TDLR (Texas Department of Licensing and Regulation)
TDLR is Texas's state licensing agency for many skilled trades. HVAC, electrical, plumbing, and other contractors may need a TDLR licence even though Texas has no statewide GC licence.
Quick definition
TDLR (Texas Department of Licensing and Regulation) means TDLR is Texas's state licensing agency for many skilled trades. HVAC, electrical, plumbing, and other contractors may need a TDLR licence even though Texas has no statewide GC licence.
What is TDLR?
TDLR (Texas Department of Licensing and Regulation) is the Texas state agency that licenses and regulates many occupations, including several construction-related trades. If you work in Texas, you will see TDLR licence numbers on trucks, bids, and inspection paperwork.
TDLR is not the same as your city building department. State trade licensing and local permits are separate checks. You may need both to work legally.
Does Texas license general contractors?
Texas does not issue a statewide general contractor (GC) licence. A company can call itself a general contractor without a single state GC credential.
That does not mean "no rules." It means compliance is a patchwork of:
- TDLR licences for regulated trades
- Local city or county permits and inspections
- Registration programs in some municipalities (for example, contractor registration in certain Texas cities)
- State registration for specialties like mold assessment or remediation in some cases
Always check the city where the job sits, not just state trade rules.
Trades commonly licensed through TDLR
TDLR oversees many programs relevant to contractors, including:
| Trade / activity | Why it matters |
|---|---|
| HVAC / air conditioning and refrigeration | Licence required for much HVAC work in Texas |
| Electrical contractor licensing | State-level electrical contractor credentials |
| Plumbing | Plumbing contractor and tradesperson licensing (TDLR took over much of this function after prior agency changes) |
| Well drilling and pump installation | Regulated contractor licensing |
| Elevator contractors | Specialized licence categories |
| Other specialty programs | TDLR administers additional trade and business licences over time |
Program names and requirements change. Verify your exact licence class on the official TDLR site before bidding regulated work.
TDLR licence vs local permit
Texas contractors often confuse these two:
| Requirement | Who issues it | What it allows |
|---|---|---|
| TDLR licence | State of Texas | Shows your business or tradesperson meets state trade licensing rules |
| Building / trade permit | City or county | Authorizes a specific scope of work at a specific address |
You can hold a valid TDLR HVAC licence and still pull no municipal permit. That is a problem. You can pull a permit and still lack the state licence for regulated work. Also a problem.
Verifying licences and complaints
Before you hire a sub or partner on a Texas job:
- Look up the licence on the TDLR license search
- Confirm the licence class matches the work (residential vs commercial categories matter on some trades)
- Check expiration and disciplinary history
Owners and GCs increasingly verify subs after bad experiences with unlicensed trades.
Insurance, bonds, and contracts
TDLR licensing does not replace:
- General liability and workers' compensation coverage
- Surety bonds required on some public or commercial jobs
- Written contracts with scope, payment terms, and warranty language
On residential work, defect claims may trigger RCLA procedures. On payment fights, you may need Texas mechanic's lien or prompt payment rules.
On the job
Put licence numbers on estimates and invoices. Commercial clients expect it on regulated trades.
Track renewals and continuing education. Lapsed licences stop jobs cold at inspection.
Know when a "handyman" job crosses into regulated work. HVAC, electrical, and plumbing lines are enforced.
Pull permits early. Texas cities differ on online permitting, plan review, and inspection schedules.
Note
This is general info, not legal advice. TDLR programs, licence classes, and local permit rules change. Confirm requirements with TDLR, your local building official, and qualified counsel for your trade and project.
