Register an LLC with the Minnesota Secretary of State ($155 online, free annual renewal). For a corporation/LLC license, at least one member or officer must meet all individual licensing qualifications and be designated as the Qualified Representative. Non-resident applicants establishing a Minnesota office must designate a qualified Minnesota Manager. Get a federal EIN from the IRS.

Step 3: Secure Your Surety Bond and Insurance

Surety bond: A $10,000 surety bond is required, executed by a company authorized to do business in Minnesota. The bond covers damages from law violations or willful/malicious wrongs in the course of business. Typical premium: $100-$500/year depending on credit.

Proof of financial responsibility (one of the following):

Certificate of insurance covering general liability, completed operations, and personal injury (including false arrest, defamation, wrongful entry/eviction coverage)
Net worth statement: $10,000 minimum (no employees) up to $100,000 (51+ employees)
Irrevocable letter of credit from an approved financial institution

Step 4: Submit Your License Application

Apply to the Board of Private Detective and Protective Agent Services:

License Type	Individual Fee	Corporation/LLC Fee
Private Detective (initial)	$1,000	$1,900

Application requirements:

Completed application form
Recent photograph and fingerprints
Five character references from persons who have known you for at least 5 years
Documented 6,000 hours of investigative experience (employer verification under oath)
$10,000 surety bond
Proof of financial responsibility
Payment by check or money order only (payable to “MN Board of Private Detective & Protective Agent Services”)

Step 5: Pass the Background Check and Public Notice Period

The Board conducts a thorough review including:

Fingerprint submission to BCA (state criminal history) and FBI (federal criminal history)
20-day public notice period during which the Board investigates qualifications
Review of character, honesty, and integrity

Disqualifying convictions: felony, sexual conduct crimes, assault, theft, burglary, robbery, weapons violations, narcotics offenses, or equivalents in other jurisdictions. A pardon may clear a disqualification.

No exam required. Minnesota does not administer a licensing exam for private detectives.

Step 6: Ongoing Requirements

Continuing education: 6 hours per year (12 hours per 2-year renewal cycle) of board-certified training.

Armed personnel additional requirements:

6 additional hours of weapons training annually
Annual firing range certification
First aid certification
CPR certification
Training on justified force (MN Statutes 609.06 and 609.065)
Must also hold a Minnesota Permit to Carry (MN Statute 624.714) – apply through county sheriff, valid 5 years

License renewal (every 2 years):

Number of Employees	Renewal Fee
1 (sole operator)	$540
2-10	$710
11-25	$880
26-50	$1,050
51+	$1,220
