Workers' Comp Insurance for Plumbing Businesses in Wyoming
Plumbing contractors (NCCI 5183) typically face moderate workers' comp rates — much lower than roofing or framing, but higher than office-only operations. Lifting injuries and slip-and-fall claims drive most losses. Service plumbers, drain cleaning, and new-construction plumbing all use the same primary code but may have different sub-classifications in Wyoming. The Wyoming workers' compensation market is governed by WSD (state fund) — a monopolistic state fund (no private market), and the average rate statewide is approximately $1.27 per $100 of payroll.
Wyoming requirements for plumbing businesses
When required: All employers in 'extra-hazardous' industries must obtain coverage through Wyoming Workers' Safety & Compensation Division — monopolistic for those industries.
Sole proprietors: Optional for sole proprietors.
Owner / officer exclusion: Officers may be excluded.
⚠️ Wyoming is a monopolistic state
All Wyoming workers' comp coverage must be purchased through the state fund (WSD (state fund)). Private workers' comp insurance is not available in Wyoming, but we can help with employer's liability ("stop-gap") coverage that complements the state fund.

Why plumbing workers' comp is tricky in Wyoming
Plumbers who do their own gas line work or HVAC ductwork may be misclassified — these activities have separate codes. Apprentices, clerical staff, and outside salespeople should be coded separately to keep your effective rate low.
