"Annually, from 2008 to 2010, fires in multifamily residential buildings accounted for an estimated 102,300 reported fires. These fires accounted for 28 percent of all residential building fires responded to by fire departments across the Nation. These fires resulted in an annual average loss of 400 deaths and 4,175 injuries as well as 1.2 billion dollars in property loss. Multifamily residential buildings include structures such as apartments, townhouses, rowhouses, condominiums, and other tenement properties. Multifamily residential buildings tend to have stricter building codes than one- and two-family buildings. Many multifamily residential buildings are rental properties, and are usually required to comply with more stringent fire prevention statutes and regulations involving smoke alarms and sprinkler systems. As a result of the type of building, the more stringent building and code requirements, and the fact that more people live in the building itself than in the predominant one- and two-family residence, fires in multifamily residential buildings tend to have a different profile than fires in other types of residences."
