Do you need a general contractor license in Washington?

While you technically don’t need a license, Washington state general contractors do need to register with the Department of Labor & Industries (L&I).

According to the state legislation, the term “contractor” covers three different definitions related to construction and building: 

  1. Any person or entity that, as an independent business, offers to or performs construction, repair, or improvement work on buildings or land—this includes property owners who manage more than one type of specialty contractor to complete a single job or project
  2. A building consultant acting as a general contractor
  3. Any person or entity who offers to sell their property without occupying it or using it to operate a business for more than one year since construction or improvements were completed

Essentially, registered general contractors are involved in the planning and completion of any construction projects in Washington state.
