Many people underestimate the importance of liability insurance, thinking “It will never happen to me.” Be sure to talk with your agent about appropriate liability coverages for the type of work you do.
Since there is always a possibility that someone will file a lawsuit against you claiming to have been harmed by your work, you will almost certainly need liability insurance.
You may want to require your subcontractors to have Owners and Contractors Protective Liability Coverage (OCP). This coverage protects either a property/businessowner or a general contractor from possible liability arising from the negligent acts of an independent contractor or subcontractor hired to perform work on behalf of the insured. The actual purchaser of the policy is the independent contractor or subcontractor, but the protection is for the benefit of the property/businessowner or general contractor for whom the work is being done.
