Determinants of leprosy events include the condition of residence. The aim of the study is to analyze the relationship between physical condition of house and sanitary facilities with the occurrence of leprosy. Methods: This study uses analytical observational research with a case-control study to analyze the relationship between the physical condition of the house and sanitary facilities and the incidence of leprosy in patients of Sumberglagah Hospital, Mojokerto. The sample size was 38, including 19 cases and 19 controls with simple random sampling. Research variables include individual characteristics, the physical conditions of the home, and sanitary facilities were analyzed using chi-square tests. Result: The results showed there was a significant relationship between physical conditions of house such as the ceiling, the type of floor, humidity, and density of the bedroom (p < α) with leprosy cases. Meanwhile, sanitary facilities do not show a significant relationship with leprosy cases.
