What is a Certificate of Insurance (COI) and Why Do General Contractors Demand It?

The Essential Document for Winning Commercial Contracts in SC

A Certificate of Insurance (COI) is a standardized document issued by your insurance broker verifying active policy types, coverage limits (typically $1M / $2M), and policy term dates.

Why do General Contractors and Property Managers require a COI?

GCs mandate COIs prior to site access to ensure that if accidental property damage or injuries occur on the job, your insurance policy covers the loss rather than theirs.

Key COI Terminology:

• Certificate Holder: The company requesting proof of coverage.
• Additional Insured: Endorsement protecting the project owner under your liability policy.
• Waiver of Subrogation: Agreement preventing your insurer from seeking reimbursement from the holder.
