What Can a Security Guard Actually Do in California?

Learn what California security guards are legally authorized to do — arrest powers, force continuum, private property authority, and what guards CANNOT do.

One of the most common questions new security guards have is: "What am I actually allowed to do?" California law gives security guards specific authority — but also clear limitations. Understanding both is critical to staying legal and protecting yourself from liability.

Arrest Powers: Citizen's Arrest (Penal Code 837)

California security guards have the same arrest powers as any private citizen under Penal Code 837. You can make a citizen's arrest when:

**A felony has been committed** and you have reasonable cause to believe the person committed it

**A misdemeanor is committed in your presence** (you witnessed it directly)

This is often called "Powers to Arrest" — the core of your 8-hour pre-assignment training.

Critical rule: You must have actually witnessed the crime or have strong reasonable cause. Arrests based on suspicion alone can lead to lawsuits.

The Force Continuum

California expects security guards to use the minimum force necessary. The typical force continuum is:

**Verbal commands** — Ask the person to stop, leave, or comply

**Soft physical control** — Guiding, escorting, or blocking

**Hard physical control** — Restraining or defensive techniques

**Intermediate weapons** — Baton, OC spray (requires additional permits)

**Deadly force** — Only when there is an imminent threat of death or serious bodily harm

Important: Deadly force is almost never justified for security guards. Unlike police officers, guards do not have qualified immunity.

Authority on Private Property

On private property where you're authorized to work, security guards can:

Ask someone to leave (trespassers under PC 602)

Deny entry to restricted areas

Detain someone for a reasonable time if you witnessed a crime (shoplifting, trespassing, assault)

Contact law enforcement and hand off the situation

Document incidents through observation and report writing

Monitor surveillance equipment and patrol the property

What Security Guards CANNOT Do

This is equally important. California security guards cannot:

Identify themselves as police or law enforcement (PC 538d — impersonation is a crime)

Carry a firearm without a BSIS Firearms Permit

Carry a baton without a BSIS Baton Permit

Search someone's person without consent (no pat-downs unless consented)

Use excessive force — you are civilly and criminally liable

Make arrests based on race, gender, or appearance (profiling)

Enter a private residence without permission

Enforce traffic laws on public roads

Issue citations or tickets
