Impact of the 2025 Building Standards Act Revision on the Preservation of Historic Buildings

This study examined the impact of the 2025 Building Standards Act revision on buildings within Important preservation districts for groups of traditional buildings and assessed local governments' initial responses and awareness. Currently, the response remains unclear, but it is highly likely that renovations and utilization of buildings within Important preservation districts for groups of traditional buildings will be curtailed. Furthermore, the burden on owners may increase, including in terms of procedures and costs. In response to these issues, the need for national guidelines and coordinated efforts between local governments, architects, and other stakeholders has become evident.
