The Architectural Administration Evaluation, conducted annually since 1999 under the “Building Act,” underwent a comprehensive reform in 2016. Nevertheless, concerns remain about excessive documentation requirements that burden local government officials, and there are ongoing questions about whether evaluation results are effectively translated into tangible improvements in architectural administration. While changes in the evaluation environment call for improvements—particularly in areas such as conducting performance-based evaluation focused on public satisfaction, providing feedback on evaluation results, and reducing the burden on evaluated agencies through efficient operation and management—the architectural administration evaluation has seen only modest improvements, such as adjustments to partial indicators, without a comprehensive review of the overall evaluation system. Therefore, this study aims to comprehensively examine the architectural administration evaluation’s indicators and the results of institutional operation since the 2016 reform, and to propose improvement measures for the operational system that align with the changed conditions of architectural administration.
