The preservation of heritage building is very important, so it is necessary to carry out a building risk assessment in order to determine the safety limits of the building. This study aims to carry out a risk assessment of flood disasters in heritage buildings in the city of Semarang. The methodology used is a risk assessment carried out with a Risk assessment instrument from the guidelines of the BNPB which is elaborated with several previous studies conducted on 6 case studies of heritage temple building in Semarang City. The variables used in this risk assessment are flood hazard, vulnerability (involving of proximity to the river, building area, building elevation, building materials and conditions), and capacity.
