The objectives were to explore the relation between the built environment of residence halls and the alcohol use of college students living on campus from the perspective of the theory of routine activity. This exploratory study examined data from two samples on one college campus. Online surveys assessed alcohol use, attitudes toward alcohol use, perceptions of campus alcohol norms, and individual factors (i.e., gender). Data came from an Alcohol Norms Survey using a random sample (N = 440) and a Resident Assessment Survey using a random sample ( N = 531) in 2006 and 2007. After controlling for other drinking behavior predictors (attitudes, gender, high school drinking, and perceptions of peer drinking), regression analysis showed that students living in suite halls had a higher odds of drinking more frequently, drinking more alcohol when they socialize, heavy episodic drinking, and drinking more often in their residence halls.
