Premises Liability When Taking the Keys for Commercial Build-Out in California

Commercial tenants in California often face insurance gaps between taking the keys for build-out and binding permanent business coverage. Here is what to review before tenant improvements begin.

When you sign a commercial lease in California and the landlord hands over the keys for build-out or tenant improvements, a common misconception is that your standard business insurance will fully protect you from day one. In reality, there is often a significant coverage gap during the construction and renovation phase — and many tenants cannot obtain a full, permanent policy until the build-out is nearly complete.

The Coverage Gap During Build-Out

Most commercial leases allow early access or possession specifically for tenant improvements (build-outs). During this period, the space is typically under the tenant’s control for construction purposes. This creates several insurance challenges:

• Standard Commercial General Liability (CGL) policies are designed for ongoing business operations, not active construction or renovation work. Many carriers will either decline coverage, add heavy exclusions, or require much higher premiums when they learn that major build-out work is still underway.
• Property insurance (including coverage for tenant improvements and betterments) often faces issues with vacancy or unoccupied premises exclusions. While California courts have recognized a “construction exception” in some cases, it is not guaranteed and depends heavily on policy wording.
• Builders risk / course of construction policies (usually carried by the landlord or general contractor) primarily cover physical damage to the building and materials — not liability for injuries to third parties or damage caused by the construction activities themselves.

As a result, tenants frequently find themselves in a gray area: they have keys and are responsible for the space, but traditional “full” commercial insurance is not yet available or is severely limited until the work is substantially finished and the actual nature of the business operations is known.

Why Insurers Wait Until Build-Out Is Nearly Complete

Insurance carriers underwrite commercial policies based on the specific risk profile of the business that will ultimately occupy the space. Key factors include:

• Type of business and its operations
• Customer traffic patterns
• Equipment and inventory being installed
• Specific hazards (cooking equipment, hazardous materials, heavy machinery, etc.)

Until the build-out is far enough along for the insurer to evaluate these factors accurately, they are reluctant to bind a permanent policy. This is especially true for restaurants, retail with high public traffic, medical offices, or any occupancy involving specialized equipment or processes.

What Coverage Is Typically Needed During the Interim Period?

During active build-out, tenants (or their contractors) should consider one or more of the following:

• Owners and Contractors Protective Liability (OCP) — Provides liability coverage for the tenant’s interest during construction.
• Contractor’s General Liability with appropriate endorsements for the renovation work.
• Premises liability coverage specifically for the period of early possession.
• Builders risk (if not already provided by the landlord) for physical damage to improvements and materials.

Landlords almost always require proof of insurance and additional insured status before granting access. Failing to have the right coverage in place can delay your build-out or expose you to significant out-of-pocket liability.

Practical Takeaways for California Tenants

1. Review the lease carefully — Look for early access clauses, insurance requirements during construction, and indemnification provisions.
2. Coordinate with your insurance broker early — Ideally before signing the lease. A broker experienced in commercial lines can help structure interim coverage so there are no gaps between taking possession and opening for business.
3. Expect the final policy to come later — Plan your timeline so that permanent coverage is bound only after build-out is substantially complete and the insurer has the information they need.
4. Document everything — Keep records of all insurance certificates, endorsements, and communications with the landlord regarding access and responsibilities.

Bottom Line

Taking the keys for a commercial space in California is an exciting milestone — but it also marks the beginning of a period where your insurance needs are more complex than many tenants expect. Standard full commercial policies are often unavailable until build-out is nearly finished precisely because insurers need to understand the final risk. Working with an experienced commercial insurance broker can help you bridge that gap with the right interim coverage so you stay protected from the moment you take possession.
