Do you need a state license in Washington?
Washington licenses some general contractor work at the state level and leaves the rest alone. Which side of that line a job falls on decides whether you need the state license.
A single job under $500 for labor and materials that is casual, minor or inconsequential is exempt, but not if it is part of a larger job, split up to avoid registering, or if you advertise as a contractor.
Plumbing, electrical, elevator, boiler, manufactured home and asbestos work carry their own state licenses on top of contractor registration.
Washington license types for general contractor work
