Insufficient opening of area for the natural ventilation which could lead to deterioration of Indoor Air Quality (IAQ). Numerous problems may occur due to improper natural ventilation in a building especially residential building. Insufficient of opening will also resulting to inadequate good indoor air and poor air circulation. This research is aimed to assess and identify the natural ventilation level of terrace houses in Kelantan in order to check the compliance with Uniform Building By-Law UBBL 1984. Three terrace houses were selected as case studies and the provision of natural ventilation for these houses were checked according to UBBL 1984. This research is based on data obtain from the measurement of spaces and opening of selected case study in Kelantan. The research concluded that the size and quantity of the window opening will influence the area of natural ventilation (%) in a space. The result of the study found that enforcing the UBBL compliance is needed for the purpose of obtaining building construction permits. This study also proposed that enforcement be used after the project has been completed, rather than just for the purpose of obtaining permission during the design and construction stages. It is hope that the study helps to get better understanding on natural ventilation and its standard requirement specified by the UBBL.
