Abstract

Inclusionary housing (IH) ties the creation of affordable, below market-rate units with new development, and it is known to help address the affordable housing crisis and build inclusive communities. Yet, the absence of a national IH database limits our understanding of the prevalence, practice, and production of inclusionary housing in the U.S., and it creates barriers for further investigation and development of this affordable housing strategy. This study draws a national census of IH programs in the U.S. Through a comprehensive data collection between 2018 and 2019, a total of 1,019 local IH programs are documented in 734 local jurisdictions of 31 states and the District of Columbia. This study summarizes program design nationwide and features distinct patterns in California, Massachusetts, and New Jersey, where state laws largely impact program adoption and production. A subset of 258 programs reported producing about 110,000 inclusionary units, and 123 programs have collected close to $1.8 billion in fees for affordable housing development.

摘要

包容性住房 (IH) 将创造低于市场价格的经济适用房与新开发项目联系起来，众所周知，它有助于解决经济适用房危机并建设包容性社区。然而，国家 IH 数据库的缺乏限制了我们对美国包容性住房的流行、实践和生产的了解，并且为进一步调查和制定这一经济适用住房战略造成了障碍。本研究对美国 IH 项目进行了全国普查，通过 2018 年至 2019 年间的全面数据收集，记录了 31 个州和哥伦比亚特区的 734 个地方管辖区总共 1,019 个地方 IH 项目。这项研究总结了全国范围内的项目设计，并以加利福尼亚州、马萨诸塞州和新泽西州的独特模式为特色，州法律在很大程度上影响节目的采用和制作。据报告，258 个项目中的一部分已生产约 110,000 个包容性单元，123 个项目已收取近 18 亿美元的经济适用房开发费用。
