Indonesia is located in hot humid climate area. Malang city becomes location of the research, which astronomically lays in 112.06o 112.07o East Longitude and 7.06o 8.02o South Latitude. The requirements of buildings construction in the climate are the availability of natural lighting system and cross ventilation. Buildings on the limited land sometimes can not meet the requirements. On Small Type Residences (STR), buildings renovations are mostly maximized to meet rooms need. The issue of the research was high humidity level in renovated STR. The research aimed to find out relative humidity performance in humid rooms. The research method used 9 temperature and humidity sensor for 24 hours on plafond, mid-air, and floor area in the conditioned rooms. Based on the measurement, they showed high rooms humidity in general. The rooms relative humidity performance changed based on its time and level to the floor. The plafond area had the lowest level of humidity, while floor area had the highest one. The research results are used as the basis to evaluate STR design in order to meet the best thermal comfort.
