The landlord almost always carries the building insurance; the tenant carries liability for what happens inside
In a commercial lease, the landlord is responsible for insuring the building structure itself — the walls, roof, foundation, and permanent systems like electrical and plumbing. This is called property insurance or building coverage. The tenant does not pay for this directly, though the landlord usually passes the cost to the tenant as part of the lease agreement.
The tenant is responsible for commercial general liability insurance, which covers injuries or damage that happen because of the tenant's business operations. A customer who slips in your store, equipment you damage at a client's site, or a fire you accidentally start — that is your liability insurance, not the landlord's building insurance.
The lease document itself determines who pays what. Some leases require the tenant to reimburse the landlord for building insurance as part of the rent or as a separate line item. Others build it into the base rent. Either way, the landlord holds the policy because the landlord owns the building.
Key Takeaways
- The landlord owns and insures the building structure; the tenant reimburses the landlord for that cost through the lease agreement.
- The tenant must carry commercial general liability insurance to cover injuries, damage, or accidents caused by the tenant's business.
- Your lease specifies whether building insurance is a separate line item or rolled into your base rent payment.
- If the building is damaged and the landlord's insurance does not cover it, the tenant may still be liable depending on what caused the damage and what the lease says.
- Tenants in multi-tenant buildings should verify they are named as an additional insured on the landlord's policy for certain claims.
What the landlord's building insurance covers
The landlord's property insurance covers the structure and its permanent parts: the roof, exterior walls, foundation, built-in HVAC systems, electrical wiring, plumbing, and load-bearing elements. It also typically covers common areas like hallways, lobbies, and parking lots if the building is multi-tenant.
This insurance pays for repairs or rebuilding if the building is damaged by fire, weather, theft, or vandalism. It does not cover the tenant's equipment, inventory, or furniture — those belong to the tenant and are the tenant's responsibility to insure.
The landlord's policy also does not cover liability for injuries that happen because of the tenant's business. If a customer is injured by something the tenant did or failed to do, the landlord's building insurance will not pay for that claim.
What the tenant's liability insurance covers
Commercial general liability insurance protects the tenant from claims of bodily injury, property damage, or personal injury caused by the tenant's business. If a customer slips on a wet floor in your store, or your employee damages a client's equipment at their location, your liability policy covers the legal costs and damages.
Most landlords require tenants to carry a minimum amount of liability coverage — often $1 million per occurrence — and to name the landlord as an additional insured on the policy. This means the landlord is protected under the tenant's policy if someone sues over something the tenant did.
Liability insurance also covers advertising injury (like a false claim in your marketing), products liability (if your product harms someone), and completed operations (claims that arise after you finish a job). The exact coverage depends on the policy and the type of business.
How the lease determines who pays for building insurance
The commercial lease is a contract between you and the landlord, and it spells out who pays for what. Some leases state that the tenant reimburses the landlord for building insurance as a separate monthly charge. Others include insurance costs in the base rent or in a combined "triple net" payment that also covers property taxes and maintenance.
A triple net lease (or NNN lease) requires the tenant to pay the landlord's property taxes, insurance, and maintenance costs on top of the base rent. This is common for retail and industrial spaces. A gross lease includes most or all of these costs in the base rent, so the tenant's payment does not change if insurance costs rise.
Before you sign, ask the landlord for a copy of the current building insurance policy and the annual premium. This tells you what you will be reimbursing and whether the coverage is adequate for your business. If the building is underinsured and suffers major damage, you may face rent increases or a long closure while repairs happen.
What happens if the building is damaged and insurance does not cover it
If the building is damaged and the landlord's insurance does not pay — because the damage is excluded from the policy, or because the landlord did not maintain the policy — the tenant is usually not liable for the landlord's loss. The landlord's failure to insure is the landlord's problem.
However, if the damage was caused by the tenant's negligence or intentional act, the landlord may sue the tenant directly to recover losses. For example, if your employee causes a fire through carelessness, the landlord can pursue a claim against you even if the landlord's insurance does not cover it.
This is why your liability insurance matters: it protects you from claims the landlord might bring. It is also why the lease usually requires you to name the landlord as an additional insured — it encourages the landlord to look to your policy first before suing you.
Multi-tenant buildings and shared responsibility
In a multi-tenant building, the landlord insures the structure and common areas. Each tenant insures their own space and operations. If a fire starts in one tenant's unit and spreads to another, the tenant whose negligence caused the fire is liable to the other tenant, not the landlord.
The landlord's building insurance covers the cost of rebuilding the structure, but each tenant's liability insurance covers claims between tenants. This is why it is important to verify that your liability policy covers the specific risks of your business and the building you occupy.
If you are in a multi-tenant building, ask the landlord for a copy of the building insurance certificate and confirm that the coverage limits are reasonable for the size and type of building. If the building is underinsured, you may want to purchase additional coverage to protect yourself if a major loss occurs.
When a tenant might need to carry building insurance
In rare cases, a commercial lease may require the tenant to carry building insurance instead of the landlord. This happens in triple net leases for large industrial or retail properties, where the tenant essentially operates as the building owner for the duration of the lease.
Some leases also require the tenant to carry business interruption insurance, which covers lost income if the building is damaged and the tenant cannot operate. This is separate from building insurance and protects the tenant's revenue, not the landlord's property.
If your lease requires you to carry building insurance, make sure you understand the coverage limits and what is and is not covered. You should also confirm that the landlord is named as a loss payee, so the landlord receives payment if the building is damaged and the lease is terminated.
Frequently Asked Questions
Can a landlord charge me for building insurance if it is not in the lease?
No. The lease is the contract that governs what you pay for. If building insurance is not listed as a separate charge or included in the base rent, the landlord cannot add it later. If the landlord tries to increase your rent to cover insurance, that is a lease violation unless the lease allows for annual adjustments.
What if the landlord does not have building insurance?
That is the landlord's problem, not yours. You are not responsible for the landlord's failure to insure the building. However, if the building is damaged and uninsured, you may face a long closure or a dispute over whether you still owe rent. This is why it is important to verify the landlord has adequate coverage before you sign the lease.
Do I need to name the landlord as an additional insured on my liability policy?
Most leases require it. Naming the landlord as an additional insured means the landlord is protected under your policy if someone sues over something your business did. It costs little or nothing to add, and it satisfies the lease requirement. Ask your insurance agent to add the landlord before you sign the lease.
What is the difference between property insurance and liability insurance?
Property insurance covers damage to the building and its contents. Liability insurance covers injuries or damage caused by your business. The landlord carries property insurance for the building; you carry liability insurance for your operations. Both are necessary, and they do not overlap.
Can I deduct building insurance from my rent if the landlord does not have it?
Not without a court order. If the landlord fails to maintain building insurance and the lease requires it, you may have grounds to break the lease or sue for breach of contract. Withholding rent without a legal judgment is itself a lease violation. Consult a commercial real estate attorney before taking any action.
