In Washington, a "handyman" generally must register as a Washington contractor if they advertise or perform construction/repair/improvement for the public—there is no broad handyman dollar-threshold exemption from contractor registration. Even for small jobs, specialty trades (electrical/plumbing/HVAC/refrigeration) require separate state credentials and permits may still be required by the local building department in Thurston County.
