Washington Electrician Legislation, Codes, and Guidelines
Washington State Building Codes and Legislation for Electricians
In Washington State, the regulation of electricians and electrical installations is primarily governed by state statutes and administrative codes, which adopt and adapt national standards. The state generally follows the National Electrical Code (NEC), with specific state amendments.
- Adopted Codes: Washington State has adopted the 2023 Washington Cities Electrical Code, which is based on the 2017 National Electrical Code (NFPA 70). However, the state is in the process of reviewing and potentially adopting amendments based on the 2026 National Electrical Code (NEC). The Revised Code of Washington (RCW) Chapter 19.28 and Washington Administrative Code (WAC) Chapter 296-46B outline the specific electrical safety standards, administration, and installation requirements.
- Primary State Board/Agency: The Washington State Department of Labor & Industries (L&I) is the primary state agency responsible for overseeing electrical safety and licensing. The Electrical Board, appointed by the governor, advises the director of Labor & Industries on matters related to electrical installations, inspection procedures, and code adoption.
