Texas Contractor License Exam Guide (2026)
Texas licensing is trade-driven: the state does not issue a general contractor license, while TDLR and TSBPE license electrical, HVAC/refrigeration, plumbing, irrigation, and other specialties. Large cities still require local GC registration before you pull permits—confirm your trade board and city rules before you schedule an exam.

How Texas licenses contractors
TDLR oversees electrical and HVAC/refrigeration contractors under the Texas Occupations Code; the Texas State Board of Plumbing Examiners licenses plumbers; the State Fire Marshal licenses fire protection. Cities such as Austin, Dallas, San Antonio, and Fort Worth register general contractors with bond and insurance requirements, while Houston often relies on per-permit registration. Workers' compensation is optional for many private employers in Texas—but cities and owners still demand certificates on many jobs.
Contractors plan for extreme rooftop heat in Houston, expansive clay around Dallas, and desert wind in El Paso. Exams emphasize NEC, mechanical code, gas piping, and windstorm-resistant detailing for the Texas coast.

Texas contractor exam blueprint (verified June 2026)
Texas has no state-level general contractor license. A remodeler, framer, or roofer can legally operate statewide without a state license — but the trades below require state credentials, and most large cities require local GC registration.
| Electrical | State license — TDLR, Texas Occupations Code Ch. 1305 (Master Electrician requires 12,000 hours) |
|---|---|
| HVAC / Refrigeration | State license — TDLR, Ch. 1302 (48 months of experience; Class A/B) |
| Plumbing | State license — Texas State Board of Plumbing Examiners, Ch. 1301 (Responsible Master Plumber to operate independently) |
| Irrigation | State license — TDLR, Ch. 1903 |
| General contractor | No state license; city registration required in Austin, Dallas, San Antonio, and Fort Worth — Houston uses per-permit registration only |
What trips Texas applicants up
Searching "Texas general contractor license" sends people in circles because the state license does not exist. What you actually need is (1) the right TDLR or TSBPE trade license if you do electrical, plumbing, or HVAC work, and (2) city registration wherever you pull permits. Texas is also the only state where workers' compensation is optional for private employers.

Who needs a Texas contractor license (and who does not)
Searching for a Texas general contractor license usually means you need a city registration plus the correct trade license—not a single statewide GC credential.
| TDLR electrical / HVAC | Covers: Electrical or air-conditioning & refrigeration contracting Authority: TDLR — PSI exams + Business & Law; $300k liability minimum |
|---|---|
| TSBPE plumbing | Covers: Plumbing contracting statewide Authority: Texas State Board of Plumbing Examiners — tradesman/journeyman/master paths |
| City GC registration | Covers: General contracting, remodeling, or framing without a state trade license Authority: Austin, Dallas, San Antonio, Fort Worth (and other cities) — bonds/insurance vary |

- NEC ampacity, grounding, and Texas amendments under timed open-book conditions
- IMC/IFGC gas piping and combustion-air lookups for HVAC Class A/B paths
- TSBPE Plumbing License Law items that are statute-heavy rather than code-lookup heavy
- City bond/insurance minimums that still apply even though Texas has no state GC license
- Heat-illness and documentation habits owners expect on Texas jobsites even when WC is optional

- International Mechanical Code 2021
- Uniform Plumbing Code/International Plumbing Code (city dependent)
- Texas Plumbing License Law & Board Rules
- OSHA 29 CFR 1926
Fees & timeline for the Texas contractor license
- $115 TDLR application fee for electrical/HVAC
- $78 PSI exam fee per module
- $111 plumbing exam fee via TSBPE
- $300k liability insurance minimum for TDLR contractors
- City registration fees and bonds ($5k-$25k) for general contractors
Confirm fees with TDLR, TSBPE, and the city where you pull permits—municipal GC registration costs vary widely.
Texas Business & Law focus
TDLR electrical and HVAC paths include business/law coverage of licensing statutes, penalties, lien basics, payroll, and safety. Plumbers follow TSBPE's law and rules exam. Treat Texas lien notices (Property Code Chapter 53) as high-yield study—not optional reading.
- Understand TDLR electrical/HVAC statutes and administrative penalties
- Know Texas lien law (Property Code Chapter 53) and notice deadlines
- Register with the Comptroller for sales tax and franchise tax as required
- Maintain OSHA heat-stress and confined-space safety plans for Texas jobsites
Practice with our Business & Law exam hub for cross-state baseline rules.
NASCLA acceptance in Texas
Texas does not use NASCLA for state trade licensing. Electrical and HVAC credentials come from TDLR exams, plumbing from TSBPE, and general contracting from city registration—not a NASCLA statewide building exam path. Confirm the current candidate bulletin for your classification, then use timed state-specific practice instead of assuming an out-of-state NASCLA letter will transfer. Use timed practice to rehearse the modules and paperwork that still apply after any out-of-state credential review.

