Low-voltage licensing
Texas
Texas requires a state-issued license for low-voltage work through the Texas Department of Licensing and Regulation (TDLR). Two main classifications apply: Electrical Contractor (Master) for general electrical and Electrical Sign Contractor, plus the Electrical Apprentice tier. A separate Fire Alarm License is required for any fire-alarm work, and Locksmith / Security Services licenses cover access control and intrusion alarms.

Common pitfalls
Mistakes we see installers make when navigating Texas licensing.
- An Electrical Contractor license requires you to designate a Master Electrician who acts as the responsible party. Without one, the business license cannot be issued.
- Fire alarm work requires a separate Fire Alarm License through TDLR's Fire Alarm program, NOT the Electrical license.
- Security camera and access control installation may require a Private Security Bureau (PSB) license through the Texas DPS, not TDLR.
- City permits are still required on top of the state license for most municipalities.
Reciprocity
Texas has limited reciprocity with Arkansas, Oklahoma, Louisiana, North Carolina, and a few others for the Master Electrician exam only - it doesn't transfer the business Electrical Contractor license.
