Which event triggers the end of a commercial property Builders Risk Coverage Form?

The Builders Risk Coverage Form is designed to provide insurance coverage for buildings under construction. It typically terminates upon specific events that indicate the completion or significant milestones in the construction process. When the building is accepted by the purchaser, it signifies the transition of responsibility from the contractor or builder to the new owner. This acceptance is a clear indicator that the construction is effectively complete, thus triggering the end of Builders Risk coverage.

The end of coverage is essential for limiting the risk exposure once the building is no longer under construction, and the property is now deemed to have a different insurance requirement. Therefore, this event is pivotal as it aligns with the primary function of the Builders Risk form, making it the correct answer.

The other options, while they may suggest issues during construction, do not mark the definitive completion or acceptance of the building, thus maintaining the Builders Risk coverage. For example, construction delays, abandonment of the project, or obtaining insurance elsewhere do not signify that the property is finished or ready for handover, so they do not end the coverage in the same manner.
