It’s 11 PM, and you’re patrolling a retail complex car park when you watch someone smash a car window and reach inside.
There are no police nearby, and no one else is around, so what do you do?
More importantly, what are you legally allowed to do?
Observe from a distance and call the police?
Issue a verbal command telling them to stop?
Intervene and attempt to detain them?
Announce they are under arrest and handcuff them?
Do you know the answer?
Whether you’re working toward your license or have been in the field for years, you need a clear understanding of the limits of your authority, as acting unlawfully can cost you your job and lead to civil claims or serious criminal charges.
In this guide, we’ll break down whether security guards can legally make arrests, how those powers can differ from state to state, the key laws every guard should be familiar with, and how to learn what your rights and legal limits are.
Do Security Guards Have the Power to Arrest?
Yes, security guards have some power to arrest, but not in the same way as police. State laws have established legal limitations for making arrests, and in most states, guards are limited to citizen’s arrests and detainment.
Security guards do not have the same legal authorities as law enforcement officers.
Instead, you are generally treated as a private citizen, and the same legal rules that apply to any member of the public also apply to you in many situations, including matters involving arrest authority.
What Is a Citizen’s Arrest?
A citizen’s arrest is a legal power that, in limited situations defined by state law, allows a private person (including security guards) to take someone into custody after personally witnessing a crime.
The key word there is witnessed.
In most states, a citizen’s arrest is lawful only when the person making the arrest directly observed the crime in progress. If you’re just suspicious of someone or have been told by another person that they have seen a crime, you are not permitted to make a citizen’s arrest.
Citizen’s arrest laws also vary from state to state. Some states allow them only for felonies, while others permit them for misdemeanors committed in your presence.
Detainment vs. Arrests
There’s a big difference between detaining someone and arresting them.
- Detention: When you detain someone, you’re not taking them into custody. Instead, you’re briefly holding them while you gather information or wait for the police to arrive.
- Arrest: Arresting someone means taking them into full custody and restricting their freedom of movement on the belief that they committed a crime.
How Security Guard Arrest Powers Vary by State
The United States has no single federal standard for citizen arrest powers.
What you can legally do in Texas may be completely different from what you can do in California, and you need to understand the rules that apply in the state where you’re working.
Unlike police officers, who operate under a mix of federal constitutional law and state statutes, security guards have no federal framework governing their arrest powers.
Instead, every state has developed its own laws and regulations around what security guards can and cannot do.
Guards who move between states or work for national companies are the ones most likely to unintentionally overstep their authority. If you assume the rules are the same everywhere, you could easily make an arrest that violates state law.
States With More Permissive Laws
Some states give security guards greater authority to act:
- In Texas, citizen’s arrest law allows private individuals, including security guards, to arrest someone who commits a felony or breach of the peace in their presence.
- Tennessee law permits citizen’s arrest in cases involving felonies and offenses committed in a person’s presence. The state also recognizes strong protections for shopkeepers in retail environments, which can give guards more authority to detain suspected shoplifters.
States With Tighter Restrictions
Other states have significantly narrowed what security guards and private citizens can do:
- California is one of the most restrictive states for private security. Citizen’s arrest is permitted per Penal Code 837, but comes with strict conditions, and guards who overstep face serious civil and criminal consequences. California has also recently increased regulations governing licensed security personnel, raising the bar for who can work in the field and under what conditions.
- Georgia changed its citizen’s arrest law in 2021 after the Ahmaud Arbery case and now significantly limits when a private person can detain someone.
States That Name Security Guards Explicitly
Some states specifically address security guards in their statutes:
- Oregon has statutes that specifically reference the authority of private security providers, outlining detention rights and the conditions under which they apply.
- Nevada, given its large private security industry driven by the casino and hospitality sectors, grants guards specific authorities that are not available to a typical private citizen.
Key Laws Every Security Guard Should Know
You don’t need a law degree to work in private security, but you do need a working knowledge of key laws that can affect your day-to-day duties:
1. Use of Force Laws
Security guards do not have unrestricted authority to use force, and this is one of the most common areas where legal boundaries are crossed.
In most states, the governing standard is reasonable force, meaning the level of force you use must match the level of threat you’re facing at that moment.
It should be no more than what a typical person would consider reasonable to control the situation or mitigate the risk.
What to keep in mind:
- Deadly force is generally limited to situations involving an immediate threat to life, usually in self-defense or defense of others.
- Force is no longer justified once the threat has ended, and continuing physical action after someone is compliant may be treated as assault.
- Employer instructions don’t override the law, and your company’s policy can’t justify actions that exceed legal limits.
