xiv, 165 p. ： ill. (some col.) / Our current focus on the city core includes reintroducing the mixed-use building. This typology is not without challenges, and arguably none is more pressing than full retail occupancy. This analysis investigates the potential for start-up companies to supplement traditional retail on an interim basis. By documenting the needs and expectations of the start-up and development communities (from multiple perspectives), this study assesses the potential connection between mixed-use and the start-up company. Using a methodology informed by literature and augmented by personal accounts, this analysis reveals that the inclusion of start-up companies in mixed-use projects can present both short- and long-term benefits to ongoing retail difficulties: mixed-use buildings can be an ideal location for start-up firms, including start-up tenants can be economically feasible if certain measures are in place, and a new development model is not needed to connect an emerging business with an existing project. / Committee in charge: Howard Davis， Chairperson； John Rowell， Member； Gerardo Sandoval， Member
