Rule Development

2025 Rulemaking
Fee increase

L&I is proposing fee increases by 6.41% to cover operating expenses, electrical inspections and other program public safety activities for the agency’s Electrical Program.

The agency filed a CR-102 Proposed Rulemaking on Feb. 18. The fee increase is the maximum allowed by the state Office of Financial Management for fiscal year 2026. It is based on the average personal income growth over the past decade.

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
  • WAC 296-46B-911, Electrical testing laboratory and engineer accreditation fees.

    If adopted, the rule amendments would take effect July 1, 2025.

A public hearing on the proposed rules will take place March 25, 2025, starting at 10 a.m. at L&I headquarters, 7273 Linderson Way S.W., Tumwater, WA.
