Frequently asked questions

How do I check that a fire protection company in San Antonio is licensed?

Search the company name or registration number in the Texas Department of Insurance State Fire Marshal's Office lookup (https://appscenter.tdi.texas.gov/reports/p/sfmo). Every company listed here links to its registration numbers and expiration dates, re-checked against that lookup on each data refresh.

What license does a fire protection company need in Texas?

Texas requires a State Fire Marshal's Office certificate of registration for each type of work: fire alarm (ACR), fire extinguisher (ECR) and fire sprinkler (SCR). Individual technicians must also be licensed.

Does a company need to be located in San Antonio to work there?

No. Texas registrations are statewide, so companies based elsewhere in Bexar County or across Texas can work in San Antonio. Confirm the service area with the company.
