California Commercial Lease Insurance Checklist: What to Ask Before You Sign

Why your lease drives the insurance conversation

A commercial lease allocates responsibility for the building, the tenant's improvements, equipment, repairs after damage, and rent obligations — and those allocations shape what each party should insure. There is no automatic rule that the landlord or the tenant insures a given item; the lease and the policies control. The California Department of Insurance encourages reviewing your current policy's classifications, limits, exclusions, and endorsements, and the same discipline applies to a lease: read the insurance and repair clauses before you sign, then match your coverage to what the lease actually requires. This checklist is a set of questions to ask, not a universal mandate or a lease template.

A responsibility worksheet before you sign

For each item below, identify four things: who owns it, who must repair or replace it after damage, who insures it, and what interest, limits, and forms apply. These are questions for your actual lease and policies — the answers are not automatic and can vary by lease and by insurer. Confirm each with the lease language and your insurer's authorized representative, and send anything you cannot resolve to your broker or counsel before signing.

• Building / shell — Who owns the structure? Who must repair it after a covered cause of damage? Who insures it and at what limits and valuation (replacement cost vs. actual cash value)? Does the lease require the tenant to insure the building, or only the landlord?
• Business equipment and inventory — Who owns the tenant's equipment, fixtures, and inventory? Who insures them, and are they covered at the premises and off-premises? Are values current and adequate?
• Tenant improvements / leasehold improvements — Who paid for build-outs and improvements, and who owns them? Who must repair or replace them after damage? Who insures them, and does the lease require a specific interest or limit?
• Repairs after damage — After a covered loss, who is responsible for restoring the premises, the improvements, and the equipment? Does the lease require the tenant to repair even when the landlord insures the building? Are code-upgrade (ordinance or law) costs addressed, and by whom?
• Rent obligations — Does the lease require continued rent after a damage event? Is there any abatement, and under what conditions? Is lost rental income insured, and by whom? Do not assume automatic rent abatement or restoration — check the lease and the policy.

Insurance requirements and additional insureds

Many leases require the tenant to carry specific coverages and limits and to name the landlord as an additional insured. Being named an additional insured extends certain rights under the tenant's policy, but those rights arise from the policy's terms and endorsements — not from the lease alone. Confirm the required endorsements are actually attached, including any primary/non-contributory wording, waiver of subrogation, and ongoing/completed operations if the lease calls for them. For a detailed endorsement-review workflow, see our guide to certificates of insurance and additional insured requests.

• Required coverages and limits — list each coverage the lease requires (general liability, property, etc.) and the minimum limits
• Additional insured / certificate holder — confirm whether the landlord must be an additional insured, a certificate holder, or both, and which endorsement applies
• Primary and non-contributory / waiver of subrogation — confirm these are endorsed if the lease requires them
• Notice rights — ask the insurer's authorized representative what cancellation or renewal notice rights the policy actually provides; do not assume a default period

Income, interruption, and off-premises dependencies

If your business depends on the leased premises, business interruption coverage may address lost income and extra expense after a covered cause of loss — but whether it applies depends on your policy's actual triggers, waiting period, and restoration period, so check those against your lease's rent and repair obligations. For a detailed set of questions on triggers, waiting periods, and sublimits, see our business interruption insurance questions guide rather than duplicating that topic here.

A hypothetical San Luis Obispo cafe build-out

Suppose a cafe tenant in a San Luis Obispo building signs a lease for a build-out that adds a kitchen, fixtures, and seating. This example illustrates the questions to ask — it does not promise that any claim is paid. Whether coverage applies depends on the lease, the policy wording, exclusions, limits, and underwriting.

• Building / shell: Does the lease require the tenant to insure the building, or only the landlord? Who repairs the shell after a covered fire?
• Fit-out and improvements: Who owns the kitchen build-out and fixtures? Who must repair or replace them after damage, and who insures them and at what interest and limits?
• Equipment: Who insures the owned and leased kitchen equipment, and is spoilage from a covered breakdown addressed?
• Repairs after damage: Does the lease require the tenant to restore the premises even when the landlord insures the building? Are code-upgrade costs assigned to anyone?
• Rent: Does the lease require continued rent during a closure for repairs? Is any abatement conditional, and is lost income insured?
• Handoff: Send any item you cannot confirm to your broker or counsel before you sign — do not assume the lease or a policy automatically allocates it.
