The National Fire Protection Association (NFPA) reports annually on large-loss fires and explosions that occurred in the United States the year before. Those fires are defined as events that result in property damage of at least $10 million. Its latest report is "Large-Loss Fires in the United States 2016." The report included 10 large-loss commercial fires, which are listed below in order of dollar loss.

California (March 2016)
This was a one-story, 70,000-square-foot (6,503-square-meter) warehouse containing textiles. No information was reported on its construction, operating status, or fire protection systems. The building contained baled materials and textiles, creating a large fire load. There was partial collapse of the roof and front wall of the structure.

This was a one-story, 561,000-square-foot (52,119-square-meter) warehouse containing various products as well as food items, and was of protected, noncombustible construction.
