Private investigator licensing in Minnesota

Yes. Private investigators need a licence in Minnesota. The Board of Private Detective and Protective Agent Services licenses private detective businesses run by an individual or a corporation, which names a qualified representative; since 2026 partnerships can no longer hold a licence. The individual or qualified representative must document 6,000 hours of investigative employment with a licensed agency, a US government investigative service, a police or sheriff's department, or an equivalent occupation. Every signer must be 18, supply fingerprints and five references, and the business files a $10,000 surety bond plus proof of financial responsibility before a board review and interview.

1. Check the individual or qualified representative has 6,000 hours of qualifying investigative employment and that each signer is 18 or over with no disqualifying convictions (the optional Preliminary Criminal History Background Application tests eligibility first) 2. Download the private detective application packet that matches your business type from the board's licensing page 3. Gather a $10,000 surety bond, proof of financial responsibility, five references, a photograph, fingerprints and BCA/FBI consent for each signer, and documented work experience 4. Post the application with the licence fee, paid by check or money order to the board 5. The board posts notice of the application for 20 days, investigates, and reviews it at a board meeting that includes an in-person interview 6. Within 21 days of approval, complete the 12-hour board-certified preassignment private detective course

No temporary or per-case permit exists: anyone doing private detective work in Minnesota needs a board licence, and an out-of-state firm that opens a Minnesota office must appoint a Minnesota manager who meets the licensing requirements.

None: Minnesota has no reciprocity agreements or licence-recognition provision for investigators licensed in other states.

Minnesota is a one-party consent state: you can generally record a conversation you are part of without telling the others.
