The preservation of heritage buildings presents a challenge in protecting cultural and historical value while maintaining structural integrity and functional usability. This research examines old timber mosques in Negeri Sembilan, Malaysia, which are increasingly threatened by decaying materials and insufficient safety protocols. The aim is to evaluate the existing safety conditions and preservation methods of these heritage structures. A qualitative case study approach was employed to examine five mosques through field observations, systematic safety assessments, and semi-structured interviews with interested parties. Identified key issues encompass timber degradation, fire risks, outdated electrical systems, and limited emergency access. The results indicate an absence between conservation initiatives and safety regulations. This study emphasizes the necessity of including systematic safety assessments into historic conservation frameworks. It promotes a balanced strategy that maintains traditional authenticity while fulfilling contemporary safety standards, highlighting the need for community involvement in achieving sustainable heritage management.
