How to become a security guard in Maine

Last reviewed August 28, 2026 · Regulator: Maine State Police — Special Investigations Unit

Maine licenses contract security companies, not individual guards. Guards must meet statutory qualifications (18+, citizen or resident alien, clean record), and employers must report each guard to the Commissioner of Public Safety and complete a background investigation within 60 days.

Steps to get started

  1. Get hired by a licensed Maine contract security company.
  2. Meet the statutory qualifications in 32 M.R.S. §9410-A (age, citizenship/residency, criminal and military record standards).
  3. Your employer reports you to the Commissioner of Public Safety before your first shift and completes a background investigation within 60 days.
  4. Complete any training your employer requires — Maine sets no statewide hour minimum.

Armed assignments require the employer to submit the completed background statement to the Commissioner before a guard may carry a firearm on duty; training is set by the employer under state oversight.
