The exposure of human settlements to the impact of forest fires is a topic of special relevance for urban planning. We conducted a study in San José de Maipo (Chile) as an example that illustrates the level of vulnerability of houses and other buildings potentially exposed to fire emergencies. A census of houses in the study area was carried out to determine the spatial distribution of wildfire hazard. At the same time, an analysis was made of the construction standards and state of readiness of critical infrastructure. The results expressed in the mapping of the risk level indicate high values in the urban-forest interface and the urgent need to update municipal plans and ordinances, especially for the treatment of combustible plant material in areas of direct contact with houses and other buildings. This is an aspect that is repeated in practically all the municipalities of Chile and that needs to be reviewed to improve the forest fire protection plans.
