Post-disaster relocation, necessitated by housing destruction, displaces people from hazard-prone areas. While the new sites reduce exposure to hazard, the relocation also reshape residents’ daily lives. Relocation can involve an accessibility trade-off between reduced hazard exposure and access to services, despite being a commonly implemented Build Back Better (BBB) measures. Past research evaluated relocation impacts mainly on housing structural quality and hazard risk reduction. However, the existing evaluation frameworks have rarely assessed the impact of relocation on residents’ ability to access essential services. Following the 2018 Sulawesi earthquake, tsunami and liquefaction disaster, the Indonesian government introduced the Huntap (permanent housing) program, relocating over 11,000 households under the BBB framework. The majority of Huntap sites are located at the urban periphery of Palu City, raising questions about whether residents exchanged hazard exposure for spatial accessibility to daily services. This study aims to evaluates the extent of spatial accessibility changes from pre-disaster settlements to post-disaster relocation sites, focusing on essential urban services (e.g., markets, public transport, schools, mosques) and emergency facilities (e.g., hospital and evacuation sites). Using GIS-based network analysis, we assess changes in accessibility between pre-disaster origin zones (A0) and Huntap destinations (A1) based on weighted travel time score and Cumulative Opportunity Measure (COM). The difference in accessibility scores (ΔA) indicates the size of changes in accessibility at each site. It also shows whether accessibility has improved or declined, revealing variations in urban positioning across Huntap locations. Preliminary findings provide spatial evidence of an accessibility trade-off in Palu’s post-disaster relocation. The proposed method also provides a quantitative measure for evaluating the relocation outcomes of BBB implementation.
