Checks for Electricians

  • Electrical work is regulated under RCW 19.28 by the L&I electrical program, separately from general registration. Check the business's electrical contractor license and each worker's electrician certificate.
  • Most electrical work needs a permit and inspection from L&I or a city with its own program.
  • Electrical contractor records usually show a bond but no construction insurance record; that is expected.
