Unarmed officers licensed by the Bureau of Security and Investigative Services (BSIS) for company headquarters, multi-tenant towers and business parks across Southern California. They run the lobby, check badges, control the dock and walk the floors after hours.
Corporate office and high-rise security guards do the same core work for different clients. At a company headquarters the officer answers to your facilities lead or HR and learns employees by face. In a multi-tenant tower the client is the property manager and chief engineer, and the officer deals all day with tenants, couriers, contractors and movers. In a business park the ground spreads across several low buildings and shared parking, so patrol matters more than one lobby desk.
Most office losses involve people who already have some access, such as an ex-employee whose badge still works or a contractor who leaves with a monitor. CAL Security Group staffs these posts in Los Angeles, Orange, Ventura and San Bernardino counties and the San Fernando Valley.
Office losses rarely look like a break-in. They look like normal traffic until someone checks.
A staffed lobby by day, lighter coverage at night.

The client, the hours and the hard parts differ by building.
One employer, one badge system. The officer checks every badge at the main door, runs visitor passes, stands by at terminations and checks outgoing equipment against signed property passes.
The console is usually staffed at all hours. Visitor check-in for every tenant, couriers routed to the dock, each tenant's after-hours list, freight bookings, and stairwell checks from roof to garage overnight.
Several buildings, shared lots and no single front door. A rover or vehicle patrol checks suite doors, loading areas and parking, answers tenant calls under the post orders, and logs vehicles left overnight.
Sweeps of doors, IT closets and mechanical rooms, cleaning crews signed in, late workers checked against the access list. Offices with a staffed reception desk often need an officer only for these hours.
We write them with your facilities, HR or property lead, and brief the officer before the first shift.
Badge rule. Who gets a temporary badge, who approves it and when it expires.
Barred-persons list. Names and photos from HR, and the exact steps when one of them shows up.
Termination standby. Where the officer waits, who does the talking and which exit the employee uses.
Tenant lists. A current after-hours list and an emergency contact for each suite.
Dock and contractors. Delivery hours, certificate of insurance on file, keys out and back.
Fire alarm steps. In the City of Los Angeles, Fire Code Section 57.408 requires each high-rise to keep an emergency plan with a Fire Safety Director and floor wardens. The post orders put the officer under that plan.
The shift report flags propped doors, tailgating, failed badge readers, stairwell doors that do not latch, trouble signals on the fire alarm panel and after-hours entries by name. Since July 1, 2024, most California employers must keep a written workplace violence prevention plan and a violent incident log under Labor Code Section 6401.9 (see Cal/OSHA guidance). A report with the time, place and facts of each incident feeds that log.
