Frequently Asked Questions

Common questions about private security services in Ontario, California:

QWhat are the licensing requirements for private security guards and companies operating in Ontario, California?

In Ontario, California, all private security guards and companies must be licensed by the California Bureau of Security and Investigative Services (BSIS). Guards must complete a 40-hour training course, pass a background check, and obtain a valid Guard Card. Security companies must hold a Private Patrol Operator (PPO) license. Additionally, Ontario may have local business licensing requirements, so it's important to verify that your chosen provider is fully compliant with both state and city regulations.

QWhat types of private security services are most commonly used by businesses and residents in Ontario, CA?

In Ontario, common private security services include armed and unarmed guards for retail locations, warehouses, and distribution centers (especially near the Ontario International Airport and logistics hubs), mobile patrols for residential neighborhoods and business parks, event security for venues like the Toyota Arena or Ontario Convention Center, and access control for gated communities and industrial sites. Many local providers also offer specialized services like cargo theft prevention and construction site security, addressing the specific risks in this major Inland Empire city.

QHow much does it typically cost to hire private security services in Ontario, California?

Costs in Ontario vary based on service type, risk level, and duration. For unarmed security guards, expect to pay $25-$40 per hour. Armed guards typically range from $35-$60 per hour. Mobile patrol services might cost $45-$75 per visit. Factors influencing cost include the location's crime statistics (you can reference Ontario Police Department crime maps), required coverage hours, and any special equipment needed. Many Ontario-based companies offer customized quotes based on a free site assessment of your specific property or event needs.

QWhat should I look for when hiring a private security company in Ontario?

When hiring in Ontario, verify the company's BSIS PPO license and their insurance coverage (general liability and workers' compensation). Look for local experience—companies familiar with areas like the Ontario Mills mall, the airport logistics corridor, or downtown Ontario will understand specific security challenges. Check reviews and references from other Ontario businesses. Ensure they provide proper supervision and have clear communication protocols with the Ontario Police Department when needed. Also confirm they conduct thorough background checks on their guards, as required by California law.

QAre there any local ordinances in Ontario that affect how private security services can operate?

Yes, Ontario has local ordinances that security providers must follow. These include regulations regarding security vehicle markings and lighting, noise restrictions during nighttime patrols in residential areas, and specific requirements for security at large public events. The city also has trespassing enforcement protocols that security personnel should coordinate with property owners and Ontario PD. Some business districts and homeowners associations in Ontario may have additional security guidelines. A reputable local security company will be familiar with these municipal regulations and ensure compliance.
