EV Charger Permits in Texas: NEC Rules, TDLR Licensing and City Requirements
How the NEC, TDLR licensing rules and city permits apply to a home EV charger installation in Texas, including the homeowner exemption.
The short version
In Texas, installing a Level 2 EV charger is electrical work regulated by the state. It generally has to be done by licensed electricians working for a business that holds a Texas Electrical Contractor license from the Texas Department of Licensing and Regulation (TDLR). The work has to meet the National Electrical Code (NEC), and most cities also require a local permit and inspection. The rules differ in some details from city to city, so this guide explains the statewide framework and then how a few large cities handle it.
Which electrical code applies in Texas
Texas adopts the NFPA's National Electrical Code (NFPA 70) by rule. The 2023 NEC took effect statewide on September 1, 2023, according to the TDLR compliance guide. In July 2026 the Texas Commission of Licensing and Regulation adopted the 2026 NEC as the state electrical code, effective September 1, 2026, with a limited Texas exception on GFCI requirements for certain outdoor outlets, as described in TDLR's rule adoption notice.
Cities also adopt electrical codes through local ordinances, sometimes with local amendments and on their own schedules. If your project straddles the change, ask your electrician which edition your city's inspector is enforcing.
NEC requirements that matter for an EV charger
Article 625 of the NEC covers electric vehicle charging equipment. Several points come up on almost every home install:
- Continuous load. EV charging is treated as a continuous load, so the branch circuit and breaker must be rated at no less than 125 percent of the charger's maximum load. A 48-amp charger needs at least a 60-amp circuit.
- A dedicated circuit. Charging equipment is generally supplied by its own branch circuit rather than sharing one with other loads, unless an approved energy management system controls the load.
- GFCI protection for receptacles. Receptacles installed for EV charging must have ground-fault circuit-interrupter protection (section 625.54 in the 2023 edition). This is why a plug-in charger on a NEMA 14-50 outlet usually needs a GFCI breaker. Hardwired chargers typically have built-in protection.
- Load calculation. Adding a large continuous load can push a home past its service capacity. Article 220 provides the methods electricians use to check this. The NEC also recognizes energy management systems that limit charging current so a charger can fit within an existing service.
- Listed equipment and correct location. The charger must be listed and installed according to its instructions, with outdoor-rated equipment used outdoors.
What TDLR requires
Texas Occupations Code Chapter 1305 and TDLR's rules at 16 TAC Chapter 73 govern electricians. The key points for a homeowner or business owner:
- Licensed people do the work. Electrical work, which the law defines broadly to include installing, maintaining or extending a wiring system, must be performed by licensed electricians, with apprentices working under supervision.
- A licensed contractor offers the work. A business that contracts to do electrical work needs an Electrical Contractor license. To get one, the business must be a Texas master electrician or employ one, and it must carry general liability insurance of at least $300,000 per occurrence, $600,000 aggregate, and $300,000 aggregate for products and completed operations under 16 TAC Section 73.40.
- Visible license numbers. TDLR requires electrical contractors to show their license number on their vehicles with the prefix TECL.
The homeowner exemption, and its limits
Section 1305.003(a)(6) of the Occupations Code exempts work "not specifically regulated by a municipal ordinance" that is performed in or on a dwelling by a person who owns and lives in that dwelling. Two cautions apply:
- The exemption covers the owner doing the work personally. It does not cover hiring an unlicensed handyman, and it does not apply to rental property or a business.
- If your city regulates the work by ordinance, the city's rules control. Many cities require a homeowner's permit, an inspection, and sometimes a test.
City permits: a few examples
- Houston. The Houston Permitting Center says that registered electrical contractors installing an EV charging outlet must apply for an electrical permit and that electrical permits are issued only to registered master electricians. Plans are required for Level 3 (DC fast) outlets. See the EV charging outlet permit page.
- Dallas. A homeowner may act as their own contractor on their homestead with a homeowner's permit, but for electrical work the city lists electrical repairs "after passing an approved City of Dallas oral or written exam." The homeowner must sign an affidavit, witnessed by an electrical inspector, stating that no one else will be paid to do any part of the work. See the Dallas homeowner exemption form.
- Austin. Austin Energy's home charger rebate requires a City of Austin electrical permit and inspection for every hardwired charging station, installed by a licensed electrician.
- San Antonio and other cities. Check with the city's development services or building inspection department. Fees, processing times and homeowner options vary.
Practical takeaways
- Assume a permit is needed for a new 240-volt circuit until your city says otherwise.
- Have the contractor pull the permit in their company's name, and keep the final inspection record. Rebates, insurers and future buyers may ask for it.
- Confirm the contractor's license on the TDLR license search before any work begins.
