NNN Insurance Charges Explained — What Tenants Really Pay

What Are NNN Insurance Charges?

In a triple-net (NNN) lease, tenants typically reimburse the landlord for property insurance covering the building and common areas. These charges are passed through annually as part of NNN expenses.

Insurance charges usually include premiums for policies such as:

• Property (hazard) insurance
• General liability insurance
• Umbrella or excess liability coverage
• Occasionally flood or specialty coverage

How Insurance Charges Should Be Calculated

1. Landlord pays insurance premiums for the building
2. Total premium cost is identified
3. Costs are allocated using tenant pro-rata share
4. Only lease-permitted policies are passed through

Problems arise when policies, allocation methods, or markups exceed what the lease allows.

Common NNN Insurance Overcharges

• Passing through landlord-specific insurance
• Including excessive umbrella coverage
• Charging for unrelated properties
• Applying admin or management fees on insurance
• Using inflated pro-rata calculations

Insurance is often bundled into reconciliation statements, making these errors hard to spot.

When Insurance Charges Are Not Allowed

Many leases restrict insurance pass-throughs. Charges may be challengeable when they include:

• Landlord business insurance
• Excessive or duplicative policies
• Coverage beyond the leased premises
• Insurance unrelated to operating expenses

Why Tenants Rarely Review Insurance Charges

• Insurance language is dense and technical
• Premiums fluctuate year-to-year
• Statements lack policy-level detail
• Audit windows close quickly

Once the audit window closes, insurance overcharges often become final.

Can NNN Insurance Charges Be Challenged?

Yes. Tenants often have audit rights that allow them to request backup documentation and dispute insurance charges that exceed lease allowances.
