Off-campus housing gives students a chance to attain independence toward their personal development because they are not under the control of either parents or the institution’s rules and regulations, more or less on their freedom and independence. The study aimed at examining the impact of off-campus accommodation on students’ social behaviour in Niger state polytechnic, Bida campus. Descriptive survey was adopted, using sample size of 138 students living in various off-campus lodges, chi-square was used to test the formulated hypotheses and the result showed that there is no significant relationship between off-campus accommodation and students’ social behaviour such as independence, freedom, personal growth and development. Conclusively, it is fundamental for all tertiary institutions and stakeholders to consider and prioritise student housing to ensure adequate and good student houses are provided. The management of the polytechnic should take extra measures to monitor the activities and behaviours of students living on campus since there is no significant difference between the behaviours of students living off–campus and their counterparts living on campus.
