What it does
When a tenant's policy insures the building it occupies, CP 12 19 adds the building owner shown in the Schedule as a Named Insured. That status applies only to coverage for direct physical loss or damage to the scheduled building. The Schedule lists the premises, building, building description, and the owner's name and address. The owner gets direct rights under the policy for its building, beyond what a loss payee clause gives.
Editions
The 06 07 edition was titled "Additional Insured – Building Owner", even though its wording made the owner a Named Insured. ISO's 2025 commercial property filing introduces the 06 26 edition under the title "Named Insured – Building Owner", which matches what the endorsement does. In Arizona, ISO's forms filing CF-2025-OFR25 (SERFF ISOF-134728874, approved February 3, 2026) makes the 06 26 endorsements effective June 1, 2026 for new and renewal policies. Effective dates in other states depend on each state filing and on carrier adoption. Commercial property carriers have filed to adopt the 06 26 edition. Two carriers in Massachusetts, for example, filed it for policies effective October 1, 2026.
Who needs it
Tenants under leases that make them responsible for insuring the building: single-tenant net-leased buildings, restaurants and retail on ground leases, and industrial tenants. Landlords and their lenders often require it.
Quoting and selling notes
- Read the lease's insurance section. If the landlord only needs to be paid for its building, Loss Payable Provisions (CP 12 18, building owner clause) may be enough. If the lease calls for the landlord to be an additional insured or named insured on the property policy, use CP 12 19.
- Liability additional insured status for landlords is a separate CGL endorsement. CP 12 19 does not give the landlord liability coverage.
- Make sure the building limit and valuation in the tenant's policy meet the lease requirement, typically full replacement cost.
