We report results from a new survey of local residential land use regulatory regimes for nearly 2,500 primarily suburban communities across the United States. Key stylized facts are documented and compared to findings from a previous survey (Gyourko, Saiz, Summers, 2008). We are able to observe how the local regulatory environment has changed in over 800 communities in both samples. This represents the first consistent nationwide data documenting changes in residential land use regulation at the local jurisdictional level. Finally, we discuss how these changes can and should broaden the research questions for housing and urban economists investigating the local residential land use environment.

我们报告了一项针对美国近2500个主要郊区社区的本地住宅土地使用监管制度的新调查结果。记录了关键的风格化事实，并将其与以前的调查结果进行比较（Gyourko，Saiz，Summers，2008年）。在两个样本中，我们都能观察到800多个社区的当地监管环境发生了怎样的变化。这是全国第一个一致的数据，记录了地方管辖范围内住宅土地使用法规的变化。最后，我们讨论了这些变化如何并且应该扩大住房和城市经济学家对当地居民土地使用环境进行调查的研究问题。
