The rental value of individual properties does not only depend on the physical characteristics but also on the environment that surrounds a building. Meanwhile, improper solid waste disposal reduced of rental value of properties. This study, therefore, examined the effect of dumpsite on residential rental value in Oluyole LGA Oyo state, Nigeria. A cross-sectional survey research design was adopted, relying mainly on primary and secondary sources of data. Using systematic random sampling technique, questionnaires were administered to 251 households in the selected houses within 200 meters radius of five (5) purposively selected dump sites – Olomi, Podo, Odo-Ona, Ile-Eja, and Dalute – all in Oluyole LGA. The selection of the dumpsites was based on the magnitude and its nearness to residential houses in the study area. Data were analysed using both descriptive and inferential (Pearson’s Chi Squared distribution) statistics at p value ≤ 0.05, while the qualitative data were content analysed. The study revealed that 46.6% of the respondents were males and 53.4% females. Majority (59.4%) of the households were tenants, while 29.5% were owner-occupiers. There was a negative relationship between annual rents paid by tenants of similar apartments with increasing distance from dumpsite. The observed variation in annual rent is significant at 5% significant level for all residential housing types (p < 0.05 for single room, room and parlour, 2-bedroom flat and 3-bedroom flat). The paper recommended a more proactive enforcement of sanitary laws and regulations of locating a dumpsite of 500 meter away from the residential environments.
