The Mamuju earthquake on January 15, 2021 damaged several buildings in Mamuju City. The epicenter is approximately 34 km from the city. According to BMKG, the intensity of the earthquake in Mamuju was VI MMI with a recorded peak acceleration of the earthquake vibration of 150 gal (1.5 m/sec2). There was damage that led to the collapse of many buildings, so it was deemed necessary to conduct an assessment of the buildings in Mamuju. In this paper, modelings are carried out for the surveyed buildings that represent moderate damaged and minor damaged buildings. Some of buildings were built before year 2010, therefore the standard used for designing the building was SNI 1726 2002. In this SNI, Mamuju City is still in the low earthquake zone category. In the SNI 2012 and 2019 standards, the Mamuju city is in higher earthquake hazard. The modeling of buildings built that refered to 2002 and 2019 standards needs to be carried out for better understanding and possible retrofitting
