Registration as a specialty contractor in Washington requires a $15,000 surety bond on file with the Department of Labor & Industries; the general contractor requirement is $30,000.

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.

HVAC/RFRG-Restricted is a narrower heating, cooling, and refrigeration classification covering a limited range of equipment work compared with the full HVAC/RFRG category. Businesses under it typically service and install specific equipment types rather than complete systems. A $15,000 surety bond and general liability insurance, filed with WA L&I, are required for this registration.
