The aim of this study is to propose the decisionmaking in selecting the optimal reuse of pre-war shophouses by considering the importance criteria that are influenced the adaptive reuse process. A questionnaire survey among four (4) selective respondents consist of town planner from local authorities, valuer from valuation and property service department (JPPH), architects and building owners conducted to achieve the objectives. From the analysis, five (5) potential new uses which are new shophouses, pharmacy hotel, rental house anda restaurant were identified as a very suitable. Thirty-three (33) criteria were classified into six aspects which are economic, environment, social, architecture, technology, and legislative.
