Cities across the country have dropped the ball when it comes to planning for and building housing at all income levels — especially housing affordable to low-income residents. In response, many states have intervened. The form these interventions take varies from place to place, however, with Northeastern states relying on legal appeals by developers to deliver low-income homes, and Western states mandating local planning processes to achieve similar ends. How is that going? Professor Nicholas Marantz and Dr. Huixin Zheng join us this week to discuss the strengths and weaknesses of these different approaches, and reforms that could make them work better.
