Summary
Operating as a concrete contractor in Mount Vernon, Washington requires obtaining a state specialty contractor license through Washington L&I, which involves passing an exam and meeting experience requirements. You'll need to maintain general liability and workers' compensation insurance, post a contractor bond, and register your business with the city if working within Mount Vernon limits.
