Is plumber liability insurance required by law or contracts?

In many cases, yes! 

  • State licensing boards often require proof of general liability insurance. 
  • Clients—especially commercial or institutional ones—frequently mandate coverage before permitting work. 
  • Permit or contract specifications may explicitly list insurance requirements at set limits. 

Even if not mandated, carrying liability coverage builds credibility and saves you from personal financial exposure.
