Amid the U.S. housing affordability crisis, parking minimum reforms are gaining momentum as states and municipalities seek ways to expand the housing supply. Parking minimum rules require housing developers to provide a specified number of parking spaces based on the number of new units to be built. Critics argue that the resulting extra construction costs constrain housing development and affordability. Although an increasing number of governments are reducing or eliminating these requirements, the pace of progress has been gradual due to localized opposition. One of the latest proving grounds for parking minimum reform is the U.S. capital Washington, DC, where momentum is growing for citywide elimination of minimums. Washington Core spoke with Dr. Yesim Sayin, Director of the DC Policy Center, about the unique situation in the District of Columbia.
