Why do plumbers in Arizona need insurance?
Plumbers face risks such as leaks, property damage, lawsuits, and workplace incidents. Arizona regulates plumbing and contracting through the Arizona Registrar of Contractors (ROC), which mandates licenses, insurance, and bonding.
Anyone performing plumbing work professionally must hold a ROC license (master, specialty, or contractor license).
A licensed plumber can perform tasks, but to run a company or hire staff, a contractor’s license (such as C-37 / L-37) is required.
Contractors must carry bonding, liability insurance, and meet other state standards.