A focused 4-week study plan for the Texas exam
Because Contractors plan for extreme rooftop heat in Houston, expansive clay around Dallas, and desert wind in El Paso, this four-week outline targets what Texas field inspectors and your licensing board exam items actually test—not generic national prep.
- Week 1 — Map the exam. Pull your current candidate bulletin, list every reference, and confirm the modules you have to pass. Start a one-page error log. Spend extra time on: NEC 2023 and Texas amendments for electrical paths.
- Week 2 — Code book navigation. Drill open-book lookups (or memorisation drills if your module is closed-book) until you can find any answer in under 60 seconds. Anchor practice around: International Mechanical and Fuel Gas Codes for HVAC.
- Week 3 — Business & Law. TDLR electrical and HVAC paths include business/law coverage of licensing statutes, penalties, lien basics, payroll, and safety. Plumbers follow TSBPE's law and rules exam. Treat Texas lien notices (Property Code Chapter 53) as high-yield study—not optional reading. Layer in scenario-based questions on contracts, lien notice, payroll, and insurance.
- Week 4 — Full simulations. PSI delivers TDLR electrical and HVAC exams statewide; TSBPE provides in-person and computer exams for plumbers. Run two full-length timed simulations. Review every miss with a one-sentence rule statement.
FAQs - Texas contractor exam
Does Texas license general contractors?
No statewide general contractor license exists. Remodelers, framers, and many GCs operate under city registration (Austin, Dallas, San Antonio, Fort Worth, and others) with local bond and insurance rules. State licenses apply to regulated trades such as electrical, HVAC, plumbing, and irrigation.
Which trades require state exams?
Electrical and HVAC/refrigeration go through TDLR with PSI exams. Plumbing goes through the Texas State Board of Plumbing Examiners. Irrigation, fire protection, elevators, and other specialties have their own state programs. Always match your bid scope to the correct board before you schedule.
Are Texas contractor exams open book?
TDLR electrical and HVAC exams generally allow approved NEC/IMC references under PSI open-book rules, but you must follow the candidate bulletin for tabs and editions. TSBPE plumbing exams emphasize license law and board rules—do not assume every Texas trade uses the same open-book format.
What insurance is required?
TDLR contractors typically need at least $300,000 general liability insurance, and cities often add bond or insurance minimums for GC registration. Workers' compensation is optional for many private Texas employers, but project owners and municipalities may still require certificates.
Does Texas accept NASCLA?
No. Texas trade credentials are board-specific (TDLR or TSBPE), and general contracting is municipal. A NASCLA score does not replace those Texas exams or city registration requirements.
Where are Texas contractor exams offered?
PSI centers statewide deliver most TDLR electrical and HVAC exams. Plumbing candidates use TSBPE exam locations or computer-based options listed by the board. Bring two IDs, approval letters, and only the references your bulletin allows.
Do I need a contractor excise tax license in Texas?
Texas does not use a contractor excise tax license like some states. You may still need Comptroller registrations for sales tax or franchise tax depending on how you bill taxable services—confirm with the Comptroller for your entity type.
City registration vs state trade license — which do I need first?
If you perform electrical, HVAC, or plumbing work, secure the state trade credential first; cities will not let a non-licensed trade pull those permits. If you only do general remodeling without a regulated trade, start with the city GC registration where you will pull permits.
