You found your commercial space. You negotiated the rent. Now the landlord or property manager is asking for a COI before they hand over the keys — a certificate of insurance listing them as additional insured with specific GL limits, endorsement wording, and sometimes a fire legal liability requirement you weren't expecting. This is the moment most new business owners realize their coverage isn't quite right.
A California commercial lease COI requirement typically includes: $1M–$2M general liability naming the landlord as additional insured, business property coverage for tenant improvements, workers comp if you have employees, and primary/non-contributory wording that prevents the landlord's insurer from being drawn into your claim.
What does a California commercial lease insurance section actually say?
Definition: The insurance section of a California commercial lease — sometimes called the "indemnification and insurance" article — is a contractual requirement that the tenant must carry specific insurance types at minimum limits for the duration of the lease. Failure to maintain the required coverage is typically defined as a material breach of the lease, giving the landlord the right to terminate.
Most California commercial leases written by professional property management companies include at least the following requirements for the tenant:
- Commercial general liability (GL): Coverage for bodily injury and property damage claims arising from the tenant's operations. The landlord requires minimum limits — most commonly $1,000,000 per occurrence / $2,000,000 aggregate for a standard retail or service space. Higher-traffic or higher-hazard businesses (restaurants, liquor stores, salons) may face $2,000,000 per occurrence requirements.
- Landlord named as additional insured: The lease requires the landlord's legal name (and often the property management company's name) to be listed on the tenant's GL policy as additional insured. This extends the tenant's GL coverage to defend the landlord in third-party claims arising from the tenant's operations.
- Business personal property / tenant improvements: Coverage for the tenant's own furniture, equipment, fixtures, and leasehold improvements. The lease may specify that tenant improvements built out at the landlord's expense must also be covered.
- Workers compensation: If the tenant has employees, California Labor Code §3700 requires workers comp regardless of the lease — but most commercial leases also state this requirement explicitly and may ask for a copy of the workers comp certificate.
Insurance City's parent operation serves 4,500+ active customers across three California offices and wrote 2,080 new policies in 2025. Helping new commercial tenants get the right COI language before lease signing is one of the most common day-one requests from restaurant, salon, and retail clients throughout the San Joaquin Valley.
What lease clauses mean in plain English
Commercial leases use insurance-industry jargon that is not always obvious. Here are the most common clauses and what they actually mean for your insurance program:
| Lease Clause | What It Means | Action Required |
|---|---|---|
| Additional insured | Landlord's name appears on your GL policy; your insurer defends them in covered claims | Add landlord by name at policy binding; give broker the exact legal entity name |
| Primary and non-contributory | Your policy pays first; your carrier cannot ask the landlord's insurer to share the cost | Request this endorsement explicitly — it must appear on the COI |
| Waiver of subrogation | Your insurer gives up the right to sue the landlord to recover what it paid you | Needs a waiver of subrogation endorsement added to GL and workers comp |
| Fire legal liability | Coverage for damage you cause to the rented premises by fire | Usually included in GL at $100,000–$300,000; confirm the limit meets the lease requirement |
| 30-day notice of cancellation | Landlord must receive 30 days' notice before your policy can be cancelled | Standard endorsement — confirm it appears on the COI ACORD form |
| Blanket additional insured | Policy automatically covers any entity required by written contract — including your landlord — without needing to schedule them by name | Confirm your policy has a blanket AI endorsement if you have multiple landlords or properties |
GL limits required by property type in California
What a landlord requires on the COI depends heavily on the type of property and the tenant's business. These are typical ranges — always verify against your specific lease:
| Property / Tenant Type | Typical GL Minimum Required | Additional Common Requirements |
|---|---|---|
| Small office or retail strip mall | $1M per occurrence / $2M aggregate | Workers comp, fire legal liability |
| Restaurant or food service | $1M–$2M per occurrence / $2M–$4M aggregate | Liquor liability if ABC licensed; waiver of subrogation |
| Salon, barbershop, nail salon | $1M per occurrence / $2M aggregate | Primary and non-contributory; workers comp if employees |
| Auto repair shop | $1M–$2M per occurrence / $2M–$4M aggregate | Garage keepers liability; garage liability vs general GL |
| Liquor store or market with ABC license | $1M–$2M per occurrence / $2M–$4M aggregate | Liquor liability required; waiver of subrogation |
| Medical or dental office | $1M–$2M per occurrence / $2M–$4M aggregate | Professional liability separate; malpractice not on GL |
How to get the COI before the lease signing
The timeline matters — a landlord who needs a COI by Friday to hand over the keys will not wait a week. Here is the step-by-step process:
- Get the COI requirements from the landlord before you shop for insurance. Ask for the "insurance exhibit" or "Exhibit B" of the lease — this is where the specific requirements are listed. Take note of: the required GL limits, whether primary/non-contributory wording is required, whether a waiver of subrogation is required, and the exact legal name(s) of the landlord and property management company as they want to appear on the COI.
