In Washington, there is no broad “handyman” licensing exemption based on a dollar threshold—if you perform construction-related work for compensation, you generally must be registered as a contractor with WA Labor & Industries (L&I). Even with contractor registration, specialty trades like electrical (and many plumbing/HVAC activities) require separate state credentials, and most jobs still require local permits in Island County/your city.
