TDLR
The Texas Department of Licensing and Regulation (TDLR) is the Texas state agency that licenses and regulates a wide range of trades including HVAC, electrical, plumbing, and building contractors.
TDLR oversees approximately 280,000 contractor licenses and maintains a public license lookup database. Texas uses a decentralized licensing model — some trades are licensed at the city level in addition to state level.
