Frequently asked questions

How do I check that a fire protection company in Spring Valley 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.

Does a company need to be located in Spring Valley to work there?
No. California licenses are statewide, so companies based elsewhere in San Diego County or across California can work in Spring Valley. Confirm the service area with the company.
