Frequently asked questions

How do I check that a fire protection company in Rowland Heights is licensed?
Search the company name or license number in the California Contractors State License Board public lookup (https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/CheckLicense.aspx). Every company listed here shows its license numbers and expiration dates, re-checked against state records on each data refresh.
What license does a fire protection company need in California?

Does a company need to be located in Rowland Heights to work there?
No. California licenses are statewide, so companies based elsewhere in Los Angeles County or across California can work in Rowland Heights. Confirm the service area with the company.