- Use-of-force incidents are closely reviewed, and you’ll need to clearly explain why the level of force used was necessary in that moment.
If you’re uncertain about how much force you can use in a situation, it’s best to disengage completely and call law enforcement.
2. False Imprisonment
False imprisonment is where a person is unlawfully restricted from leaving a place against their will, and it is a common claim brought against security guards.
False imprisonment doesn’t require physical restraint. It can happen whenever someone’s freedom of movement is intentionally restricted without proper legal justification, such as blocking an exit or making it clear they are not free to leave.
Security guards can reduce exposure to false imprisonment claims by making sure there’s a valid legal basis for detention (such as a witnessed offense).
You should also keep your conduct reasonable throughout the interaction, limit how long someone is held, avoid intimidation or coercive language, and use only the level of force required for the situation.
Holding someone longer than the situation calls for or treating them in a disrespectful or humiliating way can put you at serious legal risk, even if it later turns out the person did commit a crime.
3. Trespassing Authority on Private Property
Security guards can act on behalf of the property owner when assigned to protect private property. This generally includes the ability to direct individuals to leave if they do not have permission to be there.
However, you cannot physically remove someone just for trespassing. In most states, trespass on its own does not justify physical detention, and your authority is often restricted to issuing a warning and documenting the situation.
You might also choose to contact law enforcement if the person refuses to leave, depending on the circumstances and your post orders.
4. Shopkeeper’s Privilege
In some industries, a guard’s legal authority changes depending on the environment where they are posted and the client’s internal policies.
Retail loss prevention is the most common example. Many states recognize shopkeeper’s privilege laws that allow retail staff, including security personnel, to briefly detain a person suspected of theft, even when the full requirements for a citizen’s arrest are not met.
This authority generally depends on probable cause that a theft occurred, a brief and reasonable detention, and conduct that avoids intimidation or degrading treatment.
How to Learn Your Rights as a Security Guard
If you want to build an understanding of your legal responsibilities and limits in the field, here’s where to start:
Complete Your State’s Licensing Requirements and Training Curriculum
Your state’s licensing process is the first place your legal education should begin.
Most states that require security guard licensing mandate a minimum number of training hours before you can begin working. That curriculum typically includes information covering citizen’s arrest, use of force, limits of your authority, and other legal topics.
After you complete this training, you’ll have at least general knowledge about your state’s laws regarding security guard arrests.
Refer to Your State’s Licensing Board
If, after your mandatory training, you feel uncertain about specific rules or find that details have become unclear over time, you can use your state’s licensing board resources to verify the correct information.
These boards exist to regulate the profession, and they publish the rules security personnel are expected to follow.
Most state boards maintain publicly accessible documentation that includes licensing requirements, approved training providers, relevant statutes, and more.
Take Online Courses
One of the most practical ways to build legal knowledge on your own schedule is through online courses designed specifically for working guards and aspiring professionals.
Some courses we offer at GuardTraining that will help you learn about laws and rights as a security guard include:
- Liability & Legal Aspects covers how the legal system applies to security work, including distinctions between criminal and civil law, powers of arrest, and liability risks. It provides information about vicarious liability and practical guidance on staying compliant and handling legal disputes.
- Arrests, Searches, and Seizures covers Fourth and Fifth Amendment protections, arrest authority, searches, and evidence handling. You’ll also learn about shopkeepers’ privilege, false imprisonment, and liability for excessive force.
- Appropriate Use of Force explains what “reasonable force” means under the law and how the force continuum applies in different situations. It also covers the legal implications of arrests and detainment, de-escalation techniques, less-lethal alternatives, and the liability concerns that follow any use-of-force incident.
Use Your Employer’s Resources
Your employer has a strong interest in making sure you don’t overstep your authority, because when you do, they could be liable too.
Many security companies will have legal resources and written policies you can request and refer to. If you’re unsure about a specific legal boundary or law, don’t hesitate to ask your supervisor directly.
Some employers and clients also prohibit any physical contact by security personnel under any circumstances, so if you’re starting a new role or have been assigned to a new site, make sure you know the exact rules in advance.
Tip: Be sure to read every policy document provided by your employer, as many new guards skim through them or overlook them entirely. These documents set the legal boundaries of your role on that assignment, and stating that you did not review them will not serve as a defense.
Become the Most Knowledgeable Guard on Your Team
When conducting your duties, always remember that if you exceed your legal authority when making a citizen’s arrest or detaining someone, you can land yourself in serious trouble with your employer and the state.
Be sure to use all the resources and help available to you to stay within the law when acting in any on-duty situation.
