A retail tenant signs a lease requiring $2 million in general liability coverage. Six months later, a customer slips and falls in their store, sustains a spinal injury, and files a $1.8 million lawsuit-naming your property in the claim. You pull the tenant's certificate of insurance. It shows $1 million in coverage. The tenant never updated their policy after signing. You are now exposed for the gap.
This scenario plays out across commercial portfolios every year. According to industry data, 70% of certificates of insurance are non-compliant at first receipt, and uninsured incidents routinely exceed $500,000 in uncovered losses. The problem isn't that landlords don't set requirements-it's that they don't systematically verify them clause by clause.
What Commercial Leases Must Require
Commercial lease insurance requirements vary by property type, tenant use, and jurisdiction, but most well-drafted leases include the following coverage categories:
| Coverage Type | Typical Minimum | Notes |
|---|---|---|
| Commercial General Liability (CGL) | $1M per occurrence / $2M aggregate | Higher for food service, manufacturing, or heavy foot traffic |
| Property Insurance | Replacement cost value | Tenant's personal property and improvements |
| Workers' Compensation | Statutory limits | Required in all states for employees |
| Employers' Liability | $500K per occurrence | Supplements workers' comp |
| Commercial Auto | $1M combined single limit | Required if tenant uses vehicles on premises |
| Umbrella / Excess Liability | $2M-$5M | Stacks over GL, auto, and employers' liability |
| Business Interruption | 12 months of gross revenue | Protects tenant's ability to pay rent |
General Liability: The Non-Negotiable
General liability is the foundation. For most retail and office tenants, the minimum should be $1 million per occurrence and $2 million aggregate. For restaurant, medical, or manufacturing tenants, those numbers should increase to $2 million per occurrence and $4 million aggregate.
The lease must also specify that the landlord and property management company are listed as additional insureds on the CGL policy-not just named on the certificate. The additional insured endorsement is what actually extends coverage. A COI without the underlying endorsement is worthless.
Property and Tenant Improvements
If the landlord funded tenant improvements, the lease should require the tenant to insure those improvements at replacement cost. Many leases specify "betterments and improvements" coverage. This protects the landlord's capital investment if the space is damaged.
Umbrella Requirements: Who Needs What
For anchor tenants in retail centers, hospitality tenants, or any tenant operating in a high-litigation environment (restaurants, gyms, childcare), umbrella requirements of $5 million or more are standard. For small office tenants with limited public exposure, $2 million is often sufficient.
The Additional Insured Problem
The most common-and costly-gap in commercial lease insurance compliance is the additional insured designation. Landlords routinely accept a COI that lists them in the "certificate holder" box without verifying that an AI-2010 or equivalent endorsement has actually been issued.
The certificate holder box means the landlord gets notified if the policy is canceled. It does not mean the landlord is covered. The additional insured endorsement is what triggers coverage for the landlord's own liability arising from the tenant's operations.
Require the following language in your lease:
"Tenant shall cause Landlord and Landlord's property manager to be named as additional insureds on all commercial general liability policies on an ongoing, primary, and non-contributory basis."
Waiver of Subrogation
Every commercial lease should also require a waiver of subrogation on the tenant's property policy. Without it, if a tenant's pipe bursts and damages a neighboring tenant's space, the tenant's insurer can sue the landlord-even though the landlord was managing the building properly.
Setting Requirements by Property Type
Office buildings: Focus on CGL, workers' comp, and umbrella. Most office tenants have low physical risk but moderate liability exposure from visitors.
Retail centers: Increase CGL minimums; add liquor liability if any food/beverage tenants are present. Require product liability for retailers selling physical goods.
Industrial/warehouse: Require full property coverage at replacement cost. Add pollution liability for any tenants working with chemicals or hazardous materials.
Medical office: Add professional liability (malpractice) requirements. CGL alone does not cover professional errors in medical settings.
How to Enforce Lease Insurance Requirements
Most landlords collect a COI at lease signing and never look at it again. The result: coverage lapses silently, policies renew at lower limits, and endorsements disappear-all without the landlord's knowledge.
An effective enforcement process requires:
- Collecting a COI before the tenant takes possession
- Verifying each coverage line against the lease requirement-not just eyeballing the form
- Confirming the additional insured endorsement is actually on file
- Tracking policy renewal dates and requesting updated COIs before expiration
- Escalating to the tenant in writing when gaps are identified
This process, done manually across a 50-tenant building, costs an estimated $36,400 per year in staff time. Automated compliance tools that read the lease and compare it against the COI clause by clause can eliminate most of that cost.
Frequently Asked Questions
Q: Can I just use a standard COI form to verify compliance? A: No. The ACORD 25 certificate form is a summary document and explicitly states it "confers no rights upon the certificate holder." You need to verify the underlying policy endorsements match your lease requirements.
Q: How often should I collect updated COIs from tenants? A: At a minimum, annually upon policy renewal. For high-risk tenants (food service, medical, fitness), consider semi-annual checks. Always collect a new COI immediately after any tenant modification or renovation project.
Q: What happens if a tenant is uninsured when an incident occurs? A: Your property insurance may cover the claim, but you'll pay the deductible, lose claims-free discounts, and potentially face coverage denial if you failed to enforce your own lease requirements. In some jurisdictions, failure to enforce can also constitute negligence.
Q: Do I need to verify workers' comp separately from GL? A: Yes. Workers' comp is a separate policy from CGL and covers a fundamentally different risk. A tenant with no employees may not need it, but any tenant with staff on premises requires it by law in most states.
