2025 Rulemaking
Fee increase

L&I is considering a fee increase to cover operating expenses, electrical inspections and other program public safety activities for the agency’s Electrical Program.

A fee increase by the fiscal growth factor rate (average personal income growth over the past decade) is under consideration. The fiscal growth factor is 6.41% for fiscal year 2026. The agency filed a CR-101 Preproposal Statement of Inquiry on January 2.

The changes affect rules under:

  • WAC 296-46B-906, Inspection Fees;
  • WAC 296-46B-909, Electrical/telecommunications contractor's license, administrator certificate and examination, master electrician certificate and examination, electrician certificate and examination, copy, and miscellaneous fees; and
