A waiver of subrogation is you giving away your own insurer’s right to chase the other party after it has paid you. The lease writes that promise between two businesses. Whether it survives a claim is decided on the policy side, by a property condition or by a named liability endorsement, and the two work differently.
Subrogation is your insurer standing where you were standing
When a carrier pays a claim, it does not simply absorb the cost. To the extent of what it paid, it inherits whatever rights you had against whoever caused the loss. The legal fiction is neat: the insurer steps into your shoes and brings the claim you could have brought.
Two consequences follow, and both matter to a building owner. First, the right belongs to you before it belongs to the carrier, which is the only reason you are in a position to give it away. Second, it is exercised in your name and out of your relationship — the letter that arrives at your tenant after your fire claim was funded is, from the tenant’s point of view, a letter from you.
Why an owner gives the right away on purpose
At first reading, waiving recovery against a tenant who burned your building looks like poor housekeeping. It is not, and the reasoning is worth having straight before you sign it.
The money travels in a circle. Your property insurer pays you and pursues your tenant; the tenant’s liability insurer defends and eventually funds part of it; two carriers spend money establishing which of them ultimately bears a loss that both were paid to bear. Meanwhile the tenant, who did nothing worse than run a business in your building, is in litigation with their landlord and is deciding at the next renewal whether to stay.
The waiver replaces all of that with a rule agreed in advance: each party looks to its own policies for its own property, and neither hunts the other. That is a sensible allocation between parties who chose to do business together, and it is why the article is standard in institutional commercial leases rather than exotic. It sits alongside the other three clauses that shape a lessor’s risk placement — insurance requirements, indemnity, and improvements — and it is the one owners understand least.
The lease writes the promise; the policy has to perform it
Here is the gap that produces every avoidable dispute on this subject. Your lease is an agreement between you and your tenant. Your insurer never signed it, has usually never seen it, and is not bound by it as a matter of contract.
So the question is never “does the lease contain a waiver”. It is “does my policy accept that I gave one”. Answering it takes two different investigations depending on which side of the program you are asking about.
Property and liability get there by different mechanics
On the property side, the permission is already in the form. A standard commercial property placement carries the ISO Commercial Property Conditions form, CP 00 90. Its transfer-of-rights condition does two things: it moves your recovery rights to the carrier to the extent of payment, and it expressly allows you to waive those rights in writing before a loss occurs. That means a lease article executed while everything was quiet is generally recognized without any endorsement at all — which is genuinely convenient and is also why nobody checks it.
On the liability side, it takes a named endorsement. The general liability form carries its own transfer-of-rights condition and no equivalent standing permission, so the waiver is added by attaching CG 24 04, Waiver of Transfer of Rights of Recovery Against Others to Us, naming the party in whose favor it runs. If your lease requires a waiver on the liability policies and no such endorsement was issued, the promise is a promise and the condition is unchanged. The wider liability picture it modifies is on the general liability page.
One form is permissive by default and one is silent by default. Owners who learn the property answer and generalize it to the whole program have learned the more comfortable half.
Before the loss is the condition, not a formality
The property condition’s permission is expressly about timing. A waiver given in writing before a loss binds the carrier. After a loss, the door narrows sharply — to parties insured by the same policy, or businesses that own or are owned by the insured. A tenant is neither.
The practical rule that falls out of this is unglamorous and absolute: the waiver has to be in place while nothing has happened. A lease amendment negotiated during a claim, however genuinely both parties intend it, arrives after the only moment when it could have worked. So does a waiver added to a renewal that is signed while an unreported incident is already sitting in a maintenance log.
Real-World Scenario: An owner signs a new lease carrying a mutual waiver article, and a fire later starts in the tenant’s equipment and damages the structure. The property claim is reported, adjusted and paid without difficulty. Then a recovery file opens against the tenant, because the lease was never put in front of the carrier and nothing in the policy file recorded that a waiver existed. The tenant’s attorney produces the article, and after a long correspondence the file closes. Nothing was uninsured and no coverage failed. The owner simply spent the months after a fire arguing about a clause they had already agreed to, opposite the tenant they most wanted to keep. The waiver worked. Saying so at binding would have meant it never had to.
Mutual, and married to the insurance article beside it
Commercial waivers are normally reciprocal, and the reciprocity is the point. You waive against your tenant for damage to your building and your rents; your tenant waives against you for damage to their stock, equipment and improvements. Half a mutual waiver protects one party and surprises the other, so the article is worth reading for symmetry before it is read for anything else.
It also has to be read against the clause immediately above it. A waiver that gives up recovery for property losses only makes sense if both parties are actually required to insure the property they own — which is what the insurance article is supposed to establish, and what the allocation under a net lease decides. That interaction is set out in NNN leases: who insures what. A lease that waives recovery and does not require either party to insure has quietly agreed that losses simply lie where they fall.
The income side is often left out of the drafting entirely. If your building is damaged, business income and loss of rents answers the rent that stops, and a waiver written around “property damage” alone may or may not reach the income claim your carrier could otherwise pursue. Whether that matters to you depends on how the measurement works, which is in how loss of rents actually pays.
What the waiver does not do
It is not additional insured status. A waiver stops your carrier pursuing your tenant; it puts nobody on anybody’s policy and grants no defense to anyone. The separate question of getting onto your tenant’s liability policy is what a commercial landlord needs on the tenant’s policy.
It is not indemnity, and in some respects it runs against it. Indemnity moves a loss toward one party; a mutual waiver stops it moving at all where insurance responded. Leases regularly contain both, drafted at different times by different hands, and the interaction between them is a question for your attorney rather than for a broker.
It is not a note on a certificate. What that document establishes and what it cannot is set out in the certificate versus the policy. And it is not automatically carried up into your excess layer — whether the umbrella mirrors a waiver granted below is a question about the umbrella’s own conditions.
The check, in the order the documents were signed
Take the lease first and find the article. Note whether it is mutual, whether it is limited to amounts actually recovered under insurance, and which coverages it names.
Then take the policies. On the property placement, confirm the conditions form and confirm nothing has amended the pre-loss waiver permission. On the liability policies — yours and, through your tenant’s broker, theirs — ask for the waiver endorsement itself. Finally, check the dates against each other, because the only version of this that fails outright is the one where the writing came after the event.
None of it is legal advice; leases are drafted by attorneys and your own governs. General background on how commercial lines are put together is published by the Insurance Information Institute, the Small Business Administration writes the tenant-side view of the same paperwork, and the filed forms behind all of it are regulated by your own state department, indexed through the National Association of Insurance Commissioners with consumer material alongside.
If your lease has a waiver article and you have never confirmed the policy accepts it, that is a question with a same-week answer. Send us the article and the conditions form, and the answer is either yes or a short list of endorsements to request.
