Which of the following events would trigger the end to a commercial property Builders Risk Coverage Form?

The end of a commercial property Builders Risk Coverage Form is primarily triggered when the building is completed. This type of policy is specifically designed to cover properties that are under construction, protecting against various risks until the structure is finished. Once the building reaches completion, the purpose of the Builders Risk insurance is fulfilled, and the coverage ceases, as the property can then be covered under a standard commercial property policy.

While the insurance term expiring and non-payment of premiums can also lead to the termination of coverage, these situations are not specific to the nature of Builders Risk insurance. Additionally, the installation of the last fixture could imply nearing completion, but it does not definitively signify that the building is complete. Thus, the completion of the building itself is the clear and definitive event that triggers the cessation of a Builders Risk policy.
