Of everything on a seasonal lot’s insurance application, “additional insured” is the phrase that causes the most back-and-forth emails. Here’s what it actually does.
The short version
Adding someone as an additional insured extends part of your general liability policy to cover them too — but only for claims tied to your operation on their property. It doesn’t give them their own separate policy, and it doesn’t cover anything unrelated to your business.
Why a landlord asks for it
If a customer gets hurt on the lot and sues both you and the property owner, additional insured status means your policy is positioned to respond to claims against the landlord too, not just against you. Without it, the landlord could be defending a claim with their own separate policy, which is exactly what they’re trying to avoid by asking for the status in the first place.
How to answer it on the application
The application asks whether a landlord or venue already requires additional insured status, and whether you want to provide their exact name and address now or later. If you already know the answer, providing it now saves a step — but it’s fine to wait until closer to when the certificate actually gets issued.
What it doesn’t do
It doesn’t make the landlord a co-owner of your business, doesn’t cover their property against damage caused by something other than your operation, and doesn’t replace their own general liability policy. It’s a narrow extension, not a blanket one.
