It has become increasingly important to evaluate housing property for many reasons. The attempt to enhance the aspect of safety planning in developing low cost houses is still neglected and one of the reasons that may contribute to this factor is due to the low price value. Hence, this paper emphasizes the application of Post Occupancy Evaluation (POE) that incorporates participation from the occupants as a tool to assess the safety performance of the Malaysian low-cost housing. The main aim of this study is to develop a framework of POE integrated with safety elements for Malaysian LCH. The inspection survey and occupants' satisfaction survey were carried out to 24 low-cost housing projects located in the federal territory of Kuala Lumpur, Malaysia. The correlation result revealed that all attributes between the safety performance and the occupants' satisfaction had a significant relationship. This also manifests the occupants’ feedbacks which were fed into the assessment of the housing safety performance.

INTRODUCTION housing for the citizens will be undertaken through collaboration between the state Housing conditions constitute one of the most governments and private sectors through common quality of life indicators.

The majority of low-cost housing fulfillment of the functional and the occupants’ (LCH) studies in Malaysia incorporated the needs. Aptly, the impact of strategies in dealing occupants’ feedback for determining their with the safety issues based on the building satisfaction on the layout design of the houses occupants’ experiences needs to be measured.
