How to Choose the Right Security Guard Company in Los Angeles
Before signing with any security provider in Los Angeles, evaluate them against these critical criteria.
1. Verify BSIS Licensing
Every security company and individual guard operating in California must be licensed by the Bureau of Security and Investigative Services. Check the company license and confirm each deployed guard carries an individual Guard Card. Verify both on the California Department of Consumer Affairs website.
2. Confirm Insurance Coverage
Request a certificate of insurance showing general liability coverage. The minimum is $1 million. The best providers, like OnGuard, carry $1.5 million. Never work with an uninsured security company — your business inherits the liability.
3. Assess Local Experience
Los Angeles is a large, complex market with distinct neighborhoods, industries, and crime patterns. Choose a company with demonstrated local experience, not one applying a national template to an LA context.
4. Ask About Contract Terms
Long-term contracts benefit the security company, not you. Ask about minimum commitments, cancellation provisions, and rate-lock terms before signing. OnGuard requires no long-term contracts.
5. Evaluate the Supervision Structure
Ask how guards are supervised, how incidents are documented, and who your escalation contact is. A dedicated supervisor assigned to your account — not a call center — is what professional service looks like.
6. Request a Site Assessment Before Committing
Any serious security company will visit your property before proposing coverage. A written proposal based on a physical site visit reflects actual understanding of your needs. OnGuard provides this at no charge.
Why Hiring Professional Security Matters in Los Angeles
Los Angeles consistently ranks among the top U.S. cities for commercial property crime. According to the Los Angeles Police Department’s 2023 Annual Report, property crime accounted for over 80% of all crimes reported citywide. Professional security guards do far more than fill a post — they actively deter incidents, manage access, respond to emergencies, and protect your employees, customers, and assets.
Key Benefits Include:
- Visible deterrence that reduces property crime incidents
- Rapid response to security events before they escalate
- Professional access control that protects your facility
- Documented incident reporting that supports liability management
- Peace of mind for employees, tenants, and customers
The ASIS International 2022 Security Industry Benchmark Report found that properties with professional uniformed security experienced 30 to 50 percent fewer reported property crime incidents compared to comparable unguarded properties.
Frequently Asked Questions
How much does it cost to hire a security guard company in Los Angeles?
Costs typically range from $20 to $50 per hour depending on whether the guard is armed, the level of training required, and the complexity of the assignment. OnGuard provides a written proposal with clear pricing following a free on-site assessment.
What is the difference between armed and unarmed security guards in LA?
Armed guards carry firearms and hold a BSIS Firearm Permit in addition to their Guard Card. They are deployed for high-risk environments. Unarmed guards handle the majority of commercial, retail, and event security needs effectively and are appropriate for most Los Angeles business environments.
Do security companies in Los Angeles provide 24/7 services?
Yes. Top providers like OnGuard offer round-the-clock security coverage including 24/7 dispatch and surveillance capability. Coverage hours are defined in your service agreement and can be adjusted as your needs change.
Can I hire a security guard company for a one-day event in Los Angeles?
Yes. Most professional Los Angeles security companies offer short-term and event-based security. OnGuard handles event security for everything from corporate functions to large public gatherings throughout LA County.
How do I verify a security company is licensed in California?
Check the company’s BSIS license number through the California Department of Consumer Affairs at dca.ca.gov. You can verify both the company license and individual guard Guard Cards through the same portal.
What industries require security guards most in Los Angeles?
Construction, retail, corporate offices, healthcare, entertainment, residential, and industrial/logistics operations all have high security guard demand in Los Angeles. OnGuard serves all of these sectors across LA County.
Are mobile patrol services better than static guards for LA properties?
It depends on your property type. Mobile patrols are more cost-effective for large campuses, industrial parks, and HOA communities. Static guards are better for fixed access control points, lobbies, and high-foot-traffic locations. Many properties use both.
How quickly can a security company deploy guards in Los Angeles?
Top companies like OnGuard can typically deploy within 24 to 48 hours for standard engagements. Emergency deployments for urgent situations can often be arranged within hours depending on guard availability and location.
Do Los Angeles security guards handle emergency situations?
Yes. Trained guards respond to security incidents, manage access during emergencies, coordinate with LAPD and emergency services, and document all incidents in written reports. OnGuard guards receive training in emergency response protocols.
What should I look for in a Los Angeles security guard contract?
Review service specifications, guard licensing requirements, supervision structure, incident reporting procedures, insurance coverage, pricing structure, and cancellation terms. OnGuard operates without long-term contracts, giving you flexibility other providers do not offer.
