How Additional Insured Status Works

Adding an additional insured extends part of your policy’s protection to another party, but only in relation to your operations or work. In practice it looks something like this:

  • You perform work for a third party
  • That party is added as an additional insured on your policy
  • A claim arises tied to your work
  • Your insurance may defend and cover both you and the additional insured

You can add a person as an additional insured in the following ways:

  • Scheduled additional insured: A specific person or organization is named in your policy. This is the most precise and commonly used method for contracts.
  • Blanket additional insured endorsement: Automatically extends additional insured status to parties that require it in a written contract. This is common for businesses that frequently work with multiple clients.
  • Primary and noncontributory endorsement: Specifies that your policy pays first before the additional insured’s own insurance. Often required in contracts.
  • Ongoing operations vs. completed operations: Coverage can apply during active work, after work is completed or both. Contracts often require clarity on this distinction.

Which Business Insurance Policies Use Additional Insureds

Additional insured status is most commonly associated with liability policies, especially where contracts require risk transfer. The policies it can apply to include the following:

General Liability Insurance
Yes (most common)
Extends coverage to third parties for claims arising from your work. Frequently required in contracts.
Commercial Auto Insurance
Sometimes
Can extend liability coverage to certain third parties, depending on policy structure and endorsement.
Professional Liability Insurance
Rarely
Typically does not allow additional insureds because coverage is tied to your professional services and errors.
Cyber Insurance
Rarely
Generally limited to the insured business due to the nature of cyber risk exposure.

When and Why You Need to Add an Additional Insured

The following situations typically require you to add an additional insured:

  • Client contracts: Clients may require it to protect themselves from liability tied to your work
  • Commercial leases: Landlords often require tenants to add them as additional insureds
  • Subcontracting work: General contractors require subcontractors to add them for risk protection
  • Vendor agreements: Businesses may require vendors to extend liability coverage

Basically, if another party could be held liable for your work, they may ask to be added as an additional insured.
