"Zoning and land use laws are fundamental to the make-up of our communities and our neighborhoods, but understanding these regulations and how they vary within and between places is enormously challenging. In large part, that’s because we lack straightforward, nationwide data.
To help solve this problem, we used publicly available information to build the National Zoning and Land Use Database (NZLUD). The database describes key elements of zoning codes and the limitations they impose for over 2,600 municipalities across the U.S. This includes previously available measures like minimum lot size and maximum permitted density, but also new items such as minimum parking requirements and maximum building height restrictions. We view the database as a living, evolving resource. The code and data are publicly available for anyone to access and build on."
