Why General Contractors Need Insurance in Washington
General contractors get sued for everything. Unlike specialty trades, GCs run the whole project — and that means you inherit risk from every sub, every material, and every phase. If something goes wrong, you're the first name on the lawsuit.
WA holds GCs to strict standards. Under RCW 18.27, you have to register with L&I, carry a $30,000 surety bond, and show proof of liability insurance before you can legally work. L&I enforces this hard. Unregistered contractors face $5,000 fines per infraction. Homeowners can file bond claims for defective or incomplete work.
The real risks are everywhere. Your crew nicks a gas line during excavation — your GL responds to the property damage and any injuries. A sub damages a neighbor's fence — your policy covers it because you hired the sub. A finished project develops a leak six months later — your completed-operations coverage handles it.
WA's construction defect statute (RCW 64.50) gives homeowners up to six years to file claims for defective work. That long tail means your insurance has to protect you years after the job ends, not just today. Operating without the right coverage isn't risky — it's the fastest way to lose your business.

How Much Does General Contractor Insurance Cost in Washington?
Most WA general contractors pay $89-$350/month for general liability. Residential remodelers under $500K in revenue come in low. Commercial GCs running $2M+ projects pay $250-$350/month or more. Claims history is the biggest rate driver — one major claim can double your premiums for 3-5 years. Revenue, payroll, sub usage, and project type all move the number. Most carriers require $1M per occurrence / $2M aggregate. Bigger commercial owners often require $5M umbrella on top.
