Maine Security Guard License Requirements

Maine licenses contract security companies, not individual security guards. Under the Private Security Guards Act (32 M.R.S. Chapter 93), administered by the Maine State Police, employees of a licensed contract security company do not get their own license, but they must meet minimum qualifications set by statute, and the company must report each new guard to the State Police and complete a background investigation. Maine sets no state training hours for guards. This guide explains the employee qualifications, what your employer must do, firearms rules (including a special rule for strike sites), and your legal authority.

How Maine regulates security work

Under 32 M.R.S. §9404, no person may act as a security guard without the commissioner’s license to be a contract security company. Employees of a licensed contract security company, and proprietary (in-house) security organizations and their employees, are exempt from licensing. In practice, that means contract guards work under the company’s license, and in-house guards at hospitals, mills or retailers follow their employer’s standards.

	Contract security guard (employee)	Contract security company	In-house (proprietary) guard
License	None (works under company license)	Required ($400 original, $200 yearly renewal)	None
Qualifications	Statutory minimums (§9410-A)	Statutory and licensing standards	Set by employer
Background check	By the company, reported to State Police	By State Police	By employer

Employee qualifications

Under 32 M.R.S. §9410-A, a contract security guard must:

• Be at least 18.
• Be a U.S. citizen or resident alien.
• Not have been dishonorably discharged from the military within the past 5 years.
• Not have been convicted of a crime punishable by one year or more of imprisonment (for certain crimes listed in §9412, the bar applies for 5 years), and not have an equivalent juvenile adjudication.
• Not have three or more convictions for crimes punishable by less than one year within the past 5 years.
• Not be a fugitive from justice.
• Not be a drug user or have a substance use disorder.
• Not be potentially dangerous to self or others because of a mental disorder.
• Not have a guardian or conservator (unless terminated).

What your employer must do

• Notify the State Police before you start work, with your full name, current address, addresses for the past 5 years, date and place of birth, height, weight and eye color.
• Investigate your background to confirm you meet the qualifications. For most guards, the investigation must be completed within 60 days after you start, and a signed statement submitted to the commissioner.
• Complete the investigation before you start if you will work at a labor dispute or strike site.
• Hold a company license and a bond ($10,000 resident, $50,000 non-resident), and post the license at its principal office.

The State Police can obtain relevant records at the company’s request, including court, law enforcement, military and certain mental health commitment records.

Training

Maine’s statute does not set training hours for security guards. Employers train you on post orders, patrol, report writing, emergency procedures and the limits of your authority, and many clients require more, such as first aid, CPR and AED or de-escalation. Because there is no state course, ask exactly what training you will get before your first post.

Firearms

Maine has no separate state armed-guard license. Key rules in the Private Security Guards Act:

• You may not wear, carry or use a firearm while performing security duties until your employer’s signed background statement has been submitted to the commissioner (§9410-A).
• Guards may carry a loaded, unconcealed weapon in a motor vehicle used for armored car service or transporting things of value (§9416).
• Being armed with a dangerous weapon at a labor dispute or strike site is a crime, except to the extent federal law requires it. A concealed carry permit does not exempt you (§9412).

Maine allows permitless concealed carry for most adults 21 and older (and for some younger service members and veterans) who may legally possess firearms, and it still issues concealed handgun permits. Employers set firearms training and qualification standards for armed posts. Get your employer’s policy in writing.

Your authority in Maine

Security guards have no police powers. Under Maine law (17-A M.R.S. §16), a private person may arrest someone they have probable cause to believe has committed or is committing certain serious crimes, or certain crimes in their presence, and may use reasonable nondeadly force to do so, with significant legal risk if they are wrong. Maine also protects merchants and their employees who detain suspected shoplifters with probable cause, in a reasonable manner and for a reasonable time. Your post orders are usually stricter. Write a report every time you act.

How to start working security in Maine

1. Check your record against the qualifications above.
2. Apply to licensed contract security companies or in-house security departments.
3. Provide the information your employer must report to the State Police before your first shift.
4. Complete the employer’s training and site orientation.
5. Do not carry a firearm on duty until your employer confirms the background statement has been filed and you meet its firearms requirements.

Costs

There is no state fee for individual guards. The company pays its own license fees ($400 for an original license and $200 for yearly renewal) and bond. Your costs are usually limited to optional certifications and, for armed work, firearms training and equipment if the employer does not provide them.

Choosing an employer in Maine

Ask whether the company is licensed by the Maine State Police, how it handles the 60-day background investigation, what training it provides before your first post, and whether posts are observe-and-report. Security jobs are concentrated in Portland, Bangor, Lewiston-Auburn and Augusta, and at hospitals, colleges, shipyards, mills, ports and seasonal tourist venues. Winter posts are cold and dark; see our cold-weather gear guide and flashlight guide.

Getting ready for your first post

Learn your post orders and emergency procedures, and practice clear reports with our incident report template. First aid, CPR and AED certification and de-escalation training are worth adding. Know the limits of your authority; our guide on detaining people covers the basics.

Strike and labor dispute assignments

Maine’s law treats labor dispute and strike sites differently from other posts, and guards should understand why. The background investigation must be finished before you work at such a site, and being armed with a dangerous weapon there is a crime except where federal law requires it. A concealed carry permit does not change that. If you are offered a strike-site assignment, confirm with your employer that your background statement has been filed, that you will be unarmed, and what your post orders say about contact with picketers. Stay neutral, observe, document and call police for any crime.

Seasonal and coastal work

Maine’s summer tourism brings demand for event, resort and venue security along the coast and in the lakes region, while ports, shipyards and paper mills need year-round officers. Seasonal posts are a good way to start, but you still need to meet the statutory qualifications and be reported to the State Police by your employer before your first shift. Year-round posts at hospitals, colleges and industrial sites usually offer better pay, benefits and training.

Questions to ask an employer

• Is the company licensed by the Maine State Police?
• Will you report me before my first shift and finish my background investigation within 60 days?
• What training will I receive before working alone?
• Is the post observe-and-report? What is your use-of-force policy?
• Do you staff strike sites, and how do you handle those assignments?

Moving to Maine from another state

There is no Maine guard license to transfer into. Your new employer reports you to the State Police and checks your background. Prior licenses and training help you get hired.
