Short answer: The insurance required for contractors depends on the type of work performed, where the work takes place, and the terms of the contract. In practice, most contractors are required to carry at least general liability insurance, and many also need workers’ compensation, commercial auto, or professional liability coverage.
This guide explains the most commonly required contractor insurance policies, when they are required by law versus by contract, and what happens if requirements are not met.
There is no single insurance policy that applies to every contractor.
Insurance requirements are typically driven by one or more of the following:
As a result, two contractors in the same city may have very different insurance obligations.
General liability insurance is the most commonly required policy for contractors.
It is frequently required:
General liability insurance covers third-party bodily injury, property damage, and certain completed operations claims. For many contractors, this is the minimum coverage needed to operate.
Workers’ compensation insurance is typically required when a contractor has employees.
In most states:
Workers’ compensation covers medical expenses and lost wages for employees injured on the job.
Even when not legally required, many contractors carry workers’ compensation to meet contract requirements or reduce liability exposure.
Commercial auto insurance is required when vehicles are used for business purposes.
This applies to:
Personal auto policies often exclude business use, which can leave contractors uninsured in the event of an accident.
Professional liability insurance, also called E&O insurance, is required in certain situations.
It is most commonly needed when contractors:
Professional liability insurance covers claims related to errors, omissions, or professional advice — not physical damage or injuries.
This coverage is often required by contracts rather than by law.
Depending on the project or client, contractors may also be required to carry:

Contractors who fail to meet required insurance standards may face:
Insurance requirements are often enforced before work begins, but problems can also surface after a claim occurs.
Most contractors determine required insurance by reviewing:
Because coverage details and limits vary, contractors often compare policies to ensure requirements are met without unnecessary coverage gaps.
