What the bond and insurance requirements mean for homeowners

A $30,000 surety bond, filed with the Department of Labor & Industries, is a condition of registration for every general contractor in Washington. This contractor's current filing shows a $30,000 bond.

The bond is a limited fund a homeowner (or subcontractor or supplier) can make a claim against, through the courts, if a registered contractor fails to meet its obligations on a job. Contractors must also keep general liability insurance on file — at least $50,000 in property damage and $200,000 in public liability coverage, or a $250,000 combined single limit — which covers damage the contractor causes, not workmanship disputes. The rows above are the bond and insurance filings L&I publishes for this registration; whether a specific filing applies to a specific project depends on its dates and terms.
