Can an out-of-state guard company perform a one-day guard job in California?

An out-of-state guard company cannot perform a one-day guard job in California without being licensed in the state. The California Private Security Services Act requires all security personnel providing services within California to be properly licensed by the Bureau of Security and Investigative Services (BSIS). This law ensures that security personnel meet specific training, background check, and regulatory compliance standards that protect public safety.

For an out-of-state company to legally operate in California, they would need to obtain a California security guard license for their personnel, regardless of the duration of the job. As a result, the requirement for a state license applies uniformly, and the option of performing a job without it, even for just one day, is not permitted.
