California Security Guard Services That Protect What Matters
Licensed armed and unarmed security guards, construction site security, healthcare security, and mobile patrol for businesses across California. A real person answers 24/7, and coverage often starts the same day.

Security. Safety. Compliance. Continuity.
Every California security guard services program we build stands on four pillars.
Always one step ahead
We protect your people and property 24/7 with licensed officers working from a written post order built for your site. GPS-verified patrols and daily reports mean we don’t just respond. We anticipate risks and give you a clear record of every shift.
People come first, every shift
A safe property starts with officers who see risk before it becomes an incident. Our teams are trained to spot hazards, de-escalate conflict, and respond calmly, protecting your employees, tenants, and visitors while keeping your environment professional.
We keep you on the right track
Navigate complex regulations with ease. As a BSIS-licensed operator (PPO #15857), fully insured, we support you in meeting legal and insurance requirements with audit-ready documentation that protects your operation and your reputation.
Your business runs without interruption
One partner, one fixed rate, and no unexpected surprises. Built-in backup coverage and 24/7 supervision keep every post staffed, so you can focus on what really matters: your business, today and in the future.

California security guard services FAQ
Straight answers about pricing, licensing, coverage areas, and how fast we can start.
What security guard services do you provide in California?
We provide armed and unarmed security guards, construction site security, fire watch, mobile patrol, access control, event security, lobby and concierge officers, parking lot security, and emergency short-term coverage for commercial properties across California.
Do you provide construction site security and fire watch?
Yes. We provide overnight, weekend, and 24/7 construction site security guards, plus fire watch guards for fire alarm outages, sprinkler impairments, and hot work, with time-stamped patrol logs for inspectors and insurers.
My last security company kept sending different guards who didn’t know the property. How is this different?
Officers are assigned to your property rather than to open shifts, with site-specific orientation before their first day. They already know your access points and expectations instead of learning on the job.
I call my current provider and get bounced around. What’s different here?
Every account gets a named field supervisor and a direct management contact, day or night. You’re never routed through a call center trying to figure out who handles your property.
How do I know my guards are actually doing their patrols?
GPS attendance verification, patrol tracking, and daily activity reports give you a documented record of what happened on your property, rather than relying on a guard’s word for it.
Do I need armed or unarmed officers?
It depends on your risk level, hours of operation, and how much public interaction the site sees. We’ll walk through your property with you and recommend what actually fits.
How much does a security guard cost in California?
Cost depends on armed or unarmed coverage, hours per week, location, and the length of the assignment. We provide a written, fixed-rate quote before coverage starts, with no hidden fees. Call 888-251-6607 or request a quote on this page.
Can you cover us on short notice if our current provider falls through?
Often, yes. We regularly step in for properties dealing with no-shows, sudden vendor issues, or urgent coverage gaps. Call 888-251-6607 and we’ll tell you honestly what’s possible for your timeline.
Is Premier Nationwide Security licensed and insured?
Yes. We’re licensed under California BSIS as a Private Patrol Operator, PPO #15857, and fully insured, with a certificate of insurance available on request. You can verify that license directly with the state.
Have you actually been doing this a while, or are you new?
We’ve been serving California properties since 2007. Long enough to have seen almost every situation a property can run into, and to have built our processes around handling them well.
What areas of California do you actually cover?
We’re headquartered in Los Angeles and cover Los Angeles County, Orange County, Riverside and San Bernardino Counties, San Diego County, Sacramento, and the San Francisco Bay Area, including Alameda and Contra Costa Counties. If you’re elsewhere in California, reach out. We may still be able to help.
I need coverage soon. How fast can you actually start?
It depends on your location, schedule, and how many officers you need, but we’ll give you a real timeline, not a runaround. A real person answers 24/7. For anything urgent, call 888-251-6607 directly.
