Most residents of the flats still carry the lifestyle of the landed house, such as hoarding goods. This case can be detrimental to the community during disaster evacuation. The evacuation process certainly does not always run smoothly. So obstacles and clogs may prolong the evacuation time and pose a risk of death. Therefore, it is necessary to study the risk of earthquake evacuation in vertical housing regarding the occupant's behavioral aspects. The case study is in three building blocks in Rusunawa Rancacili, Bandung. Weighting-based earthquake risk analysis is carried out through a calculation approach. Also, the disaster evacuation simulation approach requires a performance-based earthquake evacuation risk analysis. The disaster risk variables include threat, vulnerability, and capacity indexes. The threat is defined by weighting the ground acceleration around the site location. Determining vulnerability is done by social, economic, and physical vulnerability equation accumulations. Moreover, the capacity is acquired from the government's initiative in disaster management towards the site location and community contributions through a questionnaire with closed-ended questions. There are two scenarios for the evacuation simulation process, including with and free of obstacles scenarios. Evacuation simulations were carried out by agent-based modeling (ABM) using Pathfinder software. Then an interpretation is carried out to identify the factors that cause the level of disaster risk through the simulation results. The results showed that the level of disaster risk in Rusunawa Rancacili was moderate. Based on the weighting-based results, high social vulnerability and low capacity are the risk factors for earthquake evacuation. Meanwhile, based on the performance analysis results, interior and exterior obstacles and occupant characteristics are the risk factors for earthquake evacuation
