Insurance: General liability of $200,000 public liability plus $50,000 property damage, or $250,000 combined single limit. A certificate of insurance must be filed each year before the policy expires. Bond is a $6,000 Washington continuous plumbing contractor surety bond or an assigned savings account (up to three times that, maximum $18,000, with prior judgments; WAC 296-400A-012). A separate bond is required for each certification, registration or license held.

Notes

Plumbing contractor license is separate from the RCW 18.27 contractor registration. Fee is $148.10 for 2 years and reinstatement is $74.00 under WAC 296-400A-045 effective 7/1/2026 (the L&I page may still show the earlier $139.10 and $69.50). A designated plumber with a journey level or specialty certificate must be assigned; initial identification or change of designated plumber is $53.20.

Notes

Washington has no separate state roofing license. Roofing is a specialty contractor classification under WAC 296-200A-016, so roofers register with L&I as specialty contractors with a $15,000 bond (a contractor registered as a general contractor posts $30,000). Fee is $150.20 for 2 years (eff. 7/1/2026).
