Additional Insured Requirements for Cleaning Contractors

Before a commercial cleaning company can start work at many locations, the client's contract or property manager will demand a certificate of insurance naming them as an "additional insured." This single requirement creates more confusion and delay in cleaning sales than almost any other contract issue. Understanding what additional insured status is, why clients want it, and how to provide it — without inadvertently over-extending your coverage — is a core competency for commercial cleaning operators.

What "Additional Insured" Means

An additional insured is a person or entity that is added to an insurance policy as a protected party — in addition to the named insured (your cleaning company). When your client is listed as an additional insured on your general liability policy, they have direct rights under your policy: they can file claims under it, your insurer will defend them in covered suits, and the policy's limits apply to claims against them arising from your work.

Clients typically want additional insured status for one reason: if someone sues them because of something your cleaning crew did — a slip-and-fall caused by your mopping, a chemical spill, property damage — they want to be able to tender that claim to your insurer rather than having to use (and deplete) their own coverage.

The Endorsement: ISO CG 20 10 and CG 20 37

Additional insured status is added to a GL policy through an endorsement — a modification to the standard policy form. Two ISO endorsements are relevant to cleaning contractors:

• ISO CG 20 10: Adds the additional insured for liability arising out of your ongoing operations. Used while work is actively being performed.
• ISO CG 20 37: Adds the additional insured for liability arising out of your completed operations — claims that surface after the work is done (e.g., a floor coating failure months after installation).

Most commercial contracts require both endorsements. Some clients and contracts specify the exact endorsement numbers — read the insurance requirements exhibit carefully before submitting your certificate.

Primary and Non-Contributory Language

Many commercial contracts include a requirement that your GL policy be "primary and non-contributory" with respect to the additional insured. This means:

• Primary: Your insurance pays before the client's own insurance
• Non-contributory: Your insurer pays the full claim without demanding the client's insurer contribute

Without this endorsement, your insurer might try to "pro-rate" a claim with the client's insurer — which the client wants to avoid. You need to verify that your policy includes a Primary and Non-Contributory endorsement (ISO CG 20 01 or equivalent) to satisfy this requirement.

Your broker can confirm whether your policy includes this language or whether you need to add it as a specific endorsement.

How to Add an Additional Insured

The process is straightforward:

1. Call or email your insurance broker/agent with the client's full legal name and business address. Most policies include "blanket additional insured" language that automatically adds any party required by contract — confirm whether your policy has this, which eliminates the need to add each client individually.

2. Request a Certificate of Liability Insurance (ACORD 25 form) with the client listed in the "Certificate Holder" and "Additional Insured" sections.

3. Confirm the endorsement is reflected: The certificate should note "Additional Insured per ISO CG 20 10/20 37" (or your policy's equivalent endorsement) in the Description of Operations section.

4. Deliver the certificate before work begins. Some clients require the certificate to be sent directly from your broker (not from you) to prevent alterations.

5. Store a copy in your contract file along with the certificate sent to the client.

What Additional Insured Status Does NOT Give Your Client

Additional insured status has limits that your clients may not understand:

• The policy still only applies to claims arising from your operations — the client cannot use your policy for claims arising from their own negligence unrelated to your work
• Most modern CG 20 10 endorsements (2004+ versions) limit additional insured coverage to vicarious liability — liability the client incurs because of your actions, not their own direct negligence
• The client's additional insured rights don't exceed the policy limits; if you have a $1M GL policy, the maximum available to the additional insured (and you combined) is $1M
• Policy exclusions apply equally to the additional insured — if your policy excludes pollution or mold, the client doesn't get that coverage either

Blanket Additional Insured Policies

Rather than adding each client individually, most commercial GL policies for cleaning businesses include a blanket additional insured endorsement — which automatically extends additional insured status to any party that you're required by written contract to add. This is the most efficient approach for cleaning companies with multiple commercial accounts:

• No individual processing per client
• Coverage automatically triggers when a written contract requires it
• Still need to issue certificates for each client (the endorsement is in your policy; the certificate is evidence of it)

Confirm with your broker whether your policy has a blanket AI endorsement before assuming each client must be manually added.
