Texas has no single statewide electrical code—cities adopt independently and low voltage is exempt from state licensing. Here's how to navigate NEC 2026 across Texas metros.

NEC 2026 Impact for Texas Low Voltage Contractors: City-by-City Adoption Guide

Texas doesn't enforce a single statewide electrical code like most states. Major cities adopt independently, TDLR exempts most low voltage work from electrician licensing, and alarm/security contractors answer to DPS instead. Here's how to navigate NEC 2026 in the Lone Star State.

Quick Answer

Texas has a minimum statewide code (NEC 2023 as of September 2023 via TDLR), but local jurisdictions can adopt their own versions with amendments. Low voltage work on Class 2/3 circuits, fire alarm, optical fiber, and communications is exempt from state electrician licensing—though cities can override this. Alarm and security work requires DPS Private Security Bureau licensing, not TDLR. NEC 2026 will roll out city-by-city, with major metros like Dallas evaluating amendments in Spring 2026.

The Texas Difference: Why It's Complicated

Texas operates unlike any other major state for electrical code enforcement:

  • TDLR Sets Minimum: Texas Department of Licensing and Regulation establishes a statewide minimum (currently NEC 2023)
  • Local Control: Cities and counties can adopt stricter codes or different versions
  • Low Voltage Exemptions: Most low voltage work is exempt from electrician licensing at the state level
  • Municipal Override: Cities can require licensing that the state doesn't
  • Dual Authority: TDLR handles electricians; DPS handles alarm/security contractors

Note: NEC 2025 doesn't exist—the Dallas area Electrical Advisory Board is reviewing NEC 2026, which publishes in late 2025. Spring 2026 amendments will likely be for NEC 2026 adoption.

TDLR Low Voltage Exemptions

Under Texas Occupations Code Section 1305.003(a)(12), the following work is exempt from state electrician licensing:

  • Class 1, Class 2, and Class 3 remote control, signaling, or power-limited circuits
  • Fire alarm circuits
  • Optical fiber cables
  • Communications circuits

This means at the state level, you don't need a TDLR electrician license to:

  • Install structured cabling
  • Run fire alarm systems
  • Set up security camera systems
  • Install access control
  • Pull fiber optic cable

The Municipal Override

Here's the catch: Section 1305.201 of the Texas Electrical Safety and Licensing Act allows municipalities to override these exemptions and impose their own requirements.

This creates a patchwork where:

  • One city might require permits and licensed electricians for low voltage work
  • A neighboring city might not require anything
  • Unincorporated county areas might have no enforcement at all

Always verify with the local jurisdiction before starting work.

DPS Private Security Bureau: Alarm and Security Licensing

While TDLR exempts low voltage from electrician licensing, alarm and security work has its own licensing authority: the Texas Department of Public Safety Private Security Bureau (DPS PSB).

Who Needs DPS PSB Licensing?

Work TypeLicense RequiredAuthority
Alarm system installationAlarm Systems Installer (Individual)DPS PSB
Alarm monitoringAlarm Systems MonitorDPS PSB
Alarm company operationAlarm Systems CompanyDPS PSB
Access control installationElectronic Access Control Device InstallerDPS PSB
Access control companyElectronic Access Control Device CompanyDPS PSB
CCTV only (non-alarm)Generally exemptN/A
Structured cabling onlyGenerally exemptN/A

Alarm Installer Training Requirements

DPS PSB requires:

  • First 12 Months: Complete Alarm Level I training (16 hours classroom or approved online), including 2 hours on NEC as it applies to low voltage
  • Continuing Education: 8 hours every 24 months in alarm-related fields, including 1 hour on NEC for low voltage

Note that DPS PSB training explicitly references the NEC—so NEC 2026 changes to limited-energy articles will eventually affect alarm installer training content.

Access Control vs. Alarm

Important distinction: A person licensed as an electronic access control device installer may NOT install alarm systems unless they also hold an alarm systems installer license. These are separate certifications even though the work often overlaps.

Major Texas Cities: NEC 2026 Outlook

Houston

The Houston Permitting Center has been reviewing electrical plans to NEC 2023 since the state mandate. Houston typically follows the state minimum with minimal local amendments.

NEC 2026 Outlook: Likely to adopt when TDLR updates the state minimum. Watch for announcement from the Houston Permitting Center.

Dallas-Fort Worth (NCTCOG Region)

The North Central Texas Council of Governments (NCTCOG) coordinates electrical code adoption for the Dallas-Fort Worth metroplex through its Regional Codes Coordinating Committee.

Current status:

  • NEC 2023 amendments approved August 2023
  • Electrical Advisory Board currently reviewing NEC 2026
  • Recommendations expected Spring 2026

NEC 2026 Outlook: The NCTCOG region is actively preparing for NEC 2026 adoption with local amendments. Expect adoption in 2026 with regional amendments.

San Antonio

San Antonio Development Services enforces electrical codes with local amendments. The city maintains its own amendment process separate from NCTCOG.

NEC 2026 Outlook: Will likely follow state adoption timeline, possibly with local amendments. Check with Development Services for specific timeline.

Austin

Austin has historically been progressive on building codes, often adopting amendments for energy efficiency and sustainability beyond state minimums.

NEC 2026 Outlook: Austin may adopt NEC 2026 relatively quickly once available, potentially with local amendments related to energy and electrification goals.

Unincorporated Areas

Many areas of Texas outside city limits have limited or no code enforcement. The state minimum applies where the state has jurisdiction, but practical enforcement varies widely.

How NEC 2026 Changes Affect Texas

Chapter 7 Reorganization

NEC 2026's new limited-energy framework affects all low voltage work:

  • Article 720: General requirements for limited-energy systems
  • Articles 721-723: Class 2/3 power sources, cables, installation
  • Article 726: Class 4 Fault-Managed Power (already in NEC 2023)
  • Article 742: Communications and overvoltage protection
  • Article 750: Unified grounding requirements

For Texas contractors working on exempted low voltage circuits, these articles define the technical requirements even if state licensing doesn't apply.

Chapter 8 Independence Ending

NEC 2026 removes Chapter 8's historic independence. Communications interior wiring now follows Chapter 7 like other limited-energy systems.

Impact for Texas: The work doesn't change, but code references do. When cities adopt NEC 2026, structured cabling work will reference Article 720, 742, and 750 instead of Article 800 for interior installations.

Fire Alarm (Article 760)

Fire alarm systems remain in Article 760 but now integrate with the Article 720 general requirements.

For Texas DPS PSB licensees: Fire alarm training will eventually reference the new article structure. The core technical requirements remain similar.

Key Recommendations for Texas Contractors

  1. Verify Local Requirements: State exemptions don't override municipal requirements. Check each jurisdiction before bidding.
  2. Maintain DPS PSB Licenses: If you do alarm or access control, keep DPS Private Security Bureau licenses current.
  3. Track City Adoptions: Houston, Dallas (NCTCOG), Austin, and San Antonio may adopt NEC 2026 at different times with different amendments.
  4. Learn NEC 2026 Structure: Even without licensing requirements, understanding Articles 720-750 helps with inspections and specifications.
  5. Separate Alarm from Access Control: In Texas, these are separate DPS PSB license categories. Don't assume one covers both.
  6. Document Everything: In a patchwork enforcement environment, documentation protects you.
