Your commercial lease is only as strong as the insurance it actually transfers, and most leases transfer less than the owner believes. The insurance clause gets treated as boilerplate, the certificates pile up unread, and the additional insured wording is assumed rather than verified. Then a claim arrives, the tenant’s coverage does not respond the way you expected, and the transfer you counted on turns out never to have existed. Getting this right is part lease language and part verification, and both have to be real.
What every tenant should carry
At a minimum, require commercial general liability at a limit appropriate to the space and use, with the landlord named as additional insured, plus coverage for the tenant’s own property and improvements. Depending on the tenant, add business personal property coverage, workers compensation where there are employees, umbrella or excess liability, and a waiver of subrogation. The requirements should differ by tenant type, an industrial tenant is not an office tenant, rather than a single generic clause applied to everyone.
The two clauses that do the work
Two provisions carry most of the transfer. Additional insured status extends the tenant’s liability policy to protect you for claims arising from their operations or use of the space, so the tenant’s insurer responds when you are named, not yours. A waiver of subrogation stops each side’s insurer from suing the other after a covered loss. Without additional insured, the tenant’s insurance protects only the tenant; without the waiver, a covered property loss can become a lawsuit between landlord and tenant. Both belong in a well-built lease.
A certificate is not proof
Here is the verification trap. A certificate of insurance summarizes a policy but grants you no rights; an endorsement actually amends the policy to add you as additional insured. A certificate can show additional insured status that was never endorsed onto the policy, so relying on the certificate alone leaves you exposed. Verifying the endorsement, confirming the coverage is in force, and tracking renewals are what turn lease language into actual protection. This is exactly the kind of gap that surfaces as a denied or misdirected claim.
It supplements your coverage, not replaces it
Even perfect tenant requirements do not eliminate your exposure. Claims involving common areas, the structure, conditions you control, or holes in a tenant’s coverage still reach you, which is why you carry your own lessor’s risk liability and often an umbrella above it. Tenant insurance and your own program are layers that work together, and they should be designed that way alongside how you hold and structure the buildings.
Review the leases and the coverage together
The way to make lease risk transfer real is to align the lease language, the verification process, and your own liability program. A coverage review checks that your leases require the right coverage, that the certificates and endorsements are actually in force, and that your own liability fills the gaps the leases leave, so the transfer holds when a claim tests it.
