The Triple Net (NNN) Misconception: Why the Owner Still Watches the Insurance

Triple net is one of the most misunderstood phrases in commercial real estate. Owners hear NNN and quietly cross insurance off their list, because the tenant pays for it. That is half true and fully dangerous. A triple net lease generally shifts the cost of property insurance to the tenant. It does not shift the owner’s stake in whether that insurance is adequate, whether it protects the owner, or whether it even stays in force. Paying for coverage and being protected by it are two different things, and the gap between them is where owners get hurt.

What NNN actually shifts

Under a triple net lease, the tenant generally takes on three operating costs beyond base rent: property taxes, insurance, and maintenance. The word net refers to rent that is net of those expenses. So the lease reassigns who pays. That is the entire scope of the shift. It does not decide whose policy responds to a loss, how much coverage the building carries, or whether the owner is named and protected. Those questions are answered by the lease language and the actual policy, not by the label. Understanding who insures what under NNN versus a gross lease is the starting point for getting this right.

The false hand-off

Here is how the misconception plays out. The owner assumes the tenant has insurance handled and stops looking. The tenant, paying the bill, buys the least expensive policy that satisfies the plain wording of the lease. Neither party is watching whether the limit tracks the building value, whether the valuation basis will pay a real loss, or whether the owner is actually protected on the policy. The triple net structure created a feeling of hand-off. The coverage quality did not come along for the ride.

The gaps that open

Several gaps tend to appear once both sides assume the other has it covered. The building can end up insured below its value, which exposes it to a coinsurance penalty on top of a shortfall. The policy may not clearly name or protect the owner’s interest, so a loss raises the question of whose coverage even responds. The valuation basis may pay less than the owner expected. And a policy the owner never watches can lapse quietly, the same way an untracked tenant certificate does. Every one of these traces to the same root: coverage everyone believed was handled somewhere else.

Where the lender comes in

If there is a loan on the building, the lender adds its own layer. Lenders generally carry insurance requirements, including limits and their own protected status, that must be satisfied no matter who pays the premium. When a tenant carries the property policy under a triple net lease, the owner still has to confirm it meets the lender’s terms. A mismatch there can create a problem entirely separate from any physical damage, and it is the owner, not the tenant, who answers to the lender.

How to keep watching without micromanaging

The fix is not to take the cost back. It is to keep an eye on the coverage even when the tenant pays for it. Set clear lease language, reviewed with your attorney, that specifies who carries the property policy, the required limit and valuation basis, how the owner is protected, and the duty to provide certificates and renewals. Then verify it annually. That is the difference between a triple net lease that actually protects the building and one that only feels like it does.

Questions to ask your advisor

Does my lease clearly state who carries the property policy and at what limit and valuation basis?
Am I named and protected on the policy covering my building, or only assuming I am?
Does the coverage a triple net tenant carries meet my lender’s requirements?
How would I know if a tenant-carried policy lapsed or renewed at a lower limit?
Should the tenant carry the property policy directly, or reimburse me for one I control?

Triple net changes who writes the check, not who owns the risk. The building is still yours, and so is the fallout if the coverage behind it is thin. Keep the lease terms tight, verify the policy every year, and NNN becomes what it should be, a cost arrangement, not a blind spot.

What many people don't realize

The part that catches owners off guard

A triple net lease generally shifts the cost of property insurance, taxes, and maintenance to the tenant, not the owner's interest in the building being properly insured.
Who pays the premium and whose coverage actually protects the building are two different questions.
If a tenant carries the property policy, the owner still needs to confirm the limit, the valuation basis, and that the owner is protected.
Gaps open when both sides assume the other party is handling coverage that neither is.
The lease language, not the label triple net, decides who insures what.

The Vantage Point

What we see most often

The phrase triple net does a lot of quiet damage. Owners hear it and mentally file insurance under the tenant's responsibilities, done. But shifting who pays for coverage is not the same as shifting who is protected by it, or whether the coverage is adequate in the first place. The owner still owns the building, still has a mortgage or an interest to protect, and still bears the consequence if the policy behind it is thin or wrong.

What we see is a false sense of hand-off. The owner assumes the tenant has it covered, the tenant buys the cheapest policy that satisfies the letter of the lease, and nobody is watching whether the limit tracks the building value or whether the owner is actually named. The label created comfort. The coverage did not follow.

A real example

Consider a composite example, illustrative only. An owner held a building under a triple net lease and understood that the tenant paid for the property insurance, so the owner stopped tracking it.

The tenant carried a policy that met the bare wording of the lease but was set at a limit below the building value and did not clearly protect the owner's interest. After a loss, the shortfall and the question of whose coverage responded became the owner's problem, despite the tenant paying every premium. Reviewing the lease insurance terms and confirming the coverage each year would have surfaced the gap in advance.

When to review

It may be time for a coverage review if:

You have triple net tenants and assume insurance is fully handled
You do not review the property policy a tenant carries on your building
Your lease does not specify limits, valuation, and owner protection clearly
You are not sure whether you are protected on a tenant-carried policy
You have a lender whose requirements you have not matched to the tenant policy

Frequently asked

What does a triple net lease actually shift?

A triple net lease generally shifts three operating costs to the tenant, property taxes, insurance, and maintenance, on top of base rent. It shifts who pays. It does not by itself decide whose coverage protects the building or whether the coverage is adequate. Those are set by the lease language and the actual policy, which is why the label alone does not tell you the building is properly insured.

If my tenant pays for insurance, why should I still watch it?

Because paying for a policy and being protected by it are different things. You still own the building and may have a lender to satisfy. If the tenant carries a property policy, you generally want to confirm the limit tracks the building value, the valuation basis is sound, and your interest is protected. Otherwise a loss can expose a gap you paid nothing for but still absorb.

Who should carry the property insurance under an NNN lease?

It varies. In some triple net arrangements the tenant reimburses the owner who carries the policy, in others the tenant carries it directly. Each approach has tradeoffs for control and protection. The right structure depends on the lease, the property, and often lender requirements, and it should be set deliberately rather than assumed from the triple net label.

What gaps open when both sides assume the other has it?

Common gaps include a building insured below its value, a policy that does not clearly name or protect the owner, a valuation basis that pays less than expected, and lapses that go unnoticed. Each one traces back to the same root, both parties believing coverage is handled elsewhere. Clear lease terms and annual verification are what prevent it.

How does a lender fit into a triple net lease?

A lender on the building generally has its own insurance requirements, including limits and its own protected status, that must be satisfied regardless of who pays the premium. If a tenant carries the policy, the owner still has to make sure it meets the lender's terms. A mismatch there can create problems independent of any physical loss.

What should the lease say about insurance?

It commonly specifies who carries the property policy, the required limit and valuation basis, how the owner is protected, minimum liability limits, and the duty to provide certificates and renewals. The precise terms depend on the property and legal review. Clear language is what turns triple net from an assumption into an enforceable arrangement.
