How to verify a Contractor's License in Washington State

Gus Koedding • January 23, 2025

To check a contractor's license in Washington State, you can use the Washington State Department of Labor & Industries (L&I) website. Here's how you can do it:

Steps to Verify a Contractor's License:

  1. Visit the L&I Website:
  1. Enter the Contractor's Information:
  • You can search using:
  • The contractor’s name.
  • Their business name.
  • Their contractor license number.
  • Enter the details in the search box and click Search.
  1. Review the Results:
  • Look for:
  • Active License Status: Ensures the contractor is currently licensed.
  • Bond and Insurance Information: Verify they have the required bond and liability insurance.
  • Registration Details: Confirms they are registered with the state.
  • Violation History: Check for any past infractions or unresolved claims.
  1. Cross-Check Additional Details (Optional):
  • Confirm the contractor’s name and business information match the details on the website.
  • Check reviews and testimonials for more insight into their work.

What to Look for in a Licensed Contractor:

  • Active Registration: The license should be current.
  • Bonding and Insurance: Verify that they have the required general liability insurance and a bond to protect you in case of damages or non-compliance.
  • No Red Flags: Look for a clean record with no unresolved violations or lawsuits.

Why It’s Important

  • Hiring a licensed contractor ensures they are compliant with Washington state laws and regulations.
  • Licensed contractors are bonded and insured, providing you with financial protection in case of damages or unfinished work.
