NEC 2026 now in force in four states, with major changes for low-voltage cabling installers

As of October 14, 2026, four states — Massachusetts, Texas, Arkansas, and Oregon — enforce the 2026 edition of the National Electrical Code. Oregon went live October 1. Washington has proposed an effective date of December 31, 2026.

The 2026 NEC makes the most significant structural change to the communications wiring chapter in over 80 years. Chapter 8, which historically governed interior communications and structured cabling independently of the rest of the code, has been reduced to outdoor and building-entry work only. Interior low-voltage and communications cabling requirements have moved into a new set of articles — 720 through 750 — and are now subject to the general wiring requirements of Chapters 1 through 7. A new Article 750 consolidates grounding and bonding requirements for limited-energy systems, meaning structured cabling racks, shielded patch panels, and surge protection devices must bond directly back to the building's primary grounding electrode system. The NFPA's own adoption table was noted in October as being out of date for several states, so confirming local adoption status directly with the relevant authority is advisable.

For facilities managers and IT directors in affected states, this is a good time to verify that any active or upcoming cabling projects reference the correct code edition. Contractors, inspectors, and permitting offices in those jurisdictions are now working under the 2026 rules. Organizations with projects spanning multiple states may encounter both 2023 and 2026 article references on work running concurrently.
