What Insurance Do I Need Before Signing a Commercial Lease?

A commercial lease almost always tells you what insurance to carry, and signing without checking can leave you in breach or underinsured. Here is what to look for before you commit.

What leases commonly require

Most commercial leases require general liability at a stated limit, name the landlord (and sometimes a property manager or lender) as additional insured, and ask for a waiver of subrogation. Many also make you responsible for insuring your improvements and betterments, the build-out you add to the space, and some require business income coverage.

Where tenants get caught

The common problems are limits below what the lease requires, missing additional insured or waiver endorsements, and assuming the landlord’s policy covers your build-out and contents. It usually does not. Each requirement is specific, and meeting it is about the exact endorsements, not just having a policy.

Read the insurance section before you sign

The insurance and indemnity sections are where the obligations live. Reading them before signing tells you whether your current coverage qualifies or what you would need to add. It is far easier to address before the lease is executed than after.

Questions to ask your advisor

  • Do my current limits meet what this lease requires?
  • Are the additional insured and waiver endorsements actually on my policy?
  • Are my improvements and betterments covered, and to what value?
  • Does the lease require business income coverage I do not carry?
  • Who else does the lease want named, and are they listed correctly?

What to do

Send the insurance section to your agent and compare it to your coverage. Confirm the limits, the additional insured and waiver endorsements, and whether your improvements are covered. Then sign knowing your coverage actually meets the lease.

What many people don't realize

The part that catches owners off guard

  • Leases set specific insurance obligations in their fine print.
  • Your improvements are usually your responsibility, not the landlord's.
  • It is easier to meet the requirements before you sign than after.
  • The exact endorsements matter, not just having a policy.

What we see most often

Tenants sign first and read the insurance section later, then scramble to add endorsements the lease already required. By then the opening is on the calendar and the pressure is on. Reading the insurance and indemnity clauses before you commit turns a scramble into a checklist.

Most of the friction is not about whether you have insurance. It is about whether your policy carries the exact limits and endorsements the lease names. Those are specific, and they are far easier to line up before the lease is executed.

A real example

A tenant signed a lease and set an opening date, then learned the required additional insured and waiver endorsements were not on the policy. The details are illustrative, but the holdup is common.

Adding the endorsements took a few days the schedule did not have. Checking the insurance section before signing would have surfaced the requirement while there was still time to meet it calmly.

When to review

It may be time for a coverage review if:

  • You are signing or renewing a commercial lease
  • A landlord requires specific limits
  • The lease names additional insured or waiver wording
  • You are building out or improving the space
  • A property manager or lender wants to be named

Frequently asked

Frequently asked

What insurance does a commercial lease require?
Most require general liability at a set limit, additional insured status for the landlord, and often a waiver of subrogation. Many also ask you to insure your improvements and sometimes carry business income coverage.
Does my landlord's insurance cover my business?
Generally no. The landlord's policy typically covers the building and their interests, not your contents, improvements, or liability. Those are usually your responsibility.
Should I review a lease before signing?
It is wise to. The insurance section sets obligations that are much easier to meet before you sign. A quick review can confirm your coverage qualifies or show what to add.
What are improvements and betterments?
They are the build-out and upgrades you add to a leased space. Leases often make the tenant responsible for insuring them, since the landlord's property policy generally does not.
What is a waiver of subrogation?
It is a clause where each party agrees their insurer will not pursue the other after a loss. Leases commonly require it, and it usually needs a matching endorsement on your policy.
What happens if my coverage does not meet the lease?
You could be in breach of the lease or underinsured for a loss. Catching the gap before signing lets you add the right endorsements rather than discovering it during a claim or audit.
