Build your inspection scheduleFrequently asked questions
- How do I check that a fire alarm company in Willis is licensed?
- Search the company name or registration number in the Texas State Fire Marshal's Office public lookup (https://appscenter.tdi.texas.gov/reports/p/sfmo). Every company listed here shows its registration numbers and expiration dates, re-checked against state records on each data refresh.
- What license does a fire alarm company need in Texas?
- Companies doing this work must hold a Texas SFMO Fire Alarm Certificate of Registration (ACR). 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 hold SFMO licenses.
- Does a company need to be located in Willis to work there?
- No. Texas registrations are statewide, so companies based elsewhere in Montgomery County or across Texas can work in Willis. Confirm the service area with the company.
