What Security Guards Can and Can’t Do in California: A Complete Legal Guide
Learn what security guards can and can’t do in California, including updated guard card duties, legal limits, and compliance needs. Stay audit-ready with Belfry.
Understanding what security guards can do in California is one of the most important responsibilities of running a compliant and reputable security company. California has some of the most clearly defined and strictly enforced regulations governing private security operations, and even minor missteps can expose your business to legal risk.
Security guard authority is governed primarily by the Bureau of Security and Investigative Services (BSIS) under the California Department of Consumer Affairs, along with several applicable sections of the California Penal Code. These laws define what guards are allowed to do, where their authority ends, and how they must conduct themselves while on duty.
This guide provides a clear, practical breakdown of the law so you can train your officers properly, protect your clients, and scale your operations with confidence.
The Role of a Security Guard in California
Under California law, a licensed security guard is a private person, not a peace officer. Their authority is limited, property-specific, and regulated by BSIS.
According to California Business and Professions Code §7582.1, licensed security guards are permitted to protect persons and property, but only within clearly defined boundaries.
The core California guard card duties fall into three categories:
Observation and Reporting
Security guards are authorized to observe activities on the property they are assigned to protect and document anything suspicious, unsafe, or unlawful. This includes monitoring surveillance systems, foot traffic, access points, and alarms.
Under BSIS guidelines, guards must accurately document incidents and report criminal activity to law enforcement rather than attempt to resolve crimes independently.
Protection of People and Property
Guards may take proactive steps to prevent theft, vandalism, trespassing, or violence. This can include controlling access points, conducting patrols, de-escalating disputes, and securing areas during emergencies.
However, all actions must remain proportional, reasonable, and consistent with company policy and state law.
Acting Within Legal Limits
Security guards must always operate within the authority granted by BSIS and the California Penal Code. Any action taken outside these limits can result in civil liability, criminal charges, license suspension, or revocation.

What Security Guards Can Legally Do in California
To fully understand what security guards can do in California, it’s essential to look at the specific powers granted under state law and BSIS regulations.
Can Security Guards Carry Weapons in California?
A common question among operators is ‘can security guards carry guns in California’. The answer is yes, but only with proper authorization.
Under Business and Professions Code §7583.23, a security guard may carry a firearm only if they possess:
- A valid Guard Card
- A BSIS Firearm Permit
- Proof of employer authorization
- The firearm permit requires:
- An 8-hour BSIS-approved firearms training course
- A psychological assessment
- A written exam
- A live-fire range qualification
Additional weapon permits include:
- Baton Permit (8-hour BSIS-certified training)
- OC / Pepper Spray Certification
Firearms are typically authorized in high-risk assignments such as:
- Cash and valuables transport
- High-value commercial properties
- Executive or personal protection
- Patrol operations in high-crime areas
Guards may only carry approved weapons while on duty and assigned to an authorized post.
Before exercising any authority, guards must be properly licensed. Learn more in our complete guide: California guard card: how to get it and renew it.
Requesting Identification on Private Property
Security guards working on private property may legally request identification to:
It's essential to train your guards on the proper way to ask for ID and to emphasize that they cannot compel someone to show it unless they're suspected of a crime. Clear communication and de-escalation techniques are crucial in these situations.
- Verify age for restricted venues
- Confirm authorization to enter
- Investigate suspicious behavior
However, guards cannot force someone to provide ID unless a crime is reasonably suspected. This limitation is critical to preventing unlawful detentions or civil rights violations.
Training should emphasize calm communication, professional demeanor, and de-escalation techniques.
Observation, Reporting, and Documentation
BSIS places strong emphasis on documentation and accountability. Guards should be trained to identify and record:
- Trespassing or loitering
- Forced entry or property damageOpen doors or windows, signs of forced entry, or damage to buildings or equipment.
- Unauthorized access attempts
- Escalating verbal disputes
Incident reports should always include time, date, location, involved parties, and actions taken. These records may later be used in insurance claims, court proceedings, or compliance audits.
Modern security guard software significantly improves accuracy and timeliness by allowing officers to submit reports digitally in real time.
Maintaining Logs and Records
Accurate record-keeping is not optional; it is a compliance requirement.
Guards must maintain shift logs documenting patrols, incidents, and responses. Many security companies now rely on guard management software to standardize reporting, reduce errors, and maintain audit-ready records
Platforms like Belfry allow officers to submit reports directly from mobile devices, ensuring documentation is time-stamped, consistent, and immediately accessible.
Protecting Property and Detaining Suspects
Security guards may:
- Control access points
- Verify credentials
- Conduct mobile patrols
- Use physical barriers to restrict entry
In cases of theft, vandalism, or trespassing, guards may detain a suspect only under the rules of a citizen’s arrest, discussed below. Any force used must be reasonable and proportionate.
What Security Guards Can’t Do in California
Understanding what security guards can’t do in California is just as important as knowing their permitted actions.
Use Excessive Force
Under California Penal Code §835a, force must be objectively reasonable. Security guards are not allowed to use force as punishment or retaliation.
Force may only be used to:
- Prevent imminent harm
- Stop a crime in progress
- Protect themselves or others
Guards must always use the minimum force necessary to achieve lawful objectives.
Conduct Searches Without Consent
Private security guards generally do not have search authority. This includes:
- Pat-downs
- Bag inspections
- Vehicle searches
Unless consent is given, guards must refrain from searching and instead deny entry or contact law enforcement if necessary.
Make Police-Style Arrests
Security guards do not have police arrest powers. The arrest powers of security guards are limited to the citizen’s arrest authority under California Penal Code §837.
A citizen’s arrest is only lawful if:
- The guard personally witnesses the entire crime
- The offense is a felony or misdemeanor
- The arrest occurs on the property they protect
Guards must never say “you are under arrest” or represent themselves as law enforcement.
Act Outside Assigned Property
A guard’s authority is limited to the site they are contracted to protect. Pursuing suspects off-property is not permitted.
If an incident moves beyond the premises, guards should observe, document, and relay information to police.
Scenario-Based Guidelines for Guards
Interactions on Private Property
Guards may request ID, address, and disruptive behavior, and ask individuals to leave. If someone refuses after being informed of trespassing laws, detention may be lawful while awaiting police, provided all legal requirements are met.
Emergency Situations
- Fire: Evacuate immediately and contact emergency services
- Medical: Call EMS and provide first aid if trained
- Active Threat: Follow emergency response plans and contact 911
Citizen’s Arrest: Legal Requirements and Risks
All California guards must complete the BSIS Power to Arrest training.
Guards should understand that citizen’s arrests carry significant legal risk and should only be used when absolutely necessary. De-escalation and observation should always be the preferred response.
