The lease decides more about your insurance than most owners realize. Whether you sign a triple net or a gross lease quietly sets who is supposed to buy the building coverage, who carries liability, and who insures the contents. The trouble is that lease language and actual policies are written at different times by different people, and they drift apart. When they do, the gap sits invisible until a claim forces it into the open.
How a triple net lease splits insurance
Under a triple net lease, the tenant generally reimburses the property costs, including insurance, taxes, and maintenance, on top of base rent. But reimbursing the premium is not the same as holding the policy. In many triple net arrangements the owner still carries the building coverage and simply passes the cost through. In others the tenant is required to insure the structure directly. The common triple net misconception is assuming net means the tenant handles everything, when the lease language actually controls who buys what.
How a gross lease splits insurance
A gross lease flips the cash flow. The owner generally pays the building and liability premiums and folds those costs into a single rent number. The tenant usually still insures its own contents and carries its own liability, but the structure sits on the owner’s policy. The tenant pays for insurance indirectly, through the rent, rather than through a separate reimbursement line. For the owner, the coverage responsibility is clearer, because it stays in one place.
Where the gaps open
The gap almost always shows up between what the lease says and what the policies do. A lease may require the tenant to insure the building, name the owner as an additional insured, or carry certain limits. If no one collects and reads the certificate of insurance, none of that is confirmed. The coverage may never have been bought, or the owner may never have been added. The risk transfer the lease promised only works if the paperwork behind it is real.
Which structure protects you
Neither lease type is safer on its own. What protects you is alignment between the lease and the policies. Under a triple net lease, that usually means keeping or verifying building coverage and checking the tenant’s certificate every year. Under a gross lease, it means carrying the right building and liability limits yourself and confirming the tenant insures its own contents. The deciding factor is not the label on the lease, it is whether the actual policies match what the lease assigned.
Questions to ask your advisor
- Under my lease, who is supposed to insure the building, and who actually holds the policy?
- Am I reimbursed for insurance, or is the tenant required to buy it directly?
- Have I collected and read the tenant’s certificate this year?
- If the tenant is required to name me, does the certificate confirm it?
- Should I keep my own building coverage even if the lease puts it on the tenant?
The lease and the insurance are supposed to tell the same story, and over a long term they quietly stop matching. A triple net lease can leave the owner exposed when a certificate is never checked, and a gross lease can leave contents uncovered when responsibilities are assumed rather than confirmed. A coverage review reads your lease against your policies, checks the certificates, and shows you exactly where the two have drifted apart before a claim does it for you.
