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 as expected, and the transfer the owner counted on turns out never to have existed. This guide is about closing that gap. It is the companion to our broader commercial property owner’s insurance guide, focused on the leases.
What to require, and why it varies by tenant
Start with the baseline every commercial tenant should carry: general liability at a limit suited to the space, the landlord named as additional insured, and coverage for the tenant’s own property and improvements. From there it varies. An industrial tenant carries different exposure than an office tenant, so requirements should differ by tenant type rather than a single clause applied to everyone. Workers compensation, umbrella, and waivers come in depending on the risk.
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 use of the space, so their insurer responds when you are named. 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 you and your tenant. Both belong in a well-built lease.
Why a certificate is not proof
Here is the verification trap that catches the most owners. 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, so relying on the certificate alone leaves you exposed. Verifying the endorsement, confirming coverage is in force, and tracking renewals are what turn lease language into actual protection, and the failure here is almost always administrative rather than legal.
It supplements your coverage, it does not replace 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 transfer and your own program are layers. Designing them together, and coordinating them with how you hold and structure the buildings, is what makes the protection hold.
Build a repeatable system across the portfolio
On one building, you can manage this by hand. Across a portfolio, you need a process: lease language that requires the right coverage by tenant type, a collection process that verifies endorsements and waivers rather than just filing certificates, and tracking that catches lapses and renewals. The system that tracks compliance is as important as the clause itself, because the gap that hurts you is almost always a certificate that expired or an endorsement that was never issued.
Where to start
The fastest way to find your exposure is a tenant insurance and lease risk review, which 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. A coverage review is a good first step, because it surfaces the lease-transfer gaps alongside the rest of your program.
