Subcontractors are commonly required to carry their own insurance when working on construction projects. These requirements help protect both the subcontractor and the hiring contractor from financial risk if accidents, injuries, or property damage occur during the project.
This guide explains the types of insurance subcontractors typically need, why contractors require proof of coverage, and how insurance responsibilities are usually structured on construction projects.

Additional insured endorsements are commonly verified through a certificate of insurance (COI).
Before allowing subcontractors to begin work, contractors typically request documentation confirming active coverage.
This documentation may include:
