GENERAL CONTRACTING x SEATTLE x WASHINGTON

General Contracting contractors in Seattle, Washington.

Operating as a general contractor in Seattle requires strict adherence to both state-level registration and city-level building codes. The Washington State Department of Labor & Industries manages the primary contractor registration, which serves as your legal authority to perform work across the state.

Once registered, you must navigate the Seattle Department of Construction & Inspections (SDCI) for all permitting and inspection requirements. Seattle maintains unique amendments to building, energy, and mechanical codes that differ from state standards, making it essential to verify project-specific requirements through the Seattle Services Portal before beginning any site work.
