The use of technology and social media has created an opportunity for the emergence of a "sharing economy." Sharing economy businesses include: car sharing, ridesharing, shared housing, and shared workspaces. They connect people offering a supply of goods/services with users who seek goods/services. These sharing economy businesses can present regulatory challenges in that many cities do not have regulations addressing these business models. Accordingly, cities struggle to fit these businesses into their existing regulations. This presentation will discuss the sharing economy, how cities can respond to issues and opportunities that these businesses present, and the related land use and public safety issues.
