How Licensing Works in Maine
Maine regulates private security and private investigation through separate statutory chapters within Title 32. Security services are regulated under Title 32, Chapter 93 (Private Security Guards). Private investigation services are regulated under Title 32, Chapter 89 (Professional Investigators).
Licensing is administered by the Maine State Police Special Investigations Unit. The statutory structure distinguishes between company licensing for contract security companies and individual licensing for security guards and investigator roles.
Maine operates as a centralized, statewide licensing regime.

Maine separates private security and private investigation into different statutory chapters. Firms should confirm whether they require a company license, individual licenses, or both, based on the role and service model.
