Additional Insured Endorsements Explained
Landlords, general contractors and clients often ask to be added to your policy as an additional insured. Here is what that request means, how the endorsement works and what to gather before you say yes.
What additional insured status means
Your policy is written for your business, the named insured on the declarations page. An additional insured is another person or company that gains some protection under your policy because you asked for it, usually to meet a lease or contract. IRMI’s glossary describes it as a party added at the policyholder’s request, typically to honor a close business relationship or a contractual promise.
The protection is narrower than your own. Most additional insured endorsements reach the other party only for claims connected to your work, your premises or your products, and only within the limits you carry. The endorsement wording controls the details, so the same phrase on two different policies can mean quite different things.
Who asks for it, and why
The request almost always travels with a contract. A landlord wants to be protected if a customer is hurt inside the space you lease. A general contractor wants your policy to respond first when your crew’s work causes an injury on the jobsite. Property managers, event venues, equipment lessors, public agencies and larger clients all use the same tool for the same reason: they want your coverage, not theirs, to absorb the claims your business creates.
Read the request in context. The guide to commercial lease insurance requirements covers what landlords typically ask for, and insurance requirements in client contracts walks through service agreements and subcontracts. Knowing which document created the request tells you exactly whose name must appear and for which work.
Blanket and scheduled endorsements
There are two common ways to add someone. A scheduled endorsement lists the other party by name, which works well for a single landlord or one large client. A blanket endorsement extends additional insured status automatically to anyone you have agreed in a written contract to add, which suits contractors and service businesses that sign new agreements every month.
Blanket wording usually carries conditions. Many forms require the written contract to be signed before the work begins or before the injury happens, so a handshake deal or a contract signed after the fact can fall outside it. Ask the agent or insurer to compare the endorsement’s conditions with how you actually sign and start work.
Ongoing work versus finished work
Contractors and installers often see two separate requests. Ongoing operations coverage protects the other party while you are actively working on the project. Completed operations coverage extends that protection after the job is done, when a problem with your finished work causes an injury or damage months later.
General contractors and developers frequently ask for both, sometimes for a stated period after the project ends. Read the contract for that period and bring it to the quote, because a policy that addresses only ongoing work leaves the second half of the request unanswered. The contractor insurance checklist lists the other paperwork that tends to arrive with these jobs.
An additional insured is more than a certificate holder
A certificate holder simply receives a copy of the certificate of insurance as evidence that your coverage exists. California Insurance Code section 384 requires certificates to state that they do not amend, extend or alter the coverage of the policies they describe. Listing a landlord in the holder box therefore does nothing on its own to give them protection under your policy.
Additional insured status comes from an endorsement attached to the policy itself. When a client asks for both, the certificate shows the endorsement exists and the endorsement does the work. Some clients ask for a copy of the endorsement page along with the certificate, so request both from the issuer at the same time.
Wording that usually comes along
An additional insured request is rarely alone. Contracts often add that your coverage be primary and noncontributory, meaning your policy responds before theirs and does not ask theirs to share, and that your insurer give up its right to recover from them through a waiver of subrogation. Some also ask for notice before cancellation.
The request can reach beyond general liability. Leases and contracts sometimes ask for additional insured status on commercial auto and on a commercial umbrella too. Ask how each of your policies handles the request, since every line has its own endorsement and its own conditions.
Handling a request step by step
- Get the other party’s exact legal name and address as the contract states them.
- Copy the full insurance section, including any requests for primary wording, waivers or completed operations.
- Note when the work or lease begins and how long the contract runs.
- Ask whether your policy already carries a blanket endorsement or needs a scheduled one added.
- Request the certificate and the endorsement page together once the change is in place.
- Keep the contract, the endorsement and the certificate in one job file.

A few useful answers
Common questions
Does adding an additional insured give that party its own separate limits?
Usually not. An additional insured generally shares the limits on your policy, so a claim paid on their behalf draws on the same limits that protect your business. Read the endorsement and ask the insurer how it applies on your policy.
What is the difference between a blanket and a scheduled additional insured endorsement?
A scheduled endorsement names a specific person or company. A blanket endorsement adds anyone you have agreed in a written contract to add, often with conditions such as signing that contract before the work starts.
Can I add my landlord as an additional insured partway through the policy term?
Policies can usually be endorsed mid-term. Send the agent or insurer the landlord’s exact legal name, the lease’s insurance section and the date the lease begins, then request an updated certificate and endorsement page.
Why does a general contractor want completed operations additional insured coverage?
Problems with finished work can surface long after a crew leaves the site. Completed operations coverage extends the contractor’s protection to that period, which is why many subcontracts request it for a stated time after the project ends.
Is being named on a certificate of insurance the same as being an additional insured?
No. A certificate is evidence of coverage, and California requires it to state that it does not change the policy. Additional insured status comes from an endorsement attached to the policy itself.
