Who regulates private investigators in Louisiana
The LSBPIE licenses individual investigators, apprentices and agencies under the Private Investigators Law, Louisiana Revised Statutes Title 37, Chapter 56, and its rules in the Louisiana Administrative Code (Title 46, Part LVII).

Armed work requires a separate firearm qualification under the Board’s rules, according to industry guides. Confirm the training and qualification requirements with the LSBPIE before carrying on duty.
What a private investigator in Louisiana can and can’t do
A PI license is a business license, not police authority. In Louisiana, as everywhere in the U.S., private investigators generally cannot:
- Impersonate law enforcement or claim official authority.
- Trespass on private property to watch or photograph someone.
- Obtain bank, phone or other protected records by pretexting, which federal law prohibits.
- Hack accounts, read someone else’s email or install spyware.
- Place a tracking device on a vehicle where state law forbids it.
- Detain or arrest anyone beyond the citizen’s arrest rights every person has.
On recording, Louisiana is not on the list of all-party consent states in a 2024 legal summary by the law firm Kilpatrick, which generally means one party to a conversation can record it. That does not allow recording conversations you are not part of, and other privacy laws still apply.
