How NEC Adoption Works

The National Electrical Code (NEC), also known as NFPA 70, is a regional standard for the safe installation of electrical wiring and equipment in the United States. While the National Fire Protection Association (NFPA) updates the code every three years (e.g., 2017, 2020, 2023), adoption is handled at the state or local level.

Statewide Adoption

Most states have a central Building Code Commission that mandates a specific version of the NEC for all jurisdictions within the state.

Local Control

States like Arizona, Illinois, and Missouri allow local counties or cities to decide which NEC version to adopt and enforce.

Amendment Variations

States often adopt the NEC with specific "amendments" or exceptions to suit local environmental or industrial needs.

Cycle Skipping

Due to legislative delays or administrative slow-down, some states may skip an entire 3-year cycle before updating.
