Frequently asked questions
- How do I check that a fire protection company in Houston 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 Houston to work there?
- No. Texas registrations are statewide, so companies based elsewhere in Harris County or across Texas can work in Houston. Confirm the service area with the company.