- Bring the lease's insurance requirements to your broker when you shop for the BOP or GL. The requirements must be built into the policy at binding — not added after. Tell your broker: "This is a commercial lease at [address], here are the required limits and endorsements, and here is the additional insured's exact legal name."
- Bind the policy. For most standard retail and office classes, a GL policy or BOP can be quoted and bound within one to two business days. Specialty businesses (restaurants with full bars, auto repair, medical) may take a day or two longer depending on the carrier.
- Request the COI with the correct additional insured and endorsements. Once the policy is bound, your broker issues the ACORD 25 COI. This is the standard industry form. It lists your policy number, effective dates, limits, and the additional insured. If the lease requires specific endorsement form numbers, those must be attached.
- Submit the COI to the landlord. Keep a copy for your records. If the lease has an annual renewal requirement (many do), set a calendar reminder 60 days before your policy expiration to renew the policy and re-issue the COI before the old one expires.
- Maintain continuous coverage. A gap in coverage — even a few days — can trigger a lease default clause. Some landlords require automatic notification if a tenant's policy is cancelled or non-renewed. That's the "30-day notice of cancellation" endorsement on the COI.
What if the landlord requires coverage my BOP doesn't include?
Leases for restaurants, bars, or other alcohol-serving businesses often require liquor liability — which is not included in a standard BOP and must be added as a separate endorsement or standalone policy. Auto repair shops may need garage liability instead of standard GL — it is a different coverage form designed for businesses that take custody of customer vehicles. Medical tenants may need a specific professional liability limit listed on the COI.
The key point: match the lease requirements against your policy before you sign. An independent broker reads both documents and identifies the gaps. A captive agent representing a single carrier may not have the products to fill every requirement.
Can a landlord require coverage that California law says I don't need?
Yes — in almost all cases. A commercial lease is a private contract, and landlords can require higher insurance limits or additional coverage types than California law mandates. California law requires workers comp (Labor Code §3700) and minimum auto liability (Vehicle Code §16056) — but does not set minimums for commercial GL or property coverage. Landlords set those minimums by contract, and tenants either meet them or do not get the lease.
The one area where lease requirements can be contested: if the lease requires the tenant to cover the landlord's own negligence under the indemnity clause, California Civil Code §1668 and §2782 limit a landlord's ability to require a tenant to indemnify them for the landlord's own negligence in residential contexts — though commercial lease law in California is generally more permissive for sophisticated parties.

Frequently asked questions
What insurance does a commercial tenant need in California?
Most California commercial leases require: general liability ($1M–$2M per occurrence), business property / tenant improvements coverage, and workers comp if the tenant has employees (required by California Labor Code §3700). The lease's insurance exhibit specifies the exact limits, endorsements, and additional insured language. Read it before shopping for insurance so the policy is structured correctly from day one.
What does "additional insured" mean on a commercial lease COI?
Additional insured status means the landlord is named on your GL policy. If a third party sues the landlord over an incident arising from your business operations, your insurer defends and pays on behalf of the landlord, up to your policy limits. You pay for the coverage; the landlord gets the protection. It's standard practice in commercial real estate throughout California.
What is "primary and non-contributory" wording on a COI?
Primary and non-contributory means your policy pays first — before the landlord's own insurer is asked to contribute — and your carrier will not seek contribution from the landlord's insurer. Without it, carriers can dispute who pays first, delaying claims and potentially drawing the landlord's policy into a claim they expected your insurance to handle. Most professional property managers require this endorsement on the COI.
How fast can I get a COI for a commercial lease?
Same-day in most cases once the policy is bound. Bring the lease's insurance requirements before binding — the additional insured, limits, and endorsements must be written into the policy at inception, not added afterward. An independent broker who handles commercial accounts regularly can quote, bind, and issue the COI in one to two business days for most retail and service businesses.
