What did Texas decide about the 2026 National Electrical Code?
The Texas Commission of Licensing and Regulation adopted the 2026 National Electrical Code (NEC) as the state electrical code. TDLR, the Texas Department of Licensing and Regulation, posted the notice on September 1, 2026. The rule has an effective date of September 1, 2026.
This is TDLR’s wording: “The adopted amendments adopt the 2026 National Electrical Code as the state electrical code, with a limited exception pertaining to ground-fault circuit interrupter requirements for certain outdoor outlets.” The rule is an amendment to 16 Texas Administrative Code, Chapter 73, section 73.100, for the Electricians program. The notice says the adoption justification ran in the August 28, 2026, issue of the Texas Register.

What does that mean for a homeowner?
For most homeowners, the main effect is on new electrical work, which licensed electricians will build to the adopted edition. TDLR’s notice does not list specific changes for homeowners, and this post does not guess at them. The NEC is a large book, and its changes are best explained by the electrician who will do your job.
You do not need to read the code. You do need a licensed person to do the work. TDLR states that anyone doing non-exempt electrical work in Texas “must be licensed and perform that work through a licensed electrical contractor.” Our guide on how to hire a licensed electrician in Texas explains how to check a license.
Will my existing wiring be out of code?
The TDLR notice does not say that existing wiring must change, and this post makes no such claim. A home wired under an older code is not a problem by that fact alone. If you are unsure about the safety of older wiring, ask a licensed electrician for an inspection. Our post on electrical checks before you buy or sell covers that.
What is the GFCI exception about?
TDLR says only that the exception concerns “ground-fault circuit interrupter requirements for certain outdoor outlets.” It gives no further detail in the notice. A GFCI is a device that shuts off power quickly when current leaks to ground, to reduce shock risk. Ask your electrician how the exception applies to an outdoor project, such as a patio, a hot tub, or a pool area. See our post on hot tub and pool electrical safety.
Why might my city list a different edition?
Cities adopt and update codes on their own schedules, so a city page can show an older edition. Argyle’s Current Codes page, as of December 1, 2024, lists the 2020 NEC. That date is before the 2026 state rule.
When you read a city page, note the date. Write “the city’s page lists” an edition, not “the city uses” it. Then ask the city building office or your electrician which rules apply to your permit. Our permit posts for Southlake, Keller, and Grapevine show what each city asks for.
What should I do if I plan a project?
Follow these steps:
- Write down what you want done and where.
- Ask a licensed electrician to review it and say which code rules apply.
- Ask whether your city requires an electrical permit and an inspection.
- Get a written quote before work starts.
- Keep the permit record and the electrician’s paperwork.
Do not do wiring work yourself. Anything inside a panel, outlet box, or fixture is work for a licensed electrician. See code compliance for what the term covers.
Where can I read the official notice?
TDLR posted its notice, “Commission Adopts Rules,” on its website under news and rulemaking for the Electricians program. The notice is short. It names the rule, the code edition, the exception, and the effective date. The full code book is published by NFPA, and it is written for trained electricians, not for homeowners.
The notice also says the updated rule chapter will appear in the Texas Administrative Code on its effective date. For your project, you rarely need to read either text. A licensed electrician reads the rules for you and builds to them. What you need is a clear scope, a written quote, and the permit paperwork if your city asks for it.

Frequently asked questions
When does the 2026 NEC take effect in Texas?
TDLR's notice says the updated rule chapter is available in the Texas Administrative Code upon its effective date of September 1, 2026. The change is an amendment to 16 TAC Chapter 73, section 73.100, for the Electricians program. The notice also names one limited exception for certain outdoor outlets.
Do I have to rewire my house to meet the 2026 NEC?
The TDLR notice does not say that, and this post does not claim it. A code edition mainly guides new work and repairs that the code covers. If you plan a project, ask a licensed electrician which rules apply to it and whether your city requires a permit.
Which code does my city use?
It depends on the city, and city pages can lag behind the state. For example, Argyle's Current Codes page, as of December 1, 2024, lists the 2020 NEC. Check your city's page or call its building office, and ask your electrician what applies to your project.
