Texas NEC Code Adoption — 2026 NEC Transition and Local Code Splits

Texas is transitioning from the 2023 National Electrical Code to the 2026 NEC on September 1, 2026. That change ripples through licensing exams, contractor operations, and municipal code enforcement — and it does not land evenly across the state.

The State Adoption Timeline

TDLR's Electrical Safety and Licensing Advisory Board recommended adoption of the 2026 NEC, with the effective date set for September 1, 2026. This is the edition that governs the minimum electrical standards for all state-regulated work and all licensing examinations administered through PSI.

Before September 1, 2026, the 2023 NEC remains the operative code for state-level licensing and compliance. After that date, the 2026 NEC applies.

For exam candidates, this means your PSI exam is based on whichever NEC edition is in effect on your test date. If you are sitting for the journeyman or master exam before September 1, bring a 2023 NEC codebook. After September 1, you need the 2026 edition. The exam is open-book — your codebook is your primary reference — so having the wrong edition is a serious problem.

What Changes in the 2026 NEC

The 2026 NEC introduces updates across several areas relevant to Texas electricians, though the specific exam impact depends on which provisions TDLR's exam committee emphasizes. Key areas that typically draw exam questions include:

• GFCI protection requirements (Article 210)
• Arc-fault circuit interrupter provisions
• Emergency system requirements
• Grounding and bonding updates
• Renewable energy and energy storage system provisions

Texas has maintained a state-level exception for GFCI protection on outdoor HVAC units under NEC Section 210.8(F). Verify whether this exception carries forward into the 2026 adoption before relying on it for installations.

The Municipal Code Split

Here is where it gets complicated. While the state adopts the 2026 NEC statewide, individual municipalities are not required to follow the same edition on the same timeline.

The most significant current split:

• State standard: 2023 NEC (transitioning to 2026 NEC on September 1, 2026)
• Dallas: Enforces the 2020 NEC with Dallas-specific amendments — not the state-adopted edition
• Houston, Austin, San Antonio, El Paso: Follow the state-adopted NEC cycle

Dallas's decision to remain on the 2020 NEC with local amendments creates a practical compliance issue for contractors who work in the Dallas-Fort Worth metropolitan area. A contractor pulling permits in Fort Worth operates under the state-adopted 2023 NEC (and will transition to 2026), while the same contractor crossing into Dallas must comply with the 2020 NEC plus Dallas amendments.

The differences are not always obvious. Provisions that changed between the 2020 and 2023 editions — and again between 2023 and 2026 — may apply in one city and not the other. Always verify the locally adopted code edition with the municipal building inspection office before starting work.

Impact on Continuing Education

TDLR requires 4 hours of annual continuing education for individual license holders; apprentices may instead renew by proving active enrollment in a department-registered apprenticeship program. For the CE option, 1.5 hours are specifically devoted to the NEC. CE providers must be TDLR-approved. For a course taken near the transition, confirm with the provider or TDLR which NEC edition and renewal requirements apply.

The transition year often prompts providers to offer bridge courses covering the differences between editions. These can be valuable for contractors who need to understand what changed and how it affects their current projects.

How to Prepare

If you are approaching the exam date near the September 1 cutoff, confirm with PSI which NEC edition applies to your scheduled test. Purchasing the wrong codebook is an expensive mistake — soft-bound NEC editions typically cost $100–$150 with tabs.

For working contractors, review any active projects that will span the September 1 date and confirm with the local authority having jurisdiction which NEC edition applies to the permit and inspections.

The Texas Electrician License Guide tracks the code transition alongside exam logistics and municipal compliance requirements, so you know exactly which edition applies in every context.
