How do I check that a fire protection company in Rancho Santa Margarita is licensed?

Does a company need to be located in Rancho Santa Margarita to work there?
No. California licenses are statewide, so companies based elsewhere in Orange County or across California can work in Rancho Santa Margarita. Confirm the service area with the company.
