How Much Does Contractor Insurance Cost?

A contractor's insurance cost depends mostly on your trade, your size (payroll and revenue), and which coverages your contracts require. Here's what goes into the number and how to keep it reasonable.

Short answer: Most contractors are priced on trade risk + revenue/payroll. A low-hazard trade like handyman or painting prices far below a high-hazard trade like roofing or excavation. Your total also depends on whether you need just general liability or a full program (GL + workers' comp + auto + tools).

Typical 2026 premium ranges

Industry benchmark data (MoneyGeek, 2026) puts general liability for a small 1–4 person contracting business at about $4,000 per year on average, with a wide spread by trade: painters average around $2,500/yr, handyman services about $2,600/yr, plumbers and electricians roughly $4,400–$4,600/yr, general contractors near $4,900/yr, and roofers around $7,800/yr. California pricing often runs above these national figures, and workers’ comp is priced separately per $100 of payroll by class code. Your real number comes from a quote — these ranges tell you the ballpark.

What determines your premium

  • Trade / class — the single biggest factor; high-hazard trades (roofing, excavation, framing) cost more than finish trades.
  • Revenue & payroll — GL often rates on gross receipts or payroll; bigger operations pay more.
  • Coverages required — GL only, or GL + WC + commercial auto + tools/equipment.
  • Limits & contract terms — additional insured, primary & noncontributory, and waivers can affect pricing.
  • Experience & claims — years in business and loss history.

How to lower it

  • Classify your operations accurately — don't pay a higher-hazard rate than your work warrants.
  • Transfer risk to subs correctly (collect their COIs) so they aren't added to your audit.
  • Bundle GL + auto + tools where it earns credits; carry the limits your contracts actually require — no more, no less.
  • Shop across carriers by trade — appetite and price vary a lot.

What's the biggest factor in contractor insurance cost?

Your trade. High-hazard trades like roofing and excavation price well above finish trades like painting or flooring, because of claim frequency and severity.

It depends on your payroll and trade. For labor-heavy high-hazard trades, workers' comp is often the larger line; for others, GL and auto dominate.
