Fire Estimate Summaries present basic data on the size and status of the fire problem in the U.S., as depicted through data collected by NFIRS. Each Fire Estimate Summary addresses the size of the specific fire or fire-related issue and highlights important trends in the data.
A structure is a constructed item of which a building is one type. The term residential structure commonly refers to buildings where people live. To coincide with this concept, the definition of a residential structure fire includes only those fires confined to an enclosed building or fixed portable or mobile structure with a residential property use. Such fires are referred to as residential buildings to distinguish these buildings from other structures on residential properties that may include fences, sheds, and other uninhabitable structures. Residential buildings include, but are not limited to one- or two-family dwellings, multifamily dwellings, manufactured housing, boarding houses or residential hotels, commercial hotels, college dormitories, and sorority/fraternity houses.
