sidential buildings are the most common scenario of fatal fires in Spain, and over the past decade, there has been no significant decrease of fatalities in this kind of accident, even a slight increase in recent years. In this context, a systematic methodology to evaluate the risk level of residential buildings, previously grouped into building typologies, is presented. Its application to different housing typologies allows covering large urban ensembles, providing an important information to regulators and fire services. The factors that most increase the level of fire risk are identified, analyzing them both by their construction stage and by their morphology.
