This research explores the recent practice of connecting on-site carsharing service with off-street parking standards in multifamily developments; the San Francisco Bay Area, California, is used as a case study. If implemented well, such a policy could help boost the carsharing industry and reduce off-street parking, which is often criticized as being oversupplied as a result of excessive off-street parking standards. In 2011, the authors surveyed all carsharing sites in the Bay Area and all new residential developments (completed after 2000) with on-site carsharing spaces. The results showed that a significant number of carsharing spaces were located on residential properties, but 70% of the spaces had been retrofitted into existing buildings. For the new developments, on-site carsharing did not result in a reduction in the amount of regular off-street parking. Interviews with 15 professionals from three stakeholder groups (planners, developers, and service providers) revealed that even though all the stakeholders were in favor of on-site carsharing at residential developments, three major barriers existed: a lack of incentives, the complexity of access design, and high transaction costs.
